Description

Scheinwerfer für FahrzeugeHeadlights for vehicles
Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge mit einem Tragrahmen und einer Mehrzahl von an dem Tragrahmen gehalterten Lichtquellen, wobei die Lichtquellen gruppiert ein- und ausschaltbar angeordnet sind zur Bildung eine Anzahl von Lichtfunktionen.The invention relates to a headlamp for vehicles with a support frame and a plurality of supported on the support frame light sources, the light sources grouped on and off are arranged to form a number of light functions.
Zur Grundeinstellung eines Scheinwerfers ist es bisher üblich, einen Tragrahmen, auf dem die Lichtquellen gehaltert sind, derart zu verstellen, dass auf einem Messschirm eine Hell-Dunkel-Grenze des Scheinwerfers in einem vorgesehenen Bereich verläuft. Diese Grundeinstellung kann mittels mechanischer oder elektrischer Einstellmittel bei der Montage des Scheinwerfers in der Karosserie erfolgen.For basic adjustment of a headlight, it has hitherto been customary to adjust a support frame on which the light sources are mounted in such a way that a light-dark boundary of the headlight extends in a designated area on a measuring screen. This basic adjustment can be made by means of mechanical or electrical adjustment means when mounting the headlamp in the body.
Aus der DE 40 25 392 C2 ist ein Scheinwerfereinstellgerät bekannt, mittels dessen im Rahmen einer Wartung des Scheinwerfers in Werkstätten der Scheinwerfer nacheingestellt werden kann. Dabei werden die Lichtquellen einer Lichtfunktion, wie beispielsweise der Abblendlichtfunktion, synchron um eine horizontale Achse verstellt.From DE 40 25 392 C2 a headlamp setting device is known by means of which can be readjusted in the context of maintenance of the headlamp in workshops of the headlights. In this case, the light sources of a light function, such as the low beam function, synchronously adjusted by a horizontal axis.
Aus der DE 102 05 779 A1 ist ein Scheinwerfer für Fahrzeuge bekannt, bei dem eine Mehrzahl von Lichtquellen an einem gemeinsamen Tragrahmen gehaltert sind. Die Lichtquellen sind gruppiert ein- und ausschaltbar angeordnet, so dass unterschiedliche Lichtfunktionen, wie beispielsweise Abblend-, Autobahn-, Fernlichtfunktionen einstellbar sind. Eine unabhängige räumliche Verstellung der Lichtquellen zueinander zur Erzeugung unterschiedlicher Lichtcharakteristiken bzw. Lichtfunktionen ist bei dem bekannten Scheinwerfer nicht vorgesehen. Aufgabe der vorliegenden Erfindung ist es, einen Scheinwerfer für Fahrzeuge derart weiterzubilden, dass die Grundeinstellung des Scheinwerfers bzw. die Verstellung einer Hell-Dunkel-Grenze des Scheinwerfers insbesondere bei einer Mehrzahl von Lichtquellen verbessert wird.From DE 102 05 779 A1 discloses a headlight for vehicles is known in which a plurality of light sources are mounted on a common support frame.
