Abstract：Luminous efficacy of radiation ( LER) is a vital property of a spectrum , and directly determines the theoretical luminous efficacy of white LEDs .This paper proposes an approach to calculate the spectral power distribution of white LEDs at a certain CCT in CIE colorimetric system , and discusses the trend of LER changing with target CCTs and parameters of primary spectral models .It provides a way to the spectrum optimization of high-efficiency LEDs.
