最近的一项研究探讨了亮度和光谱功率分布如何影响面部表情的识别，这是行人对其他人明显意图的判断的代理。本文描述了一项重复研究，其中包括更多的测试亮度，第三种类型的灯，和一个额外的，更短的观察时间（500毫秒）。亮度和距离对表情识别有显著影响;灯的影响不显著，持续时间的影响仅在性能与亮度关系的悬崖区域内显着。结果被用来估计户外照明的适当光照水平。1.0 cd/m2的亮度允许在15 m的距离处以50%的正确识别概率识别面部表情。
A recent study examined how luminance and spectral power distribution affect recognition of facial expression, a proxy for pedestrians' judgements concerning the apparent intent of other people. This paper describes a repeat study which included a greater number of test luminances, a third type of lamp, and an additional, shorter duration of observation (500 ms). Luminance and distance had significant effects on expression recognition; the effect of lamp was not significant and the effect of duration was suggested to be significant only within the escarpment region of the performance versus luminance relationship. The results were used to estimate appropriate light levels for outdoor lighting. A luminance of 1.0 cd/m2 permits facial expressions to be identified with a 50% probability of correct identification at a distance of 15 m.
