摘　　要：为充分体现低压钠灯光效高的特点,同时又保证低压钠灯与电子镇流器组成的系统效率最高,对该系统进行了深入研究。经理论分析,低压钠灯的光效与电子镇流器的效率均随频率变化明显,而且变化趋势恰好相反,存在一最佳工作频率使系统效率最高。以24V直流输入电子镇流器与55W低压钠灯组成的系统为实验平台,通过对低压钠灯光通量输出与电子镇流器电功率输入的测量,分析了系统效率与镇流条件的关系。实验结果表明,系统的效率随频率的变化而变化,合适的镇流条件可使系统的效率最高。To fully incarnate the characteristic of the high luminous efficiency of the low pressure sodium lamp（LPS）and to optimize the efficiency of the system which is made up of the LPS and the electronic ballast,a detailed research on the system has been done.Theoretically,the luminous efficiency of the LPS and the efficiency of the electronic ballast are both vary obviously with the work frequency of the LPS,and the trend is opposite,it means there is a frequency point which can optimize the efficiency of the system.The researched system is composed of the ballast with the input is 24 V and 55 W,by measuring the luminous flux of the LPS and the input power of the ballast,the relation between the efficiency of the system and the ballast conditions is analysed.The experimental results show that the proper ballast technologies can optimize the efficiency of the system.
