摘　　要：照明路灯通过自藕变压器进行调零切换实现有级降压,可以得到不同的节电效果。按照人们对节电量的不同要求,提出了根据电网电压的变化采用模糊控制的方法实现路灯的节电控制。实验证明,该方法使电光源的工作电压基本保持在所要求的节电等级的电压范围内。Using of change on neutral point for auto-transformer to achieve tap change by step, lighting lamps can have different effects of power-saving. According to different requirements of people on the rate of power-saving, this paper has proposed an fuzzy control method to power-saving of lighting lamps , based on the power voltage changes. Experimental result shows that the method makes the operating voltage of electric-light source maintained at the range required voltage level of power saving.
