Problems solved by technology

The problem is that the attenuation obtained with this known solution is then applied equally to the horizontal and vertical cutoffs, for which a relatively high sharpness is absolutely required in the case of the ADB function in order to prevent dazzle

Embodiment Construction

[0038] refer to figure 2 , the lens 200 for the optical module includes an optical incident surface (not shown) and an optical exit surface 202 . The lens 200 is converging and has an optical axis shared with the optical entry surface and the optical exit surface 202 . In the embodiment employed, the lens 200 is biconvex, but it may include flat or concave surfaces and remain within the scope of the invention.

[0039] The lens 200 comprises a first series of patterns (not shown) extending in a first direction on its optical entrance surface and a second series 204 of patterns 206 extending in a second direction on its optical exit surface 202. The first and second directions are substantially perpendicular.

[0040] In the example shown, each optical surface includes a single series of patterns. According to a variant, said one and / or other optical surface each comprise a plurality of independent series of patterns, for example three, each extending in the same direction ...

Abstract

An optical module (400) for a lighting and / or signaling device, comprising at least one light source generating a light beam, at least one cutting means from the light beam or the medium (s) cutoff being arranged (s) for generating at least a low cut and a cut side of the light beam from the light source and a first and a second optically active surfaces disposed in succession along the path of the light beam after the cutting means. The optical module is characterized by that the first optically active surface comprises at least a first series of patterns which extend in a first direction and the second optically active surface comprises at least a second series of patterns which extend in a second direction; said first and second directions being substantially perpendicular. Lighting and / or signaling motor vehicle comprises at least one such module.

Description

technical field [0001] The invention relates to the field of lighting and / or signaling of motor vehicles, and more particularly to an optical module and a lighting and / or signaling device for a motor vehicle. Background technique [0002] It has been customary for motor vehicles to be equipped with at least one optical lighting and / or signaling device, usually a pair of optical devices, comprising multiple At least one lighting module that illuminates a road with a lighting beam. [0003] In order to perform the low-beam function, the optics of the first vehicle must produce a beam with a horizontal cut-off mainly below the horizon in order to prevent blinding the driver of the second vehicle when meeting or in front of the first vehicle . [0004] For this purpose, it is known practice to provide an optical device with a shutter and lenses arranged so as to produce this horizontal cut-off, the shutter being formed by a reflective horizontal surface, also called a beam ben...
