Abstract

LED is used even for traffic light now. But the discernment of the yellow of a signal light and red is difficult for colorblindness. The purpose of this research is to collect the fundamental data for the display of the traffic signal light, which is easy to be recognized also by colorblindness. The results revealed that the optimal brightness of the yellow light from which colorblindness can distinguish the difference between yellow and red, is the area where the yellow is 2.4 times brightness of the red light, considering the effect of energy conservation.
