Definitions

  • the invention relates to vehicle headlights, in particular those fitted with an elliptical type reflector.
  • a projector of this type conventionally comprises a light source, an elliptical type reflector, a first focus of which is located near the source, a converging lens including a focal plane passes in the vicinity of a second focus of the reflector and a lens for closing the projector.
  • the lens may be formed by the lens itself.
  • Such a headlamp When such a headlamp must generate a cut-off beam regulatory such as a passing beam or a fog beam, it has a cover or screen interposed between the light source and the lens, which obscures the part of the radiation, which would otherwise spread over this cut.
  • a cut-off beam regulatory such as a passing beam or a fog beam
  • a difficulty with this type of projector then lies in the modification of the cut profile.
  • Such modification should be considered especially when a projector, designed for example for a sense of right-hand traffic, must form a light beam, cut, suitable for a left hand traffic. It may also be desirable to carry out a universal projector capable of selectively generating a beam of crossing, an anti-fog beam or an unbroken beam.
  • the document EP 0794 382 for example presents a projector equipped with a movable screen with vertical sliding to form on command a beam cut-off and operated for this purpose by an actuator.
  • An object of the invention is to provide a projector allowing to generate one or more cut beams by means of a transition dangerous and visually comfortable.
  • a vehicle headlamp comprising a frame and at least one screening screen mounted movable in rotation about an axis of rotation relative to the frame, in which the axis is inclined relative to a main axis of lighting of the projector.
  • the inclination of the axis causes a visual transition relatively soft when changing the beam.
  • This movement of the screen does not generate an aberration. This transition is not dangerous.
  • the screen or screens can be given relatively dimensions important without encountering problems of space in the projector.
  • the projector 2 comprises a reflector 4 in the form of an ellipsoid of revolution around a horizontal longitudinal axis 6 forming a main lighting direction of the projector.
  • the projector has a lamp holder 8 attached to the reflector in part back of it.
  • the projector also includes a fixed lens holder 10 in the front part of the reflector 4 and a lens 12 fixed in the front part of the lens holder, a local plane of the lens passing in the vicinity of a second focal point of the reflector.
  • the lamp holder, the reflector, the lens holder and the lens are follow along the axis 6.
  • the reflector 4 and the lens holder 10 constitute here a projector frame.
  • the projector may further include a housing containing these elements.
  • the projector has a screen 14 rigidly fixed to the frame.
  • the screen 14 has a curved shape, substantially cylindrical with generator vertical and center of curvature located towards the front of the projector.
  • Screen 14 extends vertically over a small height and horizontally over approximately the entire width of the lamp holder. It has a horizontal upper edge extending 0.5% below the axis 6 with reference to the focus of the lens 12.
  • This fixed screen avoids any risk of glare during the movement of the screen support part as will be seen below.
  • This screen is fixed by two side tabs 15 pinched and sandwiched between the edges of the reflector and of the lamp holder.
  • the projector comprises a support part 16 of general shape conical although its shape is not strictly that of a cone.
  • the room 16 is mounted movable in rotation about an axis 18, the axis of the "quasi cone". This axis extends in a vertical plane and is intersecting with the main axis 6. It intersects this axis in front of the fixed screen 14, approximately at the level of the lens 12.
  • the support part 16 is rigidly fixed to a shaft 20 extending along axis 18.
  • the support part 16 forms four mobile screens 22, 24, 26, 28 each capable of intercepting a portion of the beam reflected by the reflector 4 when the screen extends in the vicinity of the main axis 6.
  • the support part 16 is mounted movable in rotation about its axis 18 so that it can occupy four positions relative to the frame, separate from each other by a quarter turn and corresponding to the cooperation of respective screens with the beam.
  • the support part 16 when the screen 22 cooperates with the beam, as in the figures. This cooperation allows define the entire upper quarter of the support piece. So the support piece has a front face 30 centered on the axis 18 and inclined upwards and towards forward. It also has a “quasi-conical” face 32 of which a portion 32a associated with the screen 22 extends generally towards the rear in FIGS. 1 to 3. The generator of the portion 32a of this face 32 intercepting the cutting plane vertical in Figure 1 is vertical.
  • the screen 22 is formed at the junction between the face 32a and the face 30.
  • This junction extends from one to the other of its ends in a general plane horizontal passing in the vicinity of axis 6, as shown in Figure 1. From more, this junction has in top view a general curved shape similar to that of the fixed screen 14.
  • the mobile screen 22 extends over the entire width to a distance from the fixed screen 14 which is small and essentially constant the along the fixed screen. However, the ends of the fixed screen extend laterally beyond those of the mobile screen 22 which is shorter.
  • the junction between the faces 32a and 30 is truncated by a song of a certain thickness constituting the screen 22. This song has generators intersecting at focal point of the lens 6. The generator at the axis 6 is confused with this axis.
  • the cutoff profile is that referenced TD in FIG. 4 and is suitable for conventionally generate a passing beam for right-hand drive.
  • the rear portion 32a is shaped to connect the edge 22 to the shaft 20 of the in the least bulky way possible. It has a shape approaching that of a portion of cone.
  • the other three parts of the support part 16 are defined so similar in combination with the other three screens 24, 26 and 28.
  • the face front 30 thus has a generally square shape with curved edges with center of curvature directed forward.
  • the mobile screens 24, 26 and 28 are here formed to define bundles known per se and respectively illustrated in FIG. 4. These are respectively a left-hand drive (TG) passing beam, a main beam and a passing beam for driving on roads wet (AW). The latter in addition to cutting the passing beam avoids lighting of the road area in front of vehicles coming in reverse. Also, the conductors are not dazzled by the beam which otherwise it would reflect on them.
  • ML highway driving
  • the projector has an actuator 34 in the form of a stepper motor no shaft 20, controllable by the driver from the dashboard of the vehicle.
  • This actuator is associated with a stabilization device 36 comprising a duct 37 radial to the shaft 20 and opening onto the latter, in which is movable a ball 39 biased towards the shaft by means of a spring.
  • the shaft has four ball housings corresponding to the four positions of the support part. This device reduces the risk of untimely rotation of the mobile screen support part 16 without the engine being activated.
  • the motor 34 makes it possible to rotate in rotation around the axis 18 the four screens 22, 24, 26 and 28 and to position the support part so as to define the cut-off with the mobile screen selected by the driver by depending on the circumstances.
  • the support piece 16 can be made so that its more large dimension, for example between the extreme edges of two screens opposite, less than about five centimeters. It can also be made of a thin metallic material, for example a few tenths of a millimeter. As a result, the moving part, support for different types of screens, presents only a very low inertia.
  • the motor 24 may have only a low power, of the order of 1 to 2 Watts. Such an engine will then be inexpensive, and will consume little Electric power. We could even use a friction actuator system driven by a deformable piezoelectric element.
  • the time to response of this structure could be very weak: it is possible to switch from one position to another by a rotation at high speed, the time of transition between two positions being of the order of 100 milliseconds. With some switching time of this order of magnitude, the driver of the vehicle does feels any discomfort that could be caused by the shape of the cut in transition phase. Similarly, drivers of oncoming vehicles reverse are not likely to be dazzled during a cut change.
  • the lamp 9 may be a halogen lamp or a lamp with dump.
  • the actuator 34, the ball device 36 and the screen support mobile 16 may extend in whole or in part through openings reflector 4 and / or lens holder 10. These openings are few visible from outside the projector. In addition, they practically do not alter not the operation of the projector.
  • the lower openings of the reflector 4 do not alter not substantially the beam formed by the reflector.
  • the motor, the stabilization device and the screen support extend opposite an area of the reflector not very useful for the definition of the beam and therefore not detrimental to its formation.
  • a mobile screen when a mobile screen extends in the vicinity of axis 6 in position to form a cut, its distance from the fixed screen will be 0.1 to 0.2 mm.
  • the inclination of the axis 18 combined with the taper present the advantage that the edge of the screens follows the field curve of the lens 12, which is in the first order comparable to a circle.
  • This provision is particularly favorable for obtaining optimal optical quality for beam.
  • a inclination of the axis 18 relative to the optical axis 6 between 5 and 50 °, in depending on the lens in question, fulfills this condition. With a projector currently in series, an angle of 20 ° gave the best results.
  • the projector according to the invention also has the advantage that the mechanical device is particularly simple even when combined with a high number of mobile screens.
  • the reduced size of the motor 34 associated with the inclination of the axis 18 allows the motor 34 to be housed practically inside the volume delimited by the reflector 4 and the lens holder 10, the projector thus equipped having the same footprint, and the same aspect, as a projector having only one screen fixed providing a single cut.
  • Support part 16 may be associated with a number of screens other than 4 for example, 2, 3, 5, or more. It can even be associated with a single screen.
  • Provision may be made for the axis of rotation 18 of the support piece of mobile screens is slightly inclined relative to the median vertical axis of the projector if this is advantageous in terms of space or performance optical. Preferably, this inclination will not exceed a few degrees.
  • other types of cut beams than those previously described are possible in association with the present invention.
