Buffer gas and driving frequency dependence in a low-frequency driven electrodeless compact fluorescent lamp

Abstract

Considering the point of cost, the driving frequency of the electrodeless discharge lamp should be lowered because high frequency driving (> 1MHz) requires special components for reduction of noise and circuit loss. It is, however difficult to obtain enough electric field to maintain a discharge at low power, therefore it is needed to improve the bulb which enables to maintain a stable discharge.
We investigated the buffer gas condition and driving frequency to cope with maintenance of plasma, so as to realize the low-frequency driven (<480kHz) and low power (<12W, which replaces for 60W incandescent lamp) electrodeless compact fluorescent lamp.
