At present, the energy consumption of lighting in China accounts for about 15% of the total power generation of society. At present, most buildings control indoor lighting by manual on/off lights. However, it is impossible to optimize and adjust the illumination according to the dynamic change of natural light.
The designer based on the LED intelligent lighting control system, choose to use ZigBee intelligent lamps and Ocean Connect cloud platform mode to build their own intelligent lighting control system. This paper uses ZigBee wireless communication technology to make a set of intelligent lamps, ZigBee is a short distance wireless communication technology, which has the advantages of low power consumption, low cost and low complexity. It is widely used in intelligent lighting system and a trend in the future.
The system uses ZigBee series of single-chip computers as the core and uses BH1750 sensors to measure real-time illumination intensity. In order to realize the unified control of various lamps, it is necessary to make a control protocol and send a control instruction to intelligent lamps. Intelligent lamp control chip adjusts the duty cycle of output current of each constant current driver to control the state of LED lamp.
