An energy-saving control system of campus lighting based on LED is presented,which includes constant current LED driving module,light intensity detection module,pyroelectric infrared sensing module,counting module and GPRS wire-less communication module. The 18 W T8 LED tube lamps and 50 W panel LED lamps are mainly used in the system to replace the traditional fluorescent lamps in the classrooms and the street lamps along the campus roads respectively. The versatility of driving module can work with two kinds of DC input voltage of 12 V and 24 V. The maximum output power of the driving module is up to 150 W and the output voltage is adaptive so that it can be compatible with a variety of LED lamps in parallel or serial connection. The system is also suitable for museums,large hotels,underground parking and other places where need large quan-tity of energy.%设计了一套适用于高校校园的LED照明节能控制系统，包括LED恒流驱动电源、光照度检测模块、红外热释电传感模块、计数模块和GPRS无线通信模块等。配套了18 W T8型LED灯管和50 W面板型两种LED灯具，分别用于替换教室荧光灯和校园道路路灯。驱动电源通用性好，支持12 V和24 V两种直流输入电压，最大输出功率可达150 W，且输出电压自适应，使其能够兼容多种串并方式的LED灯具。该系统同样适用于博物馆、大型酒店、地下停车场等照明需求量大的应用场合。
