通过实验测量额头温度拟合光生物节律因子-额温差曲线,对现有评价光生物效应作用大小的BioEq模型和CLA模型的计算结果进行分析比较.利用不同图片LCD屏幕的光谱计算节律因子, 发现两种模型对于绿色波段的光抑制较强, 而对红色波段的光则与实际不相符.通过对九种不同颜色的LED光源测试额头温度, 比较模型计算结果与实际光生物效应的作用, 发现光生物节律因子与生理体征变化线性递增, 其中对BioEq模型的直线拟合相关度达到0.95.

Two kinds of model, Biological Equivalent model and Circadian Light model which used to evaluate the biological effect of light were discassed and the differences between them were pointed out by fitting curve between the biorhythm factor and human body temperature after several field test. Calculating with the spectrum produced by the LCD screen, it shows that these two models have a stronger restraint of green light band while the red band of light appear not too consistent with the actual results. By tested the forehead temperature under different colors of LED light and fitting with the calculated biorhythm factor, it demonstrates that the forehead temperature increases with the biorhythm factor linearly. And the linear fitting correlation of biological equivalent model is 0.95.
