Abstract

A headlamp for a motor vehicle includes a first light source having light emitting diodes or laser diodes arranged in a matrix for generating a high beam distribution, at least one second light source for generating at least part of a low beam distribution, a first primary optics for the light emitted by the first light source, a second primary optics for the light emitted by the second light source, and a secondary optics including a refractive optical component. The light emanating from the first light source passes successively through the first primary optics and the refractive optical component of the secondary optics. The light emanating from the at least one second light source passes successively through the second primary optics and the refractive optical component of the secondary optics.

Claims (25)

1 . A headlamp for a motor vehicle, the headlamp comprising:

a first light source including light emitting diodes or laser diodes arranged in a matrix for generating a high beam distribution;

at least one second light source for generating at least a portion of a low beam distribution;

first primary optics for light emitted by the first light source;

second primary optics for light emitted by the at least one second light source; and

secondary optics including a refractive optical component having a first section and at least one second section,

wherein the headlamp is arranged such that the light emanating from the first light source passes successively through the first primary optics and the first section of the refractive optical component of the secondary optics,

wherein the light emanating from the at least one second light source passes successively through the second primary optics and the at least one second section of the refractive optical component of the secondary optics, and

wherein each second section of the at least one second section of the refractive optical component comprises a cylindrical lens array positioned on a side of the refractive optical component facing the second primary optics.

2 . The headlamp according to claim 1 , wherein the first light source, the at least one second light source, the first primary optics, the second primary optics and the secondary optics are combined to form a module.

3 . The headlamp according to claim 2 , wherein the first light source, the at least one second light source, the first primary optics, the second primary optics and the secondary optics are arranged on or in a common housing.

4 . The headlamp according to claim 1 , wherein the at least one second section of the refractive optical component is different from the first section of the refractive optical component.

5 . The headlamp according to claim 4 , wherein the at least one second section of the refractive optical component is spaced apart from the first section of the refractive optical component.

6 . The headlamp according to claim 1 , wherein cylindrical axes of cylindrical lenses of the cylindrical lens array are aligned vertically when the headlamp is installed in the motor vehicle.

7 . The headlamp according to claim 1 , wherein the first light source is a solid-state LED array.

8 . The headlamp according to claim 1 , wherein the headlamp comprises a control unit which is arranged to control the first light source such that an adaptive driving beam is generated.

9 . The headlamp according to claim 1 , wherein the first primary optics include at least one lens, wherein the at least one lens of the first primary optics contributes to imaging the first light source into an exterior of the motor vehicle.

10 . The headlamp according to claim 1 , wherein the at least one second light source comprises a plurality of second light sources.

11 . The headlamp according to claim 1 , wherein the second primary optics include at least one lens, wherein the at least one lens of the second primary optics contributes to imaging the at least one second light source into an exterior of the motor vehicle.

12 . The headlamp according to claim 11 , wherein the at least one second light source comprises a plurality of second light sources and the second primary optics include a plurality of lenses, and wherein each second light source of the plurality of second light sources is associated with a lens of the plurality of lenses of the second primary optics such that light emanating from the plurality of second light sources passes through the plurality of lenses of the second primary optics.

13 . The headlamp according to claim 1 , wherein the first light source is arranged on a printed circuit board and wherein the at least one second light source comprises a light emitting diode.

14 . The headlamp according to claim 13 , wherein the light emitting diode of the at least one second light source is arranged on the same printed circuit board as the first light source.

15 . The headlamp according to claim 1 , wherein the headlamp includes a heat sink associated with both the first light source and the at least one second light source.

16 . The headlamp according to claim 1 , wherein the portion of the low beam distribution generated by the at least one second light source, the second primary optics and the secondary optics is a prefield portion and/or a cut-off of the low beam distribution.

17 . The headlamp according to claim 1 , wherein the first section is designed as a projection lens.
