Embodiment Construction

[0046] figure 1 is a perspective view of an optical element 1 comprising a main body 2 and two arms 3 on opposite sides of the main body 2 . Advantageously, the optical element 1 forms an integral assembly, which means that the body 2 and the arm 3 form a single assembly which cannot be disassembled in the event that one of the arm 3 or the body 2 is damaged. As described below, the optical element 1 is intended to be incorporated into an optical module, which itself is intended to be incorporated into a vehicle, such as a motor vehicle.

[0047] The main body 2 of the optical element 1 consists of a first end 4, a second end 5, two lateral surfaces 6, an upper surface 7 and a lower surface (in the figure 1 not visible in) limited. It should be noted that the terms "upper", "lower" and "lateral" refer to figure 1 The orientations of the optical element 1 in and examples of application in a given optical module, but these designations do not imply a limitation on the orienta...

Abstract

The invention relates to a monolithic optical element (1) comprising a first end (4) comprising a plurality of light inlets (10) different from each other through which light enters the optical element (1) , the optical element (1) comprises a second end (5) via which the light rays exit together, the second end (5) being configured to shape the light beam outside the optical element (1), the optical element ( 1) Defined by an axis (O) passing through at least the first end (4) and the second end (5), characterized in that the optical element (1) comprises at least a A first contact area (11) and at least a second contact area (12) dedicated to mechanically referencing it in a direction (D1) transverse to the axis (O), the second contact area (12) being closer to the second contact area (12) end (5) instead of the first end (4).

Description

technical field [0001] The present invention relates to the field of optical modules for lighting and / or signaling in motor vehicles, and more particularly to optical modules comprising optical means for forming various light beams, in particular for forming so-called "near" light" lights and lights known as "high beams". Background technique [0002] Motor vehicle headlamps generally consist of a housing enclosed by a transparent wall through which one or more beams of light pass. The housing houses at least one optical device, mainly comprising a light source and an optical element configured to shape the light produced by the light source in order to provide specific vehicle lighting and / or signaling services. For example, the optical element may be configured to allow a beam of light, known as a low beam, to be projected from the headlamp, in particular to limit dazzling the driver of an oncoming vehicle. [0003] In order to perform this low-beam headlamp function, th...
