    "Light module for a motor vehicle, and lighting and / or signaling device provided with such a module"
    The present invention relates in particular to a light module for a motor vehicle, and to a lighting and / or signaling device provided with such a module.
    A preferred application relates to the automotive industry, for vehicle equipment, in particular for the production of devices capable of emitting light beams, also called lighting and / or signaling functions, which generally meet regulations. For example, the invention can allow the production of a segmented type light beam, in particular for signaling and / or participation in lighting functions at the front of a vehicle. It can be used to produce a near field beam. A segmented beam is a beam whose projection forms a mark made up of beam segments, each segment being capable of being lit independently.
    Signaling and / or lighting lights for motor vehicles are light devices which include one or more light sources and lens which closes the light. In a simplified manner, the light source emits light rays to form a light beam which is directed towards the ice in order to produce an illuminating surface which transmits light outside the vehicle. These functions must meet regulations in terms of light intensity and visibility angles in particular. The known lighting and signaling modules have hitherto been designed to emit, for example:
    - a dipped beam, directed downwards, also sometimes called a code beam and used in the presence of other vehicles on the road;
    - a main beam without cutoff, and characterized by maximum illumination in the center line of the vehicle;
    - a light beam for foggy weather, characterized by a flat cut-off and a large illumination width;
    - a signaling beam for city traffic, also called city lamp.
    Recently, technologies have been developed to produce a pixelated beam to perform lighting functions. Particularly known from patent publication EP 2306075 A2 is a lighting device comprising a plurality of light sources constituted by light-emitting diodes each emitting in the direction of an optical element in the form of a waveguide, an output diopter of which projects a individual beam at the front of the vehicle. This forms a plurality of illumination units which can be controlled so as to produce the desired beam shapes.
    However, for certain beams, and in particular for the dipped beam, a specific light distribution is sought which the existing light modules fail to achieve.
    The present invention aims to remedy at least in part the drawbacks of current techniques.
    The present invention relates, in one aspect, to a light module for a motor vehicle configured to produce an output beam, comprising at least a first row of first illumination units configured to produce a first output beam, each first illumination unit comprising a first light source and a first optical element configured to produce a first unit beam from light rays coming from the first light source, characterized in that the first optical element of each of the first illumination units is configured to produce:
    - A first total internal reflection of the rays from the first light source so as to form a reflected beam of collimated rays;
    - a second total internal reflection of the collimated rays so as to generate the first unitary beam.
    According to another aspect, the present invention also relates to a lighting and / or signaling device for a motor vehicle equipped with at least one light module indicated above, and preferably at least two modules.
    Advantageously, the first output beam can be an effective complement to another beam, or even several.
    The present invention also relates to a vehicle equipped with at least one module and / or a device according to the present invention. In particular, two devices can be used which are spaced laterally at the front of the vehicle.
    According to a particularly advantageous embodiment, the first optical element comprises a waveguide configured to produce the first internal reflection and the second internal reflection. The guide is advantageously followed by a lens forming the outlet of the optical element.
    In this way, the optical processing with internal total double reflection is carried out in a single optical element.
    Advantageously, the guide comprises a first reflection surface receiving the rays coming from the first light source from an input diopter of the guide and producing the first total internal reflection in the direction of a second reflection surface receiving the collimated rays and producing the second internal total reflection to generate the first unitary beam.
    Optionally, the first surface and the second surface are offset in a height direction of the module.
    Without impacting the lateral dimensions of the module, this arrangement provides a path of the light rays in the guide long enough to undergo the two reflections.
    Preferably, the first surface is located above the second surface in the height direction of the module.
    According to a nonlimiting case, the second reflection surface is a continuous surface. It preferably has a curvature with a constant radius.
    According to a nonlimiting embodiment, the first optical elements form an assembly originating from a single piece made from a single material.
    Advantageously, the continuous surface is common to the guides of each of the first illumination units
    Preferably, this surface can correspond to a guide slice which extends laterally in a manner common to all the illumination units.
    According to an example, the second internal reflection is configured to spread the first unitary beam in a lateral direction, perpendicular to a direction in height of the module.
    In this way, the discretization effect of the unitary beams tending to isolate the projected unitary beams from one another is limited so that less illuminated transition zones are visible. On the contrary, the invention produces a sufficient overlap of the unitary beams in the lateral direction so that the transition between them is softened.
    Optionally, the second internal reflection is configured to generate a decrease in brightness towards the bottom of the first unitary beam.
    This arrangement is particularly advantageous in the case where the exit beam participates in a low beam function, by forming a near field beam. As explained in detail below, in such a situation, it is sought to reduce the illumination as close as possible to the vehicle and to increase it towards the breaking zone. While such a variation in light intensity is currently impossible using segmented beams, the present invention provides an optical treatment in two reflection phases which allows this variation in intensity of illumination according to the height of a beam.
    Advantageously, the first output beam is a field beam close to a low beam.
    In a preferred embodiment, the module comprises a second row of second illumination units configured to produce a second output beam, each second illumination unit comprising a second light source and a second optical element configured to produce a second beam unit from light rays from the second light source.
    It is thus possible, within the same module, to produce or participate in producing another lighting function or to produce or participate in producing a beam complementary to the first output beam generated by the first illumination units.
    Preferably, the width of the first unit beams is equal to twice the width of the second unit beams.
    With this arrangement, the number of light sources to be used for the first output beam is reduced and a higher resolution is preserved for the second beam.
    Optionally, the second output beam is a low beam cut-off beam.
    This context advantageously corresponds to the case mentioned above in which the first output beam is a near field beam intended to be projected mainly or entirely below a cut-off line and in which the second output beam and a beam of complementary cut so that the result of the two beams forms a low beam function.
    Optionally the module also comprises at least a third row of third illumination units configured to produce a third output beam, each third illumination unit comprising a third light source and a third optical element configured to produce a third unitary beam from of light rays from the third light source. Preferably, the third exit beam is a road complement beam. This third beam can be projected simultaneously with the first output beam, and possibly with the second output beam, so as to produce a more extensive illumination in height according to the main beam function. The first exit beam can be used to illuminate the part close to the road relative to the vehicles while the third exit beam illuminates the part situated above the cut-off line. The second beam can complete the illumination. The invention may have several third rows of third illumination units each configured to produce a third output beam; adding rows increases the height of illumination from the third beams.
    In a preferred embodiment, the module is configured to project a light beam into the front of a motor vehicle.
    Other characteristics and advantages of the present invention will be better understood with the aid of the exemplary description and of the drawings among which:
    - Figure 1 shows a first perspective view of a pair of modules according to an embodiment of the invention;
    - Figure 2 shows another perspective view of the embodiment of the invention of Figure 1;
    - Figure 3 shows a front face of a light module according to the invention and Figure 4 illustrates the rear face;
    - Figure 5 shows a possibility of distributing light sources in a module;
    - Figure 6 shows schematically possibilities of projection of unit beams produced by illumination units present, in this example, in two light modules used in conjunction;
    - Figure 7 reveals a schematic section of an optical part of a light module with the path of certain rays.
    Unless otherwise specified, technical characteristics described in detail for a given embodiment may be combined with technical characteristics described in the context of other embodiments described by way of example and not limitation.
    In the characteristics set out below, the terms relating to verticality, horizontality and transversality (or lateral direction), or their equivalents, are understood in relation to the position in which the lighting module is intended to be mounted in a vehicle. The terms “vertical” and “horizontal” are used in the present description to designate directions, in an orientation perpendicular to the plane of the horizon for the term “vertical” (which corresponds to the height of the modules), and following an orientation parallel to the horizon plane for the term "horizontal". They are to be considered in the operating conditions of the device in a vehicle. The use of these words does not mean that slight variations around the vertical and horizontal directions are excluded from the invention. For example, an inclination relative to these directions of the order of + or - 10 ° is considered here as a minor variation around the two preferred directions.
    The module of the invention incorporates at least one row of illumination units making it possible to generate a segmented type beam, but also preferably ensures the projection of at least one other beam, by means of at least another row of lighting units. The module of the invention can therefore be complex and associate several types of illumination units which may also optionally share components.
    In the context of the invention, the expression “passing beam” is understood to mean a beam used during the presence of crossed and / or followed vehicles and / or other elements (individuals, obstacles, etc.) on or near the roadway. . This beam has a descending mean direction. It can possibly be characterized by an absence of light above a plane inclined by 1% downwards on the side of the traffic in the other direction, and by another plane inclined by 15 degrees upwards relative to to the previous one on the traffic side in the same direction, these two plans defining a cut in accordance with European regulations. The purpose of this top down cutoff is to avoid dazzling other users present in the road scene extending in front of the vehicle or on the side of the road. The passing beam, formerly from a simple headlamp, has undergone changes, the passing function being able to be coupled with other lighting characteristics which are still considered as passing beam functions within the meaning of the present invention .
    This includes the following functions:
    - AFS beam (abbreviation for "Advanced Frontlighting System" in English), which notably offers other types of beams. These include the so-called BL (Bending Light in English for cornering lights) function, which can be broken down into a so-called DBL (Dynamic Bending) function
    Light in English for mobile cornering light) and a function called FBL (Fixed Bending Light in English for fixed cornering light);
    - beam says Town Light in English, for city lighting. This function widens a low beam type beam while slightly reducing its range;
    - bundle known as Motorway Light in English, for highway lighting, performs the highway function. This function ensures an increase in the range of a low beam by concentrating the luminous flux of the low beam at the level of the optical axis of the headlamp device considered;
    - beam says Overhead Light in English, for portal light. This function modifies a typical low beam so that signaling gantries above the road are satisfactorily lit by the low beam;
    - beam known as AWL (Adverse Weather Light in English, for bad weather light).
    The low beam has a differentiated lighting area, the objective of which is to avoid dazzling drivers of crossed vehicles. In particular, the low beam comprises an illuminated zone below the cut-off line, substantially at the height of the horizon line 36, this zone extending laterally on either side of the vehicle covering a sector wide angle. This zone corresponds to a field close to the vehicle. It is however desirable that the low beam also illuminates further ahead of the vehicle, that is to say above the horizon line 36, to provide better visibility to the driver. Therefore, to meet the objective of glare-free at the same time, the lighting area above the horizon line 36 is limited laterally to limit discomfort for crossed vehicles. In the context of the invention, the first output beam 33 can be used to produce the near field beam while a second output beam 34 can be generated in addition to form the cut-off beam. Thus, in this case, the first exit beam 33 is essentially projected below the horizon line 36 while the cut-off beam completes it in a laterally limited portion extending above the horizon line 36.
    Optionally, the invention can also be used to produce a driving beam. The function of the basic driving beam is to illuminate the scene in front of the vehicle over a wide area, but also over a considerable distance, typically around two hundred meters. This light beam, by its lighting function, is mainly located above the horizon line. It may have a slightly ascending optical axis of illumination, for example.
    The device can also be used to train other lighting functions via or outside of those described above.
    FIG. 1 shows an embodiment of the invention comprising two light modules 1. Although this is not limiting, the modules 1 may be identical and spaced laterally from one another, in particular by means of a wall of separation 3 which extends towards the front of the modules 1. The invention potentially includes a plurality of modules each making it possible to emit at least one type of unitary beams. They are preferably juxtaposed, that is to say arranged in a horizontal alignment direction. The term module does not mean that modules are necessarily completely separate organs; they simply understand themselves as separate beam-forming bodies; they can share common parts, such as a support, projection optics or electronic, control elements for example. In addition to light modules 1, the device of the invention can integrate modules of other types for carrying out other functions.
    Each light module 1 comprises, in the case shown, a support 10 carrying an optical unit 14 and a printed circuit card comprising means for controlling the lighting of the light source which can be carried by the card itself. The light sources are each positioned so as to generate a light flux entering the optical unit 14 from which a light projection results, here in the direction of a field optical element 4 (which may be a biconvex lens) then of a projection optical element 2 (also preferably a lens). The latter is preferably common to the various modules 1.
    In a manner known per se, light sources are advantageously used. In general, the present invention can use light sources of the light-emitting diode type also commonly called LEDs. It can possibly be organic LED (s). In particular, these LEDs can be provided with at least one chip using semiconductor technology and capable of emitting light of intensity which is advantageously adjustable according to the lighting and / or signaling function to be performed. Furthermore, the term light source here means a set of at least one elementary source such as an LED capable of producing a flux leading to generate at the output of the module of the invention at least one light beam. In an advantageous mode, the output face of the source is of rectangular section, which is typical for LED chips.
    Preferably, as shown in Figure 5, the light sources are organized in rows. In particular, a first row of first light sources 21 is shown, each serving to produce a first unit beam 31 in conjunction with a first optical element 11, the assembly forming a first illumination unit. A second row of second light sources 22 also appears, each serving to produce a second unit beam 32 in conjunction with a second optical element 12, the assembly forming a second illumination unit. Finally, a third row of third light sources 23 is associated with third optical elements 13 to produce third unitary beams 33, the assembly forming third illumination units.
    In a preferred case corresponding to the illustrations, the optical elements 11, 12, 13 have waveguides and lenses and preferably microlenses. The waveguides provide a phase of propagation of light in the optical element from an input face and by producing internal reflections. The lenses receive the light thus propagated to project it towards the front of the optical element. Preferably, a guide and a lens form a couple in a single piece of which they each constitute a portion. The elements 12 and 13 are lenses and preferably microlenses.
    Each microlens advantageously has an outlet face whose dimensions are greater than or equal to once the dimension of the diode and less than or equal to five times the dimensions of the diode with which it is associated. They are generally in an order of millimeter magnitude. Thus for example, for an individual light-emitting diode (LED) whose emitting surface is 1 mm on one side, the dimensions of the exit face of the associated microlens will be written in a square with a maximum of 5 mm on one side. In addition, these elements can be formed from a single optical unit 14 of which a front face appears in FIG. 1 and a rear face appears in FIG. 2. It can be a part coming from a single optical material, for example poly methyl methacrylate. The optical elements of a row considered are preferably juxtaposed edge to edge in the width direction of the beam to be produced
    Figures 3 and 4 show more specifically an embodiment of the optical elements 11, 12, 13. In this context, the first optical elements 11 have guides and lenses juxtaposed so as to form a row. The orientation of this row is preferably directed perpendicular to the optical axis and preferably parallel to the horizon line. They each comprise, at the level of the guide, a first reflection surface 111 here in the form of a surface of the envelope of the lens which has a convex curvilinear profile. FIG. 4 shows, by the rear face of the optical unit 14, the upstream part of the first optical elements 11, with in particular a second reflection surface 112. The latter is here a continuous surface, in the form of a bevel extending in the direction lateral, also advantageously horizontally. There is also an output diopter 113, at the level of the lens of the optical element, through which the light rays exit from the first optical element 11.
    A second row of optical elements 12 is also visible, through the downstream face of the optical unit 14 in FIG. 3, making it possible to view the exit face of the rays of the optical element 12 and, in FIG. 4, through the upstream face of the optical unit 14, showing the entry face of the rays of the optical element 12.
    Equivalently, the optical elements 13 are organized in rows as before.
    It will be noted from FIGS. 3 to 5 that it is not necessary for the number of illumination units to be identical between the first, second and third units. Furthermore, it appears in this embodiment that the width dimension of the first illumination units is greater than that of the second illumination units, and potentially than that of the third illumination units. In the example, the width of the first lighting units is double that of the other units. This results in a greater width of the first optical elements 11 and in a greater spacing between the first sources 21. In fact, the resolution of the first output beam generated by the association of the first illumination units usually does not require a resolution as high as that of the second output beam, in the context of an application to the formation of a near field beam by the first output beam and to the formation of a cut beam by the second beam exit.
    Preferably, the different rows of illumination units are superimposed.
    FIG. 6 shows examples of projection of unitary beams making it possible to produce output beams when they are combined. It will be noted that the image of the light sources is reversed in this embodiment of the modules, the first unit beams 31, for example, being projected downwards while the first row of sources 21 is positioned towards the top of the module.
    In the upper part of Figure 6, there is shown a projection of all the first unit beams 31 and second unit beams 32 achievable with a first module 1. Note the width of the first unit beams 31 equal to twice that second beams 32. Note also the position of the first unit beams 31, below the horizon line 36. Obviously, a slight overlap is possible, in particular to ensure a smooth transition with the second unit beams 32. The latter are at least mainly located above the horizon line 36. The unitary beams 31, 32 are organized around a vertical median axis 35.
    The intermediate part of FIG. 6 shows a projection of all the first unitary beams 31 and the second unitary beams 32 achievable with a second module 1. The horizon line 36 and the median axis 35 are also presented therein. to visualize the relative position of the beams produced by this second module 1 relative to those produced by the first module 1. In particular, there is a lateral shift of the beams produced by the two modules 1. With regard to the second beams 32, this provides a step for defining a smaller cutting side edge 37 (potentially divided by two). FIG. 6 shows this principle of reduction of the pitch by the dimensions “p” corresponding to the offset pitch of the second beams. For the first beams 31, this offset allows the first beams 31 to overlap, softening the transitions between the unitary beams emitted by the two modules. Advantageously, there is no vertical offset between the beams emitted by the two modules 1. The latter therefore make it possible, when they are ordered in an equivalent manner, to increase the overall light intensity.
    The lower part of FIG. 6 is an example of output beams resulting from the control of two modules 1. In this case, all of the first unit beams 31 are emitted, by switching on all the sources 21, so producing the first output beam 33, which in the example is a near field beam. A part of the second unitary beams 32 is also active, by switching on a selection of sources 22, so as to produce the second output beam 34. It is understood from FIG. 6 that the selection of sources 22 corresponds to a plurality of first sources juxtaposed; by avoiding the ignition of all of the second sources 22, the illumination is confined above the horizon line 36 of a desired sector, avoiding dazzling a crossed vehicle. It should be noted that, advantageously, the lighting device also comprises means for controlling the lighting of the LEDs, in particular for the second row of second light sources 22, to a sensor of a trajectory parameter of a vehicle automobile. The sensor advantageously provides an angle of rotation of a steering wheel of the motor vehicle, the trajectory parameter indicating a deviation from a road on which the vehicle is traveling relative to a straight line, such as, in particular, a turn. Thus, the present invention has the advantage of being able to generate a light beam for low beam, the cutoff of which follows the trajectory of the vehicle on a winding road, due to the beam being discretized into portions corresponding to the second unitary beams 32.
    Figure 7 shows in detail the path of light rays from light sources. As far as the first illumination units are concerned, each first source 21 has an emission face through which emitted beams 24 enter the first optical element 11, via an input face of the latter. This entry face is shown planar in FIG. 7 for simplification but it is advantageously slightly convex so as to produce a bulge in the direction of the source, this bulge being preferably centered on the median axis of emission of the source. The rays reach the first reflection surface 111 which is here positioned opposite the face of the source 21. Advantageously, the first reflection surface 111 is configured to collimate the rays 25 and to direct them, in the form of rays reflected 26, towards a second reflection surface 112. According to the invention, the reflections which take place in the first optical element 11 are total internal reflections; the angles and the material indices are therefore configured to produce these reflections. After impact on the second reflection surface 112, the reflected rays 27 propagate in the direction of an exit diopter 113 to produce the first unitary beam 31. Advantageously, the diopter 113 is convexly convex, and possibly of portion shape. sphere, so as to spread the beam 31, in particular in the lateral direction to produce good homogeneity of illumination of the plurality of beams 31 emitted concomitantly. In addition, the optical element 11 is advantageously configured to produce a decrease in illumination in the beam 31, downwards; the illumination is maximum at the level of the horizon line 36.
    FIG. 7 also schematically shows the generation of a second unitary beam 32. Emitted by a second light source 22, one exit face of which is placed opposite a first optical element 12, the light passes through the optical element 12 until reaching an exit diopter of the latter, to generate the beam 32. As in the case of optical element 11, the exit diopter of element 12 can be convexly convex, and possibly in the shape of a portion of a sphere, so as to produce a desired spread for the second beam 32.
    A third unitary beam 33 is shown in FIG. 7 on the basis of a third light source 23, one emission face of which is placed opposite an input face of a third optical element 13; the light passes through the optical element 13 to an exit diopter which can be convexly convex, and possibly in the shape of a portion of a sphere, so as to produce a desired spread for the third beam 33. In one embodiment , the third unitary beams 33 provide a route complement function, the third output beam resulting therefrom being mainly directed above the horizon line 36.
    The invention is not limited to the embodiments described but extends to any embodiment in accordance with its spirit.
