Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention concerne un dispositif d'éclairage et/ou de signalisation pour véhicule automobile.The present invention relates to a lighting and / or signaling device for a motor vehicle.

Elle trouve une application particulière mais non limitative dans les dispositifs d'éclairage, tels que des projecteurs avant de véhicule automobile.It finds a particular but non-limiting application in lighting devices, such as front projectors of a motor vehicle.

ARRIÈRE-PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Un dispositif d'éclairage et/ou de signalisation pour véhicule automobile, tel qu'un projecteur, comprend de manière connue de l'homme du métier :

  • un boîtier ;
  • une glace adaptée pour fermer le boîtier ;
  • au moins un module lumineux logé à l'intérieur dudit boîtier comprenant :
    • au moins une surface optique ;
    • au moins une source lumineuse coopérant avec ladite surface optique pour former un faisceau lumineux ;
    • un dissipateur de chaleur comportant une pluralité d'ailettes ;
  • ;
  • un générateur d'un flux d'air adapté pour générer un flux d'air vers le dissipateur de chaleur, ledit flux d'air traversant les ailettes du dissipateur de chaleur ; et
  • une platine support du module lumineux.
A lighting and / or signaling device for a motor vehicle, such as a projector, comprises, in a manner known to those skilled in the art:
  • a housing ;
  • a mirror adapted to close the case;
  • at least one light module housed inside said housing comprising:
    • at least one optical surface;
    • at least one light source cooperating with said optical surface to form a light beam;
    • a heat sink having a plurality of fins;
  • ;
  • an airflow generator adapted to generate an airflow to the heat sink, said airflow passing through the fins of the heat sink; and
  • a support plate of the light module.

De manière connue également, un conduit de circulation d'air rigide est placé entre le générateur de flux d'air et la glace du boîtier. Ce conduit amène de l'air chaud ayant traversé les ailettes du dissipateur de chaleur vers une zone de la glace, dite zone froide, susceptible de donner lieu à des phénomènes de condensation visible lorsqu'une source lumineuse est allumée.In a manner also known, a rigid air flow duct is placed between the air flow generator and the housing ice. This leads brings the hot air having passed through the fins of the heat sink to an area of the ice, called cold zone, likely to give rise to visible condensation phenomena when a light source is turned on.

Un inconvénient de cet état de la technique est qu'il est nécessaire de prévoir un conduit de circulation d'air dédié pour la circulation de l'air entre le générateur de flux d'air et la glace du boîtier. Cela engendre l'utilisation d'une ou plusieurs pièces supplémentaires dans le boîtier entraînant des coûts plus importants de fabrication ainsi qu'un plus grand encombrement.A disadvantage of this state of the art is that it is necessary to provide a dedicated air flow duct for the flow of air between the air flow generator and the housing ice. This results in the use of one or more additional parts in the package resulting in higher manufacturing costs as well as greater bulk.

Dans ce contexte, la présente invention vise à résoudre les inconvénients précédemment mentionnés.In this context, the present invention aims to solve the aforementioned drawbacks.

DESCRIPTION GENERALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

A cette fin l'invention propose un dispositif d'éclairage et/ou de signalisation pour véhicule automobile, ledit dispositif d'éclairage et/ou de signalisation comprenant :

  • un boîtier ;
  • une glace adaptée pour fermer le boîtier ;
  • au moins un module lumineux logé à l'intérieur dudit boîtier comprenant :
    • au moins une surface optique ;
    • au moins une source lumineuse coopérant avec ladite surface optique pour former un faisceau lumineux ;
    • un dissipateur de chaleur comportant une pluralité d'ailettes ;
  • un générateur d'un flux d'air adapté pour générer un flux d'air vers le dissipateur de chaleur, ledit flux d'air traversant les ailettes du dissipateur de chaleur ; et
  • une platine support du module lumineux comportant une partie avant orientée vers la glace et comprenant une pluralité d'interstices adaptés pour diriger le flux d'air provenant du dissipateur de chaleur vers la glace.
To this end, the invention proposes a lighting and / or signaling device for a motor vehicle, said lighting and / or signaling device comprising:

La platine support du module lumineux est une pièce préexistante dans le boîtier, il n'est donc pas nécessaire d'avoir recours à un élément supplémentaire comme dans l'état de la technique antérieur pour assurer la circulation de l'air.

By motor vehicle, we mean any type of motorized vehicle.
In a nonlimiting example taken in the following description, the lighting and / or signaling device 10 is a front projector of a motor vehicle.

Comme illustré sur la vue en coupe de la figure 1 et sur la vue en perspective de la figure 4, le dispositif d'éclairage et/ou de signalisation 10 comprend :

  • un boîtier 1 ;
  • une glace 3 adaptée pour fermer le boîtier 1 ;

  • une platine support 19 du module lumineux 5comportant une partie avant 20 orientée vers la glace 3 et comprenant une pluralité d'interstices 21 adaptés pour diriger le flux d'air 17 provenant du dissipateur de chaleur 11 vers la glace 3.
As shown in the sectional view of the figure 1 and on the perspective view of the figure 4 the lighting and / or signaling device 10 comprises:
  • a housing 1;
  • an ice cream 3 adapted to close the housing 1;
  • at least one light module 5 housed inside said housing 1 connected to a heat sink 11 having a plurality of fins 13;

  • a support plate 19 of the light module 5comportant a front portion 20 oriented towards the ice 3 and comprising a plurality of interstices 21 adapted to direct the flow of air 17 from the heat sink 11 to the ice 3.

Dans un mode de réalisation non limitatif, le dispositif d'éclairage et/ou de signalisation 10 comprend en outre un élément structurel complémentaire 23, appelé exosquelette. Ledit exosquelette est rapporté et fixé dans le boîtier 1.In a non-limiting embodiment, the lighting and / or signaling device 10 further comprises a complementary structural element 23, called an exoskeleton. Said exoskeleton is attached and fixed in the housing 1.

Les différents éléments du dispositif d'éclairage et/ou de signalisation sont décrits en détail ci-après.The various elements of the lighting and / or signaling device are described in detail below.

Le boîtier 1 est adapté pour recevoir le ou les modules lumineux 5chacun avec leur dissipateur de chaleur 11, le générateur de flux d'air 15 et la platine support 19 de chacun des modules lumineux 5. Il délimite ainsi un volume intérieur pour recevoir tous ces éléments.The housing 1 is adapted to receive the light module or modules 5chacun with their heat sink 11, the air flow generator 15 and the support plate 19 of each of the light modules 5. It thus delimits an interior volume to receive all these elements.

La glace 3 est adaptée pour refermer le boîtier 1. Dans un mode de réalisation non limitatif, elle comporte une zone transparente 30 et une zone noire 32. La zone transparente 30 est une zone dite froide au niveau de laquelle il y a des risques de condensation ou de givrage sur sa surface interne. La zone noire 32 est un élément de style et permet de cacher l'intérieur du dispositif d'éclairage et/ou de signalisation 10. Bien entendu, dans un autre mode de réalisation non limitatif, la glace 3 peut être complètement transparente, sans zone noire.The ice-cream 3 is adapted to close the casing 1. In a non-limiting embodiment, it comprises a transparent zone 30 and a black zone 32. The transparent zone 30 is a so-called cold zone at which there are risks of condensation or icing on its inner surface. The black zone 32 is a stylistic element and makes it possible to hide the inside of the lighting and / or signaling device 10. Of course, in another non-limiting embodiment, the ice cream 3 may be completely transparent, without a zone black.

Dans un mode de réalisation non limitatif, un module lumineux 5 comprend au moins une surface optique et au moins une source lumineuse coopérant avec ladite surface optique pour former un faisceau lumineux.In a non-limiting embodiment, a light module 5 comprises at least one optical surface and at least one light source cooperating with said optical surface to form a light beam.

Comme illustré à la figure 1 dans un exemple non limitatif, le module lumineux 5 comprend :

  • une première source lumineuse 7 et une seconde source lumineuse 7'. La première source lumineuse 7 est, par exemple, une source lumineuse destinée à assurer une fonction photométrique de feu de route dite « high beam » en anglais. La seconde source lumineuse 7' destinée à assurer une fonction photométrique de feu de croisement, dite « low beam » en anglais.
  • une première surface optique 9 et une seconde surface optique 9' coopérant respectivement avec la première source lumineuse 7 et la seconde source lumineuse 7'. La première surface optique 9 est ici un réflecteur adapté pour réfléchir un rayon lumineux provenant de la première source lumineuse 7. La seconde surface optique 9' est ici un réflecteur adapté pour réfléchir un rayon lumineux provenant de la deuxième source lumineuse 7'. L'ensemble des rayons lumineux réfléchis forment un faisceau lumineux global.
  • Une troisième surface optique 9" qui est ici une lentille adaptée pour canaliser et orienter le faisceau lumineux global.
As illustrated in figure 1 in a non-limiting example, the light module 5 comprises:
  • a first light source 7 and a second light source 7 '. The first light source 7 is, for example, a light source for providing a photometric function of high beam in English. The second light source 7 'intended to provide a low beam photometric function in English.
  • a first optical surface 9 and a second optical surface 9 'cooperating respectively with the first light source 7 and the second light source 7'. The first optical surface 9 is here a reflector adapted to reflect a light beam coming from the first light source 7. The second optical surface 9 'is here a reflector adapted to reflect a light beam from the second light source 7 '. The set of reflected light rays form a global light beam.
  • A third optical surface 9 "which is here a lens adapted to channel and orient the overall light beam.

Dans un mode de réalisation non limitatif, les sources lumineuses 7, 7' sont une ou plusieurs puces émettrices semi-conductrices.In a non-limiting embodiment, the light sources 7, 7 'are one or more semiconductor emitter chips.

Dans une variante de réalisation non limitative, chaque puce émettrice semi-conductrice fait partie d'une diode électroluminescente. Par diode électroluminescente, on entend tout type de diodes électroluminescentes, que ce soit dans des exemples non limitatifs des LED (« Light Emitting Diode »), des OLED (« organic LED »), des AMOLED (Active-Matrix-Organic LED), ou encore des FOLED (Flexible OLED).In a non-limiting embodiment, each semiconductor emitter chip is part of a light-emitting diode. Light-emitting diode means any type of light-emitting diode, whether in non-limiting examples of LEDs ("Light Emitting Diode"), OLEDs ("organic LEDs"), AMOLEDs (Active-Matrix-Organic LEDs), or FOLED (Flexible OLED).

La première source lumineuse 7 et la seconde source lumineuse 7' sont montées sur une platine conductrice 8 qui transmet la chaleur émise par les sources lumineuses 7, 7' au dissipateur de chaleur 11..The first light source 7 and the second light source 7 'are mounted on a conductive plate 8 which transmits the heat emitted by the light sources 7, 7' to the heat sink 11.

La figure 1 représente une vue en coupe du dispositif d'éclairage et/ou de signalisation 10. Comme il a déjà été décrit, le dispositif d'éclairage et/ou de signalisation 10 comprend le générateur d'un flux d'air 15 adapté pour générer le flux d'air 17. Par «générateur de flux d'air », on entend un ventilateur adapté pour brasser un certain volume d'air en direction du dissipateur de chaleur 11. Le ventilateur 15 est ici fixé sur l'exosquelette 23. Il peut être fixé sur d'autres zones ou éléments du boitier.The figure 1 represents a sectional view of the lighting and / or signaling device 10. As already described, the lighting and / or signaling device 10 comprises the generator of an airflow 15 adapted to generate the air flow 17. By "air flow generator" is meant a fan adapted to stir a certain volume of air towards the heat sink 11. The fan 15 is here fixed on the exoskeleton 23. can be fixed on other areas or elements of the box.

Le dissipateur de chaleur 11 est adapté pour évacuer la chaleur dégagée en fonctionnement par le module lumineux 5. Il est donc physiquement liée à ce dernier.The heat sink 11 is adapted to evacuate the heat generated in operation by the light module 5. It is therefore physically linked to the latter.

Comme il est illustré à la figure 2, le dissipateur de chaleur 11 comporte une pluralité d'ailettes 13 à travers lesquelles traverse le flux d'air 17 provenant du générateur de flux d'air 15.As it is illustrated in figure 2 , the heat sink 11 has a plurality of fins 13 through which flows the air stream 17 from of the air flow generator 15.

Dans un mode de réalisation non limitatif, les ailettes 13 du dissipateur de chaleur 11 sont parallèles entre elles et espacées d'une première distance D1. Ainsi, le flux d'air 17 est divisé en une pluralité de flux secondaires par les ailettes 13 du dissipateur de chaleur 11. Chaque flux secondaire est réchauffé par lesdites ailettes 13.In a non-limiting embodiment, the fins 13 of the heat sink 11 are parallel to each other and spaced apart by a first distance D1. Thus, the air flow 17 is divided into a plurality of secondary flows by the fins 13 of the heat sink 11. Each secondary flow is heated by said fins 13.

Dans un mode de réalisation non limitatif, les ailettes 13 sont disposées selon un premier plan P1.In a non-limiting embodiment, the fins 13 are arranged in a first plane P1.

Le dissipateur de chaleur 11 dirige ensuite le flux d'air 17 vers la platine support 19.The heat sink 11 then directs the air flow 17 to the support plate 19.

Selon l'invention, la platine support 19 du module lumineux 5 est adaptée pour diriger le flux d'air 17 vers la glace 3. Cette platine support 19 du module lumineux reçoit le module lumineux 5 et le dissipateur de chaleur 11 qui lui est lié, autrement dit, le module lumineux 5 et son dissipateur de chaleur 11 sont fixés sur la platine support 19. Elle a également une fonction esthétique.According to the invention, the support plate 19 of the light module 5 is adapted to direct the air flow 17 to the ice 3. This support plate 19 of the light module receives the light module 5 and the heat sink 11 which is linked thereto in other words, the light module 5 and its heat sink 11 are fixed on the support plate 19. It also has an aesthetic function.

Dans un premier mode de réalisation, la platine support 19 du module lumineux 5 est fixe par rapport au boîtier 1.In a first embodiment, the support plate 19 of the light module 5 is fixed relative to the housing 1.

Dans un deuxième mode de réalisation, préféré, la platine support 19 du module lumineux 5 est montée mobile par rapport au boîtier 1 de sorte à pivoter en fonction d'un virage ou à s'incliner en fonction de l'assiette du véhicule automobile portant le dispositif d'éclairage et/ou de signalisation. Pour cela, le dispositif d'éclairage et/ou de signalisation 10 comporte un ou plusieurs moteurs et un système de biellette (non illustrés). Le ou les moteurs sont asservis à l'angle de rotation du volant de direction du véhicule de sorte à faire pivoter le dispositif d'éclairage et/ou de signalisation en fonction d'un virage. De la même manière, le ou les moteurs peuvent être asservis à l'assiette du véhicule.In a second embodiment, preferred, the support plate 19 of the light module 5 is mounted movably relative to the housing 1 so as to pivot according to a turn or to tilt according to the attitude of the motor vehicle carrying the lighting and / or signaling device. For this, the lighting and / or signaling device 10 comprises one or more motors and a rod system (not shown). The motor or motors are slaved to the angle of rotation of the steering wheel of the vehicle so as to rotate the lighting device and / or signaling according to a turn. In the same way, the engine (s) can be slaved to the attitude of the vehicle.

Dans des modes de réalisation non limitatifs, le matériau formant la platine support 19 est :

  • du pbt (polybutylène téréphtalate) ; ou
  • du polyamide chargé de fibres de verre (connu sous le nom de gf30) ; ou
  • un plastique moulable rigide ; ou
  • en aluminium ; ou

In non-limiting embodiments, the material forming the platinum support 19 is:
  • pbt (polybutylene terephthalate); or
  • glass filled polyamide (known as gf30); or

  • in steel.

Tel qu'illustré sur la figure 1, la platine support 19 du module lumineux 5 comporte une partie avant 20a et une partie arrière 20b. La partie avant 20a est orientée vers la glace 3 et comprend une pluralité d'interstices 21 adaptés pour diriger le flux d'air 17 vers une glace 3. La partie arrière 20b forme avec une paroi interne du dispositif d'éclairage et/ou de signalisation 10 un conduit pour le guidage du flux d'air 17 vers les interstices 21 de la partie avant 20a.As illustrated on the figure 1 , the support plate 19 of the light module 5 comprises a front portion 20a and a rear portion 20b. The front portion 20a is oriented towards the window 3 and comprises a plurality of interstices 21 adapted to direct the flow of air 17 to a window 3. The rear portion 20b forms with an inner wall of the lighting device and / or signaling 10 a conduit for guiding the air flow 17 to the interstices 21 of the front portion 20a.

Dans le mode de réalisation de la figure 1, la paroi interne appartient à l'élément complémentaire structurel 23, ici l'exosquelette.In the embodiment of the figure 1 , the inner wall belongs to the structural complementary element 23, here the exoskeleton.

Dans un autre mode de réalisation non limitatif, la paroi interne appartient au boîtier 1.In another non-limiting embodiment, the inner wall belongs to the housing 1.

Le conduit formé par la paroi interne (1 ou 23) et la partie arrière 20b de la platine support 19 du module lumineux 5 présente un espacement E1 (illustré sur la figure 1) suffisant pour guider le flux d'air 17 vers la partie avant 20a de la platine support 19. Dans un exemple non limitatif, l'espacement E1 est compris entre 20mm (millimètres) et 30mm. Cet espacement E1 présente une section S1 qui décroît en direction de la partie avant 20a de la platine support 19, ce qui accélère le flux d'air 17 en direction de cette partie avant 19a. En outre, comme il est visible à la figure 1, la platine support 19 et la paroi interne dirigent le flux d'air 17 en direction des interstices 21 de la partie avant 20a de la platine support 19.The duct formed by the inner wall (1 or 23) and the rear part 20b of the support plate 19 of the light module 5 has a spacing E1 (illustrated in FIG. figure 1 ) sufficient to guide the air flow 17 to the front portion 20a of the support plate 19. In a non-limiting example, the spacing E1 is between 20mm (millimeters) and 30mm. This spacing E1 has a section S1 which decreases towards the front portion 20a of the support plate 19, which accelerates the air flow 17 towards this front portion 19a. In addition, as it is visible to the figure 1 , the support plate 19 and the inner wall direct the flow of air 17 towards the interstices 21 of the front portion 20a of the support plate 19.

Les interstices 21 sont ici disposés selon un second plan P2.The interstices 21 are here arranged in a second plane P2.

Dans un mode de réalisation non limitatif, le second plan P2 des interstices 21 est parallèle au premier plan P1 des ailettes 13. Cela permet de réduire les turbulences dans le flux d'air 17.In a non-limiting embodiment, the second plane P2 interstices 21 is parallel to the first plane P1 of the fins 13. This reduces turbulence in the air flow 17.

Dans un autre mode de réalisation non limitatif (non illustré), le second plan P2 des interstices 21 est coplanaire au premier plan P1 des ailettes 13. Les ailettes 13 sont ainsi alignées avec les interstices 21. Cela permet d'éviter les pertes de vitesse du flux d'air 17.In another non-limiting embodiment (not shown), the second plane P2 of the interstices 21 is coplanar with the first plane P1 of the fins 13. The fins 13 are thus aligned with the interstices 21. This makes it possible to avoid the loss of speed. of the air flow 17.

La figure 5 représente une vue en perspective de la partie avant 20a de la platine support 19. Cette partie avant 20a comprend une grille 28. Cette grille 28 présente sur une partie inférieure une pluralité d'interstices 21. Les interstices 21 de la platine support 19 sont espacées entre elles d'une seconde distance D2.The figure 5 is a perspective view of the front portion 20a of the support plate 19. This front portion 20a comprises a gate 28. This gate 28 has on a lower portion a plurality of interstices 21. The interstices 21 of the support plate 19 are spaced apart between them a second distance D2.

Dans un mode de réalisation non limitatif, la première distance D1 entre deux ailettes adjacentes 13 du dissipateur de chaleur 11 est identique à la seconde distance D2 entre deux interstices de la grille 28. De cette manière, chaque flux secondaire formé par le dissipateur de chaleur 11 va pouvoir passer dans un interstice 21 de la platine support. Il existe ainsi pour chaque flux secondaire un couple paire d'ailettes adjacentes/interstice associé. On favorise ainsi la circulation des flux secondaires et on limite en conséquence les pertes de charge du flux 17. Il y ainsi moins de turbulences créées et un meilleur échange thermique.In a non-limiting embodiment, the first distance D1 between two adjacent fins 13 of the heat sink 11 is identical to the second distance D2 between two interstices of the grid 28. In this way, each secondary flow formed by the heat sink 11 will be able to pass in a gap 21 of the support plate. There is thus for each secondary flow a pair of adjacent fins pair / interstice associated. This promotes the circulation of secondary flows and therefore limits the pressure losses of the stream 17. There is less turbulence created and better heat exchange.

Dans un mode de réalisation non limitatif, le nombre d'interstices 21 de la platine support 19 est supérieur au nombre d'ailettes 13 du dissipateur de chaleur 11. Cela produit un effet de style visible par un observateur extérieur au véhicule automobile.In a non-limiting embodiment, the number of interstices 21 of the support plate 19 is greater than the number of fins 13 of the heat sink 11. This produces a style effect visible by an observer outside the motor vehicle.

Dans un mode de réalisation non limitatif, la platine support 19 comprend des ouvertures 22 pour le passage de vis de fixation pour la fixation de la platine support 19 au reste du dispositif d'éclairage et/ou de signalisation 1.In a non-limiting embodiment, the support plate 19 comprises openings 22 for the passage of fixing screws for fixing the support plate 19 to the rest of the lighting and / or signaling device 1.

La figure 6 représente une vue en coupe d'un interstice 21 de la partie avant 20a de la platine support 19 du module lumineux 5 selon un mode de réalisation non limitatif. Cet interstice 21 est formé par une entrée 210 (par laquelle le flux d'air 17 pénètre), une sortie 211 (par laquelle le flux d'air 17 sort) et deux parois 212, 213 reliant l'entrée 210 et la sortie 211. L'entrée 210 présente une section S2 et la sortie 211 présente une section S3.The figure 6 represents a sectional view of a gap 21 of the front portion 20a of the support plate 19 of the light module 5 according to a non-limiting embodiment. This gap 21 is formed by an inlet 210 (by which the air flow 17 enters), an outlet 211 (through which the airflow 17 exits) and two walls 212, 213 connecting the inlet 210 and the outlet 211. The inlet 210 has a section S2 and the output 211 has a section S3.

Dans un mode de réalisation non limitatif, la section S3 de la sortie 211 est supérieure à la section S2 de l'entrée 210. De cette manière, on vient créer un effet venturi au niveau de l'interstice 21. Cet effet venturi permet d'augmenter la vitesse d'écoulement du flux d'air 17 en direction de la glace 3. Par cette augmentation de vitesse, on améliore le dégivrage et/ou la suppression de la condensation de cette glace 3. On réduit ainsi le temps pour enlever la condensation et/ou le temps de dégivrage.In a non-limiting embodiment, the section S3 of the outlet 211 is greater than the section S2 of the inlet 210. In this way, it comes to create a venturi effect at the gap 21. This venturi effect makes it possible to increase the speed of flow of the air flow 17 towards the ice 3. By this increase in speed, it improves the defrosting and / or the removal of the condensation of the ice 3. This reduces the time to remove condensation and / or defrosting time.

Dans un mode de réalisation non limitatif, les parois 212, 213 sont planes de sorte à favoriser l'écoulement du flux d'air et à limiter les pertes de charge. Comme cela est visible à la figure 6, les parois 212, 213 de l'interstice 21 forment un angle α avec une direction X, correspondant à la direction d'avancement du véhicule.In a non-limiting embodiment, the walls 212, 213 are flat so as to promote the flow of the air flow and to limit the pressure drops. As can be seen in figure 6 , the walls 212, 213 of the gap 21 form an angle α with a direction X, corresponding to the direction of travel of the vehicle.

Dans un premier mode de réalisation non limitatif, l'angle α est constant et les parois 212, 213 de l'interstice sont fixes.In a first nonlimiting embodiment, the angle α is constant and the walls 212, 213 of the interstice are fixed.

Dans un deuxième mode de réalisation non limitatif, l'angle α varie et les parois 212, 213 de l'interstice 21 sont mobiles. Pour rendre mobile ces parois 212, 213, le dispositif d'éclairage et/ou de signalisation 10 comporte un moteur (non illustré) et un système de biellettes (non illustré) relié aux parois de l'interstice 21. De cette manière, il est possible de diriger le flux 17 sur des zones de la glace déterminées. On améliore ainsi le dégivrage et/ou le temps pour enlever la condensation de ces zones déterminées de la glace 3.In a second nonlimiting embodiment, the angle α varies and the walls 212, 213 of the gap 21 are movable. To make these walls 212, 213 mobile, the lighting and / or signaling device 10 comprises a motor (not shown) and a connecting rod system (not shown) connected to the walls of the gap 21. In this way, it It is possible to direct the stream 17 on specific areas of the ice. This improves the defrosting and / or the time to remove the condensation of these determined areas of ice 3.

Pour améliorer le dégivrage et/ou le temps pour enlever la condensation de la glace 3, dans un mode de réalisation non limitatif, le dispositif d'éclairage et/ou de signalisation 10 comporte en outre une source de chaleur complémentaire (non illustrée). De cette manière, il est possible de dégivrer et/ou d'enlever la condensation présente sur la glace 3 à froid, à savoir :

  • sans mettre en fonctionnement les sources lumineuses 7, 7' du module lumineux 5, par exemple au démarrage du véhicule ;
  • lorsque les sources lumineuses 7, 7' du module lumineux 5 viennent d'être allumées, le temps que le dissipateur de chaleur 11 évacuent les calories venant du module lumineux 5 en fonctionnement.
To improve the defrost and / or the time to remove the condensation of the ice 3, in a non-limiting embodiment, the lighting and / or signaling device 10 further comprises a complementary source of heat (not shown). In this way, it is possible to defrost and / or remove the condensation present on the ice 3 cold, namely:
  • without operating the light sources 7, 7 'of the module light 5, for example when starting the vehicle;
  • when the light sources 7, 7 'of the light module 5 have just been turned on, the time that the heat sink 11 dissipates the calories coming from the light module 5 in operation.

Dans un mode de réalisation non limitatif, la source de chaleur complémentaire est une résistance chauffante.In a non-limiting embodiment, the complementary heat source is a heating resistor.

Dans un mode de réalisation non limitatif, la source de chaleur complémentaire est disposée dans le flux d'air 17 sur la paroi interne sur laquelle on fait passer le flux d'air 17, en amont ou en aval des interstices 21. Dans des exemples non limitatifs, la source de chaleur complémentaire est fixée sur l'exosquelette 23 ou sur le boîtier 1.In a non-limiting embodiment, the complementary heat source is disposed in the air flow 17 on the inner wall on which the flow of air 17 is passed, upstream or downstream of the interstices 21. In examples non-limiting, the complementary heat source is fixed on the exoskeleton 23 or on the housing 1.

Dans un mode de réalisation non limitatif, le dispositif d'éclairage et/ou de signalisation 10 comporte en outre au moins un masque qui a une fonction esthétique.In a non-limiting embodiment, the lighting and / or signaling device 10 further comprises at least one mask which has an aesthetic function.

Comme illustré à la figure 1, le dispositif d'éclairage et/ou de signalisation 10 comporte un masque 27 disposé le long d'un support de guide de lumière 33 (décrit plus loin) et un masque 29 disposé entre la platine support 19 et le glace 3.As illustrated in figure 1 , the lighting and / or signaling device 10 comprises a mask 27 disposed along a light guide support 33 (described below) and a mask 29 disposed between the support plate 19 and the ice-cream 3.

Le masque 29 définit avec la surface optique 9', un espacement E4 présentant une section S4 suffisante pour le passage du flux d'air.The mask 29 defines with the optical surface 9 ', a spacing E4 having a section S4 sufficient for the passage of the air flow.

Il permet ainsi de guider le flux d'air 17 provenant de la platine support 19 vers la partie supérieure de la glace 3. Dans un exemple non limitatif, l'espacement E4 est compris entre 10mm et 15mm.It thus makes it possible to guide the flow of air 17 coming from the support plate 19 towards the upper part of the window 3. In a nonlimiting example, the spacing E4 is between 10 mm and 15 mm.

Dans un mode de réalisation non limitatif, le masque 29 est disposé par rapport à la glace 3 de sorte à empêcher le passage d'une partie du flux d'air 17 entre ce masque 29 et la glace 3. On s'assure ainsi que l'ensemble du flux d'air 17 provenant de la platine support 19 est guidé vers les zones 30, 32 de la glace 3 à dégivrer et/ou à enlever la condensation.In a non-limiting embodiment, the mask 29 is disposed relative to the ice 3 so as to prevent the passage of a portion of the air flow 17 between the mask 29 and the ice 3. This ensures that the entire air flow 17 from the support plate 19 is guided to the zones 30, 32 of the ice 3 to defrost and / or to remove the condensation.

Dans un mode de réalisation non limitatif, tel qu'illustré sur la figure 1, le dispositif d'éclairage et/ou de signalisation 10 comprend en outre un guide de lumière 31 et un support de guide de lumière 33. Le support de guide de lumière 33 est disposé par rapport à une partie supérieure 35 de la glace 3 de sorte à avoir un espacement E5, présentant une section S5. Cet espacement E5 est suffisant pour laisser passer le flux d'air 17 le long de la partie supérieure 35 de la glace 3. On assure ainsi l'évacuation du flux d'air 17 hors du dispositif d'éclairage et/ou de signalisation 10, une fois l'opération de dégivrage et/ou d'enlèvement de la condensation effectuée. Dans un exemple non limitatif, l'espacement E5 est au minimum égal à 5mm.In a non-limiting embodiment, as illustrated on the figure 1 , the The lighting and / or signaling device 10 further comprises a light guide 31 and a light guide support 33. The light guide support 33 is arranged with respect to an upper portion 35 of the window 3 so as to have a spacing E5, having a section S5. This spacing E5 is sufficient to allow the air flow 17 to pass along the upper part 35 of the ice 3. This ensures the evacuation of the air stream 17 from the lighting and / or signaling device 10 , once the defrosting operation and / or removal of the condensation carried out. In a non-limiting example, the spacing E5 is at least equal to 5 mm.

Bien entendu la description de l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus.
Ainsi, dans un mode de réalisation non limitatif, le dispositif d'éclairage et/ou de signalisation 10 peut être bi-modules, c'est-à-dire qu'il peut comprendre deux modules lumineux 5 montés sur leur platines supports 19 chaque module lumineux 5 étant associé à une ventilateur 15 respectivement. Les deux platines supports 19 coopèrent avec chacun des ventilateurs 15 et des modules lumineux 5 comme décrit précédemment et comportent ainsi des interstices 21 tels que décrits précédemment pour diriger le flux d'air 17 vers la glace 3. Selon une variante préférée, pour des raisons d'optimisation de coût, on ne peut prévoir qu'un seul ventilateur 15 commun aux deux modules lumineux 5. Dans cette variante, on peut définir qu'une seule des deux platines supports 19 comporte des interstices 21 tels que décrits précédemment pour diriger le flux d'air 17 vers la glace 3. L'autre platine comporte alors une partie avant 20a pleine, sans interstices 21. Dans ce cas, la platine support 19 avec les interstices 21 coopéra plus particulièrement avec le module lumineux 5 dont les sources lumineuses 7, 7' dégagent le plus de calories en fonctionnement.Of course, the description of the invention is not limited to the embodiments described above.
Thus, in a non-limiting embodiment, the lighting and / or signaling device 10 may be bi-modules, that is to say it may comprise two light modules 5 mounted on their support plates 19 each light module 5 being associated with a fan 15 respectively. The two support plates 19 cooperate with each of the fans 15 and light modules 5 as previously described and thus comprise gaps 21 as described above for directing the flow of air 17 to the ice 3. According to a preferred variant, for reasons of In this variant, it is possible to define only one of the two support plates 19 to have interstices 21 as described above for directing the system. air flow 17 to the ice 3. The other plate then has a front portion 20a full, without gaps 21. In this case, the support plate 19 with the interstices 21 cooperates more particularly with the light module 5 whose light sources 7, 7 'release the most calories in operation.

Dans une première variante de réalisation non limitative de ce mode, un module lumineux 5 est configuré pour réaliser la fonction photométrique de feu de route dite « high beam » et l'autre module lumineux est adapté pour réaliser la fonction photométrique de feu de croisement dite « low beam ». Dans une deuxième variante de réalisation non limitative de ce mode, chaque module lumineux 5 est adapté pour réaliser une partie de la fonction photométrique de feu de route et une partie de la fonction photométrique de feu de croisement. Ainsi, chaque module lumineux 5 comprend des sources lumineuses 7 et 7' (décrites précédemment).In a first non-limiting embodiment of this embodiment, a light module 5 is configured to perform the photometric function of so-called "high beam" and the other light module is adapted to perform the low beam light beam photometric function. In a second non-limiting embodiment of this embodiment, each light module 5 is adapted to perform part of the photometric function of the high beam and part of the photometric function of the low beam. Thus, each light module 5 comprises light sources 7 and 7 '(previously described).

Cela permet d'optimiser la puissance des sources lumineuses 7 et 7' car on répartit la puissance des sources lumineuses associées à une fonction photométrique sur deux modules lumineux 5.This makes it possible to optimize the power of the light sources 7 and 7 'because the power of the light sources associated with a photometric function is distributed over two light modules 5.

On notera que le faisceau lumineux produit pour réaliser la fonction photométrique de feu de croisement dite « low beam » est à coupure. Il comporte ainsi deux segments dont l'un est horizontal et l'autre incliné. Ainsi, dans cette deuxième variante, un des modules lumineux 5 comprend les sources lumineuses 7' pour réaliser le segment incliné, à savoir pour réaliser une sous-fonction appelée « kink »en anglais, et l'autre module lumineux 5 comprend les sources lumineuses 7' pour réaliser le segment horizontal, à savoir pour réaliser une sous-fonction appelée « flat »en anglais.It will be noted that the light beam produced to perform the photometric function of low beam passing light is cutoff. It thus comprises two segments, one of which is horizontal and the other inclined. Thus, in this second variant, one of the light modules 5 comprises the light sources 7 'for producing the inclined segment, namely to produce a sub-function called "kink" in English, and the other light module 5 comprises the light sources 7 'to achieve the horizontal segment, namely to achieve a sub-function called "flat" in English.

Ainsi, l'invention décrite présente notamment les avantages suivants :

  • il est possible de dégivrer et/ou d'enlever la condensation efficacement des zones froides de la glace en utilisant des calories provenant d'un module lumineux appartenant au dispositif d'éclairage et/ou de signalisation. Les performances optiques du dispositif d'éclairage et/ou de signalisation ne sont ainsi plus dégradées par la condensation ou le givre, et il n'existe plus de problème esthétique car il n'existe plus de gouttes de condensation sur la surface interne de la glace 3;
  • le flux d'air est dirigé par l'intermédiaire d'une platine support qui est une pièce préexistante dans le boîtier. Il n'est pas ainsi nécessaire d'avoir recours à conduit spécifique supplémentaire pour assurer la circulation de l'air, ce qui permet d'optimiser les coûts de fabrication du dispositif d'éclairage et/ou de signalisation ;
  • pour améliorer le dégivrage et/ou l'enlèvement de la condensation de la glace, le flux d'air est accéléré simplement dans la platine support par des interstices qui présentent des formes et des inclinaisons spécifiques ;
  • les espacements entre les différents éléments du dispositif d'éclairage et/ou de signalisation sont optimisés de sorte à limiter les pertes de charge du flux d'air ;
  • il n'est pas nécessaire d'installer une pièce supplémentaire comme dans l'art antérieur ;
  • la platine support est ouverte grâce aux interstices, ce qui améliore la circulation de l'air vers la zone froide de la glace, contrairement à une platine support avec une partie avant 20a pleine.
Thus, the invention described has the following advantages:
  • it is possible to effectively defrost and / or remove condensation from cold areas of the ice by using calories from a light module belonging to the lighting and / or signaling device. The optical performance of the lighting and / or signaling device is thus no longer degraded by condensation or frost, and there is no longer any aesthetic problem because there are no longer drops of condensation on the internal surface of the ice 3;
  • the air flow is directed through a support plate which is a pre-existing part in the housing. It is not necessary to use additional specific conduit to ensure the circulation from the air, which makes it possible to optimize the manufacturing costs of the lighting and / or signaling device;
  • to improve defrosting and / or removal of condensation from ice, the air flow is accelerated simply in the support plate by interstices which have specific shapes and inclinations;
  • the spacings between the different elements of the lighting and / or signaling device are optimized so as to limit the pressure drops of the air flow;
  • it is not necessary to install an additional part as in the prior art;
  • the support plate is opened thanks to the interstices, which improves the circulation of the air towards the cold zone of the ice, contrary to a support plate with a front part 20a full.
