Lighting modules for vehicle lights

Abstract

A lighting module (1) for a motor vehicle lamp, comprising a plurality of light sources, a plurality of optical elements (2, 3, 4) and a fixed support (5), the optical elements being respectively configured to reflect light emitted by the light sources Guided, optical elements and light sources are arranged against said fixed support (5), the optical elements comprising a first optical element associated with a first light source (202), a second optical element associated with a second light source (3) and a third optical element (4) associated with the third light source. The first optical element (2) comprises means (6) for holding the second optical element (3) and the third optical element (4) on a fixed support (5).

Description

technical field [0001] The invention relates to the field of lighting and / or signaling devices for motor vehicles. More specifically, the invention relates to a lighting module intended to be installed in a vehicle lamp. Background technique [0002] Motor vehicle lights are usually made of a housing which is closed by a transparent wall through which the light passes. The housing accommodates at least one lighting module, essentially comprising at least one light source and an optical system adapted to modify at least one parameter of the light produced by the light source to emit light that can then pass through the transparent wall of the lamp to form Statutory beam. [0003] Technological developments tend to favor the use of light sources consisting of at least one light emitting diode (LED) because of their low energy consumption, small overall size and the quality of the lighting obtained. [0004] An optical system equipped with a lighting module may include an op...

AI Technical Summary

Problems solved by technology

[0006] Various disadvantages stem from this construction and the final assembly process

Regarding the assembly process itself, the necessity to individually fix each optic by screwing it onto a fixed support creates long assembly times

Furthermore, where the design of the optical elements is involved to equip such a module, it is necessary to provide a specific positioning, not to be detrimental to the optical function, as well as a specific thickness of the area in which the openings have to be made, so the design of these optical elements involves There are as many optical issues (to ensure the light is directed correctly) as there are mechanical issues (to ensure proper fixation to the support)

Another drawback of this solution stems from the fact that the optical elements are mechanically stressed by screwing them on a fixed support
