ILLUMINATION DEVICE, SURFACE LIGHT SOURCE AND LED DISPLAY Russian patent published in 2013 - IPC F21S2/00 F21S4/00 G02F1/13357 

FIELD: electrical engineering.

SUBSTANCE: each fist reflector plate (3) is designed so that to cover the corresponding light guide conduit (5) surface that is the surface opposite to the output light emitting surface (5c) of the corresponding light guide conduit (5). Each second reflector plate (4) is arranged on the surface of the corresponding first reflector plate (3) that is opposed to the surface turned towards the corresponding light guide conduit (5) over the corresponding first gap (1), each first gap (1) formed by two overlapping neighbouring light guide conduits. Each second reflector plate (4) covers the area where the first reflector plate (3) is not in place in the corresponding first gap (1) and passes over two neighbouring light guide conduits (5).

EFFECT: small thickness and improved uniformity of the light emitting surface luminescence brightness; creation of a surface illumination light source including such illumination device; creation of a LED display including the surface illumination light source as a backlighting source, ensuring high image quality and having small thickness.
