July 4, 2006 -- Philips Lumileds Lighting Co has established what it claims are new luminance performance records for solid-state lighting technology at 1A.
These solid-state light sources are said to demonstrate light output performance levels well beyond what is possible from today's LEDs and are indicative of the research and development work being done at the company.
These achievements will 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 smaller and more efficient headlamps. Combined with higher visibility white performance, LEDs will change the shape of automotive forward lighting.
LED RPTVs are limited in brightness by the light output of current LEDs. The company 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 also remove barriers to increased display size, and superior contrast and color uniformity. The entire system is improved and the viewers' experience enhanced with improved color gamut, lower profile systems, and longer lifetime.
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.
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 brightness, lumen maintenance, conformal coating process for creating a uniform white beam, and other advanced features and capabilities.
Among the new benchmarks:
-- For white devices, luminance of 38Mcd/m(squared), approximately 50% more luminance than that of an automotive headlamp halogen bulb (approximately 25 meganits) was achieved.
-- For InGaN blue devices, a radiance of 200mW/mm(squared)sr was realized.
-- For InGaN green devices, luminance of 37Mcd/m(squared) was achieved.
