Definitions

  • Multi-function projectors are known, in particular bi-function with a halogen light source which make it possible to ensure the beam with cutoff, in particular a coded beam and, when the cover is in the erased position, another type of unbroken beam.
  • this unbroken beam is generally too weak to constitute a homologous road beam so that it is necessary to provide an additional road searchlight which is lit when the cache is erased.
  • Muti-function projectors are also known, in particular bifunctional, halogenous light source homologable only for the production of an unbroken beam including a road beam, but this beam is of small width and reduced homogeneity.
  • Dual-source xenon projectors can be rated alone with a satisfactory width of the beam, but homogeneity also needs to be improved.
  • the object of the invention is, above all, to provide a multi-function, in particular dual-function, light projector for a motor vehicle which makes it possible to obtain an improved seamless function, in particular a road function, which does not require an additional headlamp and which provides a sufficient width of the beam, with good homogeneity. It is also desirable that this projector remains a relatively simple and economical embodiment.
  • the main optic is advantageously constituted by a convergent lens and the additional optics is also constituted by a convergent additional lens.
  • the additional lens may be a duplication of the central portion of the main lens,
  • the additional lens is a diverging lens.
  • the additional lens may be inserted into a notched portion of the main lens.
  • the indented portion of the main lens is located opposite the indented portion of the main reflector.
  • Each indented portion may be located in the lower zone of the reflector and the lens. Alternatively, the indented portion is located on the right or left of the reflector and the main lens.
  • the main lens and the additional lens can be made in one molded piece.
  • the cover can be formed by a single plate.
  • the erased position can be obtained by rotating the cover around its transverse edge remote from the optical axis of the main reflector.
  • the cover can also move from an optically active position to a position erased by other movements, for example by translation, especially in the plane of the cache / in a substantially vertical plane.
  • window is meant an opening in the cache of appropriate dimensions and shapes.
  • the light source may be a single-filament halogen lamp. Compared to a bi-filament lamp, this choice requires the use of a mobile cover. On the other hand, it is interesting from the optical point of view, because the bi-filament lamps generally require making a passage hole at the bottom of the mirror of impoilent dimensions, this type of lamp being much more bulky than a monofilament lamp.
  • the cache has only one active position and one erased position, so as to obtain a dual function. But it is also possible that the cache has not only an erased function, but also at least two active positions, to obtain several functions of different cleavage beams. We then obtain, for example, a tri-function or a multi-function according to the design of the cache.
  • the cover is made in two parts that can be erased separately, namely a first part closer to the optical axis of the main reflector whose erasure makes it possible to obtain a first type of road beam, and a second part, farther from the main optical axis, whose erasure with that of the first part makes it possible to obtain a beam without any other cutoff, in particular a harder road beam.
  • the cover is associated with an additional optical element disposed between the light source and the cover, said additional optical element being in the vicinity of one of the optically active edges of the cover and having at least one reflective surface capable of redirecting over the edge optically active cache light rays emitted by the source towards said cache.
  • This additional element may take the form of a plate whose front edge is attached to the optically active edge of the cover, which is substantially flat and an upwardly facing face is reflective.
  • This element can be mechanically fixed to the cache, or can be part of it.
  • This element can be referred to as "folding". This folder is designed so that it reflects the rays appropriately to the associated lens, rays that otherwise would have been lost.
  • This folder may be associated with one or other of the parts of the cache, in the case where the cache is in several parts, as will be detailed using the example of FIG. 11.
  • the cut-off beam in particular code beam, is obtained with the two parts of the cache in the active position.
  • the second part of the cover has a substantially L-shaped cross-section with two right-angled branches of different lengths, and is pivotally mounted about a transverse axis passing through the apex of the angle formed by the L .
  • This second part of the cover can occupy a first angular position in which the large branch of the L is in the active position and cooperates with the first part of the cache in the active position to give the cut-off beam; in a second angular position of the second part, the smallest L branch is in the active position when the first part of the cache is also in the active position, a space between the edges opposite the two parts and allowing the passage of light rays to strengthen a central zone of the cut-off beam. It is thus possible to obtain an AFS function that corresponds to a highway code function. This variant is particularly interesting with a light source of xenon lamp type.
  • the invention also relates to the motor vehicle equipped with at least one projector described above.
  • a light projector comprising an elliptical reflector 1 i having an internal focus Fi and an external focus Fe on an optical axis XX.
  • a light source S is placed in the vicinity of the internal focus Fi.
  • An optics formed by a convergent lens Lo is disposed in front of the reflector and the focal point of the lens coincides with or adjacent to the external focus Fe.
  • a mask M in the active position is substantially orthogonal to the optical axis XX.
  • the upper edge Mh of the cover constitutes a cutting edge and is located in the vicinity of the focus of the lens L and the external focus Fe.
  • the last useful radius Ru for the cut-off beam falls at a point 2 of the reflector 1 such that the reflected ray Ru1 arrives at the peripheral edge of the lens L.
  • the light rays falling in the zone 3 situated in front of the point 2 will give reflected rays that will not be recovered by the Lo lens.
  • the zone 3 of the reflector 1 is therefore an area which is not useful optically for the production of the cut-off beam.
  • the reflector 1 comprises an indented portion 4 in the zone 3 which is not optically useful for the cut-off beam.
  • This notched portion 4 is located, according to the example of FIG. 2, in the lower part of the reflector and has the shape of a notch open towards the front, that is to say according to the direction of propagation of the light beam. .
  • a secondary elliptical reflector 5 (FIGS. 2 and 3) is added in the indented zone 4.
  • the reflector 5 is formed by an ellipsoid portion whose concavity is turned towards the interior of the reflector 1.
  • the contour of the reflector 5 is connects to the contour of the notch 4 and opens towards the front.
  • the reflector 5 forms a kind of hump with respect to the surface of the reflector 1.
  • the secondary reflector 5 comprises an active front part 5a which is involved in producing the light beam, and a rear part 5b which is not reached by the light rays coming from the source S and which is used for connection with the main reflector 1.
  • the front portion 5a is located on an ellipsoid surface whose extension is shown in indents in Figs.3 and 6 which has the same internal focus Fi as the main reflector 1.
  • the major axis YY of the ellipsoid 6, which corresponds to the optical axis of the reflector 5, is inclined with respect to the optical axis XX of the main reflector 1.
  • the external focus Fe5 of the secondary reflector 5 is located in front of this reflector transverse distance down the axis XX .
  • the lower edge 7 of the cover M is located at the lower edge of the reflector 5.
  • the cover M is rotatably mounted about an axis extending along its lower edge 7 so as to be erasable from the active position illustrated in FIG. .3 in an erased position illustrated in Fig.6 by a 90 ° rotation from a vertical position (Fig.3) to a horizontal position (Fig.6).
  • An additional lens 8 constituting a duplication of the central portion 9 of the main lens L is disposed in front of the secondary reflector 5.
  • the focal point of the additional lens 8 coincides with the external focus Fe5 of the secondary reflector 5, or close to this focus.
  • the optical axis of the additional lens 8 is parallel to the axis XX.
  • the lens L is advantageously scalloped along a concave curve 10 in its lower part facing the secondary reflector 5.
  • the upper part of the additional lens 8 fits into this notch 10 whose shape matches it.
  • a step 11 is formed at the junction of the additional lens 8 and the main lens 9 less thick in the area considered as the lens 8. It could however provide a connection of the additional lens and the main lens without this walk 11.
  • the main lens L and the additional lens 8 may be molded in one piece, in particular transparent plastic material.
  • the lens may be glass.
  • the lens 8 is attached and fixed, in particular by gluing, to the main lens L.
  • a first function corresponding to a cut-off beam, namely a code beam, is obtained when the source S is on and the cover M is in the active position shown in FIG. 3, that is to say in the vertical position.
  • the illumination area on a screen located in front of the projector and orthogonal to the X-X axis is illustrated by the shaded area 12 of Fig.5; it is a simplified representation giving the outer contour of the illumination zone, without reproducing the isolux curves inside this zone.
  • the maximum illumination point is located substantially at the width of the zone, slightly below the upper cutoff edge 13 which comprises, in a conventional manner for right-hand traffic, a horizontal left-hand portion and a rising right-hand portion. angle of inclination determined.
  • the edge 13 is an image of the upper edge of the mask M.
  • the illumination area illustrated in Fig.7, comprises above the zone 12, a zone 14 whose isolux have not been shown.
  • the secondary reflector 5 in combination with the additional lens 8, contributes to the reinforcement of the illumination of the zone 14 and avoids the need for a complementary road projector when the source S is a halogen source with a single filament.
  • the homogeneity and the intensity of the beam are improved whatever the light source.
  • the transverse shift between the optical axis of the main lens 9 and the additional lens 8 is only a few centimeters and is not sensitive to a distance of 25m to which is usually placed the illumination control screen.
  • the additional lens 8 in the lower part of the main lens L, it could be provided on the right or left side, with a corresponding indentation in the main lens.
  • the light beam would be slightly degraded and, in addition, the right and left headlights of the same vehicle would be different.
  • FIGS. 3 to 7 has been given with a single additional lens 8. However, it would be possible to provide a plurality of recessed portions each associated with an additional lens and a corresponding complementary reflector such as 5.
  • Fig.8 shows an alternative embodiment in which the additional lens 8a is a diverging lens having, for example, an outwardly concave front face.
  • the external focus Fe5 of the complementary reflector 5 is in front of the concave face of the lens 8a, coinciding with the, or in the vicinity of, the focus of this lens.
  • the optical axis Y of the secondary reflector 5 is less inclined on the optical axis X-X because the external focus Fe5 is further forward than in the case where the additional lens 8 is convex. This results in improved efficiency.
  • the maximum illumination to be obtained for the road beam does not require a complementary projector and results from the combination of the main reflector and a light source.
  • additional optical system made with complementary reflector 5 and additional lens 8.
  • the maximum illumination area for the road function must reach 63 lux; 47 lux comes from the main reflector and the additional 16 lux come from the additional reflector system 5 with lens 8.
  • the performance of the code function will depend on the main lens L, depending on whether it is complete or not.
  • the additional lens 8 can be either integrated in the main lens L as illustrated in Fig.4, or contiguous below.

  • the main reflector 1 comprises, as in the previous case, a cutout in the non-useful part optically and the complementary reflector 5 is always connected to the main reflector.
  • the cover Ma is made in two parts respectively 15 and 16.
  • the first part 15 corresponds to the upper part and is articulated around a transverse axis passing through its lower edge in order to be able to assume an erased horizontal position illustrated in FIG. .9, or an active vertical position illustrated in Fig.11.
  • the lower part, or second part, 16 of the cover has an L-shaped section and is articulated around a horizontal transverse axis passing substantially through the top of the right angle formed by the branches 17, 18 of L.
