    The invention relates to the field of lighting and signaling devices for a motor vehicle.
    In known manner, this type of device tends to become more complex because of the increasing number of functions that these devices are intended to implement. Among these functions, there is included the implementation of scrolling direction indicator directions. Moreover, there is a need to give these devices an aesthetic character which contributes in particular to define the overall appearance, or "visual signature" of the vehicle considered, and which differentiates it from other vehicles. For example, this aesthetic character can take the form of a device whose emission surface extends in three dimensions.
    In this context, the invention aims to present a light device for a motor vehicle that allows the definition of a particular visual signature for this vehicle while having an optimized design, reliability and compactness. For this purpose, the invention proposes a light device for a motor vehicle, the light device comprising a first module comprising a first organic light-emitting diode, a second module comprising a second organic light-emitting diode and a control module arranged to control the first and second electrodes. modules so that the light device performs a scrolling direction indicator function.
    Where appropriate, each organic light-emitting diode may be able to emit amber light.
    Advantageously, the control module is arranged to control the first and second modules so that the organic light-emitting diodes are sequentially in an active configuration. By active configuration is meant a configuration of the organic light-emitting diode into which light emitted by said diode exits the device to participate in said scrolling direction indicator function.
    According to one embodiment of the invention, each organic light-emitting diode is movably mounted, for example in rotation, in the light device. Advantageously, each module comprises an actuator associated with the organic light-emitting diode of said module for selectively bringing said organic light-emitting diode into a rest position, in which the emission face of the organic light-emitting diode is masked so that little or no light emitted by the organic light-emitting diode can exit from the light device, and in an active position, in which the emission face of the organic light-emitting diode is visible so that light emitted by the organic light-emitting diode can exit. the light device to participate in said deflecting direction indicator function. If necessary, the control module is arranged to control the actuators so as to sequentially bring each organic light-emitting diode into its active position, which thus forms the active configuration.
    According to another embodiment of the invention, the control module is arranged to control the ignition of the first and second modules so as to achieve a sequential ignition of the first and second organic light emitting diodes. For example, the control module is arranged to control the supply of each organic light-emitting diode so as to turn on or off this diode. In this case, the active configuration of this diode is when it is lit.
    Advantageously, the first and second modules are arranged in such a way that the first organic light-emitting diode is disposed towards the interior of the vehicle and the second organic light-emitting diode is disposed towards the outside of the vehicle, when the light device is mounted in the vehicle. motor vehicle. If necessary, the control module is arranged to turn on the first organic light-emitting diode before the second organic light-emitting diode. Optionally, the control module may be arranged so that the first organic light-emitting diode remains on during the ignition of the second organic light-emitting diode. The control module thus implements a sequential and progressive ignition of the organic light-emitting diodes from the inside to the outside of the vehicle.
    According to one embodiment of the invention, the first organic light-emitting diode is distinct from the second organic light-emitting diode. Where appropriate, each organic electroluminescent diode has a pair of electrodes, these pairs of electrodes being distinct from one diode to the other.
    In a variant, the first and second organic light-emitting diodes may comprise a common electrode. Where appropriate, each organic light-emitting diode forms a distinct segment of a single global organic light-emitting diode of the light device. For example, said global organic light-emitting diode has a first face comprising an electrode, for example an anode, which continues along its entire length, a second segmented surface comprising an alternation of a plurality of second electrodes and electrically insulating strips, and a layer organic material capable of emitting light disposed between the first and second faces. Each segment formed by a portion of the first electrode, a portion of the organic material layer and a second electrode thus forms one of said organic light emitting diodes. Where appropriate, the first electrode may be able to pass light, for example by being transparent, and form a light-emitting face of each organic light-emitting diode and each second electrode forms an installation face of each diode electroluminescent organic. Alternatively, the first face may also be segmented.
    In one embodiment of the invention, the luminous device comprises at least one support comprising a mounting face extending in three mutually perpendicular directions, and at least one of the organic light-emitting diodes is mounted on the face of mounting of the support.
    The mounting face thus has a surface extending in three dimensions. Advantageously, this mounting face may have the shape of a developable surface. Where appropriate, said organic electroluminescent diode has an installation face and a light emitting face opposite the installation face, the organic light-emitting diode being mounted on the support via its installation face. The organic electroluminescent diode may be arranged so that it is able to emit light via its light-emitting face in a general direction substantially parallel to a normal of the mounting face.
    Advantageously, the organic electroluminescent diode is flexible. Preferably, the organic electroluminescent diode is mounted on the mounting face so as to have a shape identical to that of the mounting face. Where appropriate, the organic light-emitting diode is mounted so that no play is present between its installation face of said diode and the mounting face of the support. In other words, the diode is mounted on the support without play.
    In one embodiment of the invention, the organic light-emitting diode is bonded to the mounting face, in particular via its installation face. If desired, the light-emitting diode can be glued to the mounting face using a double-sided adhesive tape. Alternatively, the organic light emitting diode can be glued with an adhesive.
    Advantageously, the device may comprise a positioning pin fixed to the organic light-emitting diode and inserted into an orifice of the support. The positioning pin may for example be glued to the installation face of the diode.
    If desired, the positioning pin may be provided with a fastener, for example a clip, from the organic electroluminescent diode to the support. If necessary, the device may be devoid of adhesive connecting the diode to the support.
    In another embodiment of the invention, the organic light-emitting diode is made directly on the support. In this case, the device can be devoid of any means of fixing the organic light-emitting diode to the support. The organic light-emitting diode may for example be produced by a method of evaporation under vacuum on the support, including steps of metallization of the support and deposits of organic material emitting light and electrode, or by a method of printing under the support. The subject of the invention is also a method for controlling a light device according to the invention, characterized in that it comprises the following steps: the first module is activated so that light emitted by the first organic light-emitting diode the light device; after the activation of the first module, the second module is activated so that light emitted by the second organic light-emitting diode leaves the light device. The invention will be better understood on reading the detailed description which follows, given solely by way of example and with reference to the appended figures, in which:
    Figure 1 is a schematic and partial illustration of a light device according to the invention;
    Figures 2a to 2f are views of the light device of Figure 1 implementing a method according to the invention;
    Figure 3 is a schematic and partial illustration of a light device according to another embodiment of the invention.
    Figure 4 illustrates an exploded view of the light device of Figure 1 according to a first embodiment of the invention;
    Figure 5 is a sectional view of the light device of Figure 1 according to a second embodiment; and
    Figure 6 is a sectional view of the light device of Figure 1 according to a third embodiment.
    Figure 1 illustrates a light device 1 according to the invention.
    The light device 1 comprises a global organic light-emitting diode or OLED 2. The OLED 2 has a first reflective face 21 made of aluminum forming an anode 21 of the OLED 2. The anode 21 extends continuously over any the length of the OLED 2. The OLED 2 comprises a second face 22. The second face 22 is segmented, namely that it comprises an alternation of cathodes 221 transparent and made of indium-tin oxide or ITO and of insulating strips 222 electrically. OLED 2 finally comprises a layer 23 formed of a superposition of sub-layers of organic material able to emit amber-colored light when electrically powered. The layer 23 is disposed between the first and second faces 21 and 22 so that part of the light it emits passes through the cathode 221 and the other part of this light is reflected by the anode 21 and also passes through the cathode 221.
    Each superposition of a cathode 221, a portion of the layer 23 and a part of the anode 21 located opposite this cathode 221 forms a segment of the global OLED 2 which is selectively activatable. . This segment thus itself forms an OLED whose light emitting face is its transparent cathode 221 and whose anode 21 is common to the other segments. It goes without saying that the anode 21 could also be segmented.
    The light device thus comprises five modules 31 to 35, each formed by one of the segments of the global OLED 2.
    The light device further comprises a control module 4 connected on the one hand to each cathode 221 of the modules 31 to 35 by bits 41 to 45 and to the common anode 21 by a wire 46. The control module 4 can thus selectively supplying each of the modules 31 to 35, via the wires 41 to 45, so as to selectively switch on the OLEDs of these modules.
    The control module 4 is here arranged in the form of a microcontroller comprising a memory unit (not shown) in which is stored a sequential ignition control of the modules 31 to 35 to achieve a running direction indicator.
    FIG. 2a shows the device 1 when all the OLEDs of the modules 31 to 35 are off and in FIGS. 2b to 2f the said ignition sequence for producing the traveling direction indicator.
    The modules 31 to 35 are arranged in the device 1 so that the OLED of the first module 31 is disposed towards the inside of the vehicle and the OLED of the last module 35 is disposed towards the outside of the vehicle, when the luminous device 1 is mounted in a motor vehicle.
    When the control module receives a command to initiate the sequence for producing the running direction indicator, the control module 4 first supplies the module 31 to turn on the OLED of this module 31 (FIG. 2b). . After a lapse of 200 ms or less, the control module 4 supplies the module 32 to turn on the first organic light-emitting diode of this module 32, while continuing to supply the module 31 (FIG. 2c). The control module 4 thus continues to sequentially light up the OLEDs of the following modules while keeping the OLEDs of the preceding modules lit (FIGS. 2d and 2e), until all the OLEDs of the modules 31 to 35 are lit (FIG. 2f ). The control module 4 thus implements a sequential and progressive ignition of the OLEDs from the inside to the outside of the vehicle. In this case, the apparent light surface formed by the set of all OLEDs on is continuous. In addition, once all these OLEDs are lit, the control module 4 simultaneously interrupts the power supply of all the OLEDs, then repeats the sequence until the reception of a command to interrupt the sequence, and thus realizes an indicator regulatory direction, for example as defined in the UNECE Regulation No. 6 on direction indicators, paragraph §5.6.
    FIG. 3 shows a light device 5 according to another embodiment of the invention. The light device 5 comprises five light modules 51 to 55, each comprising an organic light emitting diode OLED 61 to 65, the OLEDs 61 to 65 being distinct from each other.
    Each OLED 61 to 65 is rotatably mounted about an axis 71 to 75 in the light device 5 and each module comprises an actuator 81 to 85 associated with the OLED 61 to 65 of said module to drive the axis 71 to 75 and selectively bring said OLED into a rest position (P) and into an active position (A). The OLED 65 is represented in its rest position (P) where its emission face is masked so that little or no light emitted by it can emerge from the light device 1. The OLEDs 61 to 64 are represented in an active position, in which their emission face is visible so that the light they emit can exit the light device 1 to participate in said scrolling direction indicator function.
    The light device 1 comprises a control module 9 which is arranged to control the actuators 71 to 75 so as to sequentially bring each organic light-emitting diode into its active position.
    FIG. 4 shows an exploded view of the light device 1 of FIG. 1, in which the segmentation of the global OLED 2 is not shown.
    In addition to the global OLED 2 and the control module 4, the light device 1 comprises a support 11 comprising a mounting face 111 extending in three perpendicular directions X, Y and Z in pairs to form a developable surface. The global OLED 2 is mounted on the mounting face 111 of the support 11.
    In the example shown, the mounting face 111 has a cylindrical shape, but the invention is not limited to that only form of developable surface. OLED 2 has an installation face 21 formed by the anode and a light-emitting face formed by the face 22, opposite the installation face 21. The OLED 2 is flexible and is mounted on the mounting face 111 so as to conform to the profile of this mounting face 111 and thus have a shape identical to that of this mounting face 111. In addition, because of the developable form of the mounting face 111, the OLED 2 is mounted on the support 11 without clearance. The OLED 2 is glued to the mounting face 111 by means of a double-sided adhesive film 12. In addition, the control module 4 is also mounted on the mounting face 111 using a double-sided film 13.
    FIG. 5 shows a variant of the embodiment of FIG. 4. The references of the identical elements between these two embodiments will be retained.
    The device 1 comprises a positioning pin 14 fixed in advance to the installation face 21 of 1OLED 2 by the double-sided adhesive film 12. The pin 14 is inserted into an orifice 15 of the support 11 so as to position the OLED 2 in a predetermined position on this support 11.
    FIG. 6 shows another variant of the embodiment of FIG. 4. The references of the identical elements between these two embodiments will be retained.
    In this embodiment, the positioning pin 14 is provided with a clip 16 allowing, in addition to its positioning function, to secure the OLED 2 to the support 11. This method of attachment thus makes it possible to eliminate the double adhesive film. -faces of Figure 4 connecting the OLED 2 to the support 11. The invention is of course not limited to the embodiments shown and other embodiments may be clearly apparent to those skilled in the art without departing from the scope the present invention.
