Definitions

  • the present invention relates generally automotive headlights, and more precisely a projector capable of emitting a cut-off beam, at least part of the cut presents an oblique inclination, typically at 15 °, relative to the horizontal.
  • Such a cut is for example that defined by European regulations on the subject, and includes, for a right-hand traffic direction, a left half-way horizontal and a straight half-cut raised 15 ° above of the horizontal.
  • One of the aims of such an orientation is to make projectors whose mirror has a height dimension at least equal, or even substantially greater than its width dimension.
  • FR-A-2 602 305 the description of a mirror able to cooperate with a transverse source for generate a fog beam
  • FR-A-2 602 306 the description of a mirror capable of cooperating selectively with two transverse sources for generate a passing beam and a main beam conforming to United States regulations from America, the passing beam being delimited by a cut formed by two horizontal half-planes offset in height.
  • the present invention aims to overcome these limitations of the state of the art.
  • a mirror 20 intended to project infinitely a light beam of light, this mirror receiving in its background a light source constituted by the species by the generally cylindrical filament 10 of an incandescent lamp.
  • the axis of the filament 10 is perpendicular to the optical axis of the mirror 20, which is itself perpendicular to the plane of the sheet, and the axis of the filament extends horizontally in this case.
  • each point of the mirror 20 goes generate an image of the source 10 whose orientation, in a projection plane perpendicular to the axis optics of the mirror, will depend on the coordinates of this point.
  • a first element of the approach leading to the present invention is to locate on the surface of the mirror the points which generate images of the source having the same inclination with respect to the horizontal, and in this case an inclination of 15 ° in the direction of counterclockwise rotation, so that you can then positioning these images appropriately, generating minus part of the half cut inclined at 15 ° by one standardized European passing beam.
  • FIG. 1 illustrates in back elevation the case study of a mirror 20 having a reflecting surface in the form of a paraboloid of revolution focused in the center of a transverse filament 10, and we have identified on this surface a certain number of lines of points on the surface (L N ) generating images whose major axes all have the same inclination of N degrees relative to the horizontal.
  • Bold are the lines L 15 corresponding to inclinations of source images oriented at 15 ° in one direction or the other with respect to the horizontal.
  • FIG. 2 illustrates in rear view a quarter of a mirror 20, which is constituted by a piece of paraboloid focused behind the filament 10 and laterally with respect thereto, as well as the lines L 15 of iso-inclination 15 ° images.
  • Figure 3 illustrates the horizontal generator of this quarter mirror, as well as the position of the focal point F.
  • a zone Z of the mirror bordering the line L15 will allow, with the parabolic surface described above, to generate images of the filament which in a projection screen, will rotate around their edge lateral homologous to the edge of the filament to which the focus and within angular limits located on either side otherwise the value of 15 °, these images being located at right of the screen reference center.
  • Such a surface is therefore suitable for initiating the upward cut at 15 °, and at the same time to create a spot of concentration immediately below this cut, as we will see in detail later in an embodiment of the present invention.
  • the cylindrical filament 10 which can typically consist of either the transverse filament a H3 standard lamp mounted axially at the bottom of the mirror, either of the axial filament of an H1 or H7 lamp laterally mounted in the mirror.
  • the high and low vertical generators, 20h and 20b respectively, of the mirror 20 are designed to so as to bring all the images of the filament 10 below and essentially flush with the horizontal level, so as to be able to generate, as we will see in detail further on, clear cut beams of good quality.
  • these vertical generators are constructed by drawing lines D1 tangent to the surface of the filament 10, these straight lines being on the side back of the filament with regard to the generator superior 20h, and being on the front side of the filament for the generator 20b.
  • each of these lines D1 corresponding to a light ray emitted by an edge of the filament 10, are respectively associated with lines D2 parallel to the optical axis y-y of the mirror, which itself is substantially parallel to the axis of the vehicle.
  • Each generator is built up close close, starting from the bottom of the mirror 20 which is fixed at a predetermined dimension relative to the filament, from different lines TG obtained, to define a curved line, which will be called in the following "Evolutionary generator” insofar as it does not does not have a fixed hearth, but a set of hearths that evolve gradually as you move along said generator.
  • Evolutionary generator insofar as it does not does not have a fixed hearth, but a set of hearths that evolve gradually as you move along said generator.
  • FIG. 6 illustrates the arrangement of the images, aligned below and flush with the horizontal plane, obtained with a mirror 20 having the generator vertical described above and a generator horizontal with a certain defocus by compared to source 10. These images define a very good horizontal cut.
  • the different zones have relatively similar widths, and typically between 6 and 13 mm, and are characterized for the essential by horizontal generators different, defined according to the lateral offset and of the desired spread of light.
  • central zones 215 and 225 which generate filament 10 images that are horizontal or very slightly inclined with respect to the horizontal, are intended to perform the horizontal cut over an area important.
  • Their horizontal generator is advantageously a straight line.
  • zones 214, 226 either made up of pieces of satellite dishes, or with horizontal and vertical generators of different hearths (the position of the hearth of the generator horizontal determining in particular the positioning symmetrical or dissymmetrical images by relative to the axial vertical plane passing through the center of projection screen reference), either again and preferably with a horizontal generator parabolic and an evolving vertical generator such as described above with reference to Figure 4.
  • Figures 8 and 9 illustrate the case where the area 214 is a surface generated by dragging the vertical generator of Figure 4, in such a way that it remains parallel to the plane y0z, on a generator horizontal formed by a piece of parabola whose hearth F is located behind filament 10, and to the right from its center.
  • Figures 11 and 12 illustrate the case where the piece of parabola defining the generator horizontal zone 214 has an offset O'y 'axis laterally with respect to the main axis 0y of the mirror, so that the focal point F is brought closer to the lateral end of the filament 10 opposite the side in which is the area 214, while the generator vertical is always of the type illustrated on the figure 4.
  • the resulting images are illustrated on the Figure 13, and we observe that the lateral shift of the focus F creates an image shift on the side of the half-cut inclined Hc, as well as a spot of concentration below this half-cut Hc, so as to better light the side of the road.
  • Another solution is to create area 214 with a surface extending in continuity with those adjacent areas, and planning in the area of the closing glass which is homologous to zones 214, 226 of the mirror of the prisms and if necessary of the streaks having the same function as those projected on the mirror as indicated above.
  • the other areas of the mirror 20 in FIG. 7 are used to provide light distribution satisfactory light in the different areas of the beam.
  • we adapt the horizontal generators of these zones which are same preference for the upper zone and for the lower area so as to avoid discontinuities likely to cause optical defects.
  • the other areas may possibly present, depending on the function which is assigned to them, surfaces of different types, and in particular surfaces derived from the teachings of documents FR-A-2 536 502, FR-A-2 536 503, FR-A-2 602 305, FR-A-2 602 306, FR-A-2 609 146, FR-A-2 609 148, FR-A-2 639 888, FR-A-2 664 677 and FR-A-2 710 393, on behalf of the Applicant.
  • Figures 14 to 22 illustrate by sets of isocandela curves the beam parts that are by example generated by zones 214, 213, 212, 211, 216, 217, 218, 219 and 215 of the mirror of Figure 7, while Figures 23 and 24 illustrate the shape obtained in superimposing the beam parts of the Figures 14 to 17 and the beam parts of Figures 18 at 21.
  • Figure 25 illustrates the appearance of the beam generated by the upper half of the mirror Figure 11, while Figure 26 illustrates the pace of the beam part generated by its half lower.
  • Figure 27 illustrates the beam pattern overall obtained. We observe that it is a beam having all the qualities required in terms of width, thickness and concentration in the axis of the road.
  • the present invention allows to achieve, through the use of a transverse source and to the different areas as described above, mirrors for European passing beam whose width is significantly less than height.
  • the ratio between height and width can be between 1.2: 1 and 4: 1.
  • the present invention also applies to a projector according to another concrete embodiment of the invention, which will now be described in reference to Figures 28 to 31.
  • Figures 28 to 30 show a projector which mainly includes a source luminous 10, such as the filament of a lamp with incandescent or arc of a discharge lamp, a first mirror 40, a mask 30, a second mirror 20 and a mirror 50.
  • a source luminous 10 such as the filament of a lamp with incandescent or arc of a discharge lamp
  • first mirror 40 such as the filament of a lamp with incandescent or arc of a discharge lamp
  • a first mirror 40 such as the filament of a lamp with incandescent or arc of a discharge lamp
  • a first mirror 40 such as the filament of a lamp with incandescent or arc of a discharge lamp
  • a first mirror 40 such as the filament of a lamp with incandescent or arc of a discharge lamp
  • a first mirror 40 such as the filament of a lamp with incandescent or arc of a discharge lamp
  • mask 30 such as the filament of a lamp with incandescent or arc of a discharge
  • the projector also includes, as in the case previous and not illustrated but classic in self, a box and various auxiliary fittings for mounting, electrical connection, etc.
  • the source 10 is positioned on the high focus F1 or in its immediate vicinity. Preferably, in the case from an elongated source, this extends horizontally and perpendicular to the optical axis AO as we go define further.
  • the mask 30 is an opaque flat plate, produced for example in sheet metal, and has an opening 31 whose shape, preferably rectangular and long axis perpendicular to the optical axis AO, is illustrated on the figure 3.
  • the plane of the mask passes through the low focal point F2 of the mirror 40 or in its immediate vicinity, and is positioned in such a way that the F2 focus is located at the right of the opening 31. It will be noted here that the preferred orientation from the actual source 10 as described above is the more suitable for homogeneous "filling" aperture 31 with light reflected from the mirror 20.
  • the mirror 20 is a beam-forming mirror lighting which is for example similar to half bottom of the mirror described with reference to Figure 7. It defines a main optical axis AO and which is suitable for cooperate with the light passing through the opening 31 of the mask to form the European passing beam.
  • a mask 30 with an opening 31 including the major axis extends transversely to the optical axis AO of the projector allows to generate beams altogether satisfactory with a mirror 20 whose height is important, and typically at least as large as its width.
  • the virtual source is plane allows to build at the level of the mirror 20 a optical surface which generates a clear cut beam in a simpler way than with the source three-dimensional view of the previous embodiment.
  • a planar source makes this form invariable, and in this case in the form of a parallelogram, whatever the observation point.
  • FIGS. 28 to 30 we have shown a concrete embodiment of the mirror 20 of a headlight of the type shown in FIGS. 28 to 30. It is subdivided into two zones, namely a zone upper 20a and a lower area 20b, the height of the zone 20b preferably being substantially greater than that of zone 20a.
  • these subzones are formed by the orthogonal projection of striations such as cylindrical striations of axes vertical, on a base surface which is for example type defined in documents FR-A-2 536 502 and FR-A-2 536 503.
  • Such a projected stripe mirror is described in particular in document FR-A-2 710 393.
  • the upper zone 20a generates, with in this case seven individual subzones 21a to 27a, beam portions of large width, with projected streaks with a relatively radius of curvature low.
  • This area close to the defined virtual source through opening 31, in effect generates images relatively large from the source, hardly conducive to creation well defined areas of concentration in the beam, but on the contrary conducive to giving it the desired width.
  • the lower region 20b of the mirror which generates smaller images of the source, on the contrary consisting of sub-areas 21b to 25b ensuring spreading less important, or even practically zero, so as to create in the beam a spot of appropriate intensity concentration in the axis of the road.
  • relatively large sub-area 24b is produced in accordance with the invention to create on a extent limited to the half-cut at 15 °, for example in using as described above a surface generally parabolic whose focus is judiciously positioned.
  • the projector makes it possible to generate a beam quite satisfactory especially in terms definition of cut.
  • sub-area 24b which defines the inclined half cut extends between the edge lower of the mirror and a level located not at the source height, but noticeably below this can of course also be implemented, for one of the zones 214, 226 or for both, in the embodiment of Figure 7. This avoids work with more inclined images of the filament as generated by points located near the median horizontal plane.
