  • the lighting module is of the cut-off type with preferably one or more light sources of the electroluminescence diode type.
  • the invention also relates to a lighting device comprising such a module.
  • the lighting module produces a cut-off lighting beam, namely that the beam has a limit or directional cut, preferably in a generally horizontal direction, above which the light intensity becomes very low.
  • This peculiarity of cut-off of the beam is found in particular in the lighting functions of low beam (or "code") as well as fog lights, in accordance with the legislation in force.

  • Such rays, if they were not reflected by the folder 8 would be reflected by the parabolic reflector 14 in a direction deviating slightly upwards relative to its optical axis.
  • the folder 8 thus ensures the cutting of the beam emitted by the module.
  • a radius as described above is illustrated in dashed lines at the figure 1 .
  • the folder 8 sends it to another part of the reflective surface of the second reflector 14 and is reflected in a direction deviating downwardly with respect to its optical axis.

This reflecting surface is a surface of revolution of an elliptical segment about an axis 110 in a half-space delimited by a plane passing through said axis 110.

  • the light source is preferably of the electroluminescence diode type particularly suitable for providing illumination in a half-space from a quasi-point source. .
  • the reflector 104 need not extend to the plane passing through the optical axis 110. Indeed, it may correspond to a surface of revolution on a sector of less than 180 °. It should also be noted that the reflective surface of the reflector 104 need not be perfectly a surface of revolution. In general, the reflector forms approximately a half-shell, the inner surface of which is generally of elliptical cross-section with a first focus and a second focus.
  • the module 102 also comprises a cover 108, which, in this example, is in the form of a generally flat reflective surface disposed in the plane comprising the optical axis 110 and delimiting the first reflector 104.
  • This reflecting surface is disposed near the second focus 112 of the first reflector 104, between the second focus and the first focus. It has a front edge 109, that is to say an edge directed in the direction of projection of the module 102, generally perpendicular to the optical axis 110 and passing through the second focus 112.
  • the module 102 also comprises a second reflector 114 of the parabolic type with a focus coinciding with the second focus 112 of the first reflector.
  • the reflector 114 comprises a concave reflective surface of parabolic section.
  • the parable has many flat geometric definitions.
  • the definition of a parable by focus and direction is an equidistance curve between a point (focus F) and a straight line (director D).
  • the tangent at every point of a parabola is bisector of the angle formed by the straight line passing through the focus and this point, and the line passing through this point and perpendicular to the directrix.
  • any luminous ray parallel to the axis of the parabola (that is to say, perpendicular to the directrix) is thus reflected by the parabola along a straight line passing through the focus. and vice versa.
  • the rays passing through the focus 112 of the reflector 114 will therefore be reflected in a parallel direction at its optical axis.
  • the optical axis of the second reflector 114 coincides with the optical axis 110 of the first reflector 104. It should be noted that the optical axis of the second reflector 114 may form an angle with the optical axis of the first reflector 104.
  • the angle between the optical axes of the first and second reflectors is preferably less than 90 ° in order to be able to harvest most of the rays reflected by the third reflector 118.
  • the reflecting surface of the second reflector 114 is oriented along its optical axis in the same direction as the reflecting surface of the first reflector 104.
  • the second reflector 114 is preferably supported by the first reflector 104. It could however be supported independently. Its reflective surface bypasses the first reflector 104 or, at the very least, is such that it does not obstruct the light rays reflected by the reflecting surface of the first reflector and coming out of the latter.
  • the module 102 includes a third reflector.
  • the latter is generally plane and passes through the second focus 112 of the first reflector 104 and intersects with the front edge 109 of the cover 108.
  • the third reflector 118 is inclined relative to the cover 108 so as to be able to send back to the light rays the second reflector 114.
  • the angle of inclination of the third reflector 118 with respect to the cover 108 is a function of various parameters such as, for example, the distance between the first and second foci of the first reflector and the height or extent of the reflecting surface of the second reflector 114. It generally varies between 0 ° and 90 °, preferably between 20 ° and 70 °, more preferably between 30 ° and 60 °.
  • the light rays emitted by the light source are thus reflected by the first reflector essentially towards the second focus 112. These rays are then reflected by the third reflector 118 towards the second reflector 114 in a direction parallel to the optical axis of said reflector.
  • some will be reflected by the cache 108 and then by the third reflector 118 before meeting the second reflector. Others will meet the third reflector directly and will be reflected towards the second reflector.
  • figure 4 is a simplified sectional view of the module of the figure 2 . It illustrates three rays emitted by the light source.
  • a first ray 120 coming from the central point of the light source is reflected by the reflective surface of the first reflector 104 towards the second focus 112 and then reflected by the third reflector 118 and then by the second reflector 114 in a direction generally parallel to the optical axis of the module 110 corresponding to the lighting direction.
  • a second ray 124 emitted by a front zone of the light source and meeting the reflective surface of the first reflector at the same point M as the first ray 120 is illustrated in FIG. figure 4 .
  • a third ray 122 is emitted from a rear area of the light source and meeting the reflective surface of the first reflector at the same point M as the first and second spokes 120 and 124 are illustrated in FIG. figure 4 . Because of its angle of incidence greater than the reference radius 120, it will be reflected by the reflective surface of the first reflector 104 so as to pass in front of the second focus 112 and directly meet the reflective surface of the third reflector 118 to then be reflected to the second reflector 114. The ray 122 reflected by the third reflector will meet the reflecting surface of the second reflector 114 at a lower point than that of meeting the reference beam 120 with this surface.
  • the ray 122 meeting the reflective surface of the second reflector 114 comes virtually from a point of the optical axis 110 located in front of the focus 112 and is therefore reflected in a direction inclined downward with respect to the illumination direction of the beam 120 and the optical axis 110 of the module.
  • a large part of the rays emitted by the light source will be reflected by the reflecting surface of the first reflector 104 towards the second focus 112, like the reference radius 120 illustrated in FIG. figure 4 .
  • These rays will meet the reflective surface of the first reflector 104 at different points and will therefore have different angles of incidence on the reflective surface of the third reflector 118, which will have the effect that they will meet the reflective surface of the second reflector 114 also at different points but will all be reflected, imperfections near the various elements of the module, according to a common direction parallel to the optical axis of the reflector.
  • the upper portion of the beam of these rays reflected by the second reflector will constitute the upper limit or cutoff of the emitted beam.
  • the rest of the rays emitted by the light source namely those which are reflected by the reflective surface of the first reflector so as to pass in front of or behind the second focus 112, like the spokes 122 and 124 shown in FIG. figure 4 , will be reflected by the second reflector 114 with an inclination angle directed downwardly relative to the illumination direction so as to enrich the illumination beam under the cut.
  • the cutoff is therefore formed by the intersection of the reflective surfaces of the cover 108 and the third reflector 118.
  • this intersection is a straight line.
  • This intersection may have a projection approximately towards its center so as to ensure a differentiated cutoff between the left half and the right half of the lighting beam, in accordance with the legislation for the lighting function of the code type or dipped beam headlamps.
  • the spokes passing behind the second focus 112 would be reflected by a lower part of the reflective surface of the third reflector (under the optical axis 110) so as to meet the second reflector 114 with an angle of incidence such that these rays would be reflected with a slightly upward inclination by compared to the reference lighting direction.
  • the ray 124 after reflection by the first reflector 104 in the absence of the mask 108, would be reflected by the third reflector 118 to the second reflector from a point of the optical axis 110 located behind the focus 112 and would therefore be reflected by the second reflector in a direction inclined upward relative to the reference direction.
  • the cover 108 therefore has the function of folding down the beam beams which, in the absence of this cover, would form an upper part of the beam.
  • This cover 108 is thus commonly called a “folder” and the front edge of the reflective surface of this cover is commonly called “cutting edge”.

  • the first reflector then comprises a more complex reflective surface with several first foci, the surface then being able to reflect the light rays of the different light sources arranged at the different first foci towards the second focus.
  • the first reflector in this case comprises several optical axes converging towards the second focus.
  • the light sources may for example, and not limited to, be arranged in a circular arc centered on the second focus and in a plane defining a half-space in which is the reflective surface of the first reflector.

  • the light source 130 is disposed approximately in the same plane 136 as the light source 106 of the first module 102. This arrangement makes it possible to predict the light sources of the two modules on the same support (not shown), which has a definite advantage as to the simplicity of assembly especially in view of the cooling constraints inherent to light sources of the electroluminescence diode type.
