摘要:In order to research the dynamic visual performance of LED in mesopic vision conditions, based on the visual performance method, the software systems were developed to set different test parameters. And the hardware systems were used to collect the reaction time of testers. Color temperature of LED, ambient luminance, luminance contrast and target speed were selected as the experimental variables, and each variable had three variances. 60 sets of experiments were carried out by 20 testers. The experiment results show that reaction time of high color temperature LED is shorter than the other two. And reaction time decreases with the increasing of the ambient luminance and luminance contrast. And target speed has significant influence on visual performance in the speed range of 60km/h to 80km/h.
