Description

DISPOSITIF D'ECLAIRAGE DE VEHICULE  VEHICLE LIGHTING DEVICE

La présente invention concerne de manière générale un dispositif d'éclairage, et plus précisément un dispositif d'éclairage de la route, destiné à être monté sur un véhicule automobile. The present invention generally relates to a lighting device, and more specifically to a road lighting device, intended to be mounted on a motor vehicle.

Il est connu dans l'art antérieur des dispositifs d'éclairage de la route montés sur un véhicule automobile. Ces dispositifs font généralement partie d'un projecteur ou phare situé à l'avant du véhicule et projetant un faisceau lumineux vers l'avant du véhicule pour éclairer la route. De manière générale ces dispositifs comprennent une source de lumière, pour les éclairages à base de diode électroluminescente une carte de circuit imprimé, une lentille pour projeter la lumière émise vers l'avant et une glace située devant pour protéger le dispositif. Un problème de ces dispositifs est que la glace peut être embuée par condensation en fonction du climat et de la température extérieure. Ainsi afin d'empêcher cette condensation sur la glace, il a été trouvé d'installer un système de ventilation qui utilise la chaleur de la carte de circuit imprimé récupérée par des radiateurs situés à l'arrière de la carte pour réchauffer la glace et empêcher la condensation. Alternativement, il est commun d'appliquer un vernis anti-condensation sur la glace. Un problème de ces techniques est qu'elles ne sont pas économiques et qu'elles complexifient grandement le dispositif d'éclairage dans le cas du système de ventilation ou qu'elles ne sont pas économiques dans le cas de l'application du vernis.  It is known in the prior art of road lighting devices mounted on a motor vehicle. These devices are usually part of a headlamp or headlamp located at the front of the vehicle and projecting a light beam towards the front of the vehicle to illuminate the road. In general, these devices comprise a light source, for light-emitting diode-based lighting, a printed circuit board, a lens for projecting light emitted forwards and an ice-cream placed in front to protect the device. A problem with these devices is that the ice can be misted by condensation depending on the climate and the outside temperature. Thus, in order to prevent this condensation on the ice, it has been found to install a ventilation system that uses the heat of the circuit board recovered by radiators located at the rear of the card to warm the ice and prevent the condensation. Alternatively, it is common to apply an anti-condensation coating on the ice. A problem of these techniques is that they are not economical and they greatly complexify the lighting device in the case of the ventilation system or they are not economical in the case of the application of the varnish.

Le document US20120314440 décrit un dispositif d'éclairage comprenant une carte de circuit imprimé (aussi appelée PCB), sur laquelle sont disposées des LED, qui possède des portions en cuivre pour évacuer la chaleur. Un des inconvénients connus des LED est d'émettre la chaleur vers l'arrière du composant, c'est-à-dire sur le PCB alors que pour éviter la condensation, il est avantageux de diffuser cette chaleur vers l'avant, c'est-à- dire la glace externe du projecteur. Ce type de dispositif est typiquement celui utilisé avec le système de ventilation qui va utiliser la chaleur du PCB puis l'envoyer par ventilation sur la glace. Comme décrit plus haut, ce type de dispositif est cependant très compliqué. The document US20120314440 describes a lighting device comprising a printed circuit board (also called PCB), on which LEDs are arranged, which has copper portions to evacuate the heat. One of the known drawbacks of LEDs is to emit heat towards the back of the component, ie on the PCB, whereas to avoid condensation, it is advantageous to diffuse this heat towards the front. that is, the outer mirror of the projector. This type of device is typically the one used with the ventilation system that will use the PCB heat then send it on the ice. As described above, this type of device is however very complicated.

Un but de la présente invention est de répondre aux inconvénients du document de l'art antérieur mentionné ci-dessus et en particulier, tout d'abord, de fournir un dispositif d'éclairage pour un véhicule capable d'éliminer la formation de condensation sur la glace et simple à mettre en œuvre.  An object of the present invention is to meet the disadvantages of the prior art document mentioned above and in particular, first of all, to provide a lighting device for a vehicle capable of eliminating the formation of condensation on ice and simple to implement.

Pour cela un premier aspect de l'invention concerne un dispositif d'éclairage de véhicule comprenant au moins une source de lumière agencée pour émettre de la lumière, une carte de circuit imprimé sur laquelle est montée la source de lumière, au moins une lentille agencée pour recevoir la lumière émise par la source de lumière et projeter un faisceau lumineux vers une glace du dispositif, et un moyen de fixation de la lentille sur la carte de circuit imprimé, caractérisé en ce que le moyen de fixation est agencé pour présenter une liaison thermique entre la carte de circuit imprimé et la lentille de sorte à conduire de la chaleur émise par la carte de circuit imprimé vers un espace entre la lentille et la glace. Ainsi, on peut empêcher la condensation sur la glace facilement sans besoin d'élément extérieur.  For this purpose, a first aspect of the invention relates to a vehicle lighting device comprising at least one light source arranged to emit light, a printed circuit board on which the light source is mounted, at least one arranged lens. for receiving the light emitted by the light source and projecting a light beam towards an ice-cream of the device, and means for fixing the lens on the printed circuit board, characterized in that the fixing means is arranged to present a connection between the printed circuit board and the lens so as to conduct heat from the printed circuit board to a space between the lens and the ice. Thus, it is possible to prevent condensation on the ice easily without the need for an external element.

De manière avantageuse, le moyen de fixation est une vis de fixation thermiquement conductrice. De cette manière, la liaison thermique est plus fiable grâce à la surface large de la tête de vis. Advantageously, the fixing means is a thermally conductive fixing screw. In this way, the thermal connection is more reliable thanks to the wide surface of the screw head.

Alternativement, le moyen de fixation est un clip thermiquement conducteur. Ainsi, le montage est simple.  Alternatively, the fastening means is a thermally conductive clip. Thus, the editing is simple.

Une réalisation particulièrement intéressante consiste en ce que la source de lumière est une diode électroluminescente (LED). De cette manière, le dispositif dispose d'un rendement énergétique amélioré.  A particularly interesting embodiment is that the light source is a light emitting diode (LED). In this way, the device has improved energy efficiency.

Avantageusement, le dispositif d'éclairage comprend en outre un masque agencé pour être fixé sur la carte de circuit imprimé de manière à recouvrir la carte de circuit imprimé. Ainsi, on peut davantage protéger le dispositif, voir à amplifier encore le phénomène de conduction thermique vers l'avant si ce masque est un conducteur thermique. Advantageously, the lighting device further comprises a mask arranged to be fixed on the printed circuit board so as to cover the printed circuit board. Thus, we can further protect the device, see to further amplify the phenomenon of thermal conduction forward if this mask is a thermal conductor.

De manière avantageuse, le masque présente des ouvertures agencées pour laisser passer la lumière. De cette manière, le masque n'est pas un obstacle pour la lumière.  Advantageously, the mask has openings arranged to let the light. In this way, the mask is not an obstacle to light.

Une réalisation particulièrement intéressante consiste en ce que la lentille est surmoulée sur la carte de circuit imprimé. Ainsi, le dispositif est plus robuste.  A particularly interesting embodiment is that the lens is overmolded on the printed circuit board. Thus, the device is more robust.

Avantageusement, la carte de circuit imprimé comprend une portion souple, pliable, affaiblie par attaque laser. De cette manière, la conception du dispositif est modulable.  Advantageously, the printed circuit board comprises a flexible portion, foldable, weakened by laser attack. In this way, the design of the device is flexible.

Un second aspect de l'invention est un projecteur de véhicule comprenant un dispositif d'éclairage selon le premier aspect de l'invention.  A second aspect of the invention is a vehicle headlamp comprising a lighting device according to the first aspect of the invention.

Un troisième aspect de l'invention est un véhicule comprenant un projecteur selon le second aspect de l'invention.  A third aspect of the invention is a vehicle comprising a headlamp according to the second aspect of the invention.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels : Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which:

- les figures 1 A et 1 B représentent un dispositif d'éclairage selon un mode de réalisation de la présente invention en vue de face et de profil, respectivement.  - Figures 1A and 1B show a lighting device according to an embodiment of the present invention in front view and profile, respectively.

Les figures représentent un dispositif d'éclairage de véhicule 1 selon la présente invention. Le dispositif d'éclairage 1 comprend au moins une source de lumière 2, de préférence une diode électroluminescente (LED), agencée pour émettre de la lumière, une carte de circuit imprimé 3 sur laquelle est montée la source de lumière 1 , au moins une lentille 4, par exemple une lentille de feu de croisement/route, agencée pour recevoir la lumière émise par la source de lumière 2 et projeter un faisceau lumineux vers une glace 6 du dispositif d'éclairage 1 , et un moyen de fixation 5 de la lentille 4 sur la carte de circuit imprimé 3. The figures show a vehicle lighting device 1 according to the present invention. The lighting device 1 comprises at least one light source 2, preferably a light-emitting diode (LED), arranged to emit light, a printed circuit board 3 on which the light source 1 is mounted, at least one lens 4, for example a cross / road light lens, arranged to receive the light emitted by the light source 2 and to project a light beam to an ice 6 of the lighting device 1, and a fixing means 5 of the lens 4 on the printed circuit board 3.

Le moyen de fixation 5 qui est, par exemple, une vis de fixation ou un clip métallique est agencé pour présenter une liaison thermique entre la carte de circuit imprimé 3 et la lentille 4 de sorte à conduire de la chaleur émise par la carte de circuit 3 imprimé vers un espace entre la lentille 4 et la glace 6.  The fixing means 5 which is, for example, a fixing screw or a metal clip is arranged to have a thermal connection between the printed circuit board 3 and the lens 4 so as to conduct heat emitted by the circuit board 3 printed to a space between lens 4 and ice 6.

Egalement, il est possible que la lentille 4 soit en outre surmoulée sur la carte de circuit imprimé 3.  Also, it is possible for the lens 4 to be further overmolded on the printed circuit board 3.

Bien que cela ne soit pas représenté sur les figures, le dispositif peut en outre comprendre un masque présentant des ouvertures agencées pour laisser passer la lumière et être fixé sur la carte de circuit imprimé 3 de manière à recouvrir la carte de circuit imprimé 3. Egalement, afin de gagner de l'espace, il est possible de diminuer la taille du PCB en pliant celui-ci. Pour cela, on réalise un affaiblissement d'une zone rigide du PCB en exécutant une attaque laser sur une partie de cuivre de celui-ci, cette zone devient alors pliable ce qui permet de diminuer la taille du PCB. Il est évidemment possible de réaliser plusieurs parties affaiblies sur un même PCB. On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées aux différents modes de réalisation de l'invention décrits dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. En particulier, il est fait référence aux différents types de source de lumière, aux nombre de moyen de fixation et aux matériaux utilisés, etc.  Although not shown in the figures, the device may further comprise a mask having apertures arranged to let the light through and be fixed on the printed circuit board 3 so as to cover the printed circuit board 3. Also in order to save space, it is possible to reduce the size of the PCB by folding it. For this, it achieves a weakening of a rigid area of the PCB by performing a laser attack on a portion of copper thereof, this area becomes foldable which allows to reduce the size of the PCB. It is obviously possible to make several weakened parts on the same PCB. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described in the present description without departing from the scope of the invention defined by the appended claims. In particular, reference is made to the different types of light sources, the number of fasteners and the materials used, etc.
