ABSTRACT:
An articulating dental operatory light having an electrically powered light source and a mounting assembly with at least a ball and socket joint, and optionally an additional joint, for multi-axial and multi-directional positioning and adjusting of the lamp head assembly, and a rotational stop for preventing damage to electrical wires passing through the joints. The rotational stop comprises a keyed shaft containing the electrical wires, that cooperates with the ball portion of the joint, and a first stop member connected to a remote end of the keyed shaft that interferes with a second stop member, thereby preventing a full 360 degree rotation of the ball portion relative to the socket member of the joint and minimizing twisting damage to the electrical wires.
