Definitions

  • the present invention relates generally to motor vehicle headlamps, and it relates more particularly to improvements made to headlamps capable of emitting a cut beam, for example a European type passing beam or an anti-fog beam, and comprising for this purpose a lamp whose filament emits freely all around it and cooperates with a smooth reflector with complex surface designed to form the cut by itself.
  • a cut beam for example a European type passing beam or an anti-fog beam
  • the invention relates to improvements to projectors of this type, the smooth surface of the reflector is further designed to give the beam, without the intervention of the closing glass, a substantial width. This avoids the well-known optical defects which appear in particular when a strong lateral deviation is required from a closing glass inclined relative to the vertical.
  • This document describes a reflector, a bottom zone of which is modified to spread the light laterally, while lateral zones are produced in a conventional manner.
  • the width of the beam is obtained by acting essentially on the bottom zone of the complex reflector. This is not always compatible with the presence of a direct light cover placed in front of the lamp. Indeed, if the beam is given the required width by strengthening the convergence of the rays reflected by the background, a large proportion of these rays will be intercepted by this mask and not participate in the beam. The light output is thereby reduced.
  • the present invention aims to overcome the drawbacks of the prior art and to provide a beam projector of the above type in which, by the sole intervention of the reflector, retaining an essentially continuous and smooth surface, a substantial beam widening is obtained not only horizontally, but if necessary essentially parallel to an inclined part of the cut, and in particular along the angle of raising of the cut along the inclined half-cut of a standardized European passing beam.
  • the invention aims to propose a new reflector design in which the bottom zone and the edge zone or zones are produced in a conventional manner, while intermediate zones ensure the enlargement in the aforementioned manner.
  • a secondary object of the present invention when the lamp used comprises a direct light cover placed at the front thereof, is to minimize the quantity of rays which, after reflection on the reflector, are directed towards this cover and therefore do not participate in the formation of the beam.
  • the present invention relates to a motor vehicle headlamp having the features of claim 1.
  • a dipped projector comprising a lamp (of contours not shown) provided with an axial filament 100 modeled by a cylinder of length 2 l and radius r, arranged parallel to the optical axis Ox so that its lower surface is essentially tangent to this axis, a reflector with complex surface 200 and a closing glass 300.
  • the reflector is divided into six zones 201 to 206 each having a clearly defined role on the optical plane, these zones being themselves continuous in second order and connecting together, according to the planes as illustrated, also with continuity in second order (with the exception of connections between zones 204, 205 and 203, 206, respectively, where continuity is only achieved at first order).
  • each of the zones 201 to 206 is produced only in part in accordance with the equations set out in the above-mentioned patent applications, being modified in certain regions with respect to these equations, as will be seen. see now with reference to Figures 2a to 2c.
  • Each of these figures is a view in horizontal section through the area 205, all the light rays being projected vertically in the horizontal plane of this section.
  • Figure 2a illustrates the case of a projector according to the French patent No. FR-A-2 536 502 cited above.
  • all the rays reflected by the zone 205 circulate approximately in a vertical plane parallel to the optical axis 0x; the delivered beam is therefore relatively narrow and its width will be given to it by the closing glass, either prismably or striated.
  • FIG. 2b and 2c illustrate the principle of the invention.
  • the zone 205 here comprises an interior sub-zone 205i and an external sub-zone 205e whose surfaces are identical to the surface of the zone 205 in FIG. 2a, except that the basic focal distances of these two zones are different . It is further defined an intermediate zone 205m whose profile deviates from the known surface, so as to give the reflected rays either a determined convergence (FIG. 2b), or a determined divergence (FIG. 2c).
  • the various sub-areas have continuous second order surfaces, and furthermore are connected to each other, in transition planes, with second order continuity. It should be noted here that the differences between the known surface and the surface modified in accordance with the invention have been greatly exaggerated for the sake of clarity.
  • the large width conferred on the part of the beam generated by the area 205 is obtained on the one hand by respecting the inclined half-cut generated in itself by this area, but especially by deflecting the rays luminous at the level of the intermediate zone not horizontally, but in a plane parallel to the cut.
  • the "V" cut of the beam is defined over a large lateral extent.
  • each zone 201 to 206 comprises an interior sub-zone, respectively 201i to 206i, a sub-zone intermediate, respectively 201m to 206m, and an outer subzone, respectively 201e to 206e.
  • the interior and exterior sub-zones are produced in accordance with the above equations, however using in each zone different basic focal distances for the internal sub-zone and the external sub-zone.
  • the sub-areas 201i, 201e and 202i, 202e are portions of paraboloids of revolution, having either the same focal point located on the optical axis directly above the center of the filament, or two distinct focal points located respectively in the vicinity of the two axial ends of the filament, and also having different focal distances two by two.
  • the interior zones 203i to 206i and 203e to 206e are the areas with complex surface defined mathematically in the patent applications cited above, and therefore have the properties stated therein.
  • each of the intermediate sub-areas 201m to 206m locally modifies the profile of the area considered to give the beam the required width, as has been seen above for the area 205m. More specifically, each intermediate subzone has the property of making a continuous second order connection between the associated interior and exterior subzones, offset from one another, by presenting a profile for two for this purpose. reverse curvatures separated by a line of inflection, as shown in Figures 2b and 2c. Each intermediate subzone also has the property of connecting with second order continuity with the intermediate subzone located immediately above or below.
  • each intermediate sub-zone has the function of deflecting the light rays in a direction essentially parallel to the part of the cut defined by the zone in question, so that the various parts of said cut are defined over a large area. extended in width.
  • the intermediate sub-areas 203m and 204m of the complex surface areas 203 and 204 widen the beam portion considered horizontally below the horizontal half-cut hH of a standardized European passing beam, while the sub- intermediate zones 205m and 206m of the areas with complex surface 205 and 206 widen the portion of beam considered below the half-cut inclined at 15 °, denoted Hc, by deflecting the rays parallel to this half-cut.
  • the intermediate sub-areas 201m and 202m are delimited by arcs of circles centered on the center O of the reflector, while the intermediate sub-areas 203m and 204m are delimited by vertical line segments and the intermediate sub-areas 205m and 206m are delimited by line segments making an angle ⁇ with the vertical, that is to say perpendicular to the inclined half-plane of cut Hc. Furthermore, the intermediate sub-zones located on the same side of the optical axis are all located in the extension of one another as illustrated.
  • y G is the distance between the axis 0x and the inner edge of the group of intermediate sub-areas 201m, 203m and 205m located to the left of the optical axis; y GM is the distance between the axis 0x and the center of the said group ("center” means the vertical straight line or inclined, or the portion of a circle, where the inflection of each of the intermediate subzones is found); y GL is the distance between the center O and the outer edge of the group of intermediate sub-areas 201m, 203m and 205m; y D , y DM and y DL have the same meanings as y G , y GM and y GL , for the intermediate sub-zones on the right in FIG.
  • f G , f C and f D are the basic focal distances of the left (sub-areas 201e, 203e and 205e), central (sub-areas 201i to 206i) and right (sub-areas 202e, 204e and 206e) of the reflector;
  • a GL and A GM are parameters which characterize the extent of the deformation of the reflector at the level of the intermediate left sub-areas 201m, 203m and 205m;
  • a DL and A DM are identical parameters, but for the intermediate right sub-areas 202m, 204m and 206m.
  • the parameters of dimensions in "y" defined above and the focal length f G are first chosen, then the importance of the width to be given to the beam, represented, is then chosen.
  • l represents the half-length of the filament
  • ⁇ 1 is equal to y /
  • ⁇ is equal to z /
  • the values taken by the parameters ⁇ , ⁇ ', y L , y M and f0 appearing for the first time in this equation vary according to the value of the y coordinate on the y′Oy axis, and are indicated in the following table I:
  • ⁇ ⁇ (y2 + z2)
  • FIGS. 3a to 3g show, in the form of images of the filament 100 on a standardized projection screen [H, h, v], the light distribution obtained with the various sub-areas of the reflector as described in detail below the correspondence between each of these figures and the sub-area (s) considered.
  • the intermediate zones 201m and 205m widen the considered portion of the beam not laterally along hh, but indeed along the inclined half-cut Hc. It is therefore extended on the side with a substantial extent and a definition which remains excellent. In practice, this translates into an increase in the range of the dipped headlight at the level of the lower side, for greater driving comfort, as well shown in FIG. 4, which illustrates the light distribution given by the whole of the reflector, also in the form of images of the filament projected on [H, h, v].
  • FIG. 5 shows a front view of a reflector according to the present invention, capable of emitting an anti-fog beam, that is to say limited by a cut defined by two horizontal half-planes both located at the same level.
  • the reflector 200 comprises a central zone 210, two intermediate zones 220, 230 and two external zones 240, 250.
  • the intermediate zones 220, 230 are constructed in the same way as the sub-zone 205m in FIGS. 2b and 2c. More precisely, using the same parameters as for the surface of the reflector of FIGS. 1a and 1b, the equation of the entire surface of the reflector according to this second embodiment is identical to equation (11) set out above. .
  • FIGS. 6a to 6d have illustrated, by images of the filament generated by the bare reflector and projected on a standardized screen [H, h, v], the light distribution obtained with each of the zones of this reflector.
  • FIG. 6a corresponds to the central part 210 of the reflector
  • FIG. 6b corresponds to the left intermediate zone 220
  • FIG. 6c corresponds to the right intermediate zone 230
  • FIG. 6d corresponds to the external zones 240 and 250.
  • FIG. 7 illustrates, for its part, by a set of isocandela curves in this same projection screen, the light distribution obtained with the whole of the reflector.
  • Projectors comprising a lamp (not shown), a reflector 200 and a front lens 300, in this case a lens arranged at an angle, have been illustrated in the horizontal sections of FIGS. 8a to 8c.
  • a direct light cover 110 arranged so that no light ray emitted by the filament can directly reach the lens 300.
  • Such a cover in the general form of a cylinder closed at its end remote from the lamp, has as its object, so known, to prevent rays from coming out of the projector above the cut-off. Any dazzling of oncoming conductors is thus avoided.
  • the reflector is produced in accordance with French patent application No. 2 609 148, that is to say that it has a background different from that of a projector with a conventional complex surface and intended to modify the convergence of the light rays reflected by said background.
  • the bottom F is divergent, which causes at the level of the closing glass large mixtures between the images generated by the background and those generated by the edges B of the reflector (more precisely in the area 300a of ice). It is thus impossible to ensure using said glass a selective treatment of the various parts of the beam, for example large images (coming from the background) giving the beam its width and thickness and small images (coming from the edges). defining the beam concentration spot.
  • FIG. 8c A reflector according to the present invention is illustrated in Figure 8c. It can be observed that, since the reflector is modified not at the bottom F but in intermediate regions I between the bottom F and the edges B.
  • Such a solution combines the advantages of the solutions known in FIGS. 8a and 8b, without having any the disadvantages: there is practically no mixing between large images of the filament generated by the background and the intermediate zones and the small images generated by the edges, and at the same time the mask of direct light does not obscure substantially any ray. More precisely, the converging rays reflected by the modified zones I are sufficiently distant from the cover to bypass the latter (rays R I in FIG. 8c).
  • the invention is applicable to headlights whose reflector does not have the same lateral extent on one side and the other of the lamp, as in the case of FIG. 8c.
  • the reflector may have only one edge zone (for example, in FIG. 1b, the sub-zones 201e, 203e and 205e or else the opposite external sub-zones may not exist, and in FIG. 5, one of the zones 240 and 250 may not exist.
