To improve the accurate and smart control of the luminance system, a smart luminance control system of LED based on luminance measurement was proposed. The system consists of sensors, LED circuits,a control interface and a logic control device. Through analyzing the lighting structure and requirements of scenarios, the logic control device reads inputs from light sensors, infrared sensors of the human body, control interface and projector signal by its serial I / O, and subsequently adjusts the LED power through pulsewidth modulation signals to achieve the function of this smart system by comprehensive parameter control. The system can be adjusted flexibly according to the specific requirements in different lighting conditions, realizing the accurate control in the multi-areas
