This results in a light source that has variable luminance along the direction of the optical axis.
  • each of the electroluminescent elements so that the first set 81 of rods has a higher luminance of 3 to 4 times the average luminance of the other sets of rods.
  • pilot elements associated with the light source 2 are configured to control the activation of the first set 81 distinctly from that of the second 82 and / or third 83 together.
  • the elliptical reflector has a first focus on which is positioned the light source, and more particularly the longitudinal end edge corresponding to the first set of rods, and a second focus coincides with the object focus of the diverging lens.
  • This matching point of the second focus of the reflector and the focus of the diverging lens is located on the other side of the diverging lens with respect to the light source and the reflector.
  • the diverging lens is positioned between the first and second focus of the reflector.
  • First rays (represented on the figure 1 by single-arrow lines) are emitted from the first set 81 of rods 8, that is to say from the zone of the light source substantially located on the first focus of the reflector. This results in a deviation of the rays emitted towards the second focus of the reflector, the latter being elliptical or at least configured so as to respect this principle of elliptical reflection with a double focus. These rays, before reaching the second focus of the reflector, arrive on the diverging lens.
  • Second rays (represented on the figure 1 by double-headed lines) are emitted from the second or third set of rods 8, corresponding to an area of the light source located downstream of the first focus of the reflector, ie located between the first focus and the second focus of the reflector. This results in deviated rays which would be caused to cut the optical axis upstream of the second focal point of the reflector, in the absence of a lens, as also illustrated on FIG. figure 2 . These rays, before reaching this theoretical point of focus, arrive on the divergent lens.
  • the reflector is adapted to project the image of the very bright part of the source opposite the divergent lens, in the vicinity of the object focus of the diverging lens, so that the corresponding rays emerge parallel to the optical axis by forming the cutoff of the beam emitted at the output of the diverging lens.
  • the highest luminance is obtained by a greater mean height of the rods 8 of this first set 81, but it will be understood that that this high luminance could be obtained differently, by a greater density of rods for example.
  • an area of high luminance is arranged on the rear longitudinal end edge 80 of the light source 2, that is to say the edge of the light source opposite to the diverging lens. As has been previously stated, this edge having an area of high luminance is disposed on the first focus of the elliptical or pseudo-elliptical reflector.
  • the first set 81 of rods of high luminance and disposed in the direct vicinity of the rear longitudinal end edge 80, generates a first part 101 of the projected beam, more intense, and successively, each set of rods, the luminance decreases in s away from the first set 81 of rods, generates a portion of less and less intense beam, and intersecting the optical axis upstream of the second focus theoretical F2, so that they are caused to be projected under the horizon, closer and closer to the vehicle, when corrected by the shaping optics 6 and in particular the diverging lens.
  • driving elements associated with the light source control the selective activation of the electroluminescent rods present in each of the rod sets.
  • the driving of these assemblies can be selective in that the power intensity of each of the sets of rods varies according to their distance from the longitudinal end edge 80 of the light source 2.
  • a fire-type beam is formed here. crossing, with a cutting edge, it being understood that other types of beam could be made, in particular by modifying the position of the light source with respect to the first focus of the reflector.
  • the present invention is particularly applicable to a front projector of a motor vehicle, and it integrates in particular in a vehicle front face.
  • the embodiments apply to light sources comprising both electroluminescent rods respectively projecting from the same substrate, as described above, with emitting blocks obtained by cutting electroluminescent layers. superimposed on the same substrate, these blocks replacing the rods.
  • the structure of the light device which has just been described by way of non-limiting example, since it uses at least one light source comprising a plurality of light sources.
  • electroluminescent elements for example an elliptical or pseudo-elliptical reflector, and a diverging lens.
  • the invention can not be limited to the embodiment specifically described in this document, and extends in particular to all equivalent means and any technically operating combination of these means.
