摘要
提出一种基于PIC16F877A为控制核心的太阳能与市电互补LED照明系统。介绍系统的组成和工作原理、系统控制器和直流LED负载,分析了系统的工作状态和程序控制流程。结合现有小区草坪灯、路灯的实际供电情况,提出了太阳能和市电互补照明的设计思想,在实际中具有良好开发和应用前景。
In this paper an LED illumination system based on PIC16F877A as its control core and using solar cell complemented by commercial power is presented.The system compositions,working principle,system controller and dc LED load are introduced,the working states of the system and the program control flow are analysed as well.Based on actual power supply condition at present for streetlights and lawn lights in residence districts,a design idea of solar cell complemented by commercial power is presented.The system has good practical development and application prospects.
