摘要： This display board consists of the transparent acrylic plastic plates in which surface desired letters or pictures are grooved, and a panel made by fitting together a number of the bricks of transparent acrylic plastic. The light receiving edges of the plate, and the light receiving edge and the light emerging edge of the brick are sandpapered in order to make lights enter and emerge from the edge to maximum extent. The light receiving edges of the plates and bricks are colored with a desired to produce a colored light. When light-bulbs with refractors properly positioned at the light receiving edges of the plate and the brick are turned on, the colored lights withthe same color of the dye coloured the edges will emerge from the grooves cut in the plate and from the emerging edge of the brick. For uniform illuminant intensity of the grooves cut in the plate, the depths of grooves are adjusted to be deeper around the center of the plate than around its periphery. An illumination controller is used to control the sequence, interval and duration of an illumination for the most colorful illuminant commercial display. This display board has wide applications for use as a larger scale outdoor signboard, interior decoration, and tail-light of a car.
