Abstract：According to analysis of the working principle of the traditional LED shadowless system and the current development trend of intelligent lighting, this article will propose a shadowless LED intelligent Constant light system implementation scheme. The system uses multiple ultrasonic sensors fuzzy logic data fusion algorithm to to determine the location of the obstruction which caused the shadow during a surgery, then automatically produce LED lighting-source group driving scheme based on the judgment result, and eliminate shadows in a real-time method. The shadowless LED intelligent constant light system constructs a PID closed-loop feedback regulation by utilizing the TSL2561T, a digital photoelectric sensor, to get the real-time feedback data of lighting, and bases on indirect measurement to measure the lighting conditions of the operating table surface, then the system carries out an intelligent adjustment to fit the LED brightness to meet the surgery needs on the operating table. After several experiment and observations, the system under different lighting conditions maintains a constant brightness within the range of light and it can accurately determine the location of the obstruction which in the light range and utilize the stepless adjustment to erase the shadow of it efficiently.
