| Outline of Final Research Achievements |
A new lighting technology, central lighting system (CLS), was proposed and practically performed in this study. The CLS is based on a solid state excitation light source and a phosphor based visible light distributer. The excitation light is functionally coupled with the light distributer via an optical transmission system by using optical fibers. Because the excitation source is centrally managed and efficiently cooled, it could be operated at any place of far away from the light distributer. Moreover, the light distributer is free of electric wirings and heat loads, and has no influence to characteristics of the light distributer. Accordingly, the CLS could accommodate with various shapes and environments. The proposed CLS potentially contributes to renovate the basic concept of the existing illumination system, and imparts high designability with a simple system.
