Abstract

This study aims to investigate the effect of light on visual comfort. Experiments had been carried out in a climate chamber. The experiments contained three color temperature levels (3000, 4000 and 5700 K) and three illuminance levels (100, 300 and 500 lx). Sixteen subjects participated in the experiments. Subjects’ visual comfort was evaluated by questionnaires, including brightness, joviality, color authenticity, relaxation, and alertness. Visual evoked potentials were measured to evaluate the transmission of visual nerve pathways. The entropy method was used to determine the weight of the subjective indicators. The results showed that the light environment of 300 lx and 5700 K color temperature is the most comfortable environment. The latency of P100 was minimal when the illuminance was 500 lx under 3000 K, which indicated the nervous system reflects the fastest in this light environment. This study is beneficial to improving indoor environmental workplace satisfaction.
