ABSTRACT:
An electronic starter for a discharge lamp includes an SCR controlled by a temperature-sensitive element and an auxiliary switch arranged so that no current flows in the temperature-sensitive element when the lamp is in operation, whereby rapid restarting of the lamp occurs after a brief interruption of the AC supply voltage. The temperature-sensitive element may be thermally coupled to an inductor in series with the lamp ballast thereby to limit the ballast current in the event the lamp fails to ignite.
