Abstract (en)
[origin: WO9939134A1] An optical fiber illumination system comprises a segmented reflector that efficiently couples energy from a lamp into a plurality of optical fibers. The segmented reflector offers the ability to improve the coupling efficiency by utilizing the cross-sectional area and numerical aperture of more than one optical fiber at the output of a reflector. Also this reduces the energy collected by a single fiber, and can be useful in preventing damage created by the source intensity. In practice, a source lamp (12) is placed along a reflector axis (16). The reflector (14) is specifically designed for a particular style and type of lamp, and is designed to collect as many rays from that lamp as possible.
