Abstract

Die vorliegende Erfindung bezieht sich auf eine Beleuchtungseinrichtung für ein Kraftfahrzeug, umfassend zumindest eine an ein Kfz-Bordnetz anschließbare Steuereinrichtung (1), an der LED-Anordnungen (2) anschließbar und betreibbar sind. Um den Schaltungsaufbau zu vereinfachen und eine verbesserte Funktionalität zu gewährleisten, wird erfindungsgemäß vorgeschlagen, dass die Steuereinrichtung als Lichtsteuermodul (1) ausgebildet ist mit einem Gleichspannungswandler (4) zur Umsetzung der Kfz-Bordnetzspannung in eine konstante LED-Betriebsspannung zur Ansteuerung der LED-Anordnungen (2).

The present invention relates to a lighting device for a motor vehicle, comprising at least one connectable to a motor vehicle electrical system control device (1) to the LED assemblies (2) can be connected and operated. In order to simplify the circuit structure and to ensure improved functionality, the invention proposes that the control device is designed as a light control module (1) with a DC-DC converter (4) for converting the vehicle electrical system voltage into a constant LED operating voltage for driving the LED arrays (2).
