Abstract

Titre : Glace de fermeture d’un dispositif lumineux pour véhicule. La présente invention concerne une glace de fermeture (4) d’un dispositif lumineux (2) pour véhicule (1) comprenant au moins une première couche transparente (6) en un matériau polymère, caractérisée en ce que la glace de fermeture (4) comprend au moins une deuxième couche transparente (8) et une troisième couche transparente (10) formées par traitement d’au moins un composant précurseur (CP), les couches étant réalisées en recouvrement les unes des autres, le traitement d’au moins l’une des deuxième couche transparente (8) et/ou troisième couche transparente (10) étant assistée par plasma atmosphérique à torche plasma. Figure 2.Title: Closing glass of a vehicle light device. The present invention relates to a closing glass (4) of a lighting device (2) for a vehicle (1) comprising at least a first transparent layer (6) made of a polymer material, characterized in that the closing glass (4) comprises at least a second transparent layer (8) and a third transparent layer (10) formed by treatment of at least one precursor component (CP), the layers being produced overlapping each other, the treatment of at least one one of the second transparent layer (8) and/or third transparent layer (10) being assisted by atmospheric plasma with a plasma torch.
