根据路灯在不同电压下的照度及寿命特性,推导出城市道路照明灯具的最佳供电电压。通过对照明灯具从承受相电压变至线电压一半的自动转换,实现最优的照明节电模式。并且对城市道路照明节电器的节电效果进行了分析。
According to the street under different voltage illumination and life characteristics, derive the best supply voltage of urban road lighting. Through the lighting from withstand voltage to half the line voltage automatic conversion, to achieve optimal lighting power-saving mode. And the energy saving effect of the city road lighting saver is analyzed.
