Description

Dispositif électrique pour véhicule automobile, notamment pour former un feu d'éclairage et/ou de signalisation L'invention concerne notamment un dispositif électrique pour véhicule automobile. On connaît par la demande de brevet FR 2 844 579 un dispositif d'éclairage ou de signalisation dont les sources lumineuses sont, au choix, à incandescence ou à diodes électroluminescentes (LEDs). Cette demande de brevet FR 2 844 579 décrit en particulier des diodes fixées sur une carte de circuit imprimé, l'ensemble étant placé dans un boîtier. Ce boîtier comprend une partie de connexion réalisée par moulage par injection et pouvant être montée dans un porte- lampe destiné à une lampe à incandescence. Dans ce type de dispositif connu, il est nécessaire de s'assurer de l'alignement très précis des différents éléments du montage. L'invention propose notamment un nouveau dispositif électrique permettant de s'affranchir des limitations précitées. L'invention a ainsi pour objet un dispositif électrique pour véhicule automobile, notamment pour former un feu d'éclairage et/ou de signalisation, 20 comportant : - au moins un composant électrique, pouvant éventuellement être un composant électronique, ce composant comportant de préférence une source lumineuse et étant par exemple une diode électroluminescente, - au moins un connecteur agencé pour permettre l'alimentation électrique du composant électrique, ce connecteur étant compatible avec une interface porte- lampe/ lampe, - un élément de raccordement électrique entre le composant électrique et le connecteur, cet élément de raccordement étant de préférence flexible. 25 30 On entend par 'connecteur compatible avec une interface porte- lampe/ lampe' un connecteur agencé pour pourvoir être monté dans un emplacement du porte- lampe prévu pour recevoir indifféremment un culot d'une lampe, notamment d'une lampe à incandescence, ou le connecteur du dispositif selon l'invention. Ainsi, par exemple, il est possible, grâce à l'invention, de remplacer, dans des éclairages existants utilisant une ou plusieurs lampes à incandescence, cette ou ces lampes par une ou plusieurs diodes électroluminescentes, sans avoir à modifier le porte- lampe. Electrical device for a motor vehicle, especially for forming a lighting and / or signaling light The invention particularly relates to an electric device for a motor vehicle. The patent application FR 2 844 579 discloses a lighting or signaling device whose light sources are, optionally, incandescent or light-emitting diodes (LEDs). This patent application FR 2 844 579 describes in particular diodes fixed on a printed circuit board, the assembly being placed in a housing. This housing comprises a connection portion made by injection molding and can be mounted in a lamp holder for an incandescent lamp. In this type of known device, it is necessary to ensure the very precise alignment of the various elements of the assembly. The invention proposes in particular a new electrical device to overcome the aforementioned limitations. The subject of the invention is thus an electrical device for a motor vehicle, in particular for forming a lighting and / or signaling light, comprising: at least one electrical component, which may optionally be an electronic component, this component preferably comprising a light source and being for example a light-emitting diode, - at least one connector arranged to allow the electrical power supply of the electrical component, this connector being compatible with a lamp / lamp holder interface, - an electrical connection element between the electrical component and the connector, this connecting element being preferably flexible. The term "connector compatible with a lamp-holder / lamp interface" means a connector arranged to be mounted in a location of the lamp holder provided to receive indifferently a base of a lamp, in particular of an incandescent lamp, or the connector of the device according to the invention. Thus, for example, it is possible, thanks to the invention, to replace, in existing lighting using one or more incandescent lamps, this or these lamps with one or more light-emitting diodes, without having to modify the lamp holder.

Ceci permet par exemple de concevoir de nouveaux systèmes d'éclairage ou de signalisation, par exemple utilisant des LEDs, sans investissements importants, en profitant de portes-lampe existants. De plus, à la différence du dispositif décrit dans la demande de brevet FR 2 844 579, dans la présente invention, du fait de l'élément de raccordement flexible, il n'est pas nécessaire d'avoir un alignement entre le porte- lampe et le composant électrique. L'invention peut ainsi permettre une plus grande liberté pour placer le composant électrique par rapport au porte-lampe. L'invention peut également être adaptée au logement de tout type d'ampoule. This allows for example to design new lighting or signaling systems, for example using LEDs, without significant investments, taking advantage of existing lamp holders. In addition, unlike the device described in the patent application FR 2 844 579, in the present invention, because of the flexible connection element, it is not necessary to have an alignment between the lamp holder and the electrical component. The invention can thus allow greater freedom to place the electrical component relative to the lamp holder. The invention can also be adapted to accommodate any type of bulb.

De plus l'invention permet de s'affranchir d'un type de connexion standard plus complexe. Par ailleurs, l'invention permet d'éviter une connexion avec le faisceau client. De préférence, le connecteur présente une forme et des dimensions sensiblement identiques à celles du culot de la lampe à incandescence. In addition, the invention makes it possible to dispense with a more complex type of standard connection. Moreover, the invention makes it possible to avoid a connection with the client beam. Preferably, the connector has a shape and dimensions substantially identical to those of the base of the incandescent lamp.

Le connecteur peut avantageusement être réalisé comme un culot d'une lampe à incandescence. Dans un exemple de mise en oeuvre de l'invention, le connecteur présente une forme sensiblement cylindrique, notamment de révolution. Le cas échéant, le connecteur peut comporter au moins un ergot de positionnement. The connector can advantageously be made as a base of an incandescent lamp. In an exemplary implementation of the invention, the connector has a substantially cylindrical shape, in particular of revolution. If necessary, the connector may comprise at least one positioning pin.

Si on le souhaite, l'élément de raccordement flexible comporte au moins l'un des éléments suivants : un fil électrique, une nappes de fils électriques accolés, un circuit imprimé souple. Un circuit imprimé souple comprend par exemple une feuille souple portant des pistes conductrices et des composants électroniques. Dans un exemple de mise en oeuvre de l'invention, le dispositif comporte un circuit imprimé rigide monté sur le connecteur, et l'élément de raccordement flexible est relié à ce circuit imprimé rigide. Le circuit imprimé rigide et/ou le circuit imprimé souple sont avantageusement 10 agencés pour commander le composant électrique. De préférence, le composant électrique comporte une diode électroluminescente, notamment fixée sur un support rigide tel qu'une carte de circuit imprimé. Ce support rigide porte, le cas échéant, une pluralité de LEDs. Le dispositif peut, si on le souhaite, comporter une pluralité de diodes 15 électroluminescentes reliées entre elles par des fils électriques. Par exemple le ou les diodes électroluminescentes sont choisies pour former un feu d'éclairage ou de signalisation de véhicule automobile. Dans un autre exemple de mise en oeuvre de l'invention, le composant électrique comporte un ventilateur. 20 L'invention a également pour objet un ensemble comportant : - un dispositif tel que défini ci-dessus, - un porte- lampe comportant un réceptacle pour recevoir indifféremment le connecteur dudit dispositif ou un culot de lampe. L'ensemble précité peut former par exemple un feu d'éclairage ou un feu de 25 signalisation. Le cas échéant, le porte- lampe comporte une lame de contact électrique dans le fond du réceptacle. Si on le souhaite, le réceptacle du porte- lampe pour recevoir le connecteur est formé dans une douille du porte- lampe. If desired, the flexible connection element comprises at least one of the following elements: an electrical wire, a layer of electrical wires contiguous, a flexible printed circuit. A flexible printed circuit comprises for example a flexible sheet carrying conductive tracks and electronic components. In an exemplary implementation of the invention, the device comprises a rigid printed circuit mounted on the connector, and the flexible connecting element is connected to this rigid printed circuit. The rigid printed circuit and / or the flexible printed circuit are advantageously arranged to control the electrical component. Preferably, the electrical component comprises a light-emitting diode, in particular fixed on a rigid support such as a printed circuit board. This rigid support carries, if necessary, a plurality of LEDs. The device may, if desired, have a plurality of light-emitting diodes connected together by electrical wires. For example, the light emitting diode (s) are chosen to form a lighting or signaling light of a motor vehicle. In another embodiment of the invention, the electrical component comprises a fan. The invention also relates to an assembly comprising: - a device as defined above, - a lamp holder having a receptacle for receiving indifferently the connector of said device or a lamp base. The aforesaid assembly may for example form a lighting or signaling light. Where appropriate, the lamp holder has an electrical contact blade in the bottom of the receptacle. If desired, the receptacle of the lamp holder for receiving the connector is formed in a socket of the lamp holder.

Dans un exemple de mise en oeuvre de l'invention, l'ensemble précité comporte une lampe à incandescence pourvue d'un culot pouvant être monté, le cas échéant, dans le réceptacle du porte- lampe. L'invention a encore pour objet un procédé pour fabriquer un feu d'éclairage ou de signalisation, à l'aide d'un dispositif tel défini ci-dessus, le procédé comportant l'étape suivante : - monter le connecteur dudit dispositif sur un porte- lampe prévu pour recevoir indifféremment une lampe à incandescence ou ce connecteur. In an exemplary implementation of the invention, the aforementioned assembly comprises an incandescent lamp provided with a base which can be mounted, if necessary, in the receptacle of the lamp holder. The invention also relates to a method for manufacturing a lighting or signaling light, using a device as defined above, the method comprising the following step: - mount the connector of said device on a lamp holder provided to receive either an incandescent lamp or this connector.

On a représenté sur la figure 1 un porte- lampe 1 et une lampe à incandescence 2 montée sur le porte- lampe 1. Ces éléments font partie par exemple d'un projecteur ou un feu 3 de véhicule automobile, par exemple, pour l'arrière du véhicule, un feu stop, une lanterne, un clignotant, un anti-brouillard, un feu de recul, et pour l'avant, un clignotant, un éclairage de jour ou DRL (Day Running Light en anglais), une lampe ville. FIG. 1 shows a lamp holder 1 and an incandescent lamp 2 mounted on the lamp holder 1. These elements are part of, for example, a searchlight or a motor vehicle light 3, for example, for the rear of the vehicle, a brake light, a lantern, a flashing light, an anti-fog, a reversing light, and for the front, a flashing light, a daytime running light or DRL (Day Running Light in English), a city lamp .

Ce projecteur 3 comprend en outre un réflecteur 4 pourvu d'un orifice 5 pour le passage de la lampe 2, et également une glace 6 placée à l'avant de la lampe 2. La lampe 2 comprend, de manière classique, un culot 10 métallique de forme généralement cylindrique. La lampe 2 peut par exemple être du type P21W, P21/5W, PY21/W, R5W, W5W... Le porte- lampe 1 comporte un réceptacle 11 pour recevoir le culot 10 de la lampe à incandescence 2. This projector 3 further comprises a reflector 4 provided with an orifice 5 for the passage of the lamp 2, and also a lens 6 placed at the front of the lamp 2. The lamp 2 comprises, in a conventional manner, a base 10 metal of generally cylindrical shape. The lamp 2 may for example be of the type P21W, P21 / 5W, PY21 / W, R5W, W5W. The lamp holder 1 comprises a receptacle 11 for receiving the base 10 of the incandescent lamp 2.

Ce réceptacle 1 est formé notamment par une bague de maintien 12 pourvue d'une collerette 13. Le réceptacle 11 est ouvert sur le fond et le porte- lampe 1 comprend une lame de contact 15 en métal, élastiquement déformable, pour venir d'appuyer sur le fond du culot 10 de la lampe à incandescence 2, lorsque celle-ci est en montée sur le porte- lampe 1. Dans le présent exemple, le réceptacle 11 du porte- lampe forme une interface porte- lampe/ lampe au sens de la présente invention. Il est possible de remplacer la lampe à incandescence 2 par un dispositif électrique 20. This receptacle 1 is formed in particular by a retaining ring 12 provided with a flange 13. The receptacle 11 is open on the bottom and the lamp holder 1 comprises a metal contact blade 15, elastically deformable, to come to support on the bottom of the base 10 of the incandescent lamp 2, when it is mounted on the lamp holder 1.
