摘　　要：LED路灯恒流源是LED路灯照明设计的关键,而具有灯光自动调节、通信等智能控制功能的LED路灯恒流源将会推动LED路灯照明的快速发展。智能数字恒流源系统融合了基于HV9110B芯片控制的Buck电路、单片机中心控制单元以及通信单元,能够实现LED路灯根据外界自然光和自身温度自动调光,恒流源高精度的电流输出,供电电源和LED路灯恒流源之间的通信和检测调试等功能。设计了智能数字恒流源系统的总体电路结构,各部分的电路设计,通信单元的软件设计,控制故障显示界面设计。实验结果表明该系统满足设计和应用要求。Constant-current source of LED street lights is the key design to the LED street lamp lighting system. The constant-current source with functions of automatic adjustment, communication and other intelligent control will promote the rapid development of LED street lamp lighting. Intelligent digital constant-current source system combines the Buck circuit based on HV9110 B unit,single chip microcomputer center control unit and communication unit, can achieve the following functions： LED street lamp automatic dimmer according to the outside natural light and its temperature,high precision output current,communication and testing debugging between power supply and LED street lamps and so on. The overall circuit structure of the intelligent digital constant-current source system was designed, each part circuit, software of communication unit and the control and fault display interface were also designed. The experimental results show that this system satisfies the requirement of design and application.
