摘　　要：根据高压钠灯在不同电压下的照度及寿命特性,推导出路灯半夜灯的最佳供电电压。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,实现高压钠灯供电电压的优化,从而实现照明节电。Based on the illumination and lifetime characteristics of street lights under different supply voltage, the best voltage supply for high-pressure Sodium lamps used in city street lighting is derived. By automatic transformation from the bearable phase voltage to a half of the line voltage, the optimized power supply voltage of high-pressure Sodium lamps is realized. The method can be applied in saving energy mode for urban street lighting.
