Motor vehicle headlamp having a multi-function projection module

1. A motor vehicle headlamp having a multi-function projection module, said headlamp comprising:

a first light source, a first primary lens system, a second light source, a second primary lens system, an aperture having an aperture edge, a projection lens having an optical axis, and a mirror being reflective, and wherein each of the first and second light sources is oriented to face the projection lens;

the first primary lens system being configured to transfer light of the first light source in a first beam-path being restricted by the aperture edge such that the first-beam path is restricted to be above the optical axis and into a first light distribution area located in front of the projection module;

the second primary lens system being configured to focus light of the second light source in a second beam-path into a beam waist and to transfer the light into a second light distribution area located in front of the projection module;

the second light distribution area includes a predetermined central point, which when the headlamp is used according to its intended purpose, lies at an intersection point of a horizontal line H=0 and a vertical line V=0 in front of the vehicle in the manner predetermined by the lighting standards for motor vehicles; and

wherein the mirror is arranged in the second beam path such that the mirror is configured to reflect the light in second beam path such that the second beam path is restricted to be below the optical axis and wherein the mirror is disposed between the beam waist and the projection lens such that the mirror is configured to generate a virtual reflection of the beam waist that surrounds the predetermined central point of the second light distribution area through an image conveyed by the projection lens.

2. The motor vehicle headlamp as set forth in claim 1 wherein the mirror extends beyond a Petzval surface of the projection lens over a particular length in a space situated between the Petzval surface and the projection lens, which length is greater than half (f/2) the focal length (f) of the projection lens.

3. The motor vehicle headlamp as set forth in claim 1 wherein when used according to its intended purpose the mirror lies below the aperture edge of the aperture.

4. The motor vehicle headlamp as set forth in claim 2 wherein the aperture edge is arranged at a distance from the projection lens corresponding to a focal length (f) of the projection lens.

5. The motor vehicle headlamp as set forth in claim 1 wherein a rear surface of the mirror comprises at least one of a light-diffusing coating, a light-diffusing structure, and a scattering structure, designed to reflect incident light of the first light source on the projection lens in such a way that it is refracted by the projection lens as defined overhead illumination into a dark portion of the first light distribution area.

6. The motor vehicle headlamp as set forth in claim 1 wherein the aperture is implemented in the form of a mirror shutter which extends starting from the aperture edge into a space situated between the aperture edge and the first primary lens system, and which is arranged to reflect incident light on the projection lens in such a way that it is refracted by the projection lens in a light portion of the first light distribution area.

7. The motor vehicle headlamp as set forth in claim 1 wherein the mirror is designed in the form of a mirrored metallic surface and forms an integrally molded component together with the aperture.

8. The motor vehicle headlamp as set forth in claim 1 wherein the mirror is a boundary surface of a light conductor.

9. The motor vehicle headlamp as set forth in claim 8 wherein the light conductor is implemented as an integral part of the second primary lens system.

10. The motor vehicle headlamp as set forth in claim 8 wherein the mirror shutter is a component that is separate from the light conductor.

11. The motor vehicle headlamp as set for in claim 2 wherein the predetermined central point of the second light distribution area is located at an intersection point of the optical axis and the Petzval surface of the projection lens.

12. A motor vehicle headlamp comprising:

a first light source, a first primary lens system, a second light source, a second primary lens system, an aperture having an aperture edge, a projection lens having an optical axis, and a mirror being reflective, and wherein each of the first and second light sources is oriented to face the projection lens;

the first primary lens system being configured to transfer light of the first light source in a first beam-path being restricted by the aperture edge such that the first-beam path is restricted to be above the optical axis;

the second primary lens system being configured to focus light of the second light source in a second beam-path into a beam waist; and;

wherein the mirror is arranged in the second beam path and is disposed between the beam waist and the projection lens and is configured to reflect the light in the second beam path such that the second beam path is restricted to be below the optical axis.

13. The motor vehicle headlamp as set for in claim 12 wherein the first light source is disposed below the optical axis.

14. The motor vehicle headlamp as set for in claim 12 wherein the second light source is disposed below the optical axis.

15. The motor vehicle headlamp as set for in claim 12 wherein the first primary lens system is disposed partially above the optical axis and partially below the optical axis.

16. The motor vehicle headlamp as set for in claim 12 wherein the second primary lens system is disposed below the optical axis.

17. The motor vehicle headlamp as set for in claim 12 wherein the first light source is mounted on a first carrier and wherein the first primary lens system is coupled to the first carrier.

18. The motor vehicle headlamp as set for in claim 12 wherein the second light source is mounted on a second carrier and wherein the second primary lens system is coupled to the second carrier.
