Definitions

  • the field of the present invention is that of automobile equipment and, more particularly, that of light projectors for these motor vehicles.
  • Motor vehicle headlamps generally comprise a reflector in which are arranged a light source and means for controlling the shape of the beam emitted by said source to adapt it to the circumstances of driving.
  • the reflectors generally take the form of a paraboloid or an ellipsoid of revolution, for which the light source is positioned at the level of the focal point or one of the focal points of these surfaces.
  • the light source is conventionally positioned at a first focus and a lens is positioned on the optical axis so that its own focus coincides with the second focus of the ellipsoid.
  • a mirror is then placed at the level of the second focal point, to reflect upwards the light rays which arrive there.
  • LED diodes for Light-Emitting Diode, for light-emitting diodes
  • the light power emitted by these devices remains limited for the moment and it is necessary to use it as well as possible. It is therefore desirable to be able to dispense with the cut-off cover which absorbs, in the dipped beam position, substantially half of the luminous flux emitted.
  • the beam deflection mirror between a position corresponding to the dipped headlights, where it returns all the rays to the top of the reversing lens, and a position corresponding to the high beam, where it does not interfere with the light rays and lets them reach the bottom of the lens.
  • the object of the present invention is therefore to remedy these drawbacks by proposing, in particular for multiple headlights with semi-elliptical reflectors, a simplified actuation device.
  • the subject of the invention is a multi-module headlamp for a motor vehicle, each module constituting said headlamp comprising at least one light source and at least one movable beam interception member capable, depending on its position, of intercepting or to allow part of the light beam from said source to pass, characterized in that the interception members of at least two modules are common or actuated by a common setting means.
  • This pooling makes it possible to reduce the number of parts necessary for controlling the passage from main beam to dipped beam, and vice versa, and simplifies the production of the headlamp.
  • each module comprises a reflector, said source of said module being positioned at a point, called first focus, of said reflector and said reflector having a shape such that at least part of the rays coming from said source converges after reflection towards a point, called second focus, of said reflector.
  • the reflectors of said two modules are open portions of ellipsoids or half-ellipsoids extending above a plane of symmetry of said ellipsoid.
  • the foci of the reflector are then the foci of the ellipsoid.
  • Said two modules are preferably positioned side by side, their optical axes being parallel, and their second focal points have the same abscissa on said optical axes. This proximity simplifies, for its part, the production of the control means for the passage from main beam to dipped beam, and vice versa.
  • the reflectors of said two modules are half-ellipsoids extending above a plane of symmetry of said ellipsoid and the beam interceptor in said two modules is a reflecting surface oriented upwards with respect to the plane of symmetry of said ellipsoid.
  • the reflective surfaces of the two modules are plane mirrors placed, longitudinally, substantially at the level of the second focus of their reflector, said modules further comprising a device for reversing its beam to redirect the light flux from the second focus into a direction parallel to the optical axis.
  • the reversing member is, for at least one module, a lens whose focal point is positioned longitudinally substantially at the level of said second focal point of the corresponding reflector.
  • said plane mirrors are rotatable around the same axis, oriented perpendicular to the optical axis.
  • the axis of rotation comprises a toothed sector extending in a plane substantially perpendicular to the longitudinal direction of the axis of rotation.
  • the axis of rotation is driven by a single motor meshing with said toothed sector.
  • the motor supplies a torque against a rotating return spring.
  • This device guarantees the return of the headlight to dipped beam in the event of a failure of the motor for actuating the beam interception means.
  • said reflective surface is a complex surface capable of directly generating the shape of an automobile headlight beam from at least part of the light beam coming from said second focal point.
  • the light source of at least one module is a light-emitting diode.
  • a motor vehicle headlamp 1 of the prior art which is constituted by a reflector 2, having substantially the shape of an open portion of an ellipsoid, inside which is placed a light source S, and by a convergent lens 3 which is positioned in front of the reflector.
  • the light source S is positioned at the first focus of this ellipsoid, on the bottom side of the reflector 2, and it emits over the entire solid angle formed by the ellipsoid. All the light rays emitted are directed, after reflection on the reflector 2, in the direction of the second focus F of the ellipsoid.
  • the lens 3 is positioned longitudinally on the optical axis xx of the projector 1 in a position such that its focal point is approximately at the level of the second focal point F of the ellipsoid. In this way the light rays coming from the reflector 2 are straightened to be substantially parallel to the optical axis at the output of the lens 3. A light beam is thus obtained which illuminates the road in the distance, in a high beam position. It is then necessary to provide a cut-off mechanism (not shown) to eliminate, before it passes through the lens, the lower part of the beam and perform the dipped beam function.
  • the figures 2 and 3 show a semi-elliptical headlamp with a moving mirror, respectively in the main beam and dipped beam positions.
  • the reflector 12 comprises, here, only the upper half of the ellipsoid portion of the previous case. Consequently, the light source only emits over a solid angle of 2 ⁇ steradians, ie, in section along a vertical plane passing through the optical axis, as shown in the figures, over a sector of 180° directed upwards.
  • This configuration is particularly well suited to a light source formed by light-emitting diodes LED, which only emit over a solid angle of 21 ⁇ steradians.
  • the luminous flux is directed, after reflection on the reflector 12, towards the second focus F of the ellipsoid then towards a converging lens 3. Due to this emission over 2 ⁇ steradians, the light beam is only directed towards half lower part of the lens 3.
  • the shape of the lens and/or the position of its focal point with respect to the second focal point F of the ellipsoid, is such that in the absence of any means of derivation of the beam, the latter is redirected towards the front.
  • a movable mirror 4 is positioned at the level of the second focus F. Its reflective surface is directed upwards so as to be able to intercept the luminous flux coming from the reflector 12.
  • This mirror 4 is movable around a horizontal axis so as to position its reflective surface, either in a horizontal plane passing through the optical axis xx, or, in a plane inclined forwards with respect to the horizontal, in a so-called retracted position.
  • the mirror 4 is inclined with respect to the horizontal plane and is positioned entirely outside the luminous flux, thus allowing all the rays to pass in the direction of the lens 3. These pass through the lower part of the lens and are straightened towards up to illuminate the road over a long distance. We thus find us in the position of the main beam headlights, without loss of the light power emitted by the source S.
  • the mirror 4 is in a horizontal position and its longitudinal span is sufficient to intercept all the rays which come from the reflector 12. All these rays are reflected upwards by the mirror 4 and are redirected by the latter towards the upper part of the lens 3.
  • the light rays are sent forwards, but with a downward inflection, which makes it possible to illuminate the road over a given distance.
  • the downward deviation is obtained by the shape given to the lens 3 and/or by shifting the focus of the latter with respect to the second focus of the ellipsoid. We then find our in the position of the dipped headlights, this time again without loss of the light power emitted by the source S.
  • FIG 4 and 5 show, respectively in high beam and dipped beam configuration, a headlight 11 which consists of two semi-elliptical LED modules 11a and 11b, juxtaposed one beside the other, whose axes of symmetry are parallel.
  • module of a headlamp is understood to mean a light system in which all or part of the rays coming from a light source are reflected by a reflecting surface in the direction of a focal point called the focal point.
  • each module comprises a reflector, respectively 12a and 12b, in which is placed a light source (not visible), and comprises a mobile mirror, respectively 4a and 4b, which can move in rotation around a horizontal axis, transverse with respect to the direction of the optical axis of the modules.
  • the light sources are positioned at the first focus of each of the reflectors
  • the mobile mirrors are positioned at the level of the second focus of these same modules.
  • the rotation of each of the mirrors makes it possible to produce a beam either in the main beam configuration (mirror lowered), or in the dipped beam configuration (mirror raised).
  • the invention recommends, for example, mounting the movable mirrors on a common axis 5 which is oriented perpendicular to the optical axis.
  • This axis is driven in rotation by means of a motor 6 and returned to a rest position, corresponding to the position of the dipped headlights, by a return means, such as for example a torsion spring 7.
  • a return means such as for example a torsion spring 7.
  • the return spring 7 is mounted on the shaft 5, and bears, on the one hand on the structure of the headlamp 11 and, on the other hand, on a stop 51 carried by the shaft 5.
  • motor 6 it is positioned at one end of axis 5, for example under one of the two modules as shown in the figure 4 Where 5 , and is fixed to the structure of the corresponding headlight module 11a.
  • the figure 6 shows, in sectional side view, the sectional plane located in the vertical plane of symmetry of the ellipsoid of the first module 11a, the detail of the various pieces of equipment and their relative positioning.
  • the positioning of the lens 3 (not visible) is, here, materialized by its support 8, which is placed on the optical axis xx, downstream of the second focus F of the reflector 12a.
  • the mobile mirror 4a is shown in its retracted position, corresponding to the position of the main beam headlights, and it has free space above it, in order to be able to position itself along the optical axis and thus take the position corresponding to dipped headlights.
  • the axis of rotation 5, carrying the mirror 4a rotates in bearings carried by the structure of the projector 11a and extends horizontally below the optical axis. It has an overall cylindrical shape of revolution with however, on either side of each of the mirrors 4a and 4b that it carries, facetted shapes on which support pieces 52 of said mirrors are wedged. These faceted shapes allow the mirrors to be driven in rotation when the axis 5 is itself driven in rotation by the motor 6.
  • the axis 5 comprises behind the cutting plane, that is to say between the two modules 11a and 12b of the preceding figures, a toothed sector 9 which is rigidly fixed to it and which extends in a vertical plane, downwards.
  • This toothed sector cooperates with the teeth (not visible) of a drive shaft coming out of the motor 6.
  • a rotation of the motor in one direction or the other, rotates the toothed sector which drives the axis 5 and, consequently, the mirror 4a via the faceted shapes of the axis 5 and the support pieces 52.
  • a rotation of the motor in the clockwise direction makes the axis 5 turn counterclockwise by compressing the return spring 7.
  • the toothed sector 9 is unique and the axis of rotation 5 is common to all the mirrors of the modules 11a, 11b, ..., which the projector 11 may have.
  • each projector module has its own motor for actuating its mirror, the invention thus makes it possible, with a minimum of means, to carry out the passage of all the modules from one position (code or road) to the other position and to have this rocker effected simultaneously to all projector modules 11.
  • Axis 5 has been represented in the form of a cylinder of revolution, with modules positioned side by side in alignment with this axis, but the invention can just as well be carried out with modules which are offset longitudinally or vertically. relative to each other, as long as there is a single means which is able to actuate the mirrors of the different modules.
  • the invention has been described with a combination of a plane mirror 4 and a lens 3 which reverses the light rays and which gives the desired shape to the beam. Not according to the invention, it could just as well be produced by a single beam reversal member, such as a mirror having a complex shape which returns the light beam forwards, giving it the desired shape.
  • a single beam reversal member such as a mirror having a complex shape which returns the light beam forwards, giving it the desired shape.
  • the passage from the configuration of the main beam to the dipped beam remains, in this case, ensured by a displacement of the mirror with a complex shape, which is thus mobile as is the plane mirror of the configuration described.
  • the means for intercepting the beam to pass from main beam to dipped beam has been described in the form of a mobile mirror in rotation around an axis transverse to the optical axis. Not according to the invention, it could just as well be made in the form of a mobile cover which would be mobile in vertical translation or by any other mobile means, provided that it is capable of taking up several positions in which, either it intercepts part of the beam and reflects it, or it lets it pass.
  • the projector described has the shape of a half-ellipsoid, but the principle of a common means for actuating the device for intercepting the beam in several modules could also apply in the case of a complete ellipsoid.
  • the invention has been described, by way of example, in the case of a headlamp which comprises a reflector, whether the latter is an ellipsoid or a semi-ellipsoid.
  • a headlamp which comprises a reflector
  • the light emitted by the light source such as LEDs for example, then being directed directly on the mobile interception means which passes the beam from the main beam to the dipped beam, and vice versa from the dipped beam to the main beam.
