Abstract： Aiming at the defects of the current traditional lighting system about manual operation， complex wiring and so on which can′t meet the requirements of the environmental sampling， linear dimming, the design of lighting control system of LED based on ZigBee wireless sensor network technology was presented CC2530 chip was chosen and Mesh topology structure of ZigBee2007/PRO wireless sensor network was used by the system to acquire realtime environment parameters in lighting scene， such as illumination， moving target， temperature， LED state and so on With the change of environmental parameters and the preset lighting mode, the system can automatically make quick response and realize PWM linear nonpolar dimming The LED lighting control system was realtimely monitored and centralizedly managed by the PC host computer based on the VB60 platform to overcome the defects of traditional lighting inefficient management and staff wastage The results indicate that the system achieves the design goal of the realtime acquisition of environment parameters by sensor nodes， precise control by  ZigBee remote control and centralized management by PC and the experimental data is ideal
