Fibre illumination system

Source: EP2426402A The invention relates to a fibre illumination module and system for the collection and delivery of daylight for illumination purposes. The fibre illumination module comprises a plurality of collector elements, each collector element comprising an input fibre having a first end and a second end, and a collection optics, the collection optics being configured to receive light incident on a distal end of the collection optics, to transfer at least partially the incident light to a proximal end of the collection optics, and to couple at least partially the transferred light from the proximal end of the collection optics into the first end of the input fibre, each collector element having a principal axis for the collection of light defining an optical axis of the collector element. The optical axes of the collector elements are arranged in a radially outward pointing multi-directional arrangement. The fibre illumination system comprises a fibre illumination module of the above-mentioned type. By the invention, daylight may be exploited for the illumination of remote interior spaces of buildings in order to save energy, and improve the well-being of users in both housing and working environments.
