Provided is a method for manufacturing an automotive light (4), comprising the steps of: providing a container body (8) delimited by a first peripheral profile (20); providing a lenticular body (24), internally delimited by a second peripheral profile (28) and externally delimited by an outer edge (32) corresponding to the second peripheral profile (28); associating at least partially with each other the respective first and second peripheral profiles (20,28) of the container body (8) and the lenticular body (24), the contact surface between the peripheral profiles (20,28) defining a welding interface (48) which extends along a curve defined by a curvilinear abscissa (s); providing at least one laser emitting device which emits a light beam or radiation having a characteristic emission spectrum; providing a plurality of fibres (44), while receiving portions of the laser beam from the laser emitter device and direct the portions of the laser beam toward the welding interface (36) through the lenticular body (24), wherein the container body (8) acts as an absorbent element of the light beam and the lenticular body (24) acts as a transmission element of the light beam; and providing optical devices (52) for changing the divergence of the portions of laser beams in output from the fibres (44), so as to collimate the portions of laser beams overall along at least one predetermined optical axis (X-X). |
