ABSTRACT:
A high-pressure discharge lamp has a starting circuit consisting of a bimetallic switch and a resistor, which is connected in parallel with the arc tube, and is turned on via a mercury lamp ballast. The current which flows into the starting circuit is limited by the current that flows into the arc tube and by the output of the ballast. Therefore, the extinguishing voltage phenomenon that hitherto had developed immediately after the lamp was turned on no longer takes place.
