Abstract
Method of manufacture of an automotive light comprising the steps of providing a container body delimited by a first perimetral profile, providing a lenticular body, internally delimited by a second perimetral profile and externally by an outer edge corresponding to said second perimetral profile, wherein the container body acts as an absorbent element of the light beam and the lenticular body acts as a transmission element of the light beam, providing optical devices for changing the divergence of the portions of laser beams in output from the fibers, so as to collimate them overall along at least one predetermined optical axis. The method further comprises the steps of directing on a critical portion of the welding interface at least a first laser beam emitted by a respective fiber lying on an optical plane incident with said critical portion of the welding interface.
