Description

DESCRIPTION TITLE: LIGHTING SYSTEM INCLUDING A LOGO TECHNICAL FIELD OF THE INVENTION

[0001] The technical field of the invention is that of lighting systems for motor vehicles (private vehicles or utility vehicles). The invention also relates to a lighting assembly capable of emitting a lighting and / or signaling function and including such a lighting system.

[0002] The present invention relates in particular to light assemblies intended to be located at the front or rear of a vehicle. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0003] It is known to have on a motor vehicle, in particular on a front face, on a rear face, on a side face or in a vehicle interior, logos or distinctive signs of brands, ranges or models of motor vehicles. These elements are subsequently referred to as "logos" throughout this document. Such logos may lack appeal and be little noticed by users of a vehicle and by third parties likely to encounter the vehicle.

[0004] Various design research and conception efforts are aimed at making these logos: - more attractive to vehicle users and to third parties who may observe the vehicle, and - more noticeable by users of the vehicle and by third parties likely to observe the vehicle.

[0005] One solution to make these logos more attractive or more remarkable is to illuminate them, especially backlighting them.

[0006] However, such a solution complicates the logo and makes it less robust. SUMMARY OF THE INVENTION

[0007] The invention offers a solution to the problem mentioned above, by making illuminated and / or backlit logos more reliable.

[0008] According to the invention, a lighting system intended to be mounted on a motor vehicle comprises: an assembly of at least one light source constituting or illuminating a logo, and at least a first electrical power supply module for the assembly of at least one light source and at least a second electrical power supply module for the assembly of at least one light source.

[0009] One or more light sources of the set of at least one light source may be redundantly powered by the first power supply module and the second power supply module.

[0010] The set of at least one light source may comprise several light sources forming at least a first group of light sources and a second group of light sources forming at least a second group of light sources, the first power supply module powering the first group of light sources, and the second power supply module powering the second group of sources.

[0011] The light sources of the first group can be distributed as homogeneously as possible over the entire visible surface of the logo and / or in a manner adapted to the geometry of the logo, and / or the light sources of the second group can be distributed as homogeneously as possible over the entire visible surface of the logo and / or in a manner adapted to the geometry of the logo.

[0012] The first power supply module may be intended to be mounted on a right side of a vehicle and the second power supply module may be intended to be mounted on a left side of a vehicle.

[0013] According to the invention, a light assembly intended to be mounted on a motor vehicle comprises: a main housing comprising a first side with a front opening and a second side, opposite the first side, with a rear opening arranged opposite at least part of the front opening, a lighting device with a secondary housing, a glass sealing the front opening of the first side of the main housing, and a lighting system defined previously.

[0014] The light device may be housed in the rear opening of the second side of the primary housing and the secondary housing may be tightly and reversibly attached to the second side of the primary housing.

[0015] The first power supply module may be arranged in a right secondary housing and the second power supply module may be arranged in a left secondary housing.

[0016] The ice can be irreversibly attached to the main housing.

[0017] The secondary housing can be opened on one front side and the glass can close the front side of the secondary housing.

[0018] The lighting device may comprise a light source and an optical deflecting element and / or the lighting device may be a projector or a rear light.

[0019] The light assembly may include at least one light guide placed in the main housing behind the glass.

[0020] The light guide can be powered by a light source located in the headlight or in the taillight. BRIEF DESCRIPTION OF THE FIGURES

[0021] The figures are presented as indicative and in no way limiting examples of the invention.

[0022] Figure 1 is an exploded view of one embodiment of a light assembly.

[0023] Figure 2 is a partial view of the embodiment of such an assembly.

[0024] Figure 3 is another partial view of the embodiment of such an assembly.

[0025] Figure 4 is a schematic view of a first embodiment of a lighting system.

[0026] Figure 5 is a schematic view of a second embodiment of the lighting system. DETAILED DESCRIPTION

[0027] Unless otherwise specified, the same element appearing in different figures has a single reference.

[0028] Throughout the description we will call "front" the side from which the light comes out and "back" the opposite side or from which the light is emitted.

[0029] In the first embodiment illustrated in Figure 1, the light assembly 1 comprises two light devices formed by two projectors 2, a main housing 3 and a window 4. The description is made here for light devices formed by front projectors but this would apply in the same way for light devices formed by rear lights. The main housing 3 comprises a first side with a front opening 32, and a second side, opposite the first side, with two rear openings 30. In an alternative not shown, the light assembly may comprise only a single projector, and the main housing may comprise only a single rear opening.

[0030] In the illustrated example, the main housing 3 has an elongated shape having two ends 39a, 39b. The front opening 32 extends from one end 39a to the other 39b of the main housing 3, that is to say over the entire surface of the main housing 3. The rear openings 30 are each arranged opposite the front opening 32, at one of the ends of the main housing 3.

[0031] The glass 4 is arranged opposite the front opening 32 of the main housing 3. It closes the front opening of the main housing 3 in a sealed manner. In the example illustrated, the glass 4 is fixed to the main housing 3 by gluing. To do this, the glass 4 may comprise a rib, and the main housing 3 may comprise a slot receiving the rib. To secure the glass 4 to the main housing 3 by gluing, glue is introduced into the slot, and the rib of the glass 4 is then introduced into the slot. Alternatively, the glass 4 could be assembled to the main housing 3 by welding, or by a hotplate process. It is thus understood that the glass 4 is fixed not only in a sealed manner to the main housing 3, but also irreversibly, or in other words in a non-removable manner. The glass 4 and the main housing 3 thus form a non-removable strip 10. By non-removable, it is meant that it is not possible to detach the glass 4 from the main housing 3 without damaging the glass 4 and / or the main housing 3.

[0032] The projectors 2 are each arranged at one end of the main housing 3, opposite one of the rear openings 30 of the main housing 3, and they are attached to the main housing 3. The projectors 2 each have a front opening adapted to the rear opening 30 of the main housing 3.

[0033] When the light assembly 1 is mounted on a vehicle, the strip 10 covers the entire width of the front of the vehicle, and the two projectors 2, arranged at each end of the main housing 3, thus constitute a right projector and a left projector of the vehicle. Alternatively, when the light assembly 1 is mounted on a vehicle, the strip 10 can cover the entire width of the rear of the vehicle.

[0034] The projectors 2 comprise, for example, at least one light source and an optical deflection element, such as, for example, a reflector, a lens or a light guide, making it possible to shape the light rays emitted by the light source to form at least part of a lighting or signaling beam. For example, the projectors 2 may comprise light modules comprising the at least one light source and the optical deflection element.

[0035] The glass 4 also being arranged opposite the rear openings 30 of the main housing 3, the lighting or signaling beam formed by each projector 2 can thus pass through the glass 4, and be visible from outside the lighting assembly 1.

[0036] Each projector 2 comprises a secondary housing 21 attached for example to the main housing 3 in a sealed and reversible manner.

[0037] The secondary housing 21 comprises attachment elements which cooperate with complementary attachment elements arranged on the main housing 3. For example, the attachment elements of the secondary housing 21 may be formed by ears arranged at the periphery of the secondary housing 21 and comprising a through hole, and the complementary attachment elements arranged on the main housing 3 can be formed by screw barrels. Thus, fixing screws can be inserted into the through holes and into the screw barrels in order to attach the secondary housing 21 and the main housing 3 together in a reversible manner. The projectors 2 can thus be removable from the main housing 3 and therefore from the strip 10.

[0038] The light assembly 1 advantageously comprises a seal positioned in a groove of the secondary housing 21, and placed in abutment on the main housing 3 in order to guarantee a sealed fixing between the projector 2 and the strip 10. When the secondary housing 21 is assembled to the main housing 3, the fixing screws are tightened, which brings the main housing 3 and the secondary housing 21 into contact, thus compressing the seal between the main housing 3 and the secondary housing 2. The seal between the main housing 3 and the secondary housing 2 is thus guaranteed.

[0039] In this example, the headlights 2 do not have their own closing glass. In other words, a front opening 25 of each headlight is not closed by a glass specific to the headlight. It is the glass 4 which makes it possible to indirectly and tightly close the front opening 25 of each headlight 2, and thus to protect the headlights 2. Indeed, the glass 4 closes the front opening 32 of the main housing 3 tightly, and the secondary housing 21 of each headlight 2 is fixed tightly to the main housing 3 at the rear openings 30. Thus, the glass 4 ensures the tight closing of the front openings 25 of the headlights 2.

[0040] In a variant not shown, the front opening 25 of the projectors 2 can be sealed by a glass specific to the projector 2.

[0041] In the non-limiting example illustrated, the light assembly 1 also comprises a plurality of light guides 5, a support 50 for the light guides 5 and a mask 6. The support 50 for the light guides 5, the light guides 5 and the mask 6 are arranged between the main housing 3 and the glass 4, and more precisely between the first side of the main housing 3 and the glass 4. The support 50 for the light guides 5, the light guides 5 and the mask 6 are thus sandwiched between the housing main 3 and the ice 4. The strip 10 thus includes the light guides 5, the support 50 of the light guides 5 and the mask 6.

[0042] The support 50 of the light guides, the light guides 5 and the mask 6 are optional. The strip 10 may comprise only the main housing 3 and the glass 4. It is also possible that the strip 10 comprises only the main housing 3, the glass 4 and one or other of the mask 6 or the assembly formed by the support 50 of the light guides 5 and the light guides 5.

[0043] The light guides 5 make it possible to form a light signature specific to the vehicle on which the light assembly 1 is mounted. In the example illustrated, the light assembly comprises six light guides 5 distributed along the periphery of the front face of the main housing 3. Two curved lateral light guides 5a are located at each end of the main housing 3, and two central light guides 5b joining the lateral light guides 5a in pairs. This distribution of the light guides 5 makes it possible to optimize the guidance of the light in the curved parts. However, the number of light guides is not limiting, and a single light guide, or two light guides could for example be used.

[0044] The light guides 5 can be placed in a groove of the support 50 of the light guides 5, in order to be held in position.

[0045] Each light guide 5 is powered by at least one light source arranged in one of the projectors 2. The light sources powering the light guides 5 are positioned in the secondary housing 21 of the projectors 2 and powered by a dedicated power supply module 120a, 120b, such as a dedicated printed circuit board. Thus, the strip 10 may not include any electronic components or may include few electronic components, which makes it easier to replace the strip or one or other of the projectors 2 independently. It will be noted that the light sources powering the light guides 5 are advantageously distinct from the light sources forming the lighting or signaling beams of the projectors 2.

[0046] The central light guides 5b are each powered by a light source arranged in one of the projectors 2 at their first end, and a light source arranged in the other of the projectors 2 at their second end. In Figure 1, we can see the two light inputs 15b of the central light guides 5b. This double power supply of the central light guides 5b makes it possible to illuminate the central light guides 5b in a homogeneous manner. The lateral light guides 5a are powered by a single light source arranged in the projector 2 located at the same end of the main housing 3 as the corresponding lateral light guide 5a. In Figure 1, the light inlet 15a of the lateral light guides 5a can be seen.

[0047] In an embodiment not shown, it may be envisaged to power the lateral and / or central light guides by light sources arranged, in combination with its dedicated printed circuit board, between the projector 2 and the area of ​​the main housing 3 where the light inputs of the corresponding light guides are located.

[0048] In another embodiment not shown, it may be envisaged to power the lateral and / or central light guides by light sources arranged, in combination with its dedicated printed circuit board, in the main housing 3 in the area where the light inputs of the corresponding light guides are located.

[0049] The mask 6 is arranged at the front of the support 50 of the light guides 5 and the light guides 5. The mask 6 comprises two orifices 60 placed at its ends, and arranged opposite the rear openings 30 of the main housing 3. The orifices 60 are therefore also located opposite the projectors 2, and in particular opposite the front openings 25 of the projectors 2. The lighting or signaling beams emitted by the projectors 2 can thus be transmitted through the rear openings 30, the front opening 32 and the orifices 60 to the glass 4, so that they are visible from outside the light assembly 1.

[0050] The mask 6 comprises an opaque part 63 making it possible to mask certain parts of the light assembly 1, and in particular the central part of the light assembly 1, as well as a transparent part 61 arranged opposite the light guides 5, in front of the light guides 5. The light guides 5, and the light emitted by the light guides 5 can thus be visible from outside the light assembly 1.

[0051] In addition, on the front face of the mask 6, corresponding to the face facing the window 4, it is possible to draw patterns in order to give the vehicle a style. For example, the patterns can be geometric shapes.

[0052] The support 50 of the light guide 5 and the mask 6 are assembled together for example by clipping or screwing, and the light guides 5 are positioned and held by being sandwiched between the support 50 and the mask 6. Alternatively, the support 50 and the mask 6 could be assembled by gluing. The assembly by clipping or screwing makes it possible to limit the assembly time compared to an assembly by gluing which requires a drying time.

[0053] Once assembled, the support 50, the light guides 5 and the mask 6 are positioned between the main housing 3 and the glass 4, being sandwiched between the main housing 3 and the glass 4. Thus, the strip 10 comprising the main housing 3, the support 50, the light guides 5, the mask 6 and the glass 4 is assembled in a non-removable manner.

[0054] The headband further comprises a logo 7 arranged between the housing 3 and the crystal 4. Preferably, the logo 7 is fixed to the housing 3. The logo may appear at an opening 69 provided in the mask 6. For example, the housing 3 may comprise an opening 39, in particular a central opening 39 and the logo 7 may be fixed to the mask at this opening 39 so as to close it and to seal the headband 10. Such an opening makes it possible in particular to mount the logo 7 from the rear, that is to say after the crystal has been fixed to the housing 3. To do this, the logo 7 is introduced through the opening 39 from the outside of the headband towards the inside, then the logo 7 is fixed to the main housing 3.

[0055] The light assembly 1 is advantageous in that in the event of an impact on the glass 4 or in the event of a malfunction of one of the projectors 2, it is possible to change only the strip 10 and keep the projectors 2, or to change only one of the projectors 2 and keep the strip 10 and the other projector 2. In the case where the logo 7 is fixed after passing through the opening 39, it is also possible to keep the logo which can be removed.

[0056] To change the strip 10, simply remove the light assembly 1, then unscrew the two projectors 2 from the strip 10, and screw the two projectors 2 back onto a new strip. To change one of the projectors, simply remove the light assembly 1, then unscrew the projector 2 to be changed and replace this defective projector 2 with another projector.

[0057] In this embodiment, the strip 10 can be more or less complex depending on the options (with or without light guide, etc.), and thanks to the removable assembly of the projectors 2 on the strip 10, it is possible to mount different projectors 2, more or less sophisticated, on the strip 10, depending on the desired performance for the light assembly 1.

[0058] In one embodiment, the lighting assembly 1 described above comprises a lighting assembly 100 which includes: an assembly 110 of at least one light source 111; 111a, 111b constituting the logo 7 (the logo 7 being part of the lighting assembly) or an assembly 110 of at least one light source 111; 111a, 111b illuminating the logo 7 (the logo 7 not being part of the lighting assembly), and at least one first power supply module 120a of the assembly 110 and at least one second power supply module 120b of the assembly 110 of at least one light source.

[0059] Thus, the light assembly 1 can comprise: the main housing 3 comprising a first side with the front opening 32 and the second side, opposite the first side, with the rear opening 30 arranged opposite at least a part of the front opening 32, the light device with the secondary housing 21, the glass 4 closing the front opening of the first side of the main housing 3 in a sealed manner, and the light system 100 which is described in more detail below.

[0060] Alternatively, a lighting system 100 including: an assembly 110 of at least one light source 111; 111a, 111b constituting or illuminating a logo 7, and at least one first electrical power supply module 120a of the assembly 110 of at least one light source and at least one second electrical power supply module 120b of the assembly 110 of at least one light source, can be provided independently of the lighting assembly 1 described above.

[0061] Advantageously, the logo 7 is a luminous logo, in particular intended to produce a remarkable or attractive visual effect on a third party having this logo in their field of vision. To do this, the logo 7 is either an illuminated part, in particular backlit, or constituted by one or more light sources 1 1 1; 1 1 1 a, 1 1 1 b whose geometries and / or distributions are adapted to form a sign visible to a third party.

[0062] In the case where the logo 7 is a room illuminated by the light source(s) 1 1 1 ; 11 1 a, 1 1 1 b, the room may be a room which is configured and / or arranged to reflect towards the third party at least a portion of the light rays emitted by the light source(s) 1 1 1 ; 1 11 a, 11 1 b. The room may therefore be opaque. Alternatively, the room may be a room which is configured and / or arranged to transmit towards the third party at least a portion of the light rays emitted by the light source(s) 1 1 1 ; 1 1 1 a, 1 11 b. The room is then advantageously transparent or translucent. Alternatively again, the room may be transparent or translucent and be configured and / or arranged with the light sources so that the room: - transmits to a third party at least part of the light rays emitted by certain light sources, and - reflects at least one third of the light rays emitted by other light sources. Alternatively, the part may comprise one or more translucent or transparent parts and one or more opaque parts.

[0063] Advantageously, the part constitutes a physical or mechanical support allowing the fixing or holding in position of the light sources 11 1 ; 1 1 1 a, 1 1 1 b. Furthermore, the part can constitute a physical or mechanical support allowing the fixing or holding in position of the conductors and connector 140 allowing the electrical supply of the light sources from the first electrical supply module 120a and the second electrical supply module 120b, via bundles 130a, 130b of electrical conductors. The connector 140 makes it possible to electrically connect the bundles 130a, 130b to the logo 7 or to the light sources illuminating the logo 7.

[0064] As shown in Figures 2 and 3, the second power supply module 120b can be attached to the left headlight 2. From the second power supply module 120b, the power signal travels: - in a 162b beam, then - in a bundle 164b connected to the bundle 162b via connectors 163b and comprising light sources arranged opposite the inputs 15a, then - in a beam 166b connected to the beam 164b via connectors 165b and comprising light sources arranged opposite the inputs 15b, then - in the harness 130b connected to the harness 166b via connectors 167b and 150b, then the signal feeds the light sources 1 1 1 or 1 1 1 b.

[0065] Preferably, the right part of the lighting system 100 or of the lighting assembly 1 has a structure similar (or identical, in particular symmetrical) to that described in the previous paragraph. It is therefore not described further.

[0066] The light sources are preferably light-emitting diodes. In particular, the light sources can be of the OLED type. The following technologies could also be used: - light guides, in particular round light guides, - illuminating blades (rectangular and elongated section), - reflectors in combination with light-emitting diodes, in particular to reduce the number of light-emitting diodes.

[0067] The first power supply module 120a of the assembly 110 of at least one light source may comprise a first printed circuit board. It is preferably located at a right end of the light assembly, in particular in a right secondary housing 21.

[0068] The second power supply module 120b of the assembly 110 of at least one light source may comprise a second printed circuit board. It is preferably located at a right end of the light assembly, in particular in a left secondary housing 21.

[0069] The first power supply module 120a and the second power supply module 120b are separate and independent. Accordingly, a malfunction or failure of one of the first and second power supply modules normally has no effect on the operation of the other of the first and second power supply modules.

[0070] Two embodiments of a lighting system are described below with reference to figures 4 and 5. These modes differ by the nature of the electrical connections of the light sources and therefore by the nature of the electrical power supplies of the light sources 1 1 1; 1 1 1 a, 1 1 1 b.

[0071] In the embodiment described with reference to FIG. 4, the light sources 11 1 are all connected in parallel and powered simultaneously by both the first power supply module 120a and the second power supply module 120b. Preferably, the connector 140 may comprise diodes 121a and 121b to prevent a power supply signal from one of the first and second power supply modules from attacking the other power supply module. As a result of this structure, even in the event of a failure of one of the power supply modules 120a and 120b, all the light sources can remain powered by the other power supply. In such a case, the light sources all emit radiation which is, however, a little weaker than when both power supply modules 120a and 120b are in operation.The light sources 11 1 of the set 110 of at least one light source are thus supplied redundantly by the first power supply module and by the second power supply module.

[0072] Advantageously, in the embodiment described with reference to FIG. 4, the light sources 111 are distributed as uniformly as possible over the entire surface of the logo 7, in particular over the entire visible surface of the logo for one third. This makes it possible to ensure the most uniform lighting of the logo possible over its entire visible surface for one third, regardless of the operating state of the power supply modules 120a, 120b.

[0073] In the embodiment described with reference to FIG. 5, the light sources 11 1 a, 1 1 1 b form a first group of light sources 1 1 1 a and a second group of light sources 1 1 1 b. In each group, all the light sources are connected in parallel and powered by a single module. power supply module 120a, 120b. The first group of light sources 1 1 1 a is powered by the power supply module 120a, in particular via the harness 130a and the connector 140. The second group of light sources 1 1 1 b is powered by the power supply module 120b, in particular via the harness 130b and the connector 140. As a result of this structure, even in the event of a failure of one of the power supply modules 120a and 120b, certain light sources can remain powered by the other power supply. In such a case, certain light sources are switched off and other light sources emit nominal radiation. Overall, such an architecture ensures redundancy of the power supply for the lighting of the logo 7.

[0074] Advantageously, in the embodiment described with reference to FIG. 5, the light sources 1 1 1 a of the first group are distributed as homogeneously as possible over the entire surface of the logo 7, in particular over the entire visible surface of the logo for one third, and / or the light sources 1 1 1 b of the second group are distributed as homogeneously as possible over the entire surface of the logo 7, in particular over the entire visible surface of the logo for one third. This ensures that the logo is illuminated as uniformly as possible over its entire visible surface for a third party, regardless of the operating state of the power supply modules 120a, 120b. Preferably, in each group of light sources, the light sources are distributed so as to obtain uniform backlighting of the logo 7 in the event of failure of the light sources in the other group.

[0075] In another embodiment not shown, the embodiments of Figures 4 and 5 can be combined. Thus, some light sources of the set of light sources can be supplied redundantly by the first power supply module and by the second power supply module, other light sources of the set of light sources can be supplied exclusively by the first power supply module and still other light sources of the set of light sources can be supplied exclusively by the second power supply module.

[0076] In variations, regardless of the embodiment, more than two power supply modules may be used to power the lighting of the logo 7.

[0077] Regardless of the embodiment, the first power supply module 120a may be intended to be mounted on the right side of a vehicle and the second power supply module 120b may be intended to be mounted on a left side of a vehicle.

[0078] Advantageously, if the lighting system 100 is implemented in the lighting assembly 1 described above, the first electrical power supply module 120a can be arranged in a right secondary housing 21 and the second electrical power supply module 120b can be arranged in a left secondary housing 21.

[0079] Whatever the embodiment, in the case where the logo 7 is mounted from the rear, an excess length of the harnesses 130a and 130b is provided, making it possible to connect, via the connector 140, the harnesses 130a and 130b to the logo 7 while the latter is not yet fixed to the housing 3, then to mechanically fix the logo 7 to the housing 3. As seen previously, this fixing advantageously makes it possible to close the opening 39.
