Definitions

  • the present invention relates to a light beam projection device with mechanical actuator, in particular for a motor vehicle, an optical module and a beam light projector, of the low beam or high beam type, provided with such a projection device.
  • an optical module of the housing notably comprises a light source, for example one (or more) electroluminescent diode (s), which emits light rays, and an optical system comprising one or more lenses and, optionally an optical element, for example a reflector, for orienting the light rays from the light sources, to form the output light beam of the optical module.
  • a light source for example one (or more) electroluminescent diode (s), which emits light rays
  • an optical system comprising one or more lenses and, optionally an optical element, for example a reflector, for orienting the light rays from the light sources, to form the output light beam of the optical module.
  • Electroluminescent diode arrays such as matrices for example, are often used to obtain such a beam.
  • Each light emitting diode provides a component of the light beam coming out of the optical module.
  • a large number of diodes makes it possible not only to increase the brightness, but also to improve the resolution of the illumination obtained. Indeed, the beam then comprises more components for the same light beam.
  • the dies also make it possible to activate each light-emitting diode individually.
  • the individual activation of certain diodes gives the possibility to modulate the shape of the beam, or even to modify its extent lateral when there is potentially a wider beam than that used, and it is necessary to select a portion of the diodes only.
  • the projected beam has light holes in the direction of the vehicle detected in order to avoid dazzling the driver of the vehicle crossed or followed, while keeping a wide illumination on both sides of the vehicle.
  • the light hole or holes follow the movement of the detected vehicle; they move within the projected beam.
  • This function requires a high resolution of the beam, especially to define the mobile shadow area with high accuracy.
  • the invention therefore aims to obtain a projection device configured to project a light beam, which is capable of performing functions such as the aforementioned function with a high resolution, and keeping a reduced number of diodes.
  • the invention relates to a device for projecting a light beam with a mechanical actuator, in particular for a motor vehicle, comprising an array of light sources able to emit light rays to form the light beam along an optical axis, each source of light defining a component of the light beam having an initial resolution angle in a plane.
  • the device is remarkable in that it further comprises a mechanical actuator configured to move at least one element of the device so that the optical axis of the light beam is displaced between at least two projection directions in a periodic oscillatory motion to a determined displacement frequency, the projection directions forming between them a substantially coplanar displacement angle of the resolution angle, the displacement angle being equal to a fraction of the initial resolution angle of the beam.
  • the device therefore makes it possible to increase the resolution of the beam without having to add additional light sources. In particular, energy consumption and the risks of overheating due to a large concentration of sources are minimized. In addition, it allows the use of standard electronic components rather than more complex components to produce.
  • the invention also relates to an optical module comprising such a device for projecting a light beam with a mechanical actuator.
  • the invention also relates to a motor vehicle headlight provided with such an optical module.
  • the Figures 1 to 5 represent five different embodiments of the projection device 1 of a light beam with mechanical actuator according to the invention.
  • the projection device 1 may in particular be part of a motor vehicle headlight optical module, which is provided with projection lens means which partly form the light output beam of the optical module.
  • the lens means are represented by a single projection lens 3.
  • the device 1 comprises an array of light sources capable of emitting light rays to form the light beam and an optical system configured to partially form the light beam from the light rays from the light sources.
  • the network is for example a matrix of light-emitting diodes
  • the optical system is for example a single lens, or a correction lens or a system of several lenses which serves to homogenize the light beam and / or to correct optical aberrations.
  • the array of light sources and the optical system are represented together by a single element, which will be called source assembly 2 in the description.
  • Each light source of the network provides a component of the light beam projected by the device 1.
  • the light beam emitted by the device leaves the projection lens 3 along an optical axis 4.
  • the light beam 13, shown schematically on the figure 6 is divided horizontally into several components 10, here extended vertically, each light source of the network defining a component 10 of the beam 13. Each rectangle therefore corresponds to a component 10 of the beam 13 emitted by a different source.
  • the array is a series of aligned light sources, for example a light-emitting diode array.
  • the optical axis of the beam 13 is represented by a central point 22, the vertical and horizontal arrows illustrating the axes 11, 12 of a fixed reference in the space.
  • the beam 13 also has a resolution angle defined in the horizontal plane, the horizontal plane being defined by the horizontal axis 11 and the resolution angle by the double arrow 24. In the description, the beam resolution angle 13 is taken as an example equal to 1 °.
  • the device 1 is configured to periodically move the optical axis of the light beam 13 between two projection directions.
  • the device 1 is provided with a mechanical actuator 5 adapted to move in translation the source assembly 2 of the device relative to the projection lens 3.
  • the mechanical actuator 5 is a mechanical actuator with two positions, for example an electro magnet, a motor provided with a cam, a stepper motor or a piezoelectric motor.
  • the source assembly 2 is driven in a plane substantially parallel to the projection lens 3.
  • the source assembly 2 moves between two extreme positions, the first position corresponding to a first direction of projection of the optical axis beam, and the second position corresponding to a second direction of projection of the optical axis.
  • the figure 6 represents the beam 13 and its optical axis (point 22) in the first direction
  • the figure 7 represents the beam and its optical axis (point 23) in the second direction.
  • the vertical axis reference 12 and horizontal 11 being fixed, the beam shifted to the left.
  • the horizontal difference in position of the points 22 and 23 relative to the horizontal fixed reference point 11 corresponds to half the resolution angle represented by the double arrow 24.
  • the source assembly 2 For a beam with vertical components 10, such as that of the figure 6 , the source assembly 2 is moved horizontally so that the axis of the beam moves along the horizontal axis 11. The displacement of the beam is therefore substantially in the component division plane 10 of the beam 13. If the beam 13 was vertical with horizontal components, the source assembly 2 would be moved vertically. Thus, the two directions of the optical axis of the beam 13 form between them a substantially coplanar displacement angle of the beam resolution angle.
  • the two extreme positions are chosen so that the angle of displacement of the optical axis of the beam 13 is equal to a fraction of the angle of resolution of the beam 13.
  • the The angle of displacement between the two positions is preferably substantially equal to half the resolution angle, i.e. 0.5 ° here.
  • the source assembly 2, and therefore the axis of the beam 13, is further moved between the two positions by the actuator 5, at a determined displacement frequency not perceptible by the human eye.
  • a frequency must be greater than 40 Hz, and is preferably between 100 Hz and 200 Hz.
  • an observer looking at the projected beam 13 is not able to discern the two directions of the beam 13.
  • the observer sees a superposition of the two directions of the same beam 13, that is to say beam 13 of the figure 6 when the optical axis is in the first direction, and the beam of the figure 7 when the optical axis 13 is in the second direction.
  • the figure 8 shows us the effect obtained by this superposition, and the beam 13 which is really perceived by an observer.
  • the beam 13 then has a resolution angle 25, represented by the double arrow, which is twice as small as that of the original beam, that is to say 0.5 °.
  • the resolution of the beam has been multiplied by two.
  • the mechanical actuator 5 is furthermore configured to move the source assembly 2, and therefore the optical axis of the light beam 13, discontinuously, so that the optical axis of the light beam 13 is maintained in each of the two directions. during a hold time which is greater than the transition time between the two projection directions. In other words, the movement does not follow a movement at a constant speed.
  • the displacement follows a periodic function substantially in slots.
  • the top plates 16 and bottom 17 of the slots correspond to the holding time in each of the two extreme positions, and the slopes 18 each joining a top plate 16 to a bottom plate 17 correspond to the transition time.
  • the hold time lasts about four times longer than the time of transition.
  • the holding time is at least four times longer than the transition time, preferably at least twenty times, more preferably at least fifty times.
  • the figure 10 shows a beam 13 comprising vertical and horizontal components, the source array being for example a matrix of light-emitting diodes.
  • the figure 11 illustrates the beam 13 perceived by an observer when the beam 13 is moving through the device 1 according to the invention.
  • the beam 13 is moved horizontally, in a manner similar to the example of the Figures 6 and 7 , and provides increased horizontal resolution.
  • the light sources are individually activatable in order to be able to extinguish certain components of the beam while the other components remain on.
  • a shadow zone appears in the beam 13 whose resolution angle is equal to 1 ° in the previous example, the beam 13 being fixed.
  • the Figures 12 (a) and 12 (b) show an example of a light beam with a shadow zone produced by the third component extinguished on the Figure 12 (a) , and the fourth component extinguished on the figure 12 (b) .
  • the resolution angle of the shadow area is reduced to 0.5 °.
  • the shadow areas 21 can appear only on certain resolution angle components of 0.5 °, a complementary component always being lit. Specifically, only one resolution angle component of 0.5 ° out of two of the beam may appear off.
  • the light sources are activated at an activation frequency which is synchronized with the movement frequency of the light source. mechanical actuator 5.
  • This synchronization is illustrated in FIG. figure 12 .
  • the Figure 12 (a) shows the light beam 13 oriented in the first direction, and the figure 12 (b) the same light beam 13 oriented in the second direction.
  • the light source defining the third component is inactive, and on the figure 12 (b) it is the light source defining the fourth component which is inactive.
  • the activated source is alternated simultaneously with the change of direction of the beam 13 to obtain the shadow zone on the desired component.
  • the extinguished component is thus shifted in the opposite direction to the displacement of the beam 13.
  • the activation frequency is substantially equal to the beam displacement frequency.
  • the Figure 12 (c) is a graph showing the light intensity 19 of the beam 13 having a single shadow area corresponding to a single resolution angle component 26 of 0.5 °.
  • the superposition of the two beams 13 of Figures 12 (a) and 12 (b) leads to a resolution angle component of 0.5 ° which is completely extinguished because it comes from a superposition of two shadows, as shown by the dotted lines 27 of Figures 12 (a), 12 (b) and 12 (c) .
  • This component 21 is surrounded on both sides by two components of luminous intensity whose value is half less than the normal luminous intensity of a component, because they are obtained by superposition of a shadow zone and an illuminated area.
  • the other components all have luminosities of normal intensity because they are obtained by superposition of two illuminated areas.
  • the mechanical actuator 5 is configured to periodically move the source assembly 2 between an intermediate position and another position to choose from two opposite extreme positions with respect to the intermediate position.
  • the periodic displacement between the intermediate position and the first extreme position makes it possible to reveal a resolution angle of shadow zone of 0.5 ° on the beam with an inactive light source.
  • the periodic displacement between the intermediate position and the second extreme position makes it possible to reveal a complementary shadow zone with a resolution angle of 0.5 ° on the beam with the same inactive light source. Consequently, the axis of the beam is oriented periodically between an intermediate direction and a second direction chosen from two extreme directions corresponding to the movement of the source element 2.
  • the mechanical actuator moves the source assembly, either between the intermediate position and the first end position, or between the intermediate position and the second end position.
  • Each move produces an effect similar to that of Figures 6 and 7 as for the reduction of the angle of resolution.
  • the synchronization of the activation of the light sources with the displacement of the beam is not necessary, because it is possible to reveal shadows on the entire beam.
  • FIG. 2 On the figure 2 is represented a second embodiment similar to the first, with the same elements bearing the same references. The difference comes from the mechanical actuator 5 which here rotates the source assembly 2. To move from one position to another, the source assembly 2 follows a curve 6 corresponding to the focal curve of the projection lens 3, whose image focal point 7 is shown.
  • This embodiment is advantageous, particularly as regards the curvature of the field, when the optical system of the source assembly 2 is simple, with a single lens for example.
  • the first embodiment is however advantageous for more complex optical systems.
  • the mechanical actuator 5 only displaces the projection lens 3 in translation.

  • the mechanical actuator 5 rotates all the other elements of the device 1, that is to say that the source system 2 and the projection lens 3 are jointly moved around the same axis.
  • This embodiment corresponds to the displacement of an optical module in rotation about an axis, horizontally or vertically.
  • the device 1 comprises a mirror 9 configured to reflect the light beam from the source assembly 2 to the projection lens 3.
  • the mechanical actuator 5 moves the mirror 9, or in translation when the mirror 9 is the only one element to move, or to rotate when moving together with the source assembly 2.
