LIGHT-EMITTING SYSTEM FOR EMISSION OF SCATTERED LIGHT Russian patent published in 2016 - IPC F21V8/00 G02B6/00 

FIELD: electricity.

SUBSTANCE: invention is referred to the light-emitting system, which comprises multitude of neighbouring light-emitting devices. Each light-emitting device comprises plate-like light waveguide having the front, rear and end surfaces. The light source is placed near the plate-like light waveguide in such position that scattered light enters the light waveguide and propagates in the main direction parallel to the front surface. The light waveguide comprises three-dimensional surface structure through the front, rear surfaces and one end surface. The controlled light waveguide is controlled against characteristics of output light.

EFFECT: improved uniformity of illumination due to reduced contrast effects as dark lines between bordering surfaces of light waveguides.
