Cree Makes Extreme High Power XHP LEDs Commercially Available
LIGHTimes News Staff
December 19, 2014...Durham, North Carolina-based Cree, Inc. announced the commercial
availability of XLamp® Extreme High Power (XHP) LEDs. The company introduced
the XHP LEDs in October. The company claims that the XHP LEDs are a new class
of LEDs that enable a system cost reduction of up to 40 percent for lighting
applications. The XLamp XHP50 and XHP70 LEDs, which are powered by Cree’s
SC5 Technology™ Platform, boast twice the lumen output and improved
reliability compared to previous LEDs of the same size.
The XLamp XHP50 and XHP70 LEDs deliver up to 2546 lumens at 19 watts from a
5.0 x 5.0 mm package and up to 4022 lumens at 32 watts from a 7.0 x 7.0 mm
package, respectively. Improvements in the light conversion process has
reportedly helped Cree reduce LED-to-LED color variations. XHP LEDs come in
2-step and 3-step EasyWhite® bins for 3500K through 2700K in 80 and 90 CRI. The
XHP LEDs allow manufacturers to choose either 6 V or 12 V configurations from
the same LED through the solder pad design on the circuit board.
“Cree’s new technology is game-changing compared to the
incremental advances of other LED suppliers. The breakthrough performance of
XHP LEDs enables both new design possibilities and dramatically lower system
costs for LED lighting,” said Nate Heiking, Advanced Lighting
product manager, Kenall Lighting. “We’re excited that
Cree’s new class of Extreme High Power LEDs will accelerate customer
adoption of LED lighting.”
Cree contends that its XHP LEDs allow lighting manufacturers to dramatically
reduce the size and cost of their lighting systems using fewer, more reliable
LEDs to achieve the same brightness. According to Cree, designs with XHP LEDs
enable new lighting designs that require smaller housing, a smaller printed
circuit board, and fewer optics. Cree asserts that XHP LEDs also achieve longer
lifetimes even at higher operating temperatures and currents than previous LED
technology, allowing a smaller sink and reducing cost without impacting the
Cree says other cost reductions on a system level are possible with its XHP
LEDs. In roadway and outdoor area lighting, XHP LEDs enable a radically smaller
and lighter luminaire that requires a less expensive pole. According to Cree,
similar dramatic cost savings compared to existing solutions are possible in a
wide range of lighting applications, including stadium, track, and high bay.
“Cree’s new Extreme High Power LEDs demonstrate our belief
that high-power LEDs are what will drive the industry towards the next
generation of lighting system designs,” said Dave Emerson, vice
president and general manager for Cree LEDs. “Leveraging our
groundbreaking SC5 Technology™ Platform, Cree’s new XHP LEDs
deliver not only exceptional performance, but also enable up to 40 percent
system level cost reductions.”
Samples of both XLamp XHP50 and XHP70 are available now, and production
quantities are available with standard lead times.
Plessey Achieves 120 lm/W with GaN-on-Si LEDs in Lab and its GaN-on-Si LEDs to Power 8point3's Linear Lighting Products
LIGHTimes News Staff
November 20, 2014...Plessey Semiconductor of Plymouth, UK reports that the company has agreed to
supply its gallium nitride on silicon MaGIC (Manufactured on GaN-on-Si I/C)
high-brightness LEDs to UK-based LED luminaire producer 8point3 Ltd. 8point3
plans to use the Plessey LEDs in its new Sabre Architectural range of LED
linear lighting products, which will be officially labeled ‘Made in
Britain'. Plessey asserts that that recent performance improvements in its
MaGIC LEDs have made them competitive with any LED technology.
In related news, Plessey announced that its GaN-on-Si MaGIC high-brightness
LED technology has achieved light output of 120 lumens per watt with over 50%
light output efficiency.
8point3's Sabre Architectural luminaires employ remote phosphor with a
unique light emission design that provides what the company claims to be high
system efficiencies and economic life. The Sabre Architectural luminaires come
in a wide range of color temperatures, and are said to deliver a uniform and
diffuse luminance and appearance without reflections or pixilation. The Sabre
Architectural luminaires offer lighting for high lumen areas.
“A technology agreement has also been reached, whereby Plessey
will design bespoke LED solutions in the UK to complement 8point3’s
ongoing lighting projects,” said Mark Pinnock, Plessey’s
regional sales manager for Northern Europe and account manager for 8point3.
Plessey’s range of products for lighting applications is being
showcased at LuxLive (the UK’s biggest lighting show) at ExCel London
Plessey hopes to achieve even greater lm/Watt efficiency soon. Plessey chief
technology officer Keith Strickland commented, “Whilst 120 lumens per
watt for an LED may be considered ‘acceptable’ to industry, we must
remember that we have doubled our LED light output in the past six
“I see no reason why we cannot reach state-of-the-art in LED die
output performance within the next six months. This current process technology
will become the base for our Application Specific LEDs, the ASLED that bridges
the gap between the LED component suppliers and the solid-state lighting
fixture designers and OEMs,” Strickland continued.
“The combination of expertise and a sustained period of light
output performance improvement in the core LED material is due to our holistic
approach to LED development - our in-house experts in epitaxy growth, process
development and die design all working together,” said operations
director Mike Snaith. “This way of working will continue and
strengthen as we drive towards the next generation of higher-efficiency,
silicon-based integrated LED solutions and away from discrete, plastic-packaged
Osram Opto Semiconductors Adds P 13 to its Soleriq P Series
LIGHTimes News Staff
November 11, 2014...The new Osram Soleriq P 13, a small LED with a high output and the most
powerful in its series, achieves a brightness level of up to 6800 lumens (lm).
The compact P 13 has a small light-emitting surface measuring just 13.5 mm in
diameter. The LED is reportedly ideal for high-powered spotlights in museums
and shops as well as for high bay lighting. The new Soleriq P 13 LEDs will be
unveiled at the “electronica” trade show in Munich from November 11
to 14 (Hall A3, Booth 107).
The P 13 is available in two versions with different color rendering indexes
(CRI). The CRI 80 LED has a brightness of 4000 lm even at high temperatures
(85° C, 1050 mA) and can be overdriven to provide up to 6800 lm. The entire
package measures just 18 mm x 18 mm x 1.5 mm. The small sized package
facilitates compact and bright lighting solutions for indoor spotlights and
high bay lighting. For spotlight applications demanding high lumen output,
small beam angles, as well as high color quality, the CRI 90 version provides
3300 lm as standard and up to 5600 lm when overdriven.
“Customers could compare the P 13 with the formerly launched Soleriq S
19 due to its similar light output of 4000 to 5000 lm. In fact, the new Soleriq
P 13 has smaller dimensions and is therefore the right choice for more compact
lighting solutions," explained Lim Kok Peng, product manager in marketing for
general lighting at Osram Opto Semiconductors.
With the P13, customers need fewer LEDs to achieve the same light output
compared to other products in the Soleriq P series including the P 9 or the P
6. This saves costs. The company says that the small LES allows a simpler lens
design which costs less and enables more compact lighting solutions. Binning of
the LEDs takes place at 85° C (“hot binning”). The85° C temperature
very closely matches normal operating conditions and enables the brightness and
color values of the LEDs to be precisely determined in line with their
The LED in the Soleriq family are all based on Chip-on-Board technology for
a uniform color and light appearance. The Soleriq family's LES is compatible
with the international Zhaga standard. Furthermore, the accessories tailored to
the Soleriq family such as connectors, optics and drivers are all available on
the market and can be obtained for example via the Osram partner network, LED
Light for you (LLFY).
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.
Luminus launches 1W SMD LED with 170° Emission Angle
LIGHTimes News Staff
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).
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.”
Philips Lumileds Launches New Luxeon CoB LEDs for Spotlights
LIGHTimes News Staff
October 21, 2014...Philips Lumileds has introduced a new compact COB LED array with a small 6.5
mm light-emitting surface that is ideal for spotlights. The small Luxeon CoB
1202 array boasts the highest center beam candle power available. The company
says that its small size makes it perfect for PAR and other directional lamps.
The Luxeon CoB 1202s is also available with Philips Lumileds' CrispWhite
Technology, which the company says produces a high color rendering index and
for rich whites, vibrant reds and other colors.
“The 1202s lifts the bar even higher by producing light output in
a smaller, 6.5 mm LES that was only possible previously in 9 mm LES arrays. In
addition, the 1202s does so with a superior CBCP, delivering 65,000 candelas at
a 10˚ beam angle,” said Ahmed Eweida, product manager for the
Luxeon CoB line.
The company first introduced its CrispWhite Technology for retail lighting
in July 2014.
“The response has been tremendous. Shop owners and their customers
clearly prefer LED lighting with CrispWhite over CDM and halogen,”
said Eric Senders, Product Line Director.
The Luxeon CoB range including the 1202s is available in a very warm, 2200K
version for applications requiring a candlelight-like glow. Philips Lumileds
says lighting designers are using the Luxeon CoB 1202s to produce highly
reliable directional lamps. The company has published a full list of compatible
drivers, optics and holders to help speed the time-to-market for downlights and
Mass Production Begins on Seoul Semiconductor’s Acrich MJT 3030
LIGHTimes News Staff
October 14, 2014...Seoul Semiconductor of Seoul, Korea, made available the Acrich MJT 3030 a
new LED in the company's Acrich MJT product family. The company says it
improves on performance and enables lower system costs. The Acrich MJT 3030
employs Seoul Semiconductor’s high-reliability Acrich MJT technology.
According to Seoul Semiconductor, the MJT 3030 LED offers high lm/$ and
improved performance compared to previous versions in a mid-power package.
This new Acrich series measures 3.0mm x 3.0mm and delivers 103 lumens at
40mA at 22V, 25° C, 3000K. The 3030 LED can be driven to a maximum current of
60mA at high voltage to provide up to 155 lumens. At high voltage and 60 mA it
consumes 1.5 W for over 103 lm/W efficacy. The company designed the LED for
high-lumen applications that require high reliability and low cost. Seoul
points out that Energy Star® qualification is easier with the already completed
6,000 hours LM-80 data of the Acrich MJT 3030 LED.
The LED uses the company’s high voltage architecture and its Acrich
MJT "Multi-Junction chip Technology". The company claims that the Acrich MJT
3030 LED eliminates the tradeoff between size and efficacy. The LED allows
operation in either DC or AC mode, depending on your configuration. The Acrich
IC reportedly eliminates the need for an AC/DC converter and is said to improve
reliability and simplify integration when making lighting fixtures.
The MJT 3030 boasts low THD and a 0.97 power factor both help save energy
and optimize designs. In the DC-mode, according to the company, the low-current
use of the Acrich MJT 3030 can reduce the cost of the power supply and lower
the number of components. The company contends that the Acrich MJT 3030 LED
optimizes performance in both AC and DC configurations.
"The new Acrich MJT 3030 LED combines the improved performance and high
lm/$ with the reliability of the MJT technology enabling lighting manufacturers
to create new innovative solutions to address a wide range of lighting
applications,” said Seoul Semiconductor executive vice president of
lighting sales, Jay Kim.
