Description

Title of the invention: Lighting system for vehicles comprising at least two juxtaposed lighting devices. Technical field

[0001] The present invention relates to a vehicle lighting system comprising at least two lighting devices. Technological background

[0002] The lighting systems of motor vehicles now fulfill several functions, such as illuminating and defining a vehicle's light signature. Lighting allows the driver of a vehicle to accurately perceive its surroundings and to be seen by other road users. The light signature, for its part, makes it easy to identify a vehicle, both day and night.

[0003] Such lighting devices are integrated, for example, into the exterior silhouette of a vehicle or its passenger compartment. These lighting devices generally comprise numerous components including light sources, electronic boards, electrical harnesses, optical elements capable of guiding light rays, decorative elements, cooling means, and adjustment means.

[0004] The various lighting and signaling functions are achieved in particular from a plurality of lighting devices, physically separate or juxtaposed, for example in an optical unit. Each lighting device generally comprises a housing, one or more electrical connectors, a support mounted on the housing and a lighting system mounted on the support.

[0005] These lighting devices must meet several requirements, including robustness, compactness, lightness, aesthetics, and cost-effectiveness. In particular, they must be mechanically resistant and must not vibrate when the vehicle on which they are mounted is in motion. Indeed, if a lighting device or some of its components vibrates, then the light beam emitted by that device is unstable and generates visual discomfort, for example, for the driver of the vehicle if the lighting device illuminates a road on which they are traveling. Conversely, it is necessary to reduce the amount of material in the components of the lighting device in order to make it lighter for economic and environmental reasons (cost, less material consumed, increased vehicle range, etc.) and to make it more compact to facilitate its integration into a vehicle.Thus, the components are, for example, thinned, which reduces their rigidity and strength. mechanical. The design of a lighting system comprising lighting devices that meet several of these requirements is therefore complex. Summary of the present invention

[0006] The present invention overcomes the technological background problems described above by designing a lighting system that meets several of the requirements at once, in particular a lighting system that is mechanically strong, lightweight and compact, the mechanical strength making it possible to considerably reduce vibrations, or even eliminate vibrations.

[0007] To this end, the invention relates firstly to a lighting system for a vehicle, the lighting system comprising a first and a second juxtaposed lighting devices, the first lighting device comprising a first reflector and the second lighting device comprising: - a second reflector, - an electronic board associated with at least one light emitter, the light emitter being capable of cooperating with the second reflector, and - a support including a plate configured to receive the electronic board.

[0008] According to the lighting system of the invention, the support is compressed between the first reflector and the second reflector, assembly means being configured to assemble the support, the first reflector and the second reflector.

[0009] Such a lighting system makes it possible to take advantage of the rigidity of the support by transferring it to both the first and second reflectors. Thus, the rigidity, and therefore the mechanical strength, of each of the lighting devices is increased by combining the rigidities of the reflectors and the support. Each of the juxtaposed lighting devices is therefore more rigid without increasing the number of components or adding any parts, thereby avoiding an increase in the size and / or mass of each individual lighting device, and thus preserving the compactness and lightness of the lighting system.

[0010] According to an advantageous embodiment, the support includes first openings allowing the passage through the support of first fastening elements from the first reflector to the second reflector, the support stiffening each of the first and second reflectors. Such first fastening elements, for example screws, are commonly used to achieve this type of assembly.

[0011] According to an advantageous embodiment, the support includes second openings configured to allow the passage of guide elements belonging to the first reflector and / or guide elements belonging to the second reflector. Thus, during the assembly phase of the lighting system, the reflectors are easily positioned relative to the support thanks to the guide elements.

[0012] According to an advantageous embodiment, the guiding elements of the first reflector are configured to fit into housings made in the second reflector. The first support is thus correctly positioned relative to the first reflector, and the second reflector is in turn correctly positioned relative to the first reflector. The same guide element from the first reflector is then used to position both the support and the second reflector.

[0013] According to an advantageous embodiment, the support comprises fins configured to increase the contact area with the ambient environment. Such fins cool the support, which is itself in contact with the electronic board that heats up during operation; the support thus acts as a heat sink. These fins advantageously increase the rigidity of the support.

[0014] According to an advantageous embodiment, the support includes third openings allowing the passage through the support of second elements for attaching the support to the first and / or second reflector. The support is thus first attached to one of the reflectors before assembling the other reflector, allowing each component to be mounted one after the other.

[0015] According to an advantageous embodiment, the support includes at least one boss configured to receive at least one light emitter. This boss allows the light emitter to be precisely positioned so that it is correctly positioned relative to the second reflector with which it cooperates, the second reflector itself being positioned relative to the support.

[0016] According to an advantageous embodiment, the support is made in one piece from a metallic material, preferably by stamping and bending. This manufacturing process is economical and suitable for large-scale production.

[0017] According to an advantageous embodiment, the second reflector comprises a set of screw holes, each screw hole in the set being surrounded by ribs, the screw hole being configured to receive a first fastener or a second threaded fastener, the upper surfaces of the ribs defining a bearing surface configured to receive the support plate. The screw holes thus allow the bearing areas of the support to be located and provide a robust technical solution for screwing in fasteners.

[0018] According to an advantageous embodiment, the lighting system according to the invention comprises another support configured to receive another electronic board associated with at least one other light emitter, the other light emitter being capable of cooperating with the first reflector. Thus, each lighting device represents a similar construction module.

[0019] According to an advantageous embodiment, the other support includes fourth openings allowing the passage of third fastening elements configured to fix the other support to the first reflector. The other support is thus fixed to the first reflector by a commonly used means of assembly, for example fixing screws.

[0020] According to an advantageous embodiment, the first and second lighting devices are superimposed. Such a construction allows these lighting devices to be vertically integrated into the vehicle.

[0021] According to an advantageous embodiment, the first and second lighting devices are arranged side by side. Such a construction allows these lighting devices to be integrated horizontally into the vehicle.

[0022] The invention also relates to a vehicle comprising the lighting system as described above.

[0023] Thus, thanks to all the functional and structural technical features of the present invention, a lighting system is available that is mechanically robust, lightweight, and compact. These characteristics make it easy to integrate this lighting system into various vehicles. Brief description of the figures

[0024] The features and advantages of the present invention will become apparent from the description below, with reference to the attached Figures 1 to 9, which illustrate various embodiments without being limiting in any way and on which: - Fig. 1 represents a perspective view of a lighting system according to the present invention from a first point of view, according to a particular embodiment; - [Fig.2] represents a perspective view of a support for the lighting system of [Fig.1], from a second point of view; - [Fig.3] represents a perspective view of a support for the lighting system of [Fig.1], from a third point of view; - [Fig.4] represents a perspective view of a support, an electronic board and a light emitter of the lighting system of [Fig.1], from the third point of view; - [Fig.5] represents a perspective view of a second reflector of the light system of [Fig.1], from the first point of view; - [Fig.6] represents a perspective view of a second reflector and a support for the lighting system of [Fig.1], from a fourth point of view; - [Fig. 7] represents a perspective view of a first reflector and a support for the lighting system of [Fig. 1], from a fifth viewpoint; and - [Fig.8] represents an exploded view of the lighting system of [Fig.1], from the first viewpoint; - [Fig.9] represents an exploded view of the lighting system of [Fig.1], from a sixth point of view. Description of examples of achievements

[0025] An example of a lighting system will now be described with reference to Figures 1 to 9. According to this example, the lighting system 1 comprises a first and a second juxtaposed lighting devices, the first lighting device comprising a first reflector and the second lighting device comprising: - a second reflector, - an electronic board associated with at least one light emitter capable of cooperating with the second reflector, and - a support comprising a plate configured to receive the electronic board. Indeed, the lighting system is characterized in that the support is compressed between the first reflector and the second reflector, assembly means being configured to assemble the support, the first reflector and the second reflector.

[0026] Figure 1 shows a perspective view of a lighting system according to the present invention from a first point of view, according to a particular embodiment. The lighting system 1 is, for example, part of a front optical unit of a vehicle comprising a first lighting device D1 intended to perform the function of the low beam, also called the "dipped beam," and a second lighting device D2 intended to perform the function of the high beam. It should be noted that the lighting device corresponding to the high beam is located below the lighting device corresponding to the low beam. This is explained by the fact that an optical lens is, for example, placed in front of the devices; the light beams they emit then have their position reversed by an optical effect of the lens placed in the path of these light beams. Thus, this particular embodiment shows the first and second lighting devices superimposed.

[0027] According to another particular embodiment, not shown in the figures, these first and second lighting devices may be arranged side by side, for example when the optical unit has a more horizontal shape, or when the first lighting device DI is associated with a high or low beam and the second lighting device D2 is associated with a position light or a turn signal. Those skilled in the art will therefore understand that the following description, which applies to two superimposed lighting devices, can be applied mutatis mutandis to lighting devices arranged side by side, by making simple adjustments to the parts.

[0028] As illustrated in [Fig. 1], each of these lighting devices comprises components such as a reflector, a support, an electronic board, and a light emitter. It should be noted, however, that an electronic board or printed circuit board (“ PCB") is used for a light emitter comprising at least one light-emitting diode ("LED"). The first lighting device DI may, according to one variant, not include an electronic board because it alternatively includes a bulb, for example halogen, which does not require such a component.

[0029] Regardless of the lighting technology used, the first lighting device DI comprises a first reflector 11 and the second lighting device D2 comprises a second reflector 12. These reflectors are, for example, made of a thermoplastic material coated with a layer of a reflective material, obtained, for example, by surface treatment. Such reflectors have the advantage of being lightweight. The thermoplastic material is, for example, polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or polyamide (PA); the coating contains, for example, aluminum, silver, and / or chromium. The role of the reflector is to reflect one or more light beams emitted by a light emitter and to direct them in a specific direction, for example, towards the front of the vehicle, via, for example, an optical system comprising at least one lens (not shown) and through a diffuser (not shown).These reflectors are designed to illuminate specific areas such as the road and shoulders, or conversely, to avoid illuminating certain areas in order, for example, to prevent dazzling other road users. Therefore, the shape of the reflectors' reflective surfaces is functional and cannot incorporate certain technical features that would allow, for example, the attachment of another component by screwing. Indeed, to allow this screwing, it is necessary to create a screw hole, but this type of protrusion risks creating a sink mark on a functional surface of the reflector, thus degrading the reflector's primary function: reflecting light beams. Similarly, adding ribs to stiffen a reflector is prohibited, as thick ribs also generate sink marks.Thus, improving the mechanical properties of these reflectors requires, for example, thickening them or changing their material, thereby increasing their mass and size or forcing the manufacturer to redesign their production equipment to accommodate new materials. The present invention proposes an alternative solution for increasing the mechanical strength of the first and second reflectors 11, 12 without changing their material or thickness and without creating surface defects such as sink marks.

[0030] The optical system 1 also includes an electronic card 13 and a support 10, the support 10 being compressed between the first reflector 11 and the second reflector 12.

[0031] Figure 2 shows a perspective view of the support 10 of the lighting system 1 of [Fig.1] from a second point of view.

[0032] The support 10 includes first openings 101 allowing the passage through the support 10 of first fastening elements 98 (illustrated [Fig. 8]) from the first reflector 11 to the second reflector 12. Such first fastening elements 98 are, for example, screws, the threaded portion of which fits into the second reflector 12 so as to clamp the first reflector 11 under its head. The support 10, positioned in this way, is then compressed between the first reflector 11 and the second reflector 12. When the fastening elements 98 are in effect, that is, when the screws are tightened, the first reflector 11, the support 10, and the second reflector 12 become a single unit, the support 10 then stiffening each of the first and second reflectors 11 and 12. Indeed, no movement is possible between these three components once the first fastening elements are in place. 98 employees.Thus, when a force is applied to one of these three components, they bond together and the generated stresses are distributed across the different components. Therefore, through the assembly of the components, the mechanical properties of each are improved and their ability to withstand stress is increased.

[0033] The support 10 also includes third openings 103 allowing the passage through the support 10 of second fixing elements 99 (illustrated [Fig.8]) of the support 10 to the first reflector 11 and / or to the second reflector 12. In the example illustrated here, the second fixing elements 99 allow the assembly of the support 10 to the second reflector 12. These second fixing elements 99 allow the support 10 to be assembled first on the second reflector 12, before this sub-assembly comprising the support 10 and the second reflector 12 is assembled secondly to the first reflector 11.

[0034] Fig. 3 represents a perspective view of the support 10 of the light system 1 of Fig. 1 from a third point of view.

[0035] The support 10 includes a plate 104 configured to receive the electronic card 13 as illustrated in [Fig. 4], the plate 104 having large flat surfaces so as to conform to the shape of the electronic card 13 (illustrated in [Fig. 4]) which the support 10 receives. On this plate 104 are pins 107, in this example two in number, allowing the electronic card 13 to be positioned and, for example, crimped by deforming the end of each pin 107. By means of this assembly, the electronic card 13 is not subjected to stresses such as those generated by the force exerted by a screw under its head when it is tightened. This electronic board 13 is associated with at least one light emitter 14 (illustrated [Fig.4]), the light emitter 14 being able to cooperate with the second reflector 12. In this example, the number of light emitters 14 is two, but is generally at least one.Indeed, the second reflector 12 here presents two distinct reflective areas, however their number is not limited to two and is . for example 1, 3, 4 or more depending on the size of the reflector and the expected visual effect. Indeed, in the case of a matrix-type lighting system, that is to say comprising several independently controlled light beams in order to adapt to the vehicle's environment, the number of light emitters 14 is then significantly higher.

[0036] According to this particular embodiment, the support 10 includes at least one boss 106 configured to receive at least one light emitter 14. These bosses 106 allow the light emitters 14 to be precisely positioned on the support 10, which is positioned relative to the second reflector 12. If a light emitter 14 is positioned directly on the electronic board 13, then the electrical connection to the electronic board 13 is facilitated. However, if the electronic board 13 is itself placed on the support 10 positioned relative to the second reflector 12, the number of elements in the dimension chain used to determine the relative position of the light emitter 14 with respect to the second reflector 12 is greater, and therefore the inaccuracy in positioning the light emitter 14 with respect to the second reflector 12 is higher.Thus, this embodiment in which the light emitter 14 is positioned on the support 10 improves the positioning accuracy of the emitter 14 relative to the second reflector 12 by adding a link in this chain of ribs. The emitter 12 is then connected to the electronic board 13 by a flexible link, here two flexible electrical wires.

[0037] During operation, the electronic board 13 and at least one light emitter 14 heat up, i.e., they emit heat which is then dissipated into the ambient air. If the support 10 is a good heat sink, i.e., if it is made of a material with a high thermal capacity, also called heat capacity, for example a metal, it is then able to dissipate some of the heat emitted by the electronic board 13 and at least one light emitter 14. In this particular embodiment, the support 10 includes fins 105 (illustrated [Fig. 2]) configured to increase the contact area with the ambient environment. These fins 105 then allow it to exchange more efficiently the calories that it absorbs from the electronic board 13 and at least one light emitter 14 and that it transports with the ambient air.These fins 105 are obtained, for example, by bending external or internal parts that have been previously shaped. Furthermore, these fins 105 add rigidity to the support 10, which would be almost flat without them. Therefore, the support 10 is advantageously made as a single piece from a metallic material, preferably by stamping, for example from coated steel to prevent corrosion or from an aluminum alloy.

[0038] Figure 5 shows a perspective view of the second reflector 12 of the lighting system of Figure 1 from the first viewpoint. The second reflector 12 comprises a set of screw holes, each screw hole 122 being configured to receive a first threaded fastener 98 or a second threaded fastener 99. According to this particular embodiment, each screw hole 122 includes a cylindrical orifice for inserting a threaded portion of a screw, the inner diameter and depth of the cylindrical orifice being defined according to the dimensions of the screw it receives, so as to allow the threads of the screw to penetrate the material of the second reflector sufficiently to be solid but without generating excessive stress on this material that could cause the screw hole 122 to break.In other words, the screw holes 122 are self-tapping when the first fastener 98 or the second fastener 99 is screwed in. Alternatively, pre-tapping of the screw holes 122 is possible, according to an alternative embodiment. The screw holes 122 are located in areas not opposite the reflective surfaces, thus avoiding aesthetic or functional defects by limiting the potential appearance of sink marks to areas that are optically non-functional.

[0039] As illustrated in [Fig. 5], each screw hole 122 of this assembly is surrounded by ribs 124, for example three or four ribs 124 distributed regularly around the screw hole 122. A different number of ribs 124 is also conceivable, for example 2 ribs 124. The ribs 124 have a primary function of mechanically reinforcing each screw hole 122, thus enabling a stronger assembly and allowing higher screw tightening torques, thereby making the assembly process more robust. The ribs 124 have a second function of defining a support plane configured to receive the plate 104 of the support 10 in support, thereby acting as a spacer and avoiding any unwanted collision between the support 10 and the second reflector 12 and especially between the electronic board 13 and the second reflector 12.Indeed, if the electronic board 13 were to be compressed or squeezed between the reflector 12 and the support 10, it could be damaged, for example by deformation or even breakage, thus creating electrical and / or electronic problems, or the electronic components could become confined, generating a risk of local overheating of the electronic board 13. Therefore, with the ribs 124 acting as spacers, an air passage is defined, for example, between the second reflector 12 and the electronic board 13. Controlling this assembly allows for monitoring the operating conditions of the electronic board 13 and reproducing these operating conditions during tests of the electronic board 13, for example, in the laboratory. The tests performed are then representative of real-world operating conditions. From the electronic board 13, the lifespan of the electronic components can then be verified and allows for their robust dimensioning.

[0040] Fig. 6 represents a perspective view of the second reflector 12 and the support 10 of the light system 1 of Fig. 1 from a fourth point of view.

[0041] The support 10 includes second openings 102 configured to allow passage of guide elements 121 belonging to the second reflector 12. These guide elements 121 belonging to the second reflector 12 allow the support 10 to be positioned relative to the second reflector 12 during the assembly phase. It should also be noted that, according to one embodiment, the first openings 101 in the support 10 also allow for guiding screw holes 122 of the second reflector 12. Thus, as illustrated in [Fig. 6], the support 10 is positioned relative to the second reflector 12 at each of its ends via the screw holes 122 located in the first openings 101 and via the guide elements 111 (illustrated [Fig. 7]) located in the second openings 102.

[0042] Figure 7 shows a perspective view of the first reflector 11 and the support 10 of the lighting system 1 of Figure 1 from a fifth viewpoint. The support 10 includes second openings 102 configured to allow passage of guide elements 111 belonging to the first reflector 11. These guide elements 121 belonging to the first reflector 11 allow it to be positioned relative to the support 10. In this particular embodiment, the guide elements 111 are of a length that also allows them to be positioned relative to the second reflector 12. Thus, the first and second reflectors 11, 12 are positioned relative to each other by means of these guide elements 111. According to a variant, the guide elements 121 belonging to the second reflector 12 play this role, their length being increased compared to that illustrated in Figure 1.5] and the length of the guiding elements 111 belonging to the first reflector 11 being reduced compared to that illustrated in [Fig.6]. .

[0043] Figures 8 and 9 show an exploded view of the lighting system 1 of [Fig. 1] from the first and sixth viewpoints, respectively. A method for assembling the lighting system includes, for example, the following steps.

[0044] In a first step, the electronic card 13 is assembled to the support 10, the electronic card 13 being positioned relative to the support 10 using the pins 107 which are then crimped to hold the electronic card 13 on the support 10. At least one light emitter 14 is also assembled on a boss 106 of the support 10, for example by gluing.

[0045] In a second step, the support 10 is positioned on the second reflector 12 using the guide elements 121, brought against the surrounding ribs 124 screw holes 122, and fixed by screwing second fixing elements 99. The second lighting device D2 is thus assembled.

[0046] According to the embodiment illustrated in Figures 1, 8 and 9, the first lighting device DI comprises another support 15 configured to receive another electronic board 16 associated with at least one other light emitter 17, the other light emitter 17 being capable of cooperating with the first reflector 11. The other support 15 includes, in particular, fourth openings 151 allowing the passage of third fastening elements 97 configured to fix the other support 15 to the first reflector 11 and fifth openings 152 allowing the passage of other guiding elements 112 of the first reflector 11. Variations of the lighting system 1 are, however, conceivable without this support 15 and this electronic board 16. For example, the electronic board 13 may include light emitters oriented towards the first reflector 11.

[0047] In a third step, the electronic card 16 is assembled to the support 15, said electronic card 16 being positioned relative to said support 15, for example, in a similar manner to the assembly of the electronic card 13 to the support 10. At least one other light emitter 17 is also assembled on a boss of this support 15, for example, by gluing.

[0048] In a fourth step, said support 15 is positioned on the first reflector 11 using the other guide elements 112, brought against the ribs 124 surrounding screw holes, and fixed by screwing third fixing elements 97. The first lighting device DI is thus assembled.

[0049] Note that the first and second steps can be carried out before or after the third and fourth steps, the first and second lighting devices being assembled independently.

[0050] In a fifth step, the first light device DI is positioned opposite the second light device D2, the guide elements 111 of the first reflector 11 being inserted into housings 123 (illustrated [Fig.5] and 9) made in the second reflector 12 after passing through the support 10 via third openings 102. The first reflector 11 is then brought against the support 10 and assembly means comprising the first fixing elements 98 configured to assemble the support 10, the first reflector 11 and the second reflector 12 are put in place, these first fixing elements 98 being for example screws.

[0051] According to other embodiments, some of the fastening elements 97, 98, 99 can be replaced by clips made directly in one of the reflectors 11, 12. Clips alone would be less strong and would not provide as reliable a clamping force as screws, but could be combined with screws or other clamping means such as nuts allowing for quarter-turn tightening, mounted on studs made in reflectors 11, 12.

[0052] According to yet another variant not illustrated here, the lighting system 1 comprises a third lighting device juxtaposed to the first or second lighting device. If the third lighting device is juxtaposed to the first lighting device D1, it is then juxtaposed opposite the second lighting device D2, and if the third lighting device is juxtaposed to the second lighting device D2, it is then juxtaposed opposite the first lighting device D1. Thus, the lighting system 1 comprises, for example, a series of reflectors between which supports are interposed. Each of these interposed supports includes elements such as those described with respect to the support 10 of the second lighting device D2, thereby allowing an iterative assembly of lighting devices benefiting from the mechanical properties of the interposed supports.Thus, the invention is not limited to a system comprising two lighting devices but extends to a lighting system 1 comprising a plurality of lighting devices between which supports are intercalated and compressed.

[0053] Thus, the lighting system comprises at least two juxtaposed lighting devices assembled to increase their respective rigidity. Indeed, the compression of the support between the reflectors of the two lighting devices allows the reflectors to benefit from the mechanical properties of the support, thereby considerably increasing their respective mechanical strengths once the lighting system is assembled. This construction of the lighting system reduces its mass and volume while maintaining equivalent mechanical properties compared to more conventional designs. Furthermore, the assembly of the lighting system is facilitated by a sequential assembly of its components and technical solutions that simplify their relative positioning.Thus, thanks to all the functional and structural technical characteristics of the present invention, we have a lighting system that is mechanically resistant, lightweight and compact, these characteristics making it easy to integrate this lighting system into different vehicles.

[0054] The present invention also relates to a vehicle, for example an automobile, comprising the lighting system as presented in this description.

[0055] It should be noted that this detailed description relates to a particular embodiment of the present invention, but in no way does this description limit the scope of the invention; on the contrary, its purpose is to remove any possible inaccuracy or misinterpretation of the following claims.

[0056] It should also be noted that the reference signs in parentheses in the following claims are in no way intended to be limiting; these signs are solely intended to improve the intelligibility and understanding of the following claims and the scope of the protection sought.
