Definitions

  • the invention relates to the field of lighting and/or signaling, in particular for motor vehicles. More particularly, the invention relates to a lighting and/or signaling module for a motor vehicle.
  • a light module incorporates a movable mechanical element, designed to participate in the formation of a particular beam at the request of the driver or the associated control system.
  • the document FROM 10 2006 042 749 discloses a lighting device for a vehicle headlight comprising an LED light source, an elliptical-type reflector in a half-space with two foci.
  • the LED source is placed at the first focus of the reflector in proximity to the latter.
  • the light emitted by the LED source is reflected by the reflector towards its second focus where a reflective surface called a folding surface is positioned.
  • This reflective surface has an edge on the reflector side and an edge on the side opposite the reflector. These edges are called “cut-off edges”.
  • a portion of the light beam reflected by the reflector meets the surface reflective and is reflected in accordance with its angle of incidence on the surface. Another part of the light beam passes beyond the cut-off edge(s) and is not deflected by the reflective surface. The cut-off edge thus defines a boundary between the reflected and therefore deflected part of the beam and the unreflected part.
  • a lens is positioned behind the reflective surface so that its focus corresponds to that of the elliptical reflector.
  • the reflective surface with its cut-off edge(s) is called a bending member because it deflects or "bends" part of the beam in order to form a cut-off at the level of the beam emitted by the lens.
  • the bending member is movable along an axis parallel to the optical axis of the reflector. This mobility makes it possible to ensure the "high beam” or “high beam” function and the "low beam” or “low beam” function. It is understandable that projectors of this type involve internal mechanics in the module which require great precision and which lead to a significant manufacturing cost.
  • ADB Adaptive Driving Beam in English
  • Selective beam Such an ADB function is intended to automatically detect a road user likely to be dazzled by a lighting beam emitted in main beam mode by a headlight, and to modify the contour of this lighting beam so as to create a shadow zone at the location where the detected user is located.
  • the advantages of the ADB function are multiple: ease of use, better visibility compared to lighting in dipped beam mode, better reliability for changing mode, greatly reduced risk of dazzling, safer driving.
  • the invention falls within this dual context of the presence of a "selective beam” function on the one hand, and a complementarity of "low beam” and “high beam” modes on the other hand, the invention having the objective of proposing a motor vehicle headlight whose lighting and/or signaling systems are at least as efficient as before, with improved compactness and lower cost.
  • the invention relates to a light module comprising first means arranged to produce a cut-off beam and second means arranged to produce at least two selectively activatable light segments, the light segments forming a beam complementary to the cut-off beam, when they are activated simultaneously.
  • the first and second means are arranged so as to arrange the shape of the beams at the output of the module.
  • the first means may be arranged so that the cut-off of the cut-off beam is generally horizontal, and the second means may be arranged so that each light segment has at least one vertical edge. It is particularly advantageous for the module to be arranged so that the light segments are superimposed on the generally horizontal cut-off of the cut-off beam, or else that they partially cover this cut-off.
  • the complementary means may comprise optical guides associated respectively with one of the second light sources, each optical guide having an input face and an output face so as to guide the light emitted by the associated second light source from the input face to the output face: for example, each light source may be formed by one or more semiconductor emissive chips, this or these chips being arranged opposite the input face of the associated optical guide; each optical guide may be arranged to form an image of the associated second light source at the output face of this guide, this output face being arranged at the focal zone of the projection device; the output face of each optical guide may be arranged to be in contact with the cover, the contact edge between each output face and the cover being in the focal zone; each optical guide may comprise a lower face and an upper face which extend between the ends of the input face and the output face, the lower face being turned away from the cover while the upper face is turned towards the cover, said lower face being a reflection face, for example having a substantially elliptical shape of which a first focus coincides with the location of the second light source and
  • the optical guides are arranged so that their respective downstream portion, carrying the output face, are joined against each other and their respective upstream portion, carrying the input face, are spaced transversely from each other.
  • the optical guides may be arranged in series in a fan-shaped arrangement.
  • each of the optical guides can be made individually and the guides are mounted relative to each other, in particular by gluing at the level of their downstream portion.
  • the downstream portions of two adjacent optical guides join upstream of the focal zone, to form a common area of overlap of the images formed by each guide.
  • the common area of the guides extends from a junction area upstream of the focal zone to the output face, at the level of the focal zone.
  • the optical guides can be made of a material allowing the propagation of light rays by internal reflection from the entry face to the exit face, for example polycarbonate (PC) or polymethyl methacrylate (PMMA) or silicone or glass.
  • PC polycarbonate
  • PMMA polymethyl methacrylate
  • the light module advantageously comprises first means arranged to produce a cut-off beam and second means arranged to produce at least two selectively activatable light segments; the first and second light sources corresponding to the first and second means can be arranged on a common support which extends between the two sub-modules; this common support then consists of a means for thermally cooling the light sources, the first and second light sources being arranged on either side of the common support; the first and second light sources are respectively associated with a printed circuit board, the common support carrying the printed circuit boards; the first and second light sources are mounted directly on the thermal cooling means: by "directly mounted", it is meant that the light sources are mounted without the intermediary of a printed circuit.
  • the invention also relates to a lighting system comprising at least one module as just described and control means for switching on, switching off or modifying the light power emitted by the first means and the second means of the light module.
  • control means can control the first and second means of the module.
  • a lighting system of this type can advantageously be provided with at least two modules, one of the modules being arranged in a left projector, the other module being arranged in a right projector; the modules are arranged relative to each other in such a way that at least one segment produced by one of the modules covers at least one segment produced by the other of the modules.
  • a light module for lighting and/or signaling a motor vehicle comprises, according to the invention, first means 2 arranged to produce a cut-off beam, an optical projection device 4 arranged on the path of this beam, at the output of the module, as well as second means 6 arranged to produce a beam complementary to the cut-off beam, when the first means and the second means are activated simultaneously.
  • FIG. 7 An example of a projection device is illustrated in the Figure 7 .
  • This is a lens 8 arranged axially upstream of the first and second means. It is understood that the projection device may have other forms known elsewhere, and for example be made up of one or more lenses and/or one or more reflectors.
  • the projection device has a focal zone, in particular a focal plane P represented by dotted lines in some of the figures and the position of the different elements of the projection device is precisely determined to obtain reliable positioning of this focal plane.
  • the first means and the second means are, in the orientation of the module illustrated in the figures, arranged one above the other, respectively forming a first sub-module 10 and a second sub-module 12 arranged in the same housing of the module, and each comprising at least one light source.
  • the module also comprises a common support 14 for the light sources corresponding to the first and second means, the common support extending between the two sub-modules.
  • the common support advantageously forms a means of thermal cooling of the light sources arranged on either side of this common support.
  • the first sub-module comprises a light source 16, a reflector 18 which is capable of deflecting rays emitted by the source towards the projection device. of light, as well as a cover 20, in particular reflective, to form a means of cutting off the beam of rays emitted by the light source.
  • the light source 16 consists of a semiconductor source, for example a light-emitting diode fixed on a printed circuit board.
  • the printed circuit board is fixed on the common support 14 separating the two sub-modules.
  • the reflector 18 is of the elliptical type. It comprises two foci, an optical axis and a substantially elliptical internal reflecting surface 22.
  • the light source 16 emits the majority of its light energy towards the internal reflecting face and it is arranged in the vicinity of the first focus of the reflector 18.
  • the entire first sub-module 10 is arranged so that the second focus is included in the focal plane P of the optical projection device 4, it being understood that it could be, without departing from the context of the invention, substantially in the vicinity of this focal plane.
  • the cover 20 is located between the reflector 18 and the optical projection device 4. It consists of a plate which extends parallel to the junction plane of the two sub-modules, here substantially horizontally.
  • the cover comprises a central reflection zone 24, as well as means for fixing to the module which are arranged laterally at each of the ends 26 of the plate.
  • the central reflection zone has a reflective upper face 28, a lower face and two longitudinal end edges among which the front edge, facing the projection device, forms a cut-off edge 30 arranged in the vicinity of the second focus of the reflector. The cover thus creates a horizontal cut-off of the beam and the concentration of the rays under this cut-off for the production of the beam corresponding to the "low beam” mode.
  • the second sub-module 12 is arranged to produce a second beam 13 complementary to the first beam 11 produced by the first sub-module 10, as illustrated in the figure 8 .
  • This complementary beam consists here of a selective beam allowing the realization of a non-dazzling main beam function.
  • a complementary beam is understood to mean a beam which forms with the beam produced by the first sub-module a coherent beam when the two sub-modules are controlled to simultaneously produce the emission of the light beam specific to them.
  • the beam emitted by the second sub-module is selective, that is to say that the beam is divided into several portions 34, which can be switched on or off selectively according to the control instructions of the light sources of the second sub-module.
  • These beam portions can take, indifferently for the invention, the form of rectilinear straight bands or for example the shape of tasks whose outline is less defined than that of the segments.
  • the light sources each consist of a semiconductor source, for example a light-emitting diode fixed to a printed circuit board.
  • the printed circuit board is fixed to the common support 14 separating the two sub-modules.
  • the complementary beam 13 capable of performing a non-dazzling main beam function.
  • one of the segments of the complementary beam can be switched off or attenuated in the event of detection of a vehicle in the area illuminated by this segment.
  • Each optical guide 38 has an input face 40 and an output face 42 so as to guide the light from the input face to the output face.
  • the optical guides further comprise a lower face, called a reflection face, 44 and an upper face, called a front face, 46 which extend between the ends of the input face and the output face, the reflection face being turned away from the cover while the front face is turned towards the cover 20.
  • the optical guides 38 are arranged so as to be in contact with the cover 20. They are oriented so as to be in contact with the cover only in the vicinity of the focal plane P of the optical projection device. As illustrated, it is the front face 46 of each optical guide which is in contact with the cover 20, the contact line 48 between each front face and the cover being in the focal plane.
  • the reflection face 44 has a substantially elliptical shape, a first focus of which coincides with the location of the light source 36 and a second focus of which, called the focusing focus, is located at the level of the adjoining edge of the front face 46 and the exit face 42, at the point of contact with the cover, so that, as can be seen on the Figure 7 , the light rays reflected in the optical guides (represented by dotted lines) exit the guide mainly at the top of the exit face. Part of these rays directly reaches the lens in the upper part while another part is reflected by a lower face of the cover to reach the lens in the lower part (see the thicker line).
  • the optical guides 38 are arranged in a transverse series, in the same number as the light sources 36, each guide being arranged opposite one of these light sources.
  • the series of three guides is arranged so as to be offset transversely relative to the center of the module.
  • this transverse offset is here due to the fact that there are two projectors, on the left and right of the vehicle. The superposition of the two left and right beams must give a complete complementary main beam. To achieve the width of this beam, we therefore offset transversely the guides in relation to the center of the lens so as to obtain an offset left or right beam and then the two beams are superimposed.
  • One of the guides arranged at one of the transverse ends of the series, has an output face whose upper edge, that is to say the edge adapted to be in contact with the cover, is trimmed to have a shape cooperating with the inclined plane 32 forming the step of the cover.
  • the optical guides are arranged in a transverse series perpendicular to the emission axis of the rays at the output of the module, and they are arranged in a fan-shaped arrangement.
  • a fan-shaped arrangement is understood to mean an arrangement according to which the respective downstream portions of the optical guides, carrying the output faces 42, are glued against each other and the respective upstream portions, carrying the input faces 40, are spaced transversely from each other.
  • these are made of a material allowing the diffusion of light rays by internal reflection from the entry face to the exit face.
  • a material could for example consist of polycarbonate (PC), polymethyl methacrylate (PMMA), silicone or glass.
  • Each of the guides 38 is produced individually and the guides are mounted relative to each other, on a fixing support 50.
  • the guides are here fixed to each other, in particular by gluing at the level of their downstream end portion, corresponding to their light ray exit face, and the spacing of the guides relative to one another at their upstream portion, corresponding to their light ray entry face, is ensured by the fixing of each guide to the support.
  • the fixing support 50 here takes the form of a transverse plate 52 whose transverse ends 54 are here fixed at the level of the transverse ends 26 of the cover 20, said plate carrying the guides at the level of their downstream end, as well as a frame 56 on which tabs 58 made of the same material as the frame allow the guides to be fixed at their upstream portion.
  • each guide 38 The downstream portions of the optical guides 38 are pressed against each other over a determined distance to form an overlap zone.
  • the output faces of each guide being arranged substantially in line with the cut-off edge 30 of the mask 20, that is to say substantially in the vicinity of the focal plane P of the optical projection device, it is understood that the overlap zones of the images formed by each guide are arranged upstream of the focal plane, which makes it possible to project a complementary beam whose different portions are smoothed to avoid vertical cutting, in the case of segmentation of the beam, which is too sharp.
