摘要：
In this paper, the phosphor-converted white light LED was studied. Samples under investigation included various types of GaN blue LED chips and phosphor powders with different concentrations. Using an integrating sphere and spectrometer system, the effects of blue LED chips and phosphors on the optical performance of white light LED were analyzed comprehensively. From the experimental study, several conclusions could be drawn. The relationships between the radiant flux of the blue LED chip, the spectrum of the LED and the phosphor, and the optical performance of the resulting white light LED are discussed in detail in this paper.
