    OPTICAL PART COMPRISING A BLOCK WITH A BENDING DIOPTER FOR TWO BEAMS
    The present invention relates to the field of light devices, in particular of a motor vehicle, emitting different light beams from the same optical module.
    Light beams with different light functions are often produced by different optical modules. The disadvantage is the bulk in the vehicle and having a different light signature depending on the beam illuminated. This is for example the case when passing from a passing beam to a driving beam, or vice versa.
    The passing beam emits a road lighting beam having a cut-off above which almost no beam is sent, making it possible to avoid dazzling of vehicles being followed or coming in the opposite direction. This cut has in particular left-hand circulation a horizontal portion located at 0.57 degrees (0.57 °) below the horizon.
    If there is no risk of dazzling, the vehicle goes into a long-range beam or a road beam which illuminates above the horizon and is cut-off, thus making it possible to illuminate at a much higher range than the passing beam.
    There are nevertheless optical modules allowing, thanks to a tilting cover, to alternately perform a passing beam function or a driving beam function with the same light source and the same output diopter.
    However, such systems require at least one actuator and a specific mechanical device.
    A technical problem which the present invention aims to solve is therefore to produce an optical module making it possible to perform the two lighting functions, one of which is cut-off and one without cut-off or cut differently, this module having the same light signature for these two functions, while simplifying the mechanisms for passing from one function to another.
    To this end, a first object of the invention is an optical part comprising a block formed of a single first transparent or translucent material, this block comprising:
    a first collimator and a second collimator opposite each of which are intended to be positioned respectively a first and a second light sources, so that the light beams of these sources, respectively first and second beams, enter the block through an input diopter of these collimators, the collimators being arranged so that these sources can be positioned in the same plane;
    an intermediate output diopter towards which the first collimator guides the first beam so that this first beam leaves the block through this intermediate diopter,
    a cut-off diopter forming a folder with respect to this first beam and having a cut-off edge, the first collimator and the intermediate diopter being arranged so as to converge the first beam outside the block at this cut-off edge, the second collimator and the optical part being arranged so as to converge the second beam inside the block at the same cutting edge, the folder also forming a folder with respect to this second beam, the first and the second beams then propagating towards an exit of the optical part.
    It then suffices to have a first and a second light source respectively opposite the first and second collimators, as well as a projection system downstream of the folder and to arrange it to project the image from the cutting edge. This makes it possible to create two complementary beams on either side of a cut-off line, which can be generated alternately or together, depending on whether one turns on one or the other light sources or whether they are turned on together. The cut line corresponds to the image of this cut edge.
    With a block of the same material from the same optical part, it is therefore possible to perform two lighting functions, one with cut-off, in particular a passing beam, and one without, in particular a driving beam. This allows in particular to gain in compactness and to have the same signature.
    In addition, there is no need for an actuator and a mechanism for switching from one beam to another, since it is the switching on or off of one of the light sources which makes it possible to pass from 'one function to another.
    Furthermore, the mechanical arrangement of the light sources is simplified. They can in particular be arranged on the same flat support, which can be removed or assembled as a unit.
    The optical part therefore makes it possible to simplify the arrangement of the optical module in which it will be mounted.
    The optical part according to the invention can optionally comprise one or more of the following characteristics:
    the folder operates in total internal reflection; the manufacture of the optical part is faster because there is no step of aluminizing the folder;
    the block includes a recess comprising a surface forming the intermediate diopter and a surface forming the folder; this allows the dioptres to be produced during molding of the optical part;
    the block includes:
    o a portion forming a primary optic extending between a first and a second end, o a return diopter arranged with said intermediate diopter and the folder between said first end and said second end, the optical part being arranged so that the folder reflects the first beam on the return lens, so that the first beam enters the block again through the return lens, before propagating towards the exit of the optical part;
    the withdrawal comprises a surface forming the diopter back ; the diopter back may be tilted towards 1'amont starting boron i cutoff; we decreases the risk interference diopter back with thesecond beam; the distance between the diopter of back and the diopter
    intermediate increases by moving away from the bottom of the recess, this bottom being formed by the folder; this facilitates the release of the part from the mold;
    the optical part has a projection portion, forming a projection system arranged on the one hand downstream of the cutting edge so as to receive the first and second beams after their passage over this cutting edge and on the other hand, so as to project at the output of the projection portion an image of the cut edge; thus a clearer cut-off line is produced in the first and second beams.
    The invention also relates to a light module comprising an optical part according to the invention.
    This module can also include a projection system arranged on the one hand downstream of the cut-off edge so as to receive the first and second beams after their passage over this cut-off edge and on the other hand, so as to project at the outlet of the light module an image of the cut edge.
    In this application, a light module, also called an optical module, is the assembly which, from the rays initially originating from at least one light source, forms a functional light beam, namely the beam which illuminates a surface external to the device. light intended to contain the light module or which is seen from outside the light device.
    The optical part and / or the light module according to the invention can optionally include one or more of the following characteristics:
    the projection system is a piece or a piece piece piece made of transparent or translucent material, comprising:
    o a return diopter downstream and facing the cutting edge, o a terminal diopter forming the output of the projection system, the return diopter being arranged to reflect the first and second beams towards this diopter terminal, the return diopter and the terminal diopter being arranged so that the first and second beams are refracted by the terminal diopter and so as to project an image of the cutting edge; the positioning of the return diopter and of the intermediate diopter is thus carried out from the manufacture, in particular by molding, of the projection system;
    the folder extends in a plane forming an angle greater than or equal to 90 ° with a plane along which the return diopter extends generally; this makes it possible to arrange a first portion of the optical part more vertically, by having an emission of the functional light beam along an approximately horizontal overall axis, thereby reducing the depth requirement of the optical part and / or of the light module;
    the reference diopter operates in total internal reflection;
    at the output of the projection system, the second beam forms a passing beam having an upper cut line image of the cut edge and the first beam forms an upper part of the driving beam having a lower cut line image of the cut edge; thus the upper and lower cut-off lines are complementary and a road beam or a part of the road beam can be formed by lighting the first and the second light source.
    The invention also relates to a vehicle light device, in particular a vehicle headlight, comprising an optical part and / or a light module according to the invention.
    The invention also relates to a vehicle comprising a vehicle light device according to the invention, in particular connected to the electrical supply of the vehicle.

    FIG. 8 represents a light module with an optical part according to a second exemplary embodiment.
    Figures 1 to 3 illustrate an embodiment of an optical part 1 according to the invention.
    This optical part 1 comprises a block 2 formed from a single first transparent or translucent material, for example obtained by molding.
    This block 2 comprises a first collimator 11 and a second collimator 12, each having light entry diopters in this block 2.
    As illustrated in FIG. 4, a first light source 21 is placed facing the input diopter of the first collimator 11, so that the light beam from this source 21, hereinafter first beam F1, enters block 2 through this input diopter. In particular the majority, even all of its light rays, enter block 2 through this input diopter.
    Also, a second light source 22 is placed facing the input diopter of the second collimator 12, so that the light beam from this source 22, hereinafter second beam F2, enters the block 2 through this input diopter. In particular the majority, even all of its light rays, enter block 2 through this input diopter.
    These first and second collimators 11, 12 are arranged so that the first and second light sources 21, 22 can be positioned in the same plane. Thus, these sources 21, 22 can in particular be arranged on the same flat support, such as an upper radiator surface or, as here, on a flat printed circuit board.
    According to the invention, as in the example illustrated, the block 2 may comprise a portion forming a primary optic 3 extending between a first end 3a and a second end 3b. The first and second collimators 11, 12 are arranged at the end of the first end 3a.
    Here, the optical part 1 has a projection portion 4, forming a projection system joined in one piece with said second end 3b. In other words, the primary optics 3 and the projection portion 4 here form the block 2.
    A recess 30 is placed, here back, between said first end 3a and said second end 3b. This withdrawal 30 is arranged so that the diopters 31, 32, 33 delimiting this withdrawal 30 form means for producing a lower cut-off line of a beam and an upper cut-off line of another beam , these cut-off lines being complementary.
    Here, a first diopter 31, hereinafter intermediate output diopter 31, delimits the bottom of the recess 30. It is here generally horizontal.
    This first diopter 31 is followed by a second diopter, hereinafter cut-off diopter or folding machine 32. The latter delimits the withdrawal 30 in front and therefore forms its bottom, the withdrawal 30 being open towards the rear.
    The second diopter 32 is followed by a third diopter 33, hereinafter return diopter 3.
    The folder 32 joins with the return diopter 33 at a cutting edge 32c.
    Here the folder 32 comprises two substantially flat sections 32a, 32b and forming between them an angle corresponding to the angle between an oblique portion and a horizontal portion of a cut line of a passing beam, ie approximately 15 °.
    The projection portion 4 includes:
    a reference diopter 40 above and facing the cutting edge 32c.
    a terminal diopter 41 forming the outlet of the projection portion 4.
    According to the invention, as here, the return diopter 40 and the terminal diopter 41 can form a convergent system with a focal plane, so that the cutting edge 32c is arranged in this focal plane.
    Here, the sides 32a, 32b of the folder 32 extend in a plane forming an angle greater than or equal to 90 ° with a plane along which the return diopter 40 extends overall.
    FIG. 4 schematically illustrates the path of the first light beam F1, the rays of which are represented by dotted arrows and the point of which ends in two segments. Also shown is the path of the second light beam F2, the rays of which are represented by arrows in solid lines and the point of which ends in a triangle. These paths are illustrated from their emission from the light sources 21, 22, to their emission out of the optical part 1 through the output 41.
    The arrangement of the optical part 1 here allows the ray paths described below.
    The first collimator 11 deflects the first beam F1 towards the intermediate diopter 31, so that this first beam leaves, by refraction, from the block 2 through this intermediate diopter 31, and thus enters the withdrawal 30.
    Thanks to the layout of first collimator 11 and of intermediate diopter 31, the first beam fl converges at outside of block 2, in the withdrawal 30, towards and sure the edge 32c. In a general way himself Ion the invention, as here, the projection system 4 can to be focused on the edge of
    break 32c.
    Thus, the rays of the first beam F1 passing at the cutting edge 32c then reach the return diopter 40, which then reflects these rays towards the terminal diopter
    41, from which the rays emerge by refraction parallel to the optical axis A.
    On the other hand, the rays of the first beam F1 passing behind the cut-off edge 32c re-enter again into block 2 through the return diopter 33 and reach the return diopter 40, which then reflects these rays towards the terminal diopter 41, from which these rays emerge by refraction more inclined upwards relative to the optical axis A.
    Likewise, the rays of the first beam F1 which meet the bending machine 32 are reflected towards the return diopter 33 and therefore return by refraction again to block 2, passing behind the cutting edge 32c. The first beam F1 is therefore well reflected, here in part, towards the return diopter 33 by the folder 32. As for the rays mentioned in the previous paragraph, the rays reflected by the folder 32 reach the return diopter 40, which then reflects these rays towards the terminal diopter 41, from which these rays exit by refraction more inclined upwards relative to the optical axis A.
    Thus, the first beam F1 forms an illumination beam having a lower cutoff line C1, image of the cutoff edge 32c. This lighting beam is represented diagrammatically in FIG. 5, in projection on a vertical screen substantially perpendicular to the optical axis A, for example located at 25 meters.
    As can be seen in Figure 5, the cut line C1 has a horizontal portion C '1 and an oblique portion C''l, corresponding to the shape of the cut edge 32c. The angle between these two portions C '1 and C' '1 corresponds in fact to the angle that the two sides 32a, 32b of the folder 32 make between them, and therefore to the angle presented by the cutting edge 32c .
    The rays which were likely to pass in front of the cutting edge 32c have therefore been returned back by the second diopter 32 of the recess 31 and therefore complete the beam Fl. The second diopter 32 therefore forms a folder for the first beam Fl, from outside the block.
    The second collimator 12 deflects the second beam F2 so as to make it converge inside the block 2 towards and on the cutting edge 32c.
    The projection system 4 being focused on the cutting edge 32c, the rays of the second beam F2 passing at the cutting edge 32c then reach the return diopter 40, which then reflects these rays towards the terminal diopter 41, from where the rays exit by refraction parallel to the optical axis A.
    On the other hand, the rays of the second beam F2 passing in front of the cutting edge 32c re-enter again into block 2 and reach the return diopter 40, which then reflects these rays towards the terminal diopter 41, from which these rays refract more inclined downward with respect to the optical axis A.
    Likewise, the rays of the second beam F2 which meet the folder 32 are reflected directly or indirectly towards the return diopter 40 passing in front of the cutting edge 32c. As for the rays mentioned in the previous paragraph, the return diopter 40 then reflects these rays towards the terminal diopter 41, from which they exit by refraction more inclined downward relative to the optical axis A.
    Thus, the second beam F2 forms an illumination beam having an upper cut line C2, image of the cut edge 32c. This lighting beam is represented diagrammatically in FIG. 6, according to the same projection as in FIG. 5.
    As can be seen in FIG. 6, the cut line C2 has a horizontal portion C'2 and an oblique portion C''2, corresponding to the shape of the cut edge 32c. The angle between these two portions C'2 and C''2 corresponds in fact to the angle which the two sides 32a, 32b of the folder 32 make between them, and therefore to the angle presented by the cutting edge 32c .
    The rays which were liable to pass behind the cut-off edge 32c have therefore been returned forward by the second diopter 32 of the recess 31 and therefore complete the second beam F2. The second diopter 32 therefore forms a folder for the second beam F2, from inside the block 2.
    Two complementary beams F1 and F2 are thus created on either side of a cut-off line, which can be generated alternately or together, depending on whether one turns on one or other of the light sources 21, 22 or that we turn them on
    together. So in figure 7, we can see the beam total F T obtained in generating in same time the first beam fl and the second beam F2 Cl cut lines, C2 are contiguous and shown here in dotted lines.
    For example, the second beam F2 can form a passing beam, as illustrated here, or a central portion with the oblique cutoff line of a passing beam. This portion is then superimposed in addition to a lower portion of the low beam. The total beam F T can form a driving beam for it, as in FIG. 7, or, in the second case, the central portion of the driving beam.
    The folder 32 and the return diopter 40 operate here in total internal reflection.
    Note that here the withdrawal 30 is "empty", in the sense that it is filled with ambient gas, air, contained in the light device equipped with the light module 10. Alternatively, the withdrawal 30 can be filled with a second transparent or translucent material with an optical index different from that of block 2.
    Alternatively, the folder 32 and the deflection diopter 40 can be covered outside the block 2 with a reflective coating, such as an aluminizing coating.
    Here the primary optics 1 and the projection portion 4 have been shown in a single piece.
    However, according to a variant not shown, they could be made in two separate parts. The optical part according to the invention would in this case be formed by the primary optics.
    According to the preceding paragraph, the optical part may not include a return diopter, the part forming the projection system being able to be arranged so as to collect directly the rays emerging from the intermediate diopter or reflected by the folder outside the block, and those leaving the block after guiding in the block by reflection on the folder and / or the walls of the primary optics or even coming directly from the second collimator.
    According to a variant not shown, the withdrawal can be used so that the spokes passing through it produce one or a portion of a passing beam, while the portion or portion of the driving beam is produced by the spokes remaining in the block . For example, with respect to the example illustrated, the withdrawal would be arranged at the front of the primary optic 3 and would open towards the front.
    In general according to the invention, as illustrated, the light sources 21, 22 can be light-emitting diodes, also called LEDs (for “Light Emitting Diode” in English).
    FIG. 8 illustrates a second embodiment, where a module 110 with a massive optical part is produced.
    This optical part comprises a first elementary portion 101, which is equivalent in arrangement to the optical part 1 described above, except that it does not in itself form an optical part. In particular, its collimators 111, 112, its withdrawal, with its three diopters 132, 132, 133, and its return diopter 140 are arranged in the same way and will not be described further.
    Here the massive optical part also comprises six second elementary portions, the collimators, the folders and the reference diopters of which are respectively referenced 212, 232 and 240. These second elementary portions differ from the first 101 in that their folder 232 are completely flat . They indeed make it possible to participate in the formation of the horizontal cut-off of the passing beam over its entire width, when the second corresponding beams are emitted, as well as to cover the width of the driving beam, when the first corresponding beams are emitted.
    The first elementary portion 101 is located on one side of the second elementary portions, which they are adjacent to each other. On the other side, a third and a fourth elementary portions are arranged, similar to the first portion 101.
    In Figure 8, given the perspective, we can observe the second collimators 312, 412 as well as the reference diopters 340, 440 of these third and fourth elementary portions. On the other hand, only the first collimator and the folder 332 of the third portion are visible, those of the fourth portion being hidden.
    These third and fourth elementary portions also make it possible to produce central portions with oblique cutoff in order to complement the intensity formed by the first portion 101.
    An exit diopter 141, here with a smooth surface, is arranged opposite all the return diopters 140, 240, 340, 440 and forms with these the projection system of each of the elementary portions.
    Note that in FIG. 8, for reasons of clarity, only the collimators 111, 112, 212, 312, 412, the withdrawals, the return diopters 140, 240, 340, 440 and the output diopter 141 are shown. The surfaces joining them together are not shown. However, this is a massive one-piece piece.
    The elementary portions can be joined laterally between them, the various collimators and diopters allowing the majority, even all of the rays to remain in the elementary portion where they are initially returned.
    As a variant, the elementary portions may form separate light guides joining in a single monobloc piece only at the level of the projection system or between the reference diopters and the output diopter 141.
    It is nevertheless possible to make each elementary portion individually and to fix and then adjust them together in the light device.
