Bridgelux has made a breakthrough on the 135 Lumens per Watt GaN-on-Silicon based LED Technology, which marks the industry's first commercial grade performance for a Silicon-based LED.
The 135 Lumen per Watt performance was achieved at a CCT of 4730K using a single 1.5mm power LED operated at 350mA. These LEDs operate just 2.90V at 350mA and < 3.25V at 1 Amp. Optimization of the epitaxy process on 8-inch Si wafers will make LED manufacturing compatible with existing automated semiconductor lines.
It’s said that the company will leverage its strong R&D and Intellectual Property position in LED epitaxy to jointly manufacture silicon based LEDs.
Currently, it is in discussions with a number of established semiconductor companies regarding the utilization of the many fully depreciated 8-inch semiconductor fabrication operations available all over the world.
