    [0001] The present invention relates to a light module for a headlight of a motor vehicle comprising at least one light source and an optical element for generating a light beam with a cutoff. partly oblique; in particular this optical element can be used to generate a beam with an oblique cut to the left or to the right depending on the type of regulation to which the vehicle is subjected.
    [0002] Vehicle lighting systems are subject to different types of regulations depending on the country in which the vehicle is approved. In particular, in countries where the right-hand side of the carriageway is driven (traffic on the right), the illumination of the dipped beams, or coded beam, is shifted to the right by 15 ° in order to illuminate traffic signs and sidewalks or aisles. Conversely, in countries where you drive on the left side of the road (traffic on the left), as in the United Kingdom, the cut of the code beam is raised to the left. In the case of a module whose structure is simple, the compatibility between the traffic on the right and the traffic on the left can be solved by the addition of another specific module if this does not imply an excessive cost. In the case of a more complex module, the cost of duplication can become prohibitive. Different vehicle lighting systems adaptable to traffic on the left and right exist. In particular, the patent application US2008 / 0002420A1 describes a configurable system according to the country's regulations. The projector, intended to generate the desired configuration, may comprise two different modules and inclined in an opposite manner. These two modules are then selectively illuminated to generate the configuration corresponding to the country's regulations. The projector can also have only one module, this module then being mobile. Just turn it to the required inclination. This mobile mechanism is driven by a controller.
    [0003] These two configuration change embodiments are not optimized, neither in terms of size nor in terms of cost. The first example requires two modules, only one being used at a time. The second example requires a controller.
    [0004] There is therefore a need for an optical module that is compatible with both right-hand traffic and left-hand traffic and that overcomes the above disadvantages. The invention proposes a light module for a motor vehicle comprising an optical element intended to generate a beam with a cut in part oblique, the optical element comprising at least one optical portion having an optical axis, and at least one light source configured to cooperate with said portion, characterized in that the optical module comprises at least two distinct positions to have a light source for generating at least the portion of the beam 15 comprising the oblique cutoff, the light source occupying one of the two positions, each of the positions being defined on either side of the optical axis of the optical portion so as to generate an obliquely cut beam to the right in the first position and an obliquely cut beam to the left in the second position.
    [0005] In this way, the same optical module can be used for the traffic on the left and for the traffic on the right. Therefore, the manufacturer of the projector must only design a single optical element, with unique manufacturing tools (molds for example), to produce a single optical module compatible with different types of traffic. The beam 25 advantageously comprises at least one horizontal cutoff portion followed by an oblique cutoff portion, in particular inclined at an angle of 15 ° or 45 °. On the other hand, the light module according to the invention can be a lighting and / or signaling module. Preferably, the optical element comprises at least one input surface and at least one output surface provided with a focus, said input surface being located substantially in a plane comprising said focus.
    [0006] Advantageously, the first position is to the left of the optical axis of said portion and the second position is to the right of the optical axis of said portion at the input surface of the optical element. Advantageously, the two positions of the light source 5 are defined in a vicinity of the focus of the outer surface. Preferably, the distance between the two positions is substantially equal to F tan (1.3 °), F being the thickness of the corresponding elementary portion. Advantageously, the orientation of the light source in the first position is between 10 ° and 45 °, preferably between 15 ° and 30 °, in particular equal to 15 °, with respect to a horizontal axis and the orientation of the source in the second position is between -10 ° and -45 °, preferably between -15 ° and -30 °, in particular equal to -15 °, with respect to a horizontal axis.
    [0007] Preferably, the light source consists of a semiconductor chip emitting a light, for example a light-emitting diode. Advantageously, the light source is a light emitting diode comprising at least one light emitting element whose orientation of the edges of the light emitting element depends on the angle of the oblique cut. Preferably, the optical portion is a lens. Advantageously, the material of the optical portion is PVC, glass, polycarbonate or PMMA (Polymethyl methacrylate) or silicone. Advantageously, the outer surface of the optical portion is substantially an ellipsoid portion. Preferably, the ellipsoid portion is obtained by deforming an ellipsoid of revolution in a homothetic manner with respect to a plane to generate an obliquely cut beam to the right in the first position and an oblique cut beam to the first position. the left in the second position. Advantageously, the optical module further comprises a substrate, which substrate has at least one surface intended to receive a light source. The invention also relates to a light projector for a motor vehicle comprising at least one optical module according to the invention. Advantageously, a light projector according to the invention comprises: a housing intended to be fixed on a vehicle; a closing window of said housing, said light projector (1) being housed inside the space delimited by the housing and the closure glass, the light projector being arranged so that the rays issuing from said exit surface directly reach said closing window. Preferably, the rays emitted by the module at the output of the overall output surface of the module form a portion or the entirety of a lighting beam of the road, signaling, or lighting of the passenger compartment.

Referring to FIG. 1, a light module 1 according to the invention 10 comprises a heat sink 2 connected to a substrate 3, an electronic card 4, of the printed circuit board type, provided with an electrical connector 5, five diodes electroluminescent 6 which will be called LED (Light Emitting Diode in English) for the following description, an optical element 7 in transparent material according to the invention and a housing 8 of 15 protection and maintenance, adapted to grip the element 7. The housing 8 is for example fixed to the substrate 3 by means of a first series of screws 9. The electronic card 4 is for example anchored in the substrate 3 by means of a second series of screws 10. The substrate 3 further comprises five locations 6a for positioning the diodes 6. Such a module 1 is intended to be fixed, for example, inside a vehicle headlamp. Referring to Figure 2, the optical element 7 of transparent material according to the invention is full and is made for example of PMMA (polymethyl methacrylate), and plays the role of an optical lens. This optical element schematically comprises two lateral lugs 11, 12 and 25 a central body 13 situated between the lugs 11, 12. The body 13 is bordered by two end arms 14, 15, each connected to a lug 11, 12, each arms 14, 15 extending in a direction which is perpendicular to that of the lug 11, 12 to which it is connected. The two lugs 11, 12 are strictly aligned, so that the optical element 7 can bear against a flat surface, via its lugs 11, 12. The body 13 of this optical element 7 is divided into five elementary portions 16, 17, 18, 19, 20 full, each characterized by an inlet surface 21, 22, 23, 24, 25 and an outlet surface 26, 27, 28, 29, 30. This Optical element 7 thus has two elementary end portions 16, 17 forming the two end arms 14 and 15 and three intermediate elementary portions 18, 19, 20 positioned between end portions 16 and 17. . The five exit surfaces 26, 27, 28, 29, 30 are contiguous to form an overall exit surface of the optical element 7, which is continuous. The five inlet surfaces 21, 22, 23, 24, 25 are separated from one another, and are substantially aligned with the two legs 11, 12. Each portion 16, 17, 18, 19, 20 is elongate, inlet surface 21, 22, 23, 24, 25 and the outlet surface 26, 27, 28, 29, 30 constituting the two ends of each of the portions 16, 17, 18, 19, 20 along their longitudinal axis. . The three intermediate elementary portions 18, 19, 20 each have two walls 31, 32, 33, 34, 35, 36 originating at the inlet surface 23, 24, 25 and extending towards two edges delimiting the outlet surface 28, 29, 30 of the same portion 18, 19, 20. These walls 31, 32, 33, 34, 35, 36, which may for example be aluminized, are intended to prevent the beams produced by a light source positioned at an inlet surface 23, 24, 20 of a portion 18, 19, 20, to pass through the exit surface of an adjacent portion. The two elementary end portions 16, 17 have only one wall 37, 38 intended to prevent a light source placed at the level of the input surface 21, 22, of one of them, to irradiate an exit surface of an adjacent elementary portion, since each of the end portions 16, 17 has only one adjacent elementary portion. The walls 31, 32, 33, 34, 35, 36, 37, 38 of two elementary portions 16, 17, 18, 19, 20 adjacent meet by means of a curved wall segment. The optical element 7 thus has a series of four recesses 39, 40, 41, 42 alternately aligned with the five elementary portions 16, 17, 18, 19, 20, 30, each recess being delimited by a wall of a portion elementary and by a wall of an adjacent elementary portion. The two input surfaces 30, 22, 22 of the two end elementary portions 16, 17 are set back from the input surfaces 23, 24, 25 of the three intermediate elementary portions 18, 19, 20. For each of the five elementary portions 16, 17, 18, 19, 20, the average distance between the entrance surface and the exit surface is substantially constant. The inlet surfaces 21, 22, 23, 24, 25 are planar and the outlet surfaces 26, 27, 28, 29, 30 are rounded in shape. Preferably, each exit surface (26, 27, 28, 29, 30) of a portion (16, 17, 18, 19, 20) has a focus that is substantially at the entrance surface (21). , 22, 23, 24, 25). The shape of each exit surface is substantially that of an ellipsoid portion. The fact that the focus of each exit surface is at the entrance surface of the same portion means that there is a point or segment, horizontal or inclined, in the vicinity of the entrance surface such that a majority of the rays issuing from this point or points of the line emerge from the exit surface while being parallel to the same plane. Referring to Figure 1, the radiator 2 and the substrate 3 constitute a single piece optical element preferably of metal. The substrate 3 is comparable to a thin plate having an implantation face 43 having a recess 44 whose contour is similar to that of the electronic card 4, the recess 44 being intended to receive the card 4. This face 43 has a central protrusion 45 partially bordering the recess 44 and contributing to partially enlarge the edge surrounding the recess 44. Referring to Figure 1, the five LEDs 6 are secured to the face 43 of the substrate 3, which is provided with the recess 44, at an area outside the recess 44. More specifically, with reference to FIG. 1, the five LEDs 6 are arranged along the edge delimiting the recess 44, three LED 6 being placed on the protuberance 45 and the other two LEDs 6 being placed at the level of the face 43 of the substrate 3 located at a lower altitude than that of the protrusion 45. In this way, two LEDs 6 of extremity flank three LED 6 intermediate, raised. Each LED 6 has a photoemissive element of substantially square shape and having a small thickness.
    [0010] The five LEDs 6 are rotated differently with respect to the forward direction, ie the transmission direction of the module. In other words, in front view, these LEDs have different orientations. For example in projection on a projection plane located in front of the LEDs and perpendicular to the optical axis of emission of the light module, these LEDs have different orientations within the projection plane. Thus, two LEDs can be arranged so that the edges of their light emitting elements present, in front view, a different orientation. These edges can, in front view, make between them an angle of 45 °. This angle makes it possible to reduce the thickness of the beam, the beam being thicker when the LED is vertical and finer when it is horizontal. An angle of 45 ° between the edges of the photoemissive elements of the two LEDs also improves the homogeneity of the beam, without changing its light distribution which is always horizontal. These five LEDs 6 are arranged to emit a light beam in the same direction.
    [0011] As illustrated in FIG. 1, the optical element 7 according to the invention is fixed on the substrate 3 so that each of the five LEDs 6, secured to the substrate 3, comes to be positioned at a surface d input 21, 22, 23, 24, 25 of the optical element 7, illustrated in FIG. 2, so that each LED 6 can send a light beam to the input surface 21, 22, 23, 24, To which it is associated, the beams passing through the inlet surface 21, 22, 23, 24, 25 to then pass through the outlet surface 26, 27, 28, 29, 30 of the same portion. Thus, the light beams from each input surface 21, 22, 23, 24, 25 can either directly reach the corresponding exit surface 26, 27, 28, 29, 30, or be previously reflected on the walls. 31, 32, 33, 34, 35, 36, 37, 38 before reaching the exit surface. The walls 31, 32, 33, 34, 35, 36, 37, 38 prevent the light beams emitted by an LED 6 placed at an elementary portion 16, 17, 18, 19, 20, to reach the exit surface 26, 27, 28, 29, 30 of an adjacent elementary portion. The elementary portions 16, 17, 18, 19, 20 act separately and autonomously, in order to obtain a resulting light beam, without parasitic interference. FIGS. 3A to 6B illustrate an example of use of a light module 1 according to the invention, by decomposing the resulting light beam, into several components, each of which comes from an elementary portion 17, 18, 19, 20, of the module 1 associated with the corresponding LED 6. The light beam from the end portion 16 is illustrated in FIGS. 9A, 9B and 11A, 11B. In this way, referring to FIGS. 3A and 3B, the end elementary portion 17 located to the left of the module 1 and associated with the corresponding end LED 6 can be used to produce a leftward illumination focusing on the scope. This lighting is rather concentrated and intense. Referring to FIGS. 4A and 4B, the left intermediate elementary portion 20, associated with the corresponding LED 6, can be used to produce extended illumination horizontally to the left. This lighting is rather low intensity and spread transversely to the vehicle. Referring to FIGS. 5A and 5B, the central intermediate elementary portion 19, associated with the corresponding LED 6, can be used to produce horizontally extended illumination to the right as well as to the left. This lighting is rather low intensity and spread transversely to the vehicle. Referring to FIGS. 6A and 6B, the right intermediate elementary portion 18, associated with the corresponding LED 6, can be used to produce extended illumination horizontally to the right. This lighting is rather low intensity and spread transversely to the vehicle. The lights generated by the portions 17, 18, 19 and 20 are extended horizontally. They are dedicated to illuminate the road facing the driver. These last 5 can be used in particular to generate a portion of the lighting required by the dipped beam of a vehicle. The different lighting distributions illustrated in FIGS. 3B to 6B show that these components comprise a horizontal cut, ie there is no light beyond the line indicating the horizontal on the isolated diagrams of the light beam. The crossing lights generally also include a component having an oblique cut to illuminate the panels located on the side of the road, as well as sidewalks or aisles. This oblique cut forms an angle with the horizontal cut of the other components illustrated in Figures 3B-6B. The angle formed by this oblique cut is preferably + 15 degrees (oblique right side of the beam, raised upwards) for cars designed for traffic on the right, and this angle is preferably -15 degrees (oblique part to left of the beam, raised upwards) for cars designed for traffic on the left.
    [0012] The end elementary portion 16 is dedicated to providing illumination having an oblique cut compatible with the traffic on the right and the traffic on the left. The input surface 21 of the elementary portion 16 has two distinct positions for disposing an LED for generating illumination 25 comprising the oblique cutoff. Each of the two positions is defined on either side of the optical axis of the elementary portion 16. It is the position of the source relative to the optical axis which determines the direction of propagation of the rays. In the first position, the LED generates an oblique cut-off light to the right, and in the second position, the LED 30 generates an oblique cut-off light to the left. It is an intense lighting focusing on the scope.
    [0013] 303 2 5 1 4 14 Figure 7 illustrates the change of position of the LED 6 to move from the first position to the second position. The optical axis of the elementary portion 16 is perpendicular to the lines 50 and 51, so as to be perpendicular to the LED 6. The photoemissive element of the LED 6 is first rotated about its axis 61 (the trace the axis, coinciding with the center of the LED, is indicated by 61) in order to correctly orient the distribution of the beam on the road according to the traffic. It is then translated to the right so that the beam propagates to the left. In the first position, the center of the LED 61 is positioned to the left of the optical axis 50 to the left of the optical axis, at a distance F tan (1.3 °) of the latter, where F is the the thickness of the elementary portion 16. The photoemissive element of the LED is inclined relative to the horizontal axis 51. Preferably, the photoemissive element forms an angle of 15 degrees with the horizontal. Preferably, the amplitude of the rotation to move from the first position to the second position is 150 ° so that the angle formed by the edges of the light emitting element with the horizontal 51 is -15 °. Finally, to arrive in the second position, the LED is translated so that its center is to the right of the optical axis of the elementary portion 16.
    [0014] The two positions make it possible to obtain beams with oblique cut substantially symmetrical. These two positions are located in the vicinity of the focus of the outer surface 26. The first position is substantially shifted to the left of the focus and the second position is substantially shifted to the right of the focus. The fact that the two positions are close to each other ensures that the optical module is compact. The shape of the exit surface 26 of the elementary portion 16 makes it possible to obtain the two oblique cut beams respectively to the right and to the left for each of the positions of the LED. The shape of the exit surface 26 is substantially that of an ellipsoid. A ray tracing software is used to determine the necessary changes to the ellipsoid of revolution to generate the obliquely cut beams corresponding to each of the positions. The ellipsoid of revolution is homothetically deformed with respect to a plane in order to generate an obliquely cut beam to the right in the first position and an obliquely cut beam to the left in the second position. The deformation of the surface is made with respect to a direction perpendicular to a plane, which is obtained by: - a rotation of 20 ° in the trigonometric direction of the vertical plane around the optical axis of the optical portion 16, 10 - a translation of this plane by relative to the focus of the optical portion to the right. Figure 8 is a rear view of the elementary portion 16 with the LED 6 in the first position. The LED 6 is positioned on the input surface 21 to the left of the optical axis (not shown in the figure). It is inclined at an angle of 15 degrees to the horizontal axis 51. FIG. 9A illustrates the path of the light rays from the fifth diode 6 when the latter is in the first position on the input surface. 21. The diode is positioned to the left of the optical axis 50 and the beam is propagated to the right of the latter. Part of the beam is reflected on the wall 37. The distribution of the illumination is illustrated in Figure 9B. The beam has an oblique cut to the right. The angle of the cut is 15 ° to the horizontal. Figure 10 is a rear view of the portion 16 with the LED 6 in the second position. The LED 6 is positioned on the input surface 21 to the right of the optical axis (not shown in the figure). It is inclined at an angle of -15 degrees with respect to the horizontal axis 51. FIG. 11A illustrates the trajectory of the light beams coming from the fifth diode when the latter is in the second position on the input surface 21 The diode is positioned to the right of the optical axis 50 and the beam is propagated to the left of the optical axis 50. Part of the beam is also reflected on the wall 37. The distribution of the illumination is shown in Figure 11B. The beam has an oblique cut to the left whose angle of cut is -15 ° relative to the horizontal. Referring to FIG. 12, the optical element 7 is illustrated with the propagation of the light beam in the portion 16 at the right end 5 simultaneously for the two positions of the diode. The beam illustrated by dashed lines comes from the first position of the diode. The beam propagates to the right to generate oblique cut-off lighting to the right. Conversely, the beam illustrated by the dashes comes from the LED when it is in the second position, to the right of the optical axis. The beam propagates to the left to generate oblique cut-off illumination to the left. In this way, an identical mold will be used to produce the optical element 7 according to the invention. Only the position of the LEDs changes according to the type of traffic to which the motor vehicle will be subjected. However, as previously described, the five LEDs 6 are secured to the face 43 of the substrate 3. It is therefore sufficient to produce two types of substrates with LED positions adapted to the type of traffic. As clearly shown in FIGS. 3A, 4A, 5A, 6A, 9A and 11A, the light beams produced by each LED 6 of the light module 1, pass through only the elementary portion 16, 17, 18, 19, 20 to which the LED 6 is associated, without being able to go towards the exit surface 26, 27, 28, 29, 30 of an adjacent elementary portion 16, 17, 18, 19, 20. It follows that a light module 1 according to FIG. invention, is able to produce a resulting light beam, which is clear and precise, because devoid of any light beams 25 parasites due to light interference between the different elementary portions 16, 17, 18, 19, 20 of the module 1. Well that the LEDs all have the same reference in the description, in this case the number 6, they can naturally have different structural, geometrical and luminous characteristics within the same light module 1, the LEDs 6 being chosen in FIG. specific needs function s in lighting. Preferably, the optical source is a semiconductor chip emitting a light, for example an electroluminescent diode. Such a diode offers a good quality of light beam, while remaining a small size. It is therefore perfectly adapted to a light module according to the invention, whose dimensions must be limited to be, for example, incorporated in a motor vehicle.
    [0015] The type of source used in the present invention, however, is not limited to that of a light emitting diode. The source may also be an incandescent lamp, a discharge lamp, a laser source, or any type of source for generating a beam having properties similar to the properties described above.
    [0016] Although the lighting device according to the invention has been described in the context of a device comprising a plurality of optical portions, making it possible to generate all the components required by the low beam, this lighting device can also include only the elementary end portion 16. This isolated elementary portion 16 thus forms a separate optical module. The manufacturer of the projector must only design a single optical element, with unique manufacturing tools (molds for example), to manufacture a single optical module compatible with different types of traffic. Since it is the position of the light sources relating to the elementary end portion 16 which determines the type of oblique cut beam, the manufacturer of the projector can design two models of substrates 3 on which the light sources are positioned, one being designed for left-hand traffic and the second being designed for right-hand traffic.
    [0017] The optical module according to the invention has a compact geometry, and is therefore not bulky. Preferably, the rays emitted by the module at the output of the output surface of the module form a portion or the entirety of a beam 5 of road lighting, signaling, or lighting of the passenger compartment. In this way, it is not useful to put another optical deflection element or a cache. In other words, the light device may be devoid of a lens, reflector or cover after the exit surface. Although the light device according to the invention has been described in the context of an oblique cut beam, this device can also be adapted to other types of beams with oblique cut, requiring the same optics and different positions of the beam. light sources for generating respective light beams compatible with different types of regulations. On the other hand, the light module according to the invention may be a lighting and / or signaling module.
