Definitions

  • the present invention relates to a motor vehicle headlamp device equipped with light emitting diodes.
  • the main purpose of the invention is to propose an alternative solution to the projectors devices using halogen-type or discharge-type light sources, which pose a number of problems in the production of the projectors devices.
  • the DBL, FBL, AWL, Town Light, Motorway Light and Overhead Light functions are grouped together as AFS functions.
  • the projector device according to the invention will be essentially described in use as crossing lights. It could nevertheless be used in any other projector device cited, or intervene in one of the mentioned functions. Describing the invention in the context of low beam is therefore in no way limiting to this application alone.
  • the first family is that of so-called elliptical projectors.
  • a spot of light concentration is generated by a light source arranged in a mirror.
  • the light source is disposed at the first focus of an ellipsoid-shaped mirror, said spot forming at the second focus of the mirror.
  • the spot of light concentration is then projected onto the road by a convergent lens, for example a plano-convex lens.
  • the second family is that of so-called reflection projectors with complex surface, or parabolic.
  • a light beam is generated by a small light source disposed in a reflector, or mirror.
  • the projection on the road of the light rays reflected by a suitable reflector makes it possible to directly obtain a light beam obeying the various constraints imposed by the standards.
  • This family of projectors includes so-called free-surface projectors, or complex surfaces, which make it possible to obtain directly a light beam having a desired cut-off line.
  • the device according to the invention relates more particularly to this family of projectors.
  • a parabolic projector device for example of the code-fire type, of the state of the art is schematically represented in FIG. figure 1 by a sectional view.
  • a code light 100 comprises, in a conventional manner, in a housing 105, essentially a reflector 101, a light source 102 emitting light rays 103, disposed in the vicinity of the focus of the reflector 101, and an output surface 104 of the beam
  • the luminous beam 106 is defined as a group of light rays that are actually emitted by a searchlight at the exit surface 104, the volume illuminated by the light beam corresponding to the driver's viewing zone; by light rays means all the light signals emitted by the light source 102.
  • the light rays 103 are emitted either directly to the exit surface 104 , or indirectly after suffering any deviations and / or reflections.
  • the figure 2 shows the reflector 101 seen from the front.
  • the reflector 101 is virtually divided into several distinct zones, each of the zones making a contribution rigorously defined in the constitution of the light beam 106 emitted by the projector.
  • a projection 300, on a plane, of this light beam is shown in FIG. figure 3 .
  • the light projection 300 is bounded horizontally by a cut line 306.
  • the light projection 300 is artificially cut into distinct regions.
  • a first region 301 and a second region 302 constitute the so-called range regions of the light beam. It is in these areas that the intensity of the beam must be maximum. It must provide a satisfactory visibility in the axis at 70 meters.
  • a third region 303 and a fourth region 304 constitute the so-called comfort regions. They provide a satisfactory visibility at about 40 meters.
  • a fifth region 305 constitutes the so-called width region. It makes it possible to obtain visibility downwards, that is by lighting up the bitumen, which is satisfactory at about 30 meters.
  • the light source 102 of the projector device contributes to each of the regions just mentioned by reflecting on the reflector 101 differently depending on the reflection zones where the image of the light source 101 is formed.
  • the first bearing region 301 and the second bearing region 302 of the light beam consist essentially of images of the light source reflecting respectively in a first zone 201 and in a second zone 202 of the reflective surface of the reflector 101
  • These two zones are approximately horizontal, that is to say disposed in the vicinity of a central and horizontal plane of the projector device; indeed, the images of the light source 102 in these areas must be substantially horizontal to be disposed just below the cutoff line 306 of the light projection 300; and, in view of the generally cylindrical shape of the halogen lamp or discharge lamp type light sources, the length, disposed along the projection axis of the projector, being much smaller than the width, it is much easier to make coincide correctly these images below the cut line when they are horizontal, so less spread out in height than vertical images.
  • This constraint which imposes a type of shape for the reflect
  • first comfort region 303 and the second comfort region 304 of the light beam essentially consist of images of the light source reflecting respectively in a third zone 203 and in a fourth zone 204 of the reflective surface of the reflector 101.
  • region of width 305 of the light beam consists essentially of images of the light source reflecting in a fifth zone 205 of the reflective surface of the reflector 101.
  • a first problem encountered with this type of projector of the state of the art is that a significant part of the light radiated by the light source is lost: in fact, the light sources used have an omnidirectional radiation, that is to say diffused in all directions of space. Due to the shape of the projectors, more particularly the presence of cheeks which limit the height of the reflectors, part of the light rays emitted by the source is not used in the beam.
  • a second problem encountered with the projectors of the state of the art is their size: indeed, as we have seen above, the shape of the complex surface is mathematically defined to create, from a single light source, the light beam as a whole.
  • the complex surface is formed of a single piece, and therefore voluminous, because it can not be split into several elements.
  • a third problem with these projectors is that they consume a lot of energy.
  • a fourth problem is that these light sources are particularly exothermic, and it is necessary to provide in the projectors different devices for removing heat.
  • a last problem is related to the unicity of the light source: when it no longer works, it is the entire beam of light produced by the projector is lacking.
  • the invention therefore essentially relates to a projector device, intended to emit at least one type of light beam, comprising at least one light source and at least one reflecting surface for reflecting light rays produced by the light source, characterized in that the light source comprises at least one element of the electroluminescent diode type.
  • the two variants can be combined, having in the same projector at the same time diodes separated from each other and assembled diodes assimilable to a single conventional source.
  • Another object of the invention is a motor vehicle equipped with at least one projector device having at least one of the characteristics that have just been specified.
  • the figure 4 is a front view of a reflector 400, intended to be used in a projector according to the invention, whose overall shape is very close to that of the reflectors of the state of the art.
  • the light source consists of a plurality, eight in the example shown, of light-emitting diodes 401 which are arranged in a star around a central position 402 of the reflector 400.
  • the eight diodes 400 are regularly spaced around the central portion 402.
  • each diode participating in the constitution of a light beam is associated bijectively with a particular area of the reflecting surface used to obtain the desired light beam. So, on the figure 4 , each of the eight diodes is dedicated to a specific area 403, which is reserved for it, of the reflecting surface, the different areas being symbolically delimited by a solid line.
  • the use of the diodes 401 implies on the one hand the multiplicity of these diodes for producing a projector device producing light beams identical to those of the state of the art, and on the other hand an increase in the specific surface area dedicated to regions of high intensity of the light beam.
  • the zones dedicated to the diodes which bring more particularly their contribution to the regions of range of the light beam.
  • each reflection zone is constructed as a complex surface whose calculations are carried out so that it contributes appropriately to the production of the light bleam.
  • Another possible example of arrangement of light emitting diodes 400 is a so-called barrel arrangement.
  • this arrangement there is always a set of light-emitting diodes around the central portion 402, but as tightly as possible so that the total luminous flux produced is comparable to that of a halogen lamp or Xenon usually used, in particular in terms of omnidirectionality of the luminous flux produced.
  • the reflection zones reserved for the light beam bearing regions are not necessarily the horizontal zones, ie the areas disposed in the vicinity of a horizontal and central plane of the projector device.
  • This absence of constraint leaves a great diversity of choices in the distribution, on the reflecting surface 400, of the role of the different reflection zones.
  • the emitting surface of the diodes may not be strictly square, it may have more varied geometric shapes (rectangle, triangle ...), its specificity being to be generally a substantially flat surface.
