Abstract

Vorgestellt wird ein Lichtmodul (14) eines Kraftfahrzeugscheinwerfers, mit mehreren Lichtquellen (28), einer Primäroptik (30) und einer Sekundäroptik (12), wobei die Primäroptik (30) dazu eingerichtet ist, von den Lichtquellen ausgehendes Licht zu sammeln und in eine Zwischenlichtverteilung (68) zu überführen, welche die Form einer geschlossen leuchtenden Fläche aufweist, und wobei die Sekundäroptik (12) eine objektseitige Brennweite aufweist, wobei die Primäroptik und die Sekundäroptik so angeordnet sind, dass die Zwischenlichtverteilung im Abstand dieser Brennweite im Lichtweg vor der Sekundäroptik liegt. Das Lichtmodul zeichnet sich dadurch aus, dass die Lichtaustrittsflächen der Lichtquellen (28) durch zwischen ihnen liegende Abstände voneinander getrennt sind und dass die Primäroptik (30) dazu eingerichtet ist, von den Lichtquellen ausgehendes Licht so zu verteilen, dass die Abstände in der Zwischenlichtverteilung (68) nicht erkennbar sind.
