Abstract

The present invention relates to a lens arrangement (7) for a motor vehicle headlight (7) or a motor vehicle light having at least one light source (5.1, 5.2, 5.3) that in the switched-on state emits light, the lens arrangement (7) including a plurality of individual lenses (7.1, 7.2, 7.3) that are arranged in the beam path of the light. In order to be able to manufacture and assemble the lens arrangement (7) as simply and as cost-effectively as possible, and so that the lens arrangement has the most reserved appearance possible, the present invention proposes that a light-emitting surface (7.4) of the lens arrangement (7) have a constant curvature. Advantageously, the curvature of the light-emitting surface (7.4) has no points of inflection. A light-receiving surface (7.5) of the lens arrangement (7) is advantageously configured such that, in combination with the light-emitting surface (7.4), specifiable projection characteristics of the individual lenses (7.1, 7.2, 7.3) result.

Claims

1-12. -12. (canceled)

13. A lens arrangement (7) for a motor vehicle headlight (1) or for a motor vehicle light having at least one light source (5.1, 5.2, 5.3) that in the switched-on state emits light, the lens arrangement (7) including a plurality of individual lenses (7.1, 7.2, 7.3) that are arranged in the beam path of the light, wherein a light-emitting surface (7.4) of the lens arrangement (7) has a constant curvature.

14. The lens arrangement (7) as recited in claim 13, wherein the curvature of the light-emitting surface (7.4) has no points of inflection.

15. The lens arrangement (7) as recited in claim 13 wherein a light-receiving surface (7.5) of the lens arrangement (7) is configured such that, in combination with the light-emitting surface (7.4), specifiable projection characteristics of the individual lenses (7.1, 7.2, 7.3) result.

16. The lens arrangement (7) as recited in any of claim 13, wherein any and all patterns (8.1, 8.2) may be applied to the light-emitting surface (7.4) or may be introduced into the light-emitting surface (7.4).

17. The lens arrangement (7) as recited in any of claim 13, wherein a plurality of light sources (5.1, 5.2, 5.3) of the headlight (1) or light are assigned to the individual lenses (7.1, 7.2, 7.3) of the lens arrangement (7).

18. The lens arrangement (7) as recited in claim 17, wherein different types of light sources (5.1, 5.2, 5.3) are assigned to the individual lenses (7.1, 7.2, 7.3).

19. The lens arrangement (7) as recited in claim 17, wherein each of the individual lenses (7.1, 7.2, 7.3) is assigned its own light source (5.1, 5.2, 5.3).

20. The lens arrangement (7) as recited in any of claim 13, wherein a plurality of reflectors (6.1, 6.2) of the headlight (1) or light are assigned to the individual lenses (7.1, 7.2, 7.3).

21. The lens arrangement (7) as recited in claim 20, wherein each of the individual lenses (7.1, 7.2, 7.3) is assigned its own reflector (6.1, 6.2).

22. The lens arrangement (7) as recited in any of claim 13, wherein the lens arrangement (7) is configured as a cover disk of the headlight (1) or light.

23. A motor vehicle headlight (1) having at least one light source (5.1, 5.2, 5.3) that in the switched-on state emits light and having a lens arrangement (7) which includes a plurality of individual lenses (7.1, 7.2, 7.3) that are arranged in the beam path of the light, wherein the lens arrangement (7) has a constant curvature.
