摘要

研究了照明光环境对不同年龄人群的光生物效应定量评价方式。从光照转换角度提出了一种考虑不同年龄人眼透射谱、瞳孔直径以及受光面积的节律因子模型，选取3种不同色温（3 000，4 000，6 000 K）的白光LED光源，在同种照度500 lx下实验测试其光谱分布，并对提出的节律因子进行计算，与之前标准中考虑年龄的修正因子方式进行了线性拟合对比分析。结果表明：在相同色温下，随着年龄的增大，节律因子值逐渐减少；而对于相同年龄，随着色温的增大，节律因子是变大的，此种规律与其他研究人员得出的实验结论一致。从线性拟合相关度上来看，三种色温下两种考虑年龄的节律因子的直线相关度分别为0.95808，0.95833，0.95722，具有较高的相关性。较之于标准中的考虑透光谱方式，本文提出了另外一种考虑不同年龄人眼差异的光生物效应评价方式，尝试对人眼模型的透射谱进行绝对而不是相对效应的考虑方式。

Abstract

This paper performed quantitative evaluation of the effects of light illumination environment on photobiological response of different age groups. From the perspective of light conversion

a biological rhythm factor model is proposed considering the ocular transmittances of different ages

pupil diameter and the illuminated area in the retina. Three kinds of white LED light sources (3 000

4 000

6 000 K) with different color temperatures were selected and their spectral distributions were measured at the same illumination 500 lx. Then we calculate the rhythm factors

and make the linear fitting with the evaluation model which use the modified factor proposed in the former standard. The result shows that under the same color temperature

the biological rhythm factor value decreases with increasing age. For the same kind of age

the biological rhythm factor values increases with the increase of the color temperature. These results are consistent with some researcher's conclusion. In addition

according to the result of linear fitting

the linear correlation of two age-related rhythm factors in three different color temperatures were 0.958 08

0.985 833 and 0.957 22

respectively

with a high correlation. Compared with the way in the standard

this article proposed another evaluation model considering difference in human eye age

and attempt to use absolute rather than relative effects of the transmittance.
