Definitions

  • the invention relates to a headlamp for vehicles with a cup-shaped reflector, with a dish-shaped reflector associated light source, with one between the light source and a lens arranged and to produce several dimmed light figures serving aperture device, which is a fixed aperture for high beam and a first adjustable aperture for asymmetric low beam.
  • Such a headlamp for vehicles is known from EP 0 723 108.
  • the cup-shaped reflector is designed ellipsoidal, and between the reflector and the lens are arranged two apertures.
  • One aperture is fixed running and has a bezel edge for high beam, while the other Aperture is adjustable and has a bezel edge for asymmetrical light.
  • the two panels are made plate-shaped, with the fixed aperture and the other panel in its active position transverse to the light exit direction runs.
  • the adjustable aperture is adjustable about an axis adjacent and runs parallel to the fixed aperture, and dominates in its active position the bezel edge of the fixed bezel.
  • it is an asymmetrical one Light can be generated for right and left traffic. This is by pivoting the adjustable aperture in two positions possible. The aperture swings around an axis extending in the light exit direction.
  • To the adjustable aperture to move into the four positions described above are one or several complex built adjusting necessary. Besides, one is exact positioning of the aperture at the four possible settings not for sure.
  • headlights for vehicles has a fixed aperture a bezel edge for high beam and an adjustable Aperture an aperture for asymmetric dipped beam.
  • the adjustable Aperture is mounted on the fixed panel pivotable about an axis. The axis is parallel to the optical axis of the reflector and by a lateral area of the fixed aperture through.
  • a headlight for vehicles has become known where a fixed aperture with a bezel edge for asymmetric Light and an adjustable aperture between a reflector and a lens are arranged. Both panels are plate-shaped and run transversely to the light exit direction.
  • the adjustable aperture is pivotable about an axis, which passes through a lateral portion of the fixed aperture. In the inactive position of the adjustable aperture runs below its diaphragm edge the bezel edge of the fixed bezel, while the adjustable bezel in their active position together with the fixed aperture one Aperture edge for symmetrical light has.
  • the object of the invention is now that described in the preamble To design headlights for vehicles such that both high beam and asymmetrical light (for right and left traffic) as well as between High beam and symmetrical light is switchable and still the aperture for Symmetrical light is adjustable only in two positions.
  • a second Adjustable diaphragm of the diaphragm device for generating a symmetrical Light in the active position of the first panel is used, and, in the light exit direction seen is adjustable in an area adjacent to the first panel area, the serves to generate the far-reaching beams of light of asymmetric light, wherein the first and second aperture in their active position for generating a Light-dark border for the symmetrical light a common aperture edge and the second panel with its lower edge to a Aperture edge portion of the first aperture adjacent.
  • the adjusting device of the first diaphragm can be made simple because only two settings are needed.
  • the second aperture is only in its active Position, for example, if a vehicle for right-hand traffic temporarily in a country for left-hand traffic comes. In the active position of first aperture, then symmetric light exists instead of the asymmetrical light. In the inactive position of the first aperture, the second aperture remains in their Standing position and thus stands in the high beam. Nevertheless, the second affects Aperture for the high beam not disturbing because they are in the light exit direction only very narrow is executed.
  • the second aperture rod-shaped and rectangular in cross section is designed and narrow Side surfaces transverse to the light exit direction.
  • a rod-shaped aperture is inexpensive to produce from a sheet.
  • the aperture device is simple when the first, second and the fixed aperture in its main extension transverse to the optical axis of Reflectors run, with the first and second aperture in its inactive position are arranged below the diaphragm edge of the fixed aperture.
  • the fixed aperture can be designed so large that they with their outer edge is attached to the front edge of the reflector. Thereby forming the fixed bezel and the reflector a stable unit.
  • the panels are exactly positioned to each other, if the first and the second Aperture are adjustably mounted on the fixed panel.
  • the panels form thus a fixable to the reflector assembly.
  • the first and second aperture are spaced apart Axes are pivotable, which are parallel to the optical axis and through go through a lateral area of the fixed aperture.
  • building the aperture device very compact, especially if the second Aperture is arranged between the first and the fixed aperture.
  • the Aperture device is inexpensive to produce when the first aperture through an electric actuator and the second aperture by a manually operable Detent device are pivotable in an active and inactive position.
  • the Manual locking device for the second aperture is useful, as these are usually used only very rarely.
  • the headlight for vehicles consists of a projection module, which in a headlight housing (not shown) can be used.
  • the projection module has an ellipsoidal reflector (1).
  • the reflector is off Magnesium die-casting is produced and carries the by a gas discharge lamp formed light source, which is arranged in a focal point of the reflector (1).
  • On the back of the reflector (1) is an electrical connector (14) and a retaining ring (15) for the gas discharge lamp is arranged.
  • the reflector (1) carries at its front edge (16) a table-shaped lens holder (17). Of the Lens holder (17) is connected to the free end of his table legs on the front Edge (16) of the reflector attached by screws. In a central opening of the lens holder, a lens (18) is arranged.
  • One between the lens (18) and the light source (2) arranged aperture device has a fixed Aperture (3), a first adjustable aperture (4) and a second adjustable aperture (5).
  • the fixed panel (3) and the first panel (4) are plate-shaped and made of sheet metal.
  • the fixed panel (3) is with its outer circumferential edge attached to the front edge (16) of the reflector (1).
  • the fixed diaphragm (3) has a downwardly bent diaphragm edge (9) for high beam on.
  • the first adjustable aperture (4) is also plate-shaped and made of sheet metal.
  • the first aperture is used to generate a Asymmetric dipped beam and has a higher level and Lower level extending edge portion (19 or 8). At the on lower level edge portion (6) adjoins the area, which for generating the broader light portion of the asymmetric Light serves.
  • the first panel (4) is pivotable about an axis (10), which parallel to the optical axis of the reflector (1) and by a lateral Area of the fixed aperture (3) passes.
  • a fixed to the fixed panel electrical actuator (12) arranged below the first aperture.
  • the electrical actuator is via a plunger (20) with the first panel coupled.
  • the first panel is in an active position, in which serves its diaphragm edge for generating the asymmetrical light, and in an inactive position, in which their diaphragm edge below the Aperture edge (9) of the fixed aperture (3) is arranged, adjustable.
  • a second adjustable aperture (5) is between the fixed aperture (3) and the first panel (4) arranged.
  • the second panel (5) is rod-shaped and in the Cross-section rectangular.
  • the second diaphragm (5) also exists like the other two panels (3, 4), made of sheet metal.
  • the second aperture (5) is at an axle (11) pivotally mounted on the fixed panel (3).
  • the Axis (11) is adjacent to the axis (10) and passes through the outer edge the fixed panel (3) through.
  • the axis (11) is through a Swivel bearing and a locking device (13) formed.
  • the locking device (13) is accessible by hand and allows the second aperture (5) in an active and to pivot inactive position. In the inactive position, the second runs Aperture below the aperture (9) for high beam while in the active Position at a distance above the diaphragm edge (9) for high beam passes.
  • the second diaphragm (5) and the first diaphragm (4) produce together in the active position a diaphragm edge (7) for generating a symmetrical Low beam.
  • the active second diaphragm (5) is in High beam.
