L'invention concerne un procédé pour la fabrication de phares ouThe invention relates to a method for manufacturing headlights or

Le réflecteur de lampe ou phare de véhicule automobile constitué en matière synthétique est généralement fabriqué et formé en une seule pièce avec le carter enveloppe. La coloration éventuelle de l'éclairage, c'està-dire la couleur de la lumière émise, est dans la majorité des cas déterminée par le fabricant The lamp or headlight reflector of a motor vehicle made of synthetic material is generally manufactured and formed in one piece with the casing shell. The coloring of the lighting, that is to say the color of the light emitted, is in the majority of cases determined by the manufacturer

Les réflecteurs sombres de ce genre ainsi obtenus nécessitent l'apport ultérieur d'une couche réfléchissante claire, de préférence blanche ou gris argent. Cette couche est rapportée par des opérations de recouvrement de surface ultérieures, telles que vaporisation ou vernissage sur la surface intérieure du réflecteur. Cela signifie que, après réalisation par moulage à injection du phare sur des machines à injection de matière synthétique, la pièce obtenue doit être entreposée, nettoyée dans des installations de lavage, et finalement soumise à un traitement de surface. Cette fabrication en plusieurs étapes implique des dépenses de travail relativement importantes, qui The dark reflectors of this kind thus obtained require the subsequent addition of a clear reflecting layer, preferably white or silver gray. This layer is reported by subsequent surface coating operations, such as vaporization or varnishing on the inner surface of the reflector. This means that, after injection molding the headlight on plastic injection machines, the resulting part must be stored, cleaned in washing facilities, and finally subjected to a surface treatment. This multi-stage manufacturing involves relatively large work

L'invention a pour objet un procédé de fabrication d'un dispositif d'éclairage ou phare pour véhicule automobile, procédé caractérisé en ce qu'on réalise tout d'abord, dans une machine à coulée par injection, un carter enveloppe, notamment en matière synthétique thermoplastique, de la couleur désirée, on coule ensuite dans ce carter un réflecteur, notamment en matière synthétique thermoplastique, ces deux opérations pouvant être effectuées sur une seule machine à injection à deux couches en succession inverse, la coloration de la matière synthétique The invention relates to a method for manufacturing a lighting device or headlight for a motor vehicle, characterized in that firstly, in an injection molding machine, an envelope casing is produced, in particular thermoplastic synthetic material, of the desired color, it then flows into this housing a reflector, in particular thermoplastic synthetic material, these two operations can be performed on a single two-layer injection machine in reverse succession, the coloring of the synthetic material

La couche de revêtement de surface est détruite à cet endroit par le soudage et la nervure de liaison soudée apparalt alors dans la coloration du carter. En vue d'éviter cet inconvénient, l'invention prévoit que, la nervure de soudage et le bord du réflecteur se recouvrent exactement et sont reliés entre eux welding ration, a darkening of the edge of the glass. The surface coating layer is destroyed at this point by welding and the welded connecting rib then appears in the coloring of the housing. In order to avoid this drawback, the invention provides that the welding rib and the edge of the reflector overlap exactly and are interconnected.

Ce phare est monté dans la carrosserie d'un véhicule à laquelle il est fixé de manière démontable par des éléments a tick forming, on the one hand, an envelope housing 10 and, on the other hand, a reflector 11, with an incandescent lamp 12 shown without its mount, and a light passing speed 13. This headlight is mounted in the bodywork of a vehicle to which it is removably attached by

Le carter 10 présente essentiellement la forme du réflecteur et se prolonge, par l'intermédiaire d'un épaulement 16, en un cadre à bord rabattu vers l'extérieur 15. Le bord du réflecteur présente lui-même un bourrelet extérieur 17 qui The casing 10 has essentially the shape of the reflector and is extended, via a shoulder 16, into an outboard frame folded outwardly 15. The edge of the reflector itself has an outer bead 17 which

Le carter 10 et le réflecteur 11 sont constitués de préférence en une matière plastique thermoplastique. La matière prévue pour le carter 10 est de teinte sombre. La matière constituant le réflecteur 11 est pourvue d'une coloration telle qu'un traitement coloré spécial de la surface réfléchissante n'est pas nécessaire, par exemple une teinte blanche ou gris argenté, La vitre de passage de la lumière 13 est pourvue d'une nervure circulaire 18, qui se recouvre exactement avec le bord, c'est-àdire le bourrelet extérieur 17 du réflecteur, avec lequel elle est reliée de manière non démontable, notamment par soudage The housing 10 and the reflector 11 are preferably made of a thermoplastic plastic material. The material provided for the housing 10 is dark. The material constituting the reflector 11 is provided with a coloring such that a special color treatment of the reflective surface is not necessary, for example a white or silver-gray tint, The light-passing window 13 is provided with a circular rib 18, which overlaps exactly with the edge, that is to say the outer bead 17 of the reflector, with which it is connected in a non-removable manner, in particular by welding
