Embodiment Construction

[0056] figure 1 A lighting system 1 is shown comprising an optical device 2 on which a module 3 supporting light emitting diodes is mounted directly. The module 3 is mounted on the optical device 2 by means of two guide rails 21 which form an integral part of the optical device 2 and into which an extension 31 forming part of the module 3 is inserted.

[0057] The module 3 supporting the diodes can also be used as a heat sink and heat dissipator for removing the heat generated by the diodes. The modules are preferably manufactured from sheet metal which is cut, pressed and bent into the desired shape.

[0058] The optical device 2 is usually made by injecting a thermosetting material or a plastic material, preferably a thermoplastic material, which is treated to provide a surface for use as a mirror 28 . The guide rail 21 is made in one piece with the optical device 2 and is thus positioned in a precise manner in the coordinate system of the optical device 2 . The orthonorm...

Abstract

Lighting device (1), notably a lighting and / or signalling device for a vehicle, comprising a light source (4) positioned on a module (3) assembled on an optical device (2), the optical device (2) and the module (3) comprising first referencing means comprising: - at least one guideway (21) mounted on the optical device (2), said guideway (21) comprising an interior reference face (22) positioned facing an interior guide face (24), and - at least one extension (31) extending from the module, said extension comprising a reference bearing face (32), opposite to a contact face (33), said contact face (33) having at least one point of contact (P), the contact face (33) being arranged so that once the extension (31) has been introduced into the guideway (21) in a direction of introduction (OX), the contact face (33) bears at the point of contact (P) against the interior guide face (24) and that, locally, at the point of contact, the guideway (21) and / or the extension (31) undergo elastic deformation.

Description

technical field [0001] The invention relates to the field of lighting systems and in particular to lighting systems eg for fitting to motor vehicles. Background technique [0002] A lighting system typically comprises a light source interacting with optical means, which may eg comprise a set of lenses and / or mirrors, reflectors, used to distribute light obtained from the light source in the lighting system. [0003] In these cases it is useful to position the light source relative to the optical reference of the optical system in a precise manner so that the light beam is properly directed towards the outside of the illumination system. [0004] This requirement for geometrical precision has increased with the use of light sources formed from light emitting diodes, and more particularly with the use of high power laser diodes, which enable the concentration of light emission to precise spots of very small size . These diodes are mounted on a module which acts as a heat sin...
