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 core 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. The resulting adhesive elements are relatively densely distributed toward a downstream direction and thinly distributed upstream, or the adhering area of the elements is selected to be smaller upstream and larger downstream.
