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.

Abstract: A circuit for the efficient generation of high voltage pulses for the initiation of conduction in gaseous discharge lamps, the effective suppression of potentially harmful voltage surges resulting from derangement of one or more electrical, current-carrying mechanical, or mechanical components within the overall gaseous discharge lighting apparatus, and reduction of radio frequency interference resulting from the normal and deranged operation of the overall gaseous discharge lighting apparatus. The ignitor/suppressor includes a semiconductor switching device, a capacitor of special characteristics, a transformer of special construction, and a resistor for the generation of high voltage pulses. The ignitor/suppressor also includes a semiconductor switching device, a capacitor of special characteristics, and a resistor for the effective suppression of abnormally high voltages.
