Abstract
Museum exhibition halls are one of the most visually demanding buildings. However, unique lighting methods, luminance contrast, display cabinet reflections lead to complex spatial luminance distribution and intense glare, thus seriously affecting the visual effect. Modeling accurate glare calculations is an effective way to reduce the risk of visual discomfort. In this study, we obtain the real glare perception in the lighting scenes of museum exhibition halls through small-sample evaluation experiments, and then propose an improved model on the basis of testing the accuracy rate of UGR to be 41.67%, which contains key parameters characterizing the effects caused by multiple glares. Then we optimized the coefficients and power indices according to the real glare perception, and verified that the accuracy rate of glare calculation in museum exhibition halls was improved by 36.46% compared with that of UGR, and gave the glare rating corresponding to the calculated value of the model.
