摘要

Flexible conduit 5 which is extensible and retractable and can be used for connecting two openings, one of which has the role of capturing light and the other of which has the role of diffusing light. This conduit comprises a flexible sheath 6, having a smooth wall, made of a material capable of deforming elastically both in the longitudinal direction of the sheath and transversely. Application to the production of a system for natural lighting of a room of a building, comprising a light-capturing element 1 in the roof 2 of the building and a light-diffusing element 3 mounted in the ceiling 4 of the room to be lit, the said flements 1, 3 being connected via the flexible conduit 5 which is mounted in a tensioned state so that its wall remains taut and smooth.
