Philips Lumileds sets LED luminance records
- Details
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 200mW/mm2sr was realised.
For InGaN green devices, luminance of 37 meganits (Mcd/m2) was achieved.
"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 d
