A street lighting system is an indispensable part of an urban infrastructure, and as a part of municipal public facilities, it is closely related to people's daily life. In this paper, the development of a street lighting system technology is described, with the shortages of the current technology pointed out. A method of the ZigBee based wireless sensor network in LED street lighting system is presented, and an LED street lamp energy-saving control system is discussed. In the end, according to the above mentioned, the architecture of a ZigBee based Wireless Sensor Network is designed and discussed in detail.
