    TECHNICAL FIELD OF THE INVENTION
    The invention relates to an optical lighting module for a motor vehicle comprising a primary optical element comprising:
    a first rear portion comprising a plurality of light guides with a longitudinal main axis arranged in at least one transverse row, and each comprising a front end face for the exit of a secondary light beam;
    - A front portion which has a common front face for the exit of the secondary light beams.
    TECHNICAL BACKGROUND OF THE INVENTION
    Optical lighting modules of this type are already known. They are capable of emitting longitudinally forward a final light beam called multibeam or even pixel beam. The final light beam projects an image of a matrix of elementary light sources forward. By selectively switching on or off each of the basic sources, it is possible to create a final light beam specifically illuminating certain areas of the road in front of the vehicle, while leaving other areas in the dark.
    Such an optical lighting module is used in particular to perform an adaptive lighting function also called ADB, acronym for the English expression Adaptive Driving Beam. Such an ADB function is intended to automatically detect a road user liable to be dazzled by a lighting beam emitted in high beam mode by a headlamp, and to modify the outline of this lighting beam so creating a gray area at the location of the detected user while continuing to illuminate the long-range road on either side of the user. The advantages of the ADB function are multiple: user comfort, better visibility compared to lighting in low beam mode, risk of glare greatly reduced, safer driving ...
    Such an optical module generally comprises a matrix of light sources, generally formed by light-emitting diodes (LEDs), a primary optical element comprising a plurality of light guides and projection optics. The light emitting diodes are arranged on a flat printed circuit board which extends in a plane orthogonal to the direction of projection of the final light beam. The light guides of the primary optical element extend generally longitudinally from an entrance face of the light to an exit face of the light. The light guides are intended to conform the rays emitted by the light-emitting diodes into a narrower light brush, the exit face of each light guide forming a pixel. The exit faces of the light guides form a matrix of elementary pixels imaged by the projection optics. Each pixel is capable of being selectively lit by activation or deactivation of each light source.
    Such a primary optical element comprises a first row of first light guides intended to form elementary pixels of rectangular shape which are intended to illuminate above a cut line.
    Such a primary optical element also comprises a second row of second light guides intended to form elementary pixels of square shape which are intended to illuminate below a cut-off line.
    The square pixel images thus illuminate the road near the vehicle, while the rectangular pixel images illuminate the road at a greater distance.
    The images of rectangular pixels are likely to dazzle road users located a short distance from the vehicle. Adaptive lighting consists in detecting such road users and turning off the light sources forming the pixels capable of dazzling said users while keeping the other light sources on to guarantee good visibility to the driver of the vehicle.
    In order for the optical light module to produce a final light beam which is comfortable for the driver, the images of the rectangular pixels vertically overlap the images of the square pixels. It has been found that driver comfort is improved when the images of the rectangular pixels extend more than 5 ° vertically.
    However, currently, a single light guide does not make it possible to obtain a rectangular pixel as vertically extended while remaining relatively narrow transversely.
    In addition, it has also been found that better visual comfort is obtained when the square pixels have a blurred lower edge.
    In addition, a visually comfortable light beam must also illuminate the side of the road. However, even by modifying the shape of the light guides arranged at the transverse end of the primary optical element, the pixels produced by the transverse end light guides are not wide enough to sufficiently illuminate the aisle of the road.
    BRIEF SUMMARY OF THE INVENTION
    The object of the invention is to present an optical lighting module making it possible to produce a pixel light beam, or pixel beam capable of comfortably illuminating the road.
    The invention thus relates to an optical lighting module of the type described above, characterized in that the front face of the front portion is shaped to spread the secondary light beams at least in a vertical direction.
    According to other characteristics of the invention:
    - The exit face of the front portion of the primary optical element has at least one transverse strip with a curved vertical end around a transverse axis for spreading the secondary light beams vertically emitted by an associated row of light guides;
    the optical module comprises at least two parallel transverse rows of light guides, the exit face of the front portion of the primary optical element having two transverse bands of vertical end each curved around a transverse axis to spread the beams secondary luminaires vertically emitted by a row of associated light guides;
    - The exit face of the front portion comprises a central strip which extends vertically between the two vertical end strips and which has, in longitudinal vertical section, a vertical rectilinear shape;
    - at least one transverse end section of the exit face of the front portion has a curvature around a vertical axis to spread the secondary light beam emitted by the corresponding end light guide of each of the rows in a direction transverse;
    - the two sections of transverse ends of the exit face of the front portion each have a curvature around a vertical axis to spread the secondary light beam emitted by the corresponding end light guides of each of the rows in a direction transverse;
    - A central section of the outlet face of the front portion extending between the two transverse end sections has a semi-cylindrical shape;
    - The central section extends opposite the light guides of each row with the exception of the two end light guides;
    - each light-emitting diode is associated with a light guide;
    - The optical module is capable of emitting a light beam performing an adaptive lighting function.
    The invention also relates to a motor vehicle lighting device comprising the module produced according to the teachings of the invention.
    The lighting device further comprises a low beam module.

    In the following description, elements having an identical structure and / or analogous functions will be designated by the same references.
    FIG. 1 shows an optical module 10 for lighting a motor vehicle which is intended to emit a final light beam longitudinally towards the front. This is an adaptive light beam which is composed of a plurality of overlapping elementary beams. Such an optical lighting module 10 is in particular capable of fulfilling an adaptive high beam function, also known under the name ADB for Adaptive Driving Beam, or it is also capable of fulfilling a function of directional lighting, also known as DBL for Dynamic Bending Light.
    The optical module 10 is intended to equip a front lighting device for a motor vehicle. The front lighting device also comprises a second optical module intended to emit a single crossing light beam with cut-off.
    The optical lighting module 10 mainly comprises means 12 for emitting light and a projection optic 14 which is arranged longitudinally in front of and at a distance from the emission means 12. The projection optic 14 has a longitudinal optical axis A
    As shown in FIG. 2, the light emitting means 12 here comprise a matrix 16 of primary elementary light sources 18. These are light-emitting diodes 18. The matrix 16 is equipped with at least two transverse rows of seventeen light-emitting diodes 18, here two rows. The optical axis A passes substantially in the middle of the matrix 16 in the transverse direction. All the light-emitting diodes 18 of the matrix have illuminating surfaces of identical dimensions. These are square-shaped lighting surfaces.
    The matrix 16 extends in a plane orthogonal to the longitudinal direction L. More particularly, the light-emitting diodes 18 are here carried by the front face of a printed circuit card 20.
    These light-emitting diodes 18 are capable of emitting heat during their operation. A heat sink 22 comprising cooling fins is therefore attached to the back of the printed circuit board 20 to remove the heat.
    The light-emitting diodes 18 emit light rays in a very open cone of light. In the example shown in Figure 5, the opening angle is 180 °. A primary optical element 24 is arranged longitudinally in front of the matrix 16 of light-emitting diodes 18 to modify the distribution of the emitted light rays.
    As shown in FIG. 3, the primary optical element 24 here comprises a first rear portion 24A which is formed of a plurality of light guides 26A, 26B. Each light guide 26A, 26B extends along a main longitudinal axis from an entry face 28A, 28B, to an end face 30A, 30B before the exit of the light rays, in particular visible in FIGS. 4 and 5 Each light guide 26A, 26B is designed to guide the rays entering through the entry face 28A, 28B to the exit face 30A, 30B. Each output face 30A, 30B forms a pixel capable of being selectively lit by individual control of each light-emitting diode 18.
    The rear portion 24A comprises a matrix comprising at least as many light guides 26A, 26B as the matrix 16 comprises light-emitting diodes 18. Each light-emitting diode 18 is associated with a light guide 26A, 26B. Thus, the rear portion 24A comprises at least two rows of seventeen light guides 26A, 26B.
    The entry faces 28A, 28B of the light guides 26A, 26B are arranged in a common plane which is parallel to the plane of the printed circuit board 20. When the primary optical element 24 is arranged in the optical module 10, each input face 28A, 28B is thus positioned longitudinally opposite and near an associated light-emitting diode 18, as illustrated in FIG. Figure 4, so that most of the light rays emitted by each light emitting diode 18 enters the guide 26A, 26B of associated light.
    As can be seen in FIG. 3, each light guide 26A, 26B is capable of having a cross section adapted to produce a secondary elementary light beam emerging from the shape desired for the function of the optical lighting module 10. Each secondary elementary light beam has a more restricted opening angle than that of the light source 18.
    As shown in the figures, the primary optical element 24 has two transverse rows of light guides. The light guides of the first lower row will be designated by the reference 26A while the light guides of the second upper row will be designated by the reference 26B.
    The light guides 26A of the first type, hereinafter called the first light guides 26A, occupy the lower row. They are intended to form elongated pixels in height. More particularly, the elongated pixels have a generally rectangular shape whose length extends vertically. To this end, the exit face 30A of the first light guides 26A has a corresponding rectangular shape.
    The second type light guides 26B, hereinafter called second light guides 26B, occupy the upper row. They are intended to form short pixels in height relative to the elongated pixels. More particularly, the short pixels have a generally square shape. To this end, the outlet face 30B of the second light guides 26B has a corresponding square shape.
    For each of the light guides 26A, 26B, the outlet face 30A, 30B has an outline similar in shape to that of the inlet face 28A, 28B. Thus, the face 28A of entry of the first light guides 26A has a contour of rectangular shape. Likewise, the input face 28B of the second light guides 26B has a square-shaped contour.
    As explained in the introduction, the image of a rectangular pixel is intended to vertically overlap the image of a square pixel. To this end, each first light guide 26A is associated with a second parallel light guide 26B which is arranged near and to the right of the upper edge of said first associated light guide 26A.
    The exit faces 30A, 30B of the light guides 26A, 26B are arranged in a common emission plane P which is parallel to the plane of the printed circuit board 20, as shown in FIG. 4. In this way, the guides 26A, 26B of light all have an identical length.
    The exit faces 30A, 30B of the light guides 26A, 26B thus form a matrix, here a first row of seventeen exit faces 30A of the first light guides 26A and a second row of seventeen exit faces 30B of second light guides 26B. Each of the exit faces 30A, 30B is capable of emitting a secondary elementary beam in a main longitudinal direction of projection from the common emission plane P orthogonal to the longitudinal direction L. The exit faces 30A, 30B are arranged in the immediate vicinity from each other, for example with a deviation of 0.1 mm.
    The primary optical element 24 also includes a portion 24B before shaping the secondary elementary light beams emitted by the elementary light sources.
    The front portion 24B has a common front end face 32 for the exit of the light rays from the primary optical element.
    This front portion 24B is here produced integrally with the light guides 26A, 26B so that the primary optical element 24 is produced in one block.
    The primary optical element 24 is for example made of silicone, polycarbonate, polymethylmethacrylate (PMMA) or any other material suitable for the production of light guides 26A, 26B.
    Alternatively, the primary optical element 24 made according to the teachings of the invention is made of silicone.
    The front face 32 of exit from the front portion 24B is shaped to spread the secondary elementary light beams vertically and / or horizontally.
    The front face 32 has a generally rectangular contour whose length extends transversely, parallel to the rows of light guides 26A, 26B, and whose width extends vertically. The front face 32 is thus delimited vertically by a lower transverse edge 36A and by an upper transverse edge 36B. The front face 32 can also be delimited transversely by two vertical edges 37.
    Thereafter, and as illustrated in FIG. 5, a lower area 32A of the front face 32 will be distinguished which is intended to receive the secondary light beams emitted by the light guides 26A of the lower row, and a area 32B upper of the front face 32 which is intended to receive the secondary light beams emitted by the light guides 26B of the upper row.
    According to a first aspect of the invention, the front face 32 of the front portion 24B is shaped to spread the secondary light beams at least in a vertical direction.
    For this purpose, the exit face 32 of the front portion 24B of the primary optical element has at least one transverse strip 38A, 38B of free vertical end which is curved around a transverse axis to spread the secondary light beams vertically emitted by a row of light guides 26A, 26B associated with this end strip 38A, 38B. Said transverse strip 38A, 38B at the end of the outlet face 32 thus has a convex shape.
    In the example shown in FIG. 5, the primary optical element 24 comprises two parallel transverse rows of light guides 26A, 26B. To allow the vertical spreading of the light beams emitted by the light guides 26A, 26B of each of these two rows, two transverse end bands delimiting vertically the exit face 32 of the front portion 24B of the primary optical element are each curved around a transverse axis to spread the secondary light beams vertically emitted by each row of guides 26A, 26B of associated light.
    More particularly, the lower zone 32A has a strip 38A of lower end bordering the lower edge 36A of the front face 32. This strip 38A of lower end has a convex progressive curvature which is shaped to spread the light rays vertically so as to form a light beam which extends over more than 5 ° vertically. To this end, in vertical longitudinal section, the curvature of the strip 38A of the lower end has a tangent forming an angle generally less than 45 ° over the majority of the curvature. Thus, the light rays are slightly deflected downwards by refraction passing through the strip 38A of the lower end. However, the secondary light beam emitted by each of the associated light guides 26A and exiting through the face 32 has a relatively clear lower limit.
    Of course, it will be understood that the invention is not limited to this particular curvature, and that the curvature can be adapted as a function of the desired spread for the light rays.
    The upper area 32B has an upper end band 38B bordering the upper edge 36B of the front face 32. This upper end strip 38B has a convex curvature whose radius of curvature is more marked than that of the lower end strip 38A so that the secondary light beam forms a pixel having a fuzzy upper limit. For this purpose, in vertical longitudinal section, the curvature of the upper end band 38B has a tangent forming an angle generally greater than 45 ° over the majority of the curvature. Thus, the light rays from the top of the secondary light beam are deflected upwards by a very large angle by refraction passing through the strip 38B of the upper end. Thus, the secondary light beam emitted by each of the associated light guides 26B and exiting through the face 32 has a fuzzy upper limit.
    In order for the overlapping portions of secondary light beams to have a clear limit, the exit face 32 of the front portion 24B comprises a central strip 40 which extends vertically between the strips 38A, 38B of upper and lower ends. This central strip 40 has, in longitudinal vertical section, a rectilinear shape.
    As a variant, the height of the central strip can be adapted.
    According to another variant of the invention, the outlet face does not have a central strip. Thus, the two curved strips are connected directly to each other without the interposition of a central strip.
    In addition, to allow the secondary light beam emitted by the end light guide 26A, 26B which is situated on the side of the road for each row to be spread transversely, at least one vertical section 42 of transverse end of the exit face 32 of the front portion 24B has a curvature around a vertical axis for spreading the secondary light beam emitted by the guide 26A, 26B of corresponding end light of each of the rows in a transverse direction. The vertical section 42 has for this purpose a convex shape in longitudinal cross section.
    In the example shown in the figures, the same primary optical element 24 is advantageously intended to equip vehicles independently of the mounting side, to the left or to the right.
    To allow the same primary optical element 24 to thus be adapted to the two mounting sides, the two vertical sections 42 of transverse ends of the exit face 32 of the front portion 24B each have a curvature around a vertical axis to spread out the secondary light beam emitted by the corresponding end light guide from each of the rows in an opposite transverse direction.
    Alternatively, the outlet face has only one curved end section, the other end section being omitted. Referring to Figure 6, one end 42 of the optical module is then removed. The optical module thus has an asymmetrical outlet face with respect to a vertical longitudinal median plane. In this case, a different primary optical module is arranged on each side of the vehicle.
    The vertical end bands 38A, 38B overlap the sections 42 of transverse ends. Thus, the two end sections 42 simultaneously have curvatures both around a transverse axis and around a vertical axis. In other words, the sections 42 of transverse ends have a spheroidal shape. In this way the secondary light beams emitted by the end light guides 26A, 26B are spread vertically and transversely, so as to form a light distribution in the form of a veil.
    On the contrary, the secondary light beams emitted by the other light guides 26A, 26B are intended to be spread only in a vertical direction by the exit face 32. A central section 44 of the outlet face extends opposite the light guides 26A, 26B of each row with the exception of the two end light guides. In this regard, the central section 44 of the outlet face 32 of the front portion 24B, extending between the two sections 42 of transverse end, has a semi-cylindrical shape. By semi-cylindrical, it will be understood that the central section 44 of the front outlet face 32 is generated by displacement of a transverse straight line along an open curve formed by the vertical profile of the three transverse bands 38A, 38B, 40, as shown in Figure 5. The outlet face 32 thus has a smooth appearance. In a variant not shown, the outlet face can also be grained in parts.
    Furthermore, the projection optics 14 is arranged longitudinally at a distance in front of the emission plane P. The projection optic 14 is capable of projecting an image of the output faces 30A, 30B towards infinity to form the final light beam. In projection on a vertical transverse screen (not shown) located at a great distance, for example at 25 m, each face 30A, 30B of illuminated output makes it possible to illuminate an area of the screen. The areas overlap slightly to provide even lighting. Each diode 18 is individually controlled so as to be able to selectively illuminate each of the areas of the screen.
    The projection optic 14 is here produced in a single block.
    In known manner, the projection optic 14 comprises an object focal surface S extends generally orthogonally to the optical axis A which it intersects at the object focal point.
    In order for the final beam obtained to have the desired light characteristics for its use, it is necessary for the output faces 30A, 30B to be imaged in a substantially clear manner. To this end, each elementary light source 30 is either located on the focal surface object of the projection optics 14.
    Theoretically, the projection optics 14 is supposed to have a plane object focal surface and perfectly orthogonal to the optical axis A. However, in reality, it is known that the projection optics 14 has an object focal surface having a concave spherical curvature defect. Such a defect is called a Petzval field aberration.
    To allow the projection optics 14 to be correctly focused on the elementary light sources 30, a secondary optical element for field correction is interposed between the emission plane P and the projection optics 14. This optical field correction element 34 is specifically designed to correct the aberration of field curvature of the projection optics 14. The optical element for field correction is formed by at least one field correction lens also known by its English name of field flattener lens. In the example shown in the figures, the optical element for field correction comprises a single field correction lens which will therefore be referenced 34.
    It will be noted that the entry faces 28A, 28B of the two light guides 26A, 26B situated at the lateral ends are not arranged in the same vertical transverse plane. The faces 28A, 28B are for example arranged in a fan shape around the light-emitting diodes. This makes it possible to participate in the spreading of the beam in the transverse direction.
