Osram Opto Semiconductors has developed the next generation of its bright Ostar Headlamp LED. This LED is more than twice as bright as its predecessor, which at 250 lumens was already one of the top performers in its class. At an operating current of 700 mA this high-power light source now achieves peak values of up to 620 lumens, yet consumes only 12 W. The high-power LED has no lens and its five chips are connected in series, producing light with a color temperature of 6000 degrees K. In the future, three or four these LEDs will be enough to produce the 1000 lumen required for headlights.

The package has been designed to minimize reflections. Osram's thin-film chip technology, in combination with an improved phosphor converter, accounts for this LED's high luminance and improved efficacy with minimum space requirements.

Operating without a lens, the high brightness of the new Ostar headlamp LED has been achieved through a combination of measures. Samples of the new Ostar Headlamp LED are available, with volume production to begin in the third quarter of 2008.

Osram Opto Semiconductors GmbH of Regensburg is a wholly-owned subsidiary of Osram. It offers its customers solutions based on semiconductor technology for lighting, sensor and visualization applications. The company operates sites in Regensburg, Germany, San Jose, Calif. and Penang, Malaysia.
