Definitions

  • the invention relates to a lighting or signaling device for a motor vehicle which comprises a light-guiding sheet.
  • Such a device is known from the document EP 1 126 209 .
  • 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. 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 forward so that part of the scattered light rays come out of the light guide through the opposite portion of the cylindrical face to form a linear 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 around the headlamp.
  • 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 light beam obtained by such a device is very low even if the light source arranged at the input end of the light guide is very powerful.
  • 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 at vicinity of the light source is greater than remote 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.
  • the invention proposes a lighting and / or signaling device of the type described above, characterized in that the guide ply comprises several angular sectors around the axis of the source, each angular sector forming a portion of the return wafer, each portion of the return wafer being shaped in a circular arc centered on the axis of the source so that the propagation plane of each light beam reaching this portion of the return wafer is perpendicular to any point at the portion of the return wafer, and in that the wafer portion is inclined so that the light rays are reflected generally towards the optical axis by passing through one of the guide faces to form the light beam; the return wafer being thus formed of a succession of frustoconical portions of axis coinciding with the optical axis, at least two portions of the return wafer being in a circular arc of different radii.
  • FIG. 1 a lighting 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 "O".
  • the lighting device 10 comprises in particular a light-guiding sheet 12 which is in the form of an angular sector of plane disk of constant thickness.
  • a normal orientation "N" orthogonal to the guide ply, a radial orientation “R” perpendicular to the normal and a non-limiting orientation, will be adopted locally at all points of the guide ply 12, and in a non-limiting manner. directed from the center of the disc angular sector outwards, and a tangential orientation "T" perpendicular to the normal "N” and radial "R” orientations.
  • 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. Both front 14 and rear 16 are parallel to each other.
  • the guide ply 12 is delimited radially by an outer circular arcuate return slice 18 and an inner arc-shaped entrance slice 20 having a radius smaller than that of the slice. reference.
  • the two arcs forming the return 18 and input 20 are centered on a common axis called "light source S" which is normal to the guide ply 12.
  • the source axis "S" coincides with the optical axis "O".
  • the guide ply 12 also has two lateral edges 22.
  • the guide ply 12 is made of a transparent material whose refractive index is greater than the refractive index of the medium. wherein the lighting device 10 is intended to be immersed, for example air.
  • a light ray introduced into the thickness of the web by its input slice with an incident angle relative to the normal "N" which is greater than a refraction limit angle is likely to be reflected completely by the faces guide 14, 16.
  • the light ray is thus guided in the thickness of the guide web by successive reflection between the two guide faces 14, 16.
  • the lighting device 10 also comprises a point light source 24 which is arranged near or in contact with the entrance wafer of the light 20.
  • the light source 24 is for example a halogen lamp, or preferably a light emitting diode.
  • the light source is capable of emitting a light cone 26 in generally radial directions in a ring around the normal source axis "S", such as an LED or light emitting diode called “Side-Emitter” which emits rays. light in a range for example of 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 ".
  • the side emitter LED also called lateral emission LED, is arranged so that its emitting surface is in a through opening formed in a coupling zone "ZC" with the light source 24, that is, that is, so that its emitting surface faces the inner light input wafer 20.
  • Radii r emitted radially by the LED are represented and all depart in the thickness of the coupling zone "ZC" and penetrate into the guide ply 12 by the input wafer 20.
  • the emission cone C of the LED is also schematically represented, it corresponds approximately at the level of the input slice to the thickness of the guide ply.
  • the coupling zone "ZC” allows a coupling between the guiding layer 12 and the light source 28, so that the light rays 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 ply 12 but not in the other of the faces.
  • the source 24 is here a Lambertian type LED, or LED axial emission.
  • it is a LED devoid of 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 said light source are then redirected radially at the level of said 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 24 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”.
  • a lambertian-type LED with a protective dome is used.
  • Such an LED is for example known under the trade name "Led Rebel”.
  • the LED 24 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 at the figure 9 the rays that 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 output slot.
  • This is for example a kind of "truncation” so that the reflection zone "CO” has a plane 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 opposed to the LED 24.
  • the top of the flat face is located between the top of the cone and the base thereof, on the side of the output wafer (for example on the left on the Figures 9 and 10 ).
  • 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.
