    [0001] FIELD OF THE INVENTION The invention relates to a lighting device of a vehicle using a multi-source optical lens. Lighting devices intended to be mounted in vehicle projectors, exist and have already been the subject of patents. It is possible, for example, to quote patent application US2007 / 0120137, which relates to a multi-source lighting device, comprising a multiplicity of unitary and distinct assemblies. Each assembly comprises a light source which is mounted on a substrate providing current to said source, and a lens associated with said source. All the light emitted by this light source is transmitted to an exit diopter of the lens via a conduit whose cross section progressively increases from said source to said exit diopter. The exit diopter has a D-shape and makes it possible to transmit the light beams coming from the light source, in the same direction. The lighting device described in this document is modular, because it can consist of a variable number of unit assemblies, depending on the lighting requirements encountered. Such a device nevertheless has the disadvantage of implementing several unitary assemblies and therefore several separate lenses, requiring a certain complexity of assembly, and generating additional costs associated with the manufacture of several lenses. A lighting device according to the invention has a character of modularity, through the use of several light sources, while overcoming the disadvantages noted in the state of the art. The invention firstly relates to a piece of transparent material comprising at least two elementary portions each consisting of an entrance surface and an exit surface, each exit surface being focused at the entrance surface of the inlet surface. the same portion, the outlet surfaces being contiguous so as to form an overall output surface of said piece which is integral, the input surfaces being at a distance from one another 3025865 2 being separated by suitable means to prevent that rays from a light source placed at the inlet surface of a portion can pass through the exit face of the adjacent elementary portion. In this way, this piece of transparent material is intended to be used in a light device, in combination with light sources placed at the entrance surfaces, so as to obtain a resulting light beam from the exit surfaces, without any parasitic light interference. In other words, the part separation means thus make it possible to divide said part into several distinct portions 10 constituting dissociated light sources, having no light interaction between them. Depending on the lighting requirements encountered, this part may comprise a variable number of elementary portions, each having their specific structural and optical characteristics. Advantageously, each entrance surface is planar and each exit surface is curved. Advantageously, the exit surfaces of the elementary portions are contiguous, so as to form a resulting output surface of the part, which is continuous. According to one embodiment of the invention, the fact that each exit surface is focused at the entrance surface of the same portion means that there is a horizontal point or segment in the vicinity of the entrance surface. such that a majority of the rays coming from this point or points of the line emerge from the exit surface while being parallel to the same plane. Advantageously, the means are constituted by walls originating at each input surface and extending towards the corresponding output surface. These walls are arranged to reflect the light beams coming from the input surfaces, and not to transmit them to the output surfaces of the adjacent elementary portions. Advantageously, each wall extends towards an edge delimiting the exit surface.
    [0002] Preferably, the elementary portions are aligned, the two input surfaces of the two elementary end portions being bordered by a single wall, and the input surfaces of the other elementary portions being each bordered by two walls. Indeed, each of the two elementary end portions has a single wall to prevent the beams coming from its input surface, to pass through the exit surface of the single adjacent elementary portion. The other elementary portions being flanked by two adjacent elementary portions, therefore require two walls to prevent the beams coming from their input surfaces from passing through the exit surface of said two adjacent elementary portions. Preferably, each wall has a curved profile. Indeed, the walls are not rigorously flat. It is a low amplitude curvature, not affecting the direction of global expansion of said wall.
    [0003] Advantageously, the part has several depressions each delimited by a wall of an elementary portion and a wall of the adjacent elementary portion. In this way, said piece has an optimized geometry so that its weight and its size are as small as possible.
    [0004] Advantageously, each hollow has a rounded bottom. In other words, the two walls of the two adjacent elementary portions delimiting a hollow, meet by means of a curved segment. Preferably, the walls are aluminized. In this way, each of said walls can effectively reflect the light beams from the input surface to converge them to the output surface of the same elemental portion. Preferably, the part is made of a material to be chosen from glass, polycarbonate and PMMA (Polymethyl methacrylate).
    [0005] Advantageously, the exit surface and the entrance surface of the same portion are opposite each other.
    [0006] Advantageously, each exit surface is convex relative to the outside of the room. Preferably, the overall exit surface is convex relative to the outside of the room.
    [0007] The second object of the invention is a light module, comprising a piece of transparent material according to the invention, a substrate and at least two light sources implanted in said substrate, said sources illuminating the input surfaces of two adjacent elementary portions. , the beams coming from an input surface being able to pass only 10 by the exit surface of the same elementary portion, the separation means preventing said beams from passing through the exit surface of the adjacent elementary portion. In this way, such a light module makes it possible to emit a resulting light beam, coming from the exit surfaces, having several components each coming from an elementary portion of the piece of transparent material, said beam being devoid of any spurious signal. due to light interferences between said elementary portions. This module can for example be installed in a vehicle front projector to obtain a code-type lighting, or a day signal of said vehicle. Said module can also be implanted in the passenger compartment of a vehicle to ensure a less intense lighting function, for the attention of passengers. Advantageously, each light source is constituted by a light emitting diode. Such a diode offers a good quality of light beam, while remaining a small size. It is therefore perfectly adapted to a light module according to the invention, the dimensions of which must be limited in order to be, for example, incorporated in a motor vehicle. Preferably, the substrate has an implantation surface of the light sources, said surface having a central advance, so that the light sources placed at the end zones of said surface, are set back from those placed on said advance in relation to the direction of emission of light by said sources. In other words, each light source placed at an input surface of an elementary end portion is further away from the exit surface of the same elementary portion than are the light sources 5 placed at the level of the input surfaces of the intermediate elementary portions with respect to their corresponding output surfaces. In this way, on a motor vehicle, the end light sources will be able to provide intense illumination focusing on the range, while the intermediate light sources will provide spreading wide focus illumination. According to a preferred embodiment of a light module according to the invention, said module has two light sources each placed in an end zone of the implantation surface of the substrate, and three light sources placed at the level of the advanced said five sources being aligned in front view and emitting light in the same direction. In this way, if the module were implanted in a vehicle headlamp, the two end light sources would be designed to provide intense focus-focused illumination, and the three intermediate light sources would provide illumination with a large width.
    [0008] Preferably, the light sources are LEDs comprising at least one light emitting element, at least one light source whose edges of the light emitting element present, in front view, an orientation different from those of another LED. Advantageously, the implantation surface of the substrate has a recess adapted to receive an electronic card. This card will be used to supply power to the light sources of the module. Advantageously, the electronic card is provided with an electrical connector. Advantageously, a light module according to the invention comprises a radiator for cooling the light sources. Preferably, the radiator comprises the substrate.
    [0009] Preferably, the radiator forms a single piece. Advantageously, the radiator is metal. The third object of the invention is a vehicle light device comprising at least one light module according to the invention.
    [0010] Advantageously, a light device according to the invention comprises: a housing intended to be fastened to a vehicle; a closing window of said housing, said light module being housed inside the space delimited by the housing and the housing; closing mirror, the luminous device being arranged in such a way that the rays issuing from said overall exit surface directly reach said closing window. Preferably, the rays emitted by the module at the output of the overall output surface of the module form a portion or the entirety of a lighting beam of the road, signaling, or lighting of the passenger compartment.
    [0011] In this way, it is not necessary to put another optical deflection element or a cover. In other words, the light device may be devoid of a lens, reflector or cover after the overall exit surface. A light module according to the invention has the advantage of implementing a single piece of transparent material, and intended to be used with several light sources, to fulfill a specific lighting or signaling function. Since the transparent part has a compact geometry, said module has the advantage of being compact. It also has the advantage of generating moderate costs, avoiding having to machine several lenses, each dedicated to a particular lighting and / or signaling function. It also has the advantage of being able to produce a great variability of light beams according to the number and the location of the associated light sources, to meet different needs and requirements in terms of lighting. Finally, a light module according to the invention has the advantage of being particularly suitable for a motor vehicle, in which the light beams are necessary, whether at the level of the headlamps to provide a lighting function for the vehicle. road or signaling, or at the passenger compartment to provide lighting for passengers.

Referring to FIGS. 1A and 1B, a light module 1 according to the invention comprises a radiator 2 connected to a substrate 3, an electronic card 4 equipped with an electrical connector 5, five light-emitting diodes 6 which will be called LEDs for the Following the description, a piece 7 of transparent material according to the invention and a housing 8 for protection and maintenance, adapted to grip said transparent piece 7. The housing 8 is fixed to the substrate 3 by means of a first series of screws 9. The electronic card 4 is anchored in the substrate 3 by means of a second series of screws 10. Such a module 1 is intended to come for example, to fix inside a vehicle headlamp. Referring to Figures 2A, 2B and 3, the piece 7 of transparent material according to the invention is solid and is made of PVC (polyvinyl chloride), and acts as an optical lens. This part schematically comprises two lateral lugs 11, 12 and a central body 13 located between said lugs 11, 12 and in position offset with respect thereto. Said body 13 is bordered by two end arms 14, 15, each connected to a tab 11, 12, each of said arms 14, 15 extending in a direction which is perpendicular to that of the tab 11, 12 to which it is connected. The two lugs 11, 12 are strictly aligned, so that the transparent piece 3025865 9 7 can abut against a flat surface, by means of these tabs 11, 12. The body 13 of this part 7 is divided into five parts. elementary portions 16, 17, 18, 19, 20 full, each characterized by an inlet surface 21, 22, 23, 24, 25 and an outlet surface 26, 27, 28, 29, 30.
    [0012] These five portions 16, 17, 18, 19, 20 are substantially aligned in the same direction, which is the one in which the two legs 11, 12 are connected. This transparent piece 7 thus has two elementary end portions 16, 17, materialized by the two end arms 14, 15, and three intermediate elementary portions 18, 19, 20 positioned between said portions 16, 17 of each other. end. The five exit surfaces 26, 27, 28, 29, 30 are joined, to form an overall exit surface of said workpiece 7, which is continuous. These five outlet surfaces 26, 27, 28, 29, 30 constitute the most advanced part of the body 13 with respect to the two lateral lugs 11, 12. The five input surfaces 21, 22, 23, 24, 25 are separated from each other, and are substantially aligned with the two legs 11, 12. Each portion 16, 17, 18, 19, 20 is elongate, the entrance surface 21, 22, 23, 24, 25 and the surface output 26, 27, 28, 29, 30 constituting the two ends of each of said portions 16, 17, 18, 19, 20 along their longitudinal axis. The three intermediate elementary portions 18, 19, 20 each have two walls 31, 32, 33, 34, 35, 36 originating at the inlet surface 23, 24, 25 and extending towards two edges delimiting the outlet surface 28, 29, 30 of the same portion 18, 19, 20. These walls 31, 32, 33, 34, 35, 36, which may for example be aluminized, are intended to prevent the beams produced by a light source placed at an inlet surface 23, 24, 25 of a portion 18, 19, 20, to pass through the exit surface of an adjacent portion. The two elementary end portions 16, 17 have only one wall 37, 38 intended to prevent a light source placed at the level of the input surface 21, 22, of one of them, to irradiate an exit surface of an adjacent elementary portion 30, since each of said end portions 16, 17 has only one adjacent elementary portion. The walls 31, 32, 33, 34, 35, 36, 37, 38 of two elementary portions 16, 17, 18, 19, 20 adjacent meet by means of a curved wall segment. The transparent part 7 thus has a series of four recesses 39, 40, 41, 42 aligned alternately with the five elementary portions 16, 17, 18, 19, 20, each recess being thus delimited by a wall of a portion elementary and by a wall of an adjacent elementary portion. The two inlet surfaces 21, 22 of the two end elementary portions 16, 17 are set back from the inlet surfaces 23, 24, 25 of the three intermediate elementary portions 18, 19, 20. For each of the five portions elementary 16, 17, 18, 19, 20, the average distance between the entrance surface and the exit surface is substantially constant. The inlet surfaces 21, 22, 23, 24, 25 are parallel and the outlet surfaces 26, 27, 28, 29, 30 are rounded in shape. As shown in Figure 5A, the transparent part 7 is not rectilinear. The lateral lugs 11, 12 are parallel and are interconnected by the body 13, which is materialized by a rectilinear segment and inclined with respect to two lugs 11, 12, of an angle less than 10 °. As indicated in FIG. 2A, this piece 7 comprises a right side (DR) and a left side (GA). With reference to FIGS. 1 and 3, the radiator 2 and the substrate 3 constitute a one-piece piece of metal. The substrate 3 is comparable to a thin plate having an implantation face 43 having a recess 44 whose contour is similar to that of the electronic card 4, said recess 44 being intended to receive said card 4. face 43 has a central protrusion 45 partially bordering the recess 44 and contributing to partially enlarge the edge surrounding said recess 44. Referring to Figures 3 and 4, the five LEDs 6 are secured to the face 43 of the substrate 3, which is provided with the recess 44, at a zone 25 outside said recess 44. More specifically, with reference to FIG. 4, the five LEDs 6 are arranged along the edge delimiting the recess 44, three LEDs 6 being placed on the protuberance 45 and the other two LEDs 6 being placed at the face 43 of the substrate 3 located at a lower altitude than that of said protrusion 45. In this way, two LEDs 6 ext dime frame three LEDs 6 intermediate, raised. Each LED 6 has a light-emitting element comparable to an object of square shape and having a small thickness. The five LEDs 6 are rotated differently with respect to the forward direction, ie the transmission direction of the module. In other words, in front view, these LEDs have different orientations. For example in projection on a projection plane located in front of the LEDs and perpendicular to the optical axis or main emission of the light module, these LEDs have different orientations within said projection plane. Thus, two LEDs can be arranged so that the edges of their photoemissive elements have a different orientation in front view. These edges can, in front view, make between them an angle of 45 °. These five LEDs 6 are arranged to emit a light beam in the same direction. Referring to FIG. 3, the transparent part 7 according to the invention is fixed on the substrate 3 so that each of the five LEDs 6 secured to said substrate 3 comes to be positioned at a surface d input 21, 22, 23, 24, 25 of said piece 7. Specifically, the LEDs 6 are found outside the elementary portions 16, 17, 18, 19, 20 of the part 7, so that each LED 6 can send light beams to the input surface 21, 22, 23, 24, 25 with which it is associated, said beams passing through said input surface 21, 22, 23, 24, 25 and then pass through the outlet surface 26, 27, 28, 29, 30 of the same portion. Thus, the walls 31, 32, 33, 34, 35, 36, 37, 38 prevent the light beams emitted by an LED 6 placed at an elementary portion 16, 17, 18, 19, 20, reach to the exit surface 26, 27, 28, 29, 30 of an adjacent elementary portion 16, 17, 18, 19, 20. The elementary portions 16, 17, 18, 19, 20 act separately and autonomous, in order to obtain a resulting light beam, without parasitic interference. the light beams coming from each input surface 21, 22, 23, 24, 25 may either directly reach the corresponding exit surface 26, 27, 28, 29, 30, or may be previously reflected on the walls 31, 32 , 33, 34, 35, 36, 37, 38 before reaching said exit surface 26, 27, 28, 29, 30.
    [0013] Referring to FIG. 1B, once the transparent part 7 has been mounted on the substrate 3, the housing 8 is screwed onto said substrate 3 by partially capping said transparent part 7. This produces a light module 1 compact form, adapted to be inserted in a remote and inaccessible space, such as those that can be encountered in a motor vehicle. FIGS. 5A to 9B illustrate an example of use of a light module 1 according to the invention, by decomposing the resulting light beam, into several components, each derived from an elementary portion 16, 17, 18, 19, 20, said module 1 associated with the corresponding LED 6. In this way, referring to FIGS. 5A and 5B, the end elementary portion 16 located to the left of the module 1 and associated with the corresponding end LED 6, can be used to produce a left-handed lighting. This lighting is rather concentrated and intense.
    [0014] Referring to FIGS. 6A and 6B, the left intermediate elementary portion 18, associated with the corresponding LED 6, can be used to produce horizontally extended illumination to the left. This lighting is rather low intensity and spread transversely to the vehicle. Referring to FIGS. 7A and 7B, the central intermediate elementary portion 19, associated with the corresponding LED 6, can be used to produce horizontally extended illumination to the right as well as to the left. This lighting is rather low intensity and spread transversely to the vehicle. Referring to FIGS. 8A and 8B, the left intermediate elementary portion, associated with the corresponding LED 6, can be used to produce horizontally extended illumination to the left. This lighting is rather low intensity and spread transversely to the vehicle. Referring to FIGS. 9A and 9B, the end elementary portion 17 located to the left of the module 1 and associated with the corresponding end LED 6, can be used to produce a tilted, left-angle illumination 3025865 13 of a angle of 15 ° with respect to a horizontal axis. This lighting is rather concentrated and intense. As clearly shown in FIGS. 5A, 6A, 7A, 8A and 9A, the light beams produced by each LED 6 of the light module 1, pass through only the elementary portion 16, 17, 18, 19, 20 to which said LED 6 is associated, without being able to go to the exit surface 26, 27, 28, 29, 30 of an adjacent elementary portion 16, 17, 18, 19, 20. It follows that a light module 1 according to the invention , is able to produce a resulting light beam, which is clear and precise, because devoid of any light beams 10 parasitic due to light interferences between the different elementary portions 16, 17, 18, 19, 20 of said module 1. Although the LEDs all bear the same reference in the description, in this case the number 6, they can naturally have different structural, geometrical and luminous characteristics within the same light module 1, said LEDs 6 being chosen according to the needs specific in lighting.
