Problems solved by technology

[0006] Various disadvantages arise from this construction and the resulting method of assembly
Regarding the assembly method itself, the requirement to screw each optic individually onto the attachment support requires considerable assembly time
Furthermore, with regard to the design of the optical elements required to assemble such a module, it is necessary to provide machining operations to form each opening of the optical element and to provide specific positions that are not detrimental to the optical function, needing to be the areas in which the openings have to be formed Providing a specific thickness such that designing these optics presents equally the optical challenge of providing proper light guidance and the mechanical challenge of ensuring proper attachment on the support
Another disadvantage of this solution is that the optics are mechanically stressed by the screws

Embodiment Construction

[0052] figure 1 A light module 1 according to the invention is shown, also called an optical module, the purpose of which is to generate one or more light beams and project them on the road. Such a lamp module 1 is intended to be installed in a headlamp of a motor vehicle, which is not shown in the figures for a better understanding of the invention. It should be noted that the headlamps discussed herein generally comprise a rear housing closed at the front by a transparent outer lens through which the light generated by the lamp module according to the invention passes. Thus, such a headlight can receive a plurality of light modules and at least one light module according to the invention in its inner volume delimited by the rear housing and the transparent outer lens.

[0053] Such a light module 1 forms a single subassembly, ie the object can fulfill its purpose without any contribution other than the electrical energy required for its illumination.

[0054] The lamp modu...

Abstract

A lamp module (1) for a motor vehicle headlamp, comprising at least two light sources, two optical elements (2, 3, 4) respectively configured for guiding light rays emitted by the light sources, and an attachment support (5), the optical element and the light source are placed against the attachment support (5). The optical elements comprise at least one first optical element (2) associated with the first light source and one second optical element (3) associated with the second light source. The lamp module (1) comprises a frame (6) for holding the optical elements (2, 3, 4) on the attachment 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 lamp modules intended to be installed in vehicle headlamps. Background technique [0002] Motor vehicle headlamps are usually formed by a housing which is closed by a transparent wall through which the light passes. The housing accommodates at least one lamp module, essentially comprising at least one light source and an optical system capable of modifying at least one parameter of the light generated by the light source in order to emit light rays capable of passing through the transparent walls of the headlamp, thereby forming prescribed beam. [0003] Due to the low energy consumption of light-emitting diodes (LEDs), the low space requirements and the quality of lighting obtained, technological progress tends to favor the use of light sources formed by at least one LED. [0004] The optical system equipped with t...
