Abstract:
1. A lamp comprising: a lamp housing having a lamp front surface, having inner surfaces defining a substantially round opening, and said inner surfaces defining said opening including at least one surface for rotatively holding a lens, said lamp housing also having a rear outer surface surrounding said round opening and including a first portion on a first side of said lens, a second portion on a second side of said lens, opposite said lens from said first portion, and said second portion being substantially the same area and shape as said first portion, a third portion on a third side of said lens adjacent to said first portion and said third portion being substantially the same area and shape as said first portion, and a fourth portion on a fourth side of said lens adjacent to said first portion and opposite to said third portion, said fourth portion having a different area than any of said first, second or third portions, and being non-symmetrical relative to any of said first, second and/or third portions, said fourth portion defining a mounting surface on an opposite side of said lamp housing to said front surface, said mounting surface adjacent said opening, but offset therefrom in an area which is off center and asymmetrical on the lamp housing relative to an axis defined between said first and second portions; a lens rotating motor, mounted on said nonsymmetrical mounting surface, and connected to operate in a way that allows rotating said lens, said lens rotating motor having a portion that extends outside said lamp housing, on an opposite side of said lamp housing, and said lens rotating motor facing in a direction opposite to a direction of light projection; a reflector assembly, located adjacent said front surface, in a location to shine light through an area of said opening; a back assembly, coupled to a rear surface of said reflector assembly, and including a light socket that is operative to hold a light bulb in a location within said reflector, said back assembly extending by an amount that is effective to counterbalance at least a portion of an imbalance caused by the off center mounting of said lens rotating motor; and a yoke, coupled to said lamp housing, and operative to move said lamp housing in substantially pan and tilt directions.
