摘　　要：根据人眼对不同波长光辐射光生物效应响应度的差异,为提高照明舒适性,以公路隧道常用照明光源高压钠灯和三种不同色温的白光LED分别作为唯一的照明光源,在不同环境亮度条件下,测试了被试者对相同闪烁视标的闪光融合频率值(FFF)。统计结果显示,相同光源对应的闪光融合频率与环境亮度成正比,相同环境亮度条件下高压钠灯对应的闪光融合频率最小,高色温白光LED的闪光融合频率大于低色温白光LED。通过人眼司辰视觉光谱效率函数和光源发射光谱计算得到表征人眼光生物效应影响程度的"司辰亮度",其数值与闪光融合频率试验结果相一致,对人眼光生物效应影响显著的光源对应的闪光融合频率越大,即对疲劳抑制的作用效果越明显。According to the difference of human optical response to different wavelengths of light radiation,in order to increase lighting comfort,light sources commonly used in highway tunnel were tested respectively as the only light source.Samples involved are high pressure sodium lamp（ HPS） and three kinds of white LEDs with different correlated color temperature（ CCT）.At different background brightness conditions,the flicker fusion frequency（ FFF） of subjects were tested and recorded.Statistics showed that the FFF value of the same light is proportional to the background brightness.Under the same background brightness the FFF of HPS is the minimum,and the sample of white LED with higher CCT has higher FFF than white LED with lower CCT.The＂citopic brightness＂was calculated by human citopic vision spectral efficiency function and emission spectra of lamp samples.It can be used to characterize the biological effects of human vision.Citopic brightness values were consistent with the results in FFF test：the lamp sample with significant influence on the biological effects showed higher FFF,meaning on the inhibition effect of fatigue was more obvious.
