Osram develops blue thin-film InGaN LEDs

"SAN JOSE, Calif. -- Osram Opto Semiconductors GmbH said on Wednesday (September 3, 2003) that it has introduced to the market blue 'thin-film' light emitting diodes (LEDs) that would enable the use of LEDs in vehicle headlights, amongst other applications.

Developed using InGaN technology the LEDs make it possible to extract up to 75 percent of the internally generated light from the chip, the company said...."

16mW isn't a whole lot for vehicle headlamps. Wonder how they're going to scale that up since the whole thrust of high power LED's is thermal management and they don't mention that critical portion of the design. Also wonder what Lumiled's efficiency is compared to Osram's 75% light extraction. Interesting info, by the way, thanks for sharing with us.
