Description
L'invention vise des feux de signalisation de véhicules automobiles et plus particulièrement des feux de changements de direction.The invention relates to motor vehicle signaling lights 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 headlight, however through the diffuser, we see the amber part which is unsightly.
L'invention se rapporte à un feu qui, de l'extérieur, permet de donner une impression d'unité avec le phare contigu.The invention relates to a light which, from the outside, makes it possible to give an impression of unity with the adjoining lighthouse.
On a proposé dans le brevet français 2 517 804, un feu visant un tel but et 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.French patent 2,517,804 has proposed a light for such a purpose and 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 of which the side 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 complexe et chère.Such a provision is complex and expensive.
Dans le brevet français n° 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 n° 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, a provision has also been proposed making it possible to produce a fire which in the inactive state has a different coloring from that obtained when the fire is lit. The arrangement provided in this patent is quite similar to that described in French Patent No. 2,517,804 and provides in front of the lamp a first screen pierced with holes and whose solid surfaces facing the side opposite 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 n° 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-convexes 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 knows the German patent n ° 956.566 which describes a rear light of a motor vehicle comprising a retro-reflecting screen with flat surfaces and an intermediate screen arranged between the retro-reflecting screen and the lamp, this intermediate screen having bi-convex 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 de donner un aspect unitaire avec le phare voisin.Such an arrangement does not make it possible to give a unitary appearance with the neighboring lighthouse.
Le brevet allemand n° 1 655 784 vise un feu de signalisation qui comprend un premier écran disposé devant une lampe à incandescence qui présente, sur sa face tournée en regard de la lampe, une série de sillons concentriques et sur l'autre face des lentilles divergentes.German patent n ° 1 655 784 relates to a signaling light which comprises a first screen arranged in front of an incandescent lamp which has, on its face facing the lamp, a series of concentric grooves and on the other face of the lenses divergent.
Devant l'écran est disposé un écran transparent qui comporte des bandes opaques. Une telle réalisation présente l'inconvénient que l'écran est cher à réaliser et est inesthétique.In front of the screen is arranged a transparent screen which has opaque bands. Such an embodiment has the disadvantage that the screen is expensive to produce and is unsightly.
L'un des buts de la présente invention est de remédier aux inconvénients de la technique antérieure.One of the aims of the present invention is to remedy the drawbacks of the prior art.
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 les faisceaux lumineux issus de la lampe, un premier écran pour canaliser les faisceaux lumineux vers l'extérieur, un second écran pour masquer, depuis l'extérieur lorsque la lampe n'est pas allumée, les moyens pour colorer les faisceaux lumineux et disposé en avant du premier écran, ce dernier présentant 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, lesdits perfectionnements étant caractérisés en ce que le second écran comporte sur sa face tournée en regard du premier écran des prismes catadioptriques 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-mêmes hexagonales.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 beams coming from the lamp, a first screen for channeling the light beams towards the outside, a second screen for masking, from the outside when the lamp is not lit, the means for coloring the light beams and arranged in front of the first screen, the latter having on its face turned opposite the lamp, a series of concentric grooves and, on at least one of the parts of one of its faces, a network of lenses in the form of spherical caps, said improvements being characterized in that the second screen comprises on its face turned opposite the first screen catadioptric 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 flat surfaces hexagonal, said bases themselves being hexagonal.
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 le 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 facing the second screen has the network of lenses in the form of spherical caps, the entire face facing 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 plane.
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.
Enfin, les moyens de coloration des faisceaux lumineux sont formés par une coloration d'une partie de la surface de la lampe.Finally, the means for coloring the light beams are formed by coloring part of the surface of the lamp.

Les deux écrans 6 et 7 sont réalisés en matière plastique d'aspect cristal.The two
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
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.
