Definitions

  • the present invention relates to a projector of the type elliptical for a motor vehicle.
  • the present invention relates more particularly to a motor vehicle headlamp, comprising a source luminous, an elliptical reflector of which a first focus is located near the source, a convergent lens a focal plane passes near a second focus of the reflector, and an occultation screen which is interposed axially, following the longitudinal optical axis of the headlamp, between the reflector and lens, and which delimits a cutoff profile in the beam light emitted by the source in order to create a beam regulation of rainy weather lighting including a area of lower illumination which is located below the cut.
  • the blackout screen constitutes a diaphragm whose edge forms the cutoff profile that is reproduced towards infinity, at the front of the vehicle, by the objective formed here through the lens, to form a lighting beam comprising a cut whose shape corresponds to the cutoff profile.
  • the diaphragm reproduced by the lens allows to obtain a limit darkness / clarity whose form is perfectly defined in according to the needs, with a sharpness or a desired blur.
  • Regulatory beam of rainy weather lighting has the particularity of having a cutoff profile identical to that of a regulatory beam of crossing and have a zone of less illumination which is located below of the cut, inside the lighting beam.
  • the regulation imposes a weakening of the illumination below the profile cut-off and to the left of the longitudinal axis of the vehicle, in the case of a traffic on the right of the roadway.
  • the area of least illumination is intended to prevent the drivers traveling on the opposite lane are dazzled by the reflection of light rays on the left side of the roadway between the two vehicles traveling in opposite directions, in because of the wet condition of the roadway.
  • the elliptical projector is usually planned to make several regulatory lighting beams, in particular a conventional passing beam, since the lighting beam in rainy weather is only one special situation of circulation.

  • This screen has a cutoff profile corresponding to a beam crossing regulation and a transverse tongue which is intended to form the area of least illumination corresponding to the lighting beam in rainy weather.
  • the tab is attached to the front of the screen and it extends vertically upward. Therefore, she trains, in the lighting beam, a zone of less illumination which extends to the break.
  • the lighting beam obtained is not entirely satisfactory because the tongue deteriorates the beam quality lighting near the cut.
  • defocused tab creates an unbalance on the mobile screen.
  • the presence of this unbalance is particularly troublesome in a projector having a drum rotatably mounted about an inclined axis in the longitudinal plane, such as the conical drum which is described in FR-A-2.815.310.
  • the unbalance effect produced by the tongue defocused on the pivoting part can be a source of vibrations in the projector and it may cause wear premature engine that drives the drum.
  • the presence of the defocused tab can have space problems inside the projector, and in particular mechanical interference, depending on the different angular positions occupied by the screen occultation.
  • the aim of the invention is to remedy these drawbacks by offering a simple, effective and economical solution.
  • the invention proposes a projector of the type previously described, characterized in that the blackout screen has at least one generally transverse portion which is made of transparent material and which extends over the cutoff profile, and in that this transparent portion of the blanking screen has a zone of less transparency which forms the zone of least illumination in the beam regulatory lighting.

  • the upper edge 44 of the occulting portion 36 draws the two cutoff profiles 32, 34 of the illumination beams Fp, Fc associated with the screen 30.
  • Part of the occulting portion 36 extends here under height of the upper edge of the cutout 29 of the mask 20, way that no light ray can reach the lens 18 passing between the upper edge of the cutout 29 and the edge bottom of the occulting portion 36.
  • the upper portion 38 of the occultation screen 30 extends globally vertically to the top of the focal zone useful, with respect to the lens 18, so that all the rays luminous which serve to construct the projected lighting beam by the lens 18 pass through the transparent upper portion 38.
  • the occultation screen 30 can be divided geometrically into two angular sectors 46, 48, relative to the pivot axis A2, which are substantially of the same circumferential dimension.
  • a first angular sector 46 has the profile of cutoff 32 corresponding to the rain beam Fp and a second angular sector 48 has the cutoff profile 34 corresponding to the passing beam Fc.

  • the density of opaque material present in the zone of lesser transparency 50 must therefore be less than density of opaque material arranged in the occulting portion 36.
  • the area of less transparency 50 creates in the rain beam Fp a zone Z1 having illumination of intensity less than the illumination adjacent areas, without producing a gray area extending until the break.
  • the second angular sector 48 of the occultation screen 30 has a cutoff profile 34 corresponding to a beam of crossing Fc. Unlike the first angular sector 46, it is therefore devoid of a zone of less transparency.

  • Such a type of material 30 allows in particular to minimize the mass of the occultation screen 30, so reduce its inertia, and it helps reduce light loss by glassy reflection, because of the low refractive index of this material.
  • the inclination of the pivot axis A2 limits the size of the screen occultation 30 in the projector 10. Moreover, thanks to this inclination, the angular sector 46, 48 which occupies its position retracted is lower than the angular sector 46, 48 which occupies its active position, so that the angular sector 46, 48 retracted is under the path of the light rays forming the lighting beam Fp, Fc.
  • the invention has been described with an occultation screen 30 having two cut profiles 32, 34.
  • the invention also applies to a projector 10 equipped with a screen occultation 30 having a single cutoff profile, or more than two cutoff profiles.
