Abstract
An illuminated picture frame is in the shape of an open box provided with two rows of spaced incandescent, small bulbs arranged on opposite sides of a picture attached to the rear wall of the box. The bulbs on each side are positioned in the apex of a reflector of parabolic cross section, the axis of which is directed towards the picture surface. Fixation of each bulb is in longitudinally slotted bushings extending from the reflector's rear side, permitting the adjustment of each bulb filament in the focus of the parabola. Two bare wire conductors are fastened on the rear side of the reflector, and the terminals of each bulb are soldered to these conductors. One or more batteries are located in a housing on the outside of the rear wall and are connected to the conductors by means of switch.
