Abstract
Abstract An optical radiator for diffusingly radiating sunlight emitted from an optical-conductor cable for the purpose of illumination. In order to illuminate a sufficiently wide region surrounding the optical-conductor cable, a cladding layer of the optical-conductor cable located in the region to be illuminated is excised, and the outer surface of the thus exposed of the optical-conductor cable is topically covered by a fine grain adhesive with a refractive index equal to or greater than that of said core.

Claim 1
Independent Claim
94 words
An optical radiator for diffusingly radiating sunlight emitted from an optical-conductor cable for the purpose of illumination, said optical-conductor cable comprising a core made of optical fiber and a cladding layer covering the outer surface of said core, characterized in that at least one end portion of said cladding layer located in the region to be illuminated is excised and that the outer surface of the thus exposed core of the optical-conductor cable is topically covered with a fine grain adhesive with a refractive index equal to or greater than that of said core.
Claim 2
Dependent Claim
94 words
An optical radiator for diffusingly radiating sunlight emitted from an optical-conductor cable for the purpose of illumination, said optical-conductor cable comprising a core made of optical fiber and a cladding layer covering the outer surface of said core, characterized in that at least one end portion of said cladding layer located in the region to be illuminated is excised and that the outer surface of the thus exposed core of the optical-conductor cable is topically covered with a fine grain adhesive with a refractive index equal to or greater than that of said core.
Claim 3
Dependent Claim
97 words
An optical radiator for diffusingly radiating sunlight emitted from an optical-conductor cable for the purpose of illumination, said optical-conductor cable comprising a core made of optical fiber and a cladding layer covering the outer surface of said core, characterized in that at least one end portion of said cladding layer located in the region to be illuminated is excised and that the outer surface of the thus exposed core of the optical conductor cable is topically covered with light-scattering elements adhered with an adhesive with a refractive index equal to or greater than that of said core.
Claim 4
Dependent Claim
97 words
An optical radiator for diffusingly radiating sunlight emitted from an optical-conductor cable for the purpose of illumination, said optical-conductor cable comprising a core made of optical fiber and a cladding layer covering the outer surface of said core, characterized in that at least one end portion of said cladding layer located in the region to be illuminated is excised and that the outer surface of the thus exposed core of the optical conductor cable is topically covered with light-scattering elements adhered with an adhesive with a refractive index equal to or greater than that of said core.
Claim 5
Dependent Claim
125 words
An optical radiator for diffusingly radiating sunlight emitted from an optical-conductor cable for the purpose of illumination, said optical-conductor cable comprising a core made of optical fiber and a cladding layer covering the outer surface of said core, characterized in that at least one end portion of said cladding layer located in the region to be illuminated is excised, that the outer surface of the thus exposed core of the optical conductor cable is topically covered with a fine grain adhesive or light-scattering elements adhered with an adhesive, the refractive index of said adhesives being equal to or greater than that of said core; and that said thus exposed core of the optical-conductor cable is hermetically sealed in a transparent or semitransparent hollow cylindrical capsule.
