荧光灯管运行时的外部交流驱动电路和内部直流电路(上)

The External AC Driving Circuit and the Internal DC Electron Circuit of Operating Fluorescent Tubes(Ⅰ)

通过对外电极荧光灯(EEFL)的检测发现,在荧光灯管(FL)运行时,两种完全不同的电路(外部AC驱动电路和内部DC电路)并存且合为一体。外部AC驱动电路决定了FL管运行的基本AC功耗,并且仅有内部DC电路决定FL管的亮度。通常所说的FL管的功耗是外部驱动装置的AC功耗,它并不介入FL管运行时的汞原子激发。

By examining the external electrode fluorescent lamp（EEFL）,we have revealed the disparate electric circuits（external AC driving circuit and internal DC electron circuit） which coexist in the operation of the fluorescent lamp（FL） tubes as unit.The external AC driving circuit determines the substantial AC power consumptions for operation of the FL tubes,and the internal DC electron circuit exclusively determines the luminance of the FL tubes.The traditional power consumption of the FL tubes is the AC power consumption of the external AC driving device which does not involved in the excitation of Hg atoms in the operation of the FL tubes.
