Luminous Efficacy

Luminous Efficacy Tables

发光效率表

The light sensitivity of the normal human eye has been studied extensively. The response of the eye as a function of frequency is called the luminous efficacy of the eye. It has been tabulated for both the light-adapted (photopic) case and the dark-adapted (scotopic) case.

人类正常眼睛的光灵敏度已被广泛研究。眼睛对频率的响应称为眼睛的光效。它已分别列出在光适应（视光适应）和暗适应（视暗适应）两种情况下。

来源：Table 6-1 of Williamson & Cummins，《自然与艺术中的光与色》，Wiley，1983年。光觉转换（lm/W）是将V λ乘以683得到的，而视觉转换则是将V' λ乘以1700，如该作者所建议的。
