Osram Opto Semiconductors announced OSTAR Projection, designed for products in the CE market.

The six 1mm² chips use thin-film technology and deliver efficient surface emissions in red (617nm), green (517nm) and blue (655nm) wavelengths. 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 optimisation.

The material base for the metal-core board offers a thermal resistance of 2K/W so the heat generated can be efficiently dissipated. OSTAR Projection is offered in two package versions, each with different chip orientations, and has a lifespan of 50,000hrs.

OSTAR Projection is suitable for computer games, videos and presentations. Samples of the product are available.
