Definitions

  • the invention relates to lighting devices such as projectors for motor vehicles.
  • the high beam function provides illumination the full width of the road in front of the vehicle.
  • the low beam function provides illumination of the vehicle lane and reduced illumination of the lane adjacent to it and in which vehicles may roll in the opposite direction. In this way, the occupants of the latter are not dazzled.
  • the dipped beam function in its most usual form does not in some cases illuminate far enough the side of the road beyond this adjacent lane. This is a source of danger. For example, if a pedestrian on that side of the road is about to cross the road, it will not be seen early enough by the driver.
  • an adaptive fire function has been proposed which makes it possible to illuminate at a great distance and selectively certain parts of the scene in front of the vehicle and in particular the aisle located beyond the adjacent lane.
  • an observation device analyzes the scene and selects the areas to be illuminated.
  • the lighting system of DE-10 2011 053 232 comprises a lighting module comprising light sources and light guides made in separable parts, each guide being coupled to a light source and adapted to guide the light emitted by the sources towards the front of the vehicle.
  • each guide is able to form, from the light emitted by the light source with which it is coupled, a luminous pixel on the stage in front of the vehicle.
  • each guide being made by a separate part, it is necessary to fix each of the guides to a support of the lighting system. This is a long and tedious operation, and an additional cost because it is necessary to provide fixing means for fixing all the light guides.
  • the large number of light guides imposes many operations of adjustment of the positioning and orientation of the light guides relative to each other so that the selective beam correctly cuts the scene in front of the vehicle. This constitutes other long and tedious operations.
  • the separate parts forming the various light guides are numerous and relatively small, it is not easy to handle them for installation in the lighting system.
  • An object of the invention is to overcome these disadvantages and thus reduce the number of parts contained in the lighting system, without reducing the number of light guides and impair the operation of the lighting system.
  • the light guides are made in two parts only regardless of the number of light sources and light guides. This makes it possible to reduce the number of adjustment operations that it is necessary to perform, whether it is to adjust the positioning of the light guides relative to each other. other or operations of fixing the light guides to a support of the lighting system.
  • the two pieces forming the guides are easier to handle than the separable light guides of the prior art because the pieces are larger than the separable guides.
  • the light guides are distributed over the first and second guide pieces so that, in considering the direction of alignment of the light sources, the light guides carried by the first guide piece alternate with the light guides carried. by the second guide piece.
  • each guide piece in section in a plane parallel to the plane defined by the straight line defining the alignment direction and an optical axis of the projection optical device, has a general comb shape comprising teeth forming the light guides, and hollows alternating with the teeth.
  • the guide pieces thus have a simple shape that allows to simply fit the guide pieces into one another, the teeth of the parts forming the light guides.
  • a free surface of the first guide piece has reliefs of folding light beams for focusing the light rays emitted by each light source to the light guide with which it is coupled.
  • the guide pieces are made of the same material, such as silicone, these two guide pieces being fixed to each other by means of an adhesive having an optical index close to that of the material in which the guide pieces are made.
  • the glue fills any trapped air pockets between the nested guide pieces, this material not substantially deviating the light propagating in the light guides. Due to manufacturing tolerances, the air pockets have different sizes and shapes. As a result, they deflect the light in different guides in different ways, and the light spots are then deformed. Thanks to the glue, the deviations do not take place, or are weak, and therefore the light spots all have the same shape. Moreover, the adhesive makes it possible to effectively secure the two guide pieces together.
  • Another solution is to deliberately provide a thin layer of air where it is inevitable in the absence of glue between the ends of the guides of the first guide piece and the projection optical device. These layers cause only losses by glassy reflection which can be compensated for by the flow of the corresponding light sources, for example by choosing sources having a "bin" code, or brightness code, higher than that of the light sources facing each other. light guides of the second guide piece or by supplying these light sources with a current greater than the current supplying the light sources facing the light guides of the second guide piece.
  • the second guide piece is overmolded on the free surface of the projection optical device or material of it.
  • two adjacent light guides are separated by an air gap.
  • each light guide has, in any plane perpendicular to the optical axis of the projection optical device, a section of polygonal shape, generally rectangular or trapezoidal, with two horizontal sides and two vertical or oblique sides.
  • each guide associated with a light source is delimited by two so-called end contour lines, preferably two line segments, imposing the shape of two longitudinal ends of the light strip generated by the light source associated with the guide, these two end contour lines being located at a distance from a focal surface of the projection optical device.
  • each light band generated by the lighting system are blurred.
  • the luminous intensity gradient in these areas is low, and the transition between the illuminated and the unlit areas is smooth.
  • each guide associated with a light source is delimited by two so-called lateral contour lines, preferably two line segments, imposing the shape of two lateral edges of the light band generated by the light source associated with the guide, these two lateral contour lines being substantially included in the focal plane of the projection optical device.
  • the light bands generated by the lighting system have sharp lateral edges. In this way, it prevents the light bands overlap, which could affect the operation of the lighting system.
  • This lighting system 1 comprises a lighting module 2.
  • This lighting module 2 comprises an assembly 4 of light sources 6, and means 8 for guiding the light emitted by the light sources 6. 8 guide the light towards an optical projection device 10 for projecting the light which is emitted by the light sources 6 and which is guided by the guide means 8 to the outside of the lighting system 1, towards the before the vehicle.
  • the optical projection device 10 is here formed by a projection lens in the general shape of a hemisphere.
  • the lens has a free surface 12 in the form of a disc.
  • the lens has an optical axis 10A substantially parallel to the direction X and a focal surface 10P here planar, the free surface 12 of the lens being located at a distance from the focal surface 10P.
  • a complementary projection optical device 14 such as a projection lens may be placed in front of the optical projection device 10 by considering the path of the light emitted by the light sources 6.
  • the light sources 6 each comprise a light-emitting diode, possibly of the laser diode type, emitting substantially monochromatic light.
  • Each laser diode is coupled to wavelength conversion means for transforming the substantially monochromatic light into white light.
  • These wavelength conversion means are for example constituted by a rectangular parallelepiped shaped block, a wavelength converter material, for example a phosphorescent or luminescent material, such as YAG (Yttrium Aluminum Garnet) crystals. rare earth doped, zinc sulphide (ZnS), etc.
  • the white light is emitted by the wavelength converting means from a surface of these means.
  • the light sources 6 each comprise a face of generally rectangular shape of light emission. These light-emitting faces are substantially centered on the same straight line defining an alignment direction 16 of the light sources 6 substantially parallel to two opposite sides of each light-emitting face.
  • the alignment direction 16 is substantially parallel to the Y direction.
  • the number of light sources 6 is preferably greater than or equal to three and the highest possible, each source 6 producing one of the luminous spots forming lighting. Alternatively, it may be provided to replace the diodes by white light sources of another type, in which case we will dispense with wavelength conversion means.
  • the light guiding means 8 are placed facing the light-emitting faces of the light sources 6. They are intended to guide the light emitted by each light source 6 to the projection optical device 10.
  • the means for light guide 8 comprise light guides 18 in number equal to the number of light sources 6.
  • Each light guide 18 is coupled with a light source 6, and reciprocally each light source 6 is coupled with a light guide 18
  • the light guides 18 are arranged to form, from the light emitted by the light sources 6 and in cooperation with the optical projection device 10, a light spot by light source 6, each light spot having a form of light band. We will see in the following how these light spots are generated.
  • the light guides 18 are distributed on first 20 and second 22 separate guide parts of complementary shapes, nested one inside the other as is apparent from the figure 2 .
  • each guide piece 20, 22 In section in a plane parallel to the plane defined by the line defining the alignment direction 16 and the optical axis 10A of the projection optical device 10, each guide piece 20, 22 has the general shape of a comb comprising teeth forming the light guides 18, and recesses alternating with the teeth.
  • the teeth of the first guide piece 20 are able to penetrate into the recesses of the second guide piece 22, and conversely, the teeth of the second guide piece 22 are able to penetrate into the recesses of the first 20.
  • the guide pieces 20, 22 thus interlock efficiently with one another by minimizing the air volumes between the guide pieces 20, 22.
  • the two guide pieces 20, 22 are made of the same material, such as silicone or polycarbonate. These two guide pieces 20, 22 are for example fixed to one another by means of an adhesive having an optical index close to that of the material in which the guide pieces are produced. This ensures that any air pockets between the two guide pieces 20, 22 are filled by this glue. Since it has an optical index close to that of the material of the guide pieces 20, 22, for example equal to plus or minus 0.1, the glue deviates only very little the light propagating in the guide means 8 relative to the desired trajectory.
  • These fixing means may in particular extend on lateral surfaces of the guide pieces 20, 22, that is to say those extending substantially perpendicular to the vertical direction Z. Indeed, in this position, the fixing means would not hinder the propagation of light in the lighting system 1.
  • the light guides 18 are distributed over the first 20 and second 22 guide pieces so that, in view of the alignment direction 16 of the light sources 6, the light guides 18 carried by the first guide piece 20 alternate with the light guides 18 carried by the second guide piece 22.
  • Such an arrangement makes it possible to increase the contact surfaces between the two guide pieces 20, 22 and thus to improve the fixing of the guide pieces 20, 22 one with the other.
  • the first guide piece 20 is placed opposite the light-emitting faces.
  • a free surface of the first guide piece 20 has reliefs for folding the light beams 24 for focusing the light rays emitted by each light source 6 towards the light guide 18 with which it is coupled.
  • These folding reliefs 24 form input surfaces of the light in the light guides 18.
  • These folding reliefs 24 form converging diopters and are able to focus the light emitted by each light source 6 towards the inside of the guide light 18 with which the source 6 is coupled. It follows that we increase the amount of light that penetrates inside the light guides 18 to increase the light intensity of the beam coming out of the lighting system 1 and that we avoid as much as possible d injecting light from a light source 6 towards the light guides 18 adjacent to the one that is paired with it.
  • the beams F represented on the figure 2 illustrate the effects of the folding reliefs 24.
  • the second guide piece 22 is attached to the free surface 12 of the projection optical device 10.
  • the second guide piece 22 is overmolded on the free surface 12 of the projection optical device 10. Thanks to the overmolding, it it is not necessary to provide fastening means specifically dedicated to fixing the second guide piece 22 to the free surface 12. It will nevertheless be possible to fix the second guide piece 22 on the free surface 12 by any other means . It can also be provided that the second guide piece 22 is integral with the projection lens.
  • the second guide piece 22 is overmolded on the free surface 12 of the projection optical device 10 in a manner known per se.
  • the first guide piece 20 is formed, for example by molding, giving the teeth of this first guide piece 20 undercut shapes. Indeed, by referring to the figure 4 it will be seen that all the teeth of the first guide piece 20 are molded undercut. This changes the shape of the light guides 18 and thus those of light spots generated by the lighting system 1. These undercuts are allowed by the demolding axis of the guide piece 20, perpendicular to the plane of the figure 4 .
  • the engagement of the first guide piece 20 in the second guide piece 22 is carried out by translation parallel to the direction Z.
  • the undercut molding of the first guide piece 20 allows to provide an air gap 25 between each light guide 18, these air strips 25 being intended to separate the light guides 18.
  • Each blade of air 25 has a thickness of the order of a few tens of micrometers on average.
  • the undercut shape of the first guide piece 20 also allows the light guides 18 to better guide the light because such a shape reduces the maximum angle at which a light ray propagating in a guide 18 can meet a side wall. said guide 18, that is to say a wall of normal substantially included in a horizontal plane.
  • the molding operations described above allow the guide pieces 20, 22 to have a clearance with respect to each other almost zero, generally of the order of 200 ⁇ m or less, according to the machining tolerances. applied.
  • glue is added to the recesses of the second guide piece 22 before the first guide piece 20 is fitted therein to prevent the presence of undesirable air pockets between the two guide pieces 20, 22.
  • each light guide 18 has, in any plane perpendicular to the optical axis 10Adu projection device 10, a section of generally rectangular shape with two horizontal sides and two vertical sides.
  • the light spots generated by the lighting system 1 are generally in the form of a rectangle, although the undercut molding of the first guide piece 20 provides each light spot a substantially trapezoidal shape.

  • Each light spot 26 has a general shape of substantially rectangular light band and elongate in the vertical direction Z.
  • Each light spot 26 has lateral edges slightly inclined relative to the vertical direction Z, an angle of about a few degrees. This inclination is caused by the undercut molding of the first guide piece 20 and the undercut molding of the second guide piece 22. These properties of the light spots 26 are also obtained for a lighting system 1 according to the first embodiment of the invention.
  • each band 26 The lateral edges of each band 26 are sharp while the end edges of each band 26 are blurred. In this way, the light strips 26 are clearly demarcated relative to each other so that they do not overlap, and the light intensity transitions at the high and low ends of the light strips 26 are soft, which improves the comfort of view of the driver of the vehicle.
