Optical transmission tube, method for making it and linear illuminant system |
摘要 |
In an optical transmission tube (1) comprising a tubular cladding (11) and a core (12) within the cladding having a higher index of refraction than the cladding, a strip-shaped reflecting layer (13) is longitudinally extended between the cladding and the core. Light passing through the core is reflected and scattered by the reflecting layer to emerge from the tube through an area of the outer surface of the cladding opposed to the reflecting layer. The optical transmission tube is prepared by dispersing scattering particles in a monomer solution; filling a tubular cladding with the monomer solution; resting the cladding horizontally for allowing the scattering particles to settle on a lower inner surface of the cladding; and thereafter, causing the monomer solution to polymerize and solidify within the cladding. <IMAGE> |
