METHOD AND DEVICE FOR SCRATCHING SURFACE OF OPTICAL FIBER SUBSTRATE AND METHOD OF MANUFACTURING OPTICAL FIBER LIGHTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a device and a method for scratching a surface of an optical fiber substrate by forming a specific illuminating pattern by applying a sand blast to one or more side surfaces of the board while moving the optical fiber substrate by passing through one or more sand blast nozzles.;SOLUTION: The nozzles 4 can be intermittently operated for forming an intermittent light emitting area along the length of the substrate 1. Instead of this, a specific certification pattern may be formed by moving the substrate 1 at a variable speed by passing through the nozzles 4 or adjusting pressure of the nozzles 4 or an interval of the nozzles 4 from a surface of the substrate while moving the substrate 1 by passing through the nozzles 4. A specific illumination pattern can be formed by arranging a porous plate between the nozzles 4 and the substrate 1. After sand blast operation, the substrate 1 is cleaned, and is cut in the desired length, and can be permanently thermoformed so as to become some desired shape.;COPYRIGHT: (C)2002,JPO
