Abstract：This paper researched an LED intelligent dimming system based on multi-sensor fusion technology . This system firstly calculated the weighted average value of measurements of multiple photosensitive sensors , then compared it with the setting value , so that the PWM control signal could be adjusted to implement intelligent LED light dimming .Meanwhile , infrared sensor was applied to detect whether there are people in the current environment or not , in order to control the LED lamps shutting off or turning on automatically .This system could mainly be applied in the place where there are lots of lamps and longtime lighting is needed such as classrooms and offices .Secondary energy saving of LED lamps was implemented in this system .
