OSTAR Headlamp LED achieves 620 lumen

The new OSRAM OSTAR Headlamp LED is now more than twice as bright as its predecessor, which at 250 lm was already one of the top performers in its class. The high-power LED does not have a lens. Its five chips are connected in series and produce light with a color temperature of 6000 K. Like all LEDs with thin-film chips, the OSTAR Headlamp offers a high luminance which is further enhanced by the closely packed chips. It can be combined with small optics, takes up very little space and offers designers maximum freedom. At an operating current of 700 mA this high-power light source now achieves peak values of up to 620 lm and consumes 12 W.

In future, three or four OSTARs will be enough to produce the 1000 lumen required for headlights. Initial samples are already available. Volume production will start at the end of 2008.
