Abstract
An optical fiber display apparatus comprises a display panel, and a plurality of optical fibers, one end of each being optically connected to a light source, and the other end thereof being implanted in the panel from one surface side thereof, so that the end face thereof is exposed at the other surface of the panel. A fixing device is used for implanting of the fibers, and includes a sleeve detachably inserted and held in a through hole formed in the panel, and a ferrule detachably inserted in the sleeve from a side of one end thereof and held therein, the other end of each of the fibers being received and fixed in the ferrule. A second ferrule may be detachably inserted in the sleeve from a side of the other end thereof, to be thus suspended from the other surface of the panel. One end of a decorative optical fiber is received and fixed in the second ferrule to be thus suspended from the display panel. Preferably, the decorative fiber comprises a core, and a cladding surrounding the core, a plurality of cone-shaped openings being discretely formed in the surface thereof so that light conducted in the core is allowed to partially leak out of the cone-shaped openings, whereby the d…
