Abstract
A headlight arrangement for vehicles, particularly for power vehicles, comprises a light source with a light reflector forming a light beam which illuminates a roadway with a predetermined light distribution, and at least one adjustable element for changing the light distribution.
Claims12
A headlight arrangement for vehicles, particularly for power vehicles, comprising a light source with a light reflector forming a light beam which illuminates a roadway with a predetermined light distribution;
- means for sensing a traffic situation forwardly of a vehicle and including at least one sensor with a receiving optical element;
- means for comparing the sensed traffic situation with at least one predetermined parameter and thereby forming a signal;
- and an element for changing the light distribution, controlled by said signal.
A headlight arrangement for vehicles, particularly for power vehicles, comprising a light source with a light reflector forming a light beam which illuminates a roadway with a predetermined light distribution;
- at least one adjustable element for changing the light distribution;
- means for sensing a traffic situation forwardly of a vehicle;
- means for comparing the sensed traffic situation with at least one predetermined parameter and thereby forming a signal which controls said element for changing the light distribution, said means for comparing and forming being formed as an electronic computer connected with said means for sensing and said element for changing the light distribution.
