Abstract

Moulded, rose-tinted (32) front-glass (30) has moulded into its front face regularly spaced flush-fitting, horizontal or vertical, translucent red bars (34). Opt., the inserts form a chequerboard pattern. The visible area thus presets alternating rose (Z1) and red (Z2) zones. The rear face presents a corresponding pattern of lenses (36) and prisms (38), red inserts all being shields by prisms which reflect most of the incident light (10,20). This beam passes mainly through the other zones (Z1), aided by concentrating lenses. A Fresnel lens (50) deflects unreflected light. Aided, opt., by a corrective screen (40), the lit lamp appears nearly white, functioning as a reversing light, but appears red when unlit. Opt., with an amber-tinted screen (40), it acts as a direction indicator.

Description

La présente invention concerne d'une façon générale les feux de signalisation de véhicules automobiles, et plus particulièrement un feu de signalisation susceptible d'émettre un rayonnement sensiblement incolore, ou d'une première teinte, tout en présentant, lorsqu'il est éteint, un aspect d'une deuxième teinte.The present invention relates generally to the signaling lights of motor vehicles, and more particularly to a signaling light capable of emitting substantially colorless radiation, or of a first shade, while having, when it is switched off, an aspect of a second shade.

Par exemple, mais non limitativement, il peut s'agir d'un feu de recul émettant une lumière blanche et d'aspect rouge ou ambré lorsqu'il est éteint, ou d'un feu clignotant indicateur de changement de direction émettant une lumière ambre mais d'aspect rouge lorsqu'il est éteint.For example, but not limited to, it may be a reversing light emitting a white light and of red or amber appearance when it is off, or a flashing light indicating a change of direction emitting an amber light but red when it is off.

On connaît déjà dans la technique antérieure ce genre de feu, dont l'objet principal est de se marier avec des feux voisins en particulier d'aspect rouge lorsqu'ils sont éteints, tels que des feux de position arrière ou des feux stop(indicateurs de freinage).This type of light is already known in the prior art, the main object of which is to marry neighboring lights, in particular red in appearance when they are extinguished, such as rear position lights or stop lights (indicators braking).

Ainsi le document DE-A-31 30 085 décrit un feu de signalisation comprenant une source lumineuse, des moyens pour diriger le flux lumineux émis par la source vers un écran intermédiaire, et un voyant de fermeture disposé le long et à l'extérieur de l'écran intermédiaire.Document DE-A-31 30 085 thus describes a signaling light comprising a light source, means for directing the light flux emitted by the source towards an intermediate screen, and a closing indicator disposed along and outside of the intermediate screen.

L'écran intermédiaire comporte des éléments optiques qui amènent la lumière à converger vers des passages de lumière s'étendant entre des zones colorées rapportées sur la face extérieure du voyant. Le voyant comporte sur sa face interne des éléments de déviation ou de diffusion de la lumière.The intermediate screen comprises optical elements which cause the light to converge towards light passages extending between colored zones added on the external face of the indicator. The indicator light has on its internal face elements for deflecting or diffusing light.

On comprend que, si le matériau de l'écran intermédiaire est transparent incolore, si les zones colorées rapportées sont rouges et si le matériau du voyant entre lesdites zones colorées est incolore, l'aspect du feu lorsqu'il est éteint est généralement rouge, tandis que le rayonnement émis est sensiblement incolore. Pour renforcer l'aspect rouge de ce feu lorsqu'il est éteint, des cloisons séparatrices sont prévues entre l'écran et le voyant, généralement transversalement aux plans de ces éléments.It is understood that, if the material of the intermediate screen is colorless transparent, if the colored areas reported are red and if the material of the indicator light between said colored areas is colorless, the appearance of the fire when it is extinguished is generally red, while the radiation emitted is substantially colorless. To reinforce the red aspect of this light when it is extinguished, dividing partitions are provided between the screen and the indicator, generally transverse to the planes of these elements.

Un tel feu est relativement coûteux et complexe à réaliser, nécessitant un écran, un voyant de conception spécifique avec deux matières, et une pièce définissant les cloisons.Such a fire is relatively expensive and complex to produce, requiring a screen, a sight glass of specific design with two materials, and a part defining the partitions.

La présente invention vise à proposer un feu de signalisation du type précité, qui soit plus simple et économique à réaliser, tout en offrant des qualités satisfaisantes en matière de restitution de la couleur du rayonnement et de la couleur du voyant éteint.The present invention aims to propose a signaling light of the aforementioned type, which is simpler and economical to produce, while offering satisfactory qualities in terms of restitution of the color of the radiation and of the color of the light off.

Ainsi la présente invention concerne un feu de signalisation notamment pour véhicule automobile, du type comprenant une source lumineuse, un voyant de fermeture et des premiers moyens optiques pour diriger le flux lumineux émis par la source sensiblement transversalement au voyant de fermeture, le voyant comprenant des premières zones d'une première matière et des secondes zones d'une seconde matière encastrée dans la première matière sur la face externe du voyant, la seconde matière étant une matière transparente d'une teinte sombre voisine de celle d'un feu de signalisation adjacent, et des seconds moyens optiques pour empêcher la lumière issue des premiers moyens de traverser ladite seconde matière, caractérisé en ce que la première matière est une matière transparente d'une teinte éclaircie par rapport à la teinte sombre, et en ce que les seconds moyens optiques comprennent des éléments prismatiques formés par la première matière sur la face interne du voyant en arrière desdites secondes zones de la seconde matière.

  • la première matière définit également, entre les éléments prismatiques adjacents, des éléments pour diffuser la lumière tout en la concentrant sur lesdites premières zones.
  • la première teinte est rouge et la seconde teinte est rose.
  • le feu comprend en outre un écran intermédiaire entre la source et le voyant, ledit écran étant apte à teinter le rayonnement issu de la source.
  • le voyant est réalisé par moulage de matière plastique, caractérisé en ce que la seconde matière est surmoulée sur la première matière.
  • le voyant est réalisé par moulage de matière plastique, caractérisé en ce que la première matière est surmoulée sur la seconde matière.
Thus the present invention relates to a signaling light in particular for a motor vehicle, of the type comprising a light source, a closing light and first optical means for directing the light flux emitted by the source substantially transversely to the closing light, the light comprising first zones of a first material and second zones of a second material embedded in the first material on the external face of the sight glass, the second material being a transparent material of a dark shade close to that of an adjacent traffic light , and second optical means for preventing light from the first means from passing through said second material, characterized in that the first material is a transparent material of a shade lightened with respect to the dark shade, and in that the second means optics include prismatic elements formed by the first material on the inner face of the v going behind said second areas of the second material.
  • the first material also defines, between the adjacent prismatic elements, elements for diffusing the light while concentrating it on said first zones.
  • the first shade is red and the second shade is pink.
  • the fire further comprises an intermediate screen between the source and the indicator, said screen being capable of tinting the radiation coming from the source.
  • the sight glass is made by molding plastic material, characterized in that the second material is overmolded on the first material.
  • the sight glass is made by molding plastic material, characterized in that the first material is overmolded on the second material.

L'invention propose également un procédé de fabrication par moulage du voyant d'un feu de signalisation tel que défini ci-dessus, caractérisé en ce qu'il comprend les étapes consistant à :

  • mouler la seconde matière d'une seule pièce avec au moins un voyant d'un feu de signalisation adjacent, et
  • surmouler la première matière sur la seconde matière.
  • Avantageusement, la seconde matière forme une grille.
The invention also proposes a method of manufacturing by molding the indicator of a signaling light as defined above, characterized in that it comprises the steps consisting in:
  • mold the second material in one piece with at least one indicator of an adjacent traffic light, and
  • overmolding the first material on the second material.
  • Advantageously, the second material forms a grid.

D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante de formes de réalisation préférées de celle-ci, donnée à titre d'exemple non limitatif et faite en référence au dessin annexé, sur lequel :

  • la figure 1 est une vue en coupe verticale axiale d'un feu de signalisation selon l'invention, et
  • la figure 2 est une vue en coupe transversale d'un voyant du feu de signalisation de la figure 1 associé au voyant d'un feu adjacent.
Other aspects, aims and advantages of the present invention will appear better on reading the following detailed description of preferred embodiments thereof, given by way of nonlimiting example and made with reference to the appended drawing, in which :
  • FIG. 1 is a view in axial vertical section of a signaling light according to the invention, and
  • Figure 2 is a cross-sectional view of a signal light of Figure 1 associated with the light of an adjacent light.

En référence tout d'abord à la figure 1, on a représenté schématiquement un feu de signalisation qui comprend une source lumineuse 10, typiquement une lampe à filament normalisée, un réflecteur 20 du genre parabolique défini par le socle du feu et destiné à diriger la lumière réfléchie par lui selon une direction générale d'émission, et un voyant 30.Referring firstly to Figure 1, there is shown schematically a signaling light which comprises a light source 10, typically a standard filament lamp, a reflector 20 of the parabolic type defined by the base of the light and intended to direct the light reflected by it in a general direction of emission, and a light 30.

Comme on le verra plus loin, le feu peut comprendre optionnellement un écran intermédiaire 40 et une lentille de Fresnel 50, représentés en traits mixtes.As will be seen below, the light can optionally include an intermediate screen 40 and a Fresnel lens 50, shown in phantom.

Le voyant 30 est réalisé avec deux matières translucides distinctes. Dans une première matière 32, en l'espèce de teinte rose, sont encastrées des zones de seconde matière 34, de teinte rouge. Ainsi, sur sa face externe, le voyant comporte des premières zones Z1 dans lesquelles la première matière est apparente, et des secondes zones Z2 dans lesquelles la seconde matière est apparente, les faces externes des zones de première et de seconde matière étant affleurantes les unes avec les autres de manière à satisfaire aux règlements.The sight glass 30 is made with two distinct translucent materials. In a first material 32, in this case of pink shade, are embedded areas of second material 34, of red shade. Thus, on its external face, the sight glass comprises first zones Z1 in which the first material is visible, and second zones Z2 in which the second material is visible, the external faces of the zones of first and second material being flush with each other with others so as to meet regulations.

Les zones encastrées de la seconde matière s'étendent sur une partie seulement de l'épaisseur du voyant, si bien que la face interne de celui-ci est définie par la seule première matière. Cette face interne comprend deux types d'aménagements optiques. Au droit des zones Z2, il est prévu des éléments prismatiques saillants 38 comportant des faces droites inclinées par exemple à environ 45° par rapport à la direction générale du rayonnement. Au droit des zones Z1, il est prévu des lentilles convexes 36 aptes à diffuser la lumière issue du réflecteur 20 tout en la concentrant dans les fenêtres de sortie de lumière définies par les zones Z1.The recessed areas of the second material extend over only part of the thickness of the sight glass, so that the internal face of the latter is defined by the only first material. This internal face includes two types of optical arrangements. In line with the zones Z2, prismatic protruding elements 38 are provided comprising straight faces inclined for example at about 45 ° relative to the general direction of the radiation. In line with the zones Z1, there are provided convex lenses 36 capable of diffusing the light coming from the reflector 20 while concentrating it in the light output windows defined by the zones Z1.

Lorsque le feu est éteint, le mélange des zones Z2 de couleur rouge et des zones Z1 de couleur rose (en arrière desquelles se trouve l'espace intérieur du feu, formant une cavité sombre), donne au feu un aspect général de teinte rouge très voisine de celle d'un autre feu, par exemple un feu de position et/ou un feu stop à voyant rouge, appartenant au même bloc optique.When the fire is out, the mixture of zones Z2 of red color and zones Z1 of pink color (behind which is the interior space of the fire, forming a dark cavity), gives the fire a general appearance of very red tint close to that of another light, for example a position light and / or a stop light with red indicator, belonging to the same optical unit.

Lorsque le feu est allumé, la lumière incolore issue du miroir et incidente sur les lentilles 36 traverse les zones Z1 peu teintées, et reste donc sensiblement incolore, pour former un faisceau de feu de recul. La lumière issue du miroir et incidente sur les prismes 38 est réfléchie en proportion très importante par ces prismes, pour ainsi minimiser la quantité de lumière susceptible de traverser la seconde matière 34 et éviter de polluer la lumière par un rayonnement coloré en rouge.When the fire is on, the colorless light coming from the mirror and incident on the lenses 36 crosses the lightly tinted zones Z1, and therefore remains substantially colorless, to form a reversing light beam. The light coming from the mirror and incident on the prisms 38 is reflected in very large proportion by these prisms, so as to minimize the amount of light likely to pass through the second material 34 and to avoid polluting the light by a radiation colored in red.

On notera que les zones Z1 et Z2 peuvent se répartir selon tout motif approprié, de préférence régulier. Il peut s'agir notamment de bandes alternées verticales ou horizontales. En variante, les zones Z2 peuvent définir un maillage carré, entre les mailles venant se placer des pavés, carrés ou rectangulaires ou de toute autre forme géométrique, formant les zones Z1, ou réciproquement.It will be noted that the zones Z1 and Z2 can be distributed according to any suitable pattern, preferably regular. They may in particular be alternating vertical or horizontal bands. As a variant, the zones Z2 can define a square mesh, between the meshes from which paving stones, square or rectangular or any other geometric shape are placed, forming the zones Z1, or vice versa.

Bien entendu, la forme et la disposition des éléments optiques 36, 38 est adaptée au cas par cas.Of course, the shape and arrangement of the optical elements 36, 38 is adapted to the case by case.

Ainsi, dans le cas où les zones Z2 sont définies de préférence par des lignes, éventuellement entrecroisées, les éléments optiques 38 sont des stries prismatiques à deux faces.Thus, in the case where the zones Z2 are preferably defined by lines, possibly intersecting, the optical elements 38 are prismatic streaks with two faces.

Dans le cas où les zones Z1 sont des pavés, les éléments 36 sont de préférence des billes ou des tores.In the case where the zones Z1 are blocks, the elements 36 are preferably balls or tori.

Dans le cas où les zones Z1 et Z2 zont des bandes alternées, les éléments 38 sont de préférence des stries prismatiques, tandis que les éléments 36 sont des stries cylindriques.In the case where the zones Z1 and Z2 have alternating bands, the elements 38 are preferably prismatic streaks, while the elements 36 are cylindrical streaks.

Le voyant 30 est réalisé avantageusement par moulage par injection, la première matière étant surmoulée sur la seconde ou réciproquement. On peut notamment avoir recours aux techniques de moulage avec presse multicouleurs, en reprises, etc.The sight glass 30 is advantageously produced by injection molding, the first material being overmolded on the second or vice versa. One can in particular have recourse to the techniques of molding with multicolour press, in recoveries, etc.

L'écran intermédiaire optionnel 40 peut avoir plusieurs objectifs. Le premier est de teinter le cas échéant le rayonnement issu de la source et du miroir, soit pour neutraliser les effets du léger rosissement de la lumière lors de son passage à travers la première matière du voyant, soit encore pour donner à la lumière une couleur ambre, lorsque le feu est un feu clignotant indicateur de changement de direction.The optional intermediate screen 40 can have several objectives. The first is to tint, if necessary, the radiation from the source and the mirror, either to neutralize the effects of the slight pinking of light when it passes through the first material. of the indicator, or again to give the light an amber color, when the light is a flashing light indicating a change of direction.

L'écran intermédiaire 40 peut également comporter des aménagements optiques destinés à concentrer la lumière issue du miroir vers les zones Z1 de passage de la lumière du voyant.The intermediate screen 40 may also include optical arrangements intended to concentrate the light coming from the mirror towards the zones Z1 of passage of the light from the indicator light.

La lentille de Fresnel 50 est destinée à minimiser les effets de la lumière directe multidirectionnelle émise par la lampe 10 en direction du voyant. En effet une lumière fortement inclinée par rapport à la direction générale d'émission serait susceptible de traverser les zones Z2 de seconde matière, pour donner au faisceau une teinte rouge perceptible.The Fresnel lens 50 is intended to minimize the effects of multidirectional direct light emitted by the lamp 10 in the direction of the indicator. Indeed, a light strongly inclined relative to the general direction of emission would be likely to pass through the zones Z2 of second material, to give the beam a perceptible red tint.

Selon un autre aspect de la présente invention, et maintenant en référence à la figure 2, lorsque le feu de signalisation décrit ci-dessus appartient à un bloc optique arrière comportant plusieurs plages éclairantes adjacentes, il est très avantageux de mouler la seconde matière 34 en une grille (à bandes parallèles ou croisées) en même temps qu'un voyant V d'un feu adjacent de couleur rouge, tel qu'un feu de position ou un feu stop. Ensuite, la première matière est surmoulée sur la seconde matière, pour former le voyant 30.According to another aspect of the present invention, and now with reference to FIG. 2, when the signaling light described above belongs to a rear optical unit comprising several adjacent illuminating surfaces, it is very advantageous to mold the second material 34 into a grid (with parallel or crossed bands) at the same time as a warning light V of an adjacent red light, such as a position or stop light. Then, the first material is molded onto the second material, to form the sight glass 30.

Bien entendu, la présente invention n'est nullement limitée aux formes de réalisation décrites et représentées, mais l'homme de l'art saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is not limited to the embodiments described and shown, but those skilled in the art will be able to make any variant or modification in accordance with his spirit.
