Abstract

Die Erfindung betrifft eine Schaltungsanordnung zum Betreiben einer Beleuchtungseinrichtung, insbesondere eines LED-Signalgebers (9), im Zusammenwirken mit einer übergeordneten Einrichtung, insbesondere einer Überwachungseinrichtung, die einen Einschaltstrom vorgibt. Um eine für die Strom-Zeit-Charakteristik einer Glühlampe konzipierte übergeordneten Einrichtung, insbesondere Überwachungseinrichtung, auch für eine andere Beleuchtungseinrichtung verwenden zu können, ist ein Schaltungsteil vorgesehen, der einen Einschaltstrom bis oberhalb einer Ansprechschwelle der Überwachungseinrichtung während einer Zeitdauer (ΔtL) einstellt.

The invention relates to a circuit arrangement for operating a lighting device, in particular an LED signal generator (9), in cooperation with a higher-level device, in particular a monitoring device, which specifies an inrush current. In order to be able to use a higher-level device designed for the current-time characteristic of an incandescent lamp, in particular monitoring device, for another illumination device, a circuit part is provided which adjusts an inrush current to above a threshold of the monitoring device during a period of time (.DELTA.t L ).
