FIELD: lighting.
SUBSTANCE: invention relates to the field of lighting and in particular to devices of daylight. Collector (3) collects daylight fluorescent light (4), which is held the light guide (5) to the position to be light, along the optical path, and the light is absorbed by the fiber. Photoluminescent material (71, 72) is located within the optical path, and emits a photoluminescent light which compensates for the absorption of fluorescent light guide.
EFFECT: technical result is to increase efficiency to compensate for losses from the absorption of daylight.
