FIELD: lighting. ^ SUBSTANCE: invention relates to lighting equipment and can be used in the field of advertising information, architecture and design. Device consists of two distantly placed light guiding elements, at least one solid element and point light source. Wide surfaces of light guiding elements are coated with diffusively reflecting and/or diffusively translucent marks. Solid element is surfaced with character graphic marks. Solid and light guiding elements are arranged in space with inline and angular offset, and they form jointly three-dimensional configuration. There is photo-optical communication between solid element and at least one light guiding element. Point light sources cohere optically with end surfaces of light guiding elements and are electrically connected with electronic program-control unit. ^ EFFECT: increasing device information capacity, ensuring even illumination of optical elements and realising new optical effects of displaying character graphic information. ^ 12 cl, 23 dwg |
