摘　　要：设计了一种采用低成本TL431等电子器件的新型控制器,具有过充电、过放电保护、LED准恒流控制等功能,并可根据亮度自动启动和关闭LED路灯。实验表明:该控制器不仅能够满足LED路灯的控制要求,而且运行可靠、成本低廉、维修方便,具有极高的推广价值。This paper designs a new kind of low-cost controller using TL431 and other electronic devices, which has the functions of over charge, over discharge protection, automatic startup and shutdown according to the brightness and LED quasi-constant current control. The experiments indicate that the controller runs reliably, costs lowly, and is convenient to repair. It can meet the requirements of LED street light control and has a promising market in the future.
