Effects of color temperature and lighting mode on visual and psychological perception of pedestrians in subway station

Abstract

This paper mainly discusses the influence of artificial lighting environment in a subway stations on pedestrians' visual and psychological perception, which is explained from two potential influencing factors - the relevant color temperature of light source and lighting mode. On this basis, nine lighting environments are subjectively and carefully analyzed by a questionnaire survey. The evaluation results show that the higher the subway ride frequency, the higher the subjective evaluation score; The change of lighting environment also has a significant impact on people perception. In the high color temperature environment, the lighting mode will not affect people perception of warmth. It is worth noting that the ceiling lighting score of the middle color temperature is the highest, which is the most suitable environmental mode designed in the subway station, and the middle color temperature is also the most relaxed color temperature level among the three color temperatures. The basic lighting with warm color temperature is not suitable for application in subway stations. By combining the relevant control technology, we have obtained a relatively suitable lighting scheme for subway stations.
