Definitions

  • the present invention relates generally motor vehicle headlamps, and more precisely a projector capable of transmitting breaking beam, of which at least part of the cut has an oblique inclination, typically at 15 °, with respect to the horizontal.
  • Such a break is for example that defined by European regulations in this area, and includes, for a direction of traffic on the right, a half-cut on the left horizontal and a half straight cut raised by 15 ° above from the horizontal.
  • Such an orientation is intended in particular to to make projectors whose mirror presents a dimension in height at least equal, or even substantially greater, in its width dimension.
  • FR-A-2 602 305 describes a description of a mirror adapted 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 cross-sectional sources for generating respectively a passing beam and a road beam in accordance with the regulations of the United States America, the passing beam being delimited by a cut formed by two horizontal half-planes offset in height.
  • FR 2657680 discloses a projector with a transverse source and a mirror whose surfaces generate images having all possible directions. An oblique cut is obtained by positioning these images along the line to train.
  • the present invention offers a vehicle headlamp automobile as defined in claim 1.
  • a mirror 20 for projecting to infinity a light beam of light, this mirror receiving at its bottom a light source consisting of the species by the generally cylindrical filament 10 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 leaf, and the axis the filament extends in this case horizontally.
  • each point of the mirror 20 is generate an image of the source 10 whose orientation, in a projection plane perpendicular to the axis optical mirror, will depend on the coordinates of this point.
  • a first element of the approach leading to the The present invention consists in locating on the surface of the mirror the points that 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 anticlockwise rotation, so that positioning these images appropriately, least part of the half-cut inclined at 15 ° of a standardized European passing beam.
  • FIG. 1 illustrates in a rear elevational view the school case of a mirror 20 having a reflective surface in the form of a paraboloid of revolution focused in the center of a transverse filament 10, and it has been identified on this surface.
  • a certain number of lines of points of the surface (L N ) generating images whose major axes all have the same inclination of N degrees with respect to the horizontal.
  • lines L 15 are lines L 15 corresponding to inclinations of images of the source oriented at 15 ° in one direction or the other with respect to the horizontal.
  • FIG. 2 illustrates, in the rear view, a quarter of a mirror 20, which consists of 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 generatrix of this quarter mirror, as well as the position of the focus F.
  • a zone Z of the mirror surrounding the line L15 will allow, with the above-described parabolic surface, to generate images of the filament which, in a projection screen, will rotate around their edge homologous side of the filament edge on which the focus and within angular boundaries located on both sides the value of 15 °, these images being located at right of the reference center of the screen.
  • Such a surface is therefore suitable for initiating the ascending cut at 15 °, and at the same time to create a concentration spot immediately below this cut, as it is will see in detail later in an embodiment concrete of the present invention.
  • FIGS. 4 and 5 which illustrate a mirror / filament set that we are going to apply the cut-off according to the invention, we have represented the cylindrical filament 10, which can typically be made of either the transverse filament a standard lamp H3 mounted axially at the bottom of the mirror, the axial filament of an H1 or H7 lamp mounted laterally in the mirror.
  • Vertical generators high and low, respectively 20h and 20b, of the mirror 20 are designed to way to bring all the images of filament 10 underneath and essentially flush with the horizontal level, in order to be able to engender, as will be seen in detail further on, clusters net cut of good quality.
  • these vertical generators are constructed by drawing straight lines D1 tangent to the filament surface 10, these lines lying on the back of the filament with respect to the generator upper 20h, and lying on the front side of the filament for the generator 20b.
  • each of these lines D1 corresponding to a light beam emitted by an edge of the filament 10, are respectively associated straight 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 from close to near, from the bottom of the mirror 20 that is fixed to a predetermined dimension with respect to the filament, from different TG lines obtained, to define a curved line, which will be called in the following "Evolutionary generator” in so far as it does not not have a fixed focus, but a set of hearths which evolve progressively as one moves along said generator.
  • These generators are distinguished in this respect from fixed-focus generators, that is to say parabolic, described above.
  • Figure 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 some defocusing by to the source 10. These images define a horizontal cut of very good sharpness.
  • FIG. a concrete embodiment of a mirror defined with the vertical generator described above with reference to Figure 4, but likely to generate by itself, that is without the intervention of ice cream closure, a European-type passing beam having the required horizontal width. It is generated by dividing the mirror 20 into different areas as shown in Figure 7.
  • the mirror has a half upper 21 and a lower half 22, which comprise each nine areas, respectively 211 to 219 and 221 to 229.
  • the different zones have relatively similar widths, and typically between 6 and 13 mm, and are characterized for the main thing by horizontal generators different, defined according to the lateral shift and of the desired spreading of the light.
  • central zones 215 and 225 that generate images of filament 10 that are horizontal or very slightly inclined to the horizontal are intended to realize the horizontal cut on an extent important.
  • Their horizontal generatrix is advantageously a straight line.
  • the zones 214 and 226 are those which are designed according to the principles explained above with reference to FIGS. 1 to 3, and respectively encompass the greater part of two iso-inclination lines L 15 so as to generate images of the filament which are parallel or moderately inclined with respect to the typical 15 ° half-cut of a European passing beam.
  • zones 214, 226 consist of pieces of parables, or with horizontal and vertical generators of different homes (the home position of the generator horizontal determining in particular the positioning symmetrical or otherwise asymmetrical images by relative to the axial vertical plane passing through the center of reference of the projection screen), ie again and preferably having a horizontal generatrix parabolic and a scalable vertical generator such as described above with reference to FIG.
  • Figures 8 and 9 illustrate the case where the zone 214 is a surface generated by dragging the vertical generator of Figure 4, in such a way that it stays parallel to the plane y0z, on a generator horizontal constituted by a piece of parabola whose F hearth is located behind the 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 of zone 214 has an O'y axis offset laterally with respect to the main axis 0y of the mirror, so that the focus F is brought closer to the lateral end of the filament 10 opposite the side in which is zone 214, while the generator vertical is always of the type illustrated in the Figure 4.
  • the resulting images are illustrated on the Figure 13, and it is observed that the lateral shift of the focus F creates a shift of images on the half-cut side inclined Hc, as well as a concentration spot below this half-cut Hc, so as to better illuminate the side of the road.
  • zone 226, having the same role, located in the lower half of the mirror.
  • zone 226, F homes positioned differently, one being able to find for example at the right of a point located between the center of the filament and one of its edges, and the other may be outside this same edge.
  • the area 214 can be expected to realize the area 214 by giving him a base area located in the continuity, and with the same equations, as the surfaces adjacent areas of the mirror, as we go describe further, and by applying on these surfaces of base, by projection along the Oy axis, elements correcting optics such as prisms and the case appropriate streaks to position the images as indicated.
  • Another solution is to make 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 where appropriate streaks having the same function as those projected on the mirror as indicated above.
  • the other zones of the mirror 20 of FIG. used to ensure a light distribution satisfactory light in the different areas of the beam.
  • central areas are 215, 225 present the vertical generator as described with reference to FIG. 2, the other zones may possibly present, depending on the function that assigned to them, surfaces of different types, and including 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, in the name of Applicant.
  • Figures 14 to 22 illustrate by sets of curves isocandela the beam parts that are by example generated by the zones 214, 213, 212, 211, 216, 217, 218, 219 and 215 of the mirror of Figure 7, while FIGS. 23 and 24 illustrate the shape obtained in superimposing respectively the beam portions of Figures 14 to 17 and the beam portions of Figures 18 at 21.
  • Figure 25 illustrates the pace of the game of beam generated by the upper half of the mirror of Figure 11, while Figure 26 illustrates the pace of the beam part generated by his half lower.
  • Figure 27 illustrates the pace of the beam globally obtained. It is observed that this is a beam having all the qualities required in terms of width, thickness and concentration in the axis of the road.
  • the present invention enables to achieve, through the use of a cross-sectional source and the different areas as described above, mirrors for European passing beam whose width is substantially less than the 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 that mainly includes a source 10, such as the filament of a lamp incandescence or the arc of a discharge lamp, a first mirror 40, a mask 30, a second mirror 20 and an ice cream 50.
  • a source 10 such as the filament of a lamp incandescence or the arc of a discharge lamp
  • the projector also includes, as in the case previous and in a way not illustrated but classic in self, a housing and various auxiliary fittings for mounting, electrical connection, etc.
  • the mirror 40 is of the ellipsoidal, long axis type essentially vertical, and has a first F1 focus or high fireplace and a second F2 fireplace or low fireplace.
  • the source 10 is positioned on the high focus F1 or in its immediate vicinity. Preferably, in the case of 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, made for example 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 low focus F2 of mirror 40 or in its near vicinity, and is positioned in such a way that the focus F2 is located at the right of the opening 31. It will be noted here that the preferred orientation of the actual source 10 as described above is the more suited to "fill" seamlessly the opening 31 with the light reflected by the mirror 20.
  • the mirror 20 is a beam forming mirror lighting that is for example similar to half lower 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 mask to form the European passing beam.
  • the virtual source is plane allows to build at mirror level 20 a Optical surface that generates a net cut-off beam in a simpler way than with the source three-dimensional of the previous embodiment.
  • a plane source makes this form invariable, and in this case in the form of a parallelogram, whatever the observation point.
  • the axial vertical section of the mirror 20 can be in this case a simple piece of parable whose home Fb is placed at the level of front edge (that is, the closest to the ice 50) of the opening 31 of the mask 30, which has the effect to bring all the images from the virtual source underneath and flush with the horizontal plane.
  • FIGS. 30 there is represented a concrete embodiment of the mirror 20 a projector of the type shown in FIGS. 30. It is subdivided into two zones, namely a zone upper 20a and a lower zone 20b, the height of zone 20b is preferably substantially greater than that of zone 20a.
  • Each of these areas is subdivided into sub-areas side-by-side, each sub-zone being suitable for generate a beam part whose position and width in the beam are well controlled.
  • these subareas are formed by the orthogonal projection of streaks such as cylindrical axes striations vertically, on a base surface which is, for example, type defined in FR-A-2 536 502 and FR-A-2 536,503.
  • Such a projected streak mirror is described in particularly in FR-A-2 710 393.
  • the upper zone 20a generates, with in this case seven individual sub-areas 21a to 27a, beam sections of large width, with Projected streaks with a relatively large radius of curvature low.
  • This area close to the defined virtual source by the opening 31, generates images relatively large source, unlikely to create well-defined areas of concentration in the beam, but on the contrary conducive to giving it the desired width.
  • the lower zone 20b of the mirror which generates smaller images of the source, is instead consisting of sub-areas 21b to 25b providing a spreading less important, if not virtually zero, of way to create in the beam a spot of concentration of appropriate intensity in the axis of the road.
  • sub-area 24b which is relatively large, is performed in accordance with the invention to create on a limited extent the half-cut at 15 °, for example in using as described above a surface generally parabolic whose focus is judiciously positioned.
  • the projector can generate a beam quite satisfactory especially in term cut definition.
  • sub-area 24b defines the inclined half-cut extends between the edge bottom of the mirror and a level not located at the height of the source but substantially below this one, can of course be implemented also, for one of the zones 214, 226 or both, in the embodiment of Figure 7. This avoids work with more inclined images of the filament as they are generated by points located near the median horizontal plane.
