Abstract

L'invention concerne un procédé de fabrication d'une lampe du type comprenant un corps creux muni d'une couche réfléchissante. Il est caractérisé par le fait qu'il consiste à placer l'extrémité utile d'une torche à plasma près de la couche réfléchissante du corps et à balayer par un gaz neutre une partie de ladite couche sur le pourtour, à provoquer un déplacement du corps par rapport à la torche, de façon que ladite zone de la couche réfléchissante soit retirée du corps et à fixer, à l'aide d'un produit adhésif, une lentille sur la zone de la surface interne de laquelle on a retiré la couche réfléchissante. L'invention s'applique à la fabrication des phares d'automobile.The invention relates to a method of manufacturing a lamp of the type comprising a hollow body provided with a reflective layer. It is characterized by the fact that it consists in placing the useful end of a plasma torch near the reflecting layer of the body and in sweeping part of said layer around the periphery with a neutral gas, to cause a displacement of the body relative to the torch, so that said area of the reflective layer is removed from the body and to fix, with an adhesive, a lens on the area of the inner surface from which the layer has been removed reflective. The invention applies to the manufacture of automobile headlights.
