Vehicle headlight system with variable beam shape
First Claim
1. A vehicle headlight system comprising:
- a light source (2) having an optical axis (6);
at least one reflector (1) for shaping the light emitted by the light source into a high beam and a low beam (4, 5);
a first shield (7) adjustable via an actuating element (9) between a position in which the light from the light source (2) is blocked across a maximum cross section and an essentially transmissive position in which this light is substantially allowed to pass; and
a second shield (12) displaceable sideways relative to the reflector (1);
wherein the first shield (7) is mounted such that it is pivotable about an axis (8) and is oriented perpendicular to the optical axis (6) independent of its position;
wherein the actuating element (9) is adapted for adjusting the first shield (7) in a plurality of continuous intermediate positions between the maximal blocking and the essentially transmissive position in which the blocked cross section is less than the maximum cross section;
wherein the actuating clement (9) is provided approximately at the height of the lower edge of the reflector (1); and
wherein the first shield (7) is mirrored on its inside facing the reflector (1).

Abstract
In a vehicle headlight system with a light source (2) and at least one reflector (1) for shaping the light emitted by the light source into a high beam and a low beam, and with a shield (7) adjustable via an actuating element (9) between a position in which the light from the light source (2) is blocked across a maximum cross section and an essentially transmissive position in which this light is substantially allowed to pass through, the actuating element (9) adapted for adjusting the shield (7) in a plurality of intermediate positions between the maximal blocking and the essentially transmissive position in which intermediate position the blocked cross section is less than the maximal cross section.

15. A vehicle headlight system comprising:
-
a light source (2); at least one reflector (1) for shaping the light emitted by the light source into a high beam and a law beam (4,5); a first shield (7) adjustable via an actuating element (16) between a position in which the light from the light source (2) is blocked across a maximum cross section and an essentially transmissive position in which this light is substantially allowed to pass; wherein the actuating element (16) is adapted for adjusting the first shield (7) in a plurality of Continuous intermediate positions between the maximal blocking and the essentially transmissive position in which the blocked cross section is less than the maximum cross section; wherein the actuating element is provided approximately at the height of the lower edge of the reflector (1); and wherein the first shield (7) is mounted slidable on a rail (14) and is driven by the actuating element (16) to move along the rail (14).
