Abstract
Description
L'invention concerne une lanterne de signalisation pour véhicule automobile comprenant un socle fixé a la carrosserie du véhicule et portant une pluralité d'ampoules électriques séparées par des cloisons solidaires dudit socle, chaque ampoule étant entourée d'une surface réfléchissante produisant un faisceau réfléchi parallèle, les divers faisceaux réfléchis étant parallèles entre eux, un couvercle transparent unique recouvrant lesdites ampoules, un organe de coloration de la lumière étant associé à au moins plusieurs desdites ampoules et un réseau opaque étant disposé à l'extérieur desdits organes de coloration. The invention relates to a signal lantern for a motor vehicle comprising a base fixed to the vehicle body and carrying a plurality of electric bulbs separated by partitions integral with said base, each bulb being surrounded by a reflecting surface producing a parallel reflected beam. , the various reflected beams being parallel to each other, a single transparent cover covering said bulbs, a light coloring member being associated with at least several of said bulbs and an opaque network being arranged outside said coloring members.
Les lanternes de signalisation du type précédent permettent d'obtenir, lorsqu'aucune ampoule n'est allumée, un aspect uniforme du feu alors que l'allumage d'une ampoule permet d'obtenir un éclairage coloré par l'organe de coloration correspondant à l'ampoule allumée. Cette caractéristique permet d'obtenir une esthétique améliorée pour la lanterne. En outre, la lanterne a une construction simplifiée du fait que le couvercle transparent est d'une seule pièce. Signaling lanterns of the above type make it possible to obtain, when no bulb is lit, a uniform appearance of the fire, while lighting a bulb makes it possible to obtain colored lighting by the coloring member corresponding to the lighted bulb. This characteristic makes it possible to obtain an improved aesthetic for the lantern. In addition, the lantern has a simplified construction because the transparent cover is in one piece.
Cependant, ces lanternes connues ne permettent pas d'obtenir des colorations apparentes nettes autres que des aspects brillants ou grisatres. However, these known lanterns do not make it possible to obtain clear apparent colorings other than shiny or grayish aspects.
La présente invention vise à permettre l'obtention d'un aspect, à l'état éteint, de toute coloration voulue, tout en conservant d'excellentes caractéristiques photométriques, avec une construction simple et économique. The present invention aims to allow obtaining an appearance, in the off state, of any desired coloring, while retaining excellent photometric characteristics, with a simple and economical construction.
A cet effet, la lanterne selon l'invention est caractérisée par le fait que ledit réseau opaque est constitué par des bandes parallèles opaques rapportées sur la face extérieure dudit couvercle transparent, lesdites bandes opaques étant séparées par des rainures parallèles ménagées dans la face extérieure dudit couvercle, des lignes parallèles adjacentes de lentilles toriques étant formées dans la face intérieure dudit couvercle, chaque ligne de lentilles étant alignée avec une desdites rainures paral lèlement à la direction commune de réflexion desdits réflecteurs. To this end, the lantern according to the invention is characterized in that said opaque network is constituted by opaque parallel strips attached to the outside face of said transparent cover, said opaque strips being separated by parallel grooves formed in the outside face of said cover, adjacent parallel lines of toric lenses being formed in the inner face of said cover, each line of lenses being aligned with one of said grooves parallel to the common direction of reflection of said reflectors.
De préférence, les bandes parallèles opaques sont constituées par un dépit sur la surface extérieure du couvercle transparent entre ledites rainures. Dans une forme d'exécution, ledit dépôt est constitué par un marquage à chaud. Preferably, the opaque parallel strips are formed by a coating on the outer surface of the transparent cover between said grooves. In one embodiment, said deposit consists of hot stamping.
Dans une variante de réalisation, la face extérieure du couvercle comportant lesdites bandes opaques est recouverte par un surmoulage transparent qui protège les bandes opaques et peut en outre permettre d'obtenir une surface externe entièrement lisse. In an alternative embodiment, the outer face of the cover comprising said opaque strips is covered by a transparent overmolding which protects the opaque strips and can also make it possible to obtain an entirely smooth external surface.
L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel
- la figure 1 est une vue schématique en coupe longitudinale d'une lanterne selon un exemple de réalisation de l'invention
- la figure 2 est une vue de face de la lanterne de la figure 1;
- la figure 3 est une vue en coupe longitudinale, à très grande échelle, d'une portion d'un couvercle transparent de lanterne selon une forme d'exécution de l'invention;
- la figure 4 est une vue en coupe selon la ligne IV-IV de la figure 3; et
- les figures 5 et 6 sont analogues respectivement aux figures 3 et 4, mais pour la forme de réalisation de la figure 1.The invention will be clearly understood on reading the following description made with reference to the appended drawing in which
- Figure 1 is a schematic view in longitudinal section of a lantern according to an exemplary embodiment of the invention
- Figure 2 is a front view of the lantern of Figure 1;
- Figure 3 is a longitudinal sectional view, on a very large scale, of a portion of a transparent lantern cover according to an embodiment of the invention;
- Figure 4 is a sectional view along line IV-IV of Figure 3; and
- Figures 5 and 6 are similar to Figures 3 and 4 respectively, but for the embodiment of Figure 1.
La lanterne comprend un socle 1, fixé à la carrosserie (non représentée) et portant des ampoules électriques 2, 3, 4. The lantern comprises a base 1, fixed to the body (not shown) and carrying electric bulbs 2, 3, 4.
Les portions 5 du socle 1 entourant chaque ampoule sont réfléchissantes et ont une forme telle que les faisceaux réfléchis 6 sont parallèles et parallèles entre eux. L'ampoule 2 est entourée par un cabochon transparent 7 coloré (par exemple en rouge pour la fonction "stop"), l'ampoule 3 par un cabochon 8 coloré (par exemple en ambre pour la fonction "indicateur de direction") alors que l'ampoule 4 ne comporte pas de cabochon (lumière blanche pour la fonction "recul"). Les cabochons 7 et 8 peuvent comporter des reliefs produisant un faisceau de sortie 9 parallèle et parallèle aux faisceaux 6. Les ampoules sont séparées les unes des autres par des cloisons 10 solidaires du socle 1.The portions 5 of the base 1 surrounding each bulb are reflective and have a shape such that the reflected beams 6 are parallel and parallel to each other. The bulb 2 is surrounded by a transparent cabochon 7 colored (for example in red for the "stop" function), the bulb 3 by a cabochon 8 colored (for example in amber for the function "direction indicator") while the bulb 4 does not have a lens (white light for the "recoil" function). The cabochons 7 and 8 may include reliefs producing an output beam 9 parallel and parallel to the beams 6. The bulbs are separated from each other by partitions 10 secured to the base 1.
La lanterne est fermée par un couvercle transparent 11 unique recouvrant l'ensemble des ampoules et fixé sur le socle 1.The lantern is closed by a single transparent cover 11 covering all the bulbs and fixed on the base 1.
L'invention concerne plus particulièrement le couvercle 11. The invention relates more particularly to the cover 11.
Dans la forme de réalisation des figures 3 et 4, la surface extérieure du couvercle 11 comporte des rainures transversales 12 ménageant entre elles des bandes parallèles en relief 13. La largeur des rainures 12 est environ égale au tiers de la largeur des bandes 13. Les bandes 13 sont recouvertes d'un revetement opaque 14, qui peut entre coloré dans une couleur choisie, par exemple celle de la carrosserie, et avoir tout aspect souhaité, tel que brillant ou mat. Le revêtement 14 peut etre constitué par exemple par un marquage à chaud avec un film de couleur. In the embodiment of Figures 3 and 4, the outer surface of the cover 11 has transverse grooves 12 forming between them parallel bands in relief 13. The width of the grooves 12 is approximately equal to one third of the width of the bands 13. The strips 13 are covered with an opaque coating 14, which can be colored in a chosen color, for example that of the bodywork, and have any desired appearance, such as gloss or matt. The coating 14 can be constituted for example by hot stamping with a colored film.
La surface intérieure du couvercle 11 comporte des lignes adjacentes 15 de reliefs toriques 16, chaque ligne 15 étant dans un plan passant par l'axe d'une rainure 12 et parallèle aux faisceaux réfléchis 6 et 9. La courbure des reliefs toriques 16 est telle que les faisceaux incidents 6-9 sont réfractés sensiblement au niveau de la rainure 12 adjacente et sortent du couvercle 11 selon des faisceaux divergents 17. Le rayon du tore des reliefs 16 est tel que les faisceaux incidents 6-9 sont réfractés selon des faisceaux convergents 18. Cette caractéristique assure une bonne diffusion de la lumière en direction longitudinale tout en limitant sa diffusion transversalement. On notera que la disposition adjacente des lignes 15 assure une transmission intégrale des rayons incidents 6-9 vers l'extérieur à travers les rainures 12, aucun rayonnement n'étant réfracté sur les bandes 13. The inner surface of the cover 11 has adjacent lines 15 of toric reliefs 16, each line 15 being in a plane passing through the axis of a groove 12 and parallel to the reflected beams 6 and 9. The curvature of the toric reliefs 16 is such that the incident beams 6-9 are refracted substantially at the level of the adjacent groove 12 and exit the cover 11 according to divergent beams 17. The radius of the torus of the reliefs 16 is such that the incident beams 6-9 are refracted according to convergent beams 18. This characteristic ensures good light diffusion in the longitudinal direction while limiting its transverse diffusion. It will be noted that the adjacent arrangement of the lines 15 ensures an integral transmission of the incident rays 6-9 to the outside through the grooves 12, no radiation being refracted on the strips 13.
Dans la variante des figures 5 et 6, une couche 19 de matière transparente a été surmoulée sur la surface extérieure du couvercle 11. Cette couche 19 assure la protection des bandes opaques 14 et permet d'obtenir une surface externe completement lisse. La couche 19 a pour effet optique d'augmenter la divergence des faisceaux émergents 17 en direction transversale. In the variant of FIGS. 5 and 6, a layer 19 of transparent material has been overmolded on the outer surface of the cover 11. This layer 19 provides protection for the opaque strips 14 and makes it possible to obtain a completely smooth outer surface. The layer 19 has the optical effect of increasing the divergence of the emerging beams 17 in the transverse direction.
