The Derivation of Fluorescent Lamp System Model and Calculation of its Key Parameters

在高效节能理念深入工业设计的今天,作为节能照明先驱的荧光灯发挥了不可替代的作用。但目前来讲,荧光灯设计复杂、关键参数选择困难、理论推导结果与实物测试差异较大。针对此,本文根据荧光灯启动特性,推导出了一种荧光灯的启动电路模型,从理论上给出了其关键元器件参数、工作点频率等的计算方法。通过带普通T8荧光灯灯管实验,将该模型用于电子镇流器设计,验证了理论模型的正确性和实用性。

Nowadays efficient concepts have had deep effects in industrial design,as the pioneer of energysaving,fluorescent lamp lighting played an irreplaceable role.But complexity of fluorescent lamp electric circuit design,difficulty of the key parameters choosing,the differentia between theoretical results and physical test make fluorescent lamp circuit design difficult.The paper gives a start-circuit model based on the fluorescent lamp characteristics,the calculation of the key components＇ parameters and operating point frequency in theory.With a normal T8 fluorescent lamp through the experiment which used the given model in electronic ballast design,the theoretical model is proved to be correct and practical.
