Light Emitting Diodes (LEDs) play an essential role in lighting and green earth activities because of their high efficiency, longevity and reduction of carbon dioxide emissions in illumination. However, the brightness level of LED light sources must be adjusted appropriately for backlight source or illumination, so Pulse Amplitude Modulation (PWM) is a commonly used method of LED control. This paper experimentally investigated the human visual comfort effect of the light effect obtained using different PWM frequencies on an object in a sensor-based intelligent lighting system. The histograms of the object were created according to the light frequency and the results were discussed.
