Abstract
An electrically conductive ball joint and lighting fixtures using the joint are disclosed. The joint has a ball with a first portion connected to a first electrical signal and a second portion connected to a second electrical signal. The first and second portions are electrically isolated from one another by a nonconductive bushing. A socket receives the ball and has a first set of electrical contacts adapted to make contact with the first portion of the ball and a second set of electrical contacts adapted to make contact with the second portion of the ball. The two portions of the ball are unequal, with one portion being larger than the other. The lighting fixtures generally comprise a base and two or more arms connected to the base. The arms are connected to one another electrically and structurally with the electrically conductive ball joints, and may be counterweighted.
