摘要
LED道路照明单灯控制器功能主要有开关、调光、监测电压电流等参数,控制器的关键技术为通信和调光技术。通过对不同的通信模式及调光方式的优缺点进行分析,本文建议单灯控制器的通信采用窄带物联网(NB-IoT)卡,并提出一种利用电子开关控制LED恒压驱动电源多组输出端的开关状态的节能调光方式。
LED(Light Emitting Diode)road lighting single lamp controller function mainly are switch,dimming,monitoring voltage,current and other parameters,among them the essential technology for the controller is the communication and the dimming technology.For the communication of LED streetlight single lamp controller,this paper suggests the use of Narrow Band Internet of things(NB-IoT)card,and presents a energy saving dimming method using electronic switch to control the switching state of multiple output channels of LED constant voltage driving power supply.
