Title:
昼光照明装置
Document Type and Number:
Japanese Patent JP5894991
Kind Code:
B2
Abstract:
The invention relates to a daylight illumination apparatus. A daylight collector (3) collects daylight (4), which is guided to an illumination location to be illuminated along an optical path by a light guide (5), wherein the daylight is absorbed by the light guide. A photoluminescent material (6, 8) is arranged within the optical path and emits photoluminescent light that compensates for the absorption of the daylight by the light guide. Absorption losses of the daylight can therefore effectively be compensated, without necessarily needing, for example, an active compensation light source. This allows providing compensated daylight illumination in a technically relatively simple way.
