Abstract: A heat dissipation component for a vehicle lighting and/or signalling device of the type comprising a printed circuit board, a light-emitting diode comprising a heat dissipation base and a pair of electrical connection tabs and a heat dissipater extending facing the printed circuit board, wherein the heat dissipater comprises a heat exchange portion held against the base the diode and in that the heat exchange portion of the heat dissipater comprises means for orienting the diode that protrude substantially perpendicularly to the heat exchange portion of the dissipater, the heat exchange face of the base of the diode being arranged on an orienting means in such a way that the diode is oriented relative to a reference orientation and a reference plane of the dissipater.

Abstract: The welding method is for connecting together first and second metal elements (20, 16). The first element (20) forms a support or is for being fitted onto a support (12). During the method, a welding portion (20A) is formed in the first element (20), the welding portion having a connection end (22) connected to a support portion (20B) of the first element (20). A free end face (F) is formed in the welding portion (20A) of the first element (20) remote from the connection end (22). A high-energy beam (24) is directed onto the welding portion (20A) of the first element (20) in such a manner that the axis (X) of the beam (24) passes through the welding portion (20A) from the free end face (F) towards the connection end (22), thereby causing at least a portion of the mass of said first element (20) to melt, the molten mass coming into contact with the second element (16) by said mass collapsing.

Abstract: A lighting or signalling device in which a particular output unit of the device in question is formed, the output unit consisting of a stack of screens, independent of one another; each screen comprises a plurality of optical patterns produced in its thickness, able to divert light signals emitted by a light source; the spread of the light beam emerging from the device in question is thus adjustable in a first diffusion direction (OX), corresponding, for each screen in question, to a direction parallel to a plane defined by the screen and containing the optical patterns, and in a second diffusion direction (OZ), corresponding to a direction parallel to a plane roughly perpendicular to the planes defined by the screens, the spread on the second diffusion plane depending on the relative positions of the various screens. In this way in particular a “block of illuminated material” effect is obtained.
