Abstract: The traditional production method of white light LED is adding YAG phospher on blue light chips which causes two-wavelength white light that is only suitable for indication usage. Moreover, the difficulty in controlling adequate amount of phosphor powder leads to inaccurate color of light. Another production method for three wavelength white light by UV ehip arousing R.G.B.-mixed phosphor powder is degenerated in its life and quality due to lack of high-efficiency UV LED chips and UV-typed encapsulating resin. The production method of white light LED of the present invention consists of packaging substrate, purple light LED chip and R.G.B.-mixed phosphor powder. With purple light produced by purple light LED chips to arouse phosphor powder on the surface, the three-wavelength (tri-color) white light formed by R.G.B. lights takes shape. The present invention is the best choice in producing high brightness and three-wavelength (tri-color) white light LED.
