Description

La présente invention concerne d'une façon générale les feux de signalisation de véhicules, notamment de véhicules automobiles, et en particulier un feu dans lequel une partie du flux lumineux engendré par la source lumineuse est émis par le feu en direction de la région latérale du véhicule, pour qu'il tienne lieu à la fois, avec une même source lumineuse, de feu de signalisation axial (feu de position) et de marqueur latéral.The present invention relates generally to the signaling lights of vehicles, in particular of motor vehicles, and in particular a light in which part of the light flux generated by the light source is emitted by the light in the direction of the lateral region of the vehicle, so that it takes the place simultaneously, with the same light source, of axial signaling light (position light) and lateral marker.

Une telle fonction de marquage latéral, obligatoire dans certains pays, a pour objet principal de signaler la présence du véhicule lorsque, de nuit, il est observé latéralement.The main purpose of such a lateral marking function, which is compulsory in certain countries, is to indicate the presence of the vehicle when, at night, it is observed from the side.

On connaît déjà dans la technique antérieure un certain nombre de feux de signalisation remplissant cette double fonction.A number of signal lights fulfilling this dual function are already known in the prior art.

En partilulier, la demande brevet français FR-A 2 378 234 publié au nom de la Demanderesse propose un feu de signalisation dans lequel une lampe mono- filament unique est associée à un premier réflecteur, destiné à créer un faisceau lumineux axial pour une fonction feu de position, et à un second réflecteur disposé du côté intérieur de la lampe et destiné à renvoyer vers le côté opposé, c'est-à-dire vers la région latérale du véhicule, une partie des rayons lumineux émis par la lampe, dans le but de remplir une fonction de marqueur latéral. A cet effet, un élément catadioptrique, qui est prévu dans la région latérale de ce feu et qui ferait normalement obstacle à ce faisceau latéral, est modifié pour laisser passer celui-ci, en le diffusant.In particular, the French patent application FR-A 2 378 234 published in the name of the Applicant proposes a signaling light in which a single monofilament lamp is associated with a first reflector, intended to create an axial light beam for a light function position, and to a second reflector arranged on the interior side of the lamp and intended to return towards the opposite side, that is to say towards the lateral region of the vehicle, a part of the light rays emitted by the lamp, in the purpose of performing a side marker function. To this end, a catadioptric element, which is provided in the lateral region of this light and which would normally obstruct this lateral beam, is modified to let it pass, by diffusing it.

Un tel agencement présente cependant un certain nombre d'inconvénients. D'une part, le fait de prévoir un élément catadioptrique de conception spéciale peut s'avérer coûteux. D'autre part, pour que le réflecteur de faisceau axial n'entrave pas le passage du faisceau latéral, il est nécessaire que sa profondeur soit réduite, au détriment de l'intensité et de la visibilité du flux lumineux de feu de position.However, such an arrangement has a number of drawbacks. On the one hand, the fact of providing a catadioptric element of special design can prove to be costly. On the other hand, so that the axial beam reflector does not obstruct the passage of the lateral beam, it is necessary that its depth be reduced, to the detriment of the intensity and visibility of the position light light flux.

On connaît en outre par la demande de brevet français N° 2 177 382 un feu de signalisation pour véhicule qui comprend une source lumineuse unique, un premier réflecteur de très petite taille destiné à créer un faisceau axial (fonction feu de position), et un second réflecteur prévu latéralement sur la paroi intérieure du feu, afin de renvoyer une partie des rayons lumineux vers le côté du véhicule, à des fins de marquage latéral. Dans ce cas, on a évité que l'élément catadioptrique latéral constitue un obstacle au faisceau latéral en reportant ce dernier bien en arrière de la lampe. Ce type de feu présente un premier inconvénient selon lequel le faisceau axial de la fonction feu de position est d'une intensité limitée, du fait des dimensions extrêmement réduites du réflecteur associé. Par ailleurs, la disposition des éléments constitutifs est telle que le feu occupe nécessairement une grande profondeur, et qu'il ne saurait en aucun cas être adapté aux blocs de feux de faible profondeur (profil plat) tels que souhaités actuellement sur le marché. Enfin, dans ce type de feu, il est nécessaire de prévoir deux éléments réflecteurs distincts, ce qui aboutit à une structure compliquée et onéreuse.Also known from French patent application No. 2 177 382 is a signaling light for a vehicle which comprises a single light source, a first reflector of very small size intended to create an axial beam (position light function), and a second reflector provided laterally on the interior wall of the light, in order to return part of the light rays to the side of the vehicle, for the purpose of lateral marking. In this case, it was avoided that the lateral catadioptric element constitutes an obstacle to the lateral beam by deferring the latter well behind the lamp. This type of light has a first drawback that the axial beam of the position light function is of limited intensity, due to the extremely small dimensions of the associated reflector. Furthermore, the arrangement of the constituent elements is such that the light necessarily occupies a great depth, and that it can in no case be adapted to light blocks of shallow depth (flat profile) as currently desired on the market. Finally, in this type of light, it is necessary to provide two separate reflective elements, which results in a complicated and expensive structure.

D'une façon plus générale, dans un feu de position plat disposé en coin et comprenant un réflecteur axial relativement profond et un élément catadioptrique agencé latéralement, si l'on souhaite donner à un tel feu une fonction de marqueur latéral à partir du rayonnement lumineux émis par le filament de feu de position, il est nécessaire, outre l'agencement éventuel d'un réfelcteur latéral additionnel approprié, de ménager une fenêtre dans le réflecteur axial ainsi que dans l'élément catadioptrique, ou au moins de modifier ce dernier. Cela est désavantageux principalement pour deux raisons: tout d'abord, le fait de ménager une fenêtre dans le réflecteur axial est à l'origine d'un trou noir dans l'image projetée du feu, ce que l'on ne souhaite pas; de plus, la modification ou le perçage de l'élément catadioptrique rend celui-ci plus difficilement conforme aux règlements, ou encore donne à son aspect une discontinuité indésirable du point de vue esthétique.More generally, in a flat position light arranged in a corner and comprising a relatively deep axial reflector and a retro-reflecting element arranged laterally, if it is desired to give such a light a function of lateral marker from the light radiation emitted by the position light filament, it is necessary, in addition to the possible arrangement of an appropriate additional lateral reflector, to provide a window in the axial reflector as well as in the retro-reflecting element, or at least to modify the latter. This is disadvantageous mainly for two reasons: firstly, the fact of leaving a window in the axial reflector is the source of a black hole in the projected image of the fire, which is not desirable; in addition, the modification or drilling of the retro-reflecting element makes it more difficult to comply with the regulations, or even gives its appearance an undesirable discontinuity from the aesthetic point of view.

La présente invention vise à pallier ces inconvénients de l'art antérieur et à proposer un feu de signalisation pour véhicule qui, tout en étant de profondeur limitée, puisse assurer avec une grande efficacité à la fois la fonction de feu de position axial et la fonction de marquer latéral.The present invention aims to overcome these drawbacks of the prior art and to propose a signaling light for a vehicle which, while being of limited depth, can ensure with great efficiency both the function of axial position light and the function to mark lateral.

A cet effet, l'invention concerne un feu axial et latéral de signalisation de véhicule comprenant un filament lumineux, un réflecteur, et une glace de fermeture (ou globe de fermeture) comportant une partie frontale et une partie latérale séparées par une région de coin, caractérisé en ce que le réflecteur comprend une première partie réfléchissante, destinée à renvoyer les rayons lumineux émis par le filament sensiblement dans la direction axiale du véhi- vule, et une seconde partie réfléchissante destinée à renvoyer les rayons lumineux émis par le filament vers la région de coin de la glace de fermeture, dans une direction sensiblement transversale, ladite région de coin comportant à sa surface intérieure des éléments réfracteurs de manière à répartir le flux lumineux réfléchi par la seconde partie du réflecteur sur la région latérale du véhicule.To this end, the invention relates to an axial and lateral vehicle signaling light comprising a luminous filament, a reflector, and a closing glass (or closing globe) comprising a front part and a side part separated by a corner region. , characterized in that the reflector comprises a first reflecting part, intended to return the light rays emitted by the filament substantially in the axial direction of the vehicle, and a second reflecting part intended to return the light rays emitted by the filament towards the corner region of the closing glass, in a substantially transverse direction, said corner region comprising on its inner surface refracting elements so as to distribute the light flux reflected by the second part of the reflector over the lateral region of the vehicle.

De façon préférée, le feu comprend en outre des éléments réfracteurs (18) prévus sur la partie frontale (16a) de la glace de fermeture pour assurer une diffusion des rayons lumineux s'étendant dans la direction axiale du véhicule.Preferably, the light further comprises refracting elements (18) provided on the front part (16a) of the closing glass to ensure diffusion of the light rays extending in the axial direction of the vehicle.

D'autres caractéristiques et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante de modes de réalisation préférés de celle-ci, donnée à titre d'exemple et faite en référence au dessin annexé, sur lequel :

  • . la figure 1 est une vue de dessus en coupe d'un feu de coin selon un premier mode de réalisation de l'invention, et
  • . la figure 2 est une vue de dessus en coupe d'une autre réalisation d'un feu de coin selon l'invention.
Other characteristics and advantages of the present invention will appear better on reading the following detailed description of preferred embodiments thereof, given by way of example and made with reference to the appended drawing, in which:
  • . FIG. 1 is a top view in section of a corner light according to a first embodiment of the invention, and
  • . Figure 2 is a top view in section of another embodiment of a corner light according to the invention.

En référence à la figure 1, on a représenté partiellement un bloc de feux de signalisation arrière gauche d'un véhicule automobile. Ce bloc comprend conventionnellement une succession horizontale de feux de signalisation tels que feux de position, feux clignotants, feux stop, feux de recul, etc. Dans le présent exemple, le feu de position est situé à l'extrême gauche du bloc.Referring to Figure 1, there is partially shown a block of left rear signal lights of a motor vehicle. This block conventionally comprises a horizontal succession of signaling lights such as position lights, flashing lights, brake lights, reversing lights, etc. In the present example, the position light is located at the far left of the block.

Par ailleurs, l'invention s'applique tout particulièrement aux feux ou blocs de feux dits "en retour d'aille", c'est-à-dire que la glace de fermeture est incurvée de manière à substantiellement épouser la forme du coin associé du véhicule.Furthermore, the invention applies very particularly to lights or blocks of lights called "back flap", that is to say that the closing glass is curved so as to substantially match the shape of the associated corner of the vehicle.

Selon l'invention, le feu de position est agencé pour effectuer une signalisation dans l'axe du véhicule (fonction feu de position) et une signalisation latérale du véhicule. Plus précisément, le feu représenté comprend une lampe 10 comportant un filament unique 12, un réflecteur 14 destiné à renvoyer, selon des trajets spécifiques expliqués plus loin, la lumière émise par le filament 12, et une glace (ou globe) de fermeture 16, par exemple colorée. La glace de fermeture 16 comprend une première partie 16a s'étendant à l'arrière du véhicule, et une seconde partie 16b s'étendant sur le côté du véhicule, une partie incurvée 16c formant coin reliant les deux parties 16a et 16b. Enfin le bloc de feux comprend un élément catadioptrique latéral schématiquement indiqué en 19. On peut noter ici que, du fait de la conception généralement plate du bloc de feux envisagé, l'élément catadioptrique 19 s'étend sensiblement à la hauteur de la lampe 10 du feu, et qu'il est impossible de le reporter plus en avant du véhicule (vers le haut sur la figure 1).According to the invention, the position light is arranged to carry out signaling in the axis of the vehicle (position light function) and lateral signaling of the vehicle. More precisely, the light shown comprises a lamp 10 comprising a single filament 12, a reflector 14 intended to return, according to specific paths explained below, the light emitted by the filament 12, and a closing glass (or globe) 16, for example colored. The closing glass 16 comprises a first part 16a extending at the rear of the vehicle, and a second part 16b extending on the side of the vehicle, a curved part 16c forming a corner connecting the two parts 16a and 16b. Finally the block of lights comprises a lateral retro-reflecting element schematically indicated at 19. It can be noted here that, due to the generally flat design of the envisaged block of lights, the retro-reflecting element 19 extends substantially at the height of the lamp 10 fire, and it is impossible to carry it further forward of the vehicle (upwards in Figure 1).

Le réflecteur 14 est constitué par une première partie 14a de forme parabolique dont l'axe est sensiblement aligné avec l'axe du véhicule, et dont le foyer est situé approximativement à l'emplacement du filament 12. Cette partie réfléchissante 14a est agencée pour créer un faisceau de rayons parallèles, tels qu'indiqués en 20 et 22, s'étendant vers l'arrière du véhicule et destiné à remplir la fonction feu de position. A cet égard, on a prévu sur la surface intérieure des parties 16a et 16c de la glace de fermeture 16, d'une manière connue en soi, des éléments réfracteurs 18, dans le présent exemple des billes sensiblement hémisphériques, destinés à donner aux rayons du faisceau axial de feu de position une légère déviation. On pourra bien entendu faire appel à tout autre type d'irrégularité de surface pour obtenir ce résultat.The reflector 14 is constituted by a first part 14a of parabolic shape, the axis of which is substantially aligned with the axis of the vehicle, and the focal point of which is located approximately at the location of the filament 12. This reflecting part 14a is arranged to create a beam of parallel rays, as indicated in 20 and 22, extending towards the rear of the vehicle and intended to fulfill the position light function. In this regard, there are provided on the inner surface of the parts 16a and 16c of the closing glass 16, in a manner known per se, refracting elements 18, in the present example substantially hemispherical balls, intended to give the rays of the axial beam of position light a slight deviation. We can of course use any other type of surface irregularity to obtain this result.

Le réflecteur 14 comprend en outre une seconde partie 14b, dans le cas présent unitaire et sans discontinuité avec la première partie 14a, qui est focalisée approximativement sur le filament 12. La partie réfléchissante 14b correspond à la région de la joue latérale intérieure du réflecteur 14, et est destinée à renvoyer les rayons qui sont émis latéralement par le filament 12 vers la région de coin du feu, c'est-à-dire sensiblement vers l'espace libre entre le bord d'extrémité libre 14c de la partie 14a du réflecteur et la région du coin 16c de la glace de fermeture 16.The reflector 14 further comprises a second part 14b, in this case unitary and without discontinuity with the first part 14a, which is approximately focused on the filament 12. The reflecting part 14b corresponds to the region of the inner lateral cheek of the reflector 14 , and is intended to return the rays which are emitted laterally by the filament 12 towards the corner of the fire corner, that is to say substantially towards the free space between the free end edge 14c of the part 14a of the reflector and the region of the corner 16c of the closing glass 16.

On a représenté sur la figure 1 deux rayons réfléchis 24 et 26 légèrement convergents. Il est bien entendu que l'on adaptera la zone réfléchissante 14b en fonction de chaque cas, de manière à ce que majeure partie du faisceau réfléchi qu'elle crée rencontre la zone du coin 16c de la glace de fermeture. Ainsi, on pourra donner à la partie 14b une forme parabolique, elliptique, etc., focalisée approximativement sur la filament 12.There is shown in Figure 1 two reflected rays 24 and 26 slightly convergent. It is understood that the reflecting zone 14b will be adapted as a function of each case, so that most of the reflected beam which it creates meets the zone of the corner 16c of the closing glass. Thus, part 14b can be given a parabolic, elliptical, etc. shape, focused approximately on the filament 12.

La partie réfléchissante 14b crée ainsi un faisceau latéral dont la concentration en énergie lumineuse est relativement élevée, et les rayons arrivant dans la région 16c sont déviés comme indiqué par les éléments réfracteurs 18 de manière à obtenir, dans la région latérale du véhicule, une caractéristique photométrique conforme à la fonction de marqueur latéral.The reflecting part 14b thus creates a lateral beam whose light energy concentration is relatively high, and the rays arriving in the region 16c are deflected as indicated by the refracting elements 18 so as to obtain, in the lateral region of the vehicle, a characteristic photometric according to the function of lateral marker.

En particulier, on agencera les éléments réfracteurs 18 de manière à ce que l'angle de visibilité minimal vers l'extrémité opposée du véhicule, en l'occu- rence vers l'avant, soit respecté. A titre d'exemple, un tel angle peut avoir une valeur de l'ordre de 45°, valeur généralement imposée par des règlements.In particular, the refracting elements 18 will be arranged so that the minimum angle of visibility towards the opposite end of the vehicle, in this case towards the front, is respected. For example, such an angle can have a value of the order of 45 °, a value generally imposed by regulations.

Ainsi on réalise un feu à double fonction, à savoir feu de position axial et marqueur latéral, en utilisant de façon avantageuse une région du réflecteur (partie 14b) qui n'est pas spécialement critique pour la qualité du faisceau de feu de position, pour créer un faisceau auxiliaire relativement concentré vers un petit espace libre laissé entre le bord libre 14c dudit réflecteur et la glace de fermeture. Un autre avantage réside dans le fait que les irrégularités de surface qui sont normalement prévues pour la diffusion du faisceau axial de feu de position sont directement utilisées, sans agencement additionnel, pour obtenir une déviation de ce faisceau auxiliaire, par exemple de manière à satisfaire aux normes de photométrie imposées pour les marqueurs latéraux.Thus a dual function light, namely an axial position light and a side marker, is produced, advantageously using a region of the reflector (part 14b) which is not particularly critical for the quality of the position light beam, for creating a relatively concentrated auxiliary beam towards a small free space left between the free edge 14c of said reflector and the closing glass. Another advantage lies in the fact that the surface irregularities which are normally provided for the diffusion of the axial beam of the position light are directly used, without additional arrangement, to obtain a deflection of this auxiliary beam, for example so as to satisfy the photometry standards imposed for side markers.

Enfin on peut noter que la joue extérieure de la partie réfléchissante 14a et l'élément catadioptrique 19 ne sont aucunement gênants pour la création du faisceau de la fonction marqueur latéral. Ainsi, la parabole 14a peut conserver une forme relativement refermée, au profit de l'intensité du faisceau axial de feu de position, et il n'est pas nécessaire de modifier ou de déplacer l'élément catadioptrique 19. En effet, ces deux organes du feu sont contournés par le faisceau latéral. A cet égard, on peut rappeler que, dans les blocs de feux de profil plat de l'art antérieur, la fonction lumineuse de marqueur latéral était assurée en formant dans la parabole 14 et dans l'élément catadioptrique 19 des fenêtres pour un éclairement direct par le filament 12 du côté du véhicule, avec les inconvénients précités.Finally, it can be noted that the outer cheek of the reflecting part 14a and the retro-reflecting element 19 are in no way troublesome for the creation of the beam of the lateral marker function. Thus, the parabola 14a can retain a relatively closed shape, to the benefit of the intensity of the axial beam of the position light, and it is not necessary to modify or move the retro-reflecting element 19. In fact, these two organs of the fire are bypassed by the side beam. In this regard, it may be recalled that, in the blocks of flat profile lights of the prior art, the light function of lateral marker was ensured by forming in the parabola 14 and in the catadioptric element 19 windows for direct illumination by the filament 12 on the vehicle side, with the aforementioned drawbacks.

Sur la figure 2 est représentée une variante de réalisation de l'invention. Sur cette figure, les éléments identiques à ceux de la figure 1 sont désignés par les mêmes numéros de référence. La différence majeure entre cette forme de réalisation et celle de la figure 1 réside dans la forme de la partie latérale du réflecteur 14. Afin de donner à cette partie, indiquée en 14b', un encombrement latéral aussi faible que possible, elle est maintenant constituée par un ensemble de parties de paraboles homofocales étagées et concentriques, ayant approximativement pour foyer le filament 12 de la lampe. Le résultat obtenu reste sensiblement inchangé.In Figure 2 is shown an alternative embodiment of the invention. In this figure, the elements identical to those of Figure 1 are designated by the same reference numbers. The major difference between this embodiment and that of FIG. 1 resides in the shape of the lateral part of the reflector 14. In order to give this part, indicated at 14b ′, as little lateral dimensions as possible, it is now made up by a set of parts of homofocal parables stepped and concentric, having approximately for focus the filament 12 of the lamp. The result obtained remains essentially unchanged.

Bien entendu, la présente invention ne se limite pas aux modes de réalisation décrits, mais s'étend à toute variante conforme aux revendications jointes.Of course, the present invention is not limited to the embodiments described, but extends to any variant according to the appended claims.

En particulier, on peut prévoir tout aménagement annexe, tant au niveau du réflecteur 14 que des éléments réfracteurs de la glace de fermeture, pour obtenir une continuité d'éclairement appropriée entre le faisceau de feu de position et le faisceau de marqueur latéral.In particular, we can plan any development annex, both at the reflector 14 and at the refracting elements of the closing glass, to obtain an appropriate lighting continuity between the position light beam and the side marker beam.

En outre, l'invention s'applique d'une façon générale à tout type de feu de signalisation de véhicule, à l'arrière ou à l'avant de celui-ci, dans lequel une région de coin de la glace de fermeture est apte à diffuser vers le côté associé du véhicule un faisceau lumineux auxiliaire, obtenu à partir du filament du feu concerné, dont l'orientation est approximativement transversale à l'axe général dudit feu.In addition, the invention applies generally to any type of vehicle signaling light, at the rear or at the front thereof, in which a corner region of the closing window is capable of diffusing towards the associated side of the vehicle an auxiliary light beam, obtained from the filament of the lamp concerned, the orientation of which is approximately transverse to the general axis of said lamp.

En particulier, l'invention peut être mise en oeuvre dans des feux de position comme dans des feux clignotants.In particular, the invention can be implemented in position lights as in flashing lights.
