LiGHTimes News Staff
May 22, 2013...Cree, Inc. of Durham, North Carolina USA, has announced commercial
availability of XLamp® XP-E2 color LEDs. According to Cree, the new XP-E2 color
LEDs deliver up to 88 percent higher maximum light output compared to
alternative high-power color LEDs. Cree says that this higher maximum light
output enables lighting manufacturers to more cost-effectively address a wide
spectrum of applications such as architectural, vehicle and display lighting.
Cree's new XLamp XP-E2 color LEDs are available in red, red-orange, amber,
green, blue and royal blue.
The new XP-E2 color LEDs are built on Cree’s SC³ Technology™ LED
platform, which uses silicon carbide and combines advances in chip design,
packaging, and phosphors, to provide higher lumens-per-watt and
lumens-per-dollar compared to the original XP-E color LEDs. Cree indicated that
switching to XP-E2 LEDs in existing XP-E LED designs, lowers system costs. The
new XP-E2 color LEDs have the same XP footprint (3.45mm x 3.45mm) and are
optically compatible with the original XP-E LED providing what the company
describes as a drop-in-ready performance enhancement to shorten design cycle
and improve customer time to market.
“We are excited that Cree is offering higher performance color
LEDs in the XP footprint,” said Greg Campbell, executive vice
president and chief technology officer, Lumenpulse. “The brighter
XP-E2 color LEDs enable Lumenpulse to continue to provide innovative,
high-performance LED lighting systems.”
The XP-E2 color LEDs have a maximum drive current of 1A and a viewing angle
of 110 to 135 degrees. The royal blue version of the XLamp XP-E2 color LEDs at
maximum drive current delivers up to 1409 mW. Also at maximum drive current,
the XLamp XP-E2 color LEDs provide up to 109 lumens for blue, 253 lumens for
green, 203 lumens for amber, 193 lumens for red-orange and 155 lumens for red.
All have the 3.45mm x 3.45mm footprint. Cree says samples are available now and
production quantities are available with standard lead times.

Osram Opto Semiconductors Now Offering Duris P 5 mid-power LEDs in Color
LIGHTimes News Staff
April 25, 2013...Osram Opto Semiconductors, has come out with five color new versions of the
Duris P 5 mid-power LEDs. Like the white versions, the new color versions are
said to have high luminous efficacy from a compact form factor. The LEDs are
ideal for architecture lighting and for hotels and restaurants.
The five color versions of Duris P 5 are: “deep blue” (450 nm),
“blue” (470 nm), “true green” (528 nm),
“yellow” (590 nm) and “red” (615 to 625 nm). The LEDs
employ LED chip technologies from Osram, based on either the InGaN (Indium
Gallium Nitrite) material system or InGaAlP (Indium Gallium Aluminum Phosphite)
depending on the wavelength.
The company says that low forward voltages and optimized light extraction
result in high luminous efficacies for all of the new LEDs. The “deep
blue” version, for example, delivers a light output of 140 mW (at 100 mA
and 25 ºC), corresponding to a typical efficiency of 48 percent. Efficiency is
defined as the ratio of the amount of light produced to the amount of power
As members of the mid-power class, the color versions of Duris P 5 are ideal
for linear, area or omnidirectional lighting applications in which the light
has to be distributed as uniformly as possible. Color mixing is also said to be
much easier in applications involving several colors.
“The color Duris P 5 versions will give our customers even greater
freedom in designing luminaires. A good example is the combination of white and
colored mid-power LEDs within a luminaire,” said Martin Wittmann,
Product Manager Marketing SSL at Osram Opto Semiconductors, and added,
“The use of the Duris power class also reduces system costs while at
the same time improving the distribution of light and simplifying thermal
Like the white versions in the P 5 family, the package technology of the
colored Duris versions allow them to withstand extremely harsh conditions and
increasing corrosion resistance compared to conventional mid-power LEDs. The
company says that the small component dimensions of only 2.6 by 2.2 mm also
allow good optical control in connection with secondary optics.
Osram Opto Semiconductors points to architectural and signage applications
as uses for the new LEDs. The company also mentions the possibile use of the
Duris color versions in “remote phosphor” applications in which the
converters needed to generate white light are not attached directly to the chip
but are illuminated by “deep blue” LED from a certain distance,
causing them to luminesce. The company says that this remote phosphor
technology results in uniform distribution of light and high luminous
The color Duris P 5 versions debuted at the Osram booth 1001 at Lightfair

Philips Launches High Power Luxeon Z ES Micro-Mini LED
LIGHTimes News Staff
April 17, 2013...Philips has introduced it newest high-power emitter, the Luxeon Z ES. The
Luxeon Z ES offers extremely high color consistency through a 1-step MacAdam
ellipse in warm white color options. It has a micro-footprint, undomed design
and full spectrum availability. The company says it enables high lumen density
solutions with precise optical control. It is ideal for applications such as
retail, where superior beam angles and high efficacy are crucial. Philips
contends that the illumination-grade emitters help lower costs while offering
best in class white light.
Luxeon Z ES is available with below blackbody binning, which Philips says is
a key feature required for superior color perception in specialty retail and
hospitality applications. The company says it offers 10-15 percent superior
Color over Angle (CoA) compared to standard domed emitters for higher Quality
of Light needs in indoor applications. According to Philips, the superior CoA
makes it ideal for GU10, BR30, and A19 lamps. Philips notes that in directional
light sources such as an MR16 lamp, the undomed design allows better optical
coupling for greater luminance at narrower beam angles and better color
consistency than other LED solutions.
The Luxeon Z and Z ES emitters are offered over a range of CCTs from 2700K
to 6500K with 5-, 3- and a first-ever 1-step MacAdam Ellipse binning option.
They come in a combination of different colors, including white CCTs, lime,
blue, PC amber and red. Philips asserts that in outdoor applications, where
beam angle and high efficacy are key, Luxeon Z ES also shines.
“The Luxeon Z ES is a clear example of our commitment to
innovation with the industry’s first LED platform that combines high
luminance in a 1-step MacAdam Ellipse option that offers optical control in the
smallest available footprint,” said Raj Malhotra, Product Line
Manager of the Luxeon Z family. “The micro-footprint of Luxeon Z ES
means that manufacturers can use optical solutions that are 25% smaller, yet
offer the same light quality that larger, domed solutions can achieve. The
Luxeon Z ES will give lighting designers incredible flexibility, reduce costs
and become the foundation for light sources of the future."
Osram Adds White Multi-Chip Ostar Stage LED to Spotlight Range
LIGHTimes News Staff
April 3, 2013...Osram Opto Semiconductors has added the Osram Ostar Stage LEDs. The LEDs
with a low profile design and a glass cover provide 390 lumens in cold white
(10000K) and 210 lumens in warm white (2700K). The low profile and high
brightness, along with the anti-reflective coating provide the basis for
compact spotlights with an extremely narrow beam.
According to the company, these LED packages with four LED di in each are
ideal for use in moving head spotlights on stage, for booth lighting at trade
fairs, and for architectural lighting. The LED achieves a high color rendering
index of 94 for warm white and 74 for cold white.
The LED measures 5.9 mm x 4.8mm, and thanks to a glass cover the package
measures just 1.23 mm high. Instead of the usual lens, the LEDs have a flat
glass cover with an anti-reflective coating, making them ideal for injecting
the light into lens systems.
The Osram Ostar Stage is based on the Osram Ostar SMT platform and is
therefore suitable for standard solder processes. The company says that the
chips are fabricated with thin-film technology so that almost all the light
produced internally is emitted At a typical value of 1.8 K/W the thermal
resistance is very low. In constant use the LEDs will last for more than 50,000
Osram says that the device’s etendue (the emission angle/area ratio of
the emitting light surface to the projected light surface) in conjunction with
external optics is retained, enabling a very narrow beam of light (+/- 9°) to
be produced. This beam is smaller by factor 2 than for spotlights based on
plastic-encapsulated LEDs. Consequently, the luminance of the spotlight is
greater by factor 2.
The LEDs can be used in spotlights of any size, from small stage spots to
large moving heads. Wolfgang Schnabel, LED Marketing Industrial Applications at
Osram Opto Semiconductors, said, “Three versions of the Osram Ostar
Stage LED are available, the Multi Color (RGBW), the pure white and now the
tunable white. The range of applications is therefore now greater than ever
before. With so many colors and configurations lamp designers have a virtually
unlimited set of options.”
The company will be showcasing the Osram Ostar Stage LED at Prolight + Sound
2013 from April 10 to 13 in Frankfurt.Low-cost LEDs for saving energy and
Cree Introduces XLamp XQ LEDs Delivering Breakthrough Size and Light Distribution
SSLDesign News Staff
March 28, 2013...Cree, Inc. has introduced the XLamp® XQ LEDs, featuring a unique combination
of small size, novel light distribution and high reliability design. These
features enable applications that require broader light distribution such as
omni-directional lamps and fixtures. The XQ LEDs are Cree’s smallest lighting-class LEDs at just 1.6mm x
1.6mm, 57 percent smaller than Cree’s XLamp XB package. The ceramic-based
XQ LEDs leverage Cree’s SC3 Technology™ Platform and are designed
to deliver the long-term calculated lifetimes of Cree’s other high-power
LEDs, such as the XP or XT LEDs.
The LEDs have a novel optic in the shape of an orange cube atop the LEDs.
This cube optic allows some light to both travel through the top of the cube
and light that does not go straight out bounce off the cube’s top. This
directs light to the edges and away from the center. Compared to existing LEDs,
XQ LEDs allow fewer packages to achieve a wide, distributed light pattern that
is ideal for omni-directional lighting.
The company has created two verisions of the XQ LEDs. The XQ-B and the XQ-D.
The XQ-B has a maximum current of 300 mA. The XQ-D has a maximum current of 700
mA. In cool white (5000K), the XQ-B LED delivers up 160 lumens-per-watt at 0.18
W and the XQ-D LED delivers up to 130 lumens-per-watt at 1 W. Both LEDs are
available in 2700K to 6500K color temperatures with minimum 80 CRI option.
According to Cree, the LEDs by themselves can improve the light distribution
of an omni-directional LED lamp. As an example Cree placed the XQ-D LEDs in a
competitor’s omni-directional lamp. Instead of using 27 LEDs to produce
808 lumens, the retrofited omni-directional lamp with inserted Cree LEDs only
needed 16 XQ-D LEDs to produce 819 lumens. The number of watts consumed went
down from the original 10.5 Watts to 9.9 Watts. This translates to a change
from 78 lm/W to 83 lm/W. With the Cree LEDs the viewing angle of the omni
directional lamp improved from 244 degrees to 262 degrees.
Cree also created its own reference design for a 2778K 60-Watt replacement
omni-directional LED lamp that used only 8 XQ-D LEDs to produce 822 lumens with
an 80 CRI and a 69 lm/W efficacy.
“The high reliability of the ceramic based XQ-B LED allows us to
offer a high quality solution that does not compromise on lifetime,”
said Martin Hockemeyer, Vice Chairman of the Board of TELEFUNKEN Licht AG.
“The unique optical advantage of the XQ-B gives us the opportunity to
create the brilliant look that our customers are looking for.”
Paul Thieken, Cree director of marketing, LED components stated,
“Unlike other mid-power packages, the XQ LEDs allow lighting
manufacturers to meet their light distribution requirements using fewer LEDs
without giving up the performance or reliability that they expect from
Cree’s lighting-class LEDs.”
Seoul Semiconductor Targets the LED Outdoor and Streetlight Markets with a New Multi-junction MJT 4040 LED Package
LIGHTimes News Staff
March 22, 2013...>Seoul Semiconductor has announced the new MJT 4040 package which uses the
company’s Multi Junction Technology. The company also announced it
recently won a retrofit project for streetlights using this new product in
China. The multi-junction technology in the MJT 4040 that allows multiple LED
junctions (p-n junctions) to be combined in a single chip. This increases the
operating voltage and concentrates more light output within a given area.
Instead of using the more common 2-3 Volts in an LED, the MJT 4040 operates
at a nominal 64 Volts and 20 mA, because of the multiple p-n junctions. This essentially makes an array of LEDs very close together on the die level as opposed to the package level. The trade-off is that the LEDs that are very close together are hotter.
company says that a (5000K) version of the device can reach output levels of
200 lumens and efficacies as high as 140 lm/watt.
The company notes that streetlights using the MJT 4040 device combined with
the companies Acrich2 technology allows operation on AC current without a
driver, which usually weighs around 2~3kg. Seoul Semiconductors boasts that its
customers can make light-weight LED streetlights. According to the company,
leveraging its Acrich2 technology, streetlights can be designed to use existing
pole infrastructure as well as its functionality (such as existing wiring),
which reduces the retrofitting cost drastically. Seoul Semiconductor says that
reliability is also increased due to reduced component count and the
elimination of electrolytic condensers commonly found in traditional ballasts
Marten Williams, the global marketing VP at Seoul Semiconductor, stated,
“The new MJT 4040 extends the Acrich family of LEDs into higher power
applications and helps our sales team meet the demands of the $1B LED
streetlight market. It is perfect for not only streetlights but parking lot
lights, security lights, low-bays, high-bays and many other outdoor lighting
fixtures. We are currently supplying this product to streetlight manufacturers
in China, South America and other developing countries."
The company is accepting high volume orders of the LED package
