Definitions

  • An optical module of this type known from FR-A-2,840,389 , makes it possible to make a secondary infrared lighting beam in an area above the cutoff, using a diffuser fixed on the front face of the cover.
  • the illumination range of the secondary beam is located substantially above the optical axis and is off-center with respect to this axis.
  • the illumination grid that is to say the area illuminated on a screen situated at a predetermined distance from the spotlight and orthogonal to the optical axis, must be rectangular , centered on the optical axis between defined limits.
  • the object of the invention is, above all, to provide a luminous headlamp, with a main beam of cut-off lighting, which makes it possible to ensure at least one additional secondary function of the city lamp or DRL type, without interfering with the main function.
  • an optical module of the kind defined above comprises a retractable return mirror that can pass from a retracted position, where the mirror does not substantially interfere with the beam principle, at a working position in which the reflecting mirror is in the vicinity of the focal plane of the lens, substantially centered on the optical axis and oriented so as to give, from the light rays issuing from the secondary source, a secondary beam, preferably substantially centered on the optical axis, and constituting the secondary function of illumination.
  • the light rays "derived" from the secondary source can reach the reflecting mirror directly and / or indirectly (that is to say having possibly previously undergone at least one modification of their initial trajectory, for example by at least one prior reflection on another reflective surface.)
  • this beam conforms to a substantially rectangular illumination grid
  • the reflecting mirror may be substantially flat, in particular rectangular.
  • the long side of the reflecting mirror can be substantially horizontal.
  • the projector's cover is fixed and the reflecting mirror, in its working position, is in front of the cover.
  • the cover is movably mounted, in translation or in rotation, and is erased to allow the introduction of the deflection mirror in the working position.
  • the cover is movably mounted makes it possible to confer on the optical module several so-called main functions with the same light source: it is possible to provide a cover, which, in the retracted / retracted position, makes it possible to obtain a beam-type unbroken beam. and which, in working position, makes it possible to obtain at least one code-beam, fog-beam or other cut-off beam defined by the new functions AFS for the abbreviation Advanced Front Systems.
  • FR 04/06273 filed on 09/06/04 with a cache having an "active" edge composed of a set of distinct portions, at least a portion of one of the portions of the set of portions involved in the production of at least two different cuts of the light beam emitted by said light source, or the EP 1 197 387 .
  • the main source can generate a road-type beam with the cover in position and the reflecting mirror in both retracted positions (that is to say both inactive vis-à-vis the light rays emitted by the main source).
  • the reflecting mirror can then be placed in front of the cache or be integrated therewith.
  • the module according to the invention is therefore able to emit at least one cut-off main beam, in particular chosen from the code and fog beams. It is also capable of generating another main beam with or without cutoff, in particular of the road beam type.
  • the secondary function is preferably a city lamp and / or DRL function.
  • the secondary source may be located in the vertical plane passing through the optical axis and be spaced transversely of this axis; the reflecting mirror, in its working position, is inclined towards the secondary source with respect to the optical axis.
  • the secondary source can be supplied in a variable way: one can have a power supply which varies according to whether one wants a function of the type DRL (maximum power) or a city lamp function (reduced power): the source can thus make it possible to 'get two different functions by itself depending on how it is powered (under voltage or not).
  • the angle of inclination is such that the image of the secondary source given by the reflecting mirror is directed towards the lens. It may be on the optical axis or in the vicinity of this optical axis, but it is not a necessary condition.
  • the center of the deflection mirror is advantageously in the vicinity of the focus of the lens.
  • the secondary source can be oriented so as to directly illuminate the reflecting mirror including to provide a secondary function city lamp, while the main source is off.
  • the secondary source is advantageously oriented so as to illuminate opposite the reflecting mirror, to a fixed concave recuperating mirror which reflects and concentrates the light on the reflecting mirror.
  • the secondary source has a flow sufficient to provide a secondary function DRL, it is possible to provide another secondary function city lamp by a sub-voltage supply of the secondary source.
  • the deflection mirror may be rotatably mounted about an axis orthogonal to the plane passing through the optical axis and the center of the secondary source, and discarded transversely of the optical axis.
  • the cache can be mounted movably, in which case the reflecting mirror can be secured to the cache.
  • the cover can move from an active position corresponding to the main function with retraction of the deflection mirror, to an inactive position corresponding to the secondary function with reflecting mirror in working position, and vice versa.
  • the invention also relates to any projector incorporating an optical module previously described.
  • a light optical module P for a motor vehicle provided to give at least one main beam cut-off lighting.
  • a cut-off beam it is possible to indicate the code beam which generally comprises a horizontal part of the side where the vehicles cross each other, and an oblique part rising on the opposite side, or a horizontally cut fog lamp beam.
  • the optical module P shown schematically without its housing, has an optical axis XX and comprises an elliptical-type reflector R with an internal focus Fi and an external focus Fe on the optical axis.
