摘要
LED路灯的广泛推广对节能减排有重要意义。在分析LED光源驱动特性的基础上,设计了一种基于单片机控制的路灯智能驱动系统,并详细介绍了关键单元的实现过程,同时,提出了一种LED路灯节能控制方法;本系统充分考虑了外部光照、工作温度等外部条件变化,体现了LED路灯照明系统的自适应性,达到最佳的利用效果,并且节约了能源,优化了LED路灯系统的照明效率。
Street lighting based light emitting diode （LED） with high efficacy has great potentials for energy savings. Considering the properties of the LED, a driving controller for intelligent street lighting application was designed and the detailed driving circuit principle was given. The proposed method made full use of the external working conditions such as temperature and had strongly capability to meet the needs of further energy savings.
