Definitions

  • the invention relates to the field of lighting and / or signaling, in particular for motor vehicles. It relates more particularly to a projector light module and an associated primary optical element in this module.

  • projectors or headlights
  • These projectors, a left projector and a right projector include one or more light modules adapted to generate and direct an intermediate light beam, the addition of which forms said overall light beam.
  • These headlamps can generally be used in two lighting modes: a first "high beam” mode producing a high beam and a second "low beam” mode producing a Code beam.
  • the “high beam” mode allows the road to be strongly illuminated far in front of the vehicle.
  • the “low beam” mode provides more limited illumination of the road, but nevertheless offers good visibility, without dazzling other road users.
  • the two lighting modes, "high beam” and “low beam” are complementary, and we switch from one to the other depending on the traffic conditions. It is known practice to produce the main beam beam by adding the Code beam and a complementary beam, joined with the Code beam at the cut-off edge.
  • the Code beam is generated by the sole switching on of means specific to the second “low beam” mode, while the High beam is generated by the simultaneous switching on of the means specific to the second “low beam” mode and means specific to the first mode " Redlights ".

  • Light modules are known for producing a selective beam in which optical guides are arranged side by side, each being illuminated by a respective light source so that the light beam at the output of the module is cut into contiguous regions that are can turn off or on according to instructions of detecting a nearby vehicle.
  • the shape and arrangement of the guides with respect to each other in a module of a projector must be very precise in order to be able to produce an intermediate beam at the output of the module which is homogeneous and smooth when all the segments are on, and on the other hand to be able to present an intermediate beam complementary to the intermediate beam produced at the output of the other headlight.

  • the first left end guide 8j may include a left side spreading face 82 shaped to continuously widen laterally the cross section of the guide from its entry face to its exit.
  • the left side face 82 can be curved to flare from the rear inlet face 80 of the first left end guide 8j to its outlet 81. The lateral widening of the first left end guide 8j allows spreading.
  • the light module shown on the figures 1 and 2 is intended to equip a left headlight of a motor vehicle, and that the figures 3 and 4 correspond to beams produced by modules in this left projector. And it is understood that the light module intended for a right headlight of a motor vehicle symmetrically comprises a first left end light guide 8a having a flared right side face similar to the left side face of the first left end guide. 8 days from the figure 2 .
  • each of the first guides 8 has the effect of reducing the aperture of the light rays emitted by the primary light sources 1 and 2, the rays entering the light guides 8 and 9 being deflected by the laws of refraction . Further, at the interface between each light guide 8,9 and the correcting part 6, the light rays are not deflected due to the connection between the first guides 8 and the correcting part 6. Thanks to this, the reduced shelf opening is retained. Finally, the light rays coming out of the corrective part 6 via the exit face 61 are not or only slightly deflected thanks to the spheroidal dome shape of the exit face 61.
  • the half-spherical correcting part 6 being centered on the junction at the exit of one of the first guides and of the second guide, a ray coming from the exit plane of this first guide at the level of the optical axis A 1 is normal or almost normal to the outlet face 61 and is therefore not deflected at the interface between the correcting part 6 and the surrounding air.
  • a ray coming from a zone away from the optical axis is bent towards this optical axis.
  • the refraction at the interface between the correcting part 6 and the surrounding medium (air) is in a way “compensated” by the spherical, or substantially spherical, shape of the outlet face 61.
  • the correcting part 6 also makes it possible to correct the field aberrations of the optical system and thus ensure good quality imaging:
  • the secondary optical element 4 is here a converging optical lens having the axis A 1 as its optical axis .
  • the distance separating the corrective part 6 and the secondary optical element 4 is strictly greater than zero and adapted so that the plane in which the outlets of the first light guides extend substantially coincides with the object focal plane of the projection system formed by the secondary optical element 4 and by the primary optical element 3. Thanks to this, the light module is adapted to create an infinite image of the secondary light sources formed at the output ends of the guides. It is thus possible to generate several light segments, with good imaging, using the same primary optical element 3 and from light guides positioned on or outside the optical axis A 1 .
  • the half-ball forming the corrective portion 6, by slightly modifying the orientation of the rays emitted by the outputs of the guides which are offset with respect to the optical axis A 1 , at the output interface 61, has a corrective effect of
  • the device according to the invention makes it possible to dispense with relative positioning games between the guides associated with a Code function and a Route function, by the monobloc production of at least one series of these guides and of the corrective part associated with the all of these guides.
  • this correcting part 6 is particularly advantageous to associate this correcting part 6 with an arrangement of particular light guides in that two distinct types of guides are superimposed, arranged in particular differently with respect to the focal plane which is the object of the detection system.
  • the outputs of the first guides define the secondary images associated with these first guides and are positioned in the object focal surface SF of the projection system , so that the beams leaving the secondary optical projection element 4 and corresponding to the rays emitted by the first primary light sources, that is to say the sources corresponding to the upper part of the road beam, are beams parallel rays forming light segments of generally rectangular shape.
  • the second primary optical means is arranged with respect to the object focal surface SF of the projection system so that the curve which bears the transverse ends of each of the patterns formed in series on the input face of the first guide is defocused, in upstream of this focal object surface.
  • the light module of the invention has excellent optical efficiency.
  • the luminous flux emitted by the primary light sources undergo little loss in the corrective part and they are largely recovered at the output of the module to create light beams capable of forming light segments on the one hand for the complementary road beam and an overall wide beam for the code beam.
  • the light module can produce, with simple means and a corrective part common to the primary light sources, light segments for the additional road beam, the shapes of which are perfectly controlled and a Code beam made horizontally homogeneous by the defocusing of the strip of continuous material allowing the rays to be spread in the corrective part.
  • Patterns of the “modulations” or “microstructures” type could be added to the surfaces of the secondary optical element 4 to deliberately add a controlled cutoff blur.
  • a primary optical element carrying stepped light guides capable of being opposite series of distinct primary light sources makes it possible with a single means to achieve a plurality of optical functions, including in particular a so-called DBL function.
  • DBL Dynamic Bending Light in English for mobile bending lighting
  • AWL Automatic Weather Light in English, for bad weather light
  • One and / or the other of these functions is easily carried out by modulating the light intensity emitted by the primary light sources opposite the light guides. For example, it is possible gradually, from right to left or from left to right depending on the direction of the turn detected, to increase the intensity of the light sources to increase the visibility on one side of the overall light beam and thus perform a function DBL. In the event of a rainy road, it is possible to reduce the light intensity of the second primary light sources which are close to the optical axis.
