ILLUMINATED SIGN-BOARD Russian patent published in 2006 - IPC G09F13/00 

FIELD: advertising technologies, in particular, engineering of sign-boards, with use of color-effect illumination and decorative principle.

SUBSTANCE: illuminated sign-board consists of elements of image, consisting of letters or any graphic images, each of which contains light-impenetrable substrate held on support by brackets. On frontal surface of substrate along contour of each element of generated image closed edging is made, which can be made either light-impenetrable or light-penetrable. In edging light-penetrable external cover is held, which can be made light-dissipating. In space between frontal surface of substrate, edging and light-penetrable external cover light-emitting sources are positioned, for example, point radiation sources, such as light diodes or laser diodes. On back side of substrate, along its contour light-impenetrable edging is positioned. In space formed by back surface of substrate and light-impenetrable edging light-emitting sources are positioned, wave length of optical emission of which is different from optical emission wave length of light-emitting sources, positioned at frontal surface of substrate, at least, near its contour. Behind formed image light-reflective screen is positioned.

EFFECT: amplified illumination of image, its contrast level, possible generation of largely varying multi-color and dynamically changing images.
