摘　　要：光视效能的高低直接影响到光源的光效,两基色白光LED存在无数个同色异谱色,它们的光视效能值不同。通过计算确定了可合成白光的两基色的选取范围,确定了得到高光视效能的白光LED的两基色的选取范围。The luminous efficacy of radiation is an important factor influencing to the luminous efficiency of lighting. White LEDs with two primary colours have uncountable metamerism with different luminous efficacy of radiation. The synthetic range of the white LEDs with two primary colours in chromaticity coordinate is determined by colour matching calculation, and the selective range of two primary colours is determined to obtain high luminous efficacy of radiation for white LEDs.
