PROBLEM TO BE SOLVED: To provide a modular, highly efficient optical fiber illumination system which is easily repaired and replaced.SOLUTION: A modular optical-fiber-based illumination system comprises: a light source (52); a low-scatter light-conducting optical fiber (54) optically coupled to the light source (52) and having an output end (58); and a light-diffusing optical fiber (12) having a glass core, a cladding layer and a plurality of nano-sized structures situated within the core or at a core-cladding layer boundary. An input end (62) of the light-diffusing optical fiber (12) is removably and optically coupled to the output end (58) of the low-scatter light-conducting optical fiber (54). Various light sources (52), including UV, infrared, colored, and white, may be used. With a UV source (52), the light-diffusing optical fiber (12) may desirably have one or more phosphors for converting UV into one or more other wavelengths, and the illumination system may include a filter or absorber that prevents or reduces propagation of the one or more other wavelengths. |
