Claim:
1. An articulating clamp assembly for supporting a traffic control device on a support structure, the clamp assembly comprising: a first clamp member having a first end and a second end, an opening in the first end, an opening in the second end, and an internal channel connecting the openings in the first and second ends forming a first conductor path segment therethrough, wherein the first conductor path is substantially straight, the first clamp member having a longitudinal axis, wherein the second end is connectable to the luminaire; a second clamp member having a first end and a second end, an opening in the first end, an opening in the second end, and an internal channel connecting the openings in the first and second ends forming a second conductor path segment therethrough, wherein the second conductor path in the second clamp member is substantially straight, the second clamp member having a longitudinal axis, wherein the second end is connectable to the support structure; wherein the first end of the first clamp member and first end of the second clamp member are connectable to each other to form an articulating joint that connects the first and second conductor path segments to form a concealed conductor path extending through the connected first and second clamp members, wherein the articulating joint permits adjustment of the angle formed by the longitudinal axis of the first clamp member relative to the longitudinal axis of the second clamp member, and wherein the concealed conductor path extending through the connected first and second clamp members is straight when the longitudinal axes of the first and second clamp members are parallel; and wherein the articulating joint comprises a first planar joint face on the first end of the first clamp member and a second planar joint face on the first end of the second clamp member, wherein the first planar joint face defines a first engagement surface and a first plane, wherein the second planar joint face defines a second plane and a second engagement surface that matingly and adjustably engages the first engagement surface on the first planar joint face whereby one of the first and second planar joint faces can be rotated relative to the other of the first and second planar joint faces to adjust the angle formed by the longitudinal axis of the first clamp member relative to the longitudinal axis of the second clamp member, and wherein when the first and second engagement surfaces are matingly engaged the planes defined by the first and second planar joint faces are parallel to each other and to the longitudinal axes of both the first and second clamp members.
