Investigation and Experiment of Dynamic Light Disturbance

Abstract

Dynamic obtrusive light is one of latest light pollutions. In the general situation, the human eye can correctly observe and judge the outside things, such as the size, the shape, the color and so on. If the light color is much too complicated, the color area too small or the change of multicolor light too quick, the resolving capacity and the adaptive capacity of the human eye have a decrease. The impression investigation on dynamic lighting and static lighting was performed. The experiment lays emphasis on the influence of dynamic light pollution on visual perception of the general public by measuring subjects' contrast response under different experiment conditions. The influence of background brightness on subjects' disturbance was discussed and the correlation analysis was performed by SPSS. The results indicated that the flickers from some artistic lighting, such as the LED neon light, the stroboscopic light, laser, etc., result in light pollution. The dynamic light pollution can exert influences on the people’s psychology and emotion and even can cause the traffic accident and the visual damage.
