中文摘要	we packaged a series of high power white leds by covering the blue led chips with yellow phosphor, red phosphor and the two phosphors mixed by appropriate mass ratio, respectively, and discussed the excitation and emission spectrum of yellow phosphor and red phosphor and the characteristics of the leds. we found that the luminous efficacy of the white leds covered with the two phosphors mixed by appropriate mass ratio was lower than that of the white leds covered with yellow phosphor, but the color rendering index was improved observably
