Definitions

  • the headlamps of a vehicle shall illuminate portions of road at different lengths in front of the vehicle, without dazzling other road users, whether they are traveling in the same direction or in the opposite direction.
  • the shortest range of light with which a vehicle can follow or cross another vehicle is that which corresponds to the low beam.
  • the cutoff line of the projector is oriented with a slope of 1%. Under these conditions, the light rays illuminate the ground for about 70 meters ahead of the vehicle. This distance, however, depends on the height of the projector relative to the ground.
  • the document US2006039158 describes a cover that has two extreme positions corresponding to the low beam and high beam, and between these two positions several intermediate positions.
  • the document DE102004063836 proposes an electronic system to adapt the range of the projectors according to the traffic conditions.
  • the document US6550944 discloses a device that modifies the intensity distribution by moving an element of the optical module so as to modify the orientation of the light rays within the module.
  • EP1746340 also describes a device for enhancing the intensity of the light beam emitted by the projector.
  • An additional optical element called "folding" is associated with the cache, this element captures some of the rays directed against the cache and returns them over the cache.
  • Such a mode of construction gives good results.
  • the intensity of the beam emitted by the light source in low beam is sufficient without the folder to follow or cross another vehicle without risk of blindness.
  • Patent applications EP985577 and EP1679226 describe constructions of this kind.
  • an elevation of the beam redistributes the flux emitted by the lamp. If the beam is raised, the range increases, but the area near the vehicle is less illuminated.
  • An “optically active position” is understood to mean a position of the cache such that it intercepts a portion of the rays emitted directly by the source or reflected by the reflector.
  • the “extreme” position is the “active” position where the cache intercepts the most rays, the one where it is in the most raised position generally, in contrast to the optional intermediate position.
  • the module is a so-called bi-function module, which can for example operate in code mode (active position of the cache creating a given cut-off beam) and in road mode (retracted position of the cache).
  • the module is a tri-function module, able to emit a second cut-off beam different from the first.
  • the cover can be movable according to different types of movement, it can be a translation, for example in a substantially horizontal plane and perpendicular to the optical axis of the module. It can also be rotated about an axis, or combine translational and rotational movements, for example.
  • the optically extreme active position of the cache corresponds to the emission by the module of a code beam. It is in this case that it is indeed wise to optically inactivate the folder to avoid it returns more light above the cut, which could make the beam code illegal.
  • the optically intermediate active position of the cache corresponds to the emission by the module of a motorway beam.
  • the cover and folder can be associated in different ways: they can be mounted jointly to one another, they can also be an integral part of the same element. They can also be independent components, which can be animated with different movements.
  • the cache is mobile, and the folder can also be mobile (having the same movements as the cache or not) or be static.
  • front is understood throughout the present text according to the position of the module once integrated, possibly in a projector, and mounted on a vehicle in normal operating mode.
  • An additional optical member is associated with the cache. This body called "bending" is located between the light source and the cache. It can be associated with the cache. Its basic function is to intercept some of the light rays that are directed against the cache and send them back over the cache so as to enhance the intensity of the light beam emitted by the projector for at least some of the positions of the cache.
  • the movements of the folder and the cover are synchronized so that the cover is movable in a direction substantially perpendicular to the optical axis of the projector (and preferably substantially in a vertical plane) to provide a line clear cut and precise and also to control one or more intermediate positions.
  • the folder is then advantageously "masked” or “optically inactivated” when the cover is in the extreme optically active position: the folder enters into action only when the cover is in an intermediate position, and the folder becomes inactive ( optically) when the cover is in a passive / retracted position.
  • the Figures 2 to 5 illustrate a first embodiment of the invention.
  • the cache 23 is an opaque element. It has at its top a reflective surface 25 oriented parallel to the optical axis of the projector which forms the folder.
  • the surface 25 is for example a film or a thin reflective coating which is deposited at the top of a block which forms the cover.
  • the folder follows the path of the cutoff line, that is to say it has for the illustrated embodiment two bearings 25a, 25b separated by a connecting slope 25c.
  • the cover 23 is movable perpendicular to the optical axis of the projector, and it is in the active position where it intercepts a portion of the light rays emitted by the light source 22.
  • the cutoff line of the projector is centered on the axis optical yy of the projector.
  • the reflecting surface 25 is not very active, that is to say that it intercepts few light rays because the reflecting surface 25 is in a part of the space where the concentration of the rays is less.
  • only part of the cover may have a reflective coating, particularly only one of the bearings of the cutoff line could be reflective.
  • the blade is shorter than the cut-off line and extends only along part of the length of the line. According to another variant, the blade is reflective only over part of its length.
  • the cache 43 has a traditional structure.
  • the folder 45 is the reflective upper surface of a block 45a located near the cover on the side of the light source.
  • Block 45a is translucent (transparent) that is to say that it can be crossed by light rays without significantly disturbing their direction or intensity.
  • the block is for example a glass block 2 to 10 mm, in particular 2 to 4 millimeters thick, and preferably 3 or 5 millimeters, whose upper surface is aluminized and is placed in such a way that the reflecting surface 45 is in the immediate vicinity of the optical axis of the projector, just a little below the cutoff line of the cache in its active position.
  • the folder may be shaped so as to follow the contour of the cut line of the cover 43. Also, the folder may cover only part of the length of the cut line.
  • the figure 10b illustrates a variant of the figure 10a as regards the block 45: the front face 45b of the block is inclined towards the front (it is understood in all the text by "front” or rear "the positioning of the considered surface according to the path of the light from the source towards the output of the optical module) of an angle ⁇ of about 17 ° with respect to the vertical represented by the axis ⁇ (measured inversely in the trigonometrical direction). And the rear face 45c of the block is inclined backwards by an angle ⁇ 'also about 17 ° relative to the vertical (in the trigonometrical direction).
  • the figure 10c is a variant of the figure 10b : the front face 45b of the block is more inclined forward than the rear face 45c is backward.
  • an angle ⁇ of about 20 ° and an angle ⁇ 'of about 5 °. It has been found that it is the inclination of the front face 45b of the block that is most effective for deflecting the spokes in a controlled manner, and the rear face can therefore have a smaller inclination, or even be simply in a plane. vertical as at the figure 10a .
  • the mask hides the folder when it is in the active position. In addition, it is moved according to two distinct modes of displacement.
  • the movement of the cover 3 is controlled by a motor 55 and via a transmission assembly 56.
  • the motor is of any suitable type, for example it is a DC motor, or a stepper motor .
  • the transmission assembly is for example a screw mechanism which converts the rotation of the motor shaft into a translation.
  • the first member 64 is an electromagnet whose stroke is substantially equal to the race of the cover between its active position and its passive position.
  • the electromagnet allows rapid movement of the cover between these two positions.
  • the second element 65 is a motor, for example a stepper motor, which drives a screw mechanism that converts the rotation of the motor shaft into a translation. This member provides low amplitude movement of the cache between an active position and an intermediate position.
  • the displacement member of the cover 73 is a cam 74 driven in rotation by a motor 75.
  • a spring 76 recalls the cover so that it is in contact with the cam.
  • the figure 18 shows the cam path 74a in developed.
  • a first segment 75 corresponds to the active position of the cache, which corresponds to the low beam.
  • the following segment 76 has a low slope, it ensures a small amplitude displacement of the cache in one or more intermediate positions depending on the rotation angle of the cam.
  • the means for moving the cache are controlled by any appropriate means, automatic or manual.
  • it is a radar that detects the distance with the vehicle tracked or encountered, or any other device.
  • control of the present device can be achieved in coordination with a correction device which adjusts the light beam according to the attitude of the vehicle, that is to say that the same optical elements or the same control elements can be used to improve the range of the projector according to the invention, or to achieve a beam correction in relation to the attitude of the vehicle.
  • the module can be used both for the regulatory lighting functions and for the AFS functions that have been mentioned at the beginning of the description and generally for any lighting or signaling function that the projector is likely to fill.
  • this module can be coupled with an automatic switching device from one type of beam to another, such as for example that described in the patent application. FR2877892 .
