| 摘 要： | 由视觉可靠性的要求,分析了阈对比和背景亮度之间的关系;根据夜间行车时前照灯的实际照明环境,讨论了眩光在人眼视网膜上形成的等效光幕亮度及产生的失能眩光;等效光幕亮度的增加导致对比度下降并使眼睛出现失能;最后给出了当光强增大时由于对比度下降而造成失能眩光出现的实验结果。

| Abstract: | In view of the requirement of sight reliability,the relationship between contrast and the threshold of contrast of light's brightness is analyzed. In terms of the natural illumination environment of headlight in the night,mainly discussed is the disabling glare caused by equivalent brightness which covers the normal brightness of retinas. Increasing of equivalent brightness results in the reduction of contrast of light's brightness, then the eyes will lose their function. The experiment results of disabling glare's generation with the reduction of contrast of light's brightness are presented. |
