LIGHTING DEVICE AND METHOD OF LIGHTING DEVICE PRODUCTION Russian patent published in 2017 - IPC F21K99/00 F21Y101/00 F21W121/00 F21Y113/20 

Abstract RU 2614135 C2

FIELD: lighting.

SUBSTANCE: invention relates to lighting engineering, namely in a lighting device and a method of making the said lighting device. Lighting device (1) comprises first light-emitting element (101) connected optically with light guide (110) having output surface (111) for lighting by the light guide. Besides, the lighting device comprises second light-emitting element (102) intended for direct lighting by means of the lighting device. First light-emitting element (101), light guide (110) and second light-emitting element (102) are enveloped with shell (130). When an input signal comes to the lighting device, light intensity of second light-emitting element (102) is adjusted relative to light intensity of first light-emitting element (101).

EFFECT: technical result is higher energy efficiency at use.
