Osram launches brighter, six-chip OSTAR projection light source

Osram Opto Semiconductors of Regensburg, Germany has launched a version of its OSTAR Projection LED light source that incorporates six 1mm2 chips, offering stronger monochromatic light with a system brightness of 120 lumens in pocket projectors (and up to 140 lumen by optimizing the system).

Such mini-projectors can therefore be made brighter, more colorful and more flexible, says the firm. Screen content such as computer games no longer has to be viewed only on a small display but can be projected onto walls in large format.

OSTAR Projection is available in red (617nm), green (517nm) and blue (655nm), so more colors and color tones in the color triangle can be displayed than prescribed by the National Television Systems Committee (NTSC) standard. Two package versions with different alignments of the chip surface offer flexibility in the mechanical design of the lighting system.

The new OSTAR Projection source has a lifespan of up to 50,000 hours, corresponding to 5.7 years of continuous operation (far exceeding the lifespan of conventional projection lighting systems, the firm claims). Alternatively, the source can operate with higher current and greater brightness but with reduced lifespan, says Osram.
