October 28, 2014...Luminus Devices Inc based in Billerica, Massachusetts, USA, has launched the
XNOVA Cube, a 1 watt SMD LED with a 170° viewing angle. Luminus contends that
the XNOVA Cube improves system efficacy, reduces cost, and simplifies
Unlike traditional mid-power LEDs, which Luminus says were originally
designed for LCD backlighting, Luminus designed the XNOVA Cube specifically for
illumination applications requiring high quality of light. The small 1.9mm by
1.9mm package has a 170 degree viewing angle, which the company claims is the
widest in the industry. Luminus claims that the XNOVA cube emits more light
than any mid-power LED.
“The XNOVA Cube has opened-up new design options for our customers
in the highly competitive panel lighting, linear and omni-directional lamp
markets,” said Jim Miller, executive VP of sales & marketing.
“They are able to reduce LED count by as much as 30% and at the same
time cut power consumption by 10%, which enables further cost reductions in
drivers, thermal systems, and optical components.”
Luminus Devices is exhibiting its XNOVA illumination product line at the
Hong Kong International Lighting Fair (27-30 October).

Bridgelux Launches New Chip-on-Board LED Arrays with "Human Centric" Design Approach
LIGHTimes News Staff
October 28, 2014...Bridgelux of Livermore, California USA, will debut its new Vero® Decor
Series™ Class A Chip-on-Board (CoB) LED array products at the Hong Kong
International Lighting Fair 2014. The launch of the Decor Series Class A arrays
marks Bridgelux's new "human-centric" approach to product development and color
targeting. The company has started looking at a relatively new metric called
the Gamut Area Index along with the Color Rendering Index.
The Gamut Area Index (GAI) in short measures how light and color appeal to
and are perceived by the human brain. GAI (Gamut Area Index). The gamut area of
a light source is that area enclosed by a polygon within a chromaticity
diagram. The greater the separation among the selected points, the greater the
gamut area. The Gamut Area Index is the difference between the Gamut Area of a
specific light source and a reference light source.
The company contends that while CRI only measures color distortion, the
Gamut Area Index (GAI) measures color saturation and strength to more
accurately reflect the holistic effect of light and how a person will perceive
color. Bridgelux says its Decor Series Class A arrays are engineered at the
optimal GAI and CRI combination based on human perception of light.
The company says it will make the arrays available through global channels
Bridgelux says that the new Decor Series Class A arrays are the first
products to use the full Class A Color specification from the Lighting Research
Center (LRC) at Rensselaer Polytechnic Institute and the Alliance for
Solid-State Illumination Systems and Technologies (ASSIST).
In a long term study with funding from ASSIST, researchers at the LRC
developed what they call, Class A Color. The study examined preferences in
color rendering and how people perceive white light sources along with the
white hue or tint of the light source. Bridgelux reportedly developed prototype
lamps based on the Class A Color spectral requirements for the LRC to use in
"Class A Color has been broadly tested and 'tuned' to ensure the most
pleasing blend of naturalness and vividness based on subjective human
perceptions," said Jean Paul Freyssinier, senior research scientist at the
Lighting Research Center. "A majority (75 percent) of those tested from
around the world agree that Class A Color light sources provide the best color
rendering and optimum saturation levels. It's consistent lighting that won't
Bridgelux insists that Class A colors are inherently more vivid and whites
are their whitest due to a broader spectrum of colors and saturation.
According to Bridgelux, the Decor Series of Class A LED Arrays achieve a
balance of color properties that match how people perceive color to provide
superior color quality. Bridgelux further asserts that the arrays provide a
better return on investment when compared to traditional halogen and ceramic
metal halide bulbs.
Decor Series Class A LEDs boast 30 percent less energy consumption, 70
percent less heat generated, and have a projected lifetime of about 20 times
longer than halogen or metal halide light sources.
In retail settings, Decor Series Class A LED arrays appeal to people's
natural perception of light, helping to drive improved aesthetics, increased
visits, customer purchases, and revenue per square foot.
"The launch of our Decor Series Class A LED arrays is a game changer for
Bridgelux, our customers and the industry," said Brad Bullington, CEO of
Bridgelux. "Light has the power to influence how people behave, what they
purchase, their productivity and their mood. Our new human-centric approach
harnesses that potential to help our customers create custom light experiences
that deliver great aesthetics and a tangible financial impact."
Bridgelux Vero Decor Series Class A arrays will be available in 4000 K and
3000 K CCT. They are designed for applications including high-end retail,
hospitality, museums and commercial spaces.

content that Daktronics Creative Services will produce and deliver. This
content will consist of any mixture of sponsorship messages, crowd prompts,
headshots, game opens and venue announcements at the request of the Saints.
Cree Lowers System Costs with New SC5 Platform and XBH50 LED
LIGHTimes News Staff
October 23, 2014...Cree, Inc. has introduced an LED with the company's SC5 Technology™
Platform. The new platform powers the company's Extreme High Power (XHP) LEDs.
As with their previous LED developments, Cree has begun approaching LEDs not as
the biggest contributor to the cost of a lighting system, but as one of several
contributors including the heatsink and the optics. This approach has lead Cree
to create smaller and brighter LEDs that operate at higher temperatures. The
approach has further lead Cree to develop its XHB50, which the company says
doubles light output and greatly lowers system cost. Cree claims its new class
of LEDs can reduce system costs by up to 40 percent in most lighting
The SC5 platform and the new class of LEDs use the company's silicon carbide
technology. Silicon carbide allows the LEDs to operate at higher temperature
(up to 105 degrees C). At the same time, the new LED has double the light
output of previous iterations with the same efficiency, but in the same
footprint. The LED on silicon carbide that can run at higher temperatures does
not need as large of a heatsink. This translates to lower cost for the
heatsink. Furthermore, the higher output and higher lumen density means that
fewer LEDs are needed for each application, and these take up less PCB space
and have a lower PCB mounting cost (because there are fewer). In turn, this
translates to smaller and less expensive optics.
Cree says its advancements in epitaxial structure and chip architecture go
into the SC5 platform. The XHP50 runs on either 6- or 12-Volts, and has a new
solder pad layout that allows either 6- or 12-volt operation without additional
The first of the new class of LEDs is the XBH50. The XBH50 has an L90 of
50,000 hours. According to Cree, the longer projected lifetime comes from the
LED's ability to operate at up to 105 degrees C. The XHP50 LED delivers up to
2250 lumens at 19 watts from a 5.0x5.0 mm package. Cree contends that at its
maximum current, the XHP50 provides twice the light output of the
industry’s brightest single-die LED, the XLamp XM-L2 LED, at a similar
lumens per watt and without increasing the package footprint.
Chuck Swoboda, Cree chairman and CEO said, “The SC5
Technology™ Platform redefines what is possible in high-power LEDs by
doubling the lumens out of a single LED, giving lighting manufacturers the
flexibility to innovate significantly lower cost systems. This new platform
establishes a new benchmark for LED lumens per wafer, which we believe will
define the long-term success of our industry. This also validates our belief
that high-power LED technology enables the best lighting system designs and a
better lighting experience for end customers.”
“LEDs are no longer the most expensive portion of an LED lighting
system, but they fundamentally determine the overall system performance and
cost,” said Dave Emerson, vice president and general manager for
Cree LEDs. “While other LED manufacturers only promise incrementally
lower LED cost, our new Extreme High Power (XHP) LEDs leveraging the SC5
Technology™ Platform directly address the increased burden that thermal,
mechanical and optical elements now place on total system cost.”
GaN LEDs in Automotive to Reach $1 Billion in 2014, According to IHS
LIGHTimes News Staff
October 23, 2014...The LED Intelligence Service of IHS Technology (IHS) predicts that the
market for GaN packaged LEDs in automotive applications will reach the $1
billion mark this year for the first time. IHS forecasts that industry revenue
will grow 11 percent from $943 million in 2013 to $1.05 billion in 2014. IHS
contends that the growth comes from vehicle exterior applications such as
headlamps and daytime running lights, where LED penetration is still low.
However, IHS notes that the LED value per vehicle can be quite high. Osram,
Nichia and Lumileds are ranked by IHS as the market's leading three suppliers,
and IHS says they are particularly dominant in vehicle exterior
Audi has been a leader in using LEDs in its vehicles (especially in daytime
running lights) since 2008, according to IHS, and many other manufacturers have
followed the trend to using more LEDs in automotive applications. IHS points
out however that many vehicles even at the high end of the market such as the
$100,000 Tesla Model S, still do not use LED headlamps. Moreover, daytime
running lights, cornering lights and indoor ambient lights are only available
as an option rather than as standard. IHS forecasts that LED lighting should
increase in vehicles over the next several years, growing further to $1.3
billion in 2018.
Research Association Produces Prototype LED with 256 Light Points for Adaptive Front Lighting Systems
LIGHTimes News Staff
October 23, 2014...Osram Opto Semiconductors reports that after just one and a half years, the
company and its partners on the µAFS research project have developed a new LED
chip with an unrivaled array of 256 light points (pixels). Previously pixel
systems were based on a large number of individual LEDs. Funding for the
project, a total of seven million euros, comes from the Federal Ministry of
Education and Research as part of its focus on “Integrated
Microphotonics”. The project will run until January 31, 2016.
The project's goal is the development of a new class of energy-efficient LED
headlamps which may then provide the basis for adaptive front lighting systems.
The project intends to design systems that will improve the illumination of the
road ahead through actively adapting the light distribution for the driving and
traffic situation without dazzling other road users.
Experts from Osram Opto Semiconductors, Osram Specialty Lighting, Infineon
Technologies and the Fraunhofer Institute for Reliability and Microintegration
IZM jointly developed a prototype of an LED-based adaptive front lighting
Previous adaptive front lighting systems (AFS) have one pixel corresponding
to one LED component or one chip. However, in this prototype one chip contains
256 pixels, which can all be individually controlled. Osram Opto notes that the
256 pixels per chip prototype is the first step to light sources with more than
1000 pixels. Osram Opto Semiconductors developed the new pixel chip with
defined light patterns in blue and white . According to Osram Opto, the
challenge was to define the light points during chip processing itself and
enable them to be linked directly with the control system. Infineon
Technologies developed the driver chip to directly and individually control the
numerous light points. As the specialist in mounting technology, Fraunhofer IZM
made it possible to couple the light-emitting pixel chip with the controlling
Osram Opto Semiconductors structured the chip surface and attached the
converter for creating white light to complete the prototype. This demonstrator
proves the feasibility of having a particularly high resolution, which is
needed to enable the dynamically adjustable light pattern with a high degree of
precision. Osram Opto Semiconductor contends that the technology in the
prototype will open up special automotive lighting options such as city lights
and bad weather lights.
In one of the next steps, the Osram Specialty Lighting business unit,
intends to transfer the prototype to a light module with electrical, mechanical
and thermal interfaces. Future goals of the project include developing
intelligent control and an appropriate connection to the vehicle bus to ensure
extremely fine control of the light.
µAFS project partners Hella, the automotive lighting specialist, and
Daimler, the car manufacturer, will then take over. Hella is responsible for
the development of the optical system and the thermal management system,
including the design of the complete headlight. Daimler has already contributed
specifications and requirements for the bus connection and optics within the
project, and is responsible for detailed testing of the headlamp and therefore
for the final process.
