    [0001] The present invention relates to a lighting module, in particular for a motor vehicle. The lighting module is bifunctional, that is to say it comprises a first code-type lighting function and, in addition, a second road-type lighting function, completing the code function. The car headlamps are often equipped with different modules, each module being dedicated to generate different types of lighting: high beam, low beam (also called code), fog lamps, etc. In order to limit the space requirement resulting from the arrangement of different modules within the same projector, and at the same time to reduce the associated costs, it is desirable to combine different modules and / or to reduce the size of the modules. within the same projector. In particular, the document US2011 / 0008753A1 describes a device for combining the functions relating to fog lights and dipped beam. To do this, the document proposes the use of two semiconductor elements emitting light, each element being selectively controlled to generate the type of lights required by the driver. This type of module allows the compatibility between the fog lamps and the dipped beam in a single module. However, it does not provide the two functions low beam and high beam. An object of the present invention is to integrate an additional lighting function with a module for generating a code beam.
    [0002] Preferably, the object of the present invention is to add the lighting function making the driving beam to the code beam module without having to increase its dimensions or add other mechanical elements. The invention proposes a lighting module, in particular for a motor vehicle, comprising an optical element intended to produce at least a first beam having a cut at least partly oblique, and at least a first light source, the module being characterized in that that the optical element comprises at least one optical portion having an optical axis and a focus, the first light source being disposed at the focus and able to emit first light rays to the optical element to produce the first beam, the module further comprises a second light source, the second light source being arranged at a distance from the focus and offset downwardly with respect to the first light source along a vertical axis, the second light source being able to emit second light rays towards the light source; optical element for producing a second beam illuminating at least partially above the cut.
    [0003] By oblique cutting part is meant an oblique cut-off portion with respect to the remainder of the cut. Advantageously, the first beam has a cut-off type of a crossing light. In this case, the first beam is intended to be part of a cross-type beam. Advantageously, the optical element is arranged to project, from the first light rays, a plurality of images of the first source so that the upper edges of these images are aligned and / or superimposed to form said oblique portion of the cut of the first beam.
    [0004] According to a feature of the invention, the second light source is vertically offset from the focal point by a distance such that a plurality of images of the second source formed by the projection of the second light rays by the optical element , are disposed at least partially above the cut of the first beam. Where appropriate, the second beam may have a complementary light beam type light distribution. Preferably, the second light source is shifted with respect to the first light source along a transverse axis so that the light beams are concentrated at the optical axis to form a light spot whose characteristics are those of a driving beam. For example, the second light source is shifted transversely to the focal point by a distance such that a plurality of images of the second source, formed by the projection of the second light rays by the optical element, are concentrated at level of the optical axis.
    [0005] Advantageously, the first light source has a light emission zone comprising an edge, this edge being disposed at the focus of the optical portion of the optical element. If necessary, the first light source can be oriented vis-à-vis the optical element so that said edge is an oblique edge.
    [0006] For example, the oblique edge extends with respect to a transverse axis of the optical element. Advantageously, the second light source is oriented vis-à-vis the optical element identically to the orientation of the first light source vis-à-vis the optical element.
    [0007] Preferably, a crossing-type beam comprising the first beam is generated when the first light source is on, the second light source being extinguished. Advantageously, a road-type beam comprising an overlap and / or a juxtaposition of the first and second beams is generated when the first and second light sources are on. Optionally, a diurnal-type beam is generated when the second light source is turned on while being powered with a lower electric power than that required to generate the second beam, the first light source being off.
    [0008] Preferably, the distance between the two light sources is less than or equal to a fraction of the focal length of the optical portion. For example, if f denotes said focal length, the distance between the two light sources may be less than or equal to rtan (0.57 °), ie about f / 100.
    [0009] Advantageously, the first and second light sources each consist of a selectively activatable semiconductor light emitting chip. For example, the first and second sources are formed by the same bipolar type electroluminescent diode. Alternatively, the first and second light sources are formed by a matrix of diodes having at least two diodes each forming one of the light sources. Preferably, the optical portion is a lens. Advantageously, the material of the optical portion comprises silicone, glass, polycarbonate or PMMA. Preferably, the first beam is intended to be part of a crossover type beam. Where appropriate, the optical element may comprise at least one second optical portion having an optical axis, a focus and a third light source disposed in the vicinity of the focus of the second optical portion to produce at least a second beam forming part of said beam of light. cross type.

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 six locations 6a for positioning the diodes 6. Such a module 1 is intended to be fixed, for example, inside a projector of vehicle.
    [0011] With reference to FIG. 2, the optical element 7 made of transparent material according to the invention is solid and is made for example of PC (polycarbonate), and plays the role of an optical lens. This optical element schematically comprises two lateral lugs 11, 12 and a central body 13 located 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 abut against a flat surface, by means of its lugs 11, 12.
    [0012] Advantageously, the body 13 of this optical element 7 is divided into five elementary portions 16, 17, 18, 19, 20 full, each characterized respectively by an inlet surface 21, 22, 23, 24, 25 and by an outlet surface 26, 27, 28, 29, 30. This optical element 7 thus has two end elementary portions 16, 17, forming the two arms 14, 15 end, and three intermediate elementary portions 18 , 19, 20 positioned between the end portions 16, 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 each other, and are substantially aligned with the two legs 11, 12. Each portion 16, 17, 18, 19, 20 is elongated, the 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, 25 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 aligned alternately with the five elementary portions 16, 17, 18, 19, 20, each cavity thus being delimited by a wall of a portion elementary and by a wall of an adjacent elementary portion. The two inlet surfaces 21, 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 which 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 horizontal point or segment in the vicinity of the entrance surface such that a majority of 15 rays from this point or points of the line emerge from the exit surface being parallel to the same plane. Referring to Figure 1, the radiator 2 and the substrate 3 is a monoblock element preferably of metal. The substrate 3 is comparable to a thin plate having an implantation face 43 provided with 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 six LEDs 6, 61, 62 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 six LEDs 6, 61, 62 are arranged along the edge delimiting the recess 44, three LEDs 6 being placed on the protrusion 45 and the other three LEDs 6, 61, 62 being placed 3036162 9 at the face 43 of the substrate 3 located at a lower altitude than that of the protuberance 45. In this way, three L ED 6, 61, 62 end frame three intermediate 6 LEDs, raised. Each LED 6, 61, 62 has a photoemissive element of substantially square shape and having a small thickness. The six LEDs 6, 61, 62 are rotated differently with respect to the direction towards the front, 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. The oblique edges extend opposite a transverse axis of the optical element. These edges can, in front view, make between them an angle of 45 °. These six LEDs 6, 61, 62 are arranged to emit a light beam in the same direction. As illustrated in FIG. 1, the optical element 7 according to the invention is fixed on the substrate 3 so that each of the six LEDs 6, 20, 61, 62, secured to the substrate 3, come to be respectively positioned at the an input surface 21, 22, 23, 24, 25 of the optical element 7, illustrated in FIG. 2, with the exception of the input face 21 which is opposite two LED 6, so that each LED can send a light beam to the input surface 21, 22, 23, 24, 25 with which it is associated, the beams passing through the input 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 coming from each input surface 21, 22, 23, 24, 25 may either directly reach the corresponding exit surface 26, 27, 28, 29, 30, or may be previously reflected on the walls 31. , 32, 33, 34, 35, 36, 37, 38 before arriving at the exit surface. The walls 31, 32, 33, 3036162, 34, 35, 36, 37, 38 prevent the light beams emitted by an LED placed at an elementary portion 16, 17, 18, 19, 20, from reaching a maximum of at the exit surface 26, 27, 28, 29, 30 of an adjacent elementary portion. The elementary portions 16, 17, 18, 19, 20 act separately and independently, in order to obtain a resulting light beam, without parasitic interference. FIGS. 3A to 7B illustrate an example of use of a light module 1 according to the invention, by decomposing the resulting light beam, into a plurality of components each derived from an elementary portion 16, 17, 18, 19, 20, module 1 associated with the corresponding LED. The elementary portion 16 comprises two light sources 61, 62: a first LED 61 produces at least a first beam, this first beam being a component of a code beam, a second LED 62 produces at least a second beam, this second beam being a component of a road beam. The light beam coming from the second LED of the elementary portion 16 is illustrated in FIGS. 11 to 13. A code beam generally comprises an oblique cut. Preferably, the first beam generates at least a portion of the oblique cutoff of the code beam, said portion of the cutoff being defined by a portion of the oblique cutoff of the cutoff of the code beam. In this way, with reference 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 lighting towards the left focusing on the scope. This lighting is rather concentrated and intense. Referring to FIGS. 4A and 4B, the left intermediate elementary portion, associated with the corresponding LED 6, can be used to produce horizontally extended illumination to the left. This lighting is rather low intensity and spread transversely to the vehicle.
    [0013] With reference to FIGS. 5A and 5B, the central intermediate elementary portion 19, associated with the corresponding LED 6, may be used to produce horizontally extended illumination as far as to the left. This lighting is rather low intensity and spread transversely relative 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 horizontally extended illumination to the right. This lighting is rather low intensity and spread transversely to the vehicle.
    [0014] Referring to Figs. 7A and 7B, the end elementary portion 16 located to the right of the module 1 is associated with two corresponding end LEDs 61 and 62 (illustrated in Fig. 1). Preferably, the first LED 61 produces a left-of-span illumination inclined at an angle of 45 ° with respect to a horizontal axis. This illumination is rather concentrated and intense and is illustrated in the isolux diagram of FIG. 7B. The illumination produced by the second LED 62 is illustrated in FIGS. 11 to 13. The lights produced by the portions 16, 17, 18, 19 and 20 are extended horizontally. They are dedicated to illuminate the road facing the driver. These can in particular be used to generate a portion of the lighting required by the dipped beam of a vehicle. The different lighting distributions illustrated in FIGS. 3B to 7B show that these components comprise a horizontal cut, ie there is no light beyond the line indicating the horizontal on the Isolux diagrams of the light beam. The second light source 62 of the portion 16 is capable of generating a high beam. The position of the second source is determined so that when the source is in this position, it generates a lighting corresponding to a high beam. The high beam does not have a cutoff. The intensity of high beam is concentrated and intense along the optical axis. They illuminate at least partially beyond the horizontal cut of the dipped beam.
    [0015] 3036162 12 The intensity required by the regulations can be of the order of 40500 candela. The low beam light provides good visibility without dazzling other road users and generally includes a horizontal cut and an oblique cut to illuminate the roadside signs and sidewalks. or the aisles. The intensity of the low beam is of the order of 36000 candela. Figure 8 illustrates the displacement vector between the positions of the two sources. The two sources are indicated by references 61 and 62. The displacement vector comprises a vertical component along the z axis (-10 ÔZ) and a lateral component along the y (Ôy) axis, the y and z axes being illustrated on FIG. the figure. The intersection 52 between the vertical axis 50 and the horizontal axis 51 is the trace of the optical axis of the portion 16. The vertical term is understood when the lighting module is disposed under normal conditions of use. . Figure 9 schematically illustrates the difference in the arrangement of the images between those produced by the first source and those produced by the second optical source respectively. Preferably, the center 63 of the first LED 61 is slightly above the optical axis. The edge of the LED is inclined at 45 ° and intersects the optical axis. Indeed, it is the edge of the LED that produces the cutoff. The images produced by the first source are illustrated in FIG. 9. The images are all located below the cut-off 910. Preferably, the images are aligned and / or superimposed to form said oblique portion of the cut-off of the first beam. It is required by law that high beams emit forward for a minimum distance of 100 meters. The lighting produced by high beams must therefore be concentrated and intense along the optical axis. In order to trace the images produced by the first LED 61, the displacement vector must comprise a downward vertical component, -Z, such that the second position is located under the optical axis, as illustrated in FIG. The second light source 62 is offset vertically with respect to the focal point by a distance such that a plurality of images of the second source 62, formed by the projection of the second light rays by the optical element, are disposed at the least partially above the cut of the first beam. The second beam has a complementary light beam type 5 light distribution. Figure 9 illustrates the displacement of the images. The images that were under the beam cutoff code for the first source are moved over the cutoff and contribute to the volume 920 (width and thickness) of the road beam. On the other hand, the second LED 62 is also shifted laterally relative to the first position so that the oblique images forming the 15 degree cutoff for the first LED 61 are superimposed on the horizontal and vertical images derived from the vertical axis z. This offset γy is illustrated in FIG. 8. The second LED 62 is shifted transversely to the focal point by a distance such as a plurality of images of the second LED 62, formed by the projection of the second light rays by the optical element, are concentrated at the optical axis. The image overlap contributes to the concentration of the road beam along the optical axis of the portion 16. This concentration of the beam is illustrated by the central ellipse 915 of FIG. 9. These two positions of the LEDs 61 and 62 on the Figure 8 are located in the vicinity of the focus of the outer surface 26, which is located on the optical axis. The center of the first source (61) is substantially shifted up and to the left of the focus and the center of the second source (62) is substantially shifted downward and to the right of the focus. The fact that the two sources are close to each other ensures that the optical module is compact and that there is continuity in the illumination generated by the two beams. The left and right are defined with respect to the optical axis, which is oriented in the direction of propagation of light. Various embodiments are described for coupling the two types of lights in a single optical module or in an optical module portion.
    [0016] In a preferred embodiment, the optical portion 16 of the optical element 7 has an optical source in each of the two positions. Therefore, in order to produce a passing beam, the first light source 61 is turned on and the second light source 62 is turned off. In order to exclusively produce a road-type beam, the first light source is turned off and the second light source is turned on. It is also possible to combine the two beam types by lighting both sources to produce a more intense beam-type beam.
    [0017] Advantageously, the distance between the two LEDs depends on the dimensions of the lens and its optical characteristics. However, the smaller the lens size, the more precise the positions of the light sources. Preferably, the dimensions of the optical element 7 are of the order of 20 mm in the direction of the height and of the order of 110 mm in the direction of the width. For an optical element having a size of this order of magnitude, the distance between the two optical sources intended to generate the beams of the road and crossing type in an identical optical portion is preferably between 2 and 5 mm, preferably between 3 and 4 mm.
    [0018] This distance is advantageously less than a fraction of the focal length of the optical portion. This fraction is preferably of the order of rtan (0.570), ie f / 100 if f is the focal length of the optical portion. This distance is more easily achievable by means of an addressable diode matrix comprising at least two light emitting surfaces. The diode arrays 25 have the advantage of having close light emitting surfaces that can be turned on separately. On the other hand, the emitting surfaces are smaller than for independent LEDs. There is also interest in having the light emitting surfaces adjacent so that the maximum intensity of the driving beam is not located too high. As a result, when the two sources are adjacent, the illumination generated by the two sources is distributed uniformly.
    [0019] FIG. 10 illustrates the entry surface 21 of the elementary portion 16. It comprises the two LEDs 61, 62 intended to generate a lighting comprising the oblique cut of a dipped beam and a high beam respectively. Only the emitting surfaces of the LEDs have been shown, and not their connecting surfaces. Each of the positions of these LEDs is defined above and below the optical axis of the elementary portion 16. It is the position of the source relative to the optical axis that determines the ray propagation direction. The first LED produces lighting whose intensity is below a horizontal and oblique cut. The second 10 LED produces a high beam whose beam is raised and more concentrated with respect to the beam of the dipped beam. In Fig. 10, the two light emitting surfaces are adjacent, as in an addressable diode array. FIG. 11 is an isolux diagram of portion 16 of optical element 7. Only the LED dedicated to the dipped beam is lit. The horizontal cut and the oblique cut at 15 degrees, which are characteristics of the dipped beam, are visible. FIG. 12 illustrates an isolux diagram similar to that of FIG. 10, however only the LED 62 dedicated to the high beam is on.
    [0020] As discussed in the scheme of Fig. 9, the illumination distribution is shifted upward, and the light intensity is concentrated in a vicinity of the center of the diagram corresponding to the optical axis. FIG. 13 illustrates a third isolux diagram relating to the optical element 7 in which the LEDs dedicated to the dipped beam and to the main beam are lit. This results in a distribution of lighting above and below the horizontal cutoff with a concentration of light intensity in the vicinity of the center of the diagram. As is clearly shown in FIGS. 3A, 4A, 5A, 6A, 7A, the light beams produced by each LED 6, 61, 62 of the light module 1, 30 pass through only the elementary portion 16, 17, 18, 19, 20 to which the LED or LEDs are associated, without being able to go to 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 the invention, is capable of producing a resulting light beam, which is sharp and accurate, because devoid of any 5 parasitic light beams due to light interferences between the different elementary portions 16, 17, 18, 19, 20 of the module 1. Although the LEDs 6, 61 and 62 are illustrated identically in the figures, they can naturally have different structural, geometrical and luminous characteristics within the same light module 1, the LEDs being chosen in FIG. according to the specific needs of lighting era. Preferably, the optical source is a light emitting diode and the above description has been made in this context. Such a diode provides good light beam quality while remaining small in 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. 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 capable of generating a beam having properties similar to the properties described above. The manufacturer of the projector has only to design a single optical element, with unique manufacturing tools (molds for example), making it possible to manufacture a single optical module compatible with the different types of beam fires, in a preferential manner, the fires of crossing and the driving light. The optical module according to the invention has a compact geometry, and is therefore compact.
    [0021] 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 of road lighting, signaling, or lighting of the passenger compartment. . In this way, it is not necessary to put another optical deflection element or cache. In other words, the light device may be devoid of a lens, reflector or cover after the exit surface.
