OSTAR Projection awarded
OSRAM Opto Semiconductors' highly specialised lightsource is Product of the Year 2007
OSTAR Projection
Readers of the German magazine "Elektronik&Entwicklung" chose the powerful lightsource as winner in the category "optoelectronics & display". A big award for a small light source!
The 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.
The 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.
