Abstract

Die Erfindung betrifft eine elektrische Schaltungsanordnung für eine Kfz-Leuchte mit Leuchtdioden (31, 32). Dabei weist die Schaltungsanordnung zwei Versorgungsanschlüsse, eine Widerstandsschaltung (1), eine Diodenschaltung (2) und eine oder mehrere Leuchtdioden (31, 32) auf.
Eine derartige Schaltungsanordnung ist so verbessert, dass die Eingänge der Widerstandsschaltung (1) unmittelbar mit den Versorgungsanschlüssen verbunden ist, dass mit den Ausgängen der Widerstandsschaltung (1) die Eingänge (25, 26) der Diodenschaltung (2) verbunden sind und dass die vorzugsweise in Reihe geschalteten Leuchtdioden (31, 32) an die Ausgänge der Diodenschaltung (2) angeschlossen sind.

The invention relates to an electrical circuit arrangement for a motor vehicle light with light emitting diodes (31, 32). In this case, the circuit arrangement has two supply connections, a resistance circuit (1), a diode circuit (2) and one or more light-emitting diodes (31, 32).
Such a circuit arrangement is improved so that the inputs of the resistance circuit (1) is directly connected to the supply terminals, that the inputs (25, 26) of the diode circuit (2) are connected to the outputs of the resistance circuit (1) and that preferably in Row of light emitting diodes (31, 32) are connected to the outputs of the diode circuit (2).
