The Design for Casting Internal Illumination System of Optical Guide Fibre Beams

This article summarizes a novel design for casting internal illumination system of optical fibre beams. The system illustrated in the article includes photocircuit principles,key points of the design as well as focus-moving features of the ring-like lens which ought to be taken into account. In additon,ways to raise the efficiency of the illumination transmission are also stated in the following three aspects: photoimpact,distributed branch fibre beams and optimum optical fibre beams.
