Effects of flicker on vision in LED light source dimming control process

With the capability of high precision dimming control accessibility, the white LED is widely used in research of new dimming control method. Research effects on human feeling in dimming control process, especially effects on human vision, is the precondition of the optimal LED dimming control method research. In this paper, an experiment for finding the optimal dimming control method to increase human vision during the LED dimming control process is proposed and experimentally demonstrated. The experiment result shows that people will have the best vision when the LED light source is driving by the double S dimming control method. It is significant meaning of this research in the illumination dimming control field.
