    Support of a luminous means for a motor vehicle
    The field of the present invention is that of lighting and / or signaling devices for motor vehicles, and the present invention relates more particularly to light devices which use at least one organic light-emitting diode.
    Motor vehicle light devices must meet functional criteria on the one hand, such as the light power and the specific arrangement for producing a determined and regulatory beam, or a long service life, a small footprint, ease of implementation, and they must also meet the aesthetic conditions imposed by car manufacturers for visual identification of their vehicle.
    The use of light sources using one or more light-emitting diodes has become frequent.
    We are more recently witnessing the use of organic light emitting diodes, also designated in the following by its English acronym OLED (Organic Light Emitting Diode), is conventionally composed of
    0 two electrodes (an anode and a cathode) between which are placed at least one emission layer, made of an electroluminescent material, as well as a set of electronic transport layers, emission layer and electronic transport layers all made from organic materials. In order to excite the transport layers and in the emission layer and obtain the electroluminescence of the material constituting said emission layer, an electrical voltage must be applied between the two electrodes.
    Although the light power emitted by an OLED diode source remains lower than that emitted by a source with non-organic light emitting diodes (or LEDs, for Light Emitting Diode), such sources are increasingly used in the automotive field, both for the lighting or the signaling of the vehicle itself as for aesthetic reasons, and in particular of the visual and luminous signature of the vehicle.
    A light source of the OLED diode type for a motor vehicle generally consists of an emissive part arranged facing a lens for closing a projector and a connection part by which this light module is connected to a device for power and control of the lighting and / or signaling device of the vehicle. The connection part is mounted in a support from which the emissive part extends.
    The present invention relates to a support for at least one light means for a motor vehicle, said support comprising a base for attachment to a structural element of the vehicle and at least one support module configured to form a housing for receiving said light means. According to the invention, at least part of said support module is made of a transparent or translucent material.
    In particular, this part of the support module can be intended to be visible from outside the vehicle when the support is fixed to the structural element.
    Therefore, both when the light means is on or off, the emissive part can give the impression of being suspended from the support, which offers interesting design perspectives. These arrangements of light sources can thus be made even more attractive, in particular by increasing the impression that the light sources are floating in the associated light module.
    It is understood that according to the invention, the light means may be a means of lighting the road, a means of signaling the vehicle or a means of lighting the interior of the vehicle.
    Provision may be made for the support to include the light means.
    In a particular embodiment, the support module comprises a bottom wall against which said light means can be pressed and which is bordered by a holding frame, at least said holding frame being made of a transparent material or translucent.
    According to different characteristics of the invention, taken alone or in combination, it can be provided that:
    - The retaining frame comprises at least stops extending substantially perpendicularly from the bottom wall; the retaining frame extends substantially perpendicularly to the bottom wall, thereby defining a housing capable of receiving the connection part;
    - The retaining frame comprises a set of first side walls arranged parallel on the short sides of the bottom wall and two stops extending substantially perpendicularly one end of the side walls close to each other, so as to narrow the passage between the first side walls;
    0 - the stops cooperate with the shoulder edges of the connection part of the organic light-emitting diode;
    - the bottom wall is extended by a support tab which extends in the plane of the bottom wall beyond the stops;
    - The bottom wall has a pin configured as a means of indexing said light means; the pin extends projecting from the bottom wall of the support means;
    - The pin is made of a transparent or translucent material, and advantageously the same material as that used to make the retaining frame extending from the bottom wall of the support module;
    - The bottom wall of the support module comprises conductive pads 5 configured to be connected to a metal part of the light means;
    - The bottom wall comprises an adhesive layer configured to maintain in position te light means;
    - The adhesive layer incorporates metallic means forming said conductive pads;
    îo - the bottom wall may comprise, alternatively or cumulatively to what has just been presented, at least one elastically deformable means arranged to maintain in position the first light means; by way of nonlimiting example, provision may be made to equip the bottom wall with an elastic tab, or with a spring; this elastic means can be made of an electrically conductive material so as to be able to be connected to a metal part of the light means; alternatively, provision may be made for screws and a counterpart to press the light means on the bottom wall;
    - The transparent or translucent material is poylcarbonate or polymethyl methacrylate;
    - The support module extends substantially perpendicularly from the attachment base to the structural element.
    According to another series of characteristics of the invention, taken alone or in combination, it can be provided that:
    - The support is configured so that, when your organic light emitting diodes are in place in their respective support module, the base is hidden by the body of the diodes;
    - The emissive part of the organic light-emitting diode may include one or more distinct illuminating surfaces;
    The invention also relates to a light device for a motor vehicle, comprising at least one module for supporting a light means as presented above. The light means comprises an emissive part and a connection part and the device is arranged so that the connection part is fixed in a housing of the support module while the emissive part extends projecting from the support module. In this context, the transparent or translucent part of the support module surrounds the connection part of the lighting and / or signaling means.
    Advantageously, the light means is an organic light-emitting diode. This diode can in particular be a flexible diode.
    The light means may include a bore configured to be engaged around a pin projecting from the bottom wall of the support module, the pin being made of transparent or translucent material.
    Other characteristics and advantages of the present invention will become more clearly apparent from the description and the drawings, among which:
    Figure 1 is a perspective view of a support according to a first embodiment of the invention, configured to receive a plurality of organic light emitting diodes (OLED);
    0 - Figure 2 is a perspective view of a detail of the support of Figure 1, in an exploded representation of the diode and the support;
    Figure 3 is a view similar to that of Figure 2, in which the diode and the support are recessed; and Figure 4 is a perspective view of an alternative embodiment of the support according to the invention.
    It should first of all be noted that if the figures show the invention in detail for its implementation, said figures can of course be used to better define the invention if necessary.
    In FIG. 1, a lighting and / or signaling device 2 comprises a support 4 common to a plurality, here three, of lighting and / or signaling means 6.
    This lighting and / or signaling device can be applied in a headlight or a rear light of the vehicle. It will be understood that other applications can be envisaged, in particular for interior lighting and / or signaling devices. Furthermore, the lighting means are here arranged so as to extend substantially vertically, and in horizontal series, but it will be understood that other orientations could be envisaged without departing from the context of the invention.
    The common support 4 comprises a base 8, having the shape of a plate, and a plurality of support modules 10, configured to respectively receive an organic light-emitting diode 12, and extending the base substantially perpendicularly, it being understood that an angle d he tilt between the base and the support modules could be defined.
    According to different variants, the base 8 and the support modules 10 can be produced independently and subsequently fixed together, or else be formed in one piece, in a single piece, it being noted that by one piece, it is meant that the plate and the support member cannot be
    0 separated without damaging one and / or the other.
    It will be understood that each support module could be independent of the other support modules, and a single support module will be described below with reference to FIGS. 2 to 4.
    The base 8 is configured to be fixed to the structure of the motor vehicle, and possibly to carry means for controlling the lighting and / or signaling means. When the organic light-emitting diodes 12 are in place in their respective support module 10, it is notable that the base 8 is hidden by the body of the diodes 12.
    The organic light-emitting diode 12, or OLED diode, comprises an emissive part 14, and a connection part 16 intended to allow the electrical connection of the emissive part with an electrical supply and / or control device for the signaling assembly. and / or vehicle lighting, not shown here. The emissive part 14 is conventionally composed of a set of polymer layers sandwiched between an anode and a cathode, and it may have, taking into account the nature of the materials which compose it, a certain mechanical flexibility. According to different embodiments, the emissive part 14 of the OLED diode can îo comprise one or more distinct illuminating surfaces. The connection part 16 is made of an insulating material, mechanically more rigid, and for example, and without limitation, a glass or a polymer resin. According to the embodiment more particularly illustrated in the figures, it is in the form of a substantially parallelepiped plate from one of the long sides of which extends the emissive part 14 of the OLED diode. In more detail, with reference to FIG. 2 in particular, the emissive part 14 of the OLED diode extends substantially in the same plane the connection part 16 from a first large side 18 of the plate forming said connection part, substantially at
    0 center of this first large side so that shoulder edges 20 are arranged on either side of the emissive part.
    The support module 10, visible in FIGS. 2 and 3 in a first embodiment, comprises a bottom wall 22 in the form, according to the embodiment illustrated by the figures, of a substantially rectangular plate whose dimensions are substantially identical to those of the connection part 16 of the OLED diode.
    The support module 10 further comprises a retaining frame 24 at least partially bordering the bottom wall 22. This retaining frame 24 extends substantially perpendicularly the bottom wall 22 in
    0 thus defining a housing 26 capable of receiving the connection part
    16. It is understood that the retaining frame 24 keeps the plate forming the connection part 16 of the OLED diode inside the housing 26, in particular to prevent the OLED diode from falling under the effect of gravity.
    According to the embodiment more particularly illustrated in Figures 2 and 3, this retaining frame consists of a set of first side walls 28 arranged parallel on the short sides of the bottom wall 22 and two stops 30 extending substantially perpendicularly one end side walls approaching one another, so as to narrow the passage between the first side walls.
    îo More precisely, the holding means are defined and arranged in such a way that, when the connection part 16 of the OLED diode is received against the bottom wall 22 in the housing 26, the stops 30 form a stop against the thickness the long side of the plate forming said connection part 16, while the first side walls 28 form an abutment against the thickness of the short side of the plate forming said connection part
    16.
    The set of side walls and stops thus defines a form of holding frame in which the connection part 16 of the OLED diode 12 is received and held, it being understood that here no wall is necessary
    0 opposite the stops 30 due to the vertical arrangement of the organic light-emitting diodes 12.
    An opening 32 is defined between the two stops 30 to allow passage for the OLED diode. Thus, in the assembled position visible in particular in FIG. 3, the connection part 16 can be housed in the housing of the support module while the emissive part 14 can extend outside the support module to participate in the function of lighting and / or signaling. The stops 30 cooperate with the shoulder edges 20 of the connection part 16 of the OLED diode.
    The support module 10 may also include elements making it possible to facilitate the engagement and the positioning of the connection plate 16 of the OLED diode within the housing, and for example, as it is visible in FIG. 2 , a pin 34 which projects from the bottom wall 22 so as to be able to cooperate with a complementary shape, here a bore 36, defined in the thickness of the plate forming the connection part 6.
    When the connection part 16 of the OLED diode is in place in the support module 10, an electrical contact should be made between these two elements. This is done in particular by the presence of conductive pads 38 attached to the bottom wall 22 forming part of the housing 26 of the connection portion 16. In the schematic example illustrated in FIG. 2, two first conductive pads are shown 38 in the form of substantially circular parts, and second electrical pads of equivalent shape are arranged on the connection part so that, when the OLED diode is mounted on the support module, these different electrical connectors are arranged one against the other others.
    It is understood that these first conductive pads 38 are connected by electrical tracks, not shown here, to a connector capable of cooperating with a connector complementary to the electrical device of the vehicle to make the electrical connection of the latter to a power supply device.
    0 electric and / or piloting of the lighting and / or signaling assembly of the vehicle.
    In order to ensure electrical contact between the first 38 and second conductive pads, the diode and its connection part 16 should be pressed against the bottom wall of the support module, and it is necessary to maintain this position. The holding means described above make it possible to avoid movement of the diode in directions perpendicular to the direction in which the connection part is pressed against the bottom wall, and an additional fixing means is provided to prevent movement of the diode in a direction opposite to the direction along
    0 which the connection part is pressed against the bottom wall.
    ίο
    These complementary fixing means may advantageously take the form of a bonding zone arranged between the bottom wall and the opposite face of the connection part of the diode. A bonding zone 40 can be provided separate from the first conductive pads 38, as illustrated in FIG. 2.
    In a variant not shown, these additional fixing means may consist of a protective cover covering the housing when the connection part of the OLED diode is housed there. In this case, the conductive pads could be made on an inner face of the cover, instead of being provided on the bottom wall of the support module.
    According to the invention, it is notable that at least part of the support module 10 is made of a transparent or translucent material, and that this transparent or translucent part is chosen from among the elements not covered by the OLED diode when the latter is supported by the support module.
    In particular, in the embodiment illustrated in FIG. 1, the first side walls 28 and the stops 30 which extend them, which form the frame for holding the diode in the support module, are each
    0 made of a transparent or translucent material, so that this holding frame is not visible, both when the diode is on or off, so that the outside observer has the visual impression that the diode floats without being held by a support medium.
    It is understood that the support module 10 can be entirely formed by a transparent or translucent material, or else, in an advantageous embodiment in terms of cost of the materials, that it is formed by two separate materials. In this case, we will be able to apply on the one hand a standard opaque material for all the parts of the support module hidden by the diode when the latter is housed in the support module, and
    0 in particular the bottom wall of the housing or the base of the support module, and on the other hand the transparent or translucent material for your exposed parts, and in particular your walls and stops forming the retaining frame and the first pin used for indexing of the connection part of the diode. We can also choose two materials with a different degree of transparency from one part to another of the support module, with a first translucent material and a second transparent material.
    The transparent or translucent material may, by way of example, consist of polycarbonate (PC) or polymethyl methacrylate (PMMA), it being understood that this choice is not exhaustive and limiting, since the chosen material is present at the both a transparent or translucent character and sufficient rigidity properties to maintain and / or index the connection part in the support module.
    In Figure 3, there is illustrated the assembled position in which the connection portion 16 of the diode is pressed against the bottom wall 22 of the corresponding housing 26. An outside observer, represented schematically in this figure, is likely to see, when the diode is not lit, both the assembly of the OLED diode 12, the retaining frame of the support module arranged around the diode and indexing pin arranged in the center of the connection part of the diode. The present invention
    0 the advantage of making all the elements likely to be seen by the outside observer, other than the OLED diode, transparent or translucent.
    We will now describe a second embodiment, with reference to FIG. 4, of a support module capable of receiving an OLED diode and comprising at least one transparent or translucent part. Again, the diode holding frame is made of a transparent or translucent material.
    The support module of this second embodiment differs in particular from what has been described previously in that the retaining frame projecting from the bottom wall 22 is limited to the presence of
    0 stops 30. Only these stops are then to be provided in transparent or translucent material to make invisible or almost invisible all of the elements arranged around the diode when the latter is pressed into the housing of the support module.
    No first side wall is provided on the short sides of the bottom wall, so that the number of elements to be made transparent or translucent is limited, which can reduce costs.
    In this context, in order to maintain the connection part in position in the housing, an enlarged bonding zone 40 is provided and a conductive adhesive is used, that is to say loaded with metallic materials, îo in order to perform in the same area the bonding function and the conductive pad function.
    The glue could be replaced by any adhesive layer, it being understood that it is advantageous in the context of the present invention for the connection part of the diode to be fixed in the housing of the support module without any visible fixing means, and for example fixing screws, which would reduce the visual effect that the diode seems to float without being held by the support module.
    Furthermore, the support module in this second embodiment has a bottom wall extended by a support tab 44, against
    0 which carries the emissive part of the OLED diode when it is in place in the support module. The support tab 44 extends in the plane of the bottom wall 22 beyond the stops 30 forming the retaining frame around the bottom wall. A wall is thus defined which makes it possible to reduce the cantilever surface of the diode, which makes it possible to limit the vibrations of the diode during the running of the vehicle.
    In each of these embodiments, the invention thus achieves its goal, by proposing a light module which implements at least one organic light-emitting diode the maintenance of which in position by a support module makes it possible to generate a visual effect according to which this diode is floating, without visible mechanical support, by the implementation of all or part of the support module in transparent or translucent material.
    It should however be noted that the invention cannot be reduced to the means and configurations described and illustrated, but that it also applies to any equivalent means or configurations and to any combination of such means. By way of example, the shapes of the plate forming the connection part of the OLED diode and of the support module described here are indicative, and the invention also extends to any other form of connection part and support, from when the support module has walls forming a stop at the positioning of the diode and these positioning stops are made of a translucent or transparent material.
