Embodiment Construction
[0026] With reference to the preceding figures, reference numeral 4 designates a lighting and / or signaling device, such as a car lamp, to which reference will be made hereinafter, without loss of generality.
[0027] As mentioned above, the expression "lighting and / or signaling device" refers to a vehicle rear lamp or a vehicle headlamp, the latter also referred to as a headlamp or headlamp, including at least one external vehicle with an illuminated and / or Lights for signaling functions, such as, for example, position lights (which may be front position lights), tail lights, side marker lights, turn signals, brake lights, rear fog lights, high beam headlights, low beam headlights, and the like.
[0028] Furthermore, the term lighting and / or signaling means also means interior dome lights, instrument panels or parts thereof, displays and the like.
[0029] Thus, as described in more detail below, in its signaling function, the device may include the possibility to transmit opt...

A lighting and signaling device (4), in particular for use in the automotive field, comprising:-a container body (8) delimiting a containment housing (12) closed by a lenticular body (20), the container body (8) containing at least one first light source (24) and being closed by the lenticular body (20), a first light guide (28) configured to at least partially receive as input a light beam generated by said at least one first light source (24), a light beam is transmitted by total internal reflection along a first main propagation direction (X1-X1) and sent as output from the lenticular body (20),-at least one fixing and / or shielding element (32), which is opaque to said light beam, associated with a first light guide (28) at a first interface wall (36), the fixing and / or shielding element (32) has a first interface wall (36) and is directly or indirectly fixed to the container body (8) for mechanically locking the first light guide (28) to the container body (8), wherein the first light guide (28) is mechanically fixed to the fixing and / or shielding element (32) by at least one first weld (40) protruding from the first interface wall (36).
Description
technical field [0001] The present invention relates to a vehicle lighting and / or signaling device and a method for assembling the same. Background technique [0002] The term automotive lighting and / or signaling device is used here in a very broad sense to include automotive lights, whether rear or front, the latter also referred to as headlights or headlamps. [0003] As is known, a car light is a device intended to provide lighting and / or signaling functions for a vehicle, such as position lights, turn signals, brake lights, rear fog lights, reversing lights, low beam headlights, high beam headlights, and the like. [0004] Furthermore, the term should also be understood to include dome lights, instrument panels or parts thereof; thus, automotive lighting and / or signaling devices may be placed inside or outside the vehicle. [0005] As is known, such automotive lighting and / or signaling devices essentially comprise a hollow container body which accommodates at least one ...
