Intelligent home LED lighting system based on ZigBee and ARM techniques

The utility model belongs to the technical field of lighting equipment, and relates to an intelligent home LED lighting system based on the combination of ZigBee technique, ARM technique and 8051 technique. The system comprises a wireless gateway, a route, a terminal node, a light control module and an LED lamp. During the work of the lighting system, the wireless gateway is in charge of building and maintaining the network and transmitting the command to the terminal node, the route is in charge of transferring the information between the gateway and the terminal node, the terminal node is in charge of converting the command information into the pulse-length modulation signal, and the light control module is in charge of converting the received pulse-length modulation signal into the current for driving the LED to give out light. Based on the ZigBee technique, the intelligent home LED lighting system has intelligent home lighting function, is convenient to use, and has the characteristics of high reliability, low price and energy-saving effect.
