Abstract

The invention relates to a light module ( 1 ) for a motor vehicle or for a motor vehicle headlamp, wherein the light module ( 1 ) has at least two or more light sources ( 10, 11 ), which are positioned in defined positions relative to one another, and wherein the light module ( 1 ) also has two or more reflectors ( 20, 21 ), wherein at least one reflector ( 20, 21 ) is associated with each light source ( 10, 11 ), wherein at least one of the reflectors ( 20, 21 ) is movably connected to at least one adjacent reflector ( 20, 21 ).

First claim

The invention claimed is:

1. A light module for a motor vehicle headlamp, the light module comprising:
two or more LED light sources, which are each positioned in defined positions relative to one another; and
two or more reflectors, which are each associated with a single LED light source of the two or more LED light sources,
wherein the two or more reflectors are movably connected by at least one film hinge;
wherein the two or more LED light sources are mounted on a circuit board, and
wherein each of the two or more reflectors is positionable and referenceable independently of the other reflector(s) on the circuit board with respect to the LED light source associated therewith to an extent provided by a flexibility of the at least one film hinge.

2. The light module according to claim 1 , wherein at least one of the two or more reflectors is movably connected to all adjacent reflectors.

3. The light module according to claim 1 , wherein each of the two or more reflectors is movably connected to one or more reflectors adjacent thereto.

4. The light module according to claim 1 , wherein the two or more reflectors are arranged laterally adjacent to one another.

5. The light module according to claim 1 , wherein the two or more reflectors are arranged movably relative to one another in a plane.

6. The light module according to claim 5 , wherein the two or more reflectors are movably mounted in a common plane.

7. The light module according to claim 1 , wherein the at least one film hinge comprises two or more film hinges.

8. The light module according to claim 7 , wherein the two or more film hinges have different normal distances from a plane in which the two or more reflectors are movable relative to one another.

9. The light module according to claim 7 , wherein the two or more reflectors are interconnected by exactly two film hinges.

10. The light module according to claim 1 , wherein the at least one film hinge is a plastic hinge.

11. The light module according to claim 1 , wherein the two or more reflectors are formed as plastic reflectors.

12. The light module according to claim 1 , wherein each LED light source comprises one or more light-emitting diodes.

13. The light module according to claim 1 , wherein the two or more reflectors have, on their sides facing the circuit board for the LED light sources in a fastened state, fastening elements with which the two or more reflectors are fastened to corresponding fastening elements of the circuit board, and wherein the two or more reflectors have, on their sides facing the circuit board for the LED light sources in a fastened state, referencing elements with which the two or more reflectors are positioned on corresponding referencing elements of the circuit board.

14. The light module according to claim 13 , wherein the fastening elements and/or the referencing elements of the two or more reflectors are formed as protruding pins.

15. The light module according to claim 14 , wherein the fastening elements and/or referencing elements on the circuit board are formed as bores corresponding to the protruding pins.

16. A vehicle headlamp comprising one or more light modules according to claim 1 .

17. The light module according to claim 1 , wherein the two or more reflectors are interconnected by a plurality of film hinges that are formed in one piece with the two or more reflectors.
