摘要
A method for enhancing light extraction efficiency of GaN light emitting diodes is disclosed. By cutting off a portion from each end of bottom of a sapphire substrate or forming depressions on the bottom of the substrate and forming a reflector, light beams emitted to side walls of the substrate can be guided to the light emitting diodes.
