Definitions

  • the invention relates to a lighting module, in particular for a motor vehicle, the lighting module comprising a first lighting function of the dipped type with an essentially horizontal cut-off of the beam. More particularly, the invention relates to a lighting module comprising a second high-beam type lighting function ensured by an additional beam supplementing the high-beam.
  • a lighting module comprising two reflectors of the ellipsoidal type is known from the patent document US 4,914,747 . These two reflectors correspond to half-ellipsoids and are superposed with their reflective surfaces oriented towards each other, ie oppositely.
  • the module comprises a specific light source for the upper reflector and a common light source for the two reflectors, the specific light source being located at the level of the focus of the upper reflector to participate in the formation of a dipped type lighting beam and the common light source being located at the focus of the lower reflector to participate in the formation of a road-type lighting beam.
  • a horizontal mask with a cutting edge is provided close to the second focal points of the two reflectors.
  • a lens is arranged after the cover with its optical axis coinciding with the optical axis of the module.
  • the lens is arranged so that its first focal point is close to the second focal points of the reflectors.
  • the code beam the light rays emitted by the specific light source of the upper reflector are reflected by the internal surface of the reflector approximately towards the second focal point of the reflector. Part of the rays pass in front of the cut edge of the cover. These rays encounter the lens in its lower half and are then refracted upwards.
  • the mask conceals part of the rays which would otherwise encounter the lens in its lower half and would constitute the upper part of the beam emitted after passing through the lens.
  • the dipped beam thus has an upper limit called cutoff.
  • the light rays emitted by the common light source are reflected by the upper reflector towards the bottom of the upper half of the lens and also by the lower reflector towards the second focal point of the reflector.
  • part of the rays pass in front of the cover and meet the upper half of the lens.
  • Another part of the rays is reflected by the mask or reflected by a reflecting part of the latter, to then be refracted by the lower part of the lens in order to form the upper part of the beam, which has a low cut-off.
  • the position of the shield is therefore decisive for cutting off the upper part of the beam, which is added to the lower part of the beam coming from the lower reflector.
  • This superposition makes it possible to obtain a beam with a view to ensuring the route function.
  • This module has a zone of weaker lighting at the level of the cut in the road type beam and corresponds to a particular embodiment of US 4,914,747 .
  • the lower part of the beam is particular because it comes from an unfocused source.
  • US 2009/0097268 A1 also shows a lighting module comprising two concave reflectors, a cover and an optical element.
  • the object of the present invention is to obtain a compact device making it possible to participate in the generation of two beams.
  • the object of the present invention is a lighting module, in particular for a motor vehicle, according to claim 1.
  • a lighting module in particular for a motor vehicle, according to claim 1.
  • Optional additional characteristics of this lighting module are presented in dependent claims 2 to 10.
  • This lighting module can be comprised in a lighting device in particular for a motor vehicle as described in the dependent claims 11 and 12.
  • a compact module is thus obtained which makes it possible to emit two complementary beams. Indeed, by positioning a first light source at a first focus of the first reflector, the first light source illuminating only in the direction of the first reflector, and by positioning a second light source at the first focus of the second reflector, the second light source illuminating only in the direction of the second reflector, the beam generated by the first reflector will have a shape cut-off approximately complementary to that of the beam generated by the second reflector. A complete beam without relatively homogeneous cut-off is thus obtained, when the two sources are switched on, and a clean cut-off beam, when only one of the sources is switched on.
  • the cutoff is sharp because the cutoff edge is focused, since it is positioned at the focal point of the corresponding reflector.
  • a first light source is positioned at the first focus of one of the reflection surfaces of the first reflector
  • a second light source is positioned at the first focus of the other reflection surface of the first reflector.
  • the optical axes of the first and of the second reflectors are in particular oriented globally in the same direction. That is to say that when the optical axis of the first reflector is oriented towards the front of the vehicle, the optical axis of the second reflector is also oriented towards the front of the vehicle.
  • the first reflector when it is mounted in a vehicle, it can generate a beam of the dipped beam type or participating in a dipped beam, when the first source is on.
  • the second light source is switched on and the beam generated by the second reflector then complements that of the first reflector, to form a high beam.
  • the curved profile of the cut-off edge of the second module of the lighting device described by claim 11 is globally centered on the optical axis of the module.
  • This module allows when the curvature is convex upwards, the first reflector being oriented upwards, to obtain a beam with a horizontal upper cut-off, with the exception of a curved depression, or rounded, oriented downwards.
  • the curved profile is present on the two reflecting and opposite surfaces of the bending machine.
  • the curved profile is limited to a central part of the cover, the rest being essentially flat.
  • the first face of the cover and the second face of the cover meet in a cut-off edge.
  • the second focal points of the first and of the second reflector are merged into a second common focal point, the cutting edge being positioned at the level of the second common focal point.
  • the cut made by such a module has the particularity that it thus compensates for the loss or inhomogeneity resulting from the non-zero thickness of the mask and the rounding of its cut-off edge. Indeed, the cutting of the beam of the first reflector is thus practically coincident with the cutting of the second reflector beam. It is for example possible to obtain a homogeneous main beam.
  • At least one of the first and second faces of the mask are reflective.
  • a better recovery of the luminous flux is thus obtained.
  • the rays meeting the reflective surface of the shield will be sent forwards and participate in the formation of the beam.
  • caches with a reflective surface will be referred to as a folder.
  • the cover is a thin element whose complex profile decreases from the cut edge towards the rear of the module so as to form a complex surface.
  • the complex surface corresponds to a centered thin band of the folder.
  • the cut edge has an essentially straight profile when projected into the general plane of the folder.
  • the first light source comprises a light-emitting diode, or LED, emitting in an overall direction oriented towards the first reflector
  • the second light source comprises an LED emitting in an overall direction oriented towards the second reflector.
  • LEDs comprise a substrate supporting a semiconductor element, which generates light when supplied with electric current. LEDs generally emit a cone of light oriented on one side of the half-plane containing the substrate, side being that where the semiconductor element is located. The axis of this cone corresponds to the global emission direction of the LED.
  • the light sources are carried by the cover, the first light source on the first face of the cover and the second on the second face of the cover.
  • the invention also relates to a lighting device, in particular for a motor vehicle, according to claim 11.
  • This device makes it possible to minimize the errors in the central part of the beam projected in road mode.
  • the superposition of the beams coming from the different modules allows a certain freedom in terms of adjustment precision in a horizontal plane due to the covering of the projecting central part of the beam of the first module by the central part curved downwards from the harness of the second module.
  • the first lighting module comprises a second lighting function of the road type where an additional beam complements the beam of the first function.
  • the second lighting module comprises a cutting edge of constant thickness so that the second reflector of the second module makes it possible to generate a third beam having a lower cutoff with a curvature complementary to the curvature of the upper cutoff of the second beam.
  • the invention also relates to a lighting device, in particular for a motor vehicle, comprising: a first lighting module comprising a first low-beam type lighting function with an essentially horizontal cut-off of the emitted beam, the cut-off having a projection at its central part ; a second lighting module separate from the first and ensuring a lighting function intended to supplement the beam of the first module ensuring a road-type lighting function, the lighting function of the second module comprising a low cut-off such that it covers the beam of the first module at least in its central part.
  • the low cut-off of the beam of the second module can be ensured by a cover of suitable profile positioned close to the focus of convergence of the rays coming from the module.
  • the profile of the cut is advantageously essentially horizontal with a central part slightly curved downwards so as to cover the projection of the cut of the first module.
  • each reflection face of the first reflector is included in a portion of an ellipsoid, the two portions of ellipsoids being secant along a line of separation separating the two reflection faces.
  • the shape of this portion may not be strictly that of an ellipsoid and may be approximately ellipsoid.
  • the two reflection faces join at said separation line.
  • the optical axes of the two reflection faces form between them an angle of between 20 and 40 degrees, preferably between 25 and 37 degrees, in particular 31 or 35 degrees. These values make it possible to improve the quantity of light focused by the reflectors.
  • each light-emitting diode comprises a reference axis.
  • the reference axes of the light-emitting diodes form between them an angle of between 20 and 30 degrees. This range of values allows more freedom in the positioning of the LEDs. This advantageously allows these reference axes of the light-emitting diodes to make between them an angle different from the angle which the optical axes of the reflection faces of the first reflector make between them.
  • this angle between the reference axes of the LEDs can be 26 degrees while that between the optical axes of the reflection faces of the first reflector is 31 or 35 degrees.
  • the reference axes can correspond for these LEDs to the passing axis by the corresponding LED and perpendicular to one of the long sides of the emitting surface of the LED, this emitting surface being rectangular.
  • the light-emitting surfaces of the light-emitting diodes are substantially in a plane passing through the optical axis of the lighting unit.
  • Their center is preferably in the plane passing through the optical axis of the lighting unit, generally corresponding to the optical axis of the lens.
  • the second reflector of the module comprises a light-emitting diode, located at the first focal point of the second reflector and located below the optical axis, in particular at 11 mm below the optical axis.
  • the reflective properties of the reflective surfaces are conferred by a coating of reflective material deposited on a part conferring the desired shape on the reflector. For example, by aluminating a reflector of generally elliptical shape.
  • the figure 1 is a schematic perspective view of a motor vehicle headlamp lighting module.
  • the lighting module 1 comprises a first upper half-plane reflector 2 consisting of a double concave reflecting surface.
  • Each of these surfaces 2a and 2b is a surface of revolution of an ellipse section around an axis of symmetry. These two surfaces intersect in the vertical median plane of module 1, thus forming an upper reflector in the form of a double bulb.
  • the two axes of revolution or symmetry 30 and 31 of the surfaces, respectively 2b and 2a, of the reflector intersect so that the beams reflected by these surfaces converge.
  • a light source 5, 6 of the light-emitting diode or even LED type is located approximately at the first focus of each surface 2b, 2a forming the upper reflector 2.
  • the first focus of each surface is located on the axis of revolution.
  • the second foci of the surfaces are also located on the respective axes of revolution.
  • the surfaces 2a and 2b are oriented so that these second focal points correspond to the point of intersection 13 of the two axes.
  • the module 1 also comprises a lower reflector 3 also half-plane consisting of a concave reflective surface described, as for each of the double surfaces of the upper reflector, by an ellipse section in rotation around an axis of rotation 32 or symmetry.
  • a light source 7 also of the LED type is positioned at the level of the first focal point of the lower reflector.
  • the reflector is dimensioned and arranged with respect to the upper reflector so that its second focus corresponds to the second focus of the upper reflector.
  • the main optical axis 4 of module 1 passes through the plane which contains the axes of symmetry 30, 31 of the reflection surfaces 2b and 2a of the first reflector 2.
  • the reflective internal surfaces of the reflectors may not be perfectly elliptical and have one or more specific or complex profiles with a view to optimizing the light distribution in the lighting beam. This may imply that the surfaces 2a and 2b of the first reflector 2 or the surface of the second reflector 3 are not perfectly symmetrical in revolution.
  • An essentially planar interface is provided between the first reflector 2 and the second reflector 3, in order to ensure the connection between them and also in order to support the light sources 5, 6 and 7. These light sources are provided to emit in a half- plane, sources 5 and 6 in an upper half-plane and source 7 in a lower half-plane.
  • This type of light source has the particularity of being particularly compact to the point of being able to be likened approximately to a point source.
  • Other known types of light source can however also be considered.
  • the light rays emanating from the light sources roughly assimilated to point sources are reflected by the reflective surfaces of the reflectors 2 and 3 and all converge towards the second common focus 13 of the reflectors.
  • the light sources are not point-like and the shape of the reflecting surfaces are not necessarily perfectly elliptical so that the reflected rays do not all converge towards the second focus 13 but rather towards an area close to the second focus 13.
  • a reflective optical element 8 commonly called a “folder” is arranged on the optical axis 4 and with its front edge called the "cut-off edge” 9 close to the second focal point 13.
  • This thin and essentially planar folder 8 comprises a surface upper reflecting surface and a lower reflecting surface. In this way, the light rays emanating from the reflectors 2 and 3 converging towards the second focal point 13 and which encounter a surface of the bender 8 are reflected.
  • a lens 20 is provided on the optical path of the device.
  • This lens of the convex plane type has its focal point corresponding to the second focal point 13 of the reflectors and its optical axis coinciding with the optical axis 4 of the module so that the light rays coming from the focal point 13 are transmitted essentially parallel to the optical axis 4.
  • Other types of convergent lens can be envisaged, such as for example a biconvex lens or else of the convergent meniscus type.
  • a reflector of the paraboloidal mirror type is also possible. In this case, its optical axis would be essentially perpendicular or at the very least secant to the axis 4 and its focal point would coincide approximately with the focal point 13. Such a reflector would then reflect the light rays in a direction essentially parallel to its optical axis, that is to say perpendicular to the optical axis 4 or along an axis secant therewith.
  • the picture 2 is another schematic view of the module from the figure 1 from a different angle.
  • This view illustrates the inclination of the upper reflector 2 with respect to the lower reflector 3.
  • the axes of revolution of the surfaces 2a and 2b of the upper reflector, as well as the general optical axis 4 of the module are coplanar.
  • the axis of revolution of the lower reflector 3 forms an angle ⁇ with the axis with the general optical axis 4 of the module 1.
  • This angle is quite small, typically a few degrees and is essentially due to the fact that the folder ideally infinitely thin actually has a certain thickness.
  • the folder actually has a triangular section in a longitudinal and vertical median plane.
  • the folding machine is best represented at the picture 3 which is an enlarged perspective view of the cut edge thereof.
  • the folder 8 has a finite and increasing thickness from the cutting edge 9 towards the rear thereof.
  • the cutting edge 9 has a projection 12 approximately at its central part, that is to say the part positioned at the level of the optical axis 4.
  • the upper surface and the lower surface on either side of this projection 12 are essentially planar.
  • the jump thus constitutes a discontinuity in the profile of the cut-off edge.
  • the cut edge 11 on the right side when looking from the reflectors to the lens, i.e. the left side in the representation at the picture 3 is slightly raised relative to the opposite side 11'.
  • the cut made by the bender will therefore obscure more rays coming from the right parts of the reflectors, that is to say the rays which will then form the left part of the beam projected by the lens 20. This left part will thus have a cut more lower than the right part of the beam, the jump creating an oblique portion. This makes it possible to obtain a code type break as shown in figure 5 .
  • the figure 4 is a schematic plan and sectional view along a median plane of the module of the figures 1 and 2 .
  • the purpose of this figure is to illustrate the role of the folder and the cut it operates.
  • One of the upper light sources 5 or 6 is shown there as well as the profile of the corresponding reflecting surface. It is therefore on this part of a section along a longitudinal median plane of one of the reflecting surfaces 2a, 2b, forming the upper reflector 2.
  • the lower light source 7 is also represented there as well as the profile of the reflecting surface corresponding to the lower reflector 3.
  • the folding machine 8 with a wedge-shaped section is also represented there.
  • the light ray 15 emitted from the first focus of the first reflector by the upper light source 5 or 6 is reflected by the reflecting surface of the upper reflector towards the second focus 13. Since the light source is not point-like, it also emits light rays slightly offset (represented in dotted lines) which after reflection by the reflecting surface will not converge exactly towards the second focal point 13. Thus, certain rays will pass through the focal point and will be refracted by the lens 20 parallel to the global optical axis 4. These rays will correspond to the upper cutoff of the lower beam 17 emitted by the module 1 and shown in figure 5 . Other rays pass in front of the cutting edge 9 and go towards the lower half of the lens. As they pass over focus 13, lens 20 will refract them downward.

  • This imprint does indeed include a generally horizontal cut with, however, a jump or step generated by the jump 12 of the cutting edge 11 of the bender 8. This cut-off profile is required by law in order to limit the dazzling of drivers coming against it. meaning.
  • the lower light source 7 and the lower reflector 3 operate in reverse with respect to the combination of the upper reflector 2 and the sources 5 and 6.
  • a light ray 14 emitted from the first focus of the lower reflector 3 by the lower light source 7 is reflected by the reflecting surface of the lower reflector 3 towards the second focal point 13.
  • Certain rays will pass through the focal point 13 and will be refracted by the lens 20 parallel to the global optical axis 4. These rays will correspond to the lower cut-off of the upper beam 16 emitted by module 1, shown in figure 5 .
  • Other rays pass, for some in front of the cutting edge 9 to reach the upper part of the lens 20, and for others, meet the lower reflective surface of the bender 8 and are reflected towards the lower half of the lens. These rays therefore pass below focus 13 and lens 20 will refract them upwards; they correspond to the part of the upper bundle 16 located above the lower cutoff.
  • the lower light source 7 performs the road-type lighting function in combination with the upper light sources 5 and 6.
  • the cut-off edges 9 have a constant thickness.
  • the footprint 16 of the upper beam and the footprint 17 of the lower beam are complementary.
  • a road type beam is obtained. Due to the non-zero thickness of the folder at the level of the cut-off edge, a zone of weaker illumination is present at the border between the two cut-off profiles. This is not a black area but rather a lower light area.
  • FIG. 6 and 7 Another lighting module 100 similar to that of the figures 1 and 2 is illustrated in figures 6 and 7 . It is very similar to module 1 but differs essentially in that it comprises a single upper light source 105, in that the bender 108 comprises a complex surface, and in that the upper reflector 102 comprises a single reflective surface axis of rotation coinciding with the general optical axis 104 of the module 100.
  • the presence of a single light source associated with the upper reflector means that the lighting of this module is weaker than that of the module 1 of the figures 1 and 2 . It is designed to be used in combination with module 1 to provide additional lighting.
  • a lower light source 107 is associated with the lower reflector 103.
  • the 108 Folder is best illustrated at figure 8 . It is slightly domed upwards at the cut edge. It has a complex surface on both upper and lower sides. Viewed from the front from the lens 120, the folder has an upwardly domed profile, approximately centered on the optical axis and symmetrical at the cut edge. The cut edge is located at focus 113, which corresponds to the second focus of upper reflector 102 and lower reflector 103. This curved profile decreases from cut edge 109 towards the rear of the folder. The rear part of the folder is thus essentially flat.
