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.
