Abstract (en)
The present invention relates to a combined solar and artificial lighting system, wherein a sunlight collector is positioned on the exterior of a building and is used to collect sunlight and transfer this into a transferral means for providing the light into the interior of a building. At the interior of the building a plurality of combined solar and artificial light luminaries are located and are adapted such that they provide the daylight collected into the building interior. Additionally, the combined luminaires are possessed of artificial lighting means which can be used to augment the natural daylight passing through the system.
