A The Study of White LEDs with Red/Green Phosphors and Optical Simulation of LEDs with Patterned Sapphire Substrate
碩士 === 崑山科技大學 === 電子工程研究所 === 96 === Luminous efficiency of LED（Light-emitting diode）must be improved for general illumination. Two well-known methods to increase luminous efficiency are chip mission-side roughness and substrate surface etching. The patterned sapphire substrate, which is etched regu...
