Swedish company Parans has found a way to collect sunlight by panels in over 500 lenses, transmit it through fibre-optic cables and illuminate light-deprived interiors. In each room, the sunlight flows out through specially designed luminaires.

Parans’ luminaires give a mixture of parallel light beams and ambient light, just as when the sun strikes through the foliage of a forest. The system allows you to tell the weather even without windows or skylights, re-establishing a connection with the outside environment.
