LED Technology Is Still Young

Thanks to the new high-brightness green LEDs, the LED projectors of the future will be able to produce images with diagonals of several meters. The projected images themselves will appear brighter than those produced by conventional light sources with similar lumen rating thanks to the saturated colors of the LEDs used.

OSRAM Opto Semiconductors has developed a pre-production green LED based on the OSTAR platform that is twice as bright as its predecessors and has a luminous surface that is perfectly uniform. This single-chip LED benefits from the latest chip technology and a green phosphor converter. Initial samples are already available, and OSRAM is currently working with partners to develop appropriate LED data projectors such as those used in the office and education markets. OSRAM Opto Semiconductors expects the LED to be widely available to projector manufacturers in the summer of 2011.

OSRAM will be showcasing these high-powered green LEDs to invited customers at the 2011 International CES (Consumer Electronics Show), Las Vegas, NV, January 6-9, 2011.
