ABSTRACT
Vinpm : minimum peak value of AC output current linp the maximum peak value of AC input current. According to the plan above, we can make the luminous flux of the electromagnetic induction lamp changed between the range of 30%—l00%. it gets very good result. 4.Conclusion: The LVD induction lamp light dimming plan above use the rules of dimming by the adjustment of frequency. Enable the LVD induction lamp dimming function as same as incandescent lamps. Fulfilled the objective of linear light dimming with the LVD induction lamp tubes. The research and development of this project fully supported by Doctor Dahua Chen in Shanghai Fudan university, it will make great contribution and lays a foundation for further development of the electromagnetic induction lamps in the future.
