Embodiment Construction

[0091] figure 1 A support 20 for a light source 11 according to the invention is shown in place in a lighting device according to the invention. Only the shaping optical element 30 of the lighting device is shown in the figure.

[0092] In this embodiment, the shaping optical element is a reflector 30 having a front facing reflective surface 30a and a rear facing non-use surface 30b.

[0093] It can be seen that the support 20 is arranged relative to this reflector 30 such that the light source, here the LED 11 , directs the rays r1, r2 towards the reflective surface 30a. The reflective surface 30a is adapted to direct these rays r1, r2 in a specific direction to form a beam of given luminosity, in this embodiment an illumination beam.

[0094] In this embodiment, the support 20 is formed by a plate comprising a first part 21 and a second part 22 . Thus, both the first part 21 and the second part 22 are in the form of plates.

[0095] In this embodiment, when the supportin...

Abstract

The invention relates to a support (20) for a light source (11) of a lighting device for a motor vehicle, comprising: - an area for positioning the light source, - relative to three given axes (Z, X, Y) transverse to each other The reference elements (39, 36, 50) of the A first portion (51 ) extending from a first given axis (Z) of the given axis, and a second portion (52) extending transversely with respect to the first given axis (Z).

Description

technical field [0001] The present invention relates to the field of light source supports intended to be installed in vehicle lighting devices, and in particular to supports cooperating with shaping optical elements receiving light from the light sources that the support is intended to support. Background technique [0002] Known vehicle lighting devices comprise shaping optics adapted to deflect light rays from specific areas in the lighting device in order to give the light beam a given photometrics, in particular a legal photometrics. [0003] Furthermore, when installing a light source in a light emitting device, it is important that the light source can be installed precisely in a specific area and according to a precise orientation in three-dimensional space. [0004] To this end, the light source support comprises reference elements relative to three given axes transverse to each other, in particular three axes orthogonal to each other. These reference elements are ...
