Six chips make the new OSTAR Projection from OSRAM Opto Semiconductors exceptionally bright.
In mini projectors they help create vibrant colors for computer games. With a system brightness of 120 lumen, games and other screen content can be projected onto walls in large format.
Serious computer users and gamers will be amazed. The six-chip version of OSTAR Projection offers strong monochromatic LED light sources that make pocket projectors brighter, more vibrantly colorful and more flexible. Games and other screen content no longer have to be viewed only on a small display. Instead they can be enjoyed in large format and in brilliant colors when projected onto a wall. There is no longer any need to huddle over a small screen.
OSTAR Projection is available in Red (617 nm), Green (517 nm) and Blue (464 nm). This means that more colors and color tones in the color triangle can be displayed than prescribed by the NTSC standard (National Television Systems Committee). The six chips, each 1 mm² in size, are fabricated using tried and tested thin-film technology. They are highly efficient at providing the generated light at the surface of the chip. A pocket projector equipped with these three light sources provides a system brightness of 120 lm. By optimizing the system it is possible to bring this value up to 140 lumen. The new material base for the metal core board offers a thermal resistance of 2K/W so the heat generated can be efficiently dissipated. Two package versions with different alignments of the chip surface offer potential customers enormous flexibility in the mechanical design of the lighting system.
The new OSTAR Projection has a lifespan of up to 50,000 hours.
This corresponds to 5.7 years of continuous operation and therefore far exceeds the lifespan of conventional projection lighting systems.

No more huddling over a small screen
OSTAR Projection has an impressive output and a lifespan of 50,000 hours. Customers who do not mind reducing this lifespan can operate the LED light source with a higher current and achieve even greater brightness.
