Abstract
An electronic circuit is shown to initiate and sustain conduction in a gaseous discharge light. A breakover device and snubber network, isolation network, and self-adjusting symmetrical high voltage pulse generator are incorporated into a standard gaseous discharge light assembly typically composed of a power source, gaseous discharge lamp ballast apparatus, and gaseous discharge lamp. The electronic circuit is used (1) for initiating and sustaining conduction of electrical current through gaseous discharge lamps, (2) to provide active suppression of transient voltages both within and external to the gaseous discharge lighting apparatus, and (3) to provide significant attenuation of the propagation of undesirable conducted and radiated radio frequency interference from the gaseous discharge lamp and the overall associated ballast apparatus.
