Title: Optical fiber illumination device
Inventor: TOKUDA SHUICHIRO
IPC: F21V8/00
Filed: 1993-03-31
Abstract: PURPOSE:To maintain the transmission performance of an optical fiber without deterioration of properties by the light and heat from a light source by heat treating a bundled incident end by heating in an atmosphere above the softening temp. of optical fibers and below the melting temp. thereof, thereby obviating the generation of spacings between the optical fibers and assuring the efficient incidence of the light from the light source. CONSTITUTION:The incident end 2 of the optical fiber bundle 1 of a light guide is tentatively bundled and this bundled end 2 is heat treated by heating in the atmosphere above the softening temp. of optical fibers and below the melting temp. thereof. The outer peripheral parts of the optical fibers are softened by this heat treatment and the softened optical fibers flow into the spacings between the optical fibers to fill the spacings. Consequently, the optical fibers come into tight contact with each other and thereafter, the molten fibers are fusion solidified by cooling. The optical fiber parts to be deformed by softening are only the outer peripheral parts of the optical fibers and since a core-sheath structure to exhibit light transmittability is maintained, the light transmission performance of the optical fibers is retained without being impaired even if the light is made incident from the light source facing the incident end 2.
