Definitions

  • the present invention relates to a motor vehicle headlamp device comprising essentially a mirror and a conjugate deflection element whose design is such that it produces a light beam whose cut is not flat.
  • the object of the invention is essentially to propose an improvement in an existing projector device, this improvement consisting in the introduction of modifications of the surfaces of the mirror and / or of the deflection element so as to obtain a non-flat cut of the light beam. product.
  • the projector device initially designed as an anti-fog, can thus be used in particular as a code-type projector device.
  • the projector device according to the invention finds its application mainly in use as dipped beam, because it fully meets the standards for this type of lights. It could nevertheless be used in any other projector device mentioned that would know normative evolutions. 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 parabolic projectors.
  • 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.
  • Such a projector device may optionally be supplemented by an ice-type exit surface, which may be provided for example with ridges for modifying the light beam, for example by spreading it in width.
  • 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 or cut-line.
  • cut line is meant the boundary between a low area illuminated by the projector device and a high area that is not illuminated by the projector device.
  • This type of projectors is particularly efficient in terms of reduced depth and light distribution.
  • One of the difficulties encountered in their realization is that it is necessary for their mirror to recover a large proportion of the light signals produced by the light source, otherwise it will produce an insufficiently intense light beam.
  • the first solution is to use a very small basic focal distance, in order to obtain a very closed mirror around the light source and not bulky in width; but because of the size - important in this case - images of the light source generated by the mirror, the light beam is then too thick, and therefore difficult to control.
  • the second solution is to increase the basic focal distance, but the mirror then has significant dimensions transverse to the optical axis, the projector device is then no longer compact.
  • the second 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 a mirror shaped ellipsoid of revolution, 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 light concentration spot is partially obscured, for example by means of a metal cover disposed within the projector device.
  • This type of projector is particularly efficient in terms of recovery of the light signals emitted by the light source; its dimensions transverse to the optical axis are also relatively small, which is also an advantage.
  • this type of projector has a large footprint in depth, and photometry is difficult to control because no corrective element having streaks can correct the light beam from the lens.
  • EP-1225386 a projector that attempts to meet the criteria outlined above.
  • This projector in addition to a reflector and a light source, comprises a concave or convex lens in vertical or transverse section. The light passing through the lens is refracted significantly and it is therefore difficult to see the interior of the projector.
  • a particular projector device has recently been proposed, which will be referred to as a basic hybrid projector.
  • the basic hybrid projector while technically belonging to the family of parabolic projectors - it does not have a cache to create a cut - present, off, an outer appearance closer to the elliptical projectors than are the conventional parabolic floodlights.
  • the proposed basic hybrid projector device also produces a good quality light beam.
  • the principle of construction of the basic hybrid projector device is schematically represented, in an axial horizontal section, in FIG. 1. Only the construction of a lateral half of the basic hybrid projector is illustrated, while the other half can be constructed with the same teachings. , symmetrically or not.
  • O is at the geometric center of a light source 10
  • YY is the optical axis
  • XX is the horizontal axis transverse to the optical axis of the projector
  • ZZ is the vertical axis.
  • the projector device is essentially composed of a lamp housing the light source 10, a mirror 20 and a transparent optical deflection element 30, called here a lens, placed in front of the mirror 20.
  • the mirror 20 is able to cooperate with the light source 10 for generating a beam delimited by a cut line, and the deflection element 30 is able to ensure a horizontal spread of the light, without substantially changing the vertical distribution of light.
  • the light beam produced by a projector device is constituted by a superposition of all the images of the light source after reflection of the light signals that it emits on the reflecting surface of the mirror 10 and after passing through the lens 30.
  • a generator 21 of which describes a curve y f 20 (x) which will be explained later.
  • the lens 30 is disposed transversely to the axis OY and has an inner face 31, or input face, receiving the light reflected by the mirror and an outer face 32, or output face, smooth, flat and perpendicular to the OY axis.
  • the lens 30 is obtained by moving a vertical director along this curve to form its inner face, the lens thus being cylindrical.
  • the mirror 20, respectively the inner face 31 of the lens 30, is manufactured according to a desired behavior in terms of propagation of the reflected rays, respectively refracted.
  • D / 2 denotes the half-width of the mirror 20 and of the lens 30.
  • the horizontal generator of the mirror 20 is constructed to satisfy a given law, an example of which is given in FIG. 2a, giving a dimension X (x), which is therefore a function of the abscissa x.
  • the horizontal generator 21 of the mirror 20 is progressively evolving, from the dimension x1, from an elliptical pace to a parabolic pace.
  • the lens which is represented in solid lines in its theoretical form with a square outline, is made with a circular outline 33 shown in dashed lines in FIG. 6.
  • the off-axis hybrid projector device presents, because of its smooth faces and because of its circular outline, a similar appearance and shape to a lens usually used in elliptical projectors devices.
  • the contour 23 of the mirror 20 is made so as to eliminate therefrom any zone capable of reflecting the light towards the outside of the circular contour 33 of the lens.
  • the hybrid projector device as just described is therefore a compact projector in width and depth, capable of generating a beam satisfactory in terms of intensity due to the small loss of light signals within the hybrid projector device, and having an appearance similar to that of an elliptical.
  • the images of the light source created by these turned parts thus producing a group of light rays, within the light beam produced by the projector device, which give rise to a cut which is no longer flat, and which can meet the standards regulating European and / or American codes.
  • the role of the lens 30 is to spread out horizontally the light rays that arrive on its inner face after reflection on the mirror 20. Turning a portion of the mirror 20 would therefore not cause a shift on the cut line, but a diffuse task over a large part of the width of the mirror. beam due to the horizontal spread caused by the lens.
  • the invention proposes a vertical tilting of certain surface areas of the mirror and / or of the lens, so that the inclination of these zones is modified, thus causing an upward shift of some of the images, constituting the light beam, of the light source.
  • the invention therefore essentially relates to a projector device comprising in particular a light source, a mirror having a reflective surface for reflecting light signals produced by the light source and comprising a horizontal generatrix moving from an elliptical pace to a parabolic pace, and an element transparent optical deflection having an input side of the reflected light signals and an output side of the reflected light signals, the transparent deflection element being placed in front of the mirror, the mirror being adapted to cooperate with the light source to generate a beam delimited by a cut line, and the deflection element being able to ensure a horizontal spread of the light signals produced by the light source and reflected by the mirror, without modifying the vertical distribution of the light signals, said projector device being characterized in that it comprises at least one recess provided on at least one of the surfaces encountered by the light signals to obtain a non-flat cutoff line of the light beam, the detachment consisting of at least one prism disposed on the transparent optical deflection element.
  • Another object of the invention is a motor vehicle equipped with at least one projector device having at least one of the characteristics which have just been described.
  • a new mirror 80 is obtained, a possible example of which is shown in FIGS. 8a (front view of the mirror) at 8c according to different views.
  • recesses are introduced on this surface.
  • the reflecting surface of the mirror 80 is a juxtaposition of a set of adjacent vertical strips, a recess here means a tilting of one of these vertical strips.
  • a left lateral vertical band 81 which corresponds to the left end of the reflecting surface of the mirror
  • a vertical band right lateral 82 which corresponds to the right end of the reflecting surface of the mirror
  • a central vertical strip 83 which corresponds to a strip adjacent to a vertical central axis 84 of the mirror.
  • the tilting of the lateral strips 81 and 82 makes it possible to obtain, in the light beam produced by the projector according to the invention, the recovery of small images of the light source disposed at the heart of the mirror, these images being of intensity quite important. This produces a rupture of the type of rupture 70 of FIG. 7a.
  • the tilting of the central band 83 makes it possible to obtain the recovery of larger images of the light source, but of lesser intensity, thus making it possible to obtain a cutoff line of the type of the cutoff line 71.
  • central side is located just to the left or just to the right of the central vertical axis 84 depending on the side where it is desired to go up the cut line 71.
  • the inclination of the strips lateral 81 and 82 is of the order of 3 degrees relative to the sidebands adjacent thereto, the inclination of the central strip 83 being of the order of 1 degree relative to the bands adjacent thereto.
  • the left lateral band between the abscissa -40 millimeters and -35 millimeters is available, the right lateral band between the abscissa 35 millimeters and 40 millimeters is arranged, and it is available the central band between abscissa -10 mm and 0 mm.
  • the tilting of the strips is preferably carried out so that connecting surfaces between the tilted strips and their adjacent strips are exposed as little as possible to the light rays produced by the light source, so as not to introduce too many parasites into the beam. light beam produced.
  • the prisms arranged on the extreme lateral strips of the exit face of the lens are intended to trace small intense images of the light source to create the rupture 70, the prism arranged on a central strip being intended to ensure the extension of this rupture by noting larger but less intense images of the light source.
  • a new mirror 90 is obtained, a possible example of which is shown in FIGS. 9a (front view of the mirror) and 9b in different views.
  • recesses are introduced on this surface. These recesses here consist in a replacement of a particular section 91 of the reflecting surface of the mirror 90, said particular section 91 corresponding to the lateral ends of a piece of mirror surface resulting from the intersection of the reflecting surface of the mirror and the space defined between a first central horizontal plane of the mirror and a second plane, inclined relative to the first plane, by a paraboloid-type surface.
  • Sections 101 may advantageously be portions of paraboloids (possibly different to the left and to the right) of foci placed on the axis of the filament and inside the filament. Parties' homes left and right are preferably merged centrally or shifted symmetrically. In all cases, in the back view, the right part has its focus in front of the center of the filament (towards the lens), and the left part has its focus behind the center of the filament (towards the mirror).
