Musa Unmehopa
Musa Unmehopa is the
Secretary General of the
Zhaga Consortium,
a global lighting-industry
organization that is
enabling interchangeable
LED light engines. Musa
has been involved in
standardization across
several industries for
almost 20 years, serving in
various chair positions and
directorships. He is on the
Board of Directors of the
ZigBee Alliance (intelligent
control for connected
lighting) and the EMerge
Alliance (standardizing
low-voltage DC power
distribution). Musa
received an MSc degree
from the University of
Twente, as well as MBA
degrees from TiasNimbas
Business School in the
Netherlands and Bradford
University School of
Management in the UK.
Every industry in transition needs to
successfully overcome a number of
challenges as it pursues growth and
profitability for all its stakeholders.
Four years ago, the Zhaga Consortium
was founded when a number of leading
companies in the lighting industry
identified a challenge as a result of a
rapidly developing LED market, i.e. the
proliferation of form factors for LED light
sources. Since its conception in 2010,
Zhaga has addressed this industry
challenge by developing 8 Books,
which specify the mechanical, thermal,
photometric, electrical and control
interfaces between LED light engines
(LLEs) and LED luminaires. These
Books address both indoor as well as
outdoor applications, and cover
socketable and non-socketable LED
modules, with an integrated or separate
electronic control gear (or driver). At the
Light + Building show in Frankfurt in early
April, Zhaga modules were ubiquitous
across the trade show floor. Despite the
accomplishment of the current Books
and the successful introduction of over
160 certified products on the market,
Zhaga cannot rest on its laurels. Zhaga
must continue to respond to the
evolving needs of the industry.
At its recent member meeting in
Amsterdam, Zhaga started the
development of three new Books.
The new Books are designated
numbers 9, 10 and 11. Zhaga Book 9
will define the interfaces of an LLE
which consists of a non-socketable LED
module with a ring-shaped light-
emitting surface (LES) and a separate
LED driver. Book 9 will cover small,
mid-power LED modules which could
enable LED luminaire products for use
in consumer lighting applications, such
as small spotlights, track lighting and
other compact luminaires.
Book 10 and Book 11 will both describe
LLEs that consist of a circular, non-
socketable LED module with a separate
LED driver. The modules have a circular
LES and are suitable for spotlight-type
applications. Both Book 10 and Book 11
are similar to Book 3, which is already
published and is one of
the most
widely-adopted Zhaga Books in the
industry with the most commercially-
available certified products.
Compared to Book 3, the new
Book 10 will describe larger, higher-
output LED modules with a larger
diameter, while the modules in
Book 11 will have a smaller diameter
and smaller thickness.
Furthermore, Zhaga has decided that
it will aim to enable LED modules and
drivers that are independently
interchangeable, by defining the
electrical interface between the
module and the driver. Today, for LED
light engines having a separate driver,
it may not be possible to interchange
LED modules from different suppliers
without also using a different driver,
or vice versa. However, Zhaga identified
clear signals from the industry that
there is now a growing market need
for LED modules and LED drivers that
are independently interchangeable
(i.e. you can interchange one without
necessarily interchanging the other).
This initiative will take the industry one
step closer to full interchangeability at
the component level.
As well as continuing to look at new
proposals from members, Zhaga has
also initiated a project to evaluate the
use of LED light engines across a
wide range of lighting applications.
The goal is to identify opportunities
and set priorities for the development
of new specifications that will provide
most benefit to the LED lighting
industry. Zhaga welcomes
requirements and feedback from a
wide range of interested companies
and organizations, both inside and
outside Zhaga.
These are exciting times of change
which pose a number of challenges
that need to be addressed head on.
I invite you to join Zhaga on its
mission to accelerate the adoption
of LED lighting solutions in the
marketplace, through standardization
of LED light engine interfaces.
Sign up as a Zhaga member and
help shape our industry!

Lextar Debuts
White Chip LED
Lextar Electronics Corp., a vertically
integrated LED company, announced
packaging-free “White Chip” to demonstrate
its new achievement in LED technology.
This new White Chip LED was demonstrated
at “Light + Building Frankfurt 2014” by various
LED lamps, including a 50-watt halogen
equivalent GU10 LED spot lamp, point-light
candle lamps, and omni-directional LED tubes
featuring ultra-high efficiency.
Lextar’s new White Chip technology involves a
substrate-free flip chip and phosphor molding
Lextar’s new White Chip technology involves a
substrate-free flip chip and phosphor molding
process, and can be fabricated by current
SMT equipment; all these features can
simplify the manufacturing process
significantly. Lextar’s White Chip is a chip
scale die without the packaging process.
It features high lumen densities, high lumen
output, wide beam angle. It can be packaged
closer and therefore simplify optical lens
design. Lextar’s White Chip can be applied to
lighting products, especially small sized lamps
such as spot or candle lamps. It can also be
applied to backlighting, helping reduce the
thickness of direct-lit backlight modules.
To demonstrate Lextar’s synergy of vertical
integration, Lextar brought various lighting
applications with its White Chips implemented
to Light + Building 2014. When used in a
GU10 spot lamp, this White Chip can achieve
high lumen output and high lumen intensity;
reaching up to 2500 cd at 25 degrees with
high CRI 90 performance, making it a perfect
replacement for a 50-watt halogen lamp.
The White Chip point-light candle lamp has
identical glowing effects to starlight and
creates an exquisite indoor setting.
Moreover, the light tube equipped with White
Chip and COG (Chip on Glass) technology, on
the other hand, allows for a 360-degree
illumination, reaching an ultra-high efficiency
of 200 lumens per watt.
Since LED companies have been eager to
attempt simplified manufacturing processes
at reduced costs during the past few years,
flip chip and packaging-free LED products are
getting more popular. The Company expects
to move this newly launched White Chip onto
the market during Q2 of this year.

Samsung Introduces
Flip Chip LED
Package and Module
Samsung Electronics Co., Ltd., a world leader
in advanced component solutions, introduced
a new lineup of flip chip LED packages and
modules offering enhanced design flexibility
and a high degree of reliability. The new
offerings, for use in leading-edge LED lighting
such as LED bulbs, MR/PAR and downlights,
will be available in the market during the
second quarter 2014.
Samsung presents Flip Chip on Module (FCOM)
for cost efficient high efficacy lighting solutions
Samsung’s new flip chip (FC) LED package
and flip chip on module (FCOM) solutions
feature highly efficient and versatile LED
structures, created by flipping over blue LED
chips and adhering phosphor film to each of
them. Samsung’s FC package technology can
produce LED packages down to a chip-scale
size without any mold, enabling more
compact lighting fixture designs.
Samsung’s new FC and FCOM series can be
driven at a current higher than that of
conventional LED components, and have low
thermal resistance. The low thermal
resistance improves the reliability of the FC
and FCOM solutions, resulting in higher flux,
and a decrease in the number of packages
needed, plus a reduction in the size of the
circuit board.
Also, by attaching a cell film, each package
gains uniform thickness and lower color
deviation. As a result, the FC and FCOM
solutions provide a high level of color
consistency and ensure the chromaticity
control of MacAdam 3-step ellipses.
The new FC and FCOM LED solutions include
a middle power LED package (LM131A), a
high power LED package (LH141A) and an
LED downlight module.
Flip chip mid power LED package (LM131A)
and high power LED package (LH141A):
Samsung’s LM131A and LH141A flip chip
packages feature exceptionally compact form
factors of 1.22x1.22 mm and 1.4x1.4 mm,
respectively. By excluding a plastic mold, the
two packages can function at a high current
level in a highly reliable manner, even after
long hours of use. These advantages make
them ideal for use in LED lighting applications
requiring a small form factor with high light
output, including LED bulbs and spotlight
products such as MRs and PARs.
Flip chip on module (FCOM) for LED
downlight fixtures:
Samsung’s new FCOM downlight products
are distinguished by their high light output.
Compared to a chip-on-board (COB) engine,
which has a fixed wattage, the new FCOM
permits simple adjustments in the number of
FC LED packages to make the module
compatible with a variety of electrical drivers
of different wattages, in allowing greater
design flexibility.
To create a downlight with 1000 lm output
and 100 lm/W efficacy, Samsung FCOMs
require a 1.7x1.7 cm circuit. Such a small form
factor makes these FCOMs well-suited for
size-sensitive LED lighting applications, which
include LED bulbs, MR/PAR spotlights,
downlights and even cove lighting.
Samsung’s FCOMs can support MacAdam
2-step depending on customer needs, thanks
to the superb color consistency of the chips
and a rating of at least 80 on the color
rendering index (CRI). The new Samsung
FCOMs also offer a range of correlated color
temperature (CCT) – from 2700 to 5000 K.
Luxeon 3535 2D Mid
Power LED Update
Boosts Performance
The Luxeon 3535 2D has increased its typical
flux output by 10%, delivering optimized
performance in combination with the quality
of light needed for distributed light source
applications. Specifically, for Luxeon 3535 2D
2700 K 90 CRI parts, typical flux levels have
increased from 55 lm to 61 lm. Simultaneously,
typical voltage has been lowered - resulting in
an efficacy increase of more than 10%. This
increase in performance will drive the
adoption of LED lighting for consumer bulbs.
Philips Lumileds improved the performance of
the 2700 K / CRI 90 versions of their popular
Luxeon 3535 2D
This is in line with Philips Lumileds targeted
improvements in flux and efficacy for 90 CRI
warm white LEDs. Developed to address the
rapidly growing market for high color
rendering light sources, this boost in
performance of 90 CRI warm white emitters
mimics the color quality of traditional
incandescent bulbs. Increasingly, customers
seeking retrofit lamp solutions are specifying a
minimum of 90 CRI. For example, the
California Energy Commission is requiring
minimum 90 CRI and 50 R9 for light fixtures
installed in California.
Toshiba Shrinks
Package Size of
White LEDs
Toshiba Electronics Europe (TEE) has
launched a new series of ultra-small chip
scale package white LEDs for lighting
applications that can reduce the mounting
area by 90% compared to conventional 3.0 x
1.4 mm package products. The new TL1WK
series LEDs have been designed as light
sources for general lighting, including straight
tube lights, light bulbs and ceiling lights.
Toshiba’s GaN-on-Si based new LEDs for
general lighting applications reduce mounting
area by 90%
Issue 43 2014© 2014 LUGER RESEARCH e.U.
The new products utilize gallium nitride-on-
silicon (GaN-on-Si) process technology and a
new process technology that fabricates the
elements of a packaged LED on an 8-inch
silicon wafer. The LEDs are the industry’s
smallest in sub-watt class (0.25 to 0.5 W)
white LEDs, with a package size of just
0.65 x 0.65 mm, but they achieve a luminous
efficacy of 130 lm/W and superior heat
dissipation. Forward current is up to a
max. of 180 mA.
The new white LEDs make it possible to
achieve a narrow beam in small-size lighting
equipment and can contribute to innovation in
lighting design. The first device has a color
temperature of 5000 K and a color rendering
index Ra of 80, other color temperature
variations including 4000 K, 3000 K and
2700 K are also under development.

dimensions of 2.5x2.5 mm and wide beam
angles making these LEDs ideal for
applications that require uniform illumination.
SSC’s new Acrich MJT 2525 series is a
mid-power package with leading performance
and lumen density
At the heart of this new package is the
state-of-the-art chip technology from Seoul
Semiconductor and also optimized light
extraction from the package resulting in high
luminous efficacies.
MJT 2525 Data:
CCT [K]: 2600-3700
CRI [Ra]: 80
Size [mm]: 2.5x2.5
Forward Current [mA]: Typical = 40;
Max. = 60
Luminous Flux [lm]: @ 40mA = 95;
@ 60mA = 129

incorporates the Acrich-Multi-Junction
Technology with multiple junctions on a
single monolithic chip eliminating the usage
of multiple wire bonds between several dies
to create the high voltage architecture.
This construction vastly improves the
reliability of the LED package since it
reduces the potential number of failure
modes associated with wire bonds within
the LED package. This high voltage
architecture also enables the use of simpler,
more cost-efficient drivers, compared to
conventional LEDs. The improved efficiency
of the driver electronics also results in less
heat generated and fewer electronic
components used in the driver design
allowing more space for thermal
management within the luminaire.

Osram OS Soleriq P 9
with Twice the Light
from Half the Surface
For the first time, Osram is offering a chip-on-
board LED, the Soleriq P 9, which is suitable
for compact powerful spotlights such as the
ones used in retail outlets and museums.
The latest member of the Osram Soleriq family
produces 2000 lumen from a surface with a
diameter of only nine millimeters. Compared
with the existing Soleriq S 13, that is twice as
much light from an area half the size. Just one
of the new light emitting diodes is enough to
replace a 35 W HID lamp for spotlighting.
Osram Opto’s new Soleriq P 9 offers a luminous
flux of 2000 lm and a luminous efficacy of
100 lm/W from a light-emitting surface with a
diameter of 9 mm
Technical Data:
Package dimensions: 15 mm x 15 mm
Light-emitting surface: 64 mm²
or 9 mm diameter
Beam angle: 120°
Luminous flux (Tj = 85°C and 3000 K):
2000 lm
Luminous efficacy (Tj = 85°C and 3000 K):
100 lm/W
CRI: min. 80 and min. 90
CCT: 2700 K – 5000 K (CRI 80),
2700 K – 4000 K (CRI 90)
The P 9 has a light emitting surface with a
diameter of only 9 mm (64 mm²) which is
around 50 percent smaller than that of the
existing Soleriq S 13 versions but at 2000 lm
the LED delivers twice as much light with the
same efficiency. This high brightness is made
possible by the surface-emitting chips used.
Even at very high packing densities they can
produce high luminous flux with above-
average efficiency. The small light-emitting
surface means that extremely compact and
therefore lightweight optics can be fitted for
highly compact spotlights. The spotlights can
therefore be less cumbersome and more
cost-effective, while still providing the same
luminous intensity. The luminous intensity of a
35 W HID lamp, for example, can be matched
by just one LED. The Soleriq P 9 has been
designed for use in spotlights for directional
indoor lighting and in particular for shop and
museum lighting.
The new Soleriq is being tested and
measured at a temperature of 85°C to
simulate the thermal conditions in actual
applications as closely as possible.
Customers will therefore be able to directly
plan the use of the LED in their applications
and will not have to carry out time-consuming
appraisals based on data sheet values.
SemiLEDs ReadyWhite
Technology for High
CCT Uniformity
SemiLEDs Corporation, a global provider of
vertical LED technology solutions, announced
sampling and volume availability of the EV-W
series of white LED chips, providing LED
packagers with a vastly increased range of
capabilities while lowering production costs.
The new EV-W chips incorporate SemiLEDs’
proprietary ReadyWhite™ phosphor technology,
which delivers a highly uniform phosphor
coating across the emitter surface, greatly
increasing color precision and uniformity.
Issue 43 2014 © 2014 LUGER RESEARCH e.U.
SemiLEDs’ high-output, high-consistency
unpackaged white chips (inset) support the
development of creative new LED packages,
especially lower-profile implementations
The availability of high-output, high-
consistency unpackaged white chips offers
LED packaging and luminaire manufacturers a
wide variety of new COB and package
options by eliminating the phosphor
application from the packaging process.
Innovative package-level implementations can
include variable-CCT single-package
solutions, and greatly simplified RGBW,
WWRA, WWWR or WWGR solutions to
provide enhanced CRI and higher efficiency
red/amber/green augmentation.
EV-W LEDs, based upon SemiLEDs proven
EV product line, are available in high-power
40-, 45-, and 53-mil low-profile vertical chips
and can deliver up to 140 lumens with
efficacies of 130 lm/watt at 350 mA,
depending upon the chip bin and chosen
packaging approach. Standard CCT & CRI
options range from 6500 K & 70 CRI to
2700 K & 80CRI, and include distributions
as tight as ¼ of a standard ANSI bin.
Additional customization, including specialized
phosphor options, is also available.
Historically, manufacturers who assemble
LED chips into low profile packages have
been faced with a substantial challenge when
it comes to uniformity and cost issues. While
the industry has developed effective
techniques to evenly cover the blue chip in a
cavity-based package, current dispensing
and spray-coating techniques tend to deliver
a domed distribution rather than a flat, uniform
coating. While moving to a vertical-metal chip
solves the problem of blue leakage that would
typically emanate from the sapphire substrate
with a dispense-coated or spray-coated
horizontal chip, SemiLEDs ReadyWhite
technology additionally addresses the equally
important issue of uniformity.
The SemiLEDs’ EV-W chip series is designed
for manufacturability and rugged longevity
and is available with an option of gold/tin
(AuSn) metallization to support eutectic
bonding to further enhance thermal
characteristics. The SemiLEDs EV-W series
is RoHS compliant with production quantities
available now.

Bridgelux OLM -
Advanced IP Rated
LED Sub-System
Bridgelux, a leading developer and
manufacturer of LED lighting technologies and
solutions, unveiled the Bridgelux Outdoor
Lighting Module (OLM); a new line of LED
sub-systems which integrates optics,
environmental protection and the LED source
for roadways, parking garages and other
outdoor and industrial applications. OLM will
allow manufacturers to rapidly expand their
product lines while lowering costs.
The OLM Series is Bridgelux’s LED replacement
for the high pressure sodium lamp that may
reduce product development time by three to
six months
Outdoor applications, including roadways,
parking lots and flood lighting are some of the
fastest growing segments in the industry.
According to McKinsey & Company, LED
based outdoor lighting solutions are expected
to grow from six percent of the market ($10
billion USD) to 74 percent by 2020.
The new Bridgelux OLM Series incorporates a
number of key technology advancements and
features that will help luminaire manufacturers
develop a broad range of differentiated
outdoor lighting products with lower total
costs, faster time to market, and industry
leading energy efficacy.
The Bridgelux OLM Series is a reliable and
efficient platform that integrates a number of
fundamental components for building
solid-state luminaires into a single sub-
system. OLM reduces product development
time by three to six months, eliminating up to
$100,000 in R&D expenses. Building solid-
state fixtures with OLM can reduce
manufacturing time by five to seven days.
When compared to conventional high
pressure sodium systems, OLM can reduce
the manufacturing cost of outdoor solid state
lighting fixtures by 10 to 20 percent, and
reduce maintenance costs while lowering power consumption by up to
65 percent. Further, OLM has been specifically designed to enable
lighting manufacturers to reduce the overall bill of material cost of their
luminaires and deliver a best-in-class cost to the market.
OLM’s slim profile, impact resistant optics, and broad area lighting
capabilities make it the ideal platform for outdoor wall pack and flood

Philips inroduces a Luminous
Ceiling Predicted by Isaac
Asimov 50 Years Ago
Philips, the global leader in lighting, revealed an innovative luminous
panel that can cover a whole ceiling with homogenous white light.
In 1964 the professor of biochemistry, Isaac Asimov, predicted: “By 2014,
electroluminescent panels will be in common use, and ceilings and walls
will glow softly’’
Issue 43 2014© 2014 LUGER RESEARCH e.U.
Philips’ OneSpace luminous ceiling was
predicted by American author and professor
of biochemistry Isaac Asimov in a 1964 New
York Times article looking at the technology of
the future. He wrote that “By 2014,
electroluminescent panels will be in common
use, and ceilings and walls will glow softly.
The Philips OneSpace luminous ceiling
integrates LED lights with textile to create a
white light ceiling surface that hides the
source of light completely. The result is a
smooth and clutter-free ceiling that emits a
uniform and glare-free light. The emitted white
light recalls the feeling of natural daylight. It
can be dimmed, used as safety lighting and
also be connected to building management
systems enabling centralized control to switch
it on or off for greater energy efficiency.
No additional ceiling is required with Philips
OneSpace luminous ceiling that plays the dual
role of ceiling and light. It also meets all
building and safety requirements.
Philips’ OneSpace luminous ceiling is available
in customized sizes up to 10 x 3 meters,
providing a maximum freedom of design. It is
especially suited for car showrooms, flagship
retail stores and public spaces like airports,
hotels and conference facilities to create a
striking and calm space while also serving as
functional lighting.
Samsung Lens-
Attached Modules
Samsung Electronics Co., Ltd., a world leader
in advanced component solutions and LED
component technology, said that it has begun
mass producing a value-added line-up of
highly efficient lens-attached LED modules
(LAMs), for use in office LED lighting
applications that include linear and line
lighting, cove lighting and troffers.
The new LAM series makes use of technology
from Samsung LED packages for flat-TV
backlight units (BLUs)
Samsung’s LAM series embraces a state-of-
the-art concept in LED modules. The LAM
solutions are created by attaching lenses on
top of the LED packages in each module.
The lenses add wide beam angles for their
light sources using advanced optic
technology, so that each LED package
can brighten a space larger than that of
conventional packages.
The new LAM series makes use of
technology from Samsung LED packages for
flat-TV backlight units (BLUs). In 2012, when
LEDs became popular in BLUs for LCD TVs,
Samsung created LED BLU modules
combining lenses with LED packages to
increase overall light output.
Using a Samsung LAM solution adds more
design flexibility for a wide range of
luminaires. Unlike fluorescent and
incandescent lamps, conventional LED
lighting features individual LED packages,
each of which emits light. As a result,
depending on the distance between the
diffusion plate and the LED modules in the
fixture, the spaces between packages on the
module can appear as dark spots.
To prevent this, the diffusion plate has to
be placed further away from the module,
which unfortunately increases the thickness
of the fixture.
With the new Samsung LAM series using
diffusion-improving optic technology, the
diffusion plate can be placed much closer to
the module – as close as 35 millimeters, a
significantly smaller space than the 80 to 100
millimeters needed for conventional T5/T8
fluorescent tubes.

Non-Linear Curved
and Flexible Light
Guides from GLT
Global Lighting Technologies (GLT), the world
leader in edge-lit, LED-based light guides,
has increased their capabilities to include
non-linear curved light extraction
technologies, enabling the design of more
complex light guides.
GLT’s non-linear curved light extraction
technologies enable the design of more
complex flexible light guides
These non-linear light guides can be
integrated into a variety of products, from
overhead lighting and wall sconces to
automotive interior/exterior lighting such as
dome lights, passenger compartment lighting,
and daytime running lights, as well as white
goods and consumer electronics devices.
This new product capability was made
possible by two developments within the
company. The first was the development of a
thin film embossing process that allows
manufacturing of 0.25 mm or less thick
flexible light to be used in applications
requiring flexible or mechanically curved
products. The second was a change to the
manufacturing process of the optical
extraction features embedded in the light
guides, allowing injection molding while
creating the extraction features onto curved
surfaces for thicker light guides. These
developments allow GLT to custom design
the curvature of the light guides for various
applications, offering typical sizes from
0.25 mm to 4 mm thick and greater than 24”
in diagonal, depending on the application.

With a 6 mm x 4 mm footprint and an
off-board profile of just 0.6 mm, the AL8812
converter is comprised of a temperature-
compensated reference, a comparator, a
controlled duty cycle oscillator with an active
current limit circuit, a driver and a high-current
output switch.
The AL8812 features an input voltage range of
3 V to 20 V and an output voltage that is fully
adjustable up to 60 V. This wide operating
voltage range makes the device suitable for
medium-voltage LEDs and 12VAC lighting
applications, as well as dimmable
MR16 LED lamps.

Shut-down current is very low at less than
0.01 µA, typical, and its maximum output
switch current is 3.6 A. The converter is able
to deliver very accurate voltage and current
control by incorporating a precision reference
with a 2% tolerance.
By combining the AL8812 with its AL8807A
constant current step-down converter, Diodes
Incorporated has produced a two-stage
reference design for dimmable MR16 LED
lamps that provides good transformer
compatibility and low current ripple at a very
reasonable BOM cost.
Dialog Semiconductor
iW3600 with 1-100%
Dimming Range
Dialog Semiconductor introduced its latest
single-stage LED driver to address dimming
performance, heat and cost in high power,
dimmable solid state lighting applications.
The new 45 W output iW3600 seamlessly
dims from 100% down to 1% of measured
light with virtually no dead travel and offers
low pop-on current to turn light on at very low
dimmer levels (< 5% of light output).
Besides built-in configurable temperature
derating for predictable operating life, iW3600
offers a wide 1% to 100% dimming range with a
low pop-on current of < 5% of the light output
Key Features:
Output power: 45W
Single-stage design for low BOM cost
Built-in, configurable LED over-temperature
protection derating
Wide dimmer compatibility (TRIAC, digital),
automatic detection of dimmer type
Wide dimming range: 1% to 100%
Lowest pop-on current < 5% of light output
Configurable dimming curves compliant to
NEMA SSL 6 dimming standard
Meets global standards, including European
Union IEC61000-3-2
Zhaga hot-plug compliant
Low TDH < 20% with high PF > 0.92
The iW3600 also uses Dialog’s patented,
configurable over-temperature protection
(OTP) derating to tackle LED bulb lifetime
issues caused by excessive heat, while its
single-stage, digital design lowers Bill Of
Material (BOM) costs for lighting OEMs.
Designed for retrofit bulbs including external,
dimmable lighting ballast drivers and A19,
PAR and T8 bulb replacements used in
existing phase-cut dimmer installations,
the iW3600 incorporates Dialog’s patented
intelligent dimming control to provide
compatibility with a wider range of dimmers,
including TRIAC, digital and universal
dimmers. This technology uses digital
analytics to query the dimmer and applies
algorithms that automatically adapt to the
dimmer type.
Most power ICs are designed with thermal
shutdown, which simply shuts the IC down in
high temperature environments. This
procedure protects the IC, but not the LED
driver circuit, since most control IC shutdown
occurs well above safe operating
temperatures for electrolytic capacitors.
The iW3600’s built-in configurable
temperature derating technology monitors the
temperature inside the sealed SSL bulb and,
in high temperatures, automatically reduces
current drive to the LEDs in small, virtually
imperceptible increments, then seamlessly
restores brightness as temperature falls.
This results in cooler operation and helps
ensure a predictable and safer operating life.
The iW3600 meets or exceeds global
regulations for power quality and efficiency
with low total harmonic distortion (THD)
< 20%.and high power factor (PF) > 0.92.

Supertex Releases
HV9910C Universal
HB LED Driver
Supertex, a recognized leader in high
voltage analog and mixed signal integrated
circuits (ICs), released an additional package
option for the HV9910C. The Universal High
Brightness LED Driver is now available in a
lead(Pb)-free/RoHS compliant 8-lead SOIC
with heat slug package in addition to the 8L
and 16L SOIC packages.
Typical application circuit using the Supertex
HV9910C LED driver IC
Enhanced drop-in replacement to the
Open loop peak current controller
Internal 15 to 450 V linear regulator
Constant frequency or constant off-time
Linear and PWM dimming capability
Over-temperature protection
DC/DC or AC/DC LED driver applications
RGB backlighting LED driver
Back lighting of flat panel displays
General purpose constant current source
Signage and decorative LED lighting
The HV9910C is an open loop, current
mode, control LED driver IC that can be
programmed to operate in either a constant
frequency or constant off-time mode. It
includes a 15 – 450 V linear regulator which
allows it to work from a wide range of input
voltages without the need for an external
low voltage supply. HV9910C includes a
TTL compatible PWM dimming input that
can accept an external control signal with a
duty ratio of 0 – 100% and a frequency of
up to a few kHz. It also includes a
0 – 250 mV linear dimming input which can
be used for linear dimming of the LED
current. The HV9910C is equipped with
built-in thermal shutdown protection.
The HV9910C is ideally suited for buck LED
drivers. Since it operates in open loop
current mode control, the controller
achieves good output current regulation
without the need for any loop
compensation. Also, being an open loop
controller, PWM dimming response is limited
only by the rate of rise of the inductor
current, enabling a very fast rise and fall
times of the LED current. The HV9910C
requires only three external components
(apart from the power stage) to produce a
controlled LED current making it an ideal
solution for low cost LED drivers.
Diodes AL8807B
Simplifies LED
Lighting Design
Diodes Incorporated has introduced a
dimmable buck LED driver enabling a
reduction in component count and PCB size
in 12 V and 24 V LED lighting systems and
MR16-type LED lamps. The AL8807B is a
hysteretic driver with an integrated power
switch and operates at a switching
frequency of 1MHz. The output current is
set using a single external sense resistor.
Diodes’ new AL8807B driver IC simplifies the
driver design for 12 V and 24 V lighting systems
Issue 43 2014 © 2014 LUGER RESEARCH e.U.
Dimming is achieved by applying a fast digital
PWM signal to the driver’s control input. A low
voltage, applied to the same input, turns the
output power switch off. Lamp reliability is
ensured by the driver’s built-in over-
temperature, LED open-circuit and short-
circuit protection features.
By packaging the driver in a small footprint,
low thermal-resistance MSOP-8EP package,
a higher power density is achieved,
maximizing the permissible LED current over
a wider ambient temperature range. The
AL8807B delivers an LED drive current up to
1.3 A and operates between -40ºC to +125ºC
with an efficiency of 96%.
From voltage sources between 6 V and 36 V,
the driver will produce a constant current for a
chain of high brightness LEDs. Average LED
current accuracy is better than 5%, helping to
improve channel-to-channel matching and
meeting the requirements of most medium
voltage LED lighting products.
Dialogs iW3640 for
Simple 2-Channel

bring mood-enhancing ambiance to price-
sensitive SSL bulbs. The iW3640 2-channel,
25 W SSL LED driver offers a simple,
low-cost, dimmable color-mixing solution to
achieve warm incandescent-like dimming
while eliminating the need for a microcontroller
and dedicated power supply. This reduces the
bill of materials (BOM) cost for 75 W to 150 W
equivalent A19 SSL and PAR bulbs, as well
as 20 W to 45 W commercial dimmable
external lighting ballasts.
iW3640’s simple 2-channel color mixing
operation eliminates costs of MCU and power
supply, while temperature derating ensures
predictable operating life
Key Features:

harmonic distortion (THD) < 15%
Phase-cut dimming with wide dimmer
compatibility, automatic detection of
dimmer type
Wide dimming range: 1% to 100%
Meets global energy standards, including
European Union IEC61000-3-2
NEMA SSL 6 compliant
Zhaga hot-plug compliant
While typical LED bulbs retain the same harsh
white color as they dim, the dual driver output
of the iW3640 lets designers use amber LEDs
in parallel with the main white LEDs allowing
LED bulbs to gain warmth as they dim.
Dialog’s patented, built-in digital dimming
technology detects the dimmer type and
phase - automatically adjusting LED color
mixing in step with light intensity to provide
smooth dimming that closely matches the
warmth and ambiance of a traditional
dimmable incandescent bulb from bright
white down to warm amber, with flicker-free
dimming down to 1% of initial brightness.
The result is a much more intimate LED
lighting experience in residential and
commercial settings, where lighting plays an
important role in setting the mood.
Dialog’s digital dimming technology allows the
iW3640 to work with virtually all phase-cut
wall dimmers, including leading-edge (R-type
or R-L type) and trailing-edge (R-C type)
dimmers, as well as digital dimmers.
The iW3640 addresses bulb overheating
issues by including an over-temperature
protection (OTP) derating function. Additional
iW3640 safety features include LED open/
short circuit, over-current, current sense
resistor short-circuit, and input over-voltage
The iW3640 2-channel, 25 W SSL LED driver
offers a simple color-mixing solution to
achieve warm incandescent-like dimming that

m!Qbe - New
Controls Concept for
Modern Lighting
The m!Qbe makes it simple to control your
light. Its six faces reproduce six lighting
functions that can be easily selected by
placing the cube on the corresponding face.
Predefined favorite lighting situations as well
as the manual adjustment of color and
intensity are provided by the m!Qbe. It is
therefore much more flexible than a traditional
light switch but at the same time much easier
and faster to use than a smartphone app for
lighting control.
The system consists of the m!Qbe, the gateway
m!Base and the wireless charging station
m!Charger and offers a perfect connection
being compatible to the system of Philips hue
New lighting technologies bring reams of
options to vary personal lighting at home. An
easy and intuitive solution is needed to extend
or to replace traditional light switches in order
to use all these possibilities in daily life. The
team behind the m!Qbe was faced with that
very problem when one member’s grandma
visited them one day. She was amazed at the
colorful LED lamps and wanted to take them
home – until she got to know the control with
a smartphone app. That is why the young
startup from the Lighting Technology Institute
of KIT in Karlsruhe (Germany) deals with the
intuitive control of light. Now, with the m!Qbe
a light switch is available that offers both
access to all the options of modern lamps and
easy usage that is a lot of fun.
The m!Qbe features six functions to control
the light. Besides the off-state two faces serve
as manual adjustment of light color and
intensity. A simple rotation of the cube around
its own axis changes these parameters
individually. Once the preferred color and
brightness are chosen for one lamp, the next
lamp can be selected with a short touch on
the face or the current situation can be
transferred with a long touch to all lamps in
the room. The remaining three faces store
favorite lighting situations that can be
accessed directly by turning the cube to the
corresponding face. Thus it is easy to switch
on the suitable light for different situations
such as reading the newspaper or relaxing on
the couch. The m!Qbe is the perfect light
switch for everyone who wants to control their
lights quickly and simply. In addition, there is
always a surprise inside. It never gets boring
with the random lighting situations achieved
by shaking the m!Qbe.
The 77x77x77mm sized m!Qbe communicates
via Bluetooth to a gateway that is connected
to the local network. With its open source
software it will be possible to connect other
devices of daily life in a similar way, for
example, the audio system.
Broadens Trinity
Line Power Centers
LumaStream, the leader in low-voltage,
intelligent, LED lighting systems, announced
today that it has expanded its Trinity line of
remote power drivers for LED lighting, adding
an analog model with as many control zones
as power channels to give lighting designers
and system integrators ultimate design
flexibility. Lighting applications where 0-10V
controls are most common, but where only
small numbers of LED fixtures are grouped
together on one switch, can now have the
same variety of lighting configurations as a
digital, low-voltage system at the lower analog
system price point.
The expansion of the Trinity™ series brings new
flexibility to low-voltage LED lighting systems
LED is the fastest growing technology for
general lighting in commercial buildings.
LumaStream is the only company to offer a
holistic approach to low-voltage power
distribution for LED lighting. The Trinity 3-in-1
platform combines digital power conversion,
constant current drivers, and superior
dimming control into one cohesive, intelligent
LED power supply. Trinity remote drivers can
power and control up to 24 LED luminaires up
to 200 ft. away using only thin-gauge
speaker wire.
According to the U.S. Department of Energy,
onboard drivers are the number one source of
failure in LED fixtures. LumaStream eliminates
that failure point, combines power and control
onto one wire, and provides both analog and
digital control protocols.
The new Trinity Analog model is ideally suited
for hospitality and medical office applications
where standard analog control switches and
dimmers are used and where individual rooms
or spaces may have only one or two LED
fixtures that need to be powered or dimmed
at once. Both markets, hospitality and
healthcare, are experiencing growth in 2014,
leading in new construction numbers.
A first project to benefit from the new Trinity
Analog power supply is the St. Petersburg
College midtown campus. Opening later this
year, the new facility will incorporate
LumaStream low-voltage power distribution
and LED fixtures. Each administrative office
will have the familiar toggle switches and slide
dimmers for light control, but groups of
several offices will be able to be powered from
a single Trinity remote power supply. The
energy efficiency and infrastructure savings
are significant, while the system is easy to
install, configure, and commission. This saves
the college upfront investment and shrinks the
ongoing operating expense.

EM converterLED -
Emergency Light for
Standard LED Modules
With the EM converterLED product range,
Tridonic provides simple implemented
emergency light functionality with local battery
supply for standard LED modules. The
emergency light drivers feature reliable 3-pole
technology with compatibility to most LED
control units in the market. Thanks to power
control, the maximum output for specified
rated operating duration is always achieved in
emergency light operation.
Tridonic’s EM converters are available in three
versions, Basic, Selftest and DALI, offering
different function and duration test functionality
The product family consists of the versions
EM converterLED BASIC, EM converterLED
EM converterLED Types:
EM converterLED BASIC features
fundamental emergency light functions with
an appealing price-performance ratio. The
function test and duration test are carried
out manually, whereby the function test
must be implemented once monthly and
the duration test once each year.
EM converterLED SELFTEST features
self-test functions for the emergency
lighting installation. An indicator LED
positioned noticeably on the luminaire
housing displays the test results. Integrated,
automatic test routines in the emergency
light unit are implemented in compliance
with international standards for emergency
light operation.
EM converterLED PRO DALI represents the
high-end solution in the portfolio of
emergency light drivers. Tests can be
individually set via DALI x/e touchPANEL or
other DALI-compatible components for
each device. The test results are either
displayed with an indicator LED on the
luminaire housing or documented centrally,
e.g. on the DALI x/e touchPANEL.
Classification according to SELV classes:
All three versions are additionally subdivided
according to SELV classes. Luminaire design
is particularly simple up to a maximum of 60 V
forward voltage (EM converterLED 50 V – 10
to 50 V forward voltage), as no supplementary
measures are needed for protection against
accidental contact. Typical applications are
spots for example, operated with higher
current but with forward voltage below 50 V.
SELV applications to a maximum of 120 V
forward voltage (EM converter LED 90 V – 50
to 90 V forward voltage) cannot be touched
and are suitable for luminaires requiring higher
forward voltage. Typical applications are
single LED modules switched in series with a
nominal consumption of 20 to 50 W.
The non-SELV versions have been designed
for maximum output voltages of 200 V (EM
converterLED 200 V for 50 to 200 V forward
voltage). These are typically assembled in
linear and planar luminaires and also ensure
homogeneous light distribution with
emergency lighting.
The emergency light drivers are compatible
with standard dimmable and non-dimmable
constant current converters on the market,
and thanks to integrated power control always
ensure maximum output for the specified
rated operating duration (1 – 3 hours).
The emergency light driver identifies the
forward voltage of connected LED modules
and regulates the LED current to the
maximum possible value with which
connected batteries achieve the specified
service life. The power control function also
enables many different combinations of
LED converters and modules.

PhosphorTech Releases New
RadiantFlex Products
PhosphorTech has just released its latest RadiantFlex phosphor sheet
product series for ultra-high color rendering (CRI) LED applications
and, furthermore, has recently demonstrated a High Light Extraction
(HLE) version of its remote phosphor RadiantFlex sheet capable of
improving a white LED’s wall plug efficiency (WPE) by as much as 31%.
Comparison of the RadiantFlex and conventional phosphor technology
High CRI RadiantFlex Series:
The new products are available from “warm white” (CCT~3000 K) to
“cool white” (CCT~5500 K) versions with CRI as high as 96 using blue
LEDs between 450-455 nm. These products offer unmatched

luminous efficacies when compared to
competing technologies having similar CRI.
Such high performance is achieved by the
unique ability of the RadiantFlex
manufacturing process to accurately layer
different phosphors and achieve unique
spectral shapes while minimizing self-
absorption and scattering losses.
High Light Extraction RadiantFlex Series:
The new technology enables the thin remote
phosphor sheet to couple directly to the top
surface of a COB LED encapsulant using a
high performance silicone layer that can
withstand temperatures as high as 260°C.
This results in increased light extraction and
more effective thermal management that can
lower the phosphor operating temperature
and improve both efficiency and longevity.
The remote phosphor sheet can be die-cut
and applied to the LED surface using
standard pick-and-place equipment.
This technology has also been used to
demonstrate LED light engines with ultra-high
color rendering index (CRI Ra~97) with high
R9 in all colors ranging from “warm white”
(CCT~3000 K) to “cool white” (CCT~5500 K).
About the RadiantFlex Technology:
The most common usage of phosphors in
solid-state lighting (SSL) involves pre-mixing
micron-size particles with a polymer and
directly depositing the phosphor slurry on the
LED die. Unfortunately, such a traditional
approach results in lower wall plug efficiency
(WPE) due to optical scattering losses and
light trapping within the phosphor/polymer
matrix. Furthermore, as LED power increases,
this method becomes more limited because
of the significant thermal and optical loads on
the phosphor, which lead to further drop in
efficiency and performance at higher
temperatures and power densities. Therefore,
the remote phosphor approach becomes
more attractive.
The RadiantFlex technology and
corresponding patent-pending manufacturing
process are a direct result of over a decade of
research in various remote phosphor
application methods, phosphors, and
substrate materials.
Unlike conventional remote phosphor plates,
the RadiantFlex technology enables package-
level application of phosphor layers to blue
(and UV) LEDs. This removes the need for
expensive mixing chambers and external
reflectors and provides higher performance at
lower costs. The RadiantFlex approach also
eliminates the need for LED producers to
handle phosphor powders and invest in
expensive phosphor mixing and dispensing
equipment. This will result in considerable
R&D savings for LED and lamp manufacturers
who typically must spend significant time and
resources developing a custom phosphor
mixture for each application. As is well-known
in the SSL industry, achieving high CRI with
high luminous efficacy in white LEDs is a
complex process plagued with repeatability
and uniformity problems since it involves a
carefully controlled mixture of several different
phosphor compounds. The RadiantFlex
technology eliminates those problems and
enables detailed analysis and quality
verification of the phosphor layers prior to
integration with the LED. This results in
significant savings in terms of materials and
resources that are typically involved in any
new LED product development &

AI Technology, Inc. (AIT) introduces Cool-
Pad™ CPR7154, a new class of thermal
interface material that dispenses like a thermal
pad, but performs with characteristics like that
of a grease or gel when device temperatures
increase to above 45°C. Cool-Pad™ CPR7154
is optimized to accommodate large areas with
different heights and gaps of less than 3-mil
along its interfacing area. It is filled with a
modified oxide mixture and is electrically
insulating at normal voltage. It is designed to
have high compressibility as applied in
comparison to traditional thermal pads. Once
the device temperature reaches 45°C,
Cool-Pad™ CPR7154 will “melt-flow” to fill
even the smallest of trapped air along the
interface between the device and heat-sink or
AIT’s Cool-PadTM is simple to use and offers
high performance

Cool-Pad™ CPR7154 is semi-tacky on both
sides for optimum thermal transfer
performance. Cool-Pad™ CPR7154 has high
thermal conductivity and low Tg
characteristics that impose minimum thermal
stress on bonded parts during thermal cycling
or shock testing. While Cool-Pad™ has some
intrinsic tack strength; it is not designed for
bonding. A mechanical fastener must be used
to provide assembly integrity.
A mechanical fastener of 5 psi or more is
recommended to provide intimate contact
between the Cool-Pad™ and the interfacing
surface. Because Cool-Pad™ is
compressible, it will fill in uneven height
differentials and warps between the mating
surfaces. The ultimate performance of
Cool-Pad™ is achieved after the first cycle of
melt-flow phase-change at 45°C or
automatically when the device heats up during
operation or with externally applied heat if the
device is not anticipated to reach 45°C.
Cool-Pad™ CPR7154 is designed for thermal
interface applications to withstand the worst
of temperature and moisture exposure in
outdoor LED luminaire applications with
modules from different brands.
MechaTronixs Small
Spot Light LED Cooler
ModuLED Pico
As an extension to the success of the
ModuLED modular LED coolers, MechaTronix
developed a new era of passive LED cooling
in a diameter of 47 millimeters, named the
ModuLED Pico. The secret of the ModuLED
Pico can be found in the way that the ultimate
thermal performance has been reached in this
narrow diameter.
MechaTronix’s new ModuLED Pico with
its unique thermal design serves various
LED platforms
The ModuLED Pico has a unique thermal
design, based on the ideal balance between
creating cooling surface and generating
space for free air convection cooling.
Also the outer surface is extended to generate
extra radiation cooling. Radiation can count
for up to 40% of the total cooling performance
in free air convection environments, and
mainly depends on the visible surface and
the emissivity of the surface.
Even under a tilted position of 50 degrees the
cooling performance remains almost
unchanged. This makes the ModuLED Pico
the ideal cooling source for tiltable spot and
down light designs.
Two new versions are available and focus on
the medium LED spot and down light market
from 600 to 1,800 lumen. With a fixed diameter
of 47 mm and lengths of 50 mm and 80 mm
the ModuLED Pico have a thermal resistance
of respectively 5.2°C/W and 4.2°C/W.
The ModuLED Pico is foreseen as a variety of
standard mounting patterns for all the newest
generation LED modules and COB’s. In this
way lighting designers can standardize their
designs with a limited number of LED coolers.
Just mechanical compatibility is of course
not sufficient, so a thermal validation will be
necessary with a combination of the LED
module/COB and the cooler. Either the
application engineers from the brand partners
or MechaTronix’s LED design team offer
assistance on thermal compatibility questions.
PCB Terminal Block
for Small LED Modules
The 2059 Series compact SMD PCB terminal
blocks stand out thanks to their compact size,
their small pin spacing and a high rated
voltage, making them particularly well-suited
for small LED modules in spotlights,
downlights or street lights. The smallest
WAGO terminal block, with a mere overall
thickness of only 2.7 mm, is extremely flat,
covers a wire cross section range of AWG 26
to AWG 22 (0.14 to 0.34 mm²), for solid
conductors, and has pin spacing of 3 mm.
The PCB terminal block is designed for a
rated current of up to 3 A and a rated
voltage of 160 V.
WAGO expands its SMD family with the new,
just 2.7 mm high, extremely compact 2059
Series PCB terminal blocks
Design Benefits of the WAGO Terminal
The terminal block small size means it
requires less space for the connection
technology used. Its low profile, along with
its light color, reduces on-board LED
The terminal blocks are available as 1-, 2- or
3-pole versions and can be connected in
series without losing any poles. This means
that no extra terminal block versions need
to be kept on stock when a higher number
of poles is required - increasing flexibility
and reducing costs.
Use and handling is especially easy, as solid
conductors can simply be directly inserted
and also removed quickly using an
operating tool.
The PUSH WIRE® connection provides a
high-quality and maintenance-free
Besides the smallest terminal blocks of the
2059 Series, WAGO covers an extensive
range of applications with its 2060 and 2061
Series, up to maximum conductor cross
sections of 1.5 mm². The 2060 and 2061
Series terminal blocks are equipped with an
integrated push-button that can be used to
very easily connect fine-stranded conductors
and to remove the connected conductors.
The 2060 Series SMD PCB terminal blocks
are ideal for surface-mounted PCB
applications. Just 4.5 mm high and a
conductor cross section of 0.2 to 0.75 mm²,
these terminal blocks offer great benefits in
the smallest of space. The 2061 Series SMD
PCB terminal blocks have a cross section
range of 0.5 to 1.5 mm² and are perfect both
for industrial applications and for direct
feed-in of LED modules.
All SMD PCB terminal blocks are available in
tape-and-reel packaging for use in automated
machines, allowing them to be fully integrated
into SMT assembly and processing.

Molex Low-Profile
Lite-TrapTM SMT Wire-
to-Board Connectors
Molex Inc. announces its new Lite-Trap™ SMT
Wire-to-Board Connector System featuring an
overall compact size that meets the needs of
thin LED lighting-module applications.
Molex’s new Lite-Trap™ easy-to-use push-
button latch allows simple field assembly and
removal for manufacturers of thin LED lights
LED lighting manufacturers are continually
looking for ways to reduce component height
on their boards in order to achieve thinner
designs and minimize shadowing or
interference with the light source. Molex’s
push-button style Lite-Trap wire-to-board
connectors, with a profile height of just
4.20 mm, provides one of the lowest profile
and wire insertion forces available on the
market today compared to wire-removable
type connectors.
The termination method of the Lite-Trap
connector is similar to the established Wire
Trap connectors Molex introduced, as well as
certain ‘poke-in’ types, but requires a lower
wire insertion force. A stripped wire is inserted
into the connector and pushes open a
dual-contact gate-style terminal design that
traps” the wire, providing a secure electrical
contact and high wire-retention force. The
Lite-Trap connector also features a user-
friendly latch that is easy for operators to
engage and disengage without the use of a
tool. These features combine to offer easy
field assembly and removal if needed, even for
untrained technicians.
Other features of the Molex Lite-Trap
connector include a long wire insulation
design that provides stable wire placement for
additional contact assurance. In addition, an
innovative wire stopper feature facilitates
correct wire insertion depth placement.
Ideal Introduces
Compact Low-Profile
COB Array LED Holder
Ideal Industries, Inc., a leading supplier of LED
components to OEM light fixture
manufacturers, introduced the new Chip-
Lok(TM) Jr., a compact, low-profile version of
the company’s original Chip-Lok COB (Chip
On Board) array holder. The new Chip-Lok Jr.
provides improved design flexibility when
integrating smaller arrays into compact
fixtures and lamps.
Ideal named its new COB Array LED holder,
which is consistent with Zhaga size and
mounting parameters, Chip-Lok Jr.
The new Chip-Lok Jr., with its small footprint,
fits virtually any size fixture and is configured
to hold arrays from Cree, Citizen and most
other leading manufacturers. It helps OEMs to
lower system cost, increase reliability,
and bring their designs faster to market.
Measuring only 35 mm in diameter, the
Chip-Lok Jr. occupies approximately 50%
less area than the original. It stands 0.3mm in
height above the array to allow unmatched
access to LES for optics. Screw mounting
holes at 25 mm and 35 mm spacing further
enhance design flexibility. The size and
mountings are consistent with Zhaga
parameters, providing a means for OEMs to
standardize on luminaire components and
utilize COBs from different manufacturers.
The Chip-Lok Jr. holder is fabricated from
hardened stainless steel to prevent the
“creep” to which plastics are prone, assuring
greater thermal pressure for the life of the
luminaire. This metal frame also provides a
thermal path so the array can run significantly
cooler while offering superior structural
strength when compared to arrays mounted
using plastic holders. Because Chip-Lok Jr.
array holders help lighting manufacturers
reduce chip temperature, the OEM can
benefit from extending array life or reducing
the size of their heat sink.
Instrument Systems
Goniophotometer for
The LGS 1000 from Instrument Systems
allows angle dependent spatial radiation
characteristics of large LED modules,
solid-state lighting (SSL) products, as well
as lamps and luminaires to be determined.
The Munich-based company presented key
upgrades for its largest goniometer system
at this year’s Light + Building fair
in Frankfurt.
With Instrument Systems LGS 1000 and the
optional luminous flux integrator, the
measurements can be taken faster and are
more accurate
The LGS 1000 can be operated together
with a photometer as a conventional
goniophotometer or with a spectrometer
as a high-quality goniospectroradiometer.
This allows all important performance
characteristics such as luminous intensity
distribution curves, luminous flux, color
coordinates and even color rendering index
to be measured.
As an optional accessory, the newly
developed luminous flux integrator allows
the characteristics of lamps and luminaires
to be determined in their required burning
position. An added benefit is that the
measurements can be taken faster and are
more accurate. Furthermore, Instrument
Systems supplies an innovative correction
procedure for position-sensitive samples.
If a low-maintenance measuring system
with a compact footprint is a top priority,
the LGS 1000 together with correction of
the burning position provides a genuine
alternative to a large and expensive rotating
mirror goniophotometer.
Alongside the new accessory options, the basic version of the goniometer also offers
an array of advantages. Accessible steps allow samples up to 2 m in diameter and
weighing 50 kg to be easily mounted. Notwithstanding the robust dimensions,
the LGS 1000 can still be accommodated in a laboratory with a standard ceiling height.
The two synchronously controlled servo motors with precision angle encoders facilitate
simultaneous movement with minimal vibration. The reproducibility of the sample
positioning is smaller than 0.1° at nominal load.
The comprehensive SpecWin Pro software package offers easy evaluation and reporting
of the measured data. Alongside a turnkey solution for electrical drive and measurement
of samples, SpecWin Pro can generate the important IES and EULUMDAT formats for
the lighting industry.

LED MR16 Lamp
Smoothly Mimics
Halogen Dimming
Ledzworld, the innovator behind the top
brands in commercial LED lighting,
displayed a breakthrough color temperature
adjustable LED MR16 lamp that perfectly
emulates the color tones of halogen light
bulbs when dimmed at Light + Building.
Now users can create the right color
temperature ambiance through dimming
while enjoying the energy-efficient and
long-lasting benefits of LED lighting.
The second generation of Ledzworld’s “Color
Temperature Adjusted” (CTA®) dimming
technology allows a CCT range from 2700 K
down to 1600 K while adjustments can be made
to meet customers’ specific demands
Seen as a large barrier to wider adoption of
LED lighting, full-linear dimming has been
an obstacle for many manufacturers. LED
MR16 lamps on the market today simply
reduce light output when dimmed,
but maintain the same Correlated Color
Temperature (CCT) throughout the dimming.
This leaves much to be desired when it
comes to the ambience in a room.
Utilizing a second generation of the
company’s patented and award-winning
“Color Temperature Adjusted” (CT)
dimming technology, Ledzworld’s new
CTA 2.0 LED MR16 lamp not only adjusts the
light output strength while being dimmed,
but also gradually transforms from a bright
soft tone color temperature at the highest
level, to a warm flame color at the lowest
dimming level.
The CCT on the new lamp will range down
from 2700 K to 1600 K depending on the
dimming level, and adjustments can be made
to meet customers’ specific demands.

White Light from
Nanopyramid LEDs
Researchers of the Chinese Academy of
Sciences’s institutes of Semiconductors and
Mechanics, and Tsinghua University have
used nitride semiconductor nanopyramid
structures to create LEDs with spectra that
are similar to those provided by ‘white light’
LEDs with yellow phosphors [Kui Wu et al, J.
Appl. Phys., vol115, p123101, 2014]. A similar
CAS/Tsinghua team previously reported such
devices, using a polystyrene nanosphere
mask to make holes for selective-area
growth of nanopyramids.
The light-emitting structures are grown on the
semi polar facets of the nanopyramid. Growth
in semi polar directions of the crystal structure
should avoid electric field polarization and
strain-dependent effects that make the
growth of high-indium-content indium gallium
nitride (InGaN) difficult. High-quality high-
indium InGaN is needed to achieve longer-
wavelength light emission for ‘white light’.
The n-GaN template consisted of a 2 μm
n-type layer on 2 μm undoped GaN buffer on
sapphire substrate. A mask layer of silicon
dioxide was deposited and patterned using a
hexagonal array of polystyrene nanospheres.
The photoresist patterning created 400 nm
diameter holes in a 900 nm periodic array.
The pattern was transferred to the silicon
dioxide by inductively coupled plasma
(ICP) etch.
Metal-organic chemical vapor deposition
(MOCVD) then proceeded to grow the nitride
semiconductor material on the exposed
n-GaN template. The initial growth was
1050°C n-GaN for 4 minutes to form
nanopyramids with {10-11} facets. Next, a
five-period InGaN/GaN multiple quantum well
(MQW) was grown (720-780°C), followed by a
13 minute 950°C p-GaN layer. The resulting
nanopyramids were about 600nm high.
The photoluminescence spectra of the
nanopyramids gave two peaks around
445nm (blue) and 550nm (yellow).
The balance of the peaks depended on the
MQW growth temperature. In particular,
the higher-temperature growth increases
the blue relative to the yellow peak.
The researchers attribute this to the
decomposition of the yellow-emitting regions,
which have higher indium content.
When grown at 780°C, the nanopyramid LEDs
exhibit a spectrum which is similar to phosphor
converted white LEDs using yellow phosphors.
Microscopic inspection of ectroluminescence
showed that the blue radiation comes from
the apex of the pyramids, while the yellow
radiation comes from the base region which
has higher indium content and wider, less
quantum-confined wells, leading to a smaller
energy gap.
The researchers admit that the nanopyramid
radiation is still weak:, but believe that the
brightness can be improved by optimizing the
growth parameters, including the size, aspect
ratio, and the structure of MQWs.
Conventional LED fabrication processes need
to be developed to cope with the rough
surface of the nanopyramid structures.
The researchers are working on device
structures and chip processes that will enable
detailed electroluminescence characterization
of nanopyramid LED structures.
On the basis of finite-difference time domain
(FDTD) simulations, the researchers believe
that the nanopyramid arrays have a light
extraction efficiency about four times higher
than for conventional planar MQWs that suffer
from a small escape cone at the air-GaN
interface. The simulations give an escape
cone as high as 85°, compared with less than
40° for planar structures.
New Technique
Makes LEDs Brighter,
More Resilient
Researchers from North Carolina State
University have developed a new processing
technique that makes LEDs brighter and more
resilient by coating the semiconductor
material Gallium Nitride (GaN) with a layer of
phosphorus-derived acid.
By coating polar gallium nitride with
phosphonic groups, the researchers increased
luminescence without increasing energy input
(Image Credits: Stewart Wilkins)
By coating polar GaN with a self-assembling
layer of phosphonic groups, it is possible to
increase luminescence without increasing
energy input. The phosphonic groups also
improve stability, making the GaN less likely to
degrade in solution. More stable GaN is more
viable for use in biomedical applications,
such as implantable sensors.

photolithography. Right: (a) Room-temperature photoluminescence spectra of nanopyramid LEDs
with MQWs grown at different temperatures, along with reference structure grown on planar
template. (b) Spectrum of ‘white LED’ (blue LED with yellow phosphors). (c) Electroluminescence
spectrum of nanopyramid LEDs at 20mA; inset shows corresponding optical microphotograph
Issue 43 2014 © 2014 LUGER RESEARCH e.U.
The researchers started with polar GaN,
composed of alternating layers of gallium and
nitrogen. To increase luminescence, they
etched the surface of the material with
phosphoric acid. At the same time, they
added phosphonic groups – organic
molecules containing phosphorus – that
self-assembled into a monolayer on the
surface of the material. This layer further
increased luminescence and improved the
stability of the GaN by making it less likely to
react chemically with its environment.
Thick-Shell Quantum
Dot Technology to
Increase Brightness
Quantum Materials Corporation and Los
Alamos National Laboratory’s announced
Quantum Materials optioning Thick-Shell
‘Giant’ Quantum Dot patented technology
with the potential of 10 to 100-fold
improvement in solid-state brightness over
conventional nanocrystal quantum dots (QD).
High brightness leads to efficient use of
materials and increased performance in
electronic displays and solid state lighting.
“Blinking” is a tendency of quantum dots
to flash off momentarily often noted as a
challenge for certain quantum dot
applications. LANL scientists also
discovered that thick-shelling quantum
dots dramatically reduces fluorescence
intermittency by better separating
absorption by the shell and emission by
the core, significantly suppressing blinking.
Quantum materials optioning Thick-Shell ‘Giant’
Quantum Dot patented technology promises
improvement in solid-state brightness over
conventional nanocrystal quantum dots (QD)
Commercial product lifetimes can be
increased in QD-LCD backplane displays,
solid state lighting films and projection
lighting because the thick-shell technology
has demonstrated the ability to extend the
service life of quantum dots exposed to
higher temperatures and/or high intensity
light. Further, non-blinking quantum dots
that can produce higher light output with
less heat generation will spur new product
development and optimized design.
LANL also achieved thick-shell “Giant” QD
near-infrared (NIR) emission for a major
advance affecting medical imaging
applications, optoelectronics, lasers,
telecommunication and solar photovoltaics.
For example, targeted cancer cells will be
easier to identify and track, and varied
absorption and emission ranges offer
tailored performance in electronics and
solar designs.
Quantum Materials plans to integrate the
LANL thick-shell technology into its
quantum dot product line. The Company’s
automated process is capable of
manufacturing industrial-scale quantities
while maintaining tight uniformity and makes
possible the reliable, economical production
of thick-shell tetrapod quantum dots having
the exact characteristics necessary for
specific applications.
Stephen B. Squires, Quantum Materials CEO
and Founder believes that the number of
quantum dot performance improvements
afforded by adding thick-shell technology to
their Tetrapod Quantum Dots will set them
significantly ahead of their competition.
The ability to manufacture uniform industrial-
scale quantities of quantum dots engineered
for optimal application-specific performance
parameters will expedite acceptance of
these new technologies by display and
lighting manufacturers.
Combining LANL thick-shelling abilities with
QMC’s tetrapod quantum dots’ properties of
high uniformity, and narrow emission (higher
color purity) is expected to be revolutionary
in affecting quantum dot lifetime, quality
of performance, enhancing of stability,
and color rendering.
Whats Next for Mid-Power LEDs in Lighting Applications
MP LEDs are uniquely suited for linear and distributed lighting applications such as LED
tube lighting and troffers. MP LEDs are now gaining popularity for deployment in other
lighting applications with specific needs which can be met when designed with the end
application in mind. An example would be a high efficacy MP LED with good quality of light
(min 90 CRI) for use in retail shops. K. Lee, M. Chang and D. Kane from Philips Lumileds
will take a close look at MP LEDs, the factors that have led to their use in lighting applications
and what we can expect in terms of their proposition and usage in the future.

LED professional: First of all, wed like
to say thank you for talking to us about
the latest trends in the area of
solid-state-lighting within the scope of
the Tech-Talks BREGENZ. To begin,
could you tell us a little about the
history of the CIE and what your duties
are as General Secretary?
Martina Paul: The CIE is actually a
very old organization. Its predecessor
was founded on the occasion of the
World Expo in Paris in the year 1900.
The gas industry called about 500
engineers and scientists together to
standardize the photometric properties
of street lamps. At that time,
street lamps were run on gas. At the
beginning, the CIE was called the
Commission de Photometrie and then
in 1913 it changed its name to
Commission Internationale de
l’Eclairage or the International
Commission on Illumination in English.
Through disrupting technologies like
solid-state lighting and regulatory
interventions to promote energy
efficiency, the stakeholders have also
changed. There are new groups of
stakeholders which did not have
anything to do with lighting in the past,
such as the semiconductor industry.
I personally come from the area of
organizational development and
change management. I have always
worked in international organizations
within very complex environments.
My main competence lies in being
able to reduce complexities and to
find solutions for complex problems
for various players on a global
context. Light is a very challenging
subject and at the same time,
inspiring, especially when leading
this organization as its CEO through
the technological changes.
LED professional: Can you tell us a
little bit more about the organizational
structure of CIE?
Martina Paul: The CIE not only covers
the subjects of light and lighting, light
quality and measurement and the
description thereof, the metrics,
but color is also a key topic. One of the
first crucial standards that the CIE
published was in 1931: the so-called
color matching functions, which was
the basis for how the human eye sees
color. The CIE has a very broad
spectrum that has expanded to the
areas of photobiology, photochemistry
as well as image technologies. Like all
standardization and scientific
organizations, the CIE is based on
national committees. Right now there
are 51 committees from all over the
world. These committees must
organize the stakeholders that work
with light and lighting in their respective
countries. It happens quite often that
the CIE committees are consolidated
on a national level and are identical to
the national lighting organizations.
We still differentiate between national
full members and industrial, supportive
members who, together, finance
the CIE. The direct work is done in
so-called Technical Committees
which are part of the divisions.
LED professional: You mentioned
scientific work – which is the basis for
every regulation. Is the scientific work
carried out in Technical Committees
or is it “out-sourced”?
Martina Paul: Since the laboratories
are CIE members, it is actually the
same. We are currently working on
defining a new Color Fidelity Index.
Division 1 is responsible for color and
perception. Right now we are at the
point where a lot of experiments are
carried out. Ten laboratories from all
over the world have joined together in
order to be able to carry out the final
experiments. Once the experiments
have been evaluated, they will be
published by CIE as a technical report.
The scientific work is carried out in the
laboratories and the evaluation and
publication is carried out through CIE.
The transition from a technical report
to a standard is done through formal
polling steps. Most of the time, the
technical report is the groundwork that
is sent to the national committee to be
commented on. It sometimes takes
months of negotiations to integrate all
of the changes asked for by the
interest groups.
LED professional: Who decides
which technical reports become
standards, and how are the technical
reports evaluated as suitable?
Martina Paul: Technical reports
present the underpinning science
and evidence, the groundwork, and
might suggest the basis of a standard
on that evidence. In the past, technical
reports would be assessed within the
community while a resulting standard
was being formulated. Today the pace
of change is so swift that this method
is challenged and we have something
of a conflict between scientific certainty
and the speed of changing technology
and demand for new standards.
LED professional: Light is often
perceived subjectively or culturally and
has cultural preferences. If you want to
make something into a standard,
should you take these different aspects
into account? For example, light color
has very different traditions. How do
you find a common denominator so
that a general regulation, norm or
standard can be created?
With the rise of LEDs as the future lighting technology, the relatively stable lighting
industry faces many changes and challenges. One of the main challenges is the ever
increasing speed of transitions, something already seen in the semiconductor business.
Standardization organizations are facing similar challenges. On the one hand they should
define standards that will last as long as possible and on the other hand the standards
need to be as clear and precise as possible. Martina Paul, Secretary General of the most
important standardization body, the International Commission on Illumination (CIE) was
invited to the Tech-Talks BREGENZ to discuss these topics.
Issue 43 2014© 2014 LUGER RESEARCH e.U.
Martina Paul: Some things cannot
be made into a norm. A guideline
consensus is needed to know what
should be normed and what shouldn’t.
There are also norms that are only
valid in, for example, Europe, the USA
or China. And it should stay like that.
Not everything is suitable for
international standardization. It is
necessary to have guidelines for global
standardization and the CIE only works
on global standardization tasks.
LED professional: Besides the CIE
standards there are also the ISO
standards. Can you explain the
synergies and differences between
what the CIE and the ISO do?
Martina Paul: The International
Organization for Standardization or ISO
is an affiliation of national standardization
organizations like the DIN in Germany
or the ANSI in the USA and is made up
of over 200 member organizations.
The CIE was officially recognized
by the ISO as an international
standardization organization in 1986.
Out of four organizations worldwide that
have this status, the CIE was the first
one to receive it. This status means that
the CIE has the right to draft standards
and position them with ISO.
LED professional: To what extent are
the ISO technical committees involved
in the development procedures of the
CIE standards?
Martina Paul: Up until now,
the CIE has made all of the basic and
fundamental standards including the
application-oriented standards.
A disadvantage of the CIE is that it
is only partly connected to national
standardization bodies, namely only
where there are national CIE
organizations who are connected.
The ISO technical committee was
founded in order to increase the
intake of new standards into the
national standards inventories.
An agreement was made that the ISO
committee would run complementarily
to the CIE which means that the
scientific part and the fundamental and
basics in the domain would remain
with the CIE.
An example would be the current
topic of “Energy Performance of
Buildings”. The way basic metrics like
daytime light parameters is described
is very important. There is a work
group in the ISO technical committee
that also works with the CIE and the
balloting process runs directly through
the involvement of the national
standardization organizations.
In this way the organization path has
been changed but at the same time it
has been made more transparent
and sustainable.
LED professional: Could you tell us a
little more about your job as General
Secretary of the CIE and what the
current tasks in the ISO TC are?
Martina Paul: I have been the General
Secretary at the CIE for 7 years now.
My job, together with the President,
is to represent the CIE to the public.
The General Secretary is the only paid
political function. All of the other
people do their work on a voluntary
basis in addition to their day jobs.
Most of them have a certain amount
of time allocated to them by their
employers for the standardization
and/or scientific work for international
organizations. But in the end,
it is volunteer work. The DIN is a driving
force behind the ISO committee and
holds the administrative office, which in
turn means that they hold the right to
suggest who will be the chairperson.
This means that since I am the General
Secretary of CIE I was appointted by
DIN. My duties are not technical in
nature but rather our task as chair-
people is to create a consensus and
to make sure that there are properly
agreed, consensus-based documents
that can be adopted.
LED professional: Apart from the
interesting organizational topic,
let’s take a look at the contents.
What changes has solid-state-lighting
brought to the CIE and what topics
are classed as important and have
been addressed?
Martina Paul: Naturally, LED and
OLED technologies can be labeled as
disruptive technologies. The original
light sources manufacturers are not the
same ones that produce LEDs or
semiconductors. Industries that we
had no contact with at all in the past
have suddenly become important
players in this market and these
players don’t have a lot of experience
with light. Because of this, a brand new
value chain has developed and the
market is still not completely
reassessed. Coordination of the
stakeholders has been an important
task in the recent past and this phase
is pretty much completed as far as
I can see.
Content wise, a lot of changes have
had to be made. Certain fundamentals
have been written in stone and don’t
have anything to do with light sources.
Some things like the area of
colometrics only changes a little.
But the LED has other photometric
characteristics with various colors and/
or spectrums and is a point light
source. The human eye perceives the
color of the LED light source differently
than it does with a traditional light
source. This means that the traditional
color and glare metrics aren’t 100%
correct any more. There is a technical
committee – Division 3 – that is
working on the subject of “New
Evaluation of Glare from LEDs”.
LED professional: Will this new
knowledge be added to the standards
or will the standards be “updated”?
Can you give us an example of what
subjects currently have a high profile?
Martina Paul: The standards in
question are being reviewed and might
be updated if so requested. There is a
technical committee that is concerned
with the subject of OLEDs and we are
already working on this technology.
Division 2 – Photometry – will also start
concentrating more on the subject
of OLEDs.
We have also published a new report –
Nr. 206 – titled “The Effect of Spectral
Power Distribution on Lighting for
Urban and Pedestrian Areas”.
This report shows that the human eye
perceives light from certain LEDs as
brighter than traditional light sources,
which means it can be dimmed and
energy is saved. The boundaries are
naturally the deciding factor and this is
where measurement is relevant.
These are the areas where classic
metrics don’t work anymore and
new metrics are necessary.
LED professional: How long
do you think it will take for the
reprocessing of the content
process of change and the
subject of SSL? Can it be
Martina Paul: There are
discussions going on right
now and I will be holding a
workshop on the subject of
“Standardization and the Art of
Imperfection” soon. This means
that we should consider
standardization more as a work
in progress. Perhaps it would be
a good idea if we agreed on one
terminology that simply means
that right now the descriptions
are snapshots and that work will
continue. This is why I don’t feel I
can commit to a time. My theory
is that standardization as
conventions should be seen
differently today, namely as
snapshots for a time period of at
least three years. It should be
clear in the standard where there
is room for development.
You asked before about how we
present flexibility. This is the
exact challenge that we have,
where we quote bandwidths or
where we have to put certain
areas “under construction”.
We have to define it in terms of
scientific organization where we
make it easy to identify and
define knowledge and
unawareness. One has to
abandon the definition of the
forever-valid standards or
scientific findings. This change
process that we are now going
through is an interaction of
technological changes through
SSL and globalization and the
new orientation of the market
structures in general.
LED professional: We see the
changes in perception just as
you have described. What other
aspects are there due to or
through the initiation of SSL
Martina Paul: The main thing is
measurement techniques and the
measurement of LEDs because
they have other characteristics
and are also different in regards
to spectral characteristics.
In addition, metrology has
changed and as a result the
concept of measurement
uncertainty is a concept that is
worked with more and more.
Both private and state labs are,
in many cases, not sure as to
what measurement uncertainty
means. In the last LED
professional Review you had an
article by two CIE experts about
that. Marketing observation is
carried out by being able to
compare products and this is
achieved by being able to
compare measurement methods.
The CIE is now working on a
measurement standard and we
have come quite a long way with it.
The draft for a measurement
standard is already being polled.
Just as an aside, I’d like to tell you
the difference between regulators
and standardizers. The CIE
doesn’t make regulations, but
rather, standards. Standards are
voluntary whereby regulations are
mandatory and are stipulated by
the lawmakers. Of course,
the state can link certain
standards to market initiation but
the standards are not legal
regulations. The International
Energy Agency (IEA) is a classic
regulator agency that is manned
by governments. It has its own
Annex 4E that concerns itself with
testing and test methods.
The CIE has an agreement with
the IEA, namely that the
regulators will promote and
implement CIE measurement
LED professional: How far
along is the standardization of
the Color Fidelity Index?
Martina Paul: Color rendering
has to be newly defined because
LEDs have different spectral
characteristics. For this reason,
Division 1 is very busy developing
this CFI because the CRI
Issue 43 2014 © 2014 LUGER RESEARCH e.U.
developed by the CIE is no longer
applicable in some cases.
As I mentioned earlier, we are in the
last measurement round; measuring
samples and evaluating the results.
This experimental round is being
managed by a Japanese university
professor. The CFI is the most
important and most needed new
definition in the industry. We surveyed
all of the divisions and found out what
they think are the necessary standards
and which technology reports are
necessary and then passed on the
results to the industry. It turned out
that internal and external ideas were
congruent, which I, as General
Secretary, find as a good sign.
Through this there is a type of
prioritization and standardization plan.
CFI is at the very top of that list.
We estimate that it will take another
one and half to two years before
the CFI becomes a standard.
LED professional: Today LEDs can
be run on a pulsed mode or digital
information is conveyed through the
light. Because of this there are
sometimes totally dark phases in the
light, which leads to the question of
how this will affect humans. Is this
also part of the CIE’s range of duties?
Martina Paul: Visual aspects of
time-modulated lighting systems are
presently discussed in TC1-83 and
a report will soon be published.
In addition there might be non-visual
effects of modulated lights and this
subject has been placed with
Division 6 – Photobiology.
This division is also working on
the question of how blue lights
affect people. Very complicated and
elaborate studies are necessary for
Division 1 and Division 6 because
people have to be involved as
test subjects.
LED professional: You are also
chairperson of the ISO TC 274. Can
you give us some insight into the
goals and tasks of this TC?
Martina Paul: The TC 274 is a
technical committee of ISO and is in
the initialization phase. This TC will,
for the most part, cover the application
specific part of the norms. The idea is
that, next to the basic fundamental
standards, there will be additional
standards for the application in specific
lighting situations like interior lighting,
exterior lighting, road lighting, tunnel
lighting and so on. These will be
worked on by the TC 274.
LED professional: Let’s take a look
at current trends in the area of energy
saving. What is the CIE’s position in
the areas of Smart Lighting or the use
of day lighting?
Martina Paul: The subject of day
lighting is, of course, very important
and is being worked on by the CIE.
As a basis there is, for example,
the sky definition, the day light
definition like the CIE “General Sky”
which is an international CIE standard.
This subject has come to the forefront
Martina Paul again through the “Energy Performance
of Buildings”. The subject of Smart
Lighting, where it concerns the product
standards in the area of electronics,
is covered by the IEC. To differentiate,
it must be clarified that the CIE
concentrates on the application and
fundamentals whereby the IEC
concentrates on the parameters and
safety, etc. of real products. There is
the famous safety norm: IEC 62471.
Photobiological Safety of Lamps.
This document was initially a CIE Norm –
Standard 009 that is now a joint
standard of both organizations.
LED professional: You need a
connection to real life – the industry –
to do your work. How do you make
these connections?
Martina Paul: The Global Lighting
Association (GLA) was originally
called the Global Lighting Forum and
covered the national/regional lighting
associations globally. Over the years,
association structures were created
and commitments were formed and
now it is the GLA with its headquarters
in Brussels. The GLA is associated
with LightingEurope, the new
organization structure in Europe,
and can be understood as the voice
of the international lighting industry.
The CIE and GLA signed a
Memorandum of Understanding
last year. This cooperation is
sustainable, efficient and built on
a broad foundation.
LED professional: Thank you for
participating in the Tech-Talks
BREGENZ. To close, what is the CIE
planning for the Year of Light 2015?
Martina Paul: The UNO General
Assembly has declared 2015 to be a
worldwide Year of Light. The CIE plans
to have a global Open Lab Day that
should take place in May 2015 and our
51 National Committees which span
all continents will contribute with a
variety of events.
I’m looking forward to coming back to
Bregenz for the LpS 2014 at the end of
September. Thank you.

Light + Building Review:
Trends, Innovations and
Technological Tidbits
The worlds largest bi-annual lighting exhibition can be summarized with the words “Its all LED.
But LEDs themselves were not the only things there. There were OLEDs and smart controls as well.
The out-and-out explosion of LED products and LED-related products makes it impossible to cover
everything even if focusing on the component level. Based on a vast amount of impressions,
Arno Grabher-Meyer from LED professional selected some of the highlights to illustrate the latest trends.
Light + Building 2014 (L+B 2014)
not only set a new exhibitor and
exhibition space record with
2,458 exhibitors, but also
announced a new attendance
record with over 210,000 visitors
from 161 countries. Traditionally,
the best represented visitor
nations after Germany were Italy,
the Netherlands, France, China
and Austria. There were also
significant increases from
numerous expanding markets,
such as Russia, South Africa,
Mexico, Turkey and Indonesia.
Particularly striking was the return
of visitors from Southern Europe
with high double-digit rates of
growth characterizing visitor
numbers not only from Spain and
Portugal but also Greece. While
the spotlight on energy efficiency
and intelligent building
management anticipated a
foreseeable trend some other
trends in the lighting area were
probably less obvious but
certainly not less important.
LED Light Sources –
Applicability, Quality &
Those that expected the speed of
LED efficiency improvements to
approach the physical limits and slow
down were completely wrong. Most
manufacturers quietly stated that the
practical value of efficiency increases
in regards to energy savings may not
be as important as it was one or two
years ago. This was due to the simple
fact that in 2012 an increase of 20 lm/W
meant an increase of 20% to 30%.
Today, in many cases it is only
10% to 15%. In 2012 the latest, best
publicized and demonstrated
components offered 80 to 120 lm/W
while today some products are
proclaimed to offer up to 200 lm/W
both in hot systems and system levels.
When comparing incandescent lamps
to LEDs in 2012, the energy saving
potential was approximately 80%.
In 2014 it is close to 90%. An increase
of only 10% may not seem like much
when regarding energy cost savings,
but this increase means that efficacy
has doubled, and LED manufacturers
have emphasized that while being a
good marketing argument, there is
still much more. It is true value for
packagers, module and luminaire
manufacturers. Every single lumen per
watt efficacy gain eases design
options, reduces heat issues and in
the end, lowers manufacturing costs.
For this reason it seemed that every
LED manufacturer at L+B advertised
efficacy improvements for their LEDs.
For example, Cree announced a new
lab record of 303 lm/W just before
Light + Building, and Osram
demonstrated the world’s most
efficient LED replacement tube
prototype with a system efficiency
of 205 lm/W that could become
available by the end of next year.
As a result of this rapid development,
a general trend of the tier one LED
manufacturers followed. The increased
efficiency allows for tighter packaging
of LEDs without sacrificing thermal
properties too much. They introduced
so-called high lumen density array
LEDs of different dimensions. This
trend more or less picked up pace last
autumn at the LpS 2013 with the
introduction of Crees CXA1520 LED.
It culminated at this year’s Light +
Building with an extension of Cree’s
product range, the introduction of
Osram’s Soleriq P 9 and products
from Samsung, Sharp, Xicato,
Luminus, Bridgelux, Lumileds or
Lextar, just to name a few.
These efficacy improvements lead
towards more cost effective Mid
Power LEDs and a tendency towards
Low Power LEDs. In addition to
Issue 43 2014© 2014 LUGER RESEARCH e.U.
improved packaging technologies that
reduce the packaging costs,
the implementation of these products
in different applications is now an
affordable solution. Especially for area
lighting, products based on these LED
types may simplify the optical design
to reduce glare. How intense a
company exercises this trend is
definitely a question of their strategy.
LG Innotek even added primary micro
optics with batwing distribution to the
tiny 3030 package to support area
lighting better. This new LED allows
sleeker luminaire design with fewer
LEDs per module and increased
overall efficiency at lower costs and
maintained emission uniformity
compared to standard LEDs without
optics. Mass production of the
3030IOL is expected in October
of this year.
Minimized or no packaging is
another trend. Improvements of
manufacturers of flip-chip technology
and phosphor molding processes
led to the introduction of LEDs with
well-reduced package dimensions as
well as package-free or substrate-free
(white) LEDs. Manufacturers like
Samsung, Toshiba, Lextar, ProLight
Opto and TSMC demonstrated
increasingly smaller package sizes
on the mid-power and high power LED
level while providing sufficient current
capability and luminous flux. In this
category, Toshibas GaN-on-Si based
LEDs are the industry’s smallest white
mid power LEDs. With a package size
of just 0.65 x 0.65 mm, they achieve a
luminous efficacy of 130 lm/W and
superior heat dissipation that allows
them to be driven with a forward
current up to 180 mA.
Not really new, but something that is
continuously increasing, is the trend
of offering CCT and color tunable
LED packages. The strategies and
philosophies of the different
companies vary between following
the Planckian locus accurate using
at least 3 different LEDs or simply
shifting power between two LED
types of different CCT. This trend is
heavily supported by another very
recent development that will be
discussed as an example in a
related application.

Issue 43 2014 © 2014 LUGER RESEARCH e.U.
There was an article in the LED
professional Review (LpR 40) -
entitled “HD-Retina LED Technology,
Light Quality Beyond CRI” -
This topic was found everywhere at
the L+B show. Almost every LED
manufacturer presented a series or
type of LED with very similar
properties. By setting the color to a
certain point below the Planckian
locus, the typical yellowish-green tint
of white objects that are illuminated
by phosphor converted white LEDs
was eliminated. A thoroughly mixed
phosphor composition allows
saturated colors and neutral, pure
white at the same time. Philips calls
this technology “Crisp” white LED
technology, Xicato the “Vibrant”
series, and Citizen calls it simply
“Below Black Body Locus” (BBBL),
while other companies have their
own fancy names for these products.
Some of them even do not define a
CCT value. Bridgelux also offers
similar products to their clients, for
instance for the HD-Retina lights.
It is hardly surprising that module
manufacturers, like Tridonic with
their “FASHION” module series or
“Tunable White” LLE series, follow
the same trends with very similar
approaches regarding CCT, CRI,
color tuning or lumen density.
But module manufacturers also
utilized their design freedom to show
additional concepts, initiating trends.
Approaches for simplifying
manufacturing and adding features
and electronics were the most
interesting ones. But there were also
attempts and different interpretations
of the Zhaga standards that were
meant to satisfy the specification of
the standard while adding additional
features like mounting options.
BJB not only demonstrated their
robotic lines for manufacturing
luminaires, they also had their own
newly designed socketed module on
display that simplifies mounting and
is available in a DC and AC version.
Bridgelux also launched another
product in the module business.
Following the introduction of their
Vero in 2012, they presented the

Outdoor Lighting Module (OLM)
Series this year. Different power
ratings with related efficacy and
different photometric properties
were designed to satisfy different
applications and requirements.
Bridgelux aims to help luminaire
manufacturers by reducing time to
market, R&D costs, time saving
manufacturing and the elimination
of some technical uncertainties.
Xicato started a true offensive of
product announcements
immediately before Light + Building.
Two product announcements
followed the general trend of
increasing lumen density and
efficiency. With the introduction of
the XTM series, Xicato now offers
Zhaga compatibility if required.
But the most advanced and most
interesting new product is their XIM
series. The concept allows Xicato
to follow the different demands of
their customers to implement
sensors and other features while
providing similar photometric
properties like all other Xicato
modules of the standard and
vibrant series. They are currently
offering a basic set of surveillance
and controls options for the module
using their own integrated μC
based driver. A cost effective simple
48 V AC/DC power supply can
power numerous modules which
can be controlled using DALI or
1-10 V dimming. That simplifies
system design and lowers costs.
The concept allows a clear control
of all parameters to determine
lifetime and integrate full electrical
and temperature protection.
The vision of the developers for
future product generations is to
eliminate multiple visible sensors in
a space and to integrate all of them
in the module that shares the
gained information with other
building automation and
surveillance systems. This visionary
approach anticipates the
predictions of the “Lighting Controls
Report” which is also part of this
LpR issue. Beyond these properties
the product was very impressive
with its smooth flicker-free low level
dimming to 0.1%.

Drivers, Controls & Sensors –
Wireless and Intelligence
For years now, different catchphrases
have been around and different
concepts have been presented on
the market, from LiFi to power line
and wireless. For this reason,
people were hoping for new trials.
When observing the activities of
The Connected Lighting Alliance
establishing the ZigBee Light Link for
the residential market, one was
hoping to see a matured wireless
solution or two. The big surprise was
that expectations were exceeded!
This can only mean that developments
had already started before TCLA
started to promote it to the public.
There were also other wireless
systems on display. EnOcean
introduced a 2.4 GHz-based system
that can remotely control the
Philips hue which is the model
for ZigBee LightLink systems.
Actually, practically every system
provider had some kind of wireless
solution that can be controlled with
an app on smartphones and tablets.
But it isn’t only the lighting system
providers that are players in that field;
IT and software specialists also offer
solutions. Currently, the origin of an
app is still relatively easy to determine.
While IT specialists offer apps with
