Developers at OSRAM Opto Semiconductors have succeeded in increasing the efficiency of red thinfilm LEDs by 30% - a new record. The latest generation of thinfilm chips benefit from an optimized chip platform which has potential for further improvements. This boost in efficiency is opening up new LED applications in general illumination, in projection and in the industrial sector.
The record efficiency for an LED of 119 lm/W at an operating current of 350 mA (136 lm/W at 70mA) has been achieved by the latest generation of a red 1 mm² thinfilm chip (InGaAlP).
