The realization of the use of phosphor white high power led are mainly three methods, but they did not fully mature, thus seriously affecting the area of white LED lighting applications. Specifically, the first method is the blue Super Bright LED chip can be coated with yellow phosphor-ray excitation, the blue-chip issue and issued a yellow phosphor to form white light complement each other. The technology monopoly by the Japanese company Nichia, and this program is the principle of the shortcomings of the phosphor of Ce3 + ion emission spectra of the spectral properties of non-continuous, less color, it is difficult to meet the requirements of low color temperature superflux LED, at the same time Luminous efficiency is not high enough, need to develop new phosphors to improve the efficiency. The second method is the blue bi color led chip coated with green and red phosphors, issued through the chip and the phosphor blue and red light green tri color led given compound to be white, of good color.However, this approach effectively used phosphor conversion efficiency lower, in particular the efficiency of red phosphors need to improve greatly.
