ABSTRACT:
A first support arm section is hingedly connected to a second support arm section to form therewith a light source support arm which can be selectively articulated into either an extended or a folded over disposition. A first end of the support arm is formed for connection to a lamp support post and base; while a second end of the support arm is formed to support a light source such as a bulb socket and a lamp shade. The first support arm section and second support arm section are each formed of tubular stock to facilitate electrical wiring and a spring has its ends connected to adjacent hinged portions of the first and second support arm sections to surround hide and protect the electrical wiring and to bias the first and second support arm sections towards each other. In the extended disposition the support arm sections are coaxially aligned and carry a light source so that the illumination is directed downwardly. In the folded over disposition the support arm sections are aligned and parallel to each other and support the light source so that the illumination is directed upwardly. The effects of gravity are sufficient to keep the support arm in either disposition.
