Definitions

  • the present invention relates to a projector of the elliptical type for a motor vehicle.
  • the present invention more particularly relates to a motor vehicle headlamp, comprising a light source, an elliptical reflector whose first focus is located in the vicinity of the source, a convergent lens having a focal plane passes in the vicinity of a second focus of the reflector, and an occultation screen which is interposed axially, along the longitudinal optical axis of the projector, between the reflector and the lens, and which delimits a cutoff profile in the light beam emitted by the source to produce a beam Rainy day lighting regulation with an area of less illumination below the cut-off.
  • the blackout screen constitutes a diaphragm whose edge forms the cutoff profile which is reproduced towards infinity, at the front of the vehicle, by the objective formed here by the lens, to form a lighting beam having a cut whose shape corresponds to the cutoff profile.
  • the diaphragm reproduced by the lens makes it possible to obtain a darkness / clarity limit whose shape is perfectly defined according to the needs, with a sharpness or a desired blur.
  • the regulatory beam for rainy weather lighting has the particularity of having a cut-off profile identical to that of a regulatory crossing beam and of having a zone of lower illumination which is situated below the cut-off, inside. of the lighting beam.
  • the regulation imposes a weakening of the illumination below the cutoff profile and to the left of the longitudinal axis of the vehicle, in the case of a traffic on the right of the roadway.
  • the zone of less illumination is intended to prevent drivers traveling on the opposite lane from being dazzled by the reflection of the light rays on the left side of the roadway between the two vehicles traveling in opposite directions, due to the wet condition of the vehicle. floor.
  • the elliptical projector is generally intended to produce several regulatory lighting beams, in particular a conventional passing beam, since the lighting beam in rainy weather only corresponds to a particular traffic situation.
  • the elliptical headlamp is provided with at least one movable occultation screen at several positions corresponding to several regulatory lighting beams, including the lighting beam in rainy weather.
  • an occultation screen tilting about a horizontal transverse axis between a concealment position and a retracted position.
  • This screen has a cutoff profile corresponding to a regulatory crossing beam and a transverse tab which is intended to form the area of lower illumination corresponding to the lighting beam in rainy weather.
  • the occultation screen is movable between an active position in which the screen obscures part of the light rays emitted by the source so that the projector realizes a regulation light beam in rainy weather, and a retracted position in which the projector achieves another regulatory lighting beam.
  • the tab is attached to the front of the screen and extends vertically upward. Therefore, it forms, in the lighting beam, a zone of less illumination that extends to the cut.
  • the lighting beam obtained is not entirely satisfactory because the tongue deteriorates the quality of the lighting beam near the cut.
  • defocused tab creates an imbalance on the mobile screen.
  • the presence of this unbalance is particularly troublesome in a projector comprising a drum mounted to rotate about an axis inclined in the longitudinal plane, such as the conical drum which is described in the document FR-A-2815310 .
  • the unbalance effect produced by the defocused tab on the pivoting part can be a source of vibration in the projector and it can cause premature wear of the motor that drives the drum.
  • the presence of the defocused tab may cause congestion problems inside the projector, including mechanical interference, depending on the different angular positions occupied by the blackout screen.
  • the invention aims to remedy these drawbacks by proposing a simple, effective and economical solution.
