LIGHTING DEVICE BASED ON LIGHT GUIDE WITH LIGHT-SCATTERING PARTICLES AND LIGHT ANGLE SELECTION MODULE Russian patent published in 2017 - IPC F21V8/00 

Abstract RU 2638822 C2

FIELD: lighting.

SUBSTANCE: lighting device (1) comprises a light guide (2) with introduced light-scattering and/or light-reflecting particles (5), the first light-emitting element (6a) and the second light-emitting element (6b). The lighting device is designed in such a way that for the light rays emitted by the first light-emitting element (6a), the incidence angles of the light rays introduced into the light guide (2) are within the first angular interval, and in such a way that for the light rays emitted by the second light-emitting element (6b), the incidence angles of the light rays introduced into the light guide (2) are within the second angular interval. The first angular interval and the second angular interval are different.

EFFECT: ensuring uniform lighting.
