Visual Perception of LED Flickering Controlled in a Colored Environment

Abstract

Flickering is a phenomenon associated to light sources. This flicker is at 100 Hz in Europe and although at this frequency, people don ʼ t perceive it consciously, there could be some health impact. We examined the limits of visual perception so that we can determine whether flickering can be used to our benefit. The parameters of frequency and duty cycle were explored as well as the impact of the background color on the perception.
