Abstract: White LEDs have many advantages, including high luminous efficiency, low power consumption, long lifetime and pro-environment, which other traditional lighting sources can pared. therefore, White LEDs are regarded as the most potential lighting source in replacing the currently used incandescent and fluorescent lamp. According to the latest research progress of semiconductor illumination, the tendency that indoor lighting used GaN-based White LEDs is introduced in this paper .The main problems in widespread use of White LEDs in general lighting are detailed discussed and analysed in terms of its visual Indexes ,packaging technology,cost and so on. finally, the development prospect of White LEDs is analysed based on existing methods.
