Abstract
A system for adjusting the direction of a light beam from a headlamp assembly comprises a condenser lens which is movable along an arcuate path. As a vehicle turns a corner, the system moves the condenser lens along the arcuate path, so as to direct the light beam in the direction that the vehicle is moving. Because the condenser lens follows an arcuate path, the light beam is not distorted, allowing for greater angular displacement of the light beam.
Claims17
A headlamp for projecting light in a forward direction, said headlamp comprising:
- a reflector having a reflector axis, a first focal point located along said reflector axis, and a forward-facing reflector opening;
- a light source located proximate to the first focal point;
- a condenser lens disposed forward of the reflector opening, the condenser lens being movable in an arcuate path;
- and
- means for moving the condenser lens in an arcuate path.

A method of steering the beam of light projected by a headlamp, the method comprising the steps of:
- providing a headlamp for projecting light in a forward direction, the headlamp having a reflector with a reflector axis, a first focal point located along said reflector axis, and a forward-facing reflector opening;
- providing a light source located proximate to the first focal point;
- providing a condenser lens disposed forward of the reflector opening;
- the condenser lens being movable in an arcuate path;
- providing means for moving the condenser lens in an arcuate path;
- and
- moving the condenser lens along the arcuate path the condenser lens moves along the substantially horizontal plane.
