    [0001] The technical field of the invention is that of lighting modules for a motor vehicle.
    [0002] A motor vehicle is equipped with headlamps, or headlights, intended to illuminate the road in front of the vehicle, at night or in the case of reduced luminosity. These projectors can generally be used in two lighting modes: a first mode "high beam" and a second mode "low beam". The "high beam" mode provides strong illumination of the road far ahead of the vehicle. The "low beam" mode provides more limited illumination of the road, but still offers good visibility without dazzling other road users. These two lighting modes are complementary. The driver of the vehicle must manually change the mode according to the circumstances, at the risk of dazzle inadvertently another user of the road. In practice, changing the lighting mode manually can be unreliable and sometimes dangerous. In addition, the dipped beam mode provides visibility sometimes unsatisfactory for the driver of the vehicle. To improve the situation, projectors equipped with an adaptive lighting function (known in particular under the acronym AFS for "Adaptive Frontlighting System") have been proposed. Such an adaptive lighting function is intended to detect automatically, for example by the image processing acquired by an on-board camera, a user of the road likely to be dazzled by a lighting beam emitted in fire mode. by a projector, and to modify the outline of this light beam so as to create a shadow zone at the location where the detected user is located. The advantages of such an adaptive lighting function are multiple: comfort of use, better visibility compared to lighting in dipped beam mode, better reliability for the change of mode, risk of glare greatly reduced, driving safer . Document EP2280215 describes an example of a lighting system for a motor vehicle headlamp, with an adaptive lighting function. The system comprises four primary optical modules, in each of which three light sources are associated with three respective light guides, as well as four secondary optical projection elements, in this case lenses, respectively associated with the four primary optical modules. The light emitted by each light source enters the associated light guide and exits through an outlet end of the guide, of rectangular shape. The arrangement of the modules and their associated secondary optical element causes the light emitted by each optical guide output end to be projected by the secondary optical element so as to form a vertical light segment at the front of the vehicle. The light segments produced overlap partially in the horizontal direction. Then we play on the actuation of light sources that can be ignited independently of one another, selectively to obtain the desired lighting. The beam is thus divided into a plurality of light segments that can be turned on or off. The adaptive lighting beam that can be achieved only by electronic ignition control of light sources, and without mechanical movement of an additional cache piece, is known as a matrix beam. Moreover, in the field of lighting, car manufacturers may seek to replace a lens with a mirror to answer questions of style, color or cost. However, this generates a problem of lighting efficiency, that is to say that the optical flux at the output of the system is less important than the flux at the source, because the reflectivity of a mirror (85% for an aluminum coating) is generally worse than the transmission of a lens. In the same way, the imaging is generally less good because when one passes from a lens to a mirror, one reduces the number of optical surfaces from two to one, which leaves less variables for the correction of the optical aberrations . Moreover, in a mirror system, the shift in the optical axis causes the light sources to have larger aperture angles in order to maintain good efficiency, which generates more optical aberrations. It will be understood that the use of a reflector is a priori unfavorable for a matrix beam system, in which it is desired to produce different light segments having a well-controlled shape and sharpness and in which it is therefore necessary to seek to reduce optical aberrations. . The present invention is placed in this context and is intended to provide a mirror illumination module for light beams said matrix beam having good photometric performance and good imaging, and which easily integrates into a lighting device of a motor vehicle.
    [0003] For this purpose, the invention proposes a primary optical element for a motor vehicle lighting module, comprising at least one light input member having an input face of the light rays, and in which the input member is connected to a corrective part comprising an output face of the light rays, the light input member and the corrective part forming a one-piece structure. It can be observed that the input face of the input member thus forms an input face of the primary optical element and that the output face of the corrective part forms an output face of the primary optical element. . The corrective part is delimited by at least three surfaces, among which is an intake surface through which the light input member emerges in the corrective part via a junction zone, at least one intermediate surface and an exit surface. exit surface forming the exit face of the corrective portion and the intermediate surface forming a reflective surface arranged to reflect rays from the light input member to the convex surface. The junction zone may in particular be of rectangular shape. Thanks to the invention, light rays emitted from a light source disposed in the vicinity of the input face and penetrating into the primary optical element via this input face propagate in the primary optical element by internal reflection. total, especially on the intermediate surface. The input member is arranged to form a virtual secondary source from this light source at the junction area.
    [0004] The geometric aberrations of the rays issuing from this secondary source are partially corrected by the intermediate surface so that these rays, when they are projected on the road, for example by a secondary optical element, form a corrected image of the secondary source. According to one characteristic of the invention, the corrective part is arranged to correct the geometric aberrations of the light rays coming from the input member. In particular, the intermediate surface has a profile arranged to reflect the light rays by total internal reflection so as to treat geometric aberrations. According to one characteristic of the invention, the junction zone of the light input member is oriented towards the intermediate surface. This ensures that all the rays from the input member is directly targeted to the intermediate surface, without encountering obstacles in their path, so that it fully plays its role of total reflection surface.
    [0005] The exit surface of the corrective portion may have a convex shape. It may also have a generally spherical shape whose center is located outside the corrective part. For example, the corrective portion may have a truncated ball shape along two intersecting cutting surfaces to form a common edge disposed within the ball, and in this case the truncated portions of the ball form the surfaces of the ball. admission and intermediary. Advantageously, the corrective part forms another additional surface for geometric aberration processing by refraction. Preferably, the center of the spherical surface of the corrective portion is in the vicinity of the image of the center of the junction area of the light input member with the intake surface by the intermediate surface. By neighborhood is meant a distance of less than 5mm. The center of the ball is outside the corrective part. Thus the rays issuing from the light input member substantially at the center of the sphere enveloping the corrective part are normal to the exit face thereof and are therefore not deviated to the interface between the corrective part. and the surrounding air. The radii coming out of the light input member eccentrically are for their part slightly deflected to the output interface. The intermediate surface has a convex shape, especially towards the inside of the corrective part, and it can in this case have a polynomial profile. Its characteristic equation is of polynomial form, calculated so that each ray arrives with an angle of incidence sufficient to be totally reflected.
    [0006] For example, the surface equation can be Z =, -84.715 (1 ÷) 0) 2 14.211 (foo) 2 + 1324.046 (-00) 2 Lo) + 11.714 (1 ÷ 7.0) 3 + 2347.586 () 4 - 3535.841 (Ife H3) 2 (if) 70) 2 - 151.502 () 4 100 100 It may also be provided that the intermediate surface is flat. According to other features of the invention, taken alone or in combination, the intermediate surface and the junction zone are inclined with respect to each other in particular at an angle of approximately 45 °. And the respective refractive indices of the light input member and the corrective portion are substantially identical. By "substantially identical" is meant to denote refractive indices equal to one hundredth. Thus, at the exit of the light input member, the rays undergo no or almost no refraction. In a particular embodiment, the light input member and the corrective part are made of the same material, and in particular in the same polymer. By "same material" is meant that the light input member and the corrective part are made of materials at least derived from the same base polymer, for example PMMA. However, these materials may have different charges. According to a characteristic of the invention, the intake surface is flat at least at the junction zone. Alternatively, the inlet surface may be curved at least at the junction area. The light input member may be formed by a microlens. It may also, as will be described later, consist of a light guide forming the input member, one of the faces of the guide, upper or lower, having a cylindrical portion shape. It is thus a total internal reflection face of the guide. The light guide comprises at least one spreading face. A spreading face is understood to mean a face shaped so as to widen the cross section of the guide from its inlet face to the junction with the corrective part. The spreading face may for example be the face opposite to the face having a cylindrical portion shape. The primary optical element advantageously comprises a plurality, including four, of light guides each forming a light input member, the light guides being integral with the corrective portion at the inlet surface. In this case, it is notable that one of the end guides of the plurality of guides has a lateral spreading face, all the other guides having planar lateral faces. The guides can be juxtaposed to form a row. The invention furthermore relates to a light module of a motor vehicle, in which a primary optical element as described above is provided, and at least one light source associated with the light input member of the motor vehicle. primary optical element. The light source may be for example a light emitting diode, or a laser diode. According to various features of the invention, taken alone or in combination: a plurality of light sources each associated with the primary optical element is provided; in this case, the primary optical element may comprise a plurality of light input members, each light source being associated with one of the input members; alternatively, the primary optical element may comprise a single input member, each source being associated with this member; the primary optical element is arranged facing a secondary optical projection element, the junction zone of the element with the inlet surface being merged with a focal surface, plane or curve, object of the formed projection system by the primary and secondary optical elements; alternatively, the exit surface of the primary optical element may form an optical projection surface, in which case the light module is devoid of a secondary optical element distinct from the primary optical element. the secondary optical element is formed by a mirror. This mirror may have a conical aspherical profile, or alternatively, a parabolic profile. Advantageously, the mirror may be provided with ridges. It can also be provided that the secondary otic element is formed by a lens, or even one or more lens (s) and / or one or more mirror (s). It is noted that the module may have three geometric aberration processing surfaces of the light rays, two of which are carried by the primary optical element. The outlet face of the guides is disposed in the plane of the intake surface of the corrective part which coincides with an object focal plane of the projection system formed by the primary and secondary optical elements. The positioning of the "output plane" of the guides (this "exit plane" designating the surface, not necessarily plane, in which the outputs of the guides extend) in the object focal plane of the projection element makes it possible to create the infinite an image of the secondary light sources at the exit of the guides, thus producing luminous segments of corresponding forms. It can be provided that the three geometric aberration treatment surfaces succeeding each other for a light ray from the light guide to the output of the module are an internal total reflection surface carried by the primary optical element, a refraction surface also carried by the primary optical element, and a second reflection surface formed by the secondary optical element. The invention further relates to an automotive lighting system comprising at least one light module as evoked above, and a control module of the light source or sources associated with this light module.
    [0007] Preferably, the lighting system comprises a module for detecting an obstacle present on the road and not to dazzle. The ignition or extinction of a light source is thus a function of the detection of such an obstacle so for example to illuminate the entire road with the exception of said obstacle.
    [0008] The system may advantageously comprise a plurality of light modules according to the invention. It may be noted that, advantageously, the light module of the lighting system is arranged to produce a plurality of light strips, each strip being formed, for example, from one of the light sources of this light module. The set of light bands produced by the system form a light beam, each of which strips can be turned on or off, by turning on or off the light source producing said strip by the control module. Other characteristics and advantages of the invention will appear on reading the detailed description of an embodiment which follows and for the understanding of which reference will be made to the appended drawings in which: FIG. 1 is a perspective view elements of a lighting module, according to a first embodiment of the invention, namely primary and secondary optical elements and a plurality of light sources arranged opposite the primary optical element; Figure 2 is a side view of the elements of the module of Figure 1; and FIG. 3 is a sectional view of the primary optical element as illustrated in FIG. 1. In the following description, a longitudinal, vertical and transverse orientation will be adopted in a nonlimiting manner according to the orientation conventionally used. in the automobile and indicated by the trihedron L, V, T shown in FIG. 1. As illustrated in the figures, a light module according to the invention, intended to equip a motor vehicle headlamp, mainly comprises a plurality of primary light sources 1, a primary optical element 2 and a secondary optical projection element 4.
    [0009] The primary light sources are, in the particular example described here, light-emitting diodes. Light emitting diodes, however, could be replaced by other light sources, such as laser diodes. The secondary optical element 4 is here a convergent mirror, made of a material that has a reflective coating. It is arranged and configured to project to infinity the images formed at the focal plane 5, shown in dashed lines in FIG. 2, of the projection system that together form the primary optical element and the secondary optical element. The primary optical element 2 comprises a corrective part 6 and a light input member 8 associated with the light sources 1.
    [0010] In the embodiment that will be explicitly described, the input member consists of a number N of light guides 8 respectively associated with the N primary light sources 1. The N light guides are integral with the part corrector so that they form a monoblock structure, that is to say that these parts are not separable without destruction of one of them. The use of light guides allows greater tolerance in the positioning of light sources, which can be mounted on a common support, not shown here. It is understood that the light guides 8 and the corrective part 6 are made of the same material or are derived from the same polymer. As an illustrative example, the guides may be made of PMMA-HT (Polymethyl Methacrylate High Temperature) of refractive index equal to 1.490 and resistant to high temperatures, and the corrective part PMMA-8N refractive index equal to 1.491 and less expensive. The refractive indices are substantially the same so that, as will be described hereinafter, the light passing from the guide to the corrective part is substantially not deviated. In order to allow the path of the light rays, the material constituting the guides and the corrective part is transparent. This is a material for an optical lens, such as an organic material or possibly glass. In the particular example described here, the number N of guides is equal to four. Of course, this number could be greater or less than four. However, it is preferably strictly greater than one, in particular for applying the module of the invention to an adaptive lighting system. The guides are here juxtaposed one after the other to form a single horizontal row. Alternatively, the guides could be juxtaposed two by two.
    [0011] Each light guide has a substantially prismatic shape, a light-input face 10 and an opposite exit face 12, opening on the corrective part 6, form the rectangular bases. Each guide further comprises two lateral faces 14 which extend longitudinally and vertically, oriented towards the secondary optical element, and two transverse faces which extend vertically and transversely, substantially parallel to the secondary optical element, and among which a anterior transverse face 16 is further away from the secondary optical element than a posterior transverse face 18. The input face 10 of each guide is here planar and extends opposite a primary light source 1, the distance between an output plane of the light source and the input face of the associated guide being advantageously between 0.1 millimeters and 1 millimeter. The light emitted by the primary sources is intended to propagate inside the guide, from the input face to the exit face, by successive total reflections on the internal walls of the transverse and lateral faces, to open into the corrective part of the primary optical element. The outlet faces of the guides, here rectangular, then constitute secondary light sources intended to produce respective light beams at the module outlet, after treatment of the light by the corrective part. The faces may take a flat or curved shape, of any shape, and they are advantageously formed to produce a desired shape of light beam at the output of the light module. By way of example, the lateral faces, and the anterior and posterior transverse faces, may be given flat or curved spreading shapes, shaped so as to widen the cross section of the corresponding light guide, from its face. entrance to its exit face. The anterior transverse face 16 takes the form of a right face while the posterior transverse face 18, as can be seen in FIG. 3, takes the form of a curved face. The inclination of the transverse faces relative to each other makes it possible to size the size of the exit face and therefore of the image projected by the secondary light source. The corrective part 6 is formed by a ball truncated by two cutting surfaces. These cutting surfaces intersect at a common edge 20 which extends within the ball such that the center of the ball is outside the corrective portion. The two surfaces defined by these cutting surfaces, and which extend from the common edge to the contour of the ball, are inclined relative to each other by an angle of about 45 °.
    [0012] In this way, the corrective part has the shape of a ball portion defined by three surfaces that will be called, with reference to their function as will be explained in detail later, an intake surface 22, a intermediate surface 24 and an outlet surface 26.
    [0013] A first cutting surface of the ball generates the substantially planar intake surface which forms a receiving face for the light guides reported and aligned on this intake surface. The intake surface has the exit faces of the guides. The distance separating the primary and secondary optical elements is strictly greater than zero and adapted so that the junction zone of the outlet faces of the guides and of the admission surface coincides with the object focal plane of the projection system formed by the optical element primary and the secondary optical element. Thanks to this, the module according to the invention, and its two primary and secondary optical elements, is adapted to create an infinite image of the secondary light sources formed at the output ends of the guides. The second cutting surface traces the contour of the intermediate surface which, as can be seen in FIG. 3, is curved towards the inside of the corrective part. Indeed, in order to obtain a total internal reflection of the rays on this intermediate surface, it is expected to bend this surface according to a polynomial equation, the parameters of which will depend, for example, on the size of the corrective part, the angle between the intake surface and the intermediate surface.
    [0014] The equation could be: Z =, -84.715 (1 ÷) 0) 2 14.211 (foo) 2 + 1324.046 (-00) 2 Lo) + 11.714 (1 ÷ 7.0) 3 + 2347.586 () 4 - 3535.841 (Ife H3) 2 (if) 70) 2 - 151.502 (13i) 70) 4 100 The intermediate surface is oriented so that the exit faces of the light guides are all turned towards this surface so that the entire light rays come into contact with the total reflection intermediate surface. The exit surface of the corrective portion is formed by the outer wall of the ball and is facing the mirror forming the secondary optical element.
    [0015] The different parts of the primary optical element will now be functionally described, based on the path of the rays illustrated in FIG.
    [0016] In operation, the light rays emitted by a light source 1 penetrate, at least partially, into the associated guide 8 by its inlet face 10. These rays are channeled in the guide by successive total reflections and propagate to the interior of the guide from its inlet face to its exit face, possibly by successive reflections on the transverse faces (visible in the sectional view of Figure 3) or on the lateral faces. At the interface between the outlet face of the guide and the inlet surface of the corrective part 6, the rays issuing from the guide penetrate into the corrective part without being deflected. All of the spokes are then accurately directed to the internal reflection surface to be reflected toward the exit surface.
    [0017] The intake surface is shaped so that the portion of the "exit plane" in which the outlets of the guides extend is oriented towards the intermediate surface so that the rays issuing from the guide go in the direction of this surface. Moreover, the rectangular shape of the exit face of the guide, and its dimensions, prevents the rays coming out of the guide from departing in a direction other than that leading to the polynomial reflection surface and that they thus escape the intermediate stage of internal reflection between the admission and the exit of the rays in the corrective part. It is ensured in the construction of the module that the end of the rear transverse face 18 at the outlet face of the guide closes towards the corresponding end of the front transverse face 16 so that the rays coming from the diode and following the end of the posterior transverse face without being deflected in the guide propagate well towards the internal reflection surface. Controlling the scattering of the rays to target them towards the internal reflection surface is facilitated by the absence of refraction between the guides and the corrective part. The rays are integrally reflected by the polynomial shape of the internal reflection surface in the direction of the exit surface. The spokes then move in straight lines to the exit surface of the corrective portion. Since the ball is centered on a virtual point corresponding to the image point of a secondary source obtained by symmetry with respect to the polynomial surface, the rays come into contact with the output surface of the primary optical element substantially normally relative to to this spherical wall, and they are integrally refracted, and without alteration of the image they form, towards the secondary projection element 4.
    [0018] The rays are reflected by the mirror forming this secondary projection element to form at infinity images corresponding to those of the secondary light source, that is to say beams of parallel rays forming luminous segments of generally rectangular shape.
    [0019] It will be understood that the corrective part carries two geometric aberration reduction surfaces for the light rays, namely the intermediate surface which acts as a total internal reflection surface and the exit surface which acts as a refraction surface. The foregoing description clearly explains how the invention makes it possible to achieve the objectives that it has set itself and in particular to propose a light module that facilitates the implementation of an effective adaptive lighting system. Other variants may be implemented without departing from the context of the invention, as the embodiment of the light input member by a plurality of guides, made or not in one-piece form, or a plurality of microlenses.
    [0020] It is observed that in the lighting module according to the invention, the light rays successively undergo a total reflection, a refraction and a second reflection, it being understood that they also know an initial refraction at the entrance to the guides, and total reflections on the walls of the guides. The role of the corrective part 6, in cooperation with the light input member, is twofold. On the one hand, it improves the optical efficiency of the light module. The entry of the guides has the effect of reducing the opening of the light rays emitted by the primary light sources, the rays penetrating the guides being folded by the laws of refraction. It is known that a light ray penetrating into an optical guide with an opening with respect to the normal to the entrance surface of this guide is folded towards the longitudinal axis of the guide by the laws of refraction at an arcsine angle ( l / n * sin (a)). In this way, it is possible to calibrate the shape and dimensions of a secondary light source at the exit face of each of the light guides. In addition, at the interface between each light guide and the corrective part 6, the light rays are not deflected due to the connection between the guides and the corrective part 6. Thanks to this, the reduced opening of the rays is preserved, and we can target the path of the rays in the direction of the internal reflection surface. The corrective part advantageously offers an intermediate surface of total reflection between the inlet and the outlet of the ball by refraction, to improve the treatment of the geometric aberrations of the light rays. Finally, these light rays issuing from the corrective part 6 by the exit surface are not deviated or little by the spherical dome shape of the exit surface, because it is centered on the image of the secondary source obtained. by symmetry with respect to the internal reflection surface. The assembly formed by the diodes and the light guides generates, at the output of the guides, rectangular light segments of illumination which are then imaged at infinity with two reflecting surfaces and a surface of refraction. The two reflective surfaces allow the correct correction of optical aberrations so that brightly defined segments of sharpness and shape can be formed in order to maximize visibility on the night road and comfort without dazzling other users. The fact that one of the two reflecting surfaces is a dioptric surface working in total reflection makes it possible to limit the reflection losses on this surface compared to what they would be on a mirror. In this system, therefore, two reflective surfaces are kept at a low level of losses, similar to what one would have if the system were composed of only one mirror. Advantageously, the module according to the invention also comprises a refraction surface formed by the output surface of the primary optical element, which further contributes to the correction of field aberrations. Thus, with only two optical elements and in a relatively compact system, there are three optical surfaces for imaging light segments while maintaining a relatively low level of losses for a mirror system, preferred to a lens system for reasons previously mentioned, including the cost. Thus, the light module of the invention has excellent optical efficiency. The luminous flux emitted by the sources undergo little loss and are recovered largely at the output of the module to create light beams capable of forming light segments.
    [0021] In addition, the light module can produce light segments whose shapes are perfectly controlled. In particular, the vertical boundaries of the light segments have a shape and clarity well controlled.
