Artificial lighting device for e.g. sauna, has light source installed in casing outside of room, and light conduction system conducting light into room through duct opening, where system is designed as light conduction tubes

摘要

The device has a light source (07) installed in a casing (02) outside of a room (01), and a light conduction system (03) conducts a light into the room through a duct opening (04). The system (03) is designed as light conduction tubes (14) made up of a translucent material, where the tubes include light conduction medium and light reflection medium. The duct opening is mounted at a wall surface (12) of the room using the insulator.
