Abstract: lighting electricity is a basic power demand of the school. The school has many characteristics, such as large area, large number of rooms, large number of lamps and basic fixed rest time. If the traditional lighting control is adopted, the power waste is often caused by many wiring, unable to make full use of natural light, and the control trouble is inevitable because of forgetting to turn off the lights. In order to achieve the control effect of energy saving optimization, schools can use Smart lighting control system to manage school lighting. Compared with the traditional lighting control mode, the Smart lighting control system has simple wiring, flexible and convenient control, and can save electric energy.
