Preheating Model of Fluorescent Lamp Based on Verilog-A

提出了基于Verilog-A的荧光灯预热模型。该模型表示荧光灯管预热过程中灯丝热电阻与预热前灯丝冷电阻之比Rh/Rc的精确值。使用该模型能够方便地设计带预热功能的电子镇流器相关参数。实验过程及结果表明,该方法不但节约了设计时间,而且能够使得荧光灯预热达到最佳状态,使用寿命尽可能长。

The preheating model of fluorescent lamps based on Verilog-A was presented. The model showed the accurate value of the Rh/Rc in the preheating process. The correlative parameters of electronic ballasts with preheating capalities can be designed conveniently according to this model. The process and the results of the experiment showed that this way not only saved time, but also made the preheating state of the fluorescent lamps achieve optimization, and made the life of fluorescent lamps as long as possible.
