Description

L'invention concerne les domaines techniques de l'éclairage et de la signalisation des véhicules automobiles, et s'intéresse en particulier aux modules lumineux comportant des diodes électroluminescentes organiques connues également sous l'acronyme anglosaxon OLED (Organic Light Emiting Diode).The invention relates to the technical fields of lighting and signaling of motor vehicles, and is particularly interested in light modules comprising organic light-emitting diodes also known by the acronym Anglosaxon OLED (Organic Light Emitting Diode).

Les progrès techniques récents, qui tendent à prolonger la durée de vie et à diminuer les coûts de fabrication des diodes électroluminescentes organiques, ont avivé l'intérêt des stylistes et des concepteurs de véhicule pour ces sources lumineuses. Elles permettent de produire des effets lumineux difficiles à obtenir avec des sources lumineuses telles que des ampoules à filament ou encore des ampoules LED. Ces diodes électroluminescentes organiques offrent également l'avantage d'être peu consommatrices d'énergie.Recent technological advances, which tend to extend the life span and lower the manufacturing costs of organic light-emitting diodes, have increased the interest of stylists and vehicle designers in these light sources. They make it possible to produce luminous effects that are difficult to obtain with light sources such as filament bulbs or LED bulbs. These organic light-emitting diodes also have the advantage of being low energy consumers.

Une diode électroluminescente organique se présente généralement sous la forme d'une anode et d'une cathode entre lesquelles sont encapsulées une ou plusieurs couches de matière organique contenant par exemple des matériaux tels que des polyanilines ou des polyfluorènes sont disposées.An organic light-emitting diode is generally in the form of an anode and a cathode between which are encapsulated one or more layers of organic material containing for example materials such as polyanilines or polyfluorenes are disposed.

En vue de l'intégration dans des modules lumineux de ce type de diode, les systèmes existants utilisent des supports comprenant un compartiment, une partie de raccordement de la diode étant insérée dans ce compartiment puis bloquée dans le support au moyen d'une pièce de fixation supplémentaire telle qu'une barrette venant serrer la partie de raccordement.For the integration into light modules of this type of diode, the existing systems use supports comprising a compartment, a connecting portion of the diode being inserted into this compartment and then locked in the support by means of a piece of additional fastening such as a bar clamping the connection portion.

Ce type d'intégration nécessite donc une pièce externe au support, ce qui implique tant un coût supplémentaire qu'une étape additionnelle lors du procédé de montage de la diode dans le module.This type of integration therefore requires a part external to the support, which involves both an additional cost and an additional step during the method of mounting the diode in the module.

En outre, le mode de fixation retenu dans les solutions connues repose sur un maintien de la diode dans le support par serrage, c'est-à-dire par frottement de la pièce externe contre la diode. Or, dans le domaine automobile, les modules lumineux sont soumis à des perturbations telles que des vibrations ou des chocs. La pièce externe peut donc également être soumise à ces perturbations, qui viendraient donc gêner la fixation. Par conséquent, le maintien en position de la diode dans le module lumineux n'est pas garanti, ce qui peut affecter l'esthétisme du module, voire le fonctionnement du module lorsque la diode est associée à des éléments optiques.In addition, the method of attachment retained in the known solutions is based on maintaining the diode in the support by clamping, that is to say by friction of the outer part against the diode. However, in the automotive field, the light modules are subject to disturbances such as vibrations or shocks. The outer part can therefore also be subjected to these disturbances, which would therefore interfere with the fixing. Therefore, the retention in position of the diode in the light module is not guaranteed, which can affect the aesthetics of the module, or even the operation of the module when the diode is associated with optical elements.

Il existe donc un besoin pour pallier l'ensemble de ces impératifs techniques, économiques et esthétiques.There is therefore a need to overcome all these technical, economic and aesthetic imperatives.

L'invention a pour objet d'apporter une solution technique à ce besoin.The invention aims to provide a technical solution to this need.

Le module lumineux selon l'invention comprend un support comportant au moins un orifice de montage et au moins une diode électroluminescente organique comportant une première partie émettrice de lumière et une partie de montage destinée à être insérée dans l'orifice de montage.The light module according to the invention comprises a support having at least one mounting hole and at least one organic light-emitting diode having a first light-emitting portion and a mounting portion for insertion into the mounting hole.

Ce module se caractérise en ce que la diode électroluminescente organique comporte au moins un premier moyen de fixation de la diode destiné à coopérer avec au moins un premier moyen de fixation complémentaire du support, ledit moyen de fixation de la diode étant disposé sur au moins une paroi de la partie de montage.This module is characterized in that the organic electroluminescent diode comprises at least a first diode fixing means intended to cooperate with at least one first means of complementary attachment of the support, said diode fixing means being arranged on at least one wall of the mounting part.

Par conséquent, dans le module selon l'invention, c'est la diode électroluminescente elle-même qui comporte le moyen de fixation au support, ce qui permet de s'affranchir d'une pièce externe. De plus, la diode étant directement fixée au support, on diminue le risque que d'éventuels vibrations et chocs transmis du module au support viennent perturber la fixation.Consequently, in the module according to the invention, it is the light-emitting diode itself which comprises the means of attachment to the support, which makes it possible to dispense with an external part. In addition, the diode being directly attached to the support, it reduces the risk that any vibrations and shocks transmitted from the module to the support disrupt the fixing.

Si on le souhaite, le support peut comporter un corps sur lequel est montée une embase creuse formant l'orifice. Dans ce cas, la partie de montage de la diode électroluminescente et l'embase du support peuvent former une paire culot/douille standard, c'est-à-dire dont les caractéristiques respectent une norme standardisée. Il est ainsi possible de donner à la première partie émettrice de lumière une forme libre. Si on le souhaite, le corps peut être comporter un trou en vis-à-vis de l'embase, de sorte à ce que l'orifice traverse la totalité du support. Selon une variante de l'invention, le support peut comporter deux embases, notamment montées de part et d'autre du corps, chaque embase formant un orifice de montage d'une diode électroluminescente d'un module selon l'invention.If desired, the support may comprise a body on which is mounted a hollow base forming the orifice. In this case, the mounting portion of the light emitting diode and the base of the support can form a standard pair of cap / socket, that is to say whose characteristics comply with a standardized standard. It is thus possible to give the first light-emitting part a free form. If desired, the body may have a hole opposite the base, so that the orifice passes through the entire support. According to a variant of the invention, the support may comprise two bases, in particular mounted on either side of the body, each base forming a mounting orifice of a light-emitting diode of a module according to the invention.

On entend par partie de montage une partie de la diode électroluminescente dépourvu de rôle optique, c'est-à-dire n'émettant aucune lumière. De préférence, la première partie émettrice de lumière présente une aire supérieure à celle de la partie de montage.By mounting part is meant a part of the light-emitting diode devoid of optical role, that is to say, emitting no light. Preferably, the first light-emitting portion has an area greater than that of the mounting portion.

Avantageusement, la partie émettrice de la diode électroluminescente organique est délimitée par deux parois en vis-à-vis, entre lesquelles est disposée au moins une couche de matériau organique apte à émettre de la lumière lorsque la diode est alimentée électriquement. Dans ce cas, l'une au moins de ces parois, voire chaque paroi, est apte à laisser passer de la lumière. Par exemple, ladite paroi apte à laisser passer de la lumière est réalisée en un matériau transparent ou translucide, notamment du verre ou du plastique. De préférence, ladite paroi apte à laisser passer de la lumière est plane au moins au niveau de la première partie émettrice de lumière. Si on le souhaite, ladite couche de matériau organique s'étend sur une surface inférieure ou égale à celle de ladite paroi apte à laisser passer de la lumière. Par exemple, la totalité de ladite couche de matériau organique peut être encadré par la paroi apte à laisser passer de la lumière. De préférence, les parois forment un boîtier étanche enfermant ladite couche de matériau organique.Advantageously, the emitting part of the organic light-emitting diode is delimited by two walls facing each other, between which is disposed at least one layer of organic material capable of emitting light when the diode is electrically powered. In this case, at least one of these walls, or even each wall, is able to let in light. For example, said wall capable of passing light is made of a transparent or translucent material, in particular glass or plastic. Preferably, said light-passable wall is planar at least at the first light-emitting portion. If desired, said layer of organic material extends over a surface less than or equal to that of said wall capable of allowing light to pass. For example, all of said layer of organic material may be framed by the wall capable of passing light. Preferably, the walls form a sealed casing enclosing said layer of organic material.

Dans un mode de réalisation de l'invention, au moins une première paroi des deux parois délimitant la partie émettrice s'étend depuis une extrémité supérieure de la diode électroluminescente organique jusqu'à une extrémité inférieure de la diode électroluminescente, de sorte à former également ladite paroi de la partie de montage. Le cas échéant, ladite première paroi et la paroi de la partie de montage forment une seule pièce, par exemple venue de matière. En variante, la paroi de la partie de montage peut être surmoulée à ladite première paroi.In one embodiment of the invention, at least a first wall of the two walls defining the emitter portion extends from an upper end of the organic light-emitting diode to a lower end of the light-emitting diode, so as to also form said wall of the mounting part. Where appropriate, said first wall and the wall of the mounting part form a single piece, for example material. Alternatively, the wall of the mounting portion may be overmoulded to said first wall.

Avantageusement, le premier moyen de fixation de la diode est formé par une déformation d'une première surface de ladite paroi de la partie de montage. Par exemple, la première surface de la paroi de la partie de montage peut être généralement plane, le premier moyen de fixation de la diode étant un relief de cette première surface.Advantageously, the first fixing means of the diode is formed by deformation of a first surface of said wall of the mounting part. For example, the first surface of the wall of the mounting portion may be generally planar, the first fixing means of the diode being a relief of this first surface.

De préférence, l'un des premiers moyens de fixation de la diode et du support est apte à se déformer élastiquement, l'autre des premiers moyens de la fixation de la diode et du support étant rigide.Preferably, one of the first means for fixing the diode and the support is able to deform elastically, the other of the first means of fixing the diode and the support being rigid.

Selon un exemple de réalisation de l'invention, ladite déformation peut former un moyen d'encliquetage male de la partie de montage, le moyen complémentaire de fixation du support formant un moyen d'encliquetage femelle. Avantageusement, le premier moyen de fixation de la diode est formé par une excroissance, par exemple souple, de la première surface faisant saillie de ladite paroi de la partie de montage. L'excroissance peut être réalisée par un ajout de matière à la première surface, de sorte par exemple à modifier localement l'épaisseur de ladite paroi de la partie de montage au niveau dudit premier moyen de fixation. En variante, le premier moyen de fixation de la diode est formé par une ondulation de ladite paroi de la partie de montage. Dans ce cas, l'épaisseur de la paroi peut rester globalement constante le long de la partie de montage. Si on le souhaite, l'excroissance ou l'ondulation peut former un ressaut suivi d'une pente douce vers l'extrémité inférieure de la partie de montage. De manière non limitative, le premier moyen complémentaire de fixation du support peut être dans ce cas formé par un crochet, par exemple rigide, s'étendant dans l'orifice. Par exemple, ledit crochet peut s'étendre depuis un bord de l'orifice. En variante, ledit crochet peut comprendre une collerette s'étendant sur une surface interne de l'orifice.According to an exemplary embodiment of the invention, said deformation can form a male snap-fitting means of the mounting part, the complementary means for fixing the support forming a female latching means. Advantageously, the first fixing means of the diode is formed by a protrusion, for example flexible, of the first surface projecting from said wall of the mounting part. The protrusion can be achieved by adding material to the first surface, so for example locally to modify the thickness of said wall of the mounting portion at said level. first fixing means. Alternatively, the first diode attachment means is formed by a ripple of said wall of the mounting portion. In this case, the thickness of the wall can remain generally constant along the mounting portion. If desired, the protuberance or ripple may form a projection followed by a gentle slope toward the lower end of the mounting portion. In a nonlimiting manner, the first complementary means for fixing the support may in this case be formed by a hook, for example a rigid hook, extending into the orifice. For example, said hook may extend from an edge of the orifice. Alternatively, said hook may comprise a collar extending on an inner surface of the orifice.

Selon un autre exemple de réalisation de l'invention, ladite déformation forme un moyen d'encliquetage femelle de la partie de montage et le moyen complémentaire de fixation du support forme un moyen d'encliquetage male. Le cas échéant, le premier moyen de fixation de la diode peut être formé par un renfoncement de ladite paroi de la partie de montage. Par exemple, le renfoncement peut être réalisé par un retrait de matière de ladite paroi de la partie de montage. En variante, le renfoncement peut être formé par un trou traversant la partie de montage. De manière non limitative, le premier moyen complémentaire de fixation du support peut être dans ce cas formé par une languette souple s'étendant dans l'orifice. En variante, il peut s'agir d'une collerette souple ou d'un crochet souple.According to another embodiment of the invention, said deformation forms a female latching means of the mounting portion and the complementary means for fixing the support forms a male latching means. Where appropriate, the first diode attachment means may be formed by a recess in said wall of the mounting portion. For example, the recess may be made by removing material from said wall of the mounting portion. Alternatively, the recess may be formed by a hole passing through the mounting portion. In a nonlimiting manner, the first complementary means for fixing the support may in this case be formed by a flexible tongue extending into the orifice. Alternatively, it may be a flexible collar or a flexible hook.

Selon encore un autre exemple de réalisation, le premier moyen de fixation de la diode peut être formé par un renfoncement suivi d'une excroissance.According to yet another embodiment, the first means of fixing the diode may be formed by a recess followed by an outgrowth.

Avantageusement, la diode électroluminescente organique comporte un deuxième moyen de fixation destiné à coopérer avec un deuxième moyen de fixation complémentaire du support.Advantageously, the organic electroluminescent diode comprises a second fixing means intended to cooperate with a second means of complementary attachment of the support.

Dans un mode de réalisation de l'invention, la deuxième des deux parois délimitant la partie émettrice s'étend depuis une extrémité supérieure de la diode électroluminescente organique jusqu'à une extrémité supérieure de la partie de montage. En d'autres termes, la partie de montage peut être formée uniquement par ladite première paroi de la partie émettrice. Dans ce cas, l'autre paroi de la partie émettrice est rapportée sur ladite première paroi uniquement au niveau de la partie émettrice. Le cas échéant, ledit deuxième moyen de fixation de la diode est disposé sur ladite paroi de la partie de montage. Par exemple, le deuxième moyen de fixation de la diode est formé par une déformation d'une deuxième surface de ladite paroi de la partie de montage opposée à la première surface.In one embodiment of the invention, the second of the two walls defining the transmitting portion extends from an upper end of the organic light-emitting diode to an upper end of the mounting portion. In other words, the mounting part can be formed solely by said first wall of the emitting part. In this case, the other wall of the emitting part is attached to said first wall only at the emitting part. Where appropriate, said second diode attachment means is disposed on said wall of the mounting portion. For example, the second diode attachment means is formed by a deformation of a second surface of said wall of the mounting portion opposite the first surface.

Si on le souhaite, ladite paroi de la partie de montage présente une surépaisseur au niveau de la partie de montage, , notamment sur toute la longueur de la partie de montage. On améliore ainsi la tenue mécanique de la diode électroluminescente organique sur son support.If desired, said wall of the mounting portion has an extra thickness at the mounting portion, particularly along the entire length of the mounting portion. This improves the mechanical strength of the organic light-emitting diode on its support.

De préférence, la diode électroluminescente comporte au moins une piste électrique destiné à l'alimentation électrique de la diode, cette piste électrique étant disposé sur ladite paroi de la partie de montage. Le cas échéant, le support comporte un connecteur électrique destiné à coopérer avec ladite piste électrique. Le connecteur peut par exemple être une lame à ressort métallique disposé dans l'orifice.Preferably, the light-emitting diode comprises at least one electrical track intended for the electrical power supply of the diode, this electrical track being disposed on said wall of the mounting part. Where appropriate, the support comprises an electrical connector intended to cooperate with said electrical track. The connector may for example be a metal spring blade disposed in the orifice.

Dans un autre mode de réalisation de l'invention, la deuxième des deux parois délimitant la partie émettrice s'étend depuis une extrémité supérieure de la diode électroluminescente organique et au delà d'une extrémité supérieure de la partie de montage, de sorte à former une autre paroi de la partie de montage. Si on le souhaite, la deuxième paroi de la partie émettrice s'étend jusqu'à ladite extrémité inférieure de la diode. En variante, la deuxième paroi de la partie émettrice s'étend entre les extrémités inférieure de la diode et supérieure de la partie de montage. On libère ainsi un espace en dessous de ladite deuxième paroi de la partie émettrice, par exemple pour disposer une piste électrique d'alimentation. Le cas échéant, ledit deuxième moyen de fixation de la diode est disposé sur ladite autre paroi de la partie de montage. Par exemple, le deuxième moyen de fixation de la diode peut être formé par une déformation d'une surface de ladite autre paroi de la partie de montage, opposée à la première surface de ladite paroi de la partie de montage. Avantageusment, la position du deuxième moyen de fixation de la diode sur ladite autre paroi de la partie de montage peut être décalée par rapport à la position du premier moyen de fixation de la diode sur ladite paroi de la partie de montage. Il est ainsi possible de réaliser une fonction de détrompage du montage de la diode électroluminescente organique sur son support.In another embodiment of the invention, the second of the two walls defining the emitter portion extends from an upper end of the organic light-emitting diode and beyond an upper end of the mounting portion, so as to form another wall of the mounting part. If desired, the second wall of the emitter portion extends to said lower end of the diode. Alternatively, the second wall of the transmitting portion extends between the lower ends of the diode and upper of the mounting portion. This releases a space below said second wall of the emitting part, for example to have an electric supply track. Where appropriate, said second diode attachment means is disposed on said other wall of the mounting portion. For example, the second diode attachment means may be formed by deforming a surface of said other wall of the mounting portion opposite the first surface of said wall of the mounting portion. Advantageously, the position of the second diode attachment means on said other wall of the mounting portion may be offset from the position of the first diode attachment means on said wall of the mounting portion. It is thus possible to perform a keying function of the mounting of the organic light-emitting diode on its support.

L'invention a également pour objet une diode électroluminescente organique pour un module lumineux selon l'invention, la diode électroluminescente organique comportant une première partie émettrice de lumière et une partie de montage destinée à être insérée dans un orifice de montage, caractérisé en ce que la diode comporte au moins un premier moyen de fixation de la diode destiné à coopérer avec un premier moyen de fixation complémentaire dudit support, ledit moyen de fixation de la diode étant disposé sur au moins une paroi de la partie de montageThe subject of the invention is also an organic light-emitting diode for a light module according to the invention, the organic light-emitting diode comprising a first light-emitting part and a mounting part intended to be inserted into a mounting hole, characterized in that the diode comprises at least a first means for fixing the diode intended to cooperate with a first complementary fixing means of said support, said diode fixing means being disposed on at least one wall of the mounting part

L'invention sera mieux comprise à la lecture des figures annexées, qui sont fournies à titre d'exemples et ne présentent aucun caractère limitatif, dans lesquelles :

  • Les figures 1 et 2 représente, respectivement selon une vue en perspective et selon une vue en coupe, une diode électroluminescente organique et un module lumineux intégrant ladite diode électroluminescente organique selon un premier mode de réalisation de l'invention.
  • La figure 3 représente, en coupe, un module lumineux selon un deuxième mode de réalisation de l'invention.
  • La figure 4 représente, en coupe, un module lumineux selon un troisième mode de réalisation de l'invention.
The invention will be better understood on reading the appended figures, which are provided by way of examples and are in no way limiting, in which:
  • The Figures 1 and 2 represents, respectively in a perspective view and in a sectional view, an organic light-emitting diode and a light module incorporating said organic light-emitting diode according to a first embodiment of the invention.
  • The figure 3 represents, in section, a light module according to a second embodiment of the invention.
  • The figure 4 represents, in section, a light module according to a third embodiment of the invention.

On a représenté en figure 1 une diode électroluminescente organique OLED 1 et en figure 2 un module lumineux 10 comportant un support de diode 11 dans lequel est montée ladite OLED 1.We have shown in figure 1 an organic light-emitting diode OLED 1 and in figure 2 a light module 10 comprising a diode support 11 in which said OLED 1 is mounted.

Le support 11 comporte un corps 12 sur lequel est montée une embase creuse formant un orifice 13 dans lequel est montée ladite OLED 1.The support 11 comprises a body 12 on which is mounted a hollow base forming an orifice 13 in which said OLED 1 is mounted.

L'OLED 1 comporte une partie émettrice de lumière 2 délimitée par deux parois planes en vis-à-vis 21 et 22. Entre les parois 21 et 22 est disposée au moins une couche de matériau organique 23 apte à émettre de la lumière lorsque la diode est alimentée électriquement. L'OLED 1 comporte à cet effet des électrodes, non représentées, destinées à guider le courant électrique dans la couche de matériau organique 23.OLED 1 comprises a light emitting portion 2 delimited by two flat walls facing each other 21 and 22. Between walls 21 and 22 is disposed at least one layer of organic material 23 capable of emitting light when the diode is electrically powered. The OLED 1 comprises for this purpose electrodes, not shown, for guiding the electric current in the layer of organic material 23.

Chaque paroi 21 et 22 est réalisée en un matériau transparent ou translucide, notamment du verre ou du plastique, de sorte à laisser passer de la lumière émise par la couche 23. On constate sur la figure 1 que ladite couche de matériau organique 23 s'étend sur une surface inférieure ou égale à celle des parois 21 et 22 de sorte à être totalement encadrée par ces parois 21 et 22. Les parois 21 et 22 forment ainsi un boîtier étanche enfermant ladite couche de matériau organique 23.Each wall 21 and 22 is made of a transparent or translucent material, in particular glass or plastic, so as to allow light emitted by the layer 23 to pass through. figure 1 that said layer of organic material 23 extends on a surface less than or equal to that of the walls 21 and 22 so as to be completely framed by these walls 21 and 22. The walls 21 and 22 thus form a sealed casing enclosing said layer of organic material 23.

L'OLED 1 comporte en outre une partie de montage 3 destinée à être insérée dans l'orifice 13 du support 11.OLED 1 further comprises a mounting portion 3 intended to be inserted into the orifice 13 of the support 11.

Chaque paroi 21 et 22 délimitant la partie émettrice s'étend depuis une extrémité supérieure de l'OLED 1 jusqu'à une extrémité inférieure de l'OLED 1, de sorte à former chacune une paroi 31 et 32 de la partie de montage 3. Dans l'exemple non limitatif représenté, les parois associées 21 et 31, respectivement 22 et 32, de la partie émettrice 2 et de la partie 3 forment chacune une seule pièce venue de matière.Each wall 21 and 22 delimiting the emitting portion extends from an upper end of the OLED 1 to a lower end of the OLED 1, so as to form each a wall 31 and 32 of the mounting portion 3. In the non-limiting example shown, the associated walls 21 and 31, respectively 22 and 32, of the emitting portion 2 and of the part 3 each form a single piece from material.

On constate sur la figure 1 que la partie émettrice de lumière 2 présente une aire supérieure à celle de la partie de montage 3.We see on the figure 1 the light-emitting portion 2 has an area greater than that of the mounting portion 3.

L'OLED 1 comporte des premier 41 et deuxième 42 moyens de fixation, disposés respectivement sur les parois 31 et 32 de la partie de montage.The OLED 1 comprises first 41 and second 42 fixing means, respectively disposed on the walls 31 and 32 of the mounting portion.

Chaque moyen de fixation 41, 42 est formé par une déformation d'une surface de la paroi 31, 32 de la partie de montage 3 sur laquelle il est disposé. Dans le mode de réalisation non limitatif décrit, les deux moyens 41 et 42 sont structurellement identiques. Par la suite, seul le moyen de fixation 41 de la paroi 31 sera donc décrit.Each fastening means 41, 42 is formed by a deformation of a surface of the wall 31, 32 of the mounting portion 3 on which it is disposed. In the nonlimiting embodiment described, the two means 41 and 42 are structurally identical. Subsequently, only the fastening means 41 of the wall 31 will be described.

Le moyen de fixation 41 est formé par un renfoncement de la paroi 31 de la partie de montage 3, réalisé par un retrait de matière. Le renfoncement est suivi d'une excroissance faisant saillie de la paroi 31, réalisée par ajout de matière. L'excroissance comporte un ressaut suivi d'une pente douce vers l'extrémité inférieure de la partie de montage 3.The fastening means 41 is formed by a recess in the wall 31 of the mounting part 3, made by a withdrawal of material. The recess is followed by a protrusion projecting from the wall 31, made by adding material. The protrusion comprises a projection followed by a gentle slope towards the lower end of the mounting portion 3.

Ces moyens de fixations 41 et 42 sont destinés à coopérer avec des premier et deuxième moyens de fixation complémentaire 51 et 52 du support 11. Les moyens de fixation complémentaires 51 et 52 sont des languettes s'étendant dans l'orifice 13 et aptes à se déformer élastiquement, de sorte à ce que les moyens de fixation 41 et 42 forment des moyens d'encliquetage femelle de la partie de montage 3 et les moyens complémentaires de fixation 51 et 52 du support 11 forment des moyens d'encliquetage male. Ainsi, lorsque la partie de montage 3 est insérée dans le support 11, chaque languette 51 et 52 vient en contact avec la pente douce de l'excroissance en se déformant élastiquement jusqu'à rencontrer le ressaut de façon à s'insérer dans le renfoncement.These fastening means 41 and 42 are intended to cooperate with first and second complementary fastening means 51 and 52 of the support 11. The complementary fastening means 51 and 52 are tabs extending into the orifice 13 and adapted to elastically deform, so that the fastening means 41 and 42 form female latching means of the mounting portion 3 and the complementary fastening means 51 and 52 of the support 11 form male latching means. Thus, when the mounting portion 3 is inserted into the support 11, each tongue 51 and 52 comes into contact with the gentle slope of the protrusion by deforming elastically until it meets the projection so as to fit into the recess .

On comprend que dans le module 10 selon l'invention, c'est la diode électroluminescente 2 elle-même qui comporte les moyens de fixation 41, 42 au support 11, ce qui permet de s'affranchir d'une pièce externe. De plus, la diode 2 étant directement fixée au support 11, on diminue le risque que d'éventuels vibrations et chocs transmis du module au support viennent perturber la fixation.It will be understood that in the module 10 according to the invention, it is the light-emitting diode 2 itself which comprises the fixing means 41, 42 to the support 11, which makes it possible to dispense with an external part. In addition, the diode 2 is directly attached to the support 11, it reduces the risk that any vibrations and shocks transmitted from the module to the support disrupt the fixing.

En outre, la partie de montage 3 de la diode électroluminescente 2 et l'embase du support forment une paire culot/douille standard. Il est ainsi possible de donner à la première partie émettrice de lumière une forme libre.In addition, the mounting portion 3 of the light emitting diode 2 and the base of the support form a pair of standard cap / socket. It is thus possible to give to the first light-emitting part a free form.

L'OLED 2 comporte en outre une piste électrique 6 destiné à son alimentation électrique. Cette piste électrique 6 étant disposé sur la paroi 32 de la partie de montage. Le support 11 comporte un connecteur électrique 7 réalisé sous la forme d'une lame à ressort métallique 7 disposée dans l'orifice 13 et destiné à coopérer avec ladite piste électrique. Le connecteur 7 est reliée à des pistes 8 disposées sur le support 11.OLED 2 further comprises an electrical track 6 for its power supply. This electrical track 6 is disposed on the wall 32 of the mounting portion. The support 11 comprises an electrical connector 7 made in the form of a metal spring blade 7 disposed in the orifice 13 and intended to cooperate with said electrical track. The connector 7 is connected to tracks 8 arranged on the support 11.

On a représenté en figure 3 un module 110 comprenant un support 111 et une OLED 101 selon un deuxième mode de réalisation. Dans ce mode de réalisation de l'invention, le support 111 est en tout point identique au support 11 du mode de la figure 2. En revanche, la deuxième paroi 122 délimitant la partie émettrice de l'OLED 101 s'étend depuis une extrémité supérieure de l'OLED jusqu'à une extrémité supérieure de la partie de montage.We have shown in figure 3 a module 110 comprising a support 111 and an OLED 101 according to a second embodiment. In this embodiment of the invention, the support 111 is in all respects identical to the support 11 of the mode of the figure 2 . In contrast, the second wall 122 defining the emitter portion of the OLED 101 extends from an upper end of the OLED to an upper end of the mounting portion.

On constate ainsi sur la figure 3 que la partie de montage est ainsi formée uniquement par une unique paroi 131, formée par la première paroi 121 de la partie émettrice. La deuxième paroi 122 de la partie émettrice est rapportée sur la première paroi 121 uniquement au niveau de la partie émettrice, de sorte à totalement encapsulée la couche de matériau organique 123.We thus see on the figure 3 that the mounting portion is thus formed only by a single wall 131, formed by the first wall 121 of the emitting part. The second wall 122 of the emitting part is attached to the first wall 121 only at the emitting part, so as to completely encapsulate the layer of organic material 123.

Dans ce mode de réalisation, les premier et deuxième moyens de fixation 141, 142 de la diode 101 sont chacun disposés sur des surfaces opposées de la paroi 131 de la partie de montage. Ces moyens de fixation 141 et 142 sont formés par des déformations similaires aux déformations du mode de réalisation de la figure 1.In this embodiment, the first and second attachment means 141, 142 of the diode 101 are each disposed on opposite surfaces of the wall 131 of the mounting portion. These fixing means 141 and 142 are formed by deformations similar to the deformations of the embodiment of the figure 1 .

En outre, ladite paroi 131 de la partie de montage présente une surépaisseur 143 au niveau de la partie de montage, de façon à améliorer la tenue mécanique de la diode 101 sur son support 111.In addition, said wall 131 of the mounting portion has an extra thickness 143 at the mounting portion, so as to improve the mechanical strength of the diode 101 on its support 111.

On a représenté en figure 4 un module 200 comprenant un support 211 et deux OLEDs 201 selon un troisième mode de réalisation. Les OLEDs 201 sont semblables en tout point à l'OLED 1 du mode de réalisation de la figure 1.We have shown in figure 4 a module 200 comprising a support 211 and two OLEDs 201 according to a third embodiment. OLEDs 201 are similar in all respects to OLED 1 of the embodiment of the figure 1 .

Le support 211 comporte un corps 212 et deux embases, notamment montées de part et d'autre du corps 212, chaque embase formant un orifice de montage 213 d'une OLED 201, similire à l'orifice de montage 13 du mode de réalisation de la figure 2.The support 211 comprises a body 212 and two bases, in particular mounted on either side of the body 212, each base forming a mounting hole 213 of an OLED 201, similar to the mounting hole 13 of the embodiment of FIG. the figure 2 .

Les modes de réalisation de l'invention servant de base à la présente description ne sont pas limitatifs, pour autant qu'ils permettent d'obtenir les effets techniques tels que revendiqués.The embodiments of the invention forming the basis of the present description are not limiting, provided that they make it possible to obtain the technical effects as claimed.
