Abstract

Das Vorschaltgerät weist einen Reihenschwingkreis (17, 18) auf, dessem Kondensator (18) die Leuchtstofflampe (14) parallelgeschaltet ist. Die Stromzufuhr zu dem Reihen­ schwingkreis (17, 18) erfolgt über eine Spule (22) unter Steuerung durch ein einziges elektronisches Schaltelement (21), das in Abhängigkeit von dem Schwingkreisstrom geöffnet und gesperrt wird. The ballast has a series resonant circuit (17, 18) on whose capacitor (18) the fluorescent lamp (14) is connected in parallel. The power supply to the rows resonant circuit (17, 18) takes place via a coil (22) Controlled by a single electronic switching element (21) which is dependent on the resonant circuit current is opened and locked.
