Definitions

  • the invention relates to a headlamp for vehicles according to the preamble of claim 1.
  • Such a headlight is known from DE 40 02 576 A1.
  • This headlight has a gas discharge lamp as the light source and a reflector, with an upper reflector area and a lower reflector area. Light is reflected from the upper reflector area as a convergent light beam, which forms a low beam. Light reflected from the upper and lower reflector areas together forms a high beam.
  • a lens is arranged behind the reflector, through which the light reflected from the upper reflector area passes.
  • a diaphragm arrangement Arranged between the reflector and the lens is a diaphragm arrangement which consists of a single diaphragm and which has an upper edge, through which a light-dark boundary of the low beam is generated.
  • the diaphragm also forms a shielding device assigned to the lower reflector region, which is between a position for Low beam and a position for high beam is switchable. In the position for low beam, light reflected from the lower reflector area is shielded by the cover and in the position for high beam light reflected from the lower reflector area can pass the cover and exit the headlight.
  • This known headlamp can thus be used for low beam and high beam, but different versions are required for right-hand and left-hand traffic, which increases the manufacturing effort of the headlamp.
  • the headlamp according to the invention with the features according to claim 1 has the advantage that it can be used for right-hand and left-hand traffic, so that only one headlamp version is required for both types of traffic.

  • FIG. 4 shows the panel arrangement in the position for low beam and left-hand traffic
  • FIG. 5 shows the panel arrangement according to a second exemplary embodiment in for right-hand traffic optimized design in a position for low beam
  • FIG. 6 shows the diaphragm arrangement according to the second exemplary embodiment in a design optimized for left-hand traffic

  • a headlight for vehicles, in particular motor vehicles, shown in FIG. 1 serves for the optional generation of a low beam and a high beam.
  • the headlight has a reflector 10, in which a gas discharge lamp 12 is inserted as a light source. During operation, an arc 13 is formed in the gas discharge lamp 12, which extends axially along the optical axis 14.
  • the reflector 10 has an upper reflector region 16 and a lower reflector region 18, it being possible for the transition between the two reflector regions 16, 18 to take place in the horizontal central plane 20 of the reflector 10 or offset upwards or downwards with respect thereto.
  • the transition between the two reflector regions 16, 18 can take place in the form of a step or a kink or also continuously, that is to say without a step or kink.
  • the upper reflector region 16 is designed so that the gas discharge lamp passes through it 12 emitted light is reflected as a convergent light beam.
  • a lens 24 is arranged after the reflector 10, through which the light reflected by the upper reflector region 16 passes.
  • the lens 24 is designed as a converging lens and has a flat surface 25 facing the reflector 10 and a convex curved surface 26 facing away from the reflector 10.
  • the curved surface 26 of the lens 24 is preferably aspherical. Reflected light is deflected by the lens 24 from the upper reflector region 16, preferably in such a way that after passing through the lens 24 it runs approximately parallel to the optical axis 14 in vertical longitudinal planes or downward in the light exit direction 22 and in horizontal longitudinal planes is scattered.
  • a translucent cover plate can also be arranged, which can be designed as a smooth plate or can be provided with optically active elements through which the light passing through is deflected.

  • the high beam emerging from the headlight in the high beam operating position is thus formed by the light reflected by the upper reflector region 16 and by the lower reflector region 18, while the low beam emerging from the headlight in the low beam operating position is formed only by the light reflected by the upper reflector region 16 .
  • the light reflected by the lower reflector region 18 can pass through the lens 24 and be deflected thereby, or it can also be provided that the light reflected by the lower reflector region 18 passes the lens 24 and is therefore not deflected by the latter.
  • optically effective elements can be provided on the cover plate, by means of which the light reflected by the lower reflector region 18 is deflected.
  • the upper reflector region 16 is optimized in such a way that the light reflected by it in cooperation with the lens 24 forms an effective low beam, while the lower reflector region 18 is optimized in such a way that the light reflected by it together with the light reflected by the upper reflector region 16 forms an effective high beam.
  • the transition between the two reflector regions 16, 18 can be continuous, that is to say stepless, or also with one step.
  • the upper reflector region 16 can be designed such that it contains ellipses or elliptical-like curves in axial longitudinal sections, that is to say the optical axis 14.
  • the upper reflector region 16 is not rotationally symmetrical, so it contains different curves in different axial longitudinal sections.
  • the lower reflector region 18 can also be designed such that it contains different ellipses or ellipse-like curves in different axial longitudinal sections and reflects light emitted by the gas discharge lamp 12 as a convergent light bundle.
  • the lower reflector region 18 can, as shown in FIG. 1, be pivoted upward from a position shown in broken lines with respect to the upper reflector region 18 with its front edge pointing in the direction of light exit 22 about an axis 35 running perpendicular to the optical axis 14 and horizontally.
