Abstract
The performance of InGaN/YAG white LEDs for lighting applications is reviewed. Advanced small-chip-technology has achieved high-luminous efficacy white LED of almost 200lm/W by improving internal efficiency, extraction efficiency and electrical resistance. In addition, high-luminous flux device of 10,000lm by flip-chip array has been also developed by large-chip-technology.
