The development of LED street lamp control system based on ZigBee network is presented in this paper. Using AVR microcontroller as the core processing chip, the lamp node de-tects the external signal by photoelectric sensor, controls LED lamp lighting in a different way according to the environment light, traffic conditions and timing;using the MBI1802 drive chip constantly drives LED lamp, power regulations are in the range of 20%~100%, adjustment error is less than 2%, constant current deviation is less than 1.7%; communication between nodes and center is realized with ZigBee wireless network, to carry messages of remote control and alarm signal. The results indicate that the system is intelligent, long-distance and energy conservation.
