Patent ID: 7052165

Claim:
A vehicle headlight assembly comprising: a concave reflector having a focal axis and a focal point on said axis; a light source located on said focal axis, said reflector having an opening aligned with said focal axis; said light source having a tubular conduit extending through said opening on the focal axis; an electrical power means comprising: an electric motor, a pinion gear driven by said motor, and, a rack having a first side fixedly connected to said conduit, said rack having a plurality of teeth for operable engagement with said pinion gear, said teeth orientated on a line that is acutely angled relative to the axis of said conduit, for movement of the tubular conduit in both horizontal and vertical directions; said electrical power means for moving said conduit on its axis through tho plane of said opening, whereby said light source is moved toward or away from the reflector through an infinite number of positions between the high beam and the low beam positions; and, a pivot support means for said reflector, whereby the focal axis of the reflector is adjusted from a generally horizontal orientation to a downwardly-tilted orientation in response to the vertical movement of said conduit as the electrical power means displaces the tubular conduit of the light source from the high beam position to the low beam position.
