荧光灯镇流器能效问题探讨

Discussion on energy efficiency of ballasts for fluorescent lamps

针对荧光灯镇流器在照明电器中的广泛应用以及总用电量中所占比重较高的现状,介绍了我国、欧盟、美国等国家荧光灯镇流器能效现状、检验标准及法律法规,从荧光灯镇流器的结构、内部元器件等方面深入分析了荧光灯镇流器产生不必要的能源损耗和降低荧光灯寿命的主要原因,提出了提高荧光灯镇流器能源效率所涉及的设计、制造等方面的具体措施和荧光灯镇流器的发展趋势。研究结果表明,荧光灯镇流器的节能是一项系统工程,要从整个照明系统综合考虑其节能效果。

Aiming at wide application of ballasts for fluorescent lamps in lighting electrical appliance and the high proportion in total power consumption,the energy efficiency,test standard,laws and regulations of ballasts for fluorescent lamps of European Union,United States and China were introduced,from the structure and internal electronic devices,the main causes of the unnecessary energy loss of ballasts for fluorescent lamps were analyzed and the life of fluorescent lamps was reduced,the technical innovation concerning design and manufacture of high efficient ballasts for fluorescent lamps were proposed,the development trend of ballasts for fluorescent lamps was discussed.The results indicate that ballasts for fluorescent lamps＇ energy saving is a systematic project,so the effect of energy saving measures should be considered from the perspective of whole lighting system.
