摘要：
Non-image-forming lighting effects reveal the multiple circadian influences of light on human behaviours. A psychophysical experiment was conducted in two sessions (morning and afternoon) for 60 days. The experiment was designed to explore the influence of different circadian lighting by spectral tuning with controlled CCT and illuminance on attention level, brain activity, and sleep quality by measuring PVSAT, EEG, and PSQI, respectively, by 20 participants. The results showed that the white lighting of high circadian stimulus level and high melanopic irradiance significantly enhances the attention level, brain activity, and sleep quality compared to low circadian stimulus level.
