    LIGHT MODULE WITH INTEGRATED STEERING DEVICE
    The present invention relates to the field of light modules intended to be mounted in vehicle light devices.
    More particularly, the invention relates to autonomous light modules, in particular as regards the control of their light source (s).
    It is known in vehicle light devices to arrange one or more light modules. Depending on the light beam to be produced, these modules are switched off or on, with a determined intensity.
    When these light modules are equipped with a light source whose power must be adjusted and controlled to have the required intensity, as in the case of a light-emitting diode, the light device is equipped with a specific control device arranged to control the supply of the light source.
    In known manner, the control device is separated from the light modules and arranged away from them, inside the housing of the vehicle light device. A power supply cable electrically connects the control device to a connector of the light module. The control device is itself connected to the vehicle's power supply.
    When there are several light modules in the vehicle, there are therefore as many power supply cables as there are light modules, each of these cables connecting a light module corresponding to the control device. In addition, the control device includes many components to manage all of these light modules. It therefore heats up a lot. It is therefore also better to place it away from the light modules.
    It follows that a significant amount of electrical cable length is used, which increases the cost and the weight of the light device.
    The technical problem that the invention aims to solve is therefore how to reduce the cost and the weight of a light device comprising several light modules whose light sources are controlled by a control device.
    Going against the conventional solution of a single remote control device for light modules, the inventors of the present invention realized that this problem could be resolved on the scale of the light modules themselves, by eliminating the single control device, by arranging a control device by light module and integrating this control device into the light module itself.
    To this end, a first object of the invention is a light module intended to be mounted in a vehicle light device, said light module comprising:
    - a support for an electroluminescent light source,
    - a control device fixed on said support and arranged so as to control the light-emitting light source.
    Thus, several light modules according to the first object of the invention can be arranged in a light device, without the latter needing to integrate a control device common to these modules.
    A single electrical harness bringing power to the vehicle battery can be arranged up to all of the modules and multiply as many power cables as close as possible to these.
    As a result, less length of electrical power cables should be used. These light modules therefore make it possible to produce a lighter and less expensive light device.
    In addition, each control device comprising fewer electronic components, in particular electronic components specifically sized to meet the needs of the light source as accurately as possible, it heats less than a single device, and can therefore be integrated into the light module without risking to degrade it and / or to disturb the operation of the light-emitting light source.
    The power supply cables carry so-called strong currents, and are therefore liable to generate electromagnetic disturbances. They should therefore preferably be shielded. By reducing the total length of cable used, protection against these electromagnetic fields is easier to achieve.
    In addition, such a module becomes an autonomous light emission assembly. Thus, the module can be made separately with its electroluminescent light source and the control device which is specifically dedicated to it, to then be mounted in the light device. The light module is then ready to be connected and used directly in the light device without a lot of settings, or even without any settings, of the control device. The assembly of the light device is thus simplified.
    Likewise, the light module can be easily removed from the light device in the event of failure of the control device or of the corresponding electroluminescent light source, for example to change this module. The new module is then simply assembled and connected, since it incorporates the control device specifically adapted to its light-emitting light source.
    As a result, the inventors have realized that such a light module could therefore also be arranged in a light device with a single light module and according to the first object of the invention. Indeed, such a light device also benefits from the advantages linked to the autonomy of such a light module, in particular for the assembly of the light device, or for the replacement of the light module.
    In the present application, a control device is a device for converting an electrical supply from a vehicle electrical supply network into an electrical supply suitable for achieving a desired light function, and optionally for providing said power supply adapted to an electroluminescent light source for the achievement of said desired light function. It can also include a diagnostic function. This type of piloting device is commonly called “Driver” (meaning pilot in English) in the field of lighting.
    In the present application, an electroluminescent light source is a light source implementing electroluminescence. Electroluminescence is an optical and electrical phenomenon during which a material emits light in response to an electric current passing through it, or to a strong electric field. This is to be distinguished from the emission of light due to the temperature (incandescence) or the action of chemicals (chemiluminescence). Such an electroluminescent light source is also designated in the field of lighting by the English terms solid state lightsource.
    The light module according to the invention can optionally include one or more of the following characteristics:
    - The support is made of a thermally conductive material; this also ensures the cooling function of the electroluminescent light source;
    the support is made of metal, in particular aluminum or an aluminum alloy; this also ensures the cooling function of the electroluminescent light source;
    - the light emitting light source comprises a light emitting element comprising a semiconductor material;
    - the light emitting light source is a light emitting diode; the present invention is particularly advantageous in such a case because the light-emitting diodes must be driven constantly;
    - The light emitting light source is fixed in thermal contact with said support; this allows this light-emitting light source to be cooled more efficiently, in particular when the latter comprises a semiconductor material, in particular in the case of a light-emitting diode;
    - The light module includes a metal enclosure fixed on the support and around the control device, so as to form a Faraday cage around it;
    the support comprises a first face and a second face, these two faces being transverse with respect to each other, these two faces defining a housing space inside which is housed the electroluminescent light source and the device piloting; this makes it possible to produce a compact module;
    - the electroluminescent light source is fixed on the first face and the control device is fixed on the second face; this makes it possible to arrange the control device more distant from the light-emitting light source;
    - the light module comprises a connection cable connecting and connecting the control device to the electroluminescent light source;
    - according to the previous paragraph, the connection cable can be laid on the support between the control device and the light-emitting light source; this makes it possible to avoid vibrations of this cable and therefore to degrade its connections;
    - the electroluminescent light source and the control device are fixed on the first face; this makes it possible to bring the electroluminescent light source and its control device closer together, and therefore reduce the energy losses between the two;
    - according to the preceding paragraph, the light module comprises a printed circuit fixed on said first face, the control device being fixed on the printed circuit, the printed circuit comprising electrical tracks connected to the control device and to the light-emitting light source , so as to allow the control device to supply and control the light-emitting light source; this simplifies the electrical connection between the electroluminescent light source and its control device because there is no longer a wired connection between the latter;
    the support is a plate comprising a first part comprising the first face and a second part comprising the second face, the shape of the plate being arranged so that said first part and said second part are transverse with respect to the other ; it is a form of support that is simple to produce; in particular, the support can be a folded or stamped metal plate, a fold and / or a portion of a curved plate connecting, for example, the first and second parts;
    - The plate is a heat sink in thermal contact with the electroluminescent light source and / or the control device; the double support and heat dissipation function is thus easily achieved;
    - The plate includes curved edges forming fins; this improves heat dissipation;
    - The first part includes bosses on the first face and / or on a face opposite this first face; this allows the plate to be engaged under stress in housings of a light device, in which this module is intended to be mounted, in particular slides; in addition to an adjustment, this reduces vibrations in the light device; it is all the more effective when the light-emitting light source is fixed on this first face;
    - The first part includes tabs having transverse sections; this allows the light module to be mounted in rails;
    - the bosses are formed on the tongues;
    - the support includes:
    o a third face arranged on said first part opposite said first face, and o a fourth face arranged on said second part opposite said second face, the light module comprising a connector fixed on the third or fourth face, depending on whether the control device is fixed respectively to the first or the second face, said connector being electrically connected to the control device through the plate; this makes it possible to make the connection outside the space where the electroluminescent light source is housed; this avoids cluttering this area and makes it easier to disconnect the module before removing the light device;
    the light module comprises a printed circuit fixed on said first face, in which the light-emitting light source is fixed on the support away from the printed circuit, the light-emitting light source being electrically connected to said electrical tracks by pins, conductive strips, or soldered wires; it is a simple form of connection of a light-emitting light source, in particular of a light-emitting diode.
    The invention also relates to a vehicle light device comprising at least one light module according to the invention.
    This vehicle light device can be:
    - a device lighting the road, especially a projector or a anti-fog ; the present invention East particularly suited to these device lighting who
    use high light intensities;
    - a signal light, in particular; a stop light, a daytime running light, a night position light, a direction indicator;
    - an interior lighting device, namely the interior of the passenger compartment of a vehicle, in particular: a ceiling lamp or a wall lamp.
    The light module according to the invention can optionally include one or more of the following characteristics:
    the light device comprises at least one shaping optic and reversible mounting means for the corresponding light module with respect to the shaping optic, so that the shaping optic receives the light rays emitted by the electroluminescent light source of this light module and sends them out of the light device; this makes it possible to mount and dismount the or each light module of the light device, to change both the electroluminescent light source and the associated control device;
    - The mounting means comprise slides and tabs, the light module being mounted in the light device by sliding these tabs in these slides; these are precise means for ensuring reversible mounting and positioning;
    - the light module, in particular the support, comprises the tongues and the slides are fixed to the shaping optics;
    - the light module, in particular the support, comprises the slides and the tongues are fixed to the shaping optics;
    - the mounting means comprise one or more fixing screws; this ensures a strong reversible attachment;
    this allows easy assembly and replacement of the light module; the latter may include tabs arranged
    - These slides have a bottom so that the tongues are pressed against this bottom; the latter achieves a stop, so that positioning with respect to the shaping optics is achieved by sliding the module fully into the slides;
    - the light device comprises at least one reflector comprising:
    o a reflecting face arranged so as to review the light rays emitted by the electroluminescent light source of the light module, o a face opposite to the reflecting face, called the inactive face of the reflector, said light module and the reflector being arranged so that that said second face of the support is opposite said inactive face and the control device is between said inactive face and said second face of the support; thus forming a space for housing the control device;
    the reflector comprises metal and the support is made of metal, so that the reflector, the part of the support carrying the first face and the part of the support carrying the second face together form a Faraday cage;
    - The light device comprises several light modules according to the invention;
    a single electric beam is connected to a first of the light modules, the other light modules being electrically connected to the electric beam on this first light module; cable lengths are further reduced;
    - the light modules are connected together, the control device of a first of these light modules, called the first control device, being arranged so as to transmit control signals to the control devices of the other light modules, as a function of a received control signal corresponding to a given photometry, so that the light modules together form a light beam having the given photometry; this makes it easier to synchronize the light modules with each other.
    According to the request, a shaping optic deflects the light rays emitted by the corresponding electroluminescent light source of the device so as to give the beam of the light device given photometric characteristics, in particular of a beam of road lighting. The shaping optics may include a reflector, a combination of lenses, a combination of reflectors, or a combination of lenses and reflectors.
    The invention also relates to a vehicle comprising a light device according to the invention, in particular connected to the electrical supply of the vehicle.
    Unless otherwise indicated, the terms "front", "rear", "lower", "upper", "side", "transverse" refer to the direction of light emission outside the corresponding light device.
    Other characteristics and advantages of the invention will appear on reading the detailed description of the following nonlimiting examples, for the understanding of which reference will be made to the appended drawings, among which:

    FIG. 7 is a perspective view from the front and from below of a light module according to the present invention according to a second embodiment.
    According to the embodiment illustrated in FIG. 1, the light module 10 comprises a support 20. This support 20 carries an electroluminescent light source 11, as well as a control device 12 intended to control the supply of this light source light-emitting 11.
    In this example, the support is formed by a stamped metal plate 20. This is for example formed from aluminum. Alternatively, the plate can be formed by injection into a mold of a polymer material, this polymer material comprising fillers so as to be thermally conductive. The aluminum construction allows the use of electroluminescent light sources generating a lot of heat, such as those used in road lighting.
    In this example, this light module 10 is intended to produce part of a light beam for road lighting. The light emitting light source is a light emitting diode 11, also called LED or LED.
    This light module 10 forms an autonomous module capable of being removed and reassembled from a light device 1, such as that illustrated in FIGS. 3 and 4.
    This plate 20 is stamped so as to form two main parts: a first part 21 and a second part 22. These main parts 21, 22 are generally planar, that is to say that each plate mainly extends along a plane.
    These two main parts 21, 22 are here connected to each other by a curved portion 29 of the plate 20, this curved portion 29 being able to be produced by folding.
    The first part 21 in this example is arranged so as to be mounted horizontally in the light device 1. It is therefore hereinafter called the horizontal part
    21.
    The second part in this example is arranged so as to be mounted vertically in the light device 1, extending downwards from the curved portion 29. It is therefore hereinafter called the vertical part 22.
    The electroluminescent light source 11 being here an LED, it comprises a semiconductor material which, when crossed by an electric current, generates light rays. In such a case, this semiconductor material gives off a lot of heat. Also, it is useful to dissipate its heat so that the LED 11 does not lose too much in terms of performance. For this, the LED 11 is mounted in thermal contact against the horizontal part 21. For example, the LED 11 is fixed by means of a thermally conductive adhesive.
    The LED 11 is here supplied electrically via a printed circuit 15, in this example a printed circuit board.
    The printed circuit 15 is mounted on said horizontal part 21. The control device 12 is here mounted on the printed circuit 15 and therefore on said horizontal part 21. Thus, the connection between the LED 11 and the control device 12 is made via electronic tracks (not shown) of the printed circuit 15.
    In the example illustrated, in particular in FIGS. 1 and 5, the LED 11 is connected to the tracks of the printed circuit 15 by metal blades 17 connecting on one side to the LED 11 and on the other to the printed circuit 15, in particular by welding.
    The control device 12 includes electronic components 14 which also give off heat. However, this control device 12 being arranged so as to drive the LED 11 of this single light module 10, it comprises much fewer electrical components than a control device driving several light modules.
    Furthermore, as this control device 12 is directly associated with its LED 11, it does not include electronic identification components responsible for identifying the LEDs to which it is connected.
    There is therefore much less heat given off at the level of such a control device 12, than at the level of a control device conventionally used to control several light modules.
    According to the invention, the control device 12 can be in thermal contact with said horizontal part 21 via the printed circuit 15, in particular by thermal tracks (not shown).
    Therefore, the support 20 allows the heat to be removed from both the LED 11 and the control device 12.
    Said vertical part 22 makes it possible to drain more heat to cool the LED 11 and the control device 12.
    In order to reinforce the heat dissipation by this support 20, the plate forming this support is stamped so as to have fins 37, both at its horizontal part 21 and at its vertical part 22.
    As can be seen in Figures 1 and 2, the horizontal part 21 and the vertical part 22 are transverse to each other and thus define a volume between them forming a housing space 28, in which is placed the control device 12 and the electroluminescent light source 11.
    The faces of said horizontal part 21 and of said vertical part 22 which are turned towards the housing space 28, respectively form a first face 23 and a second face 24.
    In this example where the support is formed by a plate 20, said horizontal part 21 and said vertical part 22 respectively comprise a third face 25 and a fourth face 26 arranged opposite the first face 23 and the second face 24 respectively .
    In this example, the LED 11 as well as the printed circuit 15 are fixed on said first face 23.
    According to the invention, the light module 10 can, as illustrated in FIGS. 3 to 5, be mounted with the LED emitting downwards. Thus, the LED 11 and its control device 12 are arranged below the horizontal part 21 and in front of the vertical part 22.
    According to the invention, and as in this example, the portion of the support connecting these two main parts 21, 22, namely here the curved portion 29, forms with these main parts 21, 22, a delimitation of this housing space 28.
    This housing space 28 makes it possible to create an electromagnetically isolated space, the support 20 being made of metal. In particular, said horizontal part 21 and said vertical part 22 provide shielding, in this example respectively upwards and rearwards of the LED 11 and its control device 12. The electromagnetic compatibility (EMC) of this light module 11 with its environment is thus improved.
    Here, the connection of the control device 12 to the electrical supply is made via a connector 16 of the light module 10. This connector 16 is connected to the control device 12 through a through hole 38 of said horizontal part 21.
    As in this example, the printed circuit 15 at least partially covers the through hole 38 on the side of said first face 23. The printed circuit comprises, on its face oriented towards this first face 23, contact points 18, visible in FIG. 3. These contact points 18 are connected to the conductive elements of the connector 16 of the light module at the level of the through hole. The inlet of this connector 16 is arranged on the other side of said horizontal part 21, therefore, here, above the third face 25.
    In this arrangement, the connector 16 of the light module therefore does not clutter the interior of the housing space 28 and the connection is made outside this housing space 28.
    When the light module 10 is mounted in the light device 1, as in FIG. 3, it is easy to connect the light module 10 from the rear, in particular by means of a simple cable connector 40 of a power cable. 41 connected to the vehicle battery, as can be seen in FIG. 6.
    According to the invention, and as illustrated in FIG. 6, the cable connector 40 can be a male plug which is plugged inside the connector 16 of the module 10, the latter connector 16 forming a female plug.
    Said horizontal part 21 comprises lateral tabs 34 comprising a front edge 36.
    In this example, each of these tongues 34 comprises bosses 39.
    As in this example, the bosses 39 the bosses can be formed on said third face 25.
    In this example, as the support is produced by stamping the plate, the bosses 39 are seen in hollow on said first face 23.
    These bosses 39 and these tongues 34 form means for mounting the light module 10 in the light device 1 illustrated in FIG. 3.
    The light module 10 according to the invention is mounted with respect to shaping optics, in this example a reflector 30, so as to participate in the production of the light beam emitted by the light device 1.
    In this example, the light device 1 comprises a housing 2, shown diagrammatically in FIG. 3 by a double line. This box 2 is closed at the front thereof by a closing glass 3, also symbolized by a double line in FIG. 3. Inside this box 2 is arranged a set of light modules 10, 10 ′, 10 '' according to the invention.
    In this example, the light device is a projector 1 and there are three light modules to form its different light beams. In the center, we can observe the light module 10 of Figure 1, hereinafter the first light module, and on either side of it a second light module 10 'and a second light module 10' ', which are light modules according to the invention.
    The second light module 10 'and the third light module 10' 'can be identical to the first light module 10.
    Alternatively, the second light module 10 'and the third light module 10' 'can be different. For example, they can differ from the first light module 10 by the characteristics of the LED 11, the characteristics of the printed circuit 15, or of the characteristics of the control device 12. In such a case, these light modules 10, 10 ′, 10 ′ 'can include mechanical and / or visual polarizers so as to facilitate their positioning with the reflector 30, 30', 30 '' dedicated to them.
    According to the invention, and as in this example, the reflectors 30, 30 ', 30' 'of the projector 1 may have come integrally in one piece and form a plate 46 supporting all of the light modules 10, 10', 10 ''. In this case, the plate 46 therefore comprises portions forming the reflectors 30, 30 ', 30' ', as well as portions fixed relative to its reflectors.
    The light device 1 emits its light beam or beams generally in a longitudinal direction X so as to illuminate the road.
    The plate 46 comprises attachment points 45 to the housing 2 of the projector 1. These attachment points 45 are also arranged for some so as to be able to move the plate in height or laterally, thus making it possible to adjust the position of the beam d lighting on the road.
    The plate 46 includes slides 32, 32 'and 32' ', here formed integrally with the reflectors 30, 30',
    30' ' .
    According to the invention, as here, when the mounting means of the light modules 10, 10 ', 10' 'comprise slides 32, 32' and 32 '', these slides can be arranged so as to extend parallel to the longitudinal direction X. It is thus possible to mount each of the modules 10, 10 ', 10' 'by inserting the lateral tabs 34, 34', 34 '' inside these slides 32, 32 'and 32' ', therefore sliding the module 10, 10 ', 10' 'in a translational movement parallel to the direction X.
    As in the example illustrated, these slides 32, 32 'and 32' 'may include at the front a bottom 35, 35', 35 '' which forms a stop making it possible to stop this sliding.
    The slides 32, 32 'and 32' ', in particular their bottoms 35, 35', 35 '', are arranged so that when the corresponding light module 10, 10 ', 10' 'is in abutment against the bottoms 35, 35 ', 35' 'corresponding, the corresponding LED 11 is positioned relative to the reflector 30, 30', 30 '' corresponding so that the reflecting surface 30a of this reflector, located at the front of it ci, collects the majority of the rays rl, r2 emitted by the
    LED 11, or even all of these rays. Preferably, in such a case, the LED 11 is in a determined position according to which the reflecting surface 30a of the reflector 30 is arranged so as to reflect the rays rl, r2 emitted by the LED 11 according to a given photometry.
    For example, depending on the light modules 10, 10 ', 10' 'which are activated, the headlamp generates a dipped beam or a road beam, or even a motorway beam.
    The reflector 30, 30 ', 30' 'can be arranged so as to be at a certain distance from the slides 32, 32' and 32 '' so that the top of the reflector is at a distance 31 from the printed circuit 15, thus favoring sliding the light module 10, 10 ', 10' 'over the corresponding reflector.
    As can be seen in FIG. 3, said vertical part 22 can include positioning holes, in which studs are housed to improve positioning of the corresponding light module 10, 10 ′, 10 ″.
    To improve the fixing and reinforce it, the light device 1 can comprise, for each of the light modules, a screw 33, 33 ', 33' 'which screws the plate forming the support 20 onto the plate 46.
    In this example, the screw 33, 33 ', 33' 'is screwed onto said vertical part 22. This screw can be screwed in particular into drums (not shown) carried by a rear face 30b of the corresponding reflector 30.
    According to the invention, and as in the example illustrated, the housing space 28 is delimited at the front by the corresponding reflector 30, 30 ', 30' '. In particular, this housing space 28 is located between the front face 24 of said vertical part 22 and the inactive face 30b of the reflector 30, this inactive face 30b being the rear face of the reflector 30 situated opposite the reflecting face 30a receiving the light rays from LED 11.
    In such a case, when the reflector 30, 30 ', 30' 'comprises metal, for example when it comprises a reflecting surface 30a comprising a layer of aluminum or an aluminum alloy, in particular produced by aluminizing, in particular of a plastic core, this reflector 30, 30 ', 30' 'forms a shielding wall protecting the environment at the front of the LED 11 and its control device 12. This can in particular make it possible to form a Faraday cage more complete around the housing space 28, by means of said horizontal part 21, said vertical part 22 and the corresponding reflector 30, 30 ', 30' '.
    According to the invention, and as in the example illustrated, the light device can comprise vertical longitudinal separating walls 47 on the sides of, at least one of or each of each reflector 30, 30 ', 30' '. These separating walls 47 thus delimit the corresponding housing space 28 on the sides of the corresponding light module 10, 10 ′, 10.
    These separating walls 47 can comprise metal. For example, they may include a surface comprising a layer of aluminum or an aluminum alloy, in particular produced by aluminizing, in particular a plastic core. Thus, the separating walls 47 form a lateral shielding of the housing space 28, thus improving the EMC of the light device 1.
    In the example illustrated, the plate 46 comprises the separating walls 47. Those which are situated between the reflectors 30, 30 ′, 30 join them here longitudinally.
    According to the invention, these separating plates 47 can, as in the example illustrated, form portions of masks. The masks are aesthetic pieces intended to hide certain elements of the projector.
    To complete the Faraday cages around the housing spaces 28, the plate 46 may also include a horizontal wall, hereinafter called floor 48, arranged under the light modules 10, 10 ′, 10 ″ so as to form a shield against electromagnetic emissions propagating downwards.
    In order to reinforce the protection of the components 14 of the control device 12, but also to improve the EMC of the light device 1, the control device 12 can comprise an enclosure 13, surrounding the components 14, the enclosure possibly being, for example, directly fixed on the support 20, or on the printed circuit 15.
    The light device 1 in FIG. 3 does not require much wiring compared to conventional solutions. We can indeed bring the power supply as close as possible to the light modules 10, 10 ', 10' '. For example, the electrical power supply can be brought by a single electrical harness to an intermediate connector arranged at one of the light modules, intermediate cables then allowing the electrical power to be distributed between this intermediate connector and the various modules. 10, 10 ', 10' '.
    It is also possible to connect the light modules 10, 10 ', 10' 'in series.
    In FIG. 6, only the light modules 10 and 10 ′ have been illustrated. Here, the connection to the vehicle battery is made above and behind the first light module 10, via a first cable connector 40 of a first power cable 41. This first cable connector 40 is also connected, via a second power cable 42 to a second cable connector 40 ', which is connected to the connector 16' of the second light module
    10 '.
    These connections can be made either before mounting the light modules 10, 10 ', 10' 'in the light device 1, or after.
    According to the invention, the first light module 10 can comprise a control device 12 arranged so as to be able to send a control signal to the other light modules 10 ', 10' 'which are connected to it, via its cable connector 40 by the second power cables 42 or a specially dedicated cable. Thus, one of the light modules 10, 10 ', 10' 'synchronizes all of the light modules so as to produce the light beam of the light device 1.
    FIG. 7 illustrates a light module 110 according to a second embodiment. This comprises a support 120 formed by a plate with lateral tabs 134, as for the light module 10 of the previous embodiment.
    In the same way, the support 120 comprises a horizontal part 121 connected to a vertical part 122, each part comprising curved edges forming fins 137.
    Each of these two parts also forms limitations for a housing space 128, inside which are housed the LED 111 and its control device 112.
    However, this light module 1110 differs from the light module 10 of the previous embodiment in that the LED 111 is mounted on the lower face 123 of said horizontal part 121, while the control device 112 is mounted on the front face 124 of said vertical part 122.
    The printed circuit 115 is also mounted on the lower face 123 of the horizontal part 121, the LED 111 being connected to the electrical tracks of the printed circuit 115, also by metal blades.
    The control device 112 is connected to the printed circuit 115 via a connection cable 127 comprising several connection wires. In this example, it is a ribbon cable 127 pressed along the plate forming the support 120, namely that from the control device 112, the ribbon cable 127 is pressed against the front face 124 of said vertical part. 122, then marries the curved portion 129 which connects the latter to the horizontal plate 121, then is pressed against the lower face 123 of this horizontal plate 121, to then connect to the printed circuit 115, for example by means of a soldered connector to the printed circuit 115.
    This embodiment can be used in particular in cases where the heat given off by the control device 112 is much stronger than that given off by that of the first embodiment, and would risk disturbing the correct functioning of the LED 111. Indeed , the piloting device 112 is here away from the LED 111, being arranged on a portion of the plate 120 distinct from the portion carrying the LED 111.
    For the rest, this light module 110 can be mounted in the same way in the light device by means of the lateral tabs 134 in corresponding runners, until their front edges 136 abut against the bottoms of the runners.
    In this case, this light module 110 could be mounted on the light device 1 illustrated in Figures 3 and 4, in place of the light modules 10, 10 ', 10' '.
