SemiLEDs Introduces 10W Integrated RGBW LED
LIGHTimes News Staff
November 19, 2013...SemiLEDs Corporation of Chunan, Taiwan, a world leader in vertical LED
technology solutions, has introduced the 10-Watt M63 RGBW integrated 6363 LED.
The 4-channel M63 RGBW reportedly provides over 410 total lumens of combined
red, green, blue and white light output. The LED measures just 6.3mm x 6.3mm
dimensions. The company says that this size makes it ideal for a wide range of
color-changing applications, including entertainment (stage lights, backdrops
and spotlighting), large scale displays, and color-adjustable luminaires for
building façade, wall washing or specialized interior luminaires.
“The M63 RGBW demonstrates a new level of LED product integration
from SemiLEDs,” commented Dr. Ilkan Cokgor, executive VP of sales
and marketing for SemiLEDs. “By combining three colors, plus an
independent phosphor-coated white emitter, onto a single LED package, our
customers will be able to better optimize the optical and thermal properties of
their design, while minimizing the manufacturing complexities of their
luminaires or large scale displays. This integrated approach is enabled by our
well-validated and robust metal vertical LED product portfolio, which can be
reliably driven harder to deliver higher than average lumen density and
increase the lumens per dollar,” Dr. Cokgor added.
According to the company, the integrated package is the first from the
company to combine the company's vertical, white chip, and ceramic packaging
technologies. The multi-color LED opens the door to arrays with cumulative
lumen-densities in excess of 6000 lumens per square inch. The LED's square
footprint reportedly simplifies color mixing and integration with secondary
optics, including narrow beam spotlights. The company notes that the addition
of discrete white to the more conventional RGB color changing LED architecture
enables a broader spectrum and more natural white palette to be projected. The
integrated white led chip reportedly delivers 100 lumens per watt at a
correlated color temperature (CCT) of 6300K to 8000K.
“Every current technology trend is towards higher integration,
both to reduce component count and simplify the final design, and that carries
with it a ripple effect that continues into process engineering and
manufacturing,” continued Dr. Cokgor. “As a result of its
broad technology offering, SemiLEDs is in a somewhat unique position to
reliably deliver these higher levels of integration, as reflected in our new
M63 RGBW. High quality LED manufacturers will continue to differentiate and add
value to the industry by driving increasing integration at both the component
and subsystem level,” he concluded.
Philips Lumileds Debuts Smallest High-Power UV Emitter
LIGHTimes News Staff
November 5, 2013...Philips Lumileds has introduced the Luxeon UV family of LEDs. The company
boasts that the family delivers the very highest system flux densities. Luxeon
UV LEDs come in wavelengths of 380-430nm and are specifically designed for
applications including ultraviolet curing, counterfeit detection, medical,
industrial and specialty lighting. Each 2.2 mm squared LED is provided in
undimmed form, which allows for precise optical control. The company claims
that at one-fifth the size of other high power UV emitters on the market, the
Luxeon UV enables the highest available flux density. The company modeled the
Luxeon UV after the its successful Luxeon Z family.
“The UV LED market has been hampered by limited flux density and a
lack of design flexibility,” said Kurosh Hashemi, Senior Product
Line Manager at Philips Lumileds. “Philips Lumileds addressed these
limitations by introducing a compact, high-power emitter that can be tightly
spaced to deliver the highest flux density to the desired medium. For example,
for curing applications, 395nm emitters enable arrays of up to 38W/cm2 when
driven at 1A.”
The company notes that since the product’s inception, Luxeon UV LEDs
have been optimized for high reliability through: the use of surface mount
assembly instead of wire bonding; a design that enables high-power operation
(up to 1A drive currents); reduced droop and high forward voltage performance;
and multiple binning options.
“We combined the proven advantages of high-flux density and
optical control of the LUXEON Z design with a high performing UV
chip,” said Hashemi. For what the company describes as superior
thermal management, the Luxeon UV utilizes a flip chip assembly, where the chip
is in direct contact with the thermally conductive AlN substrate.
“Customers wanting to utilize air cooling units rather than more
costly water cooling are very excited about the Luxeon UV offering,”

Philips Lumileds Boosts Efficiency and Lumen Density of Luxeon CoB Arrays
LIGHTimes News Staff
October 22, 2013...New Versions of the recently introduced Luxeon chip-on-board arrays from
Philips Lumileds now have 10 percent greater efficacy and a corresponding 10
percent greater maximum lumen output.“Just one quarter into volume
product deliveries, we have increased Luxeon CoB performance by +10%, which
speaks to the rapid rate at which we upgrade the lumen output and efficacy of
our products,” said Eric Senders, Product Line Director at Philips
Philips Lumileds CoB LED arrays reportedly increased their maximum efficacy
from 118 lumens per watt to 130 lm/W. In warm white, the 9 mm array delivers
2200 lm at 100 lm/W and the cool white array delivers 2500 lm at 105 lm/W. The
arrays have a light-emitting surface of 9mm square, 13 mm square or 15 mm
square. The company contends that these options allow designers to use less
expensive optical solutions for ultra-compact luminaires with high center beam
Philips Lumileds also asserts that the metal-core printed circuit board of
the Luxeon CoB substrate provides 4X better heat transfer than competitive
solutions. This reportedly translates to up to 40% smaller heat sinks or
improved reliability of the lighting system when a larger heat sink is used.
“With the recent improvements in performance, Luxeon CoB is an
even better option for a number of general lighting solutions including
outdoor, industrial, retrofit lamps, and of course, spotlights and
downlights,” said Senders. “Our 90 CRI versions have a
typical CRI of 97, which makes them perfect for high Quality of Light
applications. Lumen packages are available with CCTs of 2700 to 5700K and CRIs
of 70, 80 or 90.”
Market for Packaged LEDs for Lighting to Nearly Double in Three Years
SSLDesign News Staff
October 15, 2013...Market research firm IHS Inc. notes that falling prices and rising consumer
acceptance are helping LEDs take over the lighting business. IHS forecasts that
the take over of the lighting business will spurn a 96 percent increase in
revenue for packaged LEDs between 2013 and 2016. Packaged LEDs are LED chips
with a protective cover and contacts for direct soldering. IHS predicts that
global revenue for packaged LEDs used in lighting applications will nearly
double to $7.1 billion in 2016, up from $3.6 billion in 2013.
“As retail prices for LED lamps have fallen, it’s become
more obvious that they are an attractive alternative to conventional light
bulbs, providing long-term savings in energy and replacement costs,”
said Stewart Shinkwin, market analyst, lighting and LEDs, for IHS.
“Because of this, shipments of LED lamps for lighting are set to
increase dramatically in the coming years, rising to 2.4 billion units in 2016,
up from 520 million in 2013. The rapid expansion of the lighting market will
come as a major boon to suppliers of packaged LEDs, which are seeking the next
growth opportunity following the slowdown of the backlighting
IHS points out that previously, rapid growth in the packaged LED market was
driven by LCD display backlighting in applications such as mobile phones,
notebooks and TVs. However, according to IHS, the majority of these display
applications have completed their transition to LED technology. Therefore, IHS
forecasts that while LED demand for these products remains stable, annual unit
growth largely is limited to single-digit percentages.
The lighting market will provide the next wave of growth for packaged LEDs,
according to IHS. IHS figures reveal that the lighting sector became the
largest end application for the packaged LED market in 2012, overtaking the TV
backlighting market. The LED backlighting market is saturated, IHS says, and
this market saturation has resulted several leading suppliers of packaged LEDs
to shift their focus and development resources toward the lighting industry.
Penetration of LEDs into the lighting market is set to increase, IHS
asserts, because of decreasing LED lamp retail prices and better consumer
understanding of total cost of ownership of LED lighting and their saving
potential. IHS says that intensified competition among LED lamp makers will
help to drive down the prices for packaged LEDs. In about five years IHS
predicts that the average selling price for packaged LEDs will be less than
half of its current prices. The lower prices will result reduce the consumer
payback period for LED lighting. While this will increase adoption, it will
also result in declining profit margins for suppliers.
While LED lamp penetration is already significant in a number of lighting
applications such as the retail and hospitality sectors, IHS forecasts that the
residential sector will provide the largest opportunity for packaged LEDs.
Packaged LED revenue in the residential sector will approximately triple to
nearly $2.7 billion in 2016, up from an estimated $850 million in 2013, IHS
says. Therefore, IHS says that manufacturers that carve out share early on in
this market could garner significant returns during the market boom.
Seoul Semiconductor to Sell Acrich2 AC LED Modules in Kit Form
SSLDesign News Staff
October 8, 2013...Seoul Semiconductor, announced the globally availability of an Acrich kit.
The company says that the Acrich kit is for customers trying to meet the
special design requests of global lighting manufacturers. The kits consist of
Seoul Semiconductors' Acrich Multi-Junction Technology (MJT) LEDs along with
the Acrich Integrated Circuit (AIC) power controller device. Seoul
semiconductor released the Acrich kit because of a surge in requests from
customers who want to make their own form factors. Seoul notes that most of its
mid- to large-sized lighting customers have their own SMT lines and the ability
to source and handle discrete parts; therefore, they prefer to purchase a parts
kit rather than a module. The company asserts that the kit gives designers
maximum flexibility in designing AC LED modules for their unique fixture
Seoul Semiconductor says that the Acrich kit has a high power factor, low
EMI and low THD and can be driven directly from AC line voltages of 100 to 277
volts, and the AIC is available with a smart dimming function. The company
recently announced a 10W, 140 lm/W downlight module using the Acrich2. The
downlight replaced the AC/DC converter (or ballast or driver) with the Acrich
Marten Willemsen, Vice President of Marketing for Seoul Semiconductor, said,
“We have seen a surge of interest in Acrich recently due to its
performance improvement. The new sales strategy to offer Acrich kits is in
direct response to the requests from customers.” He added,
“For broadening our targets and serving the broader global lighting
market, Seoul Semiconductor is now promoting our products through Acrich kit
sales at new price points.”
Bridgelux Introduces V Series LED Arrays for sub 1000 Lumen Commercial and Residential Markets
LIGHTimes News Staff
September 25, 2013...Livermore, California-based Bridgelux Inc., introduced a new line of
Chip-on-Board LED array products called the Bridgelux® V Series™.
According to the company, these cost-effective light engines extend the
technology and performance of the company's Vero™ line. Bridgelux says
that they feature high flux density in small source size packages and are well
suited for sub 1000 lumen commercial and residential lighting markets where
tight beam control and high quality light matter.
The Bridgelux V Series LED arrays were developed to bring Bridgelux light
source technology to sub 1000 lumen applications such as PAR and MR-16 lamps,
small aperture down lights, landscape spots, security lights, track lights,
spots, and accent lights. The V Series arrays will initially come in two light
engine sizes (V6 andV8). They will have with multiple electrical
configurations, CCT and CRI combinations, for greater design-in flexibility and
energy-efficiencies. The LEDs feature ANSI compliant 3-step binning.
The company says that the light engines can be driven at twice the nominal
current.`'l Bridgelux notes that this ability to be driven at higher current
translates greater design flexibility and superior lumen per dollar
performance. The V Series LED arrays are supported by a variety of existing and
new mechanical holders, optics and drivers from a variety of established
partners. Bridgelux claims that this interchangeability brings down overall
sourcing and installation costs for lower lumen applications.
The company says that the V Series arrays feature a low thermal resistance
and an electrically isolated thermal path for simplified thermal management.
They also support Energy Star and various rebate programs with more than 7,000
hours of LM80 test data and R9 values that exceed California Energy Commission
requirements for luminaires and lamps. Like all Bridgelux array products, the V
Series comes with a 5-year limited warranty.
“We leveraged many technological advances from our industry
leading Vero LED Array Series to bring our high quality light engine technology
to the V Series for lower power, cost sensitive applications,” said
Max Hong, chief sales and marketing officer of Bridgelux. “These
small LED packages are well suited for low lumen applications and will help
accelerate the migration from traditional light sources (such as incandescent
and halogen) to cleaner, more efficient solid state lighting.”
The new Bridgelux V Series will be commercially available in early October
with pre-orders for this new product being accepted now.
