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).
