OSRAM Opto Semiconductors GmbHRequest Info
 
For the consumer electronics market, Osram Opto Semiconductors GmbH has launched Ostar Projection, a module consisting of six LED chips. The 1-mm2 chips use thin films to deliver surface emissions in red (617 nm), green (517 nm) and blue (655 nm). A pocket projector equipped with these three light sources can produce 120 lm without optimization or up to 140 lm with thermal, optical or electrical optimization. The chips have a thermal resistance of 2 K/W for effective heat dissipation, they last up to 50,000 h, and the color gamut can exceed the NTSC standard.
