Abstract
The projection headlight has a reflector (10), a light source (20) arranged in a peak region of the reflector, a stop or mask (30) arranged in front of the reflector and a projection lens (40) arranged in front of the stop or mask. The reflector (10) and the light source (20) are pivotally mounted and connected with each other so as to rotate together about a rotation axis (60) arranged in the vicinity of a second principal point of the projection lens (40). The illumination device has at least two of these projection headlights, advantageously on opposite sides of the vehicle. The angular orientations of the reflectors (10) are controlled independently of each other in the illumination device.
Claims15
A projection headlight for a vehicle, said projection headlight comprising a reflector (10) having a peak region (P), a light source (20) mounted in the reflector (10) in said peak region of the reflector, at least one stop or mask (30) arranged in front of the reflector and a projection lens (40) arranged in front of the at least one stop or mask;
- wherein the reflector (10) and the light source (20) are pivotally mounted and connected with each other so as to rotate together about a rotation axis (60) and said rotation axis (60) is arranged in the vicinity of a second principal point of the projection lens (40).
An illumination device for a vehicle, said illumination device comprising at least two projection headlights, wherein each of said at least two projection headlights comprises a reflector (10) having a peak region (P), a light source (20) arranged in the peak region of the reflector, at least one stop or mask (30) arranged in front of the reflector and a projection lens (40) arranged in front of the stop or mask, the reflector (10) and the light source (20) being pivotally mounted and connected with each other so as to rotate together about a rotation axis (60) and said rotation axis (60) being arranged in the vicinity of a second principal point of the projection lens (40);
- and
- means (C,M) for controlled rotation of said reflectors of said at least two headlights independently of each other, whereby light beams from said projection headlights are propagated in respective directions independently of each other.
