Abstract: A light-emitting device including a light source with at least one light-emitting diode, and a housing defining an enclosure for the light source, the light source being in thermal contact with the housing to dissipate heat released by the light source, the housing including a hollow rib.

Abstract: The invention relates to a lighting and/or signaling module comprising a support, a light guide arranged in an enclosure of said support and a mask arranged on the support and extending in front of the light guide. The light guide comprises a longitudinal rib intended to collaborate by engaging with a series of hooks belonging to the support. The mask is intended to mask the mounting zones of the light guide. It comprises one or more windows intended to let through the rays of light emitted transversally by the light guide. The rib extends continuously over essentially the entire length of each of the windows. The rib allows simple, rapid and reliable attachment of the light guide to its support. The continuity of the rib among each of the windows means that the creation of any visible non-uniformity through said windows is avoided.
