Description

FEU DE SIGNALISATION DE VEHICULE AUTOMOBILE SIGNALING LIGHT OF MOTOR VEHICLE
La présente invention concerne un feu de signalisation pour un véhicule automobile.The present invention relates to a traffic light for a motor vehicle.
L'invention concerne plus particulièrement un feu, notamment arrière, de véhicules automobiles, comportant au moins une lampe et un porte-lampe associé, capables d'évacuer de la chaleur générée par la source lumineuse du feu de signalisation.The invention relates more particularly to a fire, in particular a rear light, of motor vehicles, comprising at least one lamp and an associated lamp holder, capable of evacuating the heat generated by the light source of the signaling light.
Les véhicules automobiles comprennent généralement des feux de signalisation qui, suivant leur fonction brouillard, recul, clignotant ou éclairage, comportent des lampes de puissances différentes, qui sont de plus ou moins importantes sources de chaleur.Motor vehicles generally include traffic lights which, according to their function fog, recoil, flashing or lighting, include lamps of different powers, which are more or less important sources of heat.
Ainsi, lors du fonctionnement des sources lumineuses, la chaleur produite par ces dernières, s'accumule dans le dispositif d'éclairage et il est nécessaire d'évacuer cette chaleur afin d'éviter les risques d'endommagement voir d'inflammation du dispositif.Thus, during the operation of the light sources, the heat produced by the latter, accumulates in the lighting device and it is necessary to remove this heat to avoid the risk of damage or inflammation of the device.
Le document EP 1 718 127 propose un feu avant produisant de la chaleur pour éliminer la condensation dans le boîtier de phare. Ce feu comporte différents orifices permettant d'obtenir un flux d'air à l'intérieur du boîtier de manière à évacuer cette chaleur. Un tel boîtier propose un volume intérieur important afin de permettre un flux d'air important entre les orifices.EP 1 718 127 proposes a front light producing heat to eliminate condensation in the headlight housing. This fire has different orifices for obtaining an air flow inside the housing so as to evacuate this heat. Such a housing provides a large interior volume to allow a large air flow between the orifices.
Cependant, certains feux de signalisation, tels que les feux arrière, doivent être suffisamment compact pour s'intégrer dans la structure du véhicule et ne permettent d'avoir un volume intérieur suffisant pour obtenir un flux d'air pouvant évacuer la chaleur produite par les sources lumineuses.However, some traffic lights, such as taillights, must be compact enough to fit into the vehicle structure and allow sufficient interior volume to provide a flow of air that can remove the heat produced by the vehicles. light sources.
Ainsi certaines solutions de limitation de l'accumulation de la chaleur proposent un porte-lampe creux formant un volume limitant la surchauffe du dispositif d'éclairage au niveau des douilles des ampoules en favorisant les mouvements d'air dans le porte-lampe.Thus, some solutions for limiting the accumulation of heat provide a hollow lamp holder forming a volume limiting the overheating of the lighting device at the bulb sockets by promoting the movement of air in the lamp holder.
Cependant, comme précédemment, l'architecture de certains véhicules nécessite un porte-lampe compact ne permettant pas de créer un volume suffisant pour limiter la surchauffe du dispositif d'éclairage. Le but de l'invention, est de proposer un feu de signalisation amélioré de véhicule automobile permettant une meilleure évacuation de la chaleur générée par les sources lumineuses malgré la compacité du feu nécessaire à son intégration sur le véhicule.However, as before, the architecture of some vehicles requires a compact lamp holder does not allow to create a sufficient volume to limit the overheating of the lighting device. The object of the invention is to provide an improved traffic signal of a motor vehicle for better evacuation of the heat generated by the light sources despite the compactness of the fire necessary for its integration on the vehicle.
Dans ce but, l'invention propose un boîtier de feu de signalisation de véhicule automobile comprenant un porte-lampe comportant un moyen de canalisation de la chaleur produite par les lampes en dehors du boîtier.For this purpose, the invention proposes a motor vehicle traffic light box comprising a lamp holder comprising a means for channeling the heat produced by the lamps outside the housing.
Selon d'autres caractéristiques de l'invention, le moyen de canalisation de la chaleur peut être une rainure ouverte sur la face intérieur du porte-lampe et s'étendant verticalement d'une zone inférieure vers une zone supérieure du porte-lampe.According to other features of the invention, the heat channeling means may be an open groove on the inner face of the lamp holder and extending vertically from a lower zone to an upper zone of the lamp holder.
Le porte-lampe peut comporter au moins deux douilles alignées suivant un axe vertical, et deux rainures s'étendant de part et d'autre des douilles.The lamp holder may comprise at least two sockets aligned along a vertical axis, and two grooves extending on either side of the sockets.
Une portion inférieure du porte-lampe peut relier les rainures ensemble, et peut comporter une ouverture formant une entrée d'air vers l'intérieur du boîtier.A lower portion of the lamp holder may connect the grooves together, and may include an opening forming an air inlet to the interior of the housing.
L'extrémité supérieure de chaque rainure peut déboucher sur l'ouverture pour le connecteur électrique du feu de signalisation.The upper end of each groove can lead to the opening for the electrical connector of the traffic light.
L'invention sera désormais décrite dans un exemple en référence aux dessins annexés suivants :The invention will now be described in an example with reference to the following appended drawings:
- la figure 1 est une vue en coupe verticale d'un boîtier de feu de signalisation selon l'invention;- Figure 1 is a vertical sectional view of a signal light box according to the invention;
- la figure 2 est une vue de la face arrière du porte-lampe du boîtier de la figure 1 ; etFIG. 2 is a view of the rear face of the lamp holder of the casing of FIG. 1; and
- la figure 3 est une vue en coupe selon l'axe III du porte-lampe de la figure 2.- Figure 3 is a sectional view along the axis III of the lamp holder of Figure 2.
En référence aux figures, un dispositif d'éclairage 10 pour un véhicule automobile tel qu'un feu de signalisation arrière, est fixé sur un élément de structure 12 d'un côté arrière du véhicule. Ce feu de signalisation 10 possède différentes lampes 16a, 16b et 16c pour assurer par exemple les fonctions de recul, de clignotant ou de freinage. Ce feu de signalisation 10 se présente sous la forme d'un boîtier dont la partie principale est un ensemble réflecteur de lumière 14 vers l'extérieur du véhicule comportant trois réflecteurs 14a, 14b et 14c situés les uns au dessus des autres sur un axe vertical, et présentant une forme essentiellement parabolique ouverte vers l'extérieur du véhicule et dont le fond comporte un passage pour la lampe associée 16a, 16b ou 16c.Referring to the figures, a lighting device 10 for a motor vehicle such as a rear traffic light, is attached to a structural member 12 of a rear side of the vehicle. This signal light 10 has different lamps 16a, 16b and 16c to provide for example the functions of recoil, flashing or braking. This traffic light 10 is in the form of a housing whose main part is a light reflector assembly 14 towards the outside of the vehicle comprising three reflectors 14a, 14b and 14c located one above the other on a vertical axis , and having a substantially parabolic shape open towards the outside of the vehicle and whose bottom has a passage for the associated lamp 16a, 16b or 16c.
L'ensemble réflecteur de lumière 14 est réalisé en matière plastique et les faces avants des réflecteurs de lumière 14a 14b et 14c, positionnées du côté des lampes vers l'extérieur du véhicule sont recouvertes d'un revêtement réfléchissant la lumière.The light reflecting assembly 14 is made of plastic material and the front faces of the light reflectors 14a 14b and 14c, positioned on the lamp side towards the outside of the vehicle are covered with a light reflective coating.
Les deux réflecteurs inférieurs 14b et 14c présente chacun un orifice 18 sur leur partie supérieure. Ces orifices 18 débouchent à l'arrière de l'ensemble réflecteur 14, permettant ainsi un flux de transfert de la chaleur de l'avant vers l'arrière du réflecteur.The two lower reflectors 14b and 14c each have an orifice 18 on their upper part. These orifices 18 open at the rear of the reflector assembly 14, thus allowing a heat transfer flow from the front to the rear of the reflector.
L'ensemble réflecteur de lumière 14 comprend des sites de fixation 20 situés sur le bord périphérique dudit ensemble réflecteur. Ces sites de fixation 20 permettent de fixer le boîtier sur la structure 12 du véhicule par l'intermédiaire de vis par exemple.The light reflector assembly 14 includes attachment sites 20 located on the peripheral edge of said reflector assembly. These attachment sites 20 make it possible to fix the housing on the structure 12 of the vehicle by means of screws for example.
La partie arrière de l'ensemble réflecteur en regard avec l'élément de structure 12, possède des parois 26 formant sensiblement un volume parallélépipédique, sur lesquelles le support 22 des lampes est fixé de manière à obtenir un volume fermé. Ce support est aussi appelé porte-lampe 22.The rear part of the reflector assembly facing the structural element 12, has walls 26 substantially forming a parallelepiped volume, on which the support 22 of the lamps is fixed so as to obtain a closed volume. This support is also called lamp holder 22.
Par ailleurs, le boîtier du feu de signalisation 10 est fermé du côté extérieur du véhicule par une vitre catadioptrique 24 en polycarbonate par exemple. Cette vitre 24 est fixée à la périphérie du réflecteur de lumière 14 par exemple par collage, emboîtement ou tout autre moyen d'assemblage.Furthermore, the housing of the traffic light 10 is closed on the outside of the vehicle by a catadioptric window 24 polycarbonate for example. This window 24 is fixed to the periphery of the light reflector 14 for example by gluing, interlocking or any other means of assembly.
Le porte-lampe 22 forme un couvercle qui comporte trois douilles 28a, 28b et 28c ouvertes sur la face avant du porte-lampe tournée vers l'intérieur du boîtier du feu de signalisation.The lamp holder 22 forms a lid which has three sockets 28a, 28b and 28c open on the front face of the lamp holder turned towards the inside of the signal light housing.
Les bords du porte-lampe 22 sont maintenus contre les parois 26 par des moyens de fixation (non représentés) par exemple des clips ou des vis. Les douilles 28a, 28b et 28c sont disposées sur un même axe vertical en regard des trois passages des réflecteurs 14a, 14b et 14c.The edges of the lamp holder 22 are held against the walls 26 by fastening means (not shown), for example clips or screws. The sockets 28a, 28b and 28c are arranged on the same vertical axis facing the three passages of the reflectors 14a, 14b and 14c.
Le porte-lampe 22 comprend une ouverture de connexion électrique 30 qui débouche la face arrière du porte-lampe 22 en regard de la carrosserie 12 du véhicule. Dans cet exemple, l'ouverture de connexion 30 se situe entre la douille supérieure 28a et les douilles inférieures 28b et 28c, les lampes inférieures 16b et 16c étant les plus importantes sources de chaleur du feu de signalisation. Cette connexion électrique 30 est reliée électriquement aux douilles 26 par l'intermédiaire d'un circuit électrique (non représenté) positionné sur la face avant du porte-lampe 22.The lamp holder 22 comprises an electrical connection opening 30 which opens the rear face of the lamp holder 22 facing the bodywork 12 of the vehicle. In this example, the connection opening 30 is between the upper bushing 28a and the lower bushings 28b and 28c, the lower lamps 16b and 16c being the most important heat sources of the traffic light. This electrical connection 30 is electrically connected to the sockets 26 via an electrical circuit (not shown) positioned on the front face of the lamp holder 22.
Le porte-lampe 22 comporte deux rainures 32 ouvertes sur sa face avant et s'étendant verticalement de chaque coté des deux douilles inférieures 28b et 28c jusqu'à l'ouverture de la connexion électrique.The lamp holder 22 has two grooves 32 open on its front face and extending vertically on each side of the two lower sockets 28b and 28c until the opening of the electrical connection.
Le porte-lampe 22 comporte aussi une entrée d'air 34 dans sa partie inférieure. Cette entrée d'air 34 est constituée d'une ouverture en forme de cercle, tronqué dans sa partie inférieure. L'ouverture est surmontée d'une paroi cylindrique dont une portion située vers le bas n'est pas fermée. Une paroi verticale perpendiculaire à la partie tronquée de l'ouverture rejoint la paroi cylindrique. La hauteur de cette paroi verticale est inférieure à la hauteur de la paroi cylindrique. Afin d'éviter l'introduction de fluide dans le boîtier, cette ouverture est associée à un capuchon inséré sur cette paroi cylindrique jusqu'à une distance de quelques millimètre de la face du porte-lampe 22 de manière à laisser une portion ouverte de la paroi libre. Un filtre à poussière peut être placé entre le capuchon et la paroi verticale.The lamp holder 22 also has an air inlet 34 in its lower part. This air inlet 34 consists of an opening in the shape of a circle, truncated in its lower part. The opening is surmounted by a cylindrical wall of which a portion located downward is not closed. A vertical wall perpendicular to the truncated portion of the opening joins the cylindrical wall. The height of this vertical wall is less than the height of the cylindrical wall. In order to prevent the introduction of fluid into the housing, this opening is associated with a cap inserted on this cylindrical wall up to a distance of a few millimeters from the face of the lamp holder 22 so as to leave an open portion of the free wall. A dust filter can be placed between the cap and the vertical wall.
Le fonctionnement de l'invention est le suivant :The operation of the invention is as follows:
Lors du fonctionnement du feu de signalisation 10 les lampes, en particulier les lampes inférieures 16b et 16c dans cet exemple, produisent de la chaleur qui s'accumule dans le boîtier du feu de signalisation 10.During operation of the signaling light 10 the lamps, in particular the lower lamps 16b and 16c in this example, produce heat which accumulates in the housing of the traffic light 10.
Cette chaleur est canalisée par u flux d'air circulant dans les rainures 32 vers l'ouverture de la connexion électrique 30 permettant ainsi d'évacuer la chaleur vers l'extérieur du boîtier. Afin d'améliorer la circulation d'air les rainures 32 sont liés à l'entrée d'air 34 situé dans une zone inférieure du porte-lampe 22.This heat is channeled by a flow of air flowing in the grooves 32 to the opening of the electrical connection 30 thus allowing the heat to be discharged to the outside of the housing. In order to improve the air flow, the grooves 32 are connected to the air inlet 34 situated in a lower zone of the lamp holder 22.
Ainsi, l'utilisation d'un porte-lampe 22 comprenant des rainures 32 permet avantageusement d'obtenir une bonne évacuation de la chaleur produite par les sources lumineuses tout en conservant une compacité suffisante pour l'intégration du boîtier de feu de signalisation sur la structure du véhicule. Thus, the use of a lamp holder 22 comprising grooves 32 advantageously makes it possible to obtain a good evacuation of the heat produced by the light sources while maintaining a sufficient compactness for the integration of the signaling light box onto the light source. vehicle structure.
