Abstract
The present invention is a display light box comprising several compartments with partitioning walls shaped according to a translucent image on a frontal display panel. The compartments are illuminated by LEDs, which are installed a distance away from the picture panel to accomplish uniformity of the light on the panel, and driven by a controller so the LEDs may be turned on and off in any pre-determined sequence, accomplishing a changing presentation and thereby making the light box more attractive. The intensity of each compartment may be designed to be different, by the number of LEDs installed in the compartment or by the number of LEDs turned on at any given moment. In addition, LEDs in the same compartment may be turned on and off in certain pattern, accomplishing additional artistic impression.
