AI Technical Summary
Technical Problem
Existing automotive lighting and signaling devices face challenges in securely fixing light guides without causing optical defects, such as light leakage or improper reflection, which are time-consuming and costly in conventional methods like welding and adhesion.
Method used
The use of laser welding to connect light guides to screen elements within the device, forming opaque molten mixtures that secure the light guides without altering their optical properties, using male and housing structures to ensure a durable and efficient assembly.
Benefits of technology
This method provides a fast, reliable, and cost-effective assembly that maintains light transmission integrity, avoiding optical defects and reducing production time and costs compared to conventional methods.

Abstract
The present invention relates to lighting and / or signaling devices for automobiles and methods for assembling the same. [Solution] The housing 12 is enclosed by a lenticular body 20 and houses at least one first light source, the first light guide 28 is configured to receive the light beam generated by the at least one first light source as input at least partially and send it out as output from the lenticular body 20, at least one fixed and / or screen element is opaque to the light beam and is associated with the first light guide 28 at the first interface wall and is fixed directly or indirectly to the container body 8, the first light guide 28 is mechanically fixed to the fixed and / or screen element 32 by at least one first weld protruding from the first interface wall.
