ABSTRACT:
A lamp assembly (12, 12A) has a lamp housing (14) and a lens (16) cooperatively forming an enclosure within which an electric light bulb (78) is disposed to place a focal point (82) of the bulb at the focus of a parabolic reflector surface (56) of a reflector (52) that is also disposed within the enclosure. The reflector collects light from the bulb and reflects it as a beam through the lens. A socket (76) that holds the bulb mounts in a rear wall (24) of the enclosure, and the reflector has a through-aperture (74) through which the bulb passes. A positioning mechanism (84) selectively positions the reflector about an axis (61) perpendicularly intersecting the bulb axis (26) to aim the light beam. As the reflector is being positioned, the bulb remains stationary, and the focus of the parabola remains at the focal point of the bulb.
