Definitions

  • the invention relates to the field of lighting and / or signaling, especially for motor vehicles.
  • a motor vehicle is equipped with headlamps, or headlights, intended to illuminate the road in front of the vehicle, at night or in the case of reduced luminosity.
  • headlamps can generally be used in two lighting modes: a first mode “high beam” and a second mode “low beam”.
  • the "high beam” mode provides strong illumination of the road far ahead of the vehicle with a focused beam around the optical axis of these projectors.
  • the “dipped beam” mode provides illumination far away from the road, but nevertheless offers good visibility, without dazzling other road users, with a beam spread on both sides of the optical axis and under the light. skyline.
  • These two lighting modes are used alternately depending on the traffic conditions encountered by the vehicle, and they are successively implemented by a manual control of the vehicle or automatically by a suitable control device.
  • a first source is turned on and a cover cuts off part of the rays emitted to respect the shape of a first beam, of the cut-beam type, that is to say a partial beam illuminating the road scene as close as possible to the vehicle, with no rays emitted beyond the horizon line.
  • a Route beam it is necessary to switch on both sources simultaneously, so as to form the first beam as previously described via the first source and a complementary beam through the second source.
  • a disadvantage of such a solution is the presence of a dark bar between the first beam forming "low beam” and the complementary beam forming "high beam", the dark bar corresponding to the free end edge of the cache.
  • the overall beam formed by the superposition of the two half-beams is not continuous and this can generate discomfort for the driver.
  • the second light source must be sized to emit high intensity light rays. Particularly in the case of a second light source formed of light-emitting diodes, it is then appropriate to dedicate many of these diodes to the road function, while this function is implemented less often than the code function.
  • the present invention aims to propose a light module that provides a solution to these various disadvantages.
  • the invention aims at providing a light module for a motor vehicle comprising at least two light sources, a device for deflecting the light rays emitted by the light sources, an optical shaping of deviated rays, and an arranged cache. between the deflection device and the shaping optics and adapted to take at least two distinct positions.
  • the light sources are controlled according to the position of the cache.
  • the switching on or off of the light sources depends on the position of the cover, or that the luminous flux of these light sources changes according to this position of the light source. hidden. It is thus known, by a simultaneous control of these two components of the light module, to propose a single module configured to project two types of beams, without a dark bar being present in the beam in "driving beam" mode.
  • the invention also relates to a motor vehicle headlamp comprising a light module as just described above.
  • the invention furthermore relates to a lighting method of a motor vehicle, in which a first non-glare lighting function is performed, by projection of a cut-off beam, and a second long-range lighting function, by projecting a second unbroken beam, the passage from a cut-off beam to an unbroken beam being notably implemented by tilting a mask across the rays emitted by light sources, during which the pilot light intensity emitted by at least a first and a second light source according to the beam that is to be projected, the first light source being driven to emit at a higher intensity than the second light source when it is desired to produce a beam uninterrupted, while the first light source is driven to emit at a lower intensity than the second light source when it is desired to be a beam with cut.
  • the first light source is configured to emit rays spreading over the width of the beam emitted by the module
  • the second light source is configured to emit concentrated rays in the center of the beam emitted by the module
  • the lighting method may in this case be characterized in that the control of the first light source in reduction of light intensity is simultaneous with the increase in the intensity of the emission of the second light source, and simultaneous with the tilting of the cache in a position of partial shutter radii for the realization of a cut-off beam.
  • a control of the first light source in increase of light intensity can be simultaneous with the reduction of intensity of the emission of the second light source, and simultaneous with the tilting of the cover in a release position allowing passage to the all the rays for the realization of an unbroken beam.

It is understood that the emitted rays are thus deflected out of the light module 1 and participate in the formation of a lighting beam and / or signaling .
  • the light module is configured to be able to emit, as a function of the control of the light sources in particular, at least two types of light beams among which a beam of the "low beam” type and a beam of the "high beam” type ", Which differ from each other as well by the shape, respectively with or without interruption at the level of the horizon line, as by the luminous intensity, namely respectively a homogeneous intensity on the whole beam, or approximately homogeneous in that the intensity can decrease between the center of the beam and the edges of the beam when one is in beam type "low beam", or a maximum intensity in the center and more diffuse on the sides .
  • the maximum intensity of the "high beam” beam is greater than the maximum intensity of the "low beam” beam, in particular about twice as high.
  • the shaping optics 10 has, in the illustrated example, the shape of a convergent lens, defining an optical axis 11 on which are arranged each of the light sources 2, 4.

  • At least one light source comprises one or more transmission means whose emission intensity can be modified, the light source being controlled according to the position of the cache by varying the intensity of the light. emission of the rays emitted by the source.
  • Each of the light sources can thus be controlled so as to modify the luminous flux emitted by this source as a function of the position of the mask, in a direction of reduction of the luminous flux or in a direction of increase of the luminous flux when the mask goes from one given position to another.
  • the two light sources can in particular be driven in opposite directions during the passage of the cache from one position to another.
  • Each optical deflection device 6, 8 comprises according to the invention a reflector 7, 9, these reflectors being respectively associated with one of the light sources 2, 4, each of the sources and the optical deflection device being made integral with a support 18 on which is also reported a heat exchange device 20.

  • each reflector being secured to the support 18 to be in a specific position relative to the corresponding light source.
  • each reflector has a shell shape with a reflective inner surface 22 elliptical or substantially elliptical, so that each reflector has two focal points, with the light source corresponding which is positioned at the first focus of the reflector.
  • the light source emits the majority of its light energy towards the reflecting inner surface and, because of its arrangement in the vicinity of the first focus of the reflector, the emitted rays are deflected towards the second focus of the reflector.
  • the rays are deviated to pass precisely to the second focus, or to move to greater or lesser spreading distance. around the second focus, and thereby form a spot capable of forming the appropriate beam after projection by the shaping optics.
