Wafer-level light emitting diode (WL-LED): An innovative approach for cost-effective very high power lighting

A very high power wafer level light emitting diode (WL-LED) has been successfully fabricated on 2 inches InGaN/GaN epi-wafer based on high voltage design. The maximum light output power (LOP) was measured to be 157W with an external quantum efficiency (EQE) of 24%.
