Abstract

Um auch Leuchtstofflampen mit erhöhter Zündspannung (z.B. Lampen mit 26 mm Durchmesser) mit einer üblichen Dim­ merschaltung in ihrer Helligkeit steuern zu können, wird die zu­ sätzliche Anordnung eines Zündgerätes (6) vorgeschlagen, das mit dem Anstieg der angeschnittenen Wechselspannung synchronisierte Zündimpulse liefert. Das Zündgerät (6) ist ein­ gangsseitig mit den Ausgängen eines Dimmers (1) verbunden und ausgangsseitig mit den Elektroden (9) einer Leuchtstoff­ lampe (7). To also fluorescent lamps with increased ignition voltage (e.g. lamps with a diameter of 26 mm) with a common dim To be able to control the brightness of the switching circuit becomes too proposed additional arrangement of an ignition device (6), that with the increase in the cut alternating voltage delivers synchronized ignition pulses. The ignitor (6) is a connected on the output side to the outputs of a dimmer (1) and on the output side with the electrodes (9) of a phosphor lamp (7).
