ABSTRACT:
A method and apparatus for ionizing a rare gas in a gas type cold cathode lighting source using a high voltage direct current pulse. Direct current pulses are applied to the lighting source, the current flow to the lighting source is sensed, upon ionization of the gas the voltage level of the pulse is reduced and the pulse width is increased so as to provide a proportionally increased constant current high voltage direct current pulsed output, and the polarity of the pulses to the light source is periodically reversed.
