On the Effects of Frequency on Fluorescent Lamp Starting

Abstract

Many factors affect fluorescent lamp starting. The frequency of applied voltage is one of them. The effect of frequency is attributable to the changes of potential distribution along the tube surface and the voltage drop at the tube end.Analysing the above changes, with the aid of an equivalent circuit, it has become now clear that:(1) At lower tube surface resistances, the starting potential increases as the frequency increases.(2) At higher tube surface resistances, it decreases as the frequency increases.(3) Sometimes, the starting potential shows maximum value at certain frequencies. Above facts are also proved by our experiments.
