摘要
根据路灯在不同电压下的光电参数及寿命特性,推导出城市道路照明灯具的最佳供电电压:上半夜为额定电压220 V,下半夜为节能电压200 V,介绍了几种节能电压实现方案。
According to the street lamp of the light electricity parameter and the life characteristic, in different voltage a best supply voltage of urban road lighting systems lighting luminaire is deduced： a rated voltage is 220 V in the first half of the night, and the best voltage is 200 V in the later half of the night.
