Definitions

  • the present invention relates to lighting or signaling devices, intended in particular but not exclusively to motor vehicles.
  • Such devices include conventionally and schematically a light source emitting light rays which are collected by a reflecting mirror which reflects them towards a closing window and for protecting the lighting or signaling device to form a light beam lighting or signaling.
  • the light sources used may consist of incandescent lamps, halogen lamps or discharge lamps, these different lamps being able to coexist in a spotlight or a fire, each lamp being intended to fulfill a function, that is to say forming the light source at the origin of a beam having a photometry and a geometry predetermined regulations.
  • a global light beam comprising a regulatory cut-off, like a passing light beam or an anti-fog light beam
  • each elementary light beam that is to say generated by a single light source, includes such a cut
  • all elementary cuts exactly overlap to constitute the cut of the light beam global, which would otherwise be unclear, and therefore not in compliance with the regulations.
  • a device comprising several light sources constituted by light-emitting diodes connected in series and each located at the focus of a parabolic reflector.
  • Such a device can provide a signaling beam, but not a lighting beam.
  • WO-97/48 134 Also known from document WO-97/48 134 is a device comprising diodes light emitting devices mounted on a common support, the diodes emitting beams bright in complementary colors, for example amber and green-blue, so that the superimposition of these beams produces a resulting beam of white color.
  • An ice cream colored can be arranged to give a particular color to the beam emerging from the device, which again can provide a signaling beam, but not a beam lighting.
  • Document EP-A-0 158 330 also discloses a lighting device comprising several identical modules aligned, each module comprising a light source and a reflector. A common glass is placed in front of all the modules, so as to ensure the spatial distribution of the beam resulting from the superposition of the beams created by each module, so as to obtain for example a driving beam or a passing beam. The individual modules must then be positioned in relation to each other and by compared to ice with extreme precision to obtain for example a passing beam with clear cut.
  • the present invention is placed in this context and it aims to provide a device lighting or signaling using several light sources to form a light beam in accordance with predetermined regulations, the assembly of sources and their positioning in relation to the other elements of the lighting or signaling device helping to form this light beam being simple and reliable, the device lighting or signaling thus designed being inexpensive.
  • the present invention therefore relates to a lighting or signaling device, comprising at least two light sources, each light source being associated with a first optical system.
  • each first optical system forms a finite distance a real image of the light source, the images of the light sources being confused with a common place constituting a secondary source, and a second optical system having a optical axis passing through the secondary source forms a beam from this secondary source lighting or signaling.
  • Figure 1 a schematic sectional view of a first mode of realization of the present invention.
  • light sources 10A and 10B arranged on a frustoconical crown 12 of axis of revolution Oy. Only two sources have been shown for clarity of design, but it is obvious that this invention applies to any number, greater than or equal to two, of light sources, evenly distributed over the crown 12 around the axis Oy.
  • Convergent lenses 14 are arranged at a distance from the light sources 10A, 10B, ..., so as to collect the light rays emitted by them and to form images thereof 11A, 11B, ....
  • the lenses 14 are all identical, and they can be carried by a common support
  • the images 11A, 11B, ... are merged into a common place S, so that all the rays emitted by sources 10A, 10B, ..., and having passed through the lenses 14, all converge in this common place S.
  • the common place S therefore constitutes a secondary source of light rays resulting from the superposition of images 11A, 11B, ... from sources 10A, 10B, ....
  • the secondary source S can then serve as the main source to give birth to a lighting or signaling beam.
  • a converging lens L so that its object focus is also confused with the common place S.
  • the optical axis of the lens L is advantageously coincident with the axis Oy.
  • the lens L therefore forms an image at infinity of the commonplace S, which thus provides a beam lighting or signaling, which can be easily made to comply with regulations predetermined by choosing sources 10A, 10B, ..., of intensity appropriate to the lighting or signaling function desired.
  • the present invention makes it possible, for example, to obtain in a particularly simple manner a light beam with a clear cut, despite the use of several sources bright.
  • the lens L forms a beam of rays which are parallel, or substantially parallel. It is then possible to have downstream (in the direction of progression of the light rays) of lens L a lens G, shown in dashed lines in FIG. 1, provided with streaks or deflecting elements such as Fresnel prisms, to obtain the distribution in a known manner desired space for rays emerging from ice G.
  • the cover C thus has an edge, located in the immediate vicinity of the common place S, and therefore in the focal plane of the lens L.
  • the lens L therefore forms at infinity the image of the edge of the cover C, which constitutes the cut-off of the light beam emitted by the lens L.
  • We can advantageously plan to make the cover mobile for example mobile in rotation around of an axis perpendicular to the optical axis Oy, between two positions, a first position in which it intercepts part of the light rays constituting the secondary source for obtain a cut-off beam such as a passing beam, and a second position in which it lets pass all the light rays coming from the secondary source, to obtain a uninterrupted beam such as a driving beam.

  • light sources 10A and 10B arranged on a ring 12, which in this variant can be a flat or frustoconical ring, of axis of revolution Oy. Only two sources have been shown for clarity of the drawing, but it is obvious that the present invention applies to any number, greater than or equal to two, of light sources, evenly distributed over the crown or ring 12 around the axis Oy.
  • the optical systems forming real images of the light sources 10A, 10B, ... are portions of ellipsoids 24, arranged in a corolla around the axis Oy, in such a way that their first foci coincide with sources 10A, 10B, ..., and that their second hearths are confused between them on the axis Oy and with the hearth object of the lens L.
  • ellipsoid should be understood as designating a global surface is close to that of an ellipsoid of revolution, i.e. a surface whose section through a plane passing through the two foci is a portion of an ellipse or approaches of a portion of ellipse, but whose eccentricity can vary from one section plane to another, the surface may include areas of limited extent, the section of which deviates from that a portion of an ellipse.
  • the light rays coming from the different sources 10A, 10B, ... all converge on the commonplace S, which still constitutes a secondary source of light rays resulting from the superposition of images 11A, 11B, ... sources 10A, 10B, ....
  • the secondary source S serves as the main source to give birth, by the lens L whose object focus coincides with the secondary source S, to a lighting or signaling beam, which can be easily made to conform to a predetermined regulation by choosing sources 10A, 10B, ..., of appropriate intensity to the desired lighting or signaling function.

  • the present invention applies to any number, greater or equal to two, from light sources, distributed regularly on the crown 12 around the axis Oy.
  • converging lenses 14 are arranged away from light sources 10A, 10B, ..., so as to form real images thereof 11A, 11B, ....
  • the images 11A, 11B, ..., are again confused in a common place S, so that all the rays emitted by sources 10A, 10B, ..., and having passed through lenses 14, all converge in this commonplace S, which then constitutes the secondary source S of light rays resulting from the superposition of images 11A, 11B, ... of sources 10A, 10B, ... and which can then be used as the main source to give birth to a lighting or signaling beam.
  • the optical system used to form the beam lighting or signaling from source S consists of a reflective surface A.
  • the reflective surface R can consist of a conventional spotlight reflector lighting or signaling light, i.e. a concave surface, the secondary source S playing the role of a classic lamp.

  • This dish of revolution is arranged so that its optical axis coincides with the axis Oy of symmetry in relation to which the light sources 10A, 10B, etc. are arranged, and that its focus is confused with the secondary source S.
  • the reflecting surface R being convex, it transforms the secondary source S, formed real images of light sources 10A, 10B, ..., into a virtual object, the surface of which reflective R gives a real image, located at infinity in the case of a paraboloid of revolution, which thus provides a lighting or signaling beam, which can be rendered easily complies with predetermined regulations by choosing 10A sources, 10B, ..., of appropriate intensity for the desired lighting or signaling function.

  • light sources 10A and 10B arranged on a crown 12, which can also be a flat ring or frustoconical, axis of revolution Oy.
