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.

Vision X Lighting recently launched its first product using a single Luminus LED called Light Cannon. Light Cannon can produce a usable beam of light at a distance of more than 1,000 feet.

"We couldn't be happier to announce our partnership with Vision X Lighting, a world-class company at the forefront of innovation," said Jim Hunter, VP & general manager of global commercial markets at Luminus. "At Luminus, we excel at providing our customers with high brightness LEDs that produce thousands of lumens. As demonstrated through our partnership with Vision X Lighting, we enable our customers to create exciting lighting products capable of delivering high brightness light at great distances with unprecedented center beam candle power."

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 consumed.

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 management.”

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 efficacy.

The color Duris P 5 versions debuted at the Osram booth 1001 at Lightfair 2013

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."

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 hours.

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 improving health.

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.”

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
