  • high beam shows a light distribution accordingly curve HD3 in FIG. 9. From FIG. 9 it can be seen that a not insignificant Part of the light distribution is already above the HH horizon, which on the one hand leads to a very good visibility, but on the other hand also to a strong glare of oncoming traffic leads, which are greatly reduced by using the motorway light described can.

  • a medium beam distribution pattern also be designed so that the glare on oncoming traffic on a federal road is kept as low as possible.
  • the main and most effective use of a medium Beam distribution pattern is undoubtedly given when used as a motorway light, since here usually a much higher driving speed than on a federal road prevails and thus in oncoming traffic, the low beam is switched on as it is Federal roads happen, too little illumination of the road brings with it.

This way and This ensures that there is a smooth, continuous transition between the individual beam distribution patterns is possible without the transition between two Beam distribution patterns cause unwanted interference.

  • the scanning lug 10 of the diaphragm 6 still engages circular area of the cam 14, the aperture 6 thus experiences at the beginning of the rotary movement the shaft 16 still no vertical movement. This ensures that not short term undesirable when transitioning from one beam distribution pattern to another Interfering effects, such as the high beam lighting up during the transition from low-beam to low-beam Autobahn light, occur. Only when the aperture 7 has reached its uppermost position gradually begins the downward movement of the diaphragm 6 to a lower position.
  • the height adjustment of the panels can also be done automatically, depending on one Vehicle speed. This makes it necessary to adapt the road illumination possible at the current vehicle speed. Research has shown that the driver's attention especially to those on the light-dark boundary Area of the roadway is directed. It can therefore be useful when driving on a motorway be when the range of the illumination is automatic at a lower speed is reduced, for example, to the driver's attention to that area to steer the vehicle, which is approximately that at the prevailing speed necessary braking distance for stopping in front of an obstacle.
  • the adjustment of the Aperture takes place via electronics known to the person skilled in the art, which are the motor controls according to the vehicle speed and the respective aperture in that position moves, which generates a light distribution corresponding to the speed.

  • To turn the two cams 14, 15 is a only motor 17 is provided, thereby reducing the manufacturing cost of the invention Headlights can be kept low compared to other headlights.
  • Another advantageous aspect is that switching between different Beam distribution patterns are essentially silent. This can be attributed to this that the transition between the different aperture positions takes place continuously and the shutters are held in the desired position via the cams become. With other headlights with an adjustable cover, however, the cover snaps in an end position or is moved against a stop, which is often characterized by a unpleasant click noticeable.
  • the mode of operation of the invention also extends to three or more Apertures can be used to generate four or more beam distribution patterns can, the cams necessary for height adjustment of the diaphragms in turn on a common shaft can sit and are driven by only one motor. It only has to care must be taken that the cams are shaped accordingly and with regard to their eccentricity are offset from one another so that there is a continuous transition between the individual Beam distribution patterns is possible.
  • each pair of diaphragms or each diaphragm has its own shaft associated cam is driven.
  • the advantage of using multiple shafts is that when switching between two beam distribution patterns, a brief switch-on an undesirable beam distribution pattern - such as when using three or more apertures, which by means of cams that are on a common driven shaft are arranged, is inevitable -, can be avoided.
  • this is one Embodiment is more expensive to manufacture and requires more installation space.
  • the invention can also be used when only one height-adjustable screen is of great advantage because of the use a cam for moving the diaphragms to switch between two beam distribution patterns - As already mentioned above - almost silent and for the vehicle occupants is no longer perceptible acoustically.
