Research on Energy Saving Control of Lighting Systems in Public Buildings

Most indoor users are unwilling to adjust the lighting equipment and shutters in daily life, resulting in increasing energy consumption of buildings. In this paper, in order to reduce the energy consumption, using fuzzy control to solve this problem. By using fuzzy control, it could control the opening of indoor lamps, and let the shutters could determine the opening degree of the shutters according to the difference between the set illuminance values and the actual illuminance values on the working surface. The results show that the fuzzy control of classroom lighting system can reasonably control the running status of lamps according to the actual situation of the environment and reduce the energy consumption of the lighting system. Compared with the single fuzzy controller, the double fuzzy controller of the shutter can make the difference between the illuminance value of indoor working surface, and the set illuminance value smaller, control the light sources in different areas of the room, and improve the uniformity of natural light in the room. The method proposed in this paper can solve the energy consumption problem.
