Abstract

Bei Scheinwerfern von Kraftfahrzeugen ist das Leuchtmittel (1) in einem Leuchtengehäuse hinter einer Lichtscheibe angeordnet. Das vom Leuchtmittel (1) ausgesandte Licht wird an einem Reflektor (4) zur Lichtscheibe reflektiert. Um bei geringer Bauhöhe eine größtmögliche Leuchtfläche zu erreichen, wird die Reflektorfläche (6) durch eine Rotationsfläche gebildet, deren Erzeugende Teil einer Kurve ist. Die Rotationsfläche (6) verläuft in Richtung auf das Leuchtmittel (1) ansteigend, das gegen die Reflektorfläche (6) gerichtet ist. Das Leuchtmittel (1) kann nahe an der Reflektorfläche (6) angeordnet werden. Der Reflektor wird für Leuchten von Kraftfahrzeugen eingesetzt.

Figure 00000001
In headlamps of motor vehicles, the lighting means (1) is arranged in a luminaire housing behind a lens. The light emitted by the light source (1) is reflected at a reflector (4) to the lens. In order to achieve the greatest possible luminous area at low height, the reflector surface (6) is formed by a surface of revolution whose generatrix is part of a curve. The rotation surface (6) extends in the direction of the lighting means (1) rising, which is directed against the reflector surface (6). The lighting means (1) can be arranged close to the reflector surface (6). The reflector is used for lights of motor vehicles.
