Abstract

A lens bracket for accommodating a lens in a headlamp and a headlamp having a lens bracket of this type, said headlamp being formed substantially by a housing made of a base body and a lens cover, and wherein the lens bracket is designed as a plastic body. It is inventively provided that the plastic body has a metal surface element which is designed in such a manner that the plastic body is protected from radiation incoming into the housing through the lens cover and entering through the lens.

Claims

1. A lens bracket for accommodating a lens in a headlamp, said headlamp being formed substantially by a housing made of a base body and a lens cover, comprising:

a plastic body forming a portion of said lens bracket and having a metal surface element configured to protect said plastic body from radiation incoming through said lens cover and entering through said lens;

said plastic body further comprising an opening region in an interior thereof in which said lens is accommodated, wherein said metal surface element is arranged on an inner side of said plastic body facing said opening region; and

wherein said plastic body has a section surrounding said opening region on an underside of said plastic body, wherein said metal surface element is arranged on the inner side of the section on said underside.

2. The lens bracket according to claim 1, wherein said plastic body is configured as a freeform body with a freeform contour, and wherein said metal surface element is configured with a freeform body corresponding to said freeform contour of said plastic body.

3. The lens bracket according to claim 1, characterized in that said plastic body is injection molded, and wherein said plastic body is injected onto said metal surface element.

4. The lens bracket according to claim 1, wherein said metal surface element is glued, snapped in, or connected, by means of a connecting means, with said plastic body, to an inner side of said plastic body.

5. The lens bracket according to claim 1, wherein said metal surface element is configured as a film or as a dimensionally stable metal body.

6. A headlamp having a lens bracket for accommodating a lens, comprising:

a housing that is substantially formed of a base body and a lens cover, and wherein the lens bracket is incorporated in the housing and comprises a plastic body;

a metal surface element in said plastic body configured to protect said plastic body from radiation incoming into said housing through said lens cover and entering through said lens;

wherein said plastic body further comprises an opening region in an interior thereof and in which said lens is accommodated, wherein said metal surface element is arranged on an inner side of said plastic body facing said opening region; and

wherein said plastic body has a section surrounding said opening region on an underside of said plastic body, wherein said metal surface element is arranged on the inner side of the section on said underside.

7. The headlamp according to claim 6, wherein said plastic body is configured as a freeform body with a freeform contour, and wherein said metal surface element is configured with a freeform body corresponding to said freeform contour of said plastic body.

8. The headlamp according to claim 6, characterized in that said plastic body is injection molded, and wherein said plastic body is injected onto said metal surface element.

9. The headlamp according to claim 6, wherein said metal surface element is glued, snapped in, or connected, by means of a connecting means, with said plastic body, to an inner side of said plastic body.

10. The headlamp according to claim 6, wherein said metal surface element is configured as a film or as a dimensionally stable metal body.
