Definitions

  • the present invention relates to motor vehicle headlamps of type comprising a filter opaque to visible radiation but transparent to infrared.
  • Document FR-A-2 756 237 discloses such projectors which are furthermore arranged to allow the filter to move between an active position and a retracted position. These projectors have a large surface on the front face.
  • the object of the present invention is to solve this drawback, that is to say to propose a projector having such a mobile infrared filter but which has a small surface on the front face.
  • a motor vehicle headlamp comprising a light source, a reflector with two focal regions, the source being placed in one of the two focal regions so as to produce a reflected light spot in the another focal region, and a filter opaque to visible radiation and transparent to infrared radiation, movable between a position away from the reflected reflector light and a position where it is traversed by a substantial portion of the light reflected by the reflector to the lens, characterized in that it comprises a lens designed to transform the task of reflected light into a beam projected onto the road, the lens being placed in front of the reflector.
  • the general structure of the projectors shown in FIGS. 1 to 9 comprises a reflector 100 of ellipsoidal type, internal focus 110 and external focus 120, a lens 200 whose focus coincides with the external focus 120 of the reflector 100, and a source of light 105 placed on the internal focus 110 of the reflector 100.
  • the surfaces of ellipsoidal genus are usually surfaces defined mathematically respectively from two focal zones, which are here called the foci 110 and 120, but which in practice have a slight extent. This range encompasses the filament of the source in the case of the internal focal zone 105, and forms a light spot in the case of the external focal zone 120.
  • the mathematically defined surface is therefore substantially close to an ellipsoid.
  • the rays emitted by the source, after reflection on the ellipsoidal reflector 100 cross in the vicinity of the external focus 120.
  • the light rays arriving on the lens 200 therefore appear emitted by a small source placed on the focus 120.
  • the rays are then projected in front of the vehicle forming an appropriate light distribution beam suitable for the "road" function.
  • a small movable filter 300 is in the active position, positioned in the vicinity of the external focus 120 of the reflector 100, so that it intercepts the radiation almost luminous as a whole, due to the concentration of the rays at this location.
  • the filter 300 here placed downstream of the external focus 120, may be arranged upstream or exactly on the external focus 120 relative to the path of the light rays.
  • the filter 300 thus placed intercepts almost all the light that propagates from the reflector 100 to the lens 200, while being placed in a zone of large volume relative to the size of the filter. It is thus possible to easily place improved holding and moving means in this area.
  • the positioning of the filter in the vicinity of the external hearth 120 further allows positions of the filter 300 which are close to the active position and which do not interfere with any radiation, which can therefore be adopted as inactive position of filter 300.
  • the filter 300 is here formed by a small square-shaped plate. It is placed perpendicular to the main axis of projection.
  • FIG. 1 A first embodiment of this device is illustrated in Figures 1 and 2, wherein the filter 300 is movable in a vertical translation y direction.
  • the filter 300 can be guided on a rail 400 symbolized in the figure by a broken line axis and can be driven for example by an electric motor or an electromagnet.
  • the filter 300 is preferably housed in a frame made of a flexible material, for example sheet metal, this frame being deformed under the effect of the expansions of the filter, without breaking the filter.
  • the filter 300 is maintained by means of elastic return means that extend or fold under the effect of the expansions of the filter 300.
  • the translation of the filter can be done in a horizontal Z direction, also transverse to the main direction of propagation.
  • the filter 300 is mounted in translation on a rail parallel to the main direction of propagation.
  • the filter 300 In the erased position, the filter 300 is sufficiently distant in front of the external focus 120, to interfere with very little light.
  • elliptical projectors typically have a shadow cone 150 corresponding to the bottom hole of the reflector in which the lamp is held. This hole, occupied by the base of the lamp, non-reflective assembly, is the cause of a virtual absence of light ray in this cone which typically surrounds the main axis of propagation.
  • This cone 150 generally has a small angular aperture. However, since the dimensions of the filter 300 thus disposed are particularly small, the filter 300 is housed almost completely within this cone 150 by simply moving the filter towards the opening direction of the cone 150.
  • the filter 100 is rotatable about a horizontal axis.
  • the y1 axis is transverse to the direction of propagation of the light above the light flux.
  • the axis of rotation y1 simply follows a border of the filter so that it disappears on the side of the radiation, particularly concentrated in the vicinity of the focus 120.
  • FIG. 7 the path of light between the second focus 120 and the lens 200 is shown.
  • the light here describes a cone 250 whose tip is on the second focus 120, and the base on the periphery of the 200.
  • the y2 axis is placed sufficiently in front of the active position of the filter 300 so that a rotation of about 60 ° is enough to cause the filter 300 to come out of the light cone 250.
  • the axis y2 is however sufficiently close to the filter 300 for the filter 300 to come close to the cone 250, parallel to its conical envelope.
  • the axis of rotation y3 is placed vertically and offset towards the front of the active position of the filter.
  • the displacement means of the filter cause a 180 ° rotation of the latter, so that the filter, when retracted, undergoes not only a rotation, but also a forward shift, until it is placed in the cone of the filter. shadow 150 previously cited.
  • the axis y3 and for example placed transversely to the center of the radiation, at the intersection with the main beam of the projector.
  • the filter just seems to have been translated.
  • the invention extends to any type of movement of the filter, that is to say using any degree of freedom, for example a rotation along any one of three main axes of rotation and / or a translation according to the invention. any of these three axes.
  • FIG. 9 there is shown a filter 300 placed slightly downstream of the external focal zone 120.
  • the filter 300 has a range and a positioning such that it does not intercept all of the light. A portion of the rays reaches the lens 200 passing outside the edges of the filter 300. These rays join the lens 200 at the periphery thereof.
  • a lens 300 is adopted in this annular peripheral zone of the lens 300. clean layout to accentuate the diffusion of light, that is to say to disorganize the rays (lantern effect).
  • the lens has for example in this area a frosted glass or a light graining.
  • a frosted glass or a light graining is for example in this area.
  • the diffusion of white leakage at the periphery of the lens produces a lateral photometry of the "lantern" type which provides a white appearance to projectors, with, however, preferentially a high intensity in the axis to allow a sustained signaling close to the maximum authorized for a lantern (60 candela) or "Day Running Light" type.
