Abstract
    There is still a huge development gap as against the lumen efficiency and world-class(200 lm/W)target for synthesis lighting source GaN LED.Application developments system and material epitaxy,chip fabrication process,device package,latest development of key technology of lighting source GaN LED was also discussed.
