Definitions

  • the invention relates to an optical module for a motor vehicle headlamp, giving at least one cut-off beam, of the type of those comprising a projection system, for example a lens, and a light source disposed for example behind the lens it is separated by air, the light source preferably comprising at least one light emitting diode (which will also be designated later by the abbreviation LED (for "Light Emitting Diode” for the sake of brevity).
  • a projection system for example a lens
  • a light source disposed for example behind the lens it is separated by air
  • the light source preferably comprising at least one light emitting diode (which will also be designated later by the abbreviation LED (for "Light Emitting Diode” for the sake of brevity).
  • the invention relates in particular but not exclusively, according to one embodiment, to the LED module according to the European patent number deposit EP 06 291 391.9 filed September 1, 2006 in the name of Valeo Vision, incorporated by reference in the present application, which describes methods of constructing light projector modules giving a cut-off beam, for a motor vehicle, comprising a lens and a light source disposed behind the lens of which it is separated by air, the light source being formed by at least one light-emitting diode, such that the exit surface of the lens is selected so that it can be connected in a smooth and continuous manner with the output of similar neighboring modules, by determining the entrance surface of the lens so as to obtain the cut-off of the light beam without using an occulting cover.
  • the modules of this type can be used as unitary modules for making a beam or a portion of a beam with horizontal or oblique cut-off. If it is intended to emit a beam portion, it may be supplemented by another complementary beam, emitted by a different and already known module, using example of conventional halogen or xenon light sources (or power LEDs). It is thus possible to use this module so that its cut-off beam completes the beam code of an elliptical module bi function code / route, in particular to obtain a global beam type highway code.
  • the object of the invention is then to be able to produce an additional beam, in particular to complete a road-type beam in the upper part, without resorting to an additional optical module, without substantially increasing the space requirement of a projector containing, for example, example, a code / route module and an additional module type highway code (or, more broadly, any other module assembly to perform all regulatory functions expected from a motor vehicle headlight).
  • optical projection system is understood to mean one or more optical elements capable of creating a cut-off beam from a light source devoid of an occulting element participating in the formation of the beam cutoff.
  • the secondary light-emitting diodes are arranged at least in part, in particular predominantly or even totally, within the volume delimited by the main optical system.
  • the secondary light-emitting diodes are disposed substantially outside the path of the light rays emitted by the main light source or sources.
  • a main module in which one comes to insert a secondary system that does not come, or substantially not interfere with the main system, and obtaining a very welcome space saving, given the tendency to the compactness of the car headlights, coupled with a demand for more and more features.
  • the main light source (s) emit light directly towards an output lens of the main optical system. We are in "direct light”
  • the main light source or sources emit light in the direction of at least one reflective surface of the "folding" type. The light is then, in this case, at least deviated once before reaching the exit lens.
  • the projection optical system comprises an exit lens, in particular convex towards the front, and / or at least one reflector.
  • the invention thus proposes that a secondary beam is generated by a module already present in the projector, keeping little or no the initial volume of the volume of the module, and using this given volume to further functionalize it with one or more other sources bright.
  • the challenge has been to ensure that the main optical elements, in fact those present in the module initially installed in the projector, are not disturbed in their operation by adding the necessary secondary optical elements and vice versa.
  • main optical elements we can refer to the aforementioned European patent for more details, or to the examples described below for the version using an output lens, according to a first embodiment.
  • they comprise the lens and the light source comprising at least one light-emitting diode, said diode being disposed behind the lens from which it is separated by air, the exit surface of the lens being entirely convex towards the light-emitting diode. before and as it can be connected in a smooth, continuous surface with the lens exit surfaces of similar neighboring modules, and the input surface of the lens is defined so that the module provides a cut-off light beam without intervention of an occulting cover, in particular vertical.
  • the invention is therefore more particularly concerned with the variant in which the main LED is "in direct view" of the output lens, without the need for a "folding" type reflective surface.
  • the projection optical system in the form of a reflector may be associated with a reflecting mirror, and this reflecting mirror may also be the secondary reflective and / or scattering element of the secondary optical elements: thus has an optical element common to the main optical elements and the secondary optical elements.
  • the main direction of emission of the secondary light source or sources is towards the rear of the module.
  • This direction is in particular inclined downwards relative to the horizontal, particularly in the configuration where the secondary LEDs are arranged above the main source, or laterally, when the secondary LEDs are arranged laterally with respect to the main source.
  • the secondary reflective and / or scattering element forwards these rays.
  • the main direction of emission of the main light source is towards the front of the module and it is inclined, especially upwards, relative to the horizontal.
  • This particular configuration detailed in the patent mentioned above, makes it possible to obtain a smaller light beam than if the main LED were exactly opposite the entry face of the lens (configuration where the emission direction of the LED is parallel to the optical axis of the module and not oblique).
  • the secondary reflective and / or diffusing element is an element with a partly reflective and partly diffusing surface.
  • a substantially reflective surface can be used, such as an aluminized surface as used to usually make headlamp mirrors. But it is interesting here to have a surface that is at least partially diffusing too.
  • the ratio between reflection coefficient and diffusion coefficient can vary between 20/80 and 80/20, for example. To adjust the two coefficients, we can use a reflective surface and texture it to reduce its reflection and increase its diffusion in a controlled manner.
  • the element By being at least a little diffusive, the element will be able to return the light of the secondary LEDs with a greater angular dispersion, which is the goal sought: it is here that the secondary beam rather confers a "mood" illuminated by upper part of the photometric grid, so that it adds a light as light and widely distributed / spread as possible, especially horizontally, opposite the "spots" of bright light.
  • each of the secondary light sources there may be individual reflective and / or scattering elements for the or each of the secondary light sources (these individual elements may make superfluous individual elements of collimation of the source or sources).
  • the secondary reflective and / or scattering element may be a substantially planar element. This is the simplest configuration. It can also be curved, in particular curved in two different directions, in particular by being substantially convex.
  • the secondary reflective and / or diffusing element is disposed in front of the main light source.
  • the main light source will be disposed in or in the immediate vicinity of the focal plane of the lens, since it is sought that the beam obtained is properly focused.
  • the secondary reflective and / or scattering element By arranging the secondary reflective and / or scattering element in front of the main LED, it is defocused with respect to the lens, which makes it possible to obtain a secondary beam voluntarily defocused and therefore more diffuse in its distribution.
  • the reflective and / or diffusing element may also be placed behind the lens, but the "forward" configuration is preferred).
  • the secondary reflective and / or diffusing element may have, especially in the case where it is common to all secondary sources and where it is placed in front of the main source, a cut-out allowing the light emitted by the main light source to pass: its presence does not interfere with the cone of light emitted by the main source. It may have an indentation, or even be in several parts "around" the main source.
  • the secondary reflective and / or scattering element has, especially in the case where it is common to all secondary sources, an optically active surface at least below and / or on each side of the main light source.
  • This arrangement makes it possible to obtain a secondary beam placed at the top of the photometric grid (with respect to a conventional "road” distribution) and wide.
  • the collimation element or the light collection element of the secondary light sources is either a collector mirror surrounding each of the sources, or a collimator of light transmitting material.
  • These collimators have a known operating mode, for example from the patent US 2006 - 0239020 , equivalent to the patent EP 1 715 245 on behalf of Valeo Vision.
  • An improvement to the known design is to further provide that its front surface is convex or concave, while in known systems it is generally flat. It can also be at least partially diffusive, be structured, be provided with diffractive means ].
  • the main light beam coming from the main light source is a cut-off beam, in particular of the motorway code / complementary code type, in particular complementary to a code or road beam emitted by one or more other optical modules of the same projector .
  • the secondary light beam coming from the secondary light source or sources is a beam adding light above the main light beam.
  • the invention also relates to the projector incorporating an optical module described above.
  • the figures 3 (a perspective view) and 4 (a view from above) can represent these three LEDS.
  • only one secondary light source can be used: an LED is chosen which has a suitable, higher power. This single LED can also be placed above, sideways or below the main LED.
  • the three secondary LEDs according to the figures 1 , 3 and 4 are each attached to a not shown individual support and associated with a collimator of transparent material for collecting the light emitted by the LEDs.
  • FIG. figure 8 An example of a non-limiting form of collimator C is shown in FIG. figure 8 schematically: the collimator has the approximate shape in the form of "hat" or cone. It is a room full of revolution, with a FE light entry face which has an enveloping shape comprising a hollow delimited by two side walls PL and a bottom wall convex PF. The emitting surface of the LED is arranged facing / at least partly in this hollow.
  • the outlet face FS is slightly curved, convex, preferably cylindrical (alternatively, it could be flat). This specific form of the exit face makes it possible, in particular, to better spread the beam coming from the secondary LEDs coming out of the lens L
  • the secondary LEDs Ls1, Ls2 and Ls3 and their associated collimators C1, C2 and C3 are arranged above the main LED Lp. They are arranged in a ring, so that the light emerging from their collimators converges towards a mirror M of reference.
  • This mirror is flat. It is located in a plane inclined at 45 °, as the plane in which is arranged the main LED LP, plane shifted slightly forward with respect to the plane of the LED Lp.
  • This mirror M has a U-shape, with a notch appropriate so that it does not intercept (or almost no) the light emitted by the main LED Lp.
  • the Figures 3 and 4 represent for each of the secondary LEDs the drawing of a ray according to each of their main direction of emission: we see that these three rays converge towards the mirror M and that the mirror returns them to the lens L.
  • the mirror is a sheet (alternatively a plate of polymer material) covered with a layer of aluminum.
  • the layer has been deposited in such a way that it has a reflection coefficient of about 70% and a diffusion coefficient of about 30% (a ratio that can be broadly adjusted if necessary).
  • the modification of the diffusion coefficient can in particular be obtained by using surface texturing.
  • the mirror can also be streaked.
  • the figure 2 is a variant of the module according to figures 1 ; 3 and 4 : the plane p2 in which the mirror M is located is offset by an angle ⁇ of for example 5 or 10 ° with respect to the plane of the mirror p1 according to the figure 1 .
  • ⁇ for example 5 or 10 ° with respect to the plane of the mirror p1 according to the figure 1 .
  • the ray r'3 is represented with the mirror according to the initial inclination at 45 ° according to the plane p1, and r 2 with the mirror according to the inclination modified according to the plane p2: we see that r'3 comes out of the lens "higher” than r3.
  • the modification of the disposition, the inclination, the shape, the reflective / diffusing power of the mirror M make it possible to adjust the distribution and the general orientation of the light emitted by these secondary LEDs at the lens outlet, in accordance with the needs. very precise.
  • the mirror may indeed not be strictly flat, although this form is the simplest to achieve.
  • the mirror may also, for example, have a curved surface, convex or concave: It can be judiciously deformed to adjust the secondary beam.
  • the figure 5 is a representation of the module, seen from the outside of the module: we see the lens that closes the module forward, the three support plates Sp of the three secondary LEDs in the upper part, and the inclined plane p1 according to which the mirror M is arranged: it is seen that it has been possible to add secondary LEDs and their optical means associated with the initial module, without the size of the module being substantially increased, and without interfering with them. optically with the beam emitted by the main LED LP. (the possible means of cooling of the type radiators of the LEDs have not been represented).
  • each secondary LED, as shown Ls1, is no longer associated with a collimator, but a reflector R in one or more parts, which envelops the cone of light emitted by the LED to return it to the lens L.
  • the reflector R may further be provided with ridges.
  • the individual reflectors R directly direct the light of the secondary LEDs to the lens L.
  • the figure 7 is an alternative embodiment: in this simplified representation of the module, the secondary LEDs are not arranged above, but on one side of the main LED LP. And the deflection mirror M is then arranged opposite the cones of light emitted by the secondary LEDs via their collimators or individual reflectors.
  • the figure 12 is a schematic representation of such a module, whose main optical elements are of the type described in FIG. figure 4 of this patent, to which reference will be made for further details.
  • the main LED LP, a mirror M and a reflector RF paraboloid type are represented.
  • the diode LP is disposed in a substantially horizontal plane, in front of the RF reflector. It is preferably provided with a transparent element, in the form of a dome or not.
  • the mirror M is a plane mirror which gives the LP diode a virtual image which constitutes the light source for the RF reflector.
  • a secondary LED Ls1 has been added according to the invention, arranged so that its emitting surface sends at least a portion of the light that it emits to the mirror M.
  • the mirror M thus returns to the reflector RP at a time light emitted by the main LED LP and the secondary LED Ls1.
  • the reflector RP redirects the received light to the front of the module. So here we have a configuration where an optical element, the reflecting mirror M, is common to the main function and the secondary function.
  • the figure 14 is a variant of the module according to Figures 12 and 13 : the difference lies in the arrangement of the secondary LED Ls1: here, it is arranged behind the main LED LP and in an oblique plane and provided with a collimator C.
  • the system thus collects more light from Ls1 than in the previous configuration.
  • the figure 14 represents the two-ray paths from LP: Ip1 and Ip2, and the two-ray path from Ls1: Is1 and ls2. It is seen from these ray paths that the light from Ls1 has a tendency, at the output of the module, to have a rising direction.
  • the figure 15 is a representation of the isolux of the superposition of the road beam of the previous xenon elliptical module, of the highway code beam made with LP, and of the secondary beam obtained with the LED Ls1: the LED Ls1 adds light above the dome of the road in the Zi area.
