为探讨环境照明对安全标志识别过程中视觉疲劳程度的影响，以照度和色温为环境变量，设计了12种混合光照环境，通过眼动追踪技术，测试不同条件下受试者的眼动数据并进行双因素方差分析，结合反应速度和舒适度的测试结果，分析在不同光照条件下的视觉疲劳变化。实验结果表明：照度的变化对视觉疲劳有显著影响，在低照度环境中受试者更易出现视觉疲劳；色温的变化对视觉疲劳的影响相对较小，但在不同混合光照环境下，色温的变化会影响受试者的视觉舒适度，疲劳状态随之发生改变。作业环境照明条件中较为适宜的色温范围为2 100 ~ 3 500 K，照度范围为550 ~ 900 lx。可见企业要重视生产过程中照明条件的改善，避免因视觉疲劳而降低作业人员对安全标志的识别效率，确保劳动者的安全与健康。

In order to explore the influence of environmental lighting on visual fatigue during safety sign identification, 12 mixed lighting environments were designed with illuminance and color temperature as environmental variables. Eye movement data were tested under different conditions by eye-tracking technology and a two-factor ANOVA was conducted. Combined with the test results of reaction speed and comfort, the changes of visual fatigue under different lighting conditions were analyzed. The experimental results show that the change of illumination has a significant effect on visual fatigue, subjects are more prone to visual fatigue in low illumination environment; The change of color temperature has little effect on visual fatigue, but in different mixed lighting environments, the change of color temperature will affect the visual comfort of the subjects, and the fatigue state will change accordingly. The suitable color temperature range for the lighting conditions in the working environment is 2 100 ~ 3 500 K, and the illuminance range is 550 ~900 lx. It is concluded that companies should pay attention to improving the lighting conditions during production, avoid reducing the recognition efficiency of safety signs by workers due to visual fatigue, and ensure the safety and health of workers.
