Description

Description Description
Titre de l'invention : Dispositif d'éclairage de véhicule automobile présentant un aspect sans glace Title of the invention: Motor vehicle lighting device exhibiting an ice-free appearance
[0001] L'invention concerne le domaine de l'éclairage automobile. Plus précisément, l'invention concerne un dispositif lumineux de véhicule automobile comportant un module lumineux et des dispositifs de réglage manuel et dynamique de ce module lumineux. The invention relates to the field of automotive lighting. More precisely, the invention relates to a lighting device for a motor vehicle comprising a light module and devices for manual and dynamic adjustment of this light module.
[0002] De façon classique, un dispositif lumineux de véhicule automobile comporte un dispositif de réglage de l'orientation du ou des faisceaux lumineux qu'il est susceptible d'émettre. Ce dispositif de réglage permet, d'une part, de régler manuellement l'orientation d'un faisceau lumineux émis par ce dispositif lumineux, par exemple à l'issue de la fabrication de ce dis positif ou lorsqu'il est nécessaire de procéder à une réparation ou un remplacement de ce dispositif. Ce réglage manuel fixe ainsi une orientation de référence de ce faisceau lumineux, à partir de laquelle on peut procéder à un réglage dynamique de l'orientation du faisceau lumineux. A cet effet, le dispositif de réglage permet, d'autre part, de déplacer à volonté, dynamiquement, l'orientation du faisceau lumineux, à partir de cette orientation de réfé rence. Il est ainsi possible de réaliser des fonctions d'éclairage dynamique des virages ou des adaptations dynamiques de la portée du faisceau lumineux, par exemple en fonction de la pente de la route. Conventionally, a motor vehicle lighting device comprises a device for adjusting the orientation of the light beam (s) that it is capable of emitting. This adjustment device makes it possible, on the one hand, to manually adjust the orientation of a light beam emitted by this light device, for example at the end of the manufacture of this positive device or when it is necessary to proceed to repair or replacement of this device. This manual adjustment thus fixes a reference orientation of this light beam, from which it is possible to proceed with a dynamic adjustment of the orientation of the light beam. To this end, the adjustment device makes it possible, on the other hand, to move the orientation of the light beam at will, dynamically, from this reference orientation. It is thus possible to perform dynamic lighting functions of bends or dynamic adaptations of the range of the light beam, for example as a function of the slope of the road.
[0003] Les dispositifs connus comportent généralement un boîtier, pourvu d'éléments de fixation du dispositif à la carrosserie du véhicule automobile, et fermé par une glace de fermeture s'inscrivant dans la continuité de la carrosserie du véhicule. Cette glace a notamment pour fonction de protéger les différents éléments agencés dans le boîtier, et notamment le dis positif de réglage, des intempéries, comme la pluie ou la neige, et des projections depuis la route, par exemple de gravillons. [0003] Known devices generally comprise a housing, provided with elements for fixing the device to the body of the motor vehicle, and closed by a closing glass forming part of the continuity of the body of the vehicle. The function of this glass is in particular to protect the various elements arranged in the housing, and in particular the adjustment device, from bad weather, such as rain or snow, and projections from the road, for example of gravel.
[0004] Toutefois, il existe un besoin de supprimer cette glace de fermeture, pour des besoins no tamment d'aspect esthétique. Dans ce contexte, le dispositif de réglage n'est plus protégé. Il est ainsi possible que des éléments comme des feuilles, des graviers viennent détériorer son fonctionnement, de sorte que la fonction de réglage dynamique de l'orientation du faisceau lumineux n'est plus assurée. Le même inconvénient peut être constaté lorsque de l'eau ou de la neige s'accumule dans le boîtier au niveau de ce dispositif de réglage ou encore au niveau d'un module lumineux, et se transforme ensuite, en cas de température négative, en glace qui vient bloquer les mouvements des parties de ce dispositif de réglage ou de ce module lumineux qui sont pourtant nécessaire au réglage de l'orientation du fais ceau lumineux émis par ce module lumineux. [0004] However, there is a need to do away with this closing glass, in particular for aesthetic purposes. In this context, the adjustment device is no longer protected. It is thus possible that elements such as leaves or gravel deteriorate its operation, so that the function of dynamic adjustment of the orientation of the light beam is no longer ensured. The same drawback can be observed when water or snow accumulates in the housing at the level of this adjustment device or even at the level of a light module, and then turns, in the event of negative temperature, into glass which blocks the movements of the parts of this adjustment device or of this light module which are nevertheless necessary for adjusting the orientation of the light beam emitted by this light module.
[0005] Il existe ainsi un besoin pour un dispositif lumineux de véhicule automobile, présentant un aspect « sans glace de fermeture » et dont la fonction de réglage dynamique de l'orienta tion d'un faisceau lumineux émis par ce dispositif puisse être mise en oeuvre, y compris lorsque le dispositif lumineux subit des conditions difficiles, notamment lorsque de la neige s'accumule dans ce dispositif. La présente invention vise à répondre à ce besoin.[0005] There is thus a need for a motor vehicle lighting device, having an aspect "without closing glass" and whose function of dynamic adjustment of the orientation of a light beam emitted by this device can be implemented. work, even when the lighting device is subjected to difficult conditions, in particular when snow accumulates in this device. The present invention aims to meet this need.
[0006] A ces fins, l'invention a pour objet un dispositif lumineux d'un véhicule automobile, com prenant un boîtier et des organes de fixation du boîtier à une carrosserie du véhicule auto mobile, le dispositif comportant une platine agencée dans le boîtier et supportant au moins un module lumineux, le dispositif lumineux comprenant un dispositif de réglage manuel de l'orientation du boîtier par rapport aux organes de fixation du véhicule automobile agencé à l'extérieur du boîtier et un dispositif de réglage dynamique de l'orientation de la platine par rapport au boîtier agencé à l'intérieur du boîtier. [0006] For these purposes, the invention relates to a lighting device for a motor vehicle, comprising a housing and members for fixing the housing to a body of the mobile vehicle, the device comprising a plate arranged in the housing and supporting at least one light module, the light device comprising a device for manual adjustment of the orientation of the housing relative to the fasteners of the motor vehicle arranged outside the housing and a device for dynamic adjustment of the orientation of the housing. the plate relative to the housing arranged inside the housing.
[0007] On comprend que l'invention se propose ainsi de dissocier les fonctions de réglage manuel et de réglage dynamique. La fonction de réglage manuel étant mise en oeuvre soit en sortie d'usine, soit au garage, il est ainsi possible de nettoyer le dispositif lumineux de sorte à pouvoir procéder au réglage manuel sans problème. L'intégration du dispositif de réglage dynamique dans le boîtier permet en revanche de protéger ce dispositif de réglage, de sorte à éviter que des éléments extérieurs, et notamment de la neige, vienne détériorer ou em pêcher son fonctionnement. Il est ainsi possible de se passer de la présence d'une glace de protection venant complètement obturer la cavité prévue dans la carrosserie destinée à recevoir le dispositif lumineux, de sorte à obtenir un dispositif lumineux d'aspect « sans glace de fermeture ». It is understood that the invention thus proposes to separate the functions of manual adjustment and of dynamic adjustment. The manual adjustment function being implemented either at the factory or in the garage, it is thus possible to clean the lighting device so that manual adjustment can be carried out without any problem. The integration of the dynamic adjustment device in the housing, on the other hand, makes it possible to protect this adjustment device, so as to prevent external elements, and in particular snow, from damaging or preventing its operation. It is thus possible to dispense with the presence of a protective glass completely closing off the cavity provided in the bodywork intended to receive the lighting device, so as to obtain a luminous device with a “non-closing glass” appearance.
[0008] Avantageusement, le boîtier est au moins partiellement, notamment totalement, fermé par une glace de fermeture. Le cas échéant, le dispositif de réglage dynamique est ainsi protégé par cette glace de fermeture. En outre, lorsque le dispositif lumineux est monté sur le véhi cule automobile, la glace de fermeture est agencée pour s'étendre dans la cavité prévue dans la carrosserie destinée à recevoir le dispositif lumineux, et non, comme dans les pro jecteurs connus, dans la continuité de cette carrosserie. De la sorte, le dispositif lumineux apparaît, du point de vue d'un observateur extérieur, comme étant dépourvu de glace de fermeture. La glace de fermeture est avantageusement formée d'une seule pièce réalisée en matériau transparent. Advantageously, the housing is at least partially, in particular completely, closed by a closing glass. If necessary, the dynamic adjustment device is thus protected by this closing glass. In addition, when the lighting device is mounted on the motor vehicle, the closing glass is arranged to extend into the cavity provided in the bodywork intended to receive the lighting device, and not, as in known headlamps, in the continuity of this bodywork. In this way, the lighting device appears, from the point of view of an outside observer, as being devoid of closing glass. The closing glass is advantageously formed from a single piece made of transparent material.
[0009] Avantageusement, le boîtier comporte une ouverture avant délimitée par un pourtour et la glace de fermeture est agencée pour au moins partiellement fermer cette ouverture. Par exemple, le boîtier comporte une gorge de collage formée sur le pourtour de l'ouverture avant, et la glace de fermeture comporte un rebord périphérique reçu et collé dans cette gorge de collage. Advantageously, the housing has a front opening delimited by a periphery and the closing glass is arranged to at least partially close this opening. For example, the housing has a gluing groove formed around the periphery of the front opening, and the closing glass has a peripheral rim received and glued in this gluing groove.
[0010] Dans un mode de réalisation de l'invention, la glace de fermeture est pourvue d'au moins un logement faisant saillie, notamment vers l'avant du dispositif lumineux, du reste de la glace et dans lequel s'étend au moins partiellement le module lumineux. Avantageusement, le logement présente une forme correspondant à celle du module lumineux et s'étend ainsi autour d'au moins une partie du module lumineux. Avantageusement, les dimensions du logement sont sensiblement supérieures à celles du module lumineux, de sorte à autoriser un déplacement horizontal et/ou vertical du module lumineux dans ce logement. Par exemple, le module lumineux comporte une source lumineuse et un élément optique de projection agencé pour projeter sur la route un faisceau lumineux émis par la source lumi neuse, et au moins l'élément optique de projection du module lumineux s'étend dans le logement. Le cas échéant, le ou les logements faisant saillie depuis une portion principale de la glace de fermeture, la portion principale s'étend en arrière de cet élément optique de projection. Il est en outre à relever que la dissociation des fonctions de réglage manuel et de réglage dynamique permet de limiter le jeu entre le module lumineux et les parois de ce logement au débattement du module lumineux nécessaire pour le réglage dynamique, sans avoir à tenir compte du débattement nécessaire au réglage manuel. Par exemple, ce débat tement, pour un réglage dynamique de l'orientation du faisceau lumineux susceptible d'être émis par le module lumineux de plus ou moins 3°, peut être compris entre plus ou moins 2 mm. Dès lors, il est possible d'agencer la paroi de ce logement au plus proche du module lumineux, renforçant ainsi l'aspect « sans glace de fermeture. In one embodiment of the invention, the closing glass is provided with at least one housing projecting, in particular towards the front of the lighting device, from the rest of the glass and in which extends at least partially the light module. Advantageously, the housing has a shape corresponding to that of the light module and thus extends around at least part of the light module. Advantageously, the dimensions of the housing are substantially greater than those of the light module, so as to allow horizontal and / or vertical movement of the light module in this housing. Through For example, the light module comprises a light source and a projection optical element arranged to project on the road a light beam emitted by the light source, and at least the projection optical element of the light module extends into the housing. Where appropriate, the housing or housings projecting from a main portion of the closing glass, the main portion extends behind this projection optical element. It should also be noted that the dissociation of the manual adjustment and dynamic adjustment functions makes it possible to limit the clearance between the light module and the walls of this housing to the clearance of the light module necessary for the dynamic adjustment, without having to take into account the travel required for manual adjustment. For example, this debate, for a dynamic adjustment of the orientation of the light beam capable of being emitted by the light module by plus or minus 3 °, may be between plus or minus 2 mm. Therefore, it is possible to arrange the wall of this housing as close as possible to the light module, thus reinforcing the aspect “without closing glass.
[0011] Avantageusement, le logement de la glace de fermeture comporte une portion avant, no tamment de forme concave par rapport au module lumineux, destinée à être traversée par un faisceau lumineux émis par le module lumineux. Si on le souhaite, le logement de la glace de fermeture peut comporter une portion, par exemple inférieure, faisant saillie vers l'avant du dispositif par rapport à la portion avant. Ces différentes caractéristiques permet tent notamment de renforcer l'aspect visuel « sans glace de fermeture » du dispositif lumi neux. Advantageously, the housing of the closing glass comprises a front portion, in particular of concave shape with respect to the light module, intended to be traversed by a light beam emitted by the light module. If desired, the housing of the closing glass may include a portion, for example lower, projecting towards the front of the device relative to the front portion. These different characteristics make it possible in particular to reinforce the visual aspect “without closing glass” of the light device.
[0012] De préférence, le dispositif lumineux comporte un enjoliveur opaque agencé devant la glace de fermeture et s'étendant autour du logement de la glace de fermeture et/ou s'éten dant contre la portion principale de la glace de fermeture. Dans un mode de réalisation de l'invention, les organes de fixation comprennent un exosquelette pourvu d'éléments de fixation de G exosquelette à la carrosserie du véhicule automobile, le boîtier étant monté sur G exosquelette au moyen du dispositif de réglage manuel. Avantageusement, les élé ments de fixation sont agencés pour interdire tout déplacement de l'exosquelette par rap port à la carrosserie. Si on le souhaite, les organes de fixation comprennent des pattes de fixation à la carrosserie, chacune des pattes comprenant une zone de fragilité, par exemple de moindre épaisseur par rapport au reste de la patte, destinée à permettre une rupture de la patte lors d'un impact d'un obstacle avec le véhicule automobile, par exemple un pié ton, entraînant un décrochement du dispositif lumineux de la carrosserie. Si on le souhaite, l'exosquelette peut supporter d'autres éléments du dispositif lumineux, et notamment des modules de signalisation ou des enjoliveurs ou des masques du dispositif lumineux. Avan tageusement, le dispositif lumineux est dépourvu de glace de fermeture destinée à fermer l'exosquelette. [0012] Preferably, the luminous device comprises an opaque cover arranged in front of the closing glass and extending around the housing of the closing glass and / or extending against the main portion of the closing glass. In one embodiment of the invention, the fixing members comprise an exoskeleton provided with elements for fixing the exoskeleton to the body of the motor vehicle, the housing being mounted on the exoskeleton by means of the manual adjustment device. Advantageously, the fixing elements are arranged to prevent any displacement of the exoskeleton with respect to the bodywork. If desired, the fasteners comprise lugs for fixing to the body, each of the lugs comprising a zone of weakness, for example of less thickness compared to the rest of the lug, intended to allow the lug to break when 'an impact of an obstacle with the motor vehicle, for example a pedestrian, causing the lighting device to detach from the bodywork. If desired, the exoskeleton can support other elements of the lighting device, and in particular signaling modules or hubcaps or masks of the lighting device. Advantageously, the light device is devoid of closing glass intended to close the exoskeleton.
[0013] Selon un exemple de réalisation de l'invention, le dispositif de réglage manuel comporte trois organes de liaison de type rotule, entre les organes de fixation et le boîtier. Le cas échéant, les organes de liaison comportent un point de liaison, dit fixe, autour duquel le boîtier peut pivoter, un organe de réglage manuel vertical apte à appliquer un effort sur le boîtier au niveau de cet organe et un organe de réglage manuel horizontal apte à appliquer un effort sur le boîtier au niveau de cet organe, le point fixe et l'organe de réglage manuel vertical définissant un axe vertical autour duquel le boîtier peut pivoter et le point fixe et l'organe de réglage manuel horizontal définissant un axe horizontal autour duquel le boîtier peut pivoter. [0013] According to an exemplary embodiment of the invention, the manual adjustment device comprises three connecting members of the ball joint type, between the fixing members and the housing. Where appropriate, the connecting members include a so-called fixed connection point, around which the housing can pivot, a vertical manual adjustment member adapted to apply a force to the housing at this member and a horizontal manual adjustment member capable of applying a force to the housing at this member, the fixed point and the vertical manual adjustment member defining a vertical axis around which the housing can pivot and the fixed point and the horizontal manual adjustment member defining a horizontal axis around which the housing can pivot.
[0014] Avantageusement, le point fixe comporte une vis à tête sensiblement sphérique montée fixe sur l'exosquelette, la tête étant logée dans un logement sensiblement sphérique d'une capsule fixée au boîtier. Avantageusement, l'un ou chacun des organes de réglage manuel vertical et horizontal comprend une vis montée mobile en translation, notamment horizon tale, sur l'exosquelette et comportant une tête encliquetée dans une capsule fixée au boîtier. Par exemple, la vis montée mobile en translation sur l'exosquelette est montée dans un logement de l'exosquelette comportant un filetage interne coopérant avec un filetage ex terne de la vis. Si on le souhaite, l'un ou chacun des organes de réglage manuel vertical et horizontal peut comprendre une vis de réglage s'étendant verticalement par rapport à l'exosquelette et engrenée sur un pignon de renvoi, lui-même engrenée sur la vis montée mobile en translation horizontal Advantageously, the fixed point comprises a screw with a substantially spherical head fixedly mounted on the exoskeleton, the head being housed in a substantially spherical housing of a capsule fixed to the housing. Advantageously, one or each of the vertical and horizontal manual adjustment members comprises a screw mounted movable in translation, in particular horizontal, on the exoskeleton and comprising a head snapped into a capsule fixed to the housing. For example, the screw mounted to move in translation on the exoskeleton is mounted in a housing of the exoskeleton comprising an internal thread cooperating with an external thread of the screw. If desired, one or each of the vertical and horizontal manual adjusters may include an adjustment screw extending vertically with respect to the exoskeleton and meshed with an idler gear, itself meshed with the mounted screw. mobile in horizontal translation
[0015] Dans un mode de réalisation de l'invention, la platine est montée sur le boîtier au moyen du dispositif de réglage dynamique. In one embodiment of the invention, the plate is mounted on the housing by means of the dynamic adjustment device.
[0016] Avantageusement, le dispositif de réglage dynamique comporte trois organes de liaison de type rotule, entre la platine et le boîtier, dont un point de liaison, dit fixe, autour duquel la platine peut pivoter et au moins un organe de réglage dynamique vertical ou horizon tal comportant un actionneur relié, directement ou indirectement, à la platine et apte à appliquer un effort sur la platine au niveau de cet organe, le point fixe définissant avec l'un des ou les deux autres organes de liaison un axe vertical et/ou un axe horizontal autour desquels la platine peut pivoter. Le troisième organe de liaison peut être également un point fixe, ou être un organe de réglage manuel ou dynamique horizontal ou vertical. Le cas échéant, le dispositif de réglage dynamique peut comporter une unité de contrôle agencée pour contrôler l'actionneur. Advantageously, the dynamic adjustment device comprises three ball joint type connecting members, between the plate and the housing, including a so-called fixed connection point, around which the plate can pivot and at least one vertical dynamic adjustment member or horizon tal comprising an actuator connected, directly or indirectly, to the plate and capable of applying a force to the plate at the level of this member, the fixed point defining with one or both of the other connecting members a vertical axis and / or a horizontal axis around which the plate can pivot. The third connecting member can also be a fixed point, or be a manual or dynamic horizontal or vertical adjustment member. Where appropriate, the dynamic adjustment device may include a control unit arranged to control the actuator.
[0017] Par exemple, l'actionneur peut être un moteur électrique à courant continu ou un moteur électrique pas à pas. Par exemple toujours, l'unité de contrôle peut être agencée pour re cevoir des instructions depuis un calculateur du véhicule automobile, par exemple une ins truction de modification de l'orientation verticale ou horizontale du faisceau lumineux émis par le module lumineux déterminée en fonction d'une pente ou d'une courbure de la route et pour contrôler l'actionneur de sorte à entraîner une rotation de la platine autour de l'axe vertical et/ou horizontal conformément à ces instructions reçues [0017] For example, the actuator can be a direct current electric motor or a stepping electric motor. For example always, the control unit can be arranged to receive instructions from a computer of the motor vehicle, for example an instruction for modifying the vertical or horizontal orientation of the light beam emitted by the light module determined as a function of '' a slope or curvature of the road and to control the actuator so as to cause a rotation of the plate around the vertical and / or horizontal axis in accordance with these instructions received
[0018] Selon un exemple de réalisation, le module lumineux est un module lumineux agencé pour émettre un faisceau d'éclairage de la route. Par exemple, il peut s'agir d'un module lumi neux agencé pour émettre un faisceau d'éclairage de type croisement réglementaire, de type route réglementaire ou encore de type segmenté ou pixélisé. Si on le souhaite, le dis positif lumineux peut comporter une pluralité de modules lumineux supportés par la pla tine. Le cas échéant, la platine peut comporter une pluralité de sous-platines supportant chacune l'un des modules lumineux. [0018] According to an exemplary embodiment, the light module is a light module arranged to emit a road lighting beam. For example, it may be a light module designed to emit a lighting beam of the regulatory crossing type, of regulatory road type or segmented or pixelated type. If desired, the luminous device can comprise a plurality of luminous modules supported by the plate. Where appropriate, the plate may include a plurality of sub-plates each supporting one of the light modules.
[0019] La présente invention est maintenant décrite à l'aide d'exemples uniquement illustratifs et nullement limitatifs de la portée de l'invention, et à partir des illustrations jointes, dans lesquelles : The present invention is now described with the aid of examples which are only illustrative and in no way limitative of the scope of the invention, and from the accompanying illustrations, in which:

[0025] Dans la description qui suit, les éléments identiques, par structure ou par fonction, appa raissant sur différentes figures conservent, sauf précision contraire, les mêmes références. En outre, les termes « avant », « arrière », « haut » et « bas » doivent être interprétés dans le contexte de l'orientation du dispositif d'éclairage tel qu'il a été représenté, correspon dant à une utilisation normale du dispositif d'éclairage, comme par exemple lorsqu'il est monté dans un véhicule automobile. In the following description, the identical elements, by structure or by function, appearing in different figures retain, unless otherwise specified, the same references. In addition, the terms "front", "rear", "top" and "bottom" should be interpreted in the context of the orientation of the lighting device as shown, corresponding to normal use of the light. lighting device, such as for example when it is mounted in a motor vehicle.
[0026] On a représenté en [Fig. 1] une vue en face avant, schématique et partielle, d'un dispositif lumineux 1 d'un véhicule automobile. La [Fig. 2] représente un éclaté de ce dispositif lumi neux 1 tandis que la [Fig. 3] représente une vue en coupe, par un plan vertical, de ce dispo sitif lumineux 1. There is shown in [Fig. 1] a front view, schematic and partial, of a lighting device 1 of a motor vehicle. The [Fig. 2] shows an exploded view of this light device 1 while [Fig. 3] shows a sectional view, through a vertical plane, of this lighting device 1.
[0027] Le dispositif lumineux 1 comporte un premier module lumineux 21, agencé pour émettre un faisceau d'éclairage de type croisement réglementaire, et un deuxième module lumi neux 22, agencé pour émettre un faisceau d'éclairage de type route pixélisé. Dans l'exemple décrit, sans que cela soit limitatif, le premier module 21 comporte une source lumineuse 21a, un réflecteur 21b et une lentille de projection 21c, ces éléments étant supportés par une même pièce 21d formant un dissipateur de chaleur. Le premier module 21 est ainsi agencé pour que la lumière émise par la source lumineuse 21a soit réfléchie par le réflec teur 21b et ensuite projetée sur la route par la lentille de projection 21c pour former un faisceau lumineux présentant une coupure supérieure de type croisement réglementaire. Le deuxième module lumineux 22 comporte une pluralité de sources lumineuses 22a, une pluralité de microlentilles 22b chacune associée à l'une des sources lumineuses 22a et un dispositif optique de projection 22c comprenant deux lentilles, ces éléments étant montés sur un support 22d. Le deuxième module 22 est ainsi agencé pour que la lumière émise par chacune des sources lumineuses soit projetée sur la route, après avoir traversée la micro lentille associée 22b et le dispositif optique 22c, en formant un faisceau lumineux élémen taire, l'ensemble des faisceaux lumineux élémentaires issus de toutes les sources lumi neuses 22a formant ainsi un faisceau lumineux de type rouge segmenté. Chacune des sources lumineuses 22a est contrôlée sélectivement par une unité de contrôle (non repré sentée) de sorte à allumer, éteindre le faisceau lumineux élémentaire émis par cette source ou à en modifier l'intensité lumineuse. The light device 1 comprises a first light module 21, arranged to emit a lighting beam of regulatory crossing type, and a second light module 22, arranged to emit a pixelated road type lighting beam. In the example described, without this being limiting, the first module 21 comprises a light source 21a, a reflector 21b and a projection lens 21c, these elements being supported by the same part 21d forming a heat sink. The first module 21 is thus arranged so that the light emitted by the light source 21a is reflected by the reflector 21b and then projected onto the road by the projection lens 21c to form a light beam having an upper cutoff of the regulatory crossing type. The second light module 22 comprises a plurality of light sources 22a, a plurality of microlenses 22b each associated with one of the light sources 22a and an optical projection device 22c comprising two lenses, these elements being mounted on a 22d support. The second module 22 is thus arranged so that the light emitted by each of the light sources is projected onto the road, after having passed through the associated micro lens 22b and the optical device 22c, forming an elementary light beam, all of the beams elementary light coming from all the light sources 22a thus forming a light beam of the segmented red type. Each of the light sources 22a is selectively controlled by a control unit (not shown) so as to turn on and off the elementary light beam emitted by this source or to modify its light intensity.
[0028] Chaque module lumineux 21 et 22 est monté sur une sous-platine 31, respectivement 32, les sous-platines 31, 32 étant solidaires et formant une platine 3. Le dispositif lumineux 1 comporte un boîtier 4 définissant un volume intérieur dans lequel sont agencés la platine 3 et les modules lumineux 21 et 22. On a représenté en [Fig. 4] une vue partielle, en face avant, du dispositif lumineux 1 montrant un exemple de fixation de la platine 3 sur le boîtier 4. Dans cet exemple, la platine 3 est montée sur le boîtier 4 au moyen d'un dispositif de réglage dynamique 5 permettant d'orienter dynamiquement la platine 3 par rapport au boîtier 4. Each light module 21 and 22 is mounted on a sub-plate 31, respectively 32, the sub-plates 31, 32 being integral and forming a plate 3. The lighting device 1 comprises a housing 4 defining an internal volume in which are arranged the plate 3 and the light modules 21 and 22. There is shown in [Fig. 4] a partial view, on the front face, of the lighting device 1 showing an example of fixing the plate 3 on the housing 4. In this example, the plate 3 is mounted on the housing 4 by means of a dynamic adjustment device 5 allowing the plate 3 to be dynamically oriented relative to the housing 4.
[0029] Le dispositif de réglage dynamique 5 comporte un premier organe de liaison 51, de type rotule, entre la sous-platine 32 et le boîtier 4, dit point fixe. Cet organe 51 comporte une vis à tête sensiblement sphérique 51a montée fixe sur le boîtier 4, la tête étant logée dans un logement sensiblement sphérique d'une capsule 51b fixée à la sous-platine 32. The dynamic adjustment device 5 comprises a first connecting member 51, of the ball joint type, between the sub-plate 32 and the housing 4, said fixed point. This member 51 comprises a screw with a substantially spherical head 51a fixedly mounted on the housing 4, the head being housed in a substantially spherical housing of a capsule 51b fixed to the sub-plate 32.
[0030] Le dispositif de réglage dynamique 5 comporte un deuxième organe de liaison 52 de type rotule, comportant un actionneur 52a fixé au boîtier 4 et relié à la sous-platine 32 par une vis 52b encliquetée, par une liaison rotule, dans une capsule 52c fixée à cette sous-platine 32. La vis 52b est susceptible d'être entraînée en translation horizontale par l'actionneur 52a, de sorte à venir appliquer un effort sur la sous-platine 32 au niveau de la capsule 52c. Dans l'exemple décrit, le dispositif de réglage dynamique 5 comporte un troisième organe de liaison 53, de type rotule, entre la sous-platine 31 et le boîtier 4, semblable au point fixe 51, c'est-à-dire composé d'une vis 53a montée sur le boîtier 4 et dont la tête est logée dans une capsule 53b montée sur la sous-platine 31 en étant agencé sensiblement au-dessus de ce point fixe 51. The dynamic adjustment device 5 comprises a second connecting member 52 of the ball-joint type, comprising an actuator 52a fixed to the housing 4 and connected to the sub-plate 32 by a snap-in screw 52b, by a ball-joint connection, in a capsule 52c fixed to this sub-plate 32. The screw 52b is capable of being driven in horizontal translation by the actuator 52a, so as to apply a force to the sub-plate 32 at the level of the capsule 52c. In the example described, the dynamic adjustment device 5 comprises a third connecting member 53, of the ball joint type, between the sub-plate 31 and the housing 4, similar to the fixed point 51, that is to say composed of 'a screw 53a mounted on the housing 4 and the head of which is housed in a capsule 53b mounted on the sub-plate 31 while being arranged substantially above this fixed point 51.
[0031] Les points fixes 51 et 53 définissent ainsi un axe vertical VI autour duquel la platine peut pivoter, notamment lorsque le deuxième organe de liaison 52 vient exercer un effort pous sant ou tirant sur la platine 3 au niveau de la capsule 52c. Le dispositif de réglage dynamique 5 comporte ainsi une unité de contrôle (non représenté) agencée pour recevoir, depuis un calculateur du véhicule automobile, des instructions de modification de l'orientation hori zontale des faisceaux lumineux émis par les modules lumineux 21 et 22, par exemple dé terminées d'une courbure de la route et pour contrôler l'actionneur 52a du deuxième or gane de liaison 52 de sorte à entraîner une rotation de la platine autour de l'axe vertical VI conformément à ces instructions reçues. Le dispositif de réglage dynamique 5 permet ainsi de modifier dynamiquement l'orientation horizontale des faisceaux lumineux émis par les premier et deuxième modules lumineux 21 et 22, de sorte par exemple à permettre la réa lisation d'une fonction d'éclairage dynamique des virages. The fixed points 51 and 53 thus define a vertical axis VI around which the plate can pivot, in particular when the second connecting member 52 exerts a force pushing or pulling on the plate 3 at the level of the capsule 52c. The dynamic adjustment device 5 thus comprises a control unit (not shown) arranged to receive, from a computer of the motor vehicle, instructions for modifying the horizontal orientation of the light beams emitted by the light modules 21 and 22, by example determined by a curvature of the road and to control the actuator 52a of the second connecting member 52 so as to cause a rotation of the plate around the vertical axis VI in accordance with these instructions received. The dynamic adjustment device 5 thus allows dynamically modifying the horizontal orientation of the light beams emitted by the first and second light modules 21 and 22, so as for example to allow the realization of a dynamic lighting function of bends.
[0032] Dans l'exemple décrit, le boîtier 4 comporte une ouverture avant délimitée par un pourtour 41 sur lequel est formée une gorge de collage 42. L'ouverture du boîtier 4 est fermée par une glace de fermeture 6 dont un rebord périphérique 61 est reçu et collé dans cette gorge de collage 42. La glace de fermeture 6 est formée d'une seule pièce réalisée en matériau transparent. In the example described, the housing 4 has a front opening delimited by a periphery 41 on which is formed a bonding groove 42. The opening of the housing 4 is closed by a closing glass 6 including a peripheral rim 61 is received and glued in this bonding groove 42. The closing glass 6 is formed in one piece made of transparent material.
[0033] La glace de fermeture 6 est pourvue d'une portion principale 62 s'étendant à partir du re bord périphérique et depuis laquelle font saillie, vers l'avant du dispositif lumineux, un pre mier logement 63 et d'un deuxième logement 64. Une portion du premier module lumineux 21, et notamment la lentille de projection 21c, s'étend dans le premier logement 63. De même, une portion du deuxième module lumineux 22, et notamment le dispositif optique de projection 22c, s'étend dans le deuxième logement 64. On constatera au vu de la [Fig. 3] que chaque logement 63, 64 s'étend ainsi autour du module lumineux 21, 22 qu'il loge, leurs dimensions étant telles qu'elles autorisent un déplacement horizontal des modules lumineux 21, 22, par exemple entraîné par le dispositif de réglage dynamique 5, dans leurs logements. On notera également que la portion principale 62 s'étend en arrière des élé ments optiques de projection 21c et 22c. The closing glass 6 is provided with a main portion 62 extending from the re peripheral edge and from which protrude, towards the front of the lighting device, a first housing 63 and a second housing 64. A portion of the first light module 21, and in particular the projection lens 21c, extends into the first housing 63. Likewise, a portion of the second light module 22, and in particular the optical projection device 22c, extends in the second housing 64. It will be seen in the light of [FIG. 3] that each housing 63, 64 thus extends around the light module 21, 22 which it houses, their dimensions being such that they allow horizontal displacement of the light modules 21, 22, for example driven by the adjustment device. dynamic 5, in their homes. It will also be noted that the main portion 62 extends behind the projection optical elements 21c and 22c.
[0034] Chaque logement 63, 64 comporte une portion avant concave 63a, respectivement 64a, destinée à être traversée par un faisceau lumineux émis par le module lumineux 21, 22 agencé dans ce logement, ainsi qu'une une portion inférieure 63b, respectivement 64b, faisant saillie vers l'avant du dispositif 1 par rapport à la portion avant. Each housing 63, 64 comprises a concave front portion 63a, respectively 64a, intended to be traversed by a light beam emitted by the light module 21, 22 arranged in this housing, as well as a lower portion 63b, respectively 64b , protruding towards the front of the device 1 with respect to the front portion.
[0035] Comme on le constate, le dispositif de réglage dynamique 5 est ainsi protégé par cette glace de fermeture 6. En outre, lorsque le dispositif lumineux 1 est monté sur le véhicule auto mobile, la glace de fermeture 6 s'étend dans la cavité prévue dans la carrosserie C (repré sentée en hachurée) recevant le dispositif lumineux 1. Du fait des dimensions et de la forme de la glace 6 et du boîtier 4, de l'absence de vitre s'étendant depuis la paroi supérieure vers la paroi inférieure de la carrosserie C, de la présence des logements 63, 64 sur la glace 6, en particulier de la forme des portions avant concave 63a et 64a, venant mimer une lentille optique et des portions inférieures 63b et 63c venant accentuer un effet de profondeur, le dispositif lumineux apparaît 1, du point de vue d'un observateur extérieur, comme étant dépourvu de glace de fermeture. As can be seen, the dynamic adjustment device 5 is thus protected by this closing glass 6. In addition, when the lighting device 1 is mounted on the motor vehicle, the closing glass 6 extends into the cavity provided in the body C (represented in hatched lines) receiving the lighting device 1. Due to the dimensions and shape of the glass 6 and of the housing 4, the absence of glass extending from the upper wall towards the lower wall of the body C, the presence of the housings 63, 64 on the glass 6, in particular the shape of the concave front portions 63a and 64a, mimicking an optical lens and the lower portions 63b and 63c accentuating an effect of depth, the luminous device appears 1, from the point of view of an outside observer, as being devoid of closing glass.
[0036] Le dispositif 1 comporte en outre un exosquelette 7 permettant de monter le boîtier 4 sur la carrosserie C du véhicule. On a représenté en [Fig. 5] une vue partielle, en face arrière, du dispositif lumineux 1 montrant cet exosquelette 7 sur lequel est monté le boîtier 4. L'exosquelette 7 est pourvu de pattes de fixation 71 permettant de le fixer à la carrosserie C, sans qu'il soit possible, dans l'exemple décrit, de le déplacer par rapport à cette carros serie C. [00B7] Le dispositif 1 comporte un dispositif de réglage manuel 8 à l'aide duquel le boîtier 4 est monté sur l'exosquelette 7. Ce dispositif de réglage manuel 8 comporte un premier organe de liaison 81, de type rotule, entre l'exosquelette 7 et le boîtier 4, dit point fixe. Cet organe 81 comporte une vis à tête sensiblement sphérique 81a montée fixe sur l'exosquelette 7, la tête étant logée dans un logement sensiblement sphérique d'une capsule 81b fixée au boî tier 4. The device 1 further comprises an exoskeleton 7 for mounting the housing 4 on the body C of the vehicle. There is shown in [FIG. 5] a partial view, on the rear face, of the lighting device 1 showing this exoskeleton 7 on which the box 4 is mounted. The exoskeleton 7 is provided with fixing lugs 71 allowing it to be fixed to the body C, without it being is possible, in the example described, to move it relative to this C series body. The device 1 comprises a manual adjustment device 8 with the aid of which the housing 4 is mounted on the exoskeleton 7. This manual adjustment device 8 comprises a first connecting member 81, of the ball type, between the exoskeleton 7 and case 4, called a fixed point. This member 81 comprises a screw with a substantially spherical head 81a fixedly mounted on the exoskeleton 7, the head being housed in a substantially spherical housing of a capsule 81b fixed to the housing 4.
[0038] Le dispositif de réglage manuel 8 comporte en outre deux organes de réglage manuel 82 et 83. L'organe de réglage 82 est un organe de réglage manuel horizontal apte à appliquer un effort sur le boîtier au niveau de cet organe. Il comprend une vis 82a montée mobile, en translation horizontale, sur l'exosquelette 7 et pourvue d'une tête encliquetée, par une liai son rotule, dans une capsule 82b fixée au boîtier. Par exemple, la vis 82a est montée dans un logement de l'exosquelette comportant un filetage interne coopérant avec un filetage externe de la vis. La vis 82a est accessible depuis l'extérieur du boîtier 4 et de l'exosquelette 7, au niveau de la face arrière de cet exosquelette. Lorsqu'un opérateur manoeuvre la vis 82a, elle est entraînée en translation et vient exercer un effort sur le boîtier 4 au niveau de la capsule 82b. The manual adjustment device 8 further comprises two manual adjustment members 82 and 83. The adjustment member 82 is a horizontal manual adjustment member capable of applying a force to the housing at the level of this member. It comprises a screw 82a movably mounted, in horizontal translation, on the exoskeleton 7 and provided with a snap-fastened head, by a link to its ball joint, in a capsule 82b fixed to the housing. For example, the screw 82a is mounted in a housing of the exoskeleton comprising an internal thread cooperating with an external thread of the screw. The screw 82a is accessible from the outside of the housing 4 and of the exoskeleton 7, at the rear face of this exoskeleton. When an operator operates the screw 82a, it is driven in translation and exerts a force on the housing 4 at the level of the capsule 82b.
[0039] L'organe de réglage 83 est un organe de réglage manuel vertical apte à appliquer un effort sur le boîtier au niveau de cet organe. Il comprend un élément de réglage 83a, comprenant dans l'exemple décrit une vis de réglage montée verticalement dans l'exosquelette, engre nant un pignon de renvoi. Le pignon de renvoi est lui-même engrenée sur une vis montée mobile, en translation horizontale, sur l'exosquelette 7 et pourvue d'un une tête enclique tée, par une liaison rotule, dans une capsule 83b fixée au boîtier. L'élément 83a est acces sible depuis l'extérieur du boîtier 4 et de l'exosquelette 7, au niveau de la face supérieure de cet exosquelette. Lorsqu'un opérateur manoeuvre cet élément 83a, il vient entraîner la vis en translation horizontale et vient exercer un effort sur le boîtier 4 au niveau de la cap sule 83b. The adjustment member 83 is a vertical manual adjustment member capable of applying a force to the housing at the level of this member. It comprises an adjustment element 83a, comprising in the example described an adjustment screw mounted vertically in the exoskeleton, generating a return pinion. The return pinion is itself meshed on a screw mounted to move, in horizontal translation, on the exoskeleton 7 and provided with a snap-in head, via a ball joint, in a capsule 83b fixed to the housing. The element 83a is accessible from the outside of the housing 4 and of the exoskeleton 7, at the level of the upper face of this exoskeleton. When an operator operates this element 83a, he drives the screw in horizontal translation and exerts a force on the housing 4 at the level of the cap 83b.
[0040] , On comprend que le point fixe 81 et l'organe de réglage manuel horizontal 82 définissant un axe horizontal H1 autour duquel le boîtier 4 peut pivoter, notamment lorsque l'opéra teur manoeuvre l'organe de réglage vertical 83 et que le point fixe 81 et l'organe de réglage manuel vertical 83 définissant un axe vertical V2 autour duquel le boîtier 4 peut pivoter, notamment lorsque l'opérateur manoeuvre l'organe de réglage horizontal 82. It is understood that the fixed point 81 and the horizontal manual adjustment member 82 defining a horizontal axis H1 around which the housing 4 can pivot, in particular when the operator operates the vertical adjustment member 83 and that the fixed point 81 and the vertical manual adjustment member 83 defining a vertical axis V2 around which the housing 4 can pivot, in particular when the operator operates the horizontal adjustment member 82.
[0041] La description qui précède explique clairement comment l'invention permet d'atteindre les objectifs qu'elle s'est fixée, et notamment en proposant dissocier les fonctions de réglage manuel et de réglage dynamique dans un dispositif lumineux. Il est ainsi possible d'intégrer un dispositif de réglage dynamique dans un boîtier logeant le module lumineux à régler, ce qui permet de protéger ce dispositif de réglage des éléments extérieurs, et notamment de la neige. Il est ainsi possible de se passer de la présence d'une glace de protection venant complètement obturer la cavité prévue dans la carrosserie destinée à recevoir le dispositif lumineux, de sorte à obtenir un dispositif lumineux d'aspect « sans glace de fermeture ». [0042] En tout état de cause, l'invention ne saurait se limiter aux modes de réalisation spécifique ment décrits dans ce document, et s'étend en particulier à tous moyens équivalents et à toute combinaison techniquement opérante de ces moyens. En particulier, on pourra envi sager d'autres types de module lumineux que celui décrit, et en particulier des modules lumineux employant d'autres agencements optiques que ceux décrits. On pourrait adapter l'invention pour un unique module lumineux prévu dans le boîtier ou encore pour plus de deux modules lumineux prévus dans le boîtier. On pourra prévoir de fixer d'autres éléments du dispositif lumineux à l'exosquelette, et notamment d'autres modules lumineux, en par ticulier des modules de signalisation lumineuse, ou encore des enjoliveurs ou des masques destinés à cacher des parties non esthétiques du dispositif lumineux. The above description clearly explains how the invention makes it possible to achieve the objectives that it has set itself, and in particular by proposing to separate the functions of manual adjustment and of dynamic adjustment in a lighting device. It is thus possible to integrate a dynamic adjustment device in a housing housing the light module to be adjusted, which makes it possible to protect this adjustment device from external elements, and in particular from snow. It is thus possible to dispense with the presence of a protective glass completely closing off the cavity provided in the bodywork intended to receive the lighting device, so as to obtain a luminous device with a “non-closing glass” appearance. In any event, the invention cannot be limited to the embodiments specifically described in this document, and extends in particular to all equivalent means and to any technically operative combination of these means. In particular, it is possible to envision other types of light module than that described, and in particular light modules employing other optical arrangements than those described. The invention could be adapted for a single light module provided in the housing or even for more than two light modules provided in the housing. Provision may be made to attach other elements of the light device to the exoskeleton, and in particular other light modules, in particular light signaling modules, or even hubcaps or masks intended to hide non-aesthetic parts of the device. luminous.
