Abstract

Die Erfindung betrifft einen Projektionsscheinwerfer für ein Kraftfahrzeug mit einer Lichtquelle (1), einem Hauptreflektor (2) und einer Lichtscheibe (3), wobei durch den Hauptreflektor (2) eine optische Achse (5) definiert wird.
Um die Abstrahlcharakteristik der bekannten Projektionsscheinwerfer für Kraftfahrzeuge zu verbessern und gleichzeitig ihr Erscheinungsbild gefälliger zu gestalten, wird erfindungsgemäß ein Rückreflektor (6) zwischen der Lichtquelle (1) und der Lichtscheibe (3) des Scheinwerfers angeordnet, der eine zu der optischen Achse (5) des Hauptreflektors (2) im wesentlichen zentralsymmetrische Lichtdurchtrittsöffnung (8) aufweist.
