Low-light environment affects human physiology, psychology, and behavior. It causes errors in work and increases accidents. In this study, we built a coal mine lighting simulation experiment system. The system not only includes an experimental environment simulation system and a physiological indicator test system, but also adds a miners’ working simulation system. We aim to study the effect of different illumination levels (0lx, 10lx, 50lx, 100lx, and 200lx) on three indicators: heart rate, electrodermal activity, and respiration. The results show illuminance has a significant negative correlation with all the above three indicators. Heart rate seems to be most significantly affected by illuminance, and it changes significantly from the normal level (200lx) at 50lx. By contrast, the respiratory rate and electrodermal activity change significantly at 10lx. When the illuminance is 50~100lx, all the three indicators return to the normal level. The results suggest that coal mine illumination should be around 50~100lx. When the minimum illumination is less than 10lx, accidents tend to increase.

弱光环境影响人的生理、心理和行为。它会导致工作错误并增加事故。在本研究中，我们构建了一个煤矿照明模拟实验系统。该系统不仅包括实验环境模拟系统和生理指标测试系统，还增加了矿工工作模拟系统。我们旨在研究不同光照水平（0lx、10lx、50lx、100lx 和 200lx）对三个​​指标的影响：心率、皮肤电活动和呼吸。结果表明，照度与上述三个指标均呈显着负相关。心率似乎受照度影响最为显着，在 50lx 时与正常水平 (200lx) 发生显着变化。相比之下，呼吸频率和皮肤电活动在 10lx 时发生显着变化。照度50~100lx时，三项指标全部恢复正常。结果表明，煤矿照度应在50~100lx左右。当最低照度小于10lx时，事故往往会增加。
