    [0001] The present invention relates to a lighting and / or signaling device comprising a light-emitting diode and a light guide adapted to conduct light from the diode. It relates more particularly to means for fixing the diode with respect to the light guide.
    [0002] The invention finds particular use in projectors or motor vehicle lights, in which the use of light-emitting diodes becomes more and more common. Lighting modules are thus known for a motor vehicle comprising a housing fixed to the vehicle structure and closed by a projection window, a signaling and / or light-emitting diode lighting device being housed inside the module. . This type of signaling and / or lighting device comprises an optical guide disposed opposite the light emitting diodes to achieve the desired guidance of the light. Means for fixing the light guide with respect to the light-emitting diode are to be provided so that, on the one hand, the required distance between these two components is respected, and on the other hand the diode is correctly centered with respect to the face of the light-emitting diode. entrance of the light guide. It is indeed necessary that all the rays emitted by the light emitting diode enter the light guide by breaking, so as to limit the loss of efficiency of the lighting and to avoid oversizing the diodes to obtain a desired photometric performance . In patent documents WO 12098123 and EP 2,479,487, tubular light tubes are disclosed at the end of which a light-emitting diode is fixed, so that all the light rays coming from the diode enter by refraction into the light-emitting diode. the light guide to an exit face determined so that the rays come out of the projector at the desired inclination. In these documents, embodiments are disclosed in which the tubular light guide is attached to a support piece which has, on the one hand, means for receiving the guide and, on the other hand, means for receiving a card. printed circuits, on which are arranged both a light emitting diode and electronic circuits adapted to supply power to the light emitting diode.
    [0003] The stacking of these three parts generates a congestion that can be detrimental in an area where, for aesthetic issues or issues of regulatory standards, the concept of compactness is important. In this context, the present invention proposes a lighting and / or signaling device as described above, in which the fixation of the light guide with respect to the position of the light-emitting diode is optimized. The invention proposes a device comprising a light-emitting diode and a light guide adapted to conduct light coming from said diode, as well as means for fixing the diode with respect to one end of the light guide to ensure the position of a light-emitting diode. input face of the guide facing the diode, characterized in that the light guide carries male fastening means adapted to cooperate with female fastening means carried by a plastic part carrying the light emitting diode and electrical circuits made directly on said plastic part in the immediate vicinity of the diode. Thus, in particular by the realization of a molded interconnected device (so-called MID technology, "Molded Interconnect Device"), it is possible to integrate the electrical circuits directly into the plastic part which also carries female means to cooperate with a male end integral with the guide. from light. It can be seen that the number of parts for setting up the light guide in front of the diode is reduced, which reduces the rib chains and avoids a corresponding dispersion of the light flow. It is not necessary to oversize the diode to compensate for this dispersion. In the case of embodiment of the device by a specific MID technique, called "Hot Embossing", it is expected that the plastic part carries the diode and the corrective tracks in a flat central portion.
    [0004] Advantageously, the presence of an intermediate piece has been replaced by a modified light guide and a modified electrical circuitry without, however, complicating the design and manufacture of the light guide since only a male part, serving to position the the female part of the clip, is necessary protruding from the guide. This ensures the positioning function without degrading the optical performance of the light guide and without complicating its manufacture, the difficult demolding of parts of the prior art can penalize their optical function. According to various secondary features of the invention: the male part of the fixing means is formed by a plate disposed at the end of the light guide and protruding laterally from the guide to form protruding means adapted to cooperate with the means of female fixation carried by the plastic part. The plate is made of a transparent material that can guide the light rays from the light-emitting diode. Advantageously, this plate forming the male part of the fixing means is integral with the light guide; - The plate forming the male part of the fixing means has a variable thickness, in particular by the fact that the thickness is reduced in the center of this plate, right of the light guide and the diode. Thus, it is ensured that the light emitted by the diode passes through a minimum of material before entering the tubular portion of the light guide, and that the path of the light beam is the least impacted possible. The male part can advantageously integrate a collimation structure like Fresnel lens; the plastic support part of the diode has a planar central receiving part of the diode and electrical circuits as well as peripheral parts which protrude around said flat central part and which form said female fixing means; - The diode support plastic part is obtained by hot stamping, incorporating into the plastic material a metal sheet on which are formed electrical circuits for supply and control of the light emitting diode. Advantageously, with this technique of realization, a greater thickness of metal is provided centered around the light emitting diode; the support piece can also integrate the connector function, either by a card edge connector technique, or with any type of connector inserted in force, with the electrical contacts of the connector electrically connected, by a conductive glue or a solder paste for example, the electrical circuits made on the plastic material of said support piece; - The diode support plastic part is made of conductive polymer material, that is to say with a conductivity greater than 1 W.m-l.k-1. By way of example, the material may be a polyamide, polypropylene, or polystyrene, loaded with thermally conductive fibers; the plastic support piece may comprise a through-hole adapted to receive a diode mounted so that the fastening elements and the connection of the diode are attached to one face of the support piece opposite to the direction of emission of the rays; luminous output of the diode; - the electrical circuits can be covered by a varnish, to protect them. The invention also relates to a motor vehicle comprising a lighting and / or signaling module, in which at least one light guide and a light emitting diode are housed for light emission and guiding, characterized in that the guide and the diode are fixed relative to each other in a device as described above. According to different characteristics, the female part of the fixing means is made by a plastic part that is brought back to the module or this female part is directly carried on the housing of a lighting module and / or signaling of 'a motor vehicle. The invention and the advantages thereof will be detailed in the detailed and nonlimiting description which follows, and which will be made with reference to the appended drawings, among which: FIG. 1 is a perspective view of a device of FIG. lighting and / or signaling according to the invention, comprising in particular a tubular light guide and means for fixing a light-emitting diode disposed at one end of this guide; FIGS. 2 and 3 are perspective views of the male and female parts of the device illustrated in FIG. 1, according to a first embodiment of the invention; - Figures 4 and 5 are perspective views and side section of the assembly of the two parts shown in Figures 2 and 3; and FIGS. 6, 7 and 8 are views similar to FIGS. 2, 3 and 4 for a second embodiment of the invention. As illustrated in Figure 1, the lighting and / or signaling device comprises a tubular light guide 2, at a proximal end 4 which are arranged means 6 for fixing a light source. This device is particularly adapted to be placed in the housing of a lighting and / or signaling module of a motor vehicle, the light emitted by the light source being received and driven by the light guide from a surface of the light source. input 8 opposite the source to an exit face formed by a surface of revolution of the tubular guide. As is known moreover, the guide comprises a reflection face 10 of the current rays in the guide, comprising, for example, prisms which return the rays towards the exit face at an incident angle allowing their refraction out of the guide, and out of the module for performing the desired lighting and / or signaling function.
    [0005] The light source is formed by a light-emitting diode 12, which is carried by a plastic part 14 also carrying electrical circuits 16 for supplying and controlling the diode, represented for example by a bold line in FIG. 5, and possibly covered with protective care by a varnish. The support member 14 and the guide 2 are adapted to cooperate to ensure the relative position of the diode relative to the entrance face of the light guide. More specifically, they each have suitable shapes to perform on the one hand guide in position of the guide in the plastic part to an active position in which the input face of the guide is located in line with the diode, and to achieve on the other hand the locking of the guide in this active position. According to the invention, the light guide has male fastening means adapted to cooperate with corresponding female fastening means carried by the plastic diode support piece, so that it is the guide which is inserted and blocked in position in the plastic part. The light guide 2 has at its proximal end 4 a plate 18 extending in transverse projection tubular portion of the guide. The guide extends along a predetermined curvilinear axis) (X ', and the plate extends transversely to this predetermined direction .The guide and the plate are made in one piece, made of transparent polymer, of the polycarbonate (PC) type. or polymethylmethacrylate (PMMA), or any other suitable polymer, that is to say in a transparent material that can be traversed by the light rays emitted by the diode.
    [0006] The plate protrudes laterally from the guide and thus forms prominent means which will be detailed later as the male fastening means in the description of two embodiments. In general, the corresponding female fixing means are carried by the plastic part and peripheral parts 20 of this plastic part, which rise projecting on either side of a flat central part 22 which carries the diode 12 and the electrical circuits 16 centered around the diode. The plastic support piece also comprises a housing 24 adapted to receive at least partly a connector 25, visible in Figures 7 and 8, which is connected to the electrical circuit made in the plastic material of the support piece. The particular production process according to the invention of the plastic part will be described below, and in particular the hot stamping technique used to directly inject the electrical circuits into the plastic thickness of the support piece. A first embodiment of the means for fixing the light guide with respect to the light-emitting diode will now be described with reference to FIGS. 2 to 5. As illustrated in Figure 2, the plate forms a flange at the end of the light guide. The flange has a diameter greater than the diameter of the tube so that, as previously described, the plate protrudes laterally from the tube. On the circular periphery of this plate, two notches 26 are arranged diametrically opposite. As illustrated in FIG. 3, the diode support piece has the shape of a housing 28 with a bottom wall having the flat central portion 22 and peripheral portions 20 which protrude around this wall. background.
    [0007] The peripheral portions comprise two lateral longitudinal walls 30, which form transverse stops for the guide plate and which thus guide longitudinally the insertion of the plate, as well as a transverse end wall 32. At the opposite of this wall transversal, the absence of peripheral parts allows the insertion of the plate in the support part. The longitudinal walls have a sectional variation between the thicker base and the free end, opposite the bottom wall, finer. The thicknesses are determined in such a way that the distance between the bases of the longitudinal walls is smaller than the diameter of the plate at the end of the guide, preventing insertion at this level of the light guide. This avoids when inserting the guide to hit the diode. The guide is inserted higher and the shoulder of the longitudinal walls forms a vertical guide edge 34 on which can rest the end plate of the guide. It can be seen that the side walls and the shoulder form a guide path for this plate. Two posts 36 protrude outwardly from the side walls, towards the inside of the diode support piece, so as to narrow the passage for the plate. The user must force on the plate during insertion to allow passage to the plate, deforming the plastic part by spacing the side walls. The light guide is in the active position when the lateral uprights penetrate the notches formed in the plate. It is understood that, so that the user does not go beyond this active position during the force insertion of the guide, the plate abuts against the transverse end wall. This transverse end wall comprises substantially at its center a vertical abutment means 38 protruding from the wall towards the inside of the support piece, and disposed at a distance from the bottom wall slightly greater than the addition of the height of the shoulder relative to the bottom wall and the thickness of the plate extending the light guide. Thus, when the guide is inserted into the housing by sliding the plate against the shoulders of the side walls, it is found in its active position housed under this vertical abutment means. The plate, and the associated guide, are thus locked in position, on the one hand in the plane of the bottom wall by the cooperation of the uprights of the support piece and the notches of the plate, and on the other hand in the third dimension, perpendicular to the bottom wall, by blocking the plate between firstly the stop means carried by the end wall and secondly the shoulders of the side walls. A second embodiment illustrated in FIGS. 6 to 8 is now described. The lighting and / or signaling device according to this second embodiment has a structure close to that of the device described above. In accordance with what has been specified generally for the invention, and taking again the numerical references used for the description of the first embodiment, the light guide 2 has at its end a plate 18 forming adapted male fastening means to cooperate with female fastening means carried by a plastic diode support piece 14, on which electrical circuits for supplying and controlling the diode are made, here as a non-limiting example at a part of However, the devices differ on structural details such as the shape of the plate and the shape of the support piece. As illustrated in Figure 6, the plate has a trapezoidal shape disposed at the end of the light guide. The small base of the trapezium forms a tenon pointing towards the outside of the guide. The side walls 42, connecting the bases of the trapezium, are machined near the large base to form stop walls 44 when the guide is in position in the diode support part. As illustrated in FIG. 7, it is observed that the diode support part also has the shape of a housing 28 with peripheral parts, among which two lateral longitudinal walls 30 and a transverse end wall 32. The wall transverse end comprises a central opening 46 of shape adapted to allow passage to the post of the plate extending the light guide. We then have a type of tenon / mortise cooperation that allows mounting of the guide in the diode support piece with polarizing means to ensure the correct orientation of the exit face 10 of the light guide. The edges of the wall defining the central aperture form vertical abutment means to prevent the release of the plate from the workpiece perpendicular to the plane defined by the bottom wall. In the insertion direction of the plate in the support piece, stop means specific to this embodiment are provided to define the active position of the light guide. In the direction of insertion, the plate abuts against the transverse end wall. In the opposite direction, the abutment walls 44 formed on the side walls of the plate cooperate with shoulders 48 arranged at the free end of the lateral longitudinal walls. As before, the user must force on the plate during insertion to allow passage to the plate, deforming the plastic part by spacing the side walls. The light guide is in the active position when the side walls of the plate have exceeded the shoulders arranged at the free end of the longitudinal side walls. It can be seen in FIGS. 4 and 8 according to the embodiment, that when the light guide and the plastic part are assembled so that the guide is in its active position, the position of the light guide opposite has been ensured. of the light-emitting diode with a minimum of parts.
    [0008] The dimension of the axial stacking of these parts, along the mechanical axis of the diode, is minimal, defined mainly by the thickness of the bottom wall carrying the light-emitting diode and by the thickness of the plate extending the light guide. light. It will be understood that it is possible, without departing from the context of the invention, to provide other forms of the plate extending the light guide and the receiving housing of this plate, since the light guide carries means of male fasteners adapted to cooperate with female fastening means carried by a plastic part carrying the light emitting diode and electrical circuits, directly made on the plastic material of the guide support piece. For example, in a variant not shown, the thickness of this plate is variable, in particular in that a smaller thickness is provided in the direct extension of the tubular guide. When the light guide is in the active position, this smaller thickness is at the right of the diode so that the light rays coming from the diode to enter by refraction in the tubular guide have a less significant thickness of transparent material to pass through. Also, it will be possible to provide the diode support plastic part, either by a housing that is then fixed on the lighting module and / or signaling (as is the case in the embodiments illustrated on the figures), or directly in the thickness of the housing forming the lighting module and / or signaling in which the device according to the invention is installed. Another variant consists of a specific arrangement of the diode, mounted according to a so-called "reverse-led" technique, in which the carrier plate carrying electrical circuits has a hole enabling the diode to be placed in position through this hole, the dome of the diode being oriented on the side of a first face of the support plate while the electrical contacts of the diode are arranged on the side of the opposite face of the support plate, this opposite face carrying the conductive tracks to be connected to the diode.
    [0009] The method of obtaining the plastic part, in which electrical circuits are injected, is now described to form a molded interconnected device (MID). The method is particular here in that it uses a technique of hot stamping, technique called "hot embossing". The hot stamping technique used here consists of producing a metal sheet, depositing this sheet on the part of the support piece intended to carry the conductive tracks, if necessary with a heat activatable glue placed between the sheet and the support piece, and in a hot stamping step of the plastic part to press the sheet thereon. A preliminary step is to give the sheet the desired thickness of metal, and possibly varying thicknesses. When this sheet is deposited on the support, a hot press is applied against the sheet, under temperature conditions adapted to plastically deform the material of the support piece. The face of the press brought into contact with the metal sheet has ribs which project from this face in a corresponding arrangement to the arrangement of the conductive tracks that it is desired to integrate on the support plate. The hot deformation of the support plate generates the formation of housing shapes complementary to those of the ribs projecting from the press. The metal layers are pushed into these housings and the integrated metal in the volume of the support plate forms conductive tracks.
    [0010] The choice of hot stamping makes it possible to deposit a thick layer of metal in the flat part of the female part. This is particularly interesting in the case, common in the automotive industry, for example, where a diode of high power is expected and therefore a demanding thermal management of the diode and more heat dissipation. Advantageously, thanks to this hot stamping technique, it is easily possible to center the extra thickness of metal around the diode. As just described, the device according to the invention finds particular application in a lighting module and / or signaling of a motor vehicle. It can be implanted in the vehicle for indoor or outdoor lighting. This device has the advantage of an assembly of the guide and the diode support in which a male fixing part is carried by the guide, so that it is easier to obtain by molding than if it bore female parts, hardly extrudable. In this context, the support piece is advantageously a molded interconnected device, so as to make possible the dual function of the support part, namely the support of the electrical circuits and the support of the diode. This ensures the position of the light guide relative to the diode, so as to inject a maximum of light in the guide, and with a smaller number of parts than in the state of the art, and with parts simple to obtain by molding. It is thus possible to propose an optical module whose dimensions are controlled and in which it is not necessary to oversize the diode to obtain the quantity of light emitted.
