Abstract

Vorgestellt wird ein Kraftfahrzeugscheinwerfer (1) mit einer matrixartigen Anordnung von Halbleiterlichtquellen (13, 14, 15, 16), eine Primäroptik (3) und einer Sekundäroptik (4). Die Primäroptik weist eine Grenzfläche (25) mit einer mittleren Zeile (34) auf, die sich aus wenigstens drei Lichtaustrittsbereichen (36, 38, 40) zusammensetzt. Die Sekundäroptik (4) ist dazu eingerichtet, eine sich auf der Grenzfläche (25) einstellende Lichtverteilung abzubilden. Der Scheinwerfer zeichnet sich dadurch aus, dass sich die Lichtaustrittsflächen der mittleren Zeile (34) in ihrer Form von den Lichtaustrittsflächen einer benachbarten Zeile (44, 46) unterscheiden, wobei ein mittlerer Lichtaustrittsbereich (55) der mittleren Zeile (34) durch zwei V-förmig aufeinander zulaufende Kanten (53, 54) von den benachbarten Lichtaustrittsbereichen der mittleren Zeile (34) getrennt ist.

Figure imgaf001
Disclosed is a motor vehicle headlight (1) with a matrix-like arrangement of semiconductor light sources (13, 14, 15, 16), a primary optic (3) and a secondary optics (4). The primary optic has an interface (25) with a central line (34), which consists of at least three light exit areas (36, 38, 40). The secondary optics (4) is set up to image a light distribution that occurs on the interface (25). The headlamp is characterized in that the light exit surfaces of the central line (34) differ in their shape from the light exit surfaces of an adjacent line (44, 46), wherein a central light exit region (55) of the middle line (34) by two V shaped converging edges (53, 54) is separated from the adjacent light exit areas of the middle line (34).
