  • the invention proposes a lighting or signaling device in which a particular output block of the device under consideration is constituted, said output block consisting of a stack of screens independent of each other; each screen comprises a plurality of optical patterns, made in its thickness, capable of deflecting light signals emitted by a light source of the device in question; the spread of the light beam at the output of the lighting or signaling device considered is thus adjustable in a first direction of diffusion, corresponding, for each screen considered, to a direction parallel to a plane defined by said screen and containing the optical patterns , and in a second direction of diffusion, corresponding to a direction parallel to a plane generally perpendicular to the planes defined by the screens, the spreading according to the second diffusion plane depending on the relative position of the different screens.
  • the invention therefore essentially relates to a lighting or signaling device for a motor vehicle, including in particular at least one light source emitting a light beam, consisting of a plurality of signals light, in the direction of an output block of the lighting or signaling device, characterized in that the output block comprises in particular a stack of screens, said stack consisting of at least a first screen and a second screen, each screen having an input face receiving the light signals and an output face, the input face and the output face of each screen being joined by an upper face and a lower face defining between them a thickness of screen, at least one of the screens comprising at least one optical pattern made in the thickness of the screen in question, consisting of a through cavity formed in the screen that includes it.
  • the present invention also relates to a screen of the stack of screens present in the lighting or signaling device having the main characteristics and possibly one or more secondary characteristics which have just been mentioned, said screen having a face d an input and an output face, the input face and the output face of each screen being joined by an upper face and a lower face defining a screen thickness, characterized in that the screen comprises at least one pattern optical made in the thickness of the screen considered.
  • the present invention also relates to a motor vehicle equipped with a lighting or signaling device comprising the main characteristics and possibly one or more additional features just mentioned.
  • FIG 1 an example of a screen or optical system 100 according to the invention, intended to be positioned at an output block of a lighting or signaling device, in particular a motor vehicle, is shown.
  • the screen 100 is made of a transparent material, ie a material that can be traversed by the light; in a particular example, the material used is polymethylmethacrylate (PMMA) or special polycarbonate (PC) guide.
  • PMMA polymethylmethacrylate
  • PC special polycarbonate
  • the screen 100 has a plate shape, with an input face 101 for receiving light signals 200, visible to the figure 2 , an exit face 102, visible from the outside of the lighting or signaling device in which the screen 100 is intended to be positioned, an upper face 103 and a lower face not visible in the figures.
  • two screens 100 are of the same shape if they are identical in terms of dimensions and relative positions of the four faces that have just been mentioned.
  • the measurement of the distance between the lower face and the upper face gives the thickness of the screen 100.
  • the upper face and the lower face are flat and parallel, thus giving the screen a plate shape. They could also be regulated surfaces, that is to say generated by a line that moves according to a predetermined law. They could also be flat and not be parallel to each other, and thus form an angle between them.
  • the embodiment with flat surfaces, or set according to the same law, is a particularly advantageous feature during a stacking operation of the screens 100, stacking which will be detailed later.
  • the input face 101 and the exit face 102 are curved, their radius of curvature being infinite, the input faces 101 and output 102 then having a generator for a straight line.
  • the term "curve” qualifies lines, rows or surfaces whose radius may tend towards infinity, the rows or rows then being straight lines and the surfaces of the planes.
  • the curves defined by the sections of these input faces and emerging in a longitudinal or transverse plane are not necessarily parallel. Their shape is determined primarily by the function of the device they equip, and by the position of said device on the vehicle considered.
  • each optical pattern 104 consists of a through cavity, which creates a hole in the thickness of the screen 100, thus constituting dioptres.
  • the optical patterns are here arranged in a first curved row 105 and in a second curved row 106, parallel to the input face 101, the first curved row 105 being the row closest to said input face.
  • the first curved row 105 consists of convergent type optical patterns 107, whereas the second curved row 106 consists of divergent or convergent optical patterns 108.
  • the figure 2 shows a second example of a screen or optical system 100 ', seen from above, ie by positioning itself above the upper face 103.
  • the input faces 101' and the output faces 102 are straight, aligned with an axis OY, essentially for the sake of simplification of the figure.
  • the input face 101 ' receives a plurality of light signals 200, which are derived from a light beam emitted by at least one light source, not shown, of the lighting or signaling device according to the invention.
  • the light source may be of conventional type, that is to say a halogen or xenon lamp, or light emitting diode type.
  • the light beams reach the input face 101 'in the form of a parallel beam, all of these light signals being parallel to each other; the light signals reach the input face 101 while being perpendicular to the latter; the light signals reaching the input face 101 being perpendicular to the latter constitute a light plane.
  • the light signals are here oriented along an axis OX, an axis OZ directed upwards and perpendicular to the upper face 103 completing the two other axes which have just been cited to form an orthogonal reference (OX, OY, OZ).
  • the axis OZ is vertical.

Fresnel, directly made on the input face 101 or 101 'of the optical system 100 or 100'.
  • This Fresnel system may consist of a conventional Fresnel lens, preferably of revolution around the emission axis of the light source used. It may also consist of a Fresnel cylindrical lens, preferably linear to simplify manufacture, and in particular demolding. In the latter case, the beam is collimated only in the plane parallel to the screen constituting the optical system 100 or 100 '.
  • optical patterns 104 contained in the material of the screens according to the invention ensures the return of a portion of the light, for example sunlight, which would penetrate into the device. lighting or signaling by the exit face of the screen in question, thus giving a glittering appearance to the device under consideration, even when the light source that it comprises is not lit and also masks the actual sources to the origin of the beams, thus improving the homogeneity of the lit system.
  • the figure 3-A shows a first example of stacking, according to the OZ axis, optical systems or screens having the same shape as the screen 100.
  • the input faces 101 of each screen 100 are aligned, the exit faces 102 of each screen 100 are curved, so that the stack 300 has an overall exit face 301 consisting of the juxtaposition of the exit faces 102 of each screen 100, continuously rounded, the face of global output 301 having no discontinuities or inflection zones.
  • a distribution 302 of the output light beam is obtained with a main convergence point 303 of the output light beam.
  • a distribution 305 of the output light beam is obtained, with as many points of convergence 306 of the overall output beam that there are screens 100 ', five in this case.
  • the points of convergence 306 are aligned in a direction parallel to the input faces 101 '; they are thus contained in a vertical plane.
  • the figure 4-A shows an example of stack 400 in which the screens 100 are progressively offset along the axis OX.

  • the convergence points 402 are aligned in a direction parallel to the entry face 101, they are thus contained in an oblique plane.
  • the figure 5-A shows an example of stack 500, respectively 500 ', in which the screens 100 are arranged so as to have an overall output face 501, respectively 501', bump, respectively recessed.

It is also possible to ensure this connection via suitable mechanical systems.
