Lighting module for a motor vehicle

1. A motor vehicle headlight with at least one light module, wherein the at least one light module comprises:

a heat sink;

a carrier plate for at least one light source secured on the heat sink; and

at least one light source arranged on the carrier plate;

wherein the carrier plate has at least one reference position for referencing a reflector or other light-shaping member to the carrier plate in a specific position,

wherein the reflector or other light-shaping member has a securing base, by means of which securing base the reflector or other light-shaping member can be referenced to the at least one reference position of the carrier plate,

wherein the securing base is assigned at least one return element, by means of which the securing base can be secured at least temporarily in the reference position thereof in relation to the carrier plate,

wherein the at least one return element in the reference position of the securing base is biased between the securing base and a stop region of the heat sink in such a way that the securing base is held in the reference position thereof in relation to the carrier plate.

2. The motor vehicle headlight of claim 1 , wherein the carrier plate is bonded to the heat sink.

3. The motor vehicle headlight of claim 1 , wherein the at least one light source is an LED light source which has one or more light-emitting diodes, and the carrier plate is a printed circuit board for the LED light source.

4. The motor vehicle headlight of claim 1 , wherein at least one fastening element is provided in order to secure the securing base on the heat sink.

5. The motor vehicle headlight of claim 4 , wherein the at least one securing element is a spring.

6. The motor vehicle headlight of claim 5 , wherein the spring is a sheet metal spring.

7. The motor vehicle headlight claim 6 , wherein the sheet metal spring is provided in the form of a yoke spring.

8. The motor vehicle headlight of claim 1 , wherein the return element comprises at least one spring element.

9. The motor vehicle headlight of claim 8 , wherein the at least one spring element is formed in one piece with the securing base.

10. The motor vehicle headlight of claim 1 , wherein the at least one light source has a lightest region and the at least one reference position is arranged on the carrier plate in relation to the geometric centre of the at least one light source or in relation to the lightest region of the at least one light source.

11. The motor vehicle headlight of claim 1 , wherein the at least one reference position is provided in the form of a slot or other hole or is provided in the form of a reference edge.

12. The motor vehicle headlight claim 11 , wherein the at least one reference position comprises two or more reference positions running in a straight line.

13. The motor vehicle headlight of claim 1 , wherein the at least one reference position is drilled and/or milled.

14. The motor vehicle headlight of claim 1 , wherein the heat sink has two portions and the carrier plate is arranged on one of the portions.

15. The motor vehicle headlight of claim 14 , wherein the stop region for the return element is fixed on one or both of the two portions.

16. The motor vehicle headlight claim 15 , wherein the stop region is formed in one piece with one or both of the two portions.

17. The motor vehicle headlight claim 14 , wherein the two portions are arranged at right angles to one another.

18. A light module for a motor vehicle or for a motor vehicle headlight, wherein the light module comprises:

a heat sink;

a carrier plate for at least one light source secured on the heat sink; and

at least one light source arranged on the carrier plate;

wherein the carrier plate has at least one reference position for referencing a reflector or other light-shaping member,

wherein the reflector or other light-shaping member has a securing base, by means of which securing base the reflector or other light-shaping member can be referenced to the at least one reference position of the carrier plate,

wherein the securing base is assigned at least one return element, by means of which the securing base can be secured at least temporarily in the reference position thereof in relation to the carrier plate,

wherein the return element comprises at least one spring element formed in one piece with the securing base,

wherein the at least one return element in the reference position of the securing base is biased between the securing base and a stop region of the heat sink in such a way that the securing base is held in the reference position thereof in relation to the carrier plate.

19. A light module for a motor vehicle or for a motor vehicle headlight, wherein the light module comprises:

a heat sink;

a carrier plate for at least one light source secured on the heat sink; and

at least one light source arranged on the carrier plate;

wherein the carrier plate has at least one reference position for referencing a reflector or other light-shaping member,

wherein the heat sink has two portions arranged at right angles to one another and the carrier plate is arranged on one of the portions,

wherein the reflector or other light-shaping member has a securing base, by means of which securing base the reflector or other light-shaping member can be referenced to the at least one reference position of the carrier plate,

wherein the securing base is assigned at least one return element, by means of which the securing base can be secured at least temporarily in the reference position thereof in relation to the carrier plate,

wherein the at least one return element in the reference position of the securing base is biased between the securing base and a stop region of the heat sink in such a way that the securing base is held in the reference position thereof in relation to the carrier plate.
