Abstract: 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.
Key words: ballasts for fluorescent lamps ; laws and regulations ; energy efficiency
