Abstract

The present invention relates to a support for a light source of a lighting device of a motor vehicle, including a zone for positioning the light source, referencing elements with respect to three given mutually transverse axes, one of the referencing elements, termed a referencing element with two portions, a first portion extending along or parallel to a first axis of the three given axes, and a second portion extending transversely relative to this first given axis.

First claim

The invention claimed is:

1. A support for a light source of a lighting device of a motor vehicle, comprising:
a support comprising a sheet of metal having an oblong hole therein, the sheet of metal having a bend to provide a first surface and a second surface that is oriented on a side of the first surface and is transverse to the first surface;
a zone for positioning the a light source of the lighting device, the zone having a raised mounting surface that is raised with respect to the first surface and configured to mount the light source directly on the zone, and
referencing elements with respect to three given mutually transverse axes, wherein a first one of the referencing elements that is a referencing element with two portions, comprising: a first portion of the oblong hole extending along or parallel to a first given axis of the three given axes such that the first portion is on the first surface, and a second portion of the oblong hole extending transversely relative to the first given axis such that the second portion is on the second surface, wherein a connection portion the oblong hole is positioned on the bend and extends contiguously between the first portion and the second portion,; and

at least one of a plurality of complementary referencing elements coupled to the first portion, and the first portion is wider than the connection portion and the second portion of the first one of the referencing elements to limit movement of the at least one of a plurality of complementary referencing elements to the first portion one of the referencing elements.

2. The support according to claim 1 , further comprising:
a first surface extending transversely relative to the first given axis and comprising said second portion and said positioning zone, and a second surface that is oriented on a side of the first surface, is transverse to the first surface, extends along or parallel to the first given axis and comprises said first portion.

3. The support light emitting device according to claim 2 1, comprising a wall comprising the second surface, the first portion being a recess formed in the wall and opening onto the second surface.

4. The support light emitting device according to claim 2 1, wherein the first surface further comprises the other referencing elements.

5. The support according to claim 2 , wherein the first surface and the second surface join via a bent or curved surface portion, said referencing element with two portions being a hole straddling the first and second surfaces, a part of the hole on the first surface forming said second portion of said referencing element with two portions and a part of the hole on the second surface forming said first portion of said referencing element with two portions.

6. The support light emitting device according to claim 2 1, further wherein the sheet of metal comprising:
a first part in the form of a plate and comprising the first surface, and
a second part in the form of a plate comprising the second surface, the two plates being transverse to each other.

7. The support light emitting device according to claim 6 , wherein the first part further comprises at least three bosses forming a second referencing element comprising a plurality of projections on the first surface, a summit top of each of the at least three bosses plurality of projections being coplanar in a plane substantially perpendicular to said first given axis.

8. The support light emitting device according to claim 6 , wherein the support is produced by deformation of a the sheet of metalcomprising a rectilinear oblong hole extending along its length, the deformation being effected around a given direction perpendicular to this length in an area of said oblong hole.

9. The support light emitting device according to claim 1 , wherein the three given axes are orthogonal to one another.

10. The support light emitting device according to claim 1 , wherein the light source is fixed to the positioning zone, the light source being a light-emitting light source.

11. A vehicle The light-emitting device comprising: at least one support according to claim 1 , further comprising at least one shaping opticand, wherein said plurality of complementary referencing elements are adapted to be in contact with the referencing elements of the support, so that the shaping optic receives most of the light rays emitted by the light source and diverts them to form a given photometric beam.

12. The light-emitting device according to claim 11 , wherein said plurality of complementary referencing elements comprise a projection extending lengthwise along or parallel to a second of the three given axes, termed said second given axis, said referencing element with two portions of the support being a hole in the support, the projection extending into this hole and having zones of contact with edges of the hole, the zones of contact being on either side of the projection and aligned in a direction parallel to a third of the three given axis, termed the third given axis.

13. The light-emitting device according to claim 12 , wherein said plurality of complementary referencing elements comprise aligned slideways along or parallel to said second given axis, and the support further comprises tongues accommodated in the slideways and adapted to slide in the slideways.

14. The light-emitting device according to claim 13 , wherein the slideways comprise an end lying in a plane substantially perpendicular to said second given axis, and wherein the support includes the tongues each having an edge extending substantially perpendicularly to said second given axis and in contact with one of the ends.

15. The light-emitting device according to claim 14 , in which the support comprises at least three bosses distributed over the tongues and the slideways comprise sliding walls extending between an entry and the end of each of the slideways, the sliding walls being substantially perpendicular to said first given axis and oriented toward an interior of the slideway, each boss having a summit, each of the summits being coplanar in a plane substantially perpendicular to said first given axis, each of the summits of each of the bosses being in contact with the sliding walls.

16. The support according to claim 3 , wherein the first surface comprises the other referencing elements.

17. The support according to claim 3 , wherein the first surface and the second surface join via a bent or curved surface portion, said referencing element with two portions being a hole straddling the first and second surfaces, a part of the hole on the first surface forming said second portion of said referencing element with two portions and a part of the hole on the second surface forming said first portion of said referencing element with two portions.

18. The support according to claim 3 , further comprising:
a first part in the form of a plate and comprising the first surface, and a second part in the form of a plate comprising the second surface, the two plates being transverse to each other.

19. The support according to claim 7 , wherein the support is produced by deformation of a sheet of metal comprising a rectilinear oblong hole extending along its length, the deformation being effected around a given direction perpendicular to this length of said oblong hole.

20. The support according to claim 2 , wherein the three given axes are orthogonal to one another.

21. The light-emitting device according to claim 1, further comprising a second one of
