本论文反映了一项正在进行的工作，对昼夜节律光的定义，一个应该被告知的深思熟虑的，百年的演变，我们目前的光作为刺激人类视觉系统的定义。这项正在进行的工作是基于光学辐射和它对夜间褪黑激素抑制的影响之间的函数关系，在很大程度上是因为基本数据可在文献中。这里讨论的是视觉系统和昼夜节律系统对光辐射的反应之间的根本差异。简要回顾光度学，色度学和亮度感知的基础上提出的昼夜光的讨论。最后，昼夜光（CLA）和昼夜刺激（CS）的计算程序的基础上公布的数学模型的人体昼夜光转换的例子。
The present paper reflects a work in progress toward a definition of circadian light, one that should be informed by the thoughtful, century-old evolution of our present definition of light as a stimulus for the human visual system. This work in progress is based upon the functional relationship between optical radiation and its effects on nocturnal melatonin suppression, in large part because the basic data are available in the literature. Discussed here are the fundamental differences between responses by the visual and circadian systems to optical radiation. Brief reviews of photometry, colorimetry, and brightness perception are presented as a foundation for the discussion of circadian light. Finally, circadian light (CLA) and circadian stimulus (CS) calculation procedures based on a published mathematical model of human circadian phototransduction are presented with an example.
