Description

MODULE LUMINEUX COMPORTANT UNE DIODE ELECTROLUMINESCENTE ORGANIQUE  LIGHT-EMITTING MODULE COMPRISING AN ORGANIC ELECTROLUMINESCENT DIODE
[001] L'invention concerne le domaine technique de l'éclairage et de la signalisation des véhicules automobiles, et s'intéresse en particulier aux modules lumineux destinés à être intégrés dans des boîtiers d'éclairage et/ou de signalisation comportant des diodes électroluminescentes organiques connues également sous l'acronyme anglo-saxon OLED (Organic Light Emiting Diode). [001] The invention relates to the technical field of lighting and signaling of motor vehicles, and is particularly interested in light modules intended to be integrated into lighting and / or signaling housings comprising light emitting diodes. organic known also under the acronym OLED (Organic Light Emitting Diode).
[002] 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. Ainsi, des démonstrateurs regroupant plusieurs diodes électroluminescentes de même couleur ou de couleurs différentes ont été présentés récemment sur des véhicules expérimentaux. [002] Recent technological advances, which tend to extend the life span and reduce the manufacturing costs of organic light-emitting diodes, have increased the interest of stylists and vehicle designers for 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. Thus, demonstrators grouping several light-emitting diodes of the same color or of different colors have been presented recently on experimental vehicles.
[003] Ces diodes électroluminescentes organiques offrent également l'avantage d'être peu consommatrices d'énergie. [003] These organic light emitting diodes also have the advantage of being low energy consumers.
[004] Une diode électroluminescente organique se présente généralement sous la forme d'une lame mince comprenant un substrat généralement en verre sur lequel sont superposées une anode et une cathode entre lesquelles une ou plusieurs couches de matière organique contenant par exemple des matériaux tels que des polyanilines ou des polyfluorènes sont disposées. Cette forme d'exécution n'est pas limitative, puisque sortent dorénavant des laboratoires des diodes électroluminescentes organiques réalisées sur des substrats souples. [005] En raison de la fragilité du substrat de verre, les systèmes existants utilisant ces types de diodes intègrent des cadres entourant complètement la diode par sa périphérie, pour protéger la diode pendant les manipulations successives intervenant tout au long du processus d'assemblage. Ces cadres présentent toutefois l'inconvénient de limiter les effets de styles. [006] En effet, pour améliorer les effets lumineux recherchés, les stylistes cherchent à ne faire apparaître que la seule surface émettrice de lumière, et à maintenir hors de la vue d'un observateur regardant le véhicule, les éléments techniques nécessaires au - - fonctionnement de la diode électroluminescente organique. An organic light-emitting diode is generally in the form of a thin plate comprising a generally glass substrate on which are superimposed an anode and a cathode between which one or more layers of organic material containing for example materials such as polyanilines or polyfluorenes are provided. This embodiment is not limiting, since now come from laboratories organic light emitting diodes made on flexible substrates. Due to the fragility of the glass substrate, the existing systems using these types of diodes integrate frames completely surrounding the diode by its periphery, to protect the diode during the successive manipulations involved throughout the assembly process. However, these frames have the disadvantage of limiting the effects of styles. [006] Indeed, to improve the desired lighting effects, the stylists seek to reveal only the light emitting surface, and to keep out of the sight of an observer looking at the vehicle, the technical elements necessary for operation of the organic light-emitting diode.
[007] Par ailleurs, en raison de leur destination, une attention très forte est portée à la maintenabilité et à l'interopérabilité de ces dispositifs ainsi qu'au processus de montage et d'assemblage dans le véhicule, au cours duquel il est primordial de préserver l'intégrité des composants tout en mettant sous contrôle les coûts d'assemblage. [007] Moreover, because of their destination, very strong attention is paid to the maintainability and interoperability of these devices and to the assembly and assembly process in the vehicle, during which it is essential. maintain component integrity while controlling assembly costs.
[008] Enfin, si la plus grande part de la surface de la paroi de la diode est réservée à la zone émettrice de lumière, il reste néanmoins nécessaire de prévoir des moyens de liaison électrique avec des organes de commande du véhicule, ainsi que des moyens mécaniques de liaison avec l'organe de signalisation. [009] L'ensemble de ces impératifs techniques, économiques et esthétiques limitent donc l'usage de caches destinés à masquer les éléments techniques, ou de cadres de maintien enserrant la diode électroluminescente par sa périphérie. [008] Finally, if most of the surface of the wall of the diode is reserved for the light emitting zone, it nevertheless remains necessary to provide electrical connection means with vehicle control members, as well as mechanical means of connection with the signaling member. [009] All these technical, economic and aesthetic requirements therefore limit the use of caches for masking the technical elements, or holding frames enclosing the light-emitting diode by its periphery.
[0010] L'invention a pour objet d'apporter une solution technique à cette problématique. The invention aims to provide a technical solution to this problem.
[0011] Le module lumineux selon l'invention, destiné à être intégré dans un boîtier d'éclairage et/ou de signalisation, comprend The light module according to the invention, intended to be integrated into a lighting and / or signaling unit, comprises
un support comportant au moins une première surface dite de séparation, au moins une diode électroluminescente organique comportant une première partie émettrice de lumière, des moyens d'accrochage de la diode sur le support et des moyens de connexion électrique de la diode. [0012] Ce module lumineux se caractérise en ce que :  a support comprising at least a first so-called separation surface, at least one organic light-emitting diode comprising a first light-emitting part, means for attaching the diode to the support, and means for electrically connecting the diode. This light module is characterized in that:
les moyens d'accrochage de la diode et les moyens de connexion électrique de la diode sont portés par une partie de cette diode, dite partie de raccordement, la surface de séparation du support délimite une zone de diffusion de lumière dans laquelle s'étend la première partie émettrice de lumière de la diode, et sépare cette zone de diffusion de lumière d'une zone masquée, dans laquelle s'étend la partie de raccordement de la diode, de sorte que ladite partie de raccordement est occultée par la surface de séparation du support.  the attachment means of the diode and the electrical connection means of the diode are carried by a part of this diode, said connection portion, the separation surface of the support defines a light scattering zone in which extends the first light-emitting part of the diode, and separates this light scattering zone from a masked area, in which the connecting portion of the diode extends, so that said connecting portion is obscured by the separation surface of the support.
[0013] La surface de séparation doit ici être comprise comme étant en règle générale la partie de la surface du support visible de l'extérieur du véhicule dans lequel ledit module lumineux est destiné à être monté. A ce titre, cette surface de séparation peut faire partie intégrante du style général du véhicule. On pourra toutefois également prévoir de la - - recouvrir ou de la dissimuler par un masque, afin de cacher les imperfections et défauts de cette surface de séparation. The separation surface here must be understood as being in general the portion of the surface of the support visible from the outside of the vehicle wherein said light module is intended to be mounted.

Les figures 10, 1 1 et 12 représentent des vues en perspective d'un module lumineux selon l'invention inséré dans un boîtier de signalisation présentant des effets de style variés. [0042] La figure 1 représente un fragment de support 10 formé d'une paroi 100 comportant une surface de séparation 101 .  Figures 10, 1 1 and 12 show perspective views of a light module according to the invention inserted into a signal box with various style effects. FIG. 1 represents a support fragment 10 formed of a wall 100 having a separation surface 101.
[0043] Une diode électroluminescente organique 20 est insérée dans une entaille 1 10 traversant la paroi 100 du support 10, comme cela est illustré à la figure 2. - - An organic light-emitting diode 20 is inserted into a notch 1 10 passing through the wall 100 of the support 10, as illustrated in FIG. 2. - -
[0044] Cette diode électroluminescente comporte une partie émettrice de la lumière 200 et une partie de raccordement 210, séparées par une ligne fictive en pointillée 201 située dans l'alignement précis de la surface de séparation 101 . This light-emitting diode comprises a light emitting portion 200 and a connecting portion 210, separated by a dotted line 201 in the precise alignment of the separation surface 101.
[0045] La partie de raccordement 210 est donc placée de l'autre côté de la surface de séparation 101 , et reste masquée par ladite surface pour un observateur placé à l'extérieur du véhicule. The connecting portion 210 is placed on the other side of the separation surface 101, and remains hidden by said surface for an observer placed outside the vehicle.
[0046] Dans cette forme d'exécution de l'invention, la partie de raccordement traverse entièrement la paroi 100 du support et émerge du côté de la surface 102 de la paroi 100, opposée à la surface de séparation 101 , et dénommée surface technique en ce qu'elle n'est pas visible de l'extérieur du véhicule. In this embodiment of the invention, the connecting portion completely through the wall 100 of the support and emerges from the side of the surface 102 of the wall 100, opposite the separation surface 101, and called technical surface in that it is not visible from outside the vehicle.
[0047] La forme générale de la diode électroluminescente organique est celle d'une lame plane et mince, bordée par des tranches de faible épaisseur 213, 214, 215. The general shape of the organic electroluminescent diode is that of a flat and thin blade, bordered by thin slices 213, 214, 215.
[0048] La paroi de la partie de raccordement 210 de la diode électroluminescente organique comprend deux excroissances latérales 21 1 et 212. Les tranches d'appui inférieures 213 et 214 des excroissances latérales regardant la partie émettrice de lumière viennent en appui contre la surface technique 102 de manière à limiter la course de la diode dans l'entaille 1 10, de sorte que la ligne fictive 201 séparant la partie émettrice de lumière 200 de la partie de raccordement 210 puisse être située exactement au niveau de la surface de séparation 101 . [0049] Pour rattraper les jeux de positionnement, les tranches d'appui inférieures 213 et 214 peuvent utilement être des pans inclinés convergents. La partie de raccordement 210 de la diode 20 présente alors une forme globalement trapézoïdale dont la petite base est prolongée par la partie émettrice de lumière 200. Dans le cas illustré par la figure 1 , les tranches d'appui inférieures 213 et 214 viennent directement en contact avec les extrémités latérales 1 1 1 et 1 12 de l'entaille 1 10, lesquelles ont également une forme correspondante en pan incliné de manière à favoriser une bonne mise en place de la diode dans l'entaille. The wall of the connecting portion 210 of the organic light-emitting diode comprises two lateral protrusions 21 1 and 212. The lower support slices 213 and 214 of the lateral protrusions facing the light-emitting part come to bear against the technical surface 102 so as to limit the stroke of the diode in the notch 1 10, so that the imaginary line 201 separating the light emitting portion 200 from the connecting portion 210 can be located exactly at the separation surface 101. To catch the positioning sets, the lower support slices 213 and 214 can usefully be inclined convergent sections. The connection portion 210 of the diode 20 then has a generally trapezoidal shape whose small base is extended by the light-emitting portion 200. In the case illustrated in FIG. 1, the lower support portions 213 and 214 come directly into position. contact with the lateral ends 1 1 1 and 1 12 of the notch 1 10, which also have a corresponding shape inclined pan so as to promote proper placement of the diode in the notch.
[0050] Le mode d'exécution de l'invention tel que représenté aux figures 1 et 2, dans lequel la paroi 100 du support 10 est traversée de part en part par la diode électroluminescente, et dans lequel la partie de raccordement ressort du côté de la surface technique, ne doit pas être considéré comme un mode de réalisation unique de l'invention. - - The embodiment of the invention as shown in Figures 1 and 2, wherein the wall 100 of the support 10 is traversed from one side by the light emitting diode, and wherein the connecting portion is on the side of the technical surface, should not be considered as a single embodiment of the invention. - -
[0051] Les figures 3a et 3b permettent d'illustrer des modes d'exécution également compris dans le champ de l'invention. Figures 3a and 3b illustrate embodiments also included in the scope of the invention.
[0052] La figure 3a illustre le cas dans lequel le support comprend deux surfaces de séparation 101 a et 101 b, situées en vis-à-vis l'une de l'autre, et dans lequel la diode électroluminescente comprend deux parties émettrices de lumière 200a et 200b situées de part et d'autre de la partie de raccordement 210 disposée entre les deux surfaces de séparation 101 a et 101 b. FIG. 3a illustrates the case in which the support comprises two separation surfaces 101a and 101b, situated opposite one another, and in which the light-emitting diode comprises two transmitting parts of light 200a and 200b located on either side of the connecting portion 210 disposed between the two separation surfaces 101a and 101b.
[0053] La figure 3b illustre le cas dans lequel la partie de raccordement 210 est placée entre la surface de séparation 101 et la surface technique 102, et ne traverse pas la paroi 100 du support. FIG. 3b illustrates the case in which the connecting portion 210 is placed between the separation surface 101 and the technical surface 102, and does not pass through the wall 100 of the support.
[0054] En outre, la présente invention englobe également des variantes de réalisations dans lesquels les parties émettrices de lumière 200, 200a et 200b des diodes sont subdivisées en plusieurs sous-secteurs dont l'allumage est commandé indépendamment les uns des autres. [0055] Les figures 4, 5 et 6 permettent d'illustrer une variante de réalisation de la première alternative d'exécution de l'invention, dans laquelle une bordure de centrage 120, prenant ici la forme d'une paroi, est disposée sur la surface technique du support. La surface interne 121 de la bordure de centrage entoure la périphérie de l'entaille 1 10. [0056] Cette bordure de centrage permet de consolider le maintien de la diode électroluminescente organique dans l'entaille. In addition, the present invention also encompasses embodiments in which the light emitting portions 200, 200a and 200b of the diodes are subdivided into a plurality of subsectors whose ignition is controlled independently of each other. Figures 4, 5 and 6 illustrate an alternative embodiment of the first alternative embodiment of the invention, wherein a centering edge 120, here taking the form of a wall, is disposed on the technical surface of the support. The inner surface 121 of the centering edge surrounds the periphery of the notch 1 10. This centering edge makes it possible to consolidate the maintenance of the organic light-emitting diode in the notch.
[0057] Il est également possible d'incliner la surface interne 121 de la bordure de centrage d'un angle (a) par rapport à la surface technique 102, lorsque l'on désire faire ressortir les diodes électroluminescentes avec une inclinaison relative par rapport à une direction normale à la surface de séparation 101 , comme cela est illustré à la figure 5. It is also possible to incline the inner surface 121 of the centering edge by an angle (a) with respect to the technical surface 102, when it is desired to bring out the light-emitting diodes with a relative inclination relative to in a direction normal to the separation surface 101, as shown in FIG. 5.
[0058] Les parties de la surface interne 121 qui sont en contact avec les tranches d'appui inférieures 213, 214 inclinées de la partie de raccordement peuvent également avoir une forme en biseau prolongeant la forme des extrémités latérales 1 1 1 et 1 12 de l'entaille 1 10. [0059] Un élément de blocage libérable 30 est disposé sur la bordure de centrage 120. - - The portions of the inner surface 121 which are in contact with the lower bearing edges 213, 214 inclined of the connecting portion may also have a bevel shape extending the shape of the lateral ends 1 1 1 and 1 12 of the notch 1 10. [0059] A releasable locking element 30 is disposed on the centering edge 120. - -
[0060] En position fermée l'élément bloquant vient reposer sur la tranche d'appui supérieure 215 de la diode électroluminescente de manière à maintenir cette dernière dans l'entaille. En position ouverte, il autorise l'extraction de la diode. In the closed position the blocking element comes to rest on the upper support portion 215 of the light emitting diode so as to maintain the latter in the notch. In the open position, it allows the extraction of the diode.
[0061] La face de l'élément bloquant 30 en contact avec la tranche d'appui supérieure 215 de la diode électroluminescente peut comporter des nervures 301 pour favoriser le contact entre ces deux organes. The face of the blocking element 30 in contact with the upper support portion 215 of the light emitting diode may include ribs 301 to promote contact between these two bodies.
[0062] L'élément bloquant 30 est monté sur la bordure de centrage 120 par l'intermédiaire d'une articulation 302, et comporte un moyen de verrouillage libérable collaborant avec un dispositif correspondant disposé sur la surface technique ou sur la bordure de centrage elle-même. The blocking element 30 is mounted on the centering edge 120 via a hinge 302, and comprises a releasable locking means collaborating with a corresponding device disposed on the technical surface or on the centering edge thereof. -even.
[0063] On observera ici que l'articulation de cet élément bloquant peut tout aussi bien être montée directement sur la paroi 100 du support du côté de la surface technique 102. It will be observed here that the articulation of this blocking element can just as easily be mounted directly on the wall 100 of the support on the side of the technical surface 102.
[0064] A titre d'exemple, le moyen de verrouillage libérable peut être composé d'un premier élément de fixation par clipsage 304 collaborant avec un deuxième élément de fixation par clipsage 131 disposé sur la surface technique, ou sur la bordure de centrage comme cela est illustré à la figure 5, ou encore d'un œillet 303 disposé sur le côté opposé de l'articulation 302, coaxial, en position fermée, avec un trou 130 réalisé dans la bordure de centrage, ou dans la paroi 10 du support 100 comme cela est illustré à la figure 6, et permettant de recevoir une vis de blocage. [0065] On notera que si l'élément bloquant ne comporte pas d'articulation, ces moyens de verrouillage libérables peuvent être combinés deux à deux entre eux ou avec eux- mêmes. By way of example, the releasable locking means may be composed of a first clipping fastening element 304 collaborating with a second clipping fastening element 131 disposed on the technical surface, or on the centering rim as shown in FIG. this is illustrated in Figure 5, or an eyelet 303 disposed on the opposite side of the hinge 302, coaxial, in the closed position, with a hole 130 formed in the centering edge, or in the wall 10 of the support 100 as shown in Figure 6, and to receive a locking screw. Note that if the blocking element does not have a hinge, these releasable locking means can be combined two by two with each other or with themselves.
[0066] Le contact entre les moyens de connexion électrique disposés sur la partie de raccordement de la diode électroluminescente et les moyens d'alimentation et de commande provenant du véhicule peuvent utilement se faire au niveau des tranches d'appui inférieures 213 et 214, ou encore au niveau de la tranche d'appui supérieure 215. Les moyens de raccordement électrique correspondants sont alors disposés respectivement sur la surface technique 102 ou sur les surfaces de l'entaille 1 1 1 et 1 12, en contact avec les tranches d'appui inférieures 213 ou 214, ou encore sur la surface de l'élément bloquant 30 en contact avec la tranche d'appui supérieure 215. Selon une variante de réalisation avantageuse, les moyens de connexion électrique peuvent être directement intégrés dans le matériau constitutif du support 10, à tout le - - moins sur la surface technique 102, en faisant appel aux techniques de plastronique permettant de réaliser un dispositif interconnecté moulé (également dénommé MID pour « molded interconnect device »), avec notamment création de pistes conductrices sur la surface technique 102. [0067] Les figures 7 et 8 représentent une seconde alternative de réalisation de l'invention, dans laquelle la diode électroluminescente est reliée au support au moyen d'un module de fixation intermédiaire 50. The contact between the electrical connection means arranged on the connection portion of the light emitting diode and the power supply and control means from the vehicle can usefully be at the lower support slices 213 and 214, or still at the level of the upper support section 215. The corresponding electrical connection means are then respectively arranged on the technical surface 102 or on the surfaces of the notch 1 1 1 and 1 12, in contact with the support slices below 213 or 214, or on the surface of the blocking element 30 in contact with the upper support section 215. According to an advantageous embodiment, the electrical connection means can be directly integrated in the material constituting the support 10 , at all - - less on the technical surface 102, using plastronics techniques to achieve a molded interconnected device (also called MID for "molded interconnect device"), including creating conductive tracks on the technical surface 102. [0067] FIGS. 7 and 8 show a second alternative embodiment of the invention, in which the light-emitting diode is connected to the support by means of an intermediate fixing module 50.
[0068] L'intérêt de cette solution alternative repose essentiellement dans la facilité de raccordement et de montage de la diode sur le support au moment de l'assemblage et aussi lors des opérations de maintenance, pour assurer le remplacement de diodes défectueuses. The advantage of this alternative solution lies essentially in the ease of connection and mounting of the diode on the support at the time of assembly and also during maintenance operations, to ensure the replacement of defective diodes.
[0069] Dans les exemples servant de support à la présente description, le module de fixation intermédiaire est composé de deux barrettes de maintien 501 et 502 venant enserrer les surfaces d'appui opposées 216,217, de la partie de raccordement 210 de la diode électroluminescente organique, comme cela est représenté aux figures 7d et 8d. In the examples used to support the present description, the intermediate fixing module is composed of two holding bars 501 and 502 coming to grip the opposite bearing surfaces 216, 217, of the connection portion 210 of the organic light-emitting diode. as shown in FIGS. 7d and 8d.
[0070] Les deux barrettes sont reliées l'une à l'autre par des moyens de serrage libérables autorisant le montage et le démontage de la diode électroluminescente. The two bars are connected to each other by releasable clamping means allowing the assembly and disassembly of the light emitting diode.
[0071] A titre d'exemple les figures 7a, 7b, 7c et 8a, 8b et 8c, permettent d'illustrer les détails de montage des barrettes selon deux variantes possibles et non limitatives d'exécution. By way of example, FIGS. 7a, 7b, 7c and 8a, 8b and 8c illustrate the mounting details of the bars according to two possible and non-limiting embodiments.
[0072] Dans la première variante d'exécution illustrée par les figures 7a, 7b et 7c, les deux barrettes de maintien 501 et 502, sont reliées l'une à l'autre par des éléments de clipsage 505, 506, disposés respectivement sur les faces opposées de chacune des barrettes et venant s'encliqueter les uns dans les autres. [0073] Dans la seconde variante d'exécution illustrée par les figures 8a, 8b et 8c, les deux barrettes 51 1 et 512 sont reliées entre elles par des éléments mâles 516 disposés sur une première barrette 51 1 et emmanchés en force dans des trous 515 aménagés dans la seconde barrette 512. Pour assurer un bon maintien de l'emmanchement, les éléments mâles peuvent avoir une forme légèrement conique. Le verrouillage des deux barrettes entre elles peut alors être effectué par bouterollage des extrémités libre des éléments mâles. - - In the first embodiment shown in FIGS. 7a, 7b and 7c, the two holding bars 501 and 502 are connected to one another by clipping elements 505, 506, respectively disposed on the opposite faces of each of the bars and snap into each other. In the second embodiment shown in Figures 8a, 8b and 8c, the two bars 51 1 and 512 are interconnected by male elements 516 disposed on a first bar 51 1 and force-fitted into holes 515 arranged in the second bar 512. To ensure a good fit of the fitting, the male elements may have a slightly conical shape. The locking of the two bars together can then be done by pebbling the free ends of the male elements. - -
[0074] La liaison entre les barrettes peut également se faire par vissage, ou encore par collage ou par soudage, en considérant alors dans ces derniers cas que le module de liaison intermédiaire n'est plus détachable de la diode. The connection between the bars can also be done by screwing, or by gluing or welding, considering then in the latter case that the intermediate link module is no longer detachable from the diode.
[0075] Pour améliorer le contact entre les barrettes et la partie de raccordement de la diode électroluminescente, il peut s'avérer utile de disposer sur les faces internes des dites barrettes des pattes d'appui 503 assurant une liaison élastique avec les surfaces d'appui 216, 217, de ladite partie de raccordement 210 de la diode 20. To improve the contact between the bars and the connection portion of the light emitting diode, it may be useful to have on the inner faces of said bars support lugs 503 providing an elastic connection with the surfaces of the light-emitting diode. support 216, 217, of said connecting portion 210 of the diode 20.
[0076] A cet effet, chacune des pattes d'appui 503 est venue de matière par un de ses côtés avec la barrette, et vient en contact avec la surface d'appui de la partie de raccordement de la diode par le côté opposé à cette liaison. Le corps de la patte d'appui est décalé du côté interne de la barrette. En jouant avec l'élasticité du matériau ou avec l'épaisseur de la patte d'appui au niveau de la liaison entre la patte d'appui 503 et la barrette on peut utilement régler la force de serrage entre la surface d'appui 216, 217 de la partie de raccordement 210 de la diode et les barrettes de maintien 501 et 502. [0077] Le contact électrique entre la partie de raccordement de la diode et les éléments d'alimentation et de commande du véhicule peut se faire utilement au niveau des pattes d'appui portant sur la surface de la partie de raccordement. For this purpose, each of the support lugs 503 is made of material by one of its sides with the bar, and comes into contact with the bearing surface of the connecting portion of the diode by the opposite side to this connection. The body of the support leg is offset on the inner side of the bar. By playing with the elasticity of the material or with the thickness of the support lug at the level of the connection between the bearing lug 503 and the bar, it is useful to adjust the clamping force between the bearing surface 216, 217 of the connecting portion 210 of the diode and the holding bars 501 and 502. [0077] The electrical contact between the connecting portion of the diode and the power supply and control elements of the vehicle can usefully be bearing lugs on the surface of the connecting portion.
[0078] Au moins une des barrettes comporte des excroissances de positionnement 520 destinées à venir en contact avec les tranches d'appui inférieures 213 et 214 et la tranche d'appui supérieure 215 de la partie de raccordement de la diode électroluminescente de manière à limiter les mouvements de cette dernière. At least one of the strips comprises positioning protrusions 520 intended to come into contact with the lower support sections 213 and 214 and the upper support section 215 of the connection portion of the light-emitting diode so as to limit the movements of the latter.
[0079] Une des barrettes comporte des moyens de liaison avec le support 10. A titre d'exemple, la barrette illustrée aux figures 7c et 7d comporte des œillets 530. One of the bars comprises connecting means with the support 10. For example, the bar illustrated in Figures 7c and 7d has eyelets 530.
[0080] Selon une variante d'exécution non représentée, les deux barrettes de maintien peuvent être reliées entre elles par une charnière souple. Elles peuvent ainsi former une pièce d'un seul tenant et de matière, obtenue par moulage. According to an alternative embodiment not shown, the two holding bars can be interconnected by a flexible hinge. They can thus form a piece in one piece and material, obtained by molding.
[0081] La figure 9 permet de visualiser le montage sur un support 10, de plusieurs modules de fixation intermédiaire comportant chacun une diode électroluminescente. Figure 9 shows the mounting on a support 10, several intermediate fixing modules each having a light emitting diode.
[0082] La paroi 100 du support comprend des entailles dans lesquelles sont glissées les diodes électroluminescentes de sorte que seule ladite partie émettrice de lumière 200 émerge de la surface de séparation 101. - - The wall 100 of the support comprises notches in which the light-emitting diodes are slid so that only said light-emitting part 200 emerges from the separation surface 101. - -
[0083] La paroi du support comprend également des protubérances, prenant la forme de futs cylindriques 132, disposées du côté de la surface technique 102. Ces protubérances 132 comportent des trous, ajustés pour être coaxiaux avec les œillets 530 placés sur les modules intermédiaires supportant la diode, et aptes à recevoir une vis de fixation 133 au moment de l'assemblage. The wall of the support also comprises protuberances, taking the form of cylindrical barrels 132, disposed on the side of the technical surface 102. These protuberances 132 comprise holes, adjusted to be coaxial with the eyelets 530 placed on the intermediate modules supporting the diode, and adapted to receive a fixing screw 133 at the time of assembly.
[0084] Bien évidemment, ce moyen de liaison par vissage entre le module de fixation intermédiaire et le support n'est pas limitatif. Il est ainsi tout à fait possible d'envisager un moyen de liaison par clipsage, par emboîtage, ou encore par collage ou par soudure si on abandonne l'idée de rendre le module de fixation intermédiaire démontable par rapport au support. Of course, this connection means by screwing between the intermediate fixing module and the support is not limiting. It is thus quite possible to envisage a connection means by clipping, by fitting, or by gluing or welding if we abandon the idea of making the intermediate fixing module removable from the support.
[0085] Le module lumineux 10 représenté à la figure 9 comprend une pluralité de diodes électroluminescentes faisant chacune un angle choisi avec la surface de séparation 102 de manière à créer l'effet de style recherché. The light module 10 shown in Figure 9 comprises a plurality of light emitting diodes each making a chosen angle with the separation surface 102 so as to create the desired style effect.
[0086] La figure 10 illustre un mode d'intégration d'un module lumineux selon l'invention dans un boîtier d'éclairage et /ou de signalisation 60. En particulier, le boîtier 60 est muni de rainures dans lesquelles des languettes ou les bords latéraux du support 100 du module 10 vient s'engager ; le module est ainsi inséré dans le boîtier par coulissement dans ces rainures. FIG. 10 illustrates a mode of integration of a light module according to the invention into a lighting and / or signaling box 60. In particular, the housing 60 is provided with grooves in which tabs or side edges of the support 100 of the module 10 is engaged; the module is thus inserted into the housing by sliding in these grooves.
[0087] Les figures 1 1 et 12 permettent de visualiser les effets de style rendus possibles par l'invention. Les parties émettrices de lumière 200 émergent de la surface de séparation 101 selon des angles et des orientations variées sans laisser deviner la présence des éléments techniques situés de l'autre côté de ladite surface de séparation. Figures 1 1 and 12 show the style effects made possible by the invention. The light emitting portions 200 emerge from the separation surface 101 at various angles and orientations without suggesting the presence of the technical elements located on the other side of said separation surface.
[0088] 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. Embodiments of the invention serving as a basis for the present description are not limiting, as far as they make it possible to obtain the technical effects as claimed.
[0089] Ainsi par exemple, on pourra prévoir que la surface de séparation 101 soit réfléchissante. De même, afin d'améliorer le rendu esthétique, on pourra prévoir que le module comporte un masque additionnel, muni d'orifices de passage des diodes 200, destiné à recouvrir la surface de séparation 101 et cacher les imperfections de cette surface. For example, it can be provided that the separation surface 101 is reflective. Similarly, to improve the aesthetic rendering, it can be provided that the module comprises an additional mask, provided with diode passage holes 200, for covering the separation surface 101 and hide the imperfections of this surface.
