Flexible system for hanging and illuminating pictures on walls, uses same wires for suspension and for supplying low voltage d.c. power to spotlight

摘要

Pictures are suspended from a horizontal contact rail, which is screened by a decorative clip-in trim . The support wires between the rail connectors and the frame of the picture also carry a low voltage d.c. current. The current is fed via metal support rods to the filament of the spotlight above the picture.
