Philips Lumileds shatters performance records
Philips Lumileds, the pioneer and the leader in high-power LED technology, announce new performance records for high-power white LEDs.
* For white devices, luminance of 38 meganits (Mcd/m2), approximately 50% more luminance than that of an automotive headlamp halogen bulb (~25 meganits) was achieved.
* For InGaN blue devices, a radiance of 200 mW/mm2sr was realised.
* For InGaN green devices, luminance of 37 meganits (Mcd/m2) was achieved.

Philips Lumileds has fundamentally solved problem of 'droop', a phenomenon common to white power LEDs in which efficacy (lumens per watt) decreases as current increases.

New lighting possibilities with Luxeon K2 LEDs
Philips Lumileds announce availability of warm-white and neutral-white Luxeon K2 emitters as well as a Luxeon K2 Star part that can be specified with any standard white emitter.
These solid-state light sources-that fit on the head of a matchstick-demonstrate light output performance levels well beyond what is possible from today's state-of-the-art LEDs and are indicative of the evolutionary research and development work being done at Philips Lumileds.
These achievements will significantly affect the performance and design of light intensive applications such as automotive headlamps, rear-projection televisions (RPTV), and commercial lighting.
In the automotive headlamp arena, new white LED products based on these advances will generate light density exceeding that of the halogen bulb commonly used in automotive headlamps and require a fraction of the physical space.
High precision mounting and alignment of the new products in development will yield better light control, resulting in significantly smaller and more efficient headlamps than those built with conventional technologies.
Combined with higher visibility white performance, LEDs will change the shape of automotive forward lighting.
LED RPTVs, one of the most talked-about consumer technologies at this year's CES in Las Vegas, are limited in brightness by the light output of current LEDs.
Philips Lumileds anticipates that the luminance demonstrated with its new technologies will enable front-of-screen performance brighter than any LED-based RPTV that has been publicly demonstrated.
The new solid-state devices would also remove barriers to increased display size, and superior contrast and colour uniformity.
The entire system is improved and the viewers' experience enhanced with improved color gamut, lower profile systems, longer lifetime and reduced ownership costs.
In the lighting category, applications such as aircraft, roadway and general lighting will benefit from the greatly improved light output performance and the innate ability of solid-state lighting to operate in very cold environments, withstand significant shock and vibration, and be controlled digitally.
Worldwide, Philips Lumileds expects that its advances in solid-state lighting will ultimately save billions in energy costs and have a significant positive effect on the environment.
These advances mark the latest chapter in Philips Lumileds' pioneering research and development for solid-state lighting technologies, enabling never-before-possible commercial applications that disrupt conventional lighting assumptions.
The company's LUXEON power LEDs, including LUXEON Flash and the recently released LUXEON K2, continue to transform lighting solutions around the world with their industry-leading brightness, lumen maintenance, conformal coating process for creating a uniform white beam, and other advanced features and capabilities.
