Description

La présente invention concerne de manière générale les dispositifs d'éclairage ou de signalisation, dont les sources lumineuses sont à incandescence, et que l'on désire changer par des sources lumineuses du type de diodes électroluminescentes.The present invention relates generally to lighting or lighting devices. signaling, whose light sources are incandescent, and which one wishes to change by light sources of the light-emitting diode type.

Une telle situation peut par exemple se rencontrer dans les dispositifs d'éclairage ou de signalisation de véhicules automobiles, des tels dispositifs d'éclairage ou de signalisation comportant des sources lumineuses à incandescence seules ou associées à des sources constituées de diodes électroluminescentes.Such a situation can for example be encountered in lighting or lighting devices. signaling of motor vehicles, such lighting or signaling devices comprising incandescent light sources alone or associated with sources made up of light-emitting diodes.

Les diodes électroluminescentes ont de manière connue une durée de vie beaucoup plus élevée que celle des sources à incandescence. L'utilisation de diodes électroluminescentes permet de profiter de leur faible encombrement pour réaliser des dispositifs d'éclairage ou de signalisation relativement compacts. De plus, le faible dégagement de chaleur provoqué par le fonctionnement des diodes électroluminescentes permet par exemple d'utiliser dans leur environnement immédiat des matières plastiques, alors que des lampes à incandescence ou à halogènes imposeraient dans les mêmes conditions l'utilisation de matériaux pouvant supporter des températures élevées. Il en résulte donc un encombrement et un coût réduits.Light-emitting diodes have, in known manner, a long service life higher than that of incandescent sources. The use of diodes light-emitting allows to take advantage of their small footprint to achieve relatively compact lighting or signaling devices. In addition, the low heat generation caused by the operation of light emitting diodes allows for example to use in their immediate environment plastics, whereas incandescent or halogen lamps would impose under the same conditions the use of materials capable of withstanding high temperatures. This therefore results in a reduced size and cost.

On peut alors désirer remplacer des sources à incandescence par des diodes électroluminescentes, mais il est alors nécessaire de modifier profondément la structure du dispositif d'éclairage ou de signalisation pour pouvoir le faire. De plus, les dispositifs d'éclairage ou de signalisation doivent émettre, selon la fonction d'éclairage ou de signalisation dans laquelle la source à incandescence est utilisée, un faisceau lumineux dont la photométrie est définie réglementairement. Le simple remplacement d'une source à incandescence par une diode électroluminescente aura alors pour résultat que le faisceau lumineux n'aura plus la photométrie réglementaire.We may then wish to replace incandescent sources with diodes electroluminescent, but it is then necessary to profoundly modify the structure of the lighting or signaling device to be able to do so. In addition, the devices lighting or signaling must emit, depending on the lighting or signaling in which the incandescent source is used, a light beam whose photometry is defined by law. Simply replacing a source at incandescent by a light emitting diode will then result in the beam light will no longer have regulatory photometry.

Il est d'autres cas où le dispositif d'éclairage ou de signalisation comporte à la fois des sources à incandescence et des diodes électroluminescentes pour assurer différentes fonctions. Par construction, il est alors nécessaire de prévoir dans ce dispositif d'éclairage ou de signalisation, deux circuits imprimés différents, l'un pour les sources à incandescence, l'autre pour les diodes électroluminescentes, de manière à ce que les faisceaux lumineux émis par ces sources différentes soient réglementaires.There are other cases where the lighting or signaling device includes both incandescent sources and light emitting diodes to perform different functions. By construction, it is then necessary to provide in this lighting device or signaling, two different printed circuits, one for incandescent sources, the other for light-emitting diodes, so that the light beams emitted by these different sources are regulatory.

La présente invention se place dans ce contexte et elle a pour but de proposer un module permettant d'utiliser dans un dispositif d'éclairage ou de signalisation une diode électroluminescente à la place d'une source à incandescence, sans avoir à remanier complètement l'architecture du dispositif d'éclairage ou de signalisation, et permettant également de réaliser un dispositif d'éclairage ou de signalisation comportant à la fois des sources à incandescence et des diodes électroluminescentes, qui ne comporte qu'un seul circuit imprimé pour assurer l'alimentation de des deux types de sources lumineuses.The present invention is placed in this context and it aims to provide a module for using a diode in a lighting or signaling device electroluminescent instead of an incandescent source, without having to rearrange completely the architecture of the lighting or signaling device, and allowing also to produce a lighting or signaling device comprising both incandescent sources and light emitting diodes, which has only one printed circuit to supply the two types of light sources.

La présente invention a donc pour objet un module de positionnement et d'alimentation d'une diode électroluminescente, le module comportant un boítier formant support pour au moins une diode électroluminescente et un connecteur d'alimentation électrique.The present invention therefore relates to a positioning module and for supplying a light-emitting diode, the module comprising a housing forming support for at least one light-emitting diode and a power connector electric.

Selon la présente invention, le connecteur a la forme et les dimensions du culot d'une lampe à incandescence, le boítier et le connecteur étant d'une seule pièce, et la diode électroluminescente étant montée sur un circuit imprimé.According to the present invention, the connector has the shape and dimensions of the base of a incandescent lamp, the housing and the connector being in one piece, and the diode electroluminescent being mounted on a printed circuit.

Sur les différentes Figures, les éléments identiques ou jouant le même rôle sont affectés des mêmes signes de référence.In the different Figures, identical elements or playing the same role are affected by the same reference signs.

On a représenté sur les Figures un module de positionnement et d'alimentation d'une diode électroluminescente, ce module étant désigné dans son ensemble par la référence 10. Le module comporte un boítier 12 formant support pour au moins une diode électroluminescente 14, deux telles diodes ayant été représentées sur la Figure 1. Les diodes 14 sont montées sur un circuit imprimé 16, dont le pourtour extérieur est complémentaire de la forme de la paroi intérieure 18 du boítier 12.The figures show a module for positioning and supplying a light emitting diode, this module being designated as a whole by the reference 10. The module includes a housing 12 forming a support for at least one light-emitting diode 14, two such diodes having been shown in FIG. 1. The diodes 14 are mounted on a printed circuit 16, the outer periphery of which complements the shape of the wall interior 18 of the housing 12.

Le boítier 12 est fermé par un couvercle 20, réalisé en un matériau transparent de manière à permettre le passage des rayons lumineux émis par la diode électroluminescente 14 selon une direction générale d'émission X.The housing 12 is closed by a cover 20, made of a transparent material of so as to allow the passage of the light rays emitted by the light-emitting diode 14 according to a general direction of emission X.

De manière à assurer le positionnement de la ou des diodes 14, le boítier comporte des butées 22 sur lesquelles vient en butée le circuit imprimé portant les diodes 14. Les butées 22 peuvent par exemple être obtenues par des épaulements 22 formés sur la paroi intérieure 18 du boítier 12. In order to ensure the positioning of the diode or diodes 14, the housing includes stops 22 on which the printed circuit carrying the diodes 14 abuts. The stops 22 can for example be obtained by shoulders 22 formed on the inner wall 18 of the case 12.

Le boítier 12 comporte également un connecteur d'alimentation électrique 24. De manière avantageuse, le boítier 12 et le connecteur 24 sont d'une seule pièce, et obtenus par exemple par moulage par injection d'une matière thermoplastique.The housing 12 also includes a power supply connector 24. From advantageously, the housing 12 and the connector 24 are in one piece, and obtained by example by injection molding of a thermoplastic material.

Conformément à la présente invention, le connecteur 24 a la forme et les dimensions du culot d'une lampe à incandescence. Dans le mode de réalisation représenté sur la Figure 1, le connecteur 24 est cylindrique, et comporte des excroissances 26 permettant son montage à baïonnette dans une douille conventionnelle, destinée à recevoir le culot d'une lampe à incandescence.According to the present invention, the connector 24 has the shape and the dimensions the base of an incandescent lamp. In the embodiment shown in Figure 1, the connector 24 is cylindrical, and includes protrusions 26 allowing its mounting at bayonet in a conventional socket, intended to receive the base of a lamp with incandescence.

De manière à assurer l'alimentation électrique de la ou des diodes, le module comporte des conducteurs électriques 28 et 30 entre le connecteur 24 et le circuit imprimé 16 portant la ou les diodes électroluminescentes. De tels conducteurs sont représentés sur les Figures 3 et 4, et sont plus particulièrement destinés à assurer un contact électrique central dans l'axe du connecteur cylindrique 24 et un contact électrique à la périphérie du connecteur 24.In order to ensure the electrical supply of the diode (s), the module comprises electrical conductors 28 and 30 between the connector 24 and the printed circuit 16 carrying the or light emitting diodes. Such conductors are shown in Figures 3 and 4, and are more particularly intended to ensure a central electrical contact in the axis of the cylindrical connector 24 and an electrical contact at the periphery of the connector 24.

Par exemple, le conducteur 28 peut comporter des pattes 32 pour un contact périphérique, ces pattes 32 passant par des ouvertures 34 formées dans le connecteur 24. Les pattes 32 peuvent être obtenues par pliage d'une languette 34, cette dernière pouvant se continuer par une partie 36 destinée à venir au contact du circuit imprimé 16 et lui être connectée, par exemple par soudure. Le conducteur 28 sera avantageusement réalisé en un matériau présentant une certaine élasticité, de manière à assurer un bon contact électrique entre les pattes 32 et les plots électriques contenus dans la douille recevant le connecteur 24.For example, the conductor 28 may have tabs 32 for contact peripheral, these tabs 32 passing through openings 34 formed in the connector 24. The tabs 32 can be obtained by folding a tongue 34, the latter possibly being continue with a part 36 intended to come into contact with the printed circuit 16 and be connected, for example by soldering. The conductor 28 will advantageously be made in one material with a certain elasticity, so as to ensure good electrical contact between the lugs 32 and the electrical studs contained in the socket receiving the connector 24.

De la même manière, le conducteur 30 pourra être réalisé sous la forme d'un pion cylindrique, et assurer un contact électrique central dans l'axe du connecteur cylindrique 24. Le conducteur 30 est formé avec une première extrémité 38 au centre du connecteur 24 assurant le contact électrique avec un plot électrique central contenu dans la douille recevant le connecteur 24, et avec une seconde extrémité 40 destinée à venir au contact du circuit imprimé 16 et lui être connectée, par exemple par soudure. In the same way, the conductor 30 can be made in the form of a pawn cylindrical, and ensure a central electrical contact in the axis of the cylindrical connector 24. The conductor 30 is formed with a first end 38 in the center of the connector 24 ensuring electrical contact with a central electrical stud contained in the receiving socket the connector 24, and with a second end 40 intended to come into contact with the circuit printed 16 and be connected to it, for example by soldering.

Les conducteurs 28 et 30 sont maintenus en place dans le connecteur 24 en étant séparés l'un de l'autre, le connecteur étant par exemple obtenu par surmoulage du matériau isolant constituant le boítier 12 et le connecteur 24 sur les conducteurs 28 et 30.The conductors 28 and 30 are held in place in the connector 24 while being separated from each other, the connector being for example obtained by overmolding of the material insulator constituting the housing 12 and the connector 24 on the conductors 28 and 30.

Pour obtenir le faisceau lumineux ayant la photométrie requise par la fonction d'éclairage ou de signalisation dont la ou les diodes électroluminescentes 14 sont la ou les sources lumineuses, on pourra avantageusement prévoir que le couvercle transparent 20 comporte des moyens de déviation des rayons lumineux émis par la ou les diodes électroluminescentes 14.To obtain the light beam with the photometry required by the function lighting or signaling device, the light-emitting diode or diodes 14 of which are light sources, it may advantageously be provided that the transparent cover 20 includes means for deflecting the light rays emitted by the diode or diodes electroluminescent 14.

De tels moyens de déviation peuvent par exemple comporter un premier élément 42, situé au voisinage de la ou des diodes 14, et apte à répartir la lumière émise par la ou les diodes électroluminescentes dans un plan XY essentiellement perpendiculaire à la direction générale d'émission X, de façon essentiellement homogène sur un deuxième élément 44, en forme générale de plaque et apte à redresser la lumière incidente sur lui sensiblement vers la direction générale d'émission X'-X, selon la fonction d'éclairage ou de signalisation concernée.Such deflection means can for example comprise a first element 42, located in the vicinity of the diode or diodes 14, and capable of distributing the light emitted by the one or more light-emitting diodes in an XY plane essentially perpendicular to the direction general emission X, essentially homogeneously on a second element 44, in general form of plate and able to straighten the light incident on it substantially towards the general direction of emission X'-X, depending on the lighting or signaling function concerned.

De tels moyens de déviation sont par exemple décrits dans le document FR-A-2 813 379, au nom de la Demanderesse.Such deflection means are for example described in document FR-A-2 813 379, in the name of the Claimant.

Pour faciliter le montage du couvercle 20 sur le boítier 12, on pourra prévoir que le couvercle transparent soit fixé sur le boítier par encliquetage. Le couvercle 20 pourra par exemple comporter des nervures 46, destinées à coopérer avec des sillons 48 formés dans la paroi intérieure 18 du boítier 12.To facilitate mounting of the cover 20 on the housing 12, provision may be made for the transparent cover is fixed on the housing by snap-fastening. The cover 20 may by example include ribs 46, intended to cooperate with grooves 48 formed in the inner wall 18 of the housing 12.

Pour assembler le module de la présente invention, il suffit de disposer le circuit imprimé 16 sur les butées 22, puis de souder les conducteurs 28 et 30 sur ce circuit imprimé. Le couvercle 20 peut alors être fixé, par encliquetage, sur le boítier 12.To assemble the module of the present invention, it suffices to arrange the circuit printed 16 on the stops 22, then solder the conductors 28 and 30 on this printed circuit. The cover 20 can then be fixed, by snap-fastening, to the housing 12.

Le module 10 est alors prêt à être utilisé. Comme on l'a représenté schématiquement en coupe sur la Figure 2, il suffit d'engager le connecteur 24 dans la douille 50 prévue dans le dispositif d'éclairage ou de signalisation à équiper. Cette douille 50 était par exemple prévue pour recevoir le culot d'une lampe à incandescence, coopérant avec un réflecteur 52 pour former un faisceau d'éclairage ou de signalisation. De la même manière que pour cette lampe, on fixe le module dans la douille 50 par une rotation, de sorte que le module 10 est monté à baïonnette dans la douille 50. Le connecteur 24 sert ainsi à la fois au positionnement du module dans le dispositif d'éclairage ou de signalisation, et à son alimentation électrique.The module 10 is then ready to be used. As shown schematically in section in Figure 2, simply engage the connector 24 in the socket 50 provided in the lighting or signaling device to be fitted. This socket 50 was for example provided to receive the base of an incandescent lamp, cooperating with a reflector 52 for form a lighting or signaling beam. In the same way as for this lamp, the module is fixed in the socket 50 by a rotation, so that the module 10 is mounted at bayonet in the socket 50. The connector 24 is thus used both for positioning the module in the lighting or signaling device, and its power supply.

On a donc bien réalisé selon la présente invention un module permettant d'utiliser dans un dispositif d'éclairage ou de signalisation une diode électroluminescente à la place d'une source à incandescence, sans avoir à remanier complètement l'architecture du dispositif d'éclairage ou de signalisation, et permettant également de réaliser un dispositif d'éclairage ou de signalisation comportant à la fois des sources à incandescence et des diodes électroluminescentes, qui ne comporte qu'un seul circuit imprimé pour assurer l'alimentation de des deux types de sources lumineuses, le module comportant lui-même le circuit imprimé pour l'alimentation de la ou des diodes électroluminescentes qu'il contient.A module has therefore been produced according to the present invention which makes it possible to use in a lighting or signaling device a light-emitting diode in place of a incandescent source, without having to completely overhaul the architecture of the device lighting or signaling, and also making it possible to produce a lighting or signaling system comprising both incandescent sources and diodes electroluminescent, which has only one printed circuit to supply power of two types of light sources, the module itself comprising the printed circuit for the supply of the light-emitting diode (s) it contains.

Bien entendu, la présente invention n'est pas limitée aux modes de réalisation qui ont été décrits, mais l'homme du métier pourra au contraire lui apporter de nombreuses modifications qui rentrent dans son cadre. C'est ainsi par exemple qu'on pourra prévoir un montage du module par vissage, au lieu du montage à baïonnette qui a été décrit.Of course, the present invention is not limited to the embodiments which have have been described, but those skilled in the art may on the contrary provide it with numerous modifications that fall within its scope. This is how, for example, we can plan a mounting of the module by screwing, instead of the bayonet mounting which has been described.
