LEDs for projection applications
26 October 2011
Opto-Electronics
OSRAM Opto Semiconductors has added another LED to its portfolio for projection applications.
The new OSTAR Compact 2x2 is claimed to be the brightest LED of its type on the market, with no less than twice the brightness in all colours and near record-breaking green values. Its performance makes it well suited for high-power projectors for the commercial and domestic sectors.
With just one set of red, converted green and blue OSTAR Compact LEDs, it is possible to achieve a luminous flux of 400 lm from the projector. The new version has been designed specifically for imager diagonals between 10 and 14 mm. If multiple sets of the LEDs are combined for larger imager diagonals, the high projector brightness levels needed for office applications can be achieved.
The LED package has dimensions of 5,8 x 4,6 mm and an output of 85 lm per mm² of footprint. It contains two 2 mm² chips and produces twice the output of the standard Compact LED with one chip.
