ABSTRACT:
A sign frame having a rigid structure, the frame of which contains a mounting collar attached to a heat pipe extending vertically from the center of the lower horizontal member of the sign frame. An integrated solar heating means within the luminaire of the sign, and a means for timing the release of the stored heat to the fluorescent bulbs is provided. The internal illumination means for the sign includes a flexible vinyl sign face stretched over a the sign cabinet's rigid frame over, in which the flexible vinyl sign face material has sewn hems on all edges with inserted rigid rods and tension springs extended through the hems and hooked to the rods. The invention also provides a control method for determining the run time for loads utilizing solar power.
