Abstract
Ein Fahrzeugscheinwerfer weist eine Projektorleuchteneinheit auf, die zwei Arten von Lichtverteilung erzeugt. Die Leuchteneinheit ist mit einer Projektorlinse versehen, die auf einer optischen Achse angeordnet ist, die in Längsrichtung eines Fahrzeugs verläuft, und mit einer ersten Lichtquelleneinheit und einer zweiten Lichtquelleneinheit, die beide hinter der Projektorlinse angeordnet sind. Ein Abblendlicht-Lichtverteilungsmuster, das deutliche Abschneidelinien in einem oberen Endabschnitt aufweist, wird im Betrieb der ersten Lichtquelleneinheit erzeugt. Ein zusätzliches Fernlicht-Lichtverteilungsmuster, das sich von den Abschneidelinien aus nach oben ausbreitet, wird zusätzlich im Betrieb der zweiten Lichtquelleneinheit erzeugt. Auf diese Weise wird ein Fernlicht-Lichtverteilungsmuster erzeugt.
