LIGHTING PANEL Russian patent published in 2009 - IPC G09F13/00 F21V8/00 

FIELD: advertising.

SUBSTANCE: panel contains light conducting panel element, light source and point-matrix light-efferent structure. Light conducting panel element is produced from transparent material and has face light-efferent surface. Radiated by light source light rays come to light conducting panel element through its edge. Point-matrix structure is formed on face surface of light panel element. Points of point-matrix structure are distributed on surface unevenly and their area on different parts of surface is not equal. Density of points in places with brighter glow of face surface is lower, in places with less bright glow of face surface is greater. Distribution of points on surface area is determined applying model-analogue of light panel. Distribution is obtained by fixation of picture of luminosity of illuminated by light source of face surface of model, transformation of fixed picture of glowing in raster monochromic picture- point-matrix structure, reproduction of obtained point-matrix structure on face surface of light panel's panel element.

EFFECT: identical glowing throughout the area of illuminated picture.
