Sunlight, fibres and liquid optics: the UFO project

The Universal Fibre Optics project which is part funded by the EC 'ENERGIE' programme involves design and construction of a luminaire which allows the integration of daylight and artificial light. Sunlight is captured through a heliostat and brought into the building by means of a liquid fibre optic cable. Remote artificial backup light is added to maintain the flux output of the luminaire at night and when the sun is obstructed by clouds.
