Abstract

Es wird eine Schaltung zur Ansteuerung mehrerer in Reihe geschalteter Leuchtmittel vorgeschlagen, umfassend mehrere elektronische Schalter, die in Abhängigkeit von einer gleichgerichteten Netzspannung ansteuerbar sind, wobei die mehreren elektronischen Schalter parallel zu mindestens einem Teil der Leuchtmittel angeordnet sind, wobei jeder der mehreren elektronischen Schalter bei Aktivierung jeweils mindestens eines der in Reihe geschalteten Leuchtmittel kurzschließt, mit mindestens einem Energiespeicher, der während einer Ladephase anhand der elektronischen Schalter parallel zu einer ersten Gruppe von Leuchtmitteln geschaltet ist und der während einer Entladephase anhand der elektronischen Schalter parallel zu einer zweiten Gruppe von Leuchtmitteln geschaltet ist.
