CIE眩光指数（CGI）的应用研究

不舒适眩光是室内照明质量评价的重要指标，国际上有多种对不舒适眩光评价 的方法，其中ＣＩＥ推荐的眩光指数（ＣＧＩ）公式是目前较好的数学表达方法，但 ＣＩＥ推荐的数学模型仅针对灯具的光轴与铅垂电一致（垂直旋转角为零）的情况， 本文进一步提出了在灯具垂直偏转角不为零时的数学模型，并介绍了作者编制的计 算机软件，这对类似体育馆等有较高垂直照度要求场所的眩光评价，具有较大的实 用价值。

The Application of CIE Glare Index

Discomfort glare is an important criterion for the evaluation of interior Lignting. There are several methods for discomfort glare evaluating in the world.The CIE Glare Index(CGI)Formular which is recommended by CIE,is the easy to computerized one between them, But the CIE recommended mat- hematical model is only applied to the luminaires whose optical axis is coincised with the plumo-line(the angle of verical rotation is equal to zero). This paper revised the mathmatical model and can be applied to the lumin- airea whose vertical rotation angle is not zero.And the authors have developet a computer programme for the CGl System. This programme is very useful for the glare evaluation of the interiors with high vertical illumihance such as gymnasium or indoor football field
