  • the figure 2 illustrates a first principle of forming a virtual image of a light source by means of a planar reflector, this first principle forming the basis of a first embodiment of the invention.
  • the light source S illuminates essentially in a half-space directed towards the upper part of the figure, more particularly in a solid angle oriented upwards.
  • a first generally planar reflecting surface 104 is inclined with respect to the main direction of the solid illumination angle of the light source S. The rays of the light source S are thus reflected by the first reflective surface 104 to a second reflective surface 106 disposed laterally or outwardly of the first reflective surface.
  • the second reflective surface is of parabolic profile with a focus F positioned at the rear of the first reflecting surface 104, more particularly where the first reflecting surface 104 forms a virtual image S 'of the light source S.
  • the rays emitted by the light source and meeting the first plane luminous surface 104 are reflected according to the general principle of Snell-Descartes reflection with a reflection angle equal to the angle of incidence, the angles of reflection and incidence being measured in relation to the normal to the reflection surface passing through the point of incidence.
  • FIG. 2 Three rays are illustrated at figure 2 to illustrate the formation of a virtual image S 'of the light source S.
  • every ray of light passing through the focus of a parabola and meeting it is reflected in a direction parallel to the axis of the parabola.
  • the extension of the ray reflected towards the rear of the reflector 104 shown in dashed lines converges towards the point S 'of the virtual image of the light source.
  • the angle 90 ° - ⁇ that forms the extension of the ray reflected with the reflective surface is identical to the angle 90 ° - ⁇ that forms the incident ray with the same surface.
  • the same is true for the second ray 110 which encounters the first reflecting surface 104 at a point of incidence B and then the second reflecting surface 106 at a first point of incidence B ', as well as for the third ray 112 which encounters the first reflecting surface at a first point of incidence C and the second reflecting surface at a second point of incidence C '.
  • the virtual image S 'thus corresponds to the symmetry of the light source with respect to the plane of the reflecting surface, in the manner of a plane of symmetry. This arrangement makes it possible to offset a light beam laterally in a compact and optimized manner. Indeed, the virtual image is formed at the rear of the first reflective surface, which allows to size the second reflective surface larger than if the focus of this surface was to be disposed between the first and second reflective surfaces.
  • the Figures 3 and 4 illustrate a first embodiment of a lighting and / or signaling module according to the invention and applying the principle illustrated in FIG. figure 2 .
  • the figure 3 is seen in elevation of the module and the figure 4 is a sectional view along the axis 4-4 of the figure 3 .
  • the module 102 essentially comprises a first reflector 116 with five planar primary reflective surfaces distributed around the main axis 114 of the module. It also comprises five electroluminescence diode-type light sources S, the diodes being arranged facing the flat primary reflective surfaces 104 of the first reflector 116.
  • the light sources S illuminate in a half-space oriented along the main illumination direction 126.
  • the module also comprises a second reflector 118 disposed laterally or externally to the first reflector, comprising five parabolic secondary reflecting surfaces 106 respectively facing the flat primary reflective surfaces 104 of the first reflector 116.
  • the secondary parabolic reflective surfaces 106 of the second reflector are preferably surfaces of revolution about an axis passing through the pair S-S ', namely the light source and its virtual image. Indeed, with reference to explanations of the phenomenon explained above in relation to the figure 2 , the rays emitted by the light source S and meeting the reflecting surface 104 will be reflected to the secondary reflecting surface 106 while forming a virtual image S 'of the light source S. In other words, the secondary reflecting surface 106 sees the incident rays reflected by the primary reflecting surface as if they originated directly from the virtual image S 'located behind the reflecting surface.
  • the module 102 may also comprise a Fresnel lens 120 as well as a transparent cover 122.
  • the second reflector 118 and the Fresnel lens constitute an optical system capable of harvesting the light rays reflected by the first reflector 116 and forming a light beam in a direction 128 generally parallel to the main axis 114 of the module 102.
  • the module 102 may also comprise a third reflector 124 disposed generally transversely, preferably perpendicular to the main axis 114 of the module 102.
  • This third reflector 124 extends from the first reflector 116 to the second reflector so as to reflect the rays. which would otherwise be lost, that is to say the rays coming directly from the light source S or coming directly from the first reflector and not reaching the second reflector 118.
  • the first reflector 116 comprises, in addition to the flat primary reflective surfaces 104 inclined relative to the third reflector 124, flat surface portions 104a generally perpendicular to said third reflector 124. These surface portions are substantially smaller in size than the surfaces. 104.
  • the surface portions 104a are intended to reflect the rays coming directly from the light source and which otherwise would not reach the second reflector 118. Indeed, the rays emitted laterally by the light source S, such as a ray generally horizontal and oriented towards the main axis 114 would, in the absence of this surface portion 104a, reflected by the first reflector towards the third reflector. Depending on the dimensioning of the module, the reflected ray could again meet the first reflector at a point of incidence located higher. These multiple reflections are the seat of losses and confer, moreover, a great uncertainty as to the trajectory of the ray.
  • the module may comprise a single light source centered on the main axis of the module. If the planar primary reflecting surfaces 104 are arranged so that the virtual image of the light source is also located on the main axis, the reflecting surface 106 of the second reflector 118 can be of revolution without inflection with respect to several portions. In fact, if the light source S and its virtual image S 'are aligned with the main axis 114, the reflecting surface 106 of the second reflector 118 can then be formed by the rotation of a parabolic profile around said axis.
  • the figure 5 illustrates a second principle of forming a virtual image of a light source by means of a hyperbolic reflector, this second principle forming the basis of a second and third embodiment of the invention.

  • the light source is disposed at the focus F 2 of the hyperbola with respect to which the curve is convex.
  • the hyperbolic reflecting surface by reflecting the rays emitted by the light source, forms a virtual image S 'of the light source S at the location of the focus F 1 .
  • a first ray 208 emitted by the light source S is illustrated in FIG. figure 5 . It meets the reflective surface 204 at a first point of incidence A at an angle of incidence 5 with respect to the normal N to the tangent T at the hyperbolic profile at point A. It follows from the general principle of reflection of Snell-Descartes that the incident ray at point A will be reflected at an angle of reflection s with respect to the normal N, which is equal to the angle of incidence ⁇ . The reflected ray then meets the second reflective surface 206 at a second point of incidence A 'to be reflected along the optical axis of the dish.
  • the extension of the ray 208 reflected by the first reflective surface towards the rear of the reflecting surface is illustrated in dotted lines. It meets the focus F 1 of hyperbole. Indeed, if we consider the triangle formed by the foci F 1 and F 2 and the point of incidence A, the tangent T to the hyperbola is the bisector of the angle F 1 AF 2 . This characteristic is intrinsic to the definition of a hyperbola, as has been explained previously. It follows from this characteristic that the angles ⁇ and ⁇ are equal.
  • a second and a third radius 210 and 212 are illustrated: the ray 210 meets the hyperbola at a first point of incidence B, is reflected towards the parabola that it encounters at a second point of incidence B 'and is reflected according to a direction generally parallel to the corresponding radius 208 along the optical axis of the parable. The same is true for the third ray 212 which encounters the reflective surfaces at respective incidence points C and C '.
