OSRAM Opto Semiconductors Announces Ostar Projection

San Jose, CA - OSRAM Opto Semiconductors, a light-emitting diode (LED) technology,recently announced its innovation, OSTAR Projection, designed for products in the consumer electronics market. The OSTAR Projection module consists of six LED chips, which generate exceptional brilliance and vibrant colors for computer games, videos and presentations.

"We're very excited to bring the revolutionary OSTAR Projection technology to the consumer electronics market," Ellen Sizemore, director, LED/IR marketing, OSRAM Opto Semiconductors Inc., said. "OSTAR Projection offers powerful monochromatic LED light sources for use in small portable projection displays with sufficient brightness in average room lighting."

The six one mm^² chips use proven thin-film technology and deliver highly efficient surface emissions in red (617 nm), green (517 nm) and blue (655 nm). A pocket projector equipped with these three light sources provides a system brightness of 120 lumens, and a possible 140 lumen value with thermal, optical or electrical

optimization. The new material base for the metal core board offers a thermal resistance of 2K/W so the heat generated can be efficiently dissipated.

Equally important, the color gamut possible with the use of the OSTAR Projection LEDs can exceed that specified by the National Television Systems Committee (NTSC) standard.

OSTAR Projection is offered in two package versions, each with different chip orientations, which provide flexibility in mechanical layout to make smaller projectors.

With a lifespan of up to 50,000 hours, the new OSTAR Projection far exceeds the lifespan of conventional projection lighting systems.
