EXPERIMENTAL RESEARCH OF DYNAMIC LIGHTING SCHEMES ON IMPROVING THE NEGATIVE EMOTION OF LOW VISION PATIENTS

By changing the brightness of functional lighting and the colour of ambient lighting, the facial expressions of patients with low vision were monitored and the changes of their negative emotions were analysed.In the day ward of the eye hospital, 16 patients were randomly selected as subjects and divided into 4 groups on average.One group was the reference group with only functional lighting, and the other three were the intervention group with additional coloured ambient light.The results showed that the gender difference was not significant, the negative emotions in the reference group were significantly higher than those in the experimental group, and the improvement effect of the emotional lights in the p urple, orange and blue groups was significant, among which the orange group had the best effect, while the blue group and the purple group had better effect, but the difference was not significant.
