Abstract

A motor-vehicle headlight, e.g., a front headlight, having a lighting unit, which includes a light source, a reflector surrounding the light source, and a lens device. The reflector essentially reflects the light emitted by the light source, in the direction of the lens device. The headlight includes a housing, which accommodates the lighting unit, and on which a transparent headlight cover is arranged. A light-deflection device or a prepared mounting location for the light-deflection device is provided, which transmits scattered light emitted by the light source to an optical-system part, which is arranged or attachable at essentially any location in the housing.

Claims

1. A motor-vehicle headlight, comprising:

a lighting unit including a light source, a reflector surrounding the light source and a lens, the reflector arranged to focus light emitted by the light source in a direction of the lens;

a housing arranged to accommodate the lighting unit;

a transparent headlight cover arranged on the housing; and

one of (a) a light-deflection device and (b) a prepared mounting location for the light-deflection device arranged to transmit scattered light emitted by the light source to an optical-system part one of (a) arranged and (b) attachable at substantially any location in the housing.

2. The motor-vehicle headlight according to claim 1, wherein the light-deflection device is arranged between the lens and one of (a) the reflector and (b) a main part of the reflector at a radial distance from an optical axis of the lighting unit.

3. The motor-vehicle headlight according to claim 1, wherein the light-deflection device is arranged as a reflector.

4. The motor-vehicle headlight according to claim 1, wherein the light-deflection device is arranged as a light-guide device.

5. The motor-vehicle headlight according to claim 1, wherein the optical-system part is arranged behind the reflector in an illumination direction of the motor-vehicle headlight.

6. The motor-vehicle headlight according to claim 1, wherein the optical-system part includes a diffusely reflective surface.

7. The motor-vehicle headlight according to claim 1, wherein the optical-system part is arranged as a part of one of (a) the lighting unit and (b) the housing.

8. The motor-vehicle headlight according to claim 7, wherein the optical-system part is arranged as a part of one of (a) a cover frame and (b) a reflector surface.

9. The motor-vehicle headlight according to claim 1, wherein the optical-system part includes optical elements configured to at least one of (a) refract and (b) deflect the light.

10. The motor-vehicle headlight according to claim 1, wherein the optical-system part includes at least one emblem arranged to be illuminated by diffuse incident light.

11. The motor-vehicle headlight according to claim 1, wherein the optical-system part is made of heat-resistant and transparent plastic.

12. The motor-vehicle headlight according to claim 1, wherein the optical-system part is made of acrylic glass.

13. The motor-vehicle headlight according to claim 1, wherein the optical-system part is arranged to produce a clearly defined night design.

14. The motor-vehicle headlight according to claim 1, wherein the motor-vehicle headlight corresponds to a front headlight.

16. The motor-vehicle headlight according to claim 1, wherein the light-deflection device is arranged between one of (a) the lens and (b) the transparent headlight cover and one of (a) the reflector and (b) a main part of the reflector at a radial distance from an optical axis of the lighting unit.

15. A motor-vehicle headlight, comprising:

lighting means including light source means, reflector means surrounding the light source means and lens means, the reflector means for focusing light emitted by the light source means in a direction of the lens means;

housing means for accommodating the lighting means;

transparent headlight cover means arranged on the housing means; and

one of (a) a light-deflection means and (b) a prepared mounting means for the light-deflection device means for transmitting scattered light emitted by the light source means to an optical-system means one of (a) arranged and (b) attachable at substantially any location in the housing means.
