摘　　要：本文从明视觉、暗视觉及非视觉的三条光谱灵敏曲线出发,讨论不同视觉状态下,光源光谱对人体的作用。通过测量各种常见光源的光谱,计算暗明比s/p值和生物节律影响因子acv值,对光环境进行评价。另外,选取一天中自然光在各整点时刻的分布状态,计算acv值,比较人工光源和自然光源的差异,从而得到色温对s/p值和acv值的影响,为高效、健康的光源选择提供依据。Disscusion on the effects of spectra on human body is conducted in this paper on the basic of three different spectral sensitivity curves： photopic vision, mesopic vision and non-visual biological effect. Lighting conditions are evaluated through the measurements of spectra of light sources in common use and the calculation of both s/p and circadian impact factor acv . In addition, the distributions of natural light are recorded every one hour for the calculation of acv, then the comparation between artificial light and natural one is conducted and the effects of color temperature on s/p and acv are concluded, which can be refered to for the selection of efficient and healthy light sources.
