Description

L'invention vise des feux de signalisation de véhicules automobiles et plus particulièrement des feux de changements de direction.The invention relates to signaling lights for motor vehicles and more particularly to direction change lights.

En principe, les feux de signalisation arrière d'un véhicule comprennent une partie rouge correspondant à l'indication du freinage et une partie ambre correspon­dant aux changements de direction. A l'avant, le véhicule comporte seulement des phares et la partie ambre. Pour des raisons d'esthétique, on a tendance à regrouper derrière un diffuseur cristal le feu de changements de direction et le phare, toutefois à travers le diffuseur, on voit la partie ambre ce qui est inesthétique.In principle, the rear signal lights of a vehicle include a red part corresponding to the indication of braking and an amber part corresponding to changes in direction. At the front, the vehicle has only headlights and the amber part. For aesthetic reasons, we tend to group behind a crystal diffuser the direction change light and the lighthouse, however through the diffuser, we see the amber part which is unsightly.

On a proposé dans le brevet français 2 517 804, de remédier à cet inconvénient en réalisant un feu dans lequel en avant de la lampe, on dispose un réseau de len­tilles convergentes et en avant de celui-ci une plaque per­forée présentant des perforations tronconiques et dont la face tournée vers le diffuseur porte une couche réflectrice.It has been proposed in French patent 2,517,804, to remedy this drawback by producing a light in which in front of the lamp, there is a network of converging lenses and in front of it a perforated plate having frustoconical perforations and whose face facing the diffuser carries a reflective layer.

Dans une telle disposition, les lentilles conver­gentes doivent être disposées de manière à être alignées avec les trous tronconiques et pour que de l'extérieur la coloration ne soit pas visible il est également souhaitable que la face revêtue d'une couche réflectrice soit également constituée de lentilles divergentes.In such an arrangement, the converging lenses must be arranged so as to be aligned with the frustoconical holes and so that from the outside the coloring is not visible it is also desirable that the face coated with a reflective layer is also made up of divergent lenses.

Une telle disposition est relativement complexe et chère.Such an arrangement is relatively complex and expensive.

Dans le brevet français no 2 493 960 on a égale­ment proposé une disposition permettant de réaliser un feu qui à l'état inactif présente une coloration différente de celle obtenue lorsque le feu est éclairé. La disposition prévue dans ce brevet est assez voisine de celle décrite dans le brevet français 2 517 804 et prévoit en avant de la lampe un premier écran percé de trous et dont les surfa­ces pleines tournées du côté opposé à la lampe sont réflé­chissantes. Un second écran disposé devant le premier pré­sentant sur sa face interne une série de prismes.In French Patent No. 2,493,960 an arrangement for performing a fire has also been proposed that in the inactive state has a different coloring from that obtained when the light is illuminated. The arrangement provided in this patent is quite similar to that described in French patent 2,517,804 and provides in front of the lamp a first screen pierced with holes and whose solid surfaces turned on the side opposite to the lamp are reflective. A second screen arranged in front of the first having on its internal face a series of prisms.

Une telle disposition présente également l'in­convénient de nécessiter un traitement réfléchissant du premier écran ce qui est onéreux.Such an arrangement also has the drawback of requiring a reflective treatment of the first screen, which is expensive.

La technique antérieure connaît également le brevet allemand no 956.566 qui décrit un feu arrière de véhicule automobile comprenant un écran catadioptrique avec des surfaces planes et un écran intermédiaire disposé entre l'écran catadioptrique et la lampe, cet écran intermédiaire présentant des lentilles bi-connexes au droit des surfaces planes de l'écran catadioptrique afin de faire converger les rayons lumineux issus de la lampe vers lesdites surfaces planes.The prior art also known the German patent No. 956 566 which discloses a rear light motor vehicle comprising a catadioptric screen with planar surfaces and an intermediate screen disposed between the screen reflector and lamp, the intermediate screen having bi-related lenses to the right of the flat surfaces of the retro-reflecting screen in order to make the light rays coming from the lamp converge towards said flat surfaces.

Une telle disposition ne permet pas d'obtenir les résultats visés par la présente demande.Such a provision does not make it possible to obtain the results targeted by the present application.

L'un des buts de la présente invention est de réaliser un feu beaucoup plus simple à fabriquer et qui permet de l'extérieur de donner une impression d'unité avec un phare contigü.One of the aims of the present invention is to produce a light which is much simpler to manufacture and which allows the exterior to give an impression of unity with a contiguous headlight.

Les perfectionnements, selon l'invention, s'ap­pliquent plus particulièrement à des feux d'indication de changements de direction clignotants du type comprenant un réflecteur, une lampe à incandescence, un diffuseur mas­quant le réflecteur, des moyens pour colorer le faisceau lumineux issus de la lampe, un premier écran pour canaliser le faisceau lumineux vers l'extérieur, un second écran pour masquer, depuis l'extérieur lorsque la lampe n'est pas allu­mée, les moyens pour colorer le faisceau lumineux et disposé en avant du premier écran et sont caractérisés en ce que le premier écran présente sur sa face tournée en regard de la lampe une série de sillons concentriques et sur l'une des parties au moins de l'une de ses faces un réseau de lentilles en forme de calottes sphériques.The improvements according to the invention apply more particularly to flashing direction change indicator lights of the type comprising a reflector, an incandescent lamp, a diffuser masking the reflector, means for coloring the light beam coming from the lamp, a first screen for channeling the light beam towards the outside, a second screen for masking, from the outside when the lamp is not lit, the means for coloring the light beam and arranged in front of the first screen and are characterized in that the first screen has on its face turned opposite the lamp a series of concentric grooves and on one of the parts at least of one of its faces a network of lenses in the form of spherical caps.

Grâce à une telle disposition lorsque le feu n'est pas allumé, la coloration est parfaitement invisible, tandis que, lorsqu'il est allumé il présente une bonne in­tensité.Thanks to such an arrangement when the fire is not lit, the coloring is perfectly invisible, while, when it is lit, it has a good intensity.

De préférence, la face du premier écran tour­née en regard du second écran présente un réseau de lentil­les en forme de calottes sphériques, la totalité de la face tournée en regard de la lampe étant couverte par les sillons concentriques.Preferably, the face of the first screen turned opposite the second screen has a network of lenses in the form of spherical caps, the entire face turned opposite the lamp being covered by the concentric grooves.

Suivant une variante de réalisation, les sillons concentriques sont situés dans une partie du premier écran situé au droit de la lampe, le reste de la surface compor­tant un réseau de lentilles en forme de calottes sphériques, l'autre face étant plane.According to an alternative embodiment, the concentric grooves are located in a part of the first screen located to the right of the lamp, the rest of the surface comprising a network of lenses in the form of spherical caps, the other face being flat.

Suivant une caractéristique constructive, les sillons concentriques sont situés dans une partie du premier écran situé au droit de la lampe, le reste de la surface comportant un réseau de lentilles en forme de calottes sphé­riques, l'autre face comportant un réseau de calottes sphé­riques.According to a constructive characteristic, the concentric grooves are located in a part of the first screen located to the right of the lamp, the rest of the surface comprising a network of lenses in the form of spherical caps, the other face comprising a network of spherical caps.

De préférence, le second écran comporte sur sa face tournée en regard du premier écran, des prismes cadatioptriques affectant la forme de pyramides présentant trois faces latérales et dont les arêtes adjacentes à la base sont tronquées de manière à ménager entre les prismes des surfaces planes hexagonales, lesdites bases étant elles-­même hexagonales.Preferably, the second screen has on its side turned opposite the first screen, cadatioptic prisms affecting the shape of pyramids having three lateral faces and whose edges adjacent to the base are truncated so as to form between the prisms of the hexagonal flat surfaces , said bases themselves being hexagonal.

Enfin, les moyens de coloration du faisceau lumineux sont formés par une coloration d'une partie de la surface de la lampe.Finally, the means for coloring the light beam are formed by coloring part of the surface of the lamp.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et repré­sentés aux dessins annexés, dans lesquels :

The invention will now be described in more detail with reference to particular embodiments given by way of example only and shown in the accompanying drawings, in which:
  • Figure 1 is a plan view of a face of a first screen placed in front of the lamp.
  • Figure 2 is a plan view of the other side of the first screen.
  • Figure 3 is an enlarged plan view of another screen placed in front of the first screen.

  • Figure 6 is a sectional view along a third embodiment of the invention.
  • Figure 7 is a plan view of the side facing the lamp of the first screen.
  • Figure 8 is a sectional view of a last embodiment of the invention.

Le feu représenté à la figure 4 comprend une douille 1 destinée à être reliée à une source de courant électrique convenable et agencée pour recevoir le culot 2 d'une lampe électrique dont le ballon 3 présente une calot­te 4 teintée en ambre.The light shown in Figure 4 includes a socket 1 intended to be connected to a suitable source of electric current and arranged to receive the base 2 of an electric lamp whose balloon 3 has a cap 4 tinted in amber.

La douille est montée dans un réflecteur 5 argen­té intérieurement supportant deux écrans 6 et 7, un diffu­seur 8 en matière plastique transparente étant disposé de­vant l'ensemble.The socket is mounted in an internally silver reflector 5 supporting two screens 6 and 7, a diffuser 8 made of transparent plastic being placed in front of the assembly.

L'écran 6 (voir figure 2) comporte du côté de la lampe une série de sillons concentriques 10, tandis que l'autre face (voir figure 1) comporte des lentilles en forme de calottes sphériques 11. Ainsi, les rayons lumineux émis par les lampes sont canalisés vers l'extérieur.The screen 6 (see FIG. 2) comprises on the side of the lamp a series of concentric grooves 10, while the other face (see FIG. 1) comprises lenses in the form of spherical caps 11. Thus, the light rays emitted by the lamps are channeled outwards.

L'écran 7 présente, du côté du diffuseur 8, une face plane, tandis que de l'autre côté, comporte une succession de prismes catadioptriques 13 affectant la forme d'une pyramide présentant trois faces latérales et dont les arêtes adjacentes à la base sont tronquées de manière que ladite base détermine une surface hexagonale, les sommets étant tournés vers l'écran 6. Les prismes catadioptriques sont disposés afin de délimiter entre eux des surfaces planes hexagonales 14 parallèles à la face tournée vers le diffuseur 8.The screen 7 has, on the side of the diffuser 8, a flat face, while on the other side, comprises a succession of catadioptric prisms 13 affecting the shape of a pyramid having three lateral faces and whose edges adjacent to the base are truncated so that said base determines a hexagonal surface, the vertices being turned towards the screen 6. The catadioptric prisms are arranged in order to delimit between them hexagonal flat surfaces 14 parallel to the face turned towards the diffuser 8.

Les deux écrans 6 et 7 sont réalisés en matière plastique d'aspect cristal.The two screens 6 and 7 are made of crystal-like plastic.

Grâce à cette disposition, lorsque la lampe est éteinte de l'extérieur, l'ensemble du feu donne un aspect cristal, tandis que lorsque la lampe est allumée, les rayons lumineux concentrés par l'écran 6 traversent uniquement les surfaces hexagonales planes 14 avec la coloration corres­pondant à la calotte 4.Thanks to this arrangement, when the lamp is extinguished from the outside, the whole light gives a crystal appearance, while when the lamp is on, the light rays concentrated by the screen 6 pass only through the flat hexagonal surfaces 14 with the coloring corresponding to the cap 4.

A la figure 5, on a représenté une variante de réalisation. Sur cette figure, on a utilisé pour dési­gner les organes correspondant à ceux de la figure 4 les mêmes références mais affectées de la lettre "a".In Figure 5, there is shown an alternative embodiment. In this figure, the same references but assigned the letter " a " have been used to designate the members corresponding to those of FIG. 4.

Dans cette réalisation, on retrouve les mêmes dispositions que celles décrites pour la figure 4, toutefois le ballon 3a de la lampe est soit incolore, soit dépoli et il est prévu un capuchon 10 fixé sur le réflecteur 5a et qui vient coiffer ladite lampe. Le capuchon est coloré en ambre de sorte que les rayons lumineux décrits ou réflé­chis par le réflecteur 5a et qui traversent seulement les surfaces 14a, sont colorés.In this embodiment, there are the same provisions as described for Figure 4, however the ball 3a of the lamp is either colorless or frosted and there is provided a cap 10 attached to the reflector 5 has and which fits over said lamp . The cap is colored in amber so that the light rays described or reflected by the reflector 5 a and which only pass through the surfaces 14 a are colored.

Aux figures 6 et 7, on a représenté une varian­te de réalisation de l'invention. Dans ce mode de réalisa­tion, on a utilisé pour désigner les organes correspondants à ceux des figures 4 et 5 les mêmes références mais affec­tées de la lettre "b".In Figures 6 and 7, an alternative embodiment of the invention is shown. In this embodiment, the same references but assigned the letter " b " have been used to designate the members corresponding to those of FIGS. 4 and 5.

Dans cette réalisation, seul l'écran 6b diffère. La surface de l'écran 6b tournée en regard de l'écran 7b comporte un réseau de lentilles 11b en forme de calottes sphériques correspondant aux lentilles 11 montrées sur la figure 1. La face tournée vers la lampe 3b présente au droit de la calotte 4b des sillons concentriques 15, tandis que le reste de la surface est pourvue de lentilles en forme de calottes sphériques 16.In this embodiment, only the screen 6 b differs. The surface of the screen 6 b turned opposite the screen 7 b comprises a network of lenses 11 b in the form of spherical caps corresponding to the lenses 11 shown in FIG. 1. The face turned towards the lamp 3 b presents at right of the cap 4b of the concentric grooves 15, while the rest of the surface is provided with lenses in the form of spherical caps 16.

A la figure 8, on a représenté un dernier mode de réalisation de l'invention. A la figure 8, on a utilisé les mêmes références que celles utilisées pour les figures 4, 5 et 6 pour désigner les organes correspondants, mais affectées de la lettre "c".In Figure 8, there is shown a last embodiment of the invention. In FIG. 8, the same references have been used as those used for FIGS. 4, 5 and 6 to designate the corresponding members, but assigned the letter "c".

Dans cette variante, l'écran 6c présente du côté de la calotte 4c de la lampe 3c des sillons concentriques 15 du même type que ceux représentés à la figure 7, ces sillons s'étendant au droit de la calotte 4c de la lampe 3c, tandis que le reste de la surface est pourvue de calot­tes sphériques 16.In this variant, the screen 6 c has, on the side of the cap 4 c of the lamp 3 c, concentric grooves 15 of the same type as those shown in FIG. 7, these grooves extending in line with the cap 4 c of the lamp 3 c , while the rest of the surface is provided with spherical caps 16.

La face de l'écran 6c tournée vers l'écran 7c est plan.The face of the screen 6 c facing the screen 7 c is planar.

Bien entendu, les écrans 6a, 7a, 6b, 7b et 6c, 7c sont réalisés en matière plastique d'aspect cristal et on obtient avec cette combinaison les mêmes résultats qu'avec les différentes combinaisons précédentes.Of course, the screens 6 a , 7 a , 6 b , 7 b and 6 c , 7 c are made of plastic material with a crystal appearance and the same results are obtained with this combination as with the various preceding combinations.

Les diffuseurs 8, 8a, 8b et 8c peuvent comporter des lentilles sur la face interne ou la face externe pour distribuer la lumière selon une répartition spatiale désirée.The diffusers 8, 8 a , 8 b and 8 c may include lenses on the internal face or the external face to distribute the light according to a desired spatial distribution.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modification de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
