Definitions

  • the invention relates to lighting devices such as headlamps for motor vehicles.
  • the high beam function provides illumination of the entire width of the road in front of the vehicle.
  • the low beam function provides illumination of the lane in which the vehicle is located and reduced illumination of the adjacent lane in which vehicles are likely to be driving 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 certain cases make it possible to illuminate sufficiently far the side of the road located beyond this adjacent lane. However, this constitutes a source of danger. For example, if a pedestrian located on this shoulder is about to cross the road, he will not be seen early enough by the driver.
  • an adaptive light function has been proposed which enables certain parts of the scene located in front of the vehicle and in particular the side located beyond the adjacent lane to be illuminated at a great distance and selectively.
  • 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 produced in separable parts, each guide being coupled to a light source and able 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 light pixel on the scene in front of the vehicle.
  • each guide being produced by a separate part, it is necessary to fix each of the guides has a support of the lighting system. This constitutes long and tedious operations, and an additional cost due to the fact that it is necessary to provide fixing means for fixing all the light guides.
  • the large number of light guides requires numerous operations for adjusting the positioning and orientation of the light guides relative to one another 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 being numerous and of relatively small dimensions, it is not easy to handle them with a view to their installation in the lighting system.
  • An object of the invention is to overcome these drawbacks and therefore to reduce the number of parts contained in the lighting system, without however reducing the number of light guides and harming 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 which it is necessary to perform, whether they are operations for adjusting the positioning of the light guides with respect to each other. others or operations of fixing the light guides to a support of the lighting system.
  • the two parts forming the guides are easier to handle than the separable light guides of the prior art because the parts are larger than the separable guides.
  • the light guides are distributed over the first and second guide pieces so that, 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 direction of alignment and an optical axis of the optical projection device, has the general shape of a comb comprising teeth forming the light guides, and hollows alternating with the teeth.
  • the guide pieces thus have a simple shape which makes it possible to simply fit the guide pieces into one another, the teeth of the pieces forming the light guides.
  • a free surface of the first guide piece has reliefs for folding down the light beams intended to focus the light rays emitted by each light source towards the light guide with which it is coupled.
  • the guide parts are made of the same material, such as only silicone, these two guide pieces being 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 made.
  • the glue fills any air pockets trapped between the nested guide pieces, this material not substantially deflecting 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 the different guides in different ways, and the light spots are then distorted. Thanks to the glue, the deviations do not take place, or are then weak, and therefore the light spots all have the same shape. Furthermore, the glue makes it possible to effectively secure the two guide pieces to one another.
  • Another solution consists in deliberately leaving a thin layer of air where it is inevitable in the absence of glue between the ends of the guides of the first guide part and the optical projection device. These layers only cause losses by vitreous reflection which can be compensated for by the flow of the corresponding light sources, for example by choosing sources having a “bin” code, or luminosity code, greater than that of the light sources opposite. light guides of the second guide piece or by supplying these light sources with a current greater than the current supplying the light sources opposite the light guides of the second guide piece.
  • the second guide part is molded onto the free surface of the optical projection device or integrally formed therefrom.
  • two adjacent light guides are separated by an air space.
  • each light guide has, in any plane perpendicular to the optical axis of the optical projection device, a section of polygonal shape, generally rectangular or trapezoidal, with two horizontal sides and two vertical or oblique sides.
  • This cross-sectional shape of the light guides is conducive to guiding the light and is also simply achievable.
  • each guide associated with a light source is delimited by two said end contour lines, preferably two straight 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 optical projection device.
  • each light strip generated by the lighting system are blurred.
  • the gradient of light intensity in these areas is low, and the transition between the illuminated areas and the unlit areas is smooth.
  • each guide associated with a light source is delimited by two so-called lateral contour lines, preferably two straight segments, imposing the shape of two lateral edges of the light strip generated by the light source associated with the guide, these two lateral contour lines being substantially included in the focal plane of the optical projection device.
  • the light strips generated by the lighting system have sharp side edges. This prevents the light bands from overlapping, which could adversely affect the operation of the lighting system.
  • This lighting system 1 comprises a lighting module 2.
  • This lighting module 2 comprises a set 4 of light sources 6, and means 8 for guiding the light emitted by the light sources 6.
  • the means of guide 8 guide the light towards an optical projection device 10 intended to project the light which is emitted by the light sources 6 and which is guided by the guide means 8 outside the lighting system 1, towards the front of 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 X direction and a focal surface 10P here plane, the free surface 12 of the lens being located at a distance from the focal surface 10P.
  • a complementary optical projection device 14 such as a projection lens can be placed in front of the optical projection device 10 by considering the trajectory of the light emitted by the light sources 6.
  • the light sources 6 each comprise a light emitting diode optionally of the laser diode type, emitting substantially monochromatic light.
  • Each laser diode is coupled to wavelength converting means for converting substantially monochromatic light to white light.
  • These wavelength conversion means are for example constituted by a block, in the form of a rectangular parallelepiped, of wavelength converter material, for example a phosphorescent or luminescent material, such as YAG crystals (Yttrium Aluminum Garnet). doped with rare earths, zinc sulphide (ZnS), etc.
  • White light is emitted by the wavelength converting means from a surface of these means.
  • the light sources 6 each have a generally rectangular light emitting face. These light emitting faces are substantially centered on the same straight line defining a direction of alignment 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 light spots forming lighting.
  • the light guide means 8 are placed opposite the light emitting faces of the light sources 6. They are intended to guide the light emitted by each light source 6 towards the optical projection device 10.
  • the means of 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 conversely each light source 6 is coupled with a light guide 18
  • the light guides 18 are arranged so as to form, from the light emitted by the light sources 6 and in cooperation with the projection optical device 10, one light spot per light source 6, each light spot having a light strip shape. We will see below how these light spots are generated.
  • 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 guide piece 20.
  • the guide pieces 20, 22 thus fit together effectively while 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 made. This ensures that any air pockets located between the two guide pieces 20, 22 are filled with this adhesive. Given that 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 only slightly deflects the light propagating in the guide means 8 relative to the desired trajectory. It is also possible to provide for not having to resort to an adhesive and to use any other fixing means known to those skilled in the art. These fixing means may in particular extend over the side surfaces of the guide pieces 20, 22, that is to say those extending substantially perpendicular to the vertical direction Z. In fact, 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, considering the direction of alignment 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 therefore to improve the fixing of the guide pieces 20, 22 the 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 down the light beams 24 intended to focus the light rays emitted by each light source 6 towards the light guide 18 with which it is coupled.
  • These folding reliefs 24 form light entry surfaces 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 interior of the guide. light 18 with which the source 6 is coupled. It follows that one increases the quantity of light which penetrates inside the light guides 18 in order to increase the light intensity of the beam exiting the lighting system 1 and that one avoids as much as possible d 'injecting light from a light source 6 to the light guides 18 adjacent to the one paired with it.
  • the F beams shown on the figure 2 illustrate the effects of folding reliefs 24.
  • the second guide piece 22 is attached to the free surface 12 of the optical projection device 10.
  • the second guide piece 22 is overmolded on the free surface 12 of the optical projection device 10. Thanks to the overmolding, it It is not necessary to provide fixing means specifically dedicated to fixing the second guide piece 22 on the free surface 12. It is nevertheless possible to provide for fixing the second guide piece 22 on the free surface 12 by any other means. . Provision can also be made for the second guide piece 22 to be integral with the projection lens.

Indeed, referring to the figure 4 , it can be seen that all the teeth of the first guide piece 20 are molded against the undercut. The shape of the light guides 18 and therefore those of the light spots generated by the lighting system 1 is modified in this way. These undercuts are permitted by the release axis of the guide piece 20, perpendicular to the plane of the figure 4 .
  • the engagement of the first guide part 20 in the second guide part 22 is effected by translation parallel to the Z direction.
  • the undercut molding of the first guide piece 20 makes it possible to provide an air space 25 between each light guide 18, these air spaces 25 being intended to separate the light guides 18.
  • Each air space 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 light because such a shape reduces the maximum angle at which a light ray propagating in a guide 18 can meet a side wall. of said guide 18, that is to say a normal wall substantially included in a horizontal plane.
