Definitions

  • the invention relates to a lighting or signaling device for a motor vehicle which comprises a light-guiding sheet.
  • the shape of the lighting and / or signaling lights plays a key role in the search for a style and an original aesthetic that will allow the motor vehicle to be recognized by far.
  • a light guide is a cylinder of transparent material that forms a kind of "pipe" in which light rays enter through a first input end. The light rays are then guided along the light guide by successive total reflections on its cylindrical outer face.
  • a rear portion of the cylindrical face of the light guide has irregularities, such as diffusion streaks, which make it possible to diffuse part of the light rays towards the front of the light guide. whereby a portion of the scattered light rays exit the light guide through the opposite portion of the cylindrical face to form a light beam.
  • the light guide may for example be shaped into a ring that surrounds the front perimeter of a low beam headlamp so as to emit an annular beam of light.
  • the input end portion of the light guide is then bent so that the input end of the light rays is arranged outside the ring formed by the light guide.
  • the material constituting the lighting or signaling device causes a certain absorption of the light rays which pass through it, which results in losses that are all the greater due to the distance away from the light source.
  • the brightness in the vicinity of the light source is greater than at a distance from this source, and therefore a lack of homogeneity.
  • part of the light rays introduced into the light guide by the bent input portion directly reaches the opposite face of the light guide thus causing the appearance of a very bright point relative to the remainder of the annular beam.
  • FIG. 1 shows a lighting or signaling device 10 for a motor vehicle.
  • the lighting device 10 is capable of emitting a linear light beam "F" along a generally longitudinal optical axis "A".
  • the lighting device 10 comprises in particular at least one light guiding ply 12 which is in the form of a spherical cap portion.
  • the lighting device 10 shown in Figure 1 comprises a single guide web 12 forming a portion of an imaginary base sphere 13.
  • the guide ply 12 is thus delimited in the direction of the thickness, by a front face 14 and a rear face 16 for guiding the light.
  • the two front 14 and rear 16 faces are parallel to each other on at least a portion of the web.
  • the guide ply 12 is in particular delimited laterally by a front edge 18 of the light rays and by a rear light reflection slice 20.
  • the ends of the reflection slice 20 are directly connected to the end of the outlet edge 18 so as to form the outer contour of the guide ply 12.
  • the reflection slice 20 may be constituted by a reflective layer, such as an aluminized coating on the outer face of the reflection slice 20. It can also be provided that between the two junctions between the reflection slice 20 and each of the faces 14 and 16 of the guide web 12, the output wafer 18 has a stop extending along this wafer and separating it into two faces forming an angle between it. Thus an incident ray RI will undergo a double reflection, a first on one of the faces and a second on the other face, to be emitted in the plane of propagation reflected "Mr".
  • the outline of the light output wafer 18 here forms a plane arc, that is, the edge of the output wafer is defined by the intersection of the base sphere 13 and a plane.
  • the outer contour of the guide ply 12 also comprises inactive transition zones 22 which are interposed between the reflection slice 20 and the outlet slice 18.
  • the guide ply 12 also comprises an orifice 24 which is delimited by a peripheral edge 26 for entering the light.
  • the orifice 24 is here through.
  • a light source 28 is arranged in the orifice 24 near or in contact with the input section of the light beams 26.
  • the light source 28 is capable of emitting light rays in a generally radial direction around a source axis "S" which is normal to the guide ply 12. More precisely, the light source 28 is capable of emitting a a range of light rays radially at least rearward towards the reflection slice 20.
  • the light source 28 is here a light emitting diode or "LED” called “Side-Emitter” which emits light rays in a range for example about 30 ° on either side of the radial direction in a meridian plane to the source axis "S" and which is likely to extend around the source axis "S", for example 360 ° in a plane normal to the source axis "S".
  • LED light emitting diode
  • the "side emitter” LED also called lateral emission LED, is arranged so that its emitting surface is in a through opening formed in a "ZC" coupling zone with the light source 28.
  • R radially radiated by the LED are represented and all depart in the thickness of the coupling area "ZC”.
  • the emission cone C of the LED is also schematically represented, it corresponds approximately to the level of the input slice to the thickness of the guide ply.
  • the coupling zone "ZC” allows a coupling between the guide layer 12 and the light source 28, so that the radii light emitted by said light source are propagated radially at said coupling area around a source axis "S".
  • the orifice is opening only in one of the guide faces of the guide web 12 but not in the other faces.
  • the source 28 is here a Lambertian type LED, or axial emission LED.
  • it is - a LED devoid of a dome, for example an LED available under the trade name "Golden Dragon” -. It emits in a half space. It is arranged so that its emitting surface is flush with the surface of the coupling zone "ZC" which has been arranged in such a way that the light rays emitted by the light source are then redirected radially at the level of the said zone. coupling around a source axis "S".
  • the coupling zone “ZC” locally has an inlet zone in the form of a convex convex surface "B" on the side of which the LED 28 is located, and on the opposite face and opposite this convex face.
  • B an area approaching the shape of a shape complementary to a cone "CO”.
  • this time use is made of a lambertian type LED with a protective dome.
  • a lambertian type LED is for example known under the trade name "Led Rebel”.
  • the LED 28 is disposed in the coupling zone "ZC" so that the dome is inserted into a non-through opening provided in the coupling zone.
  • this opening there is a convex curved surface "B” and on the opposite face of the coupling zone a fitted surface of a zone approaching the shape of a shape complementary to a "CO” cone, so that as in FIG. 12, the rays which reach it go back into the coupling zone "ZC" by total reflection.
  • the cone "CO” may also have a deformed area to return the rays that without this area would directly reach the edge of output.
  • This is for example a kind of "truncation” so that the reflection zone "CO” has a flat face.
  • the periphery of the cone corresponds to a circle.
  • the top of this triangle opposite this base is located on the cone between the two faces of the guide ply, preferably near the top of the cone.
  • This flattened face is located next to the exit slice. All the rays emitted above the conical section portion will therefore be distributed around the source axis "S" within an angular interval corresponding to the circular portion of the cone section on the face opposite to the LED 28.
  • the top of the flat face is located between the top of the cone and the base thereof, the side of the output edge (eg left in Figures 12 and 13).
  • the angular interval is greater than 180 °.
  • the reflection slice surrounds this zone conical profile and thus the set of rays reflected around the source axis "S" is reflected a second time by the reflection slice.
  • the rays emitted above the plane face will be reflected in the same direction and directly towards the output edge, the base of the triangle constituting the plane face perpendicular to the optical axis.
  • the invention makes it possible to use LEDs with very different characteristics, which can emit either radially, axially or in a half-plane. It is then necessary to arrange the coupling zone accordingly, for example by making an opening therethrough or not to insert all or part of the LED, and providing optical means when necessary (especially for the LEDs emitting in half a plane) so that the maximum of the light emitted by the LED propagates well in the thickness of the coupling zone without loss to the rear reflection zone 20.
  • the entrance wafer of the light 26 is thus surrounded by the outer contour including the exit wafer 18 and the reflection wafer 20 of the guide wafer 12.
  • the input wafer 26 can not not be closed. Indeed, there is a sector of this slice 26 inefficient, located vis-à-vis the reflection slice 20, and for which the rays reflected by the slice 20 return to the input slice 26. These light rays are not used in the lighting or signaling device, they are lost. We can take advantage of this observation to not have material in this region, to facilitate the demolding of the guide web.
  • the guide sheet 12 is made of a transparent material whose refractive index is greater than the refractive index of the medium in which the lighting device 10 is intended to be immersed, for example air.
  • a light ray introduced into the thickness of the ply 12 by its input slice 26 with an incident angle relative to the normal "N" which is greater than a limit angle of refraction is likely to be reflected totally by the guide faces 14, 16.
  • the light ray is thus guided in the thickness of the guide sheet by successive reflections between the two guide faces 14, 16.
  • the incident light rays that go backwards are intended to be reflected by the reflection slice 20, and then the light rays thus reflected are directed towards the output slice 18.
  • the reflected light rays thus come out. by the output slice 18 tangentially to the guide ply 12 to form the linear "F" light beam in an arc.
  • an incident light ray will be defined as a light ray which is emitted by the light source 28 in the direction of the reflection slice 20.
  • the light rays emitted by the light source 28 directly towards the slice of light output 18 are therefore not included in this definition of incident rays.
  • the light rays that are emitted forward by the source Luminous 28 directly towards the output slot 18 will be called "direct".
  • the light source 28 may also consist of an incandescent lamp, for example a halogen lamp, with an axial filament, inserted in the contour delimited by the entrance wafer 26. It will then be advantageous to provide in this case for a zone the guide ply, in the vicinity of the entrance slice 26, is made of glass, while the rest of the ply will be made of plastic material overmoulded on this glass area. Such a design makes it possible to overcome the thermal problems that could generate the use of an incandescent source.
  • an incandescent lamp for example a halogen lamp
  • the input slice portion 26 which is oriented forwardly is thus shaped to distribute the direct light rays substantially uniformly along the output wafer 18. As shown in FIG. 2, the front portion 29 the input wafer 26 is striated so as to disperse the light rays into a fan that covers at least the entire output wafer 18.
  • the direct light rays are collimated in the plane tangent to the web, it is also possible to place on the zone of the input slice corresponding to the direct rays, in front of the LED with respect to the optical axis, a zone of the shape of a curved convex surface, facing the LED 28, the surface being curved in the direction of the LED.
  • the convex zone can be put in place of the striated zone 29 shown in FIG. 2.
  • the orifice inside which the LED 28 is placed has a shape such that it has on the one hand a concave shape, at the rear of the LED 28 with respect to the optical axis "A" of the lighting device and whose section is preferably a semicircle, and on the other hand a convex convex shape at the front of the LED.
  • the concave shape and the convex shape are separated by a flat portion, allowing the light source to be positioned closer to the concave shape at the rear than the convex shape at the front. This removes the convex shape of the source and thus reduces the section of the cone of direct rays reaching the convex form.
  • the entrance slice 26 is slightly frustoconical, so as to optimize the mean direction of the rays in the ply in the meridian plane relative to the tangent to the ply.
  • the light source 28 is arranged near the input wafer 26.
  • the light source 28 is associated with a reflection face 30 which is arranged opposite the wafer. entrance of light rays.

  • the reflection slice 20 is here perpendicular to the guide faces 14, 16 of the guide ply 12.
  • This design is made possible firstly by the shape of the base sphere portion 13 of at least one rear portion 12R of the guide sheet which is traversed by the incident light rays between the light source 28 and the reflection slice 20, and on the other hand by the particular shape given to the contour of the reflection slice 20.
