Osram Opto Semiconductors has developed an extremely bright, green light-emitting diode (LED) that makes LED projectors in office environments possible. Projectors in conference rooms have to be very bright for viewers to easily see the large images even in daylight. So far, LED light sources have therefore been used primarily in pocket projectors, cell phones, or home cinema systems. The new diode, which is based on the Ostar product platform, shines twice as brightly as before and its luminous area is very uniform. Beginning in mid-2011 it will be used to open up the office projector market. The first components are now being delivered to customers.
