摘要： Simultaneous laser welding equipment of a vehicle light including at least a plurality of laser sources suitable for emitting light beams, a plurality of optical fibres associated, at the input ends to the at least one laser source and transmitting the light beams. A light guide is provided with at least one hollow seat that delimits a continuous perimetral contour, counter-shaped to the weld interface. The light guide comprises diffusion elements that pass through the perimetral contour of the seat of the light guide internally, so as to intercept and influence the light beams that propagate inside the seat and that are shaped to expand the light beams along a direction substantially tangent to the curvilinear abscissa defining the perimetral contour, before it projects from the light output wall and/or at the latter.

摘要： A simultaneous laser welding apparatus of a vehicle light comprising a placement support for a container body and a lenticular body of a vehicle light welded together at reciprocal perimeter profiles, a plurality of laser sources, a plurality of optical fibres associated with the laser sources at input ends for transmitting the light beams, a fibre-holder support device for blocking output ends of the optical fibres in predetermined positions, spaced apart by a pitch, a light guide provided with at least one seat which receives the light beams coming from the output ends of the optical fibres, to a light output wall which sends the light beams towards the welding interface. A single optical fibre is associated with each laser source.
