- the second diaphragm device 30 or 130 independently of the first aperture device 20 or 120 be changed between their first and second states can, so that even if the first aperture device 20 or 120 is in its first state and the Generated light-dark boundary, the second aperture device 30 or 130 is in its second state and thus that beam of light emerging from the headlight Has a light-dark boundary, but higher maximum Illuminance.
- the second aperture device 30 several parts or the second Aperture device 130 has a plurality of areas 135 movable independently of one another or between her translucent and opaque condition are switchable, so as to selectively shield partially to allow light reflected by the reflector 10.
- At least one of the Aperture devices 20, 30 and 120, 130 not only between is changeable in two states but continuously or in can be changed at different levels between different states are the part of the light reflected by the reflector 10, that of the aperture devices 20.30 and 120.130 is shielded to vary.
- the illuminance on your own Traffic side and oncoming traffic side in can be varied in different ways.
- the extent of that emitted by the headlight Beams of illuminated areas 82 and 92 of the measuring screen 80 are changed between a concentration and one wide extension.
- It can also be a one-sided wide Expansion can be set, preferably when cornering and in the direction of the lane.
- a wide one Expansion is particularly bad when cornering Visually beneficial during a concentration in particular is advantageous at high speed. It can also be provided by the headlight in the first Position of the aperture devices 20.30 and 120.130 Fog light bundle with continuous horizontal Chiaroscuro limit and large spread is emitted.
