Abstract

A starting and operating device for controlling a starter that ignites a sodium lamp, AC power voltage being provided to the starter and sodium lamp by means of a power supply transformer having its secondary winding connected to the starter and sodium lamp, and its primary winding connected to an AC power source. The device comprises an AC/DC converter connected to the primary winding for converting AC voltage into a low DC voltage; a high power disabling device for disabling the starter; an optor-isolator connected to the high power disabling device for controlling the high power disabling device by means of a low DC signal, and for electrically isolating the high power disabling device; a timer connected to the opto-isolator for generating the low DC signal after passage of a predetermined amount of time to disable the starter; and a first delay circuit connected to the AC/DC converter for detecting energizing of the AC/DC converter, and for generating a delayed resetting signal for the timer after detection of the energizing whereby the AC/DC converter can be stabilized before resetting the timer.
