ABSTRACT:
An illuminated display is disclosed, comprising a housing, a reflector and a light source for displaying translucent photographic images. The reflector and the light source are specially designed relative to each other to provide uniform luminance on a plane containing the image being displayed. An interchangeable frame and an adjustable positioning structure are used to make the display as functionally practical and as aesthetically pleasing as a conventional picture frame.
