摘要:
A light radiator for use in the cultivation of fish is described. The device includes a light guide for introducing light rays therein through its end portion and emits the same through its peripheral surface, a first-transparent container for hermetically accommodating therein the light guide and a second semitransparent container for hermetically accommodating therein the first transparent container. The second container is placed in water so as to outwardly project the light through the semi-transparent container.

A light radiator has a tubular body bearing at the center of one end a removable light-emitting end of a fiber optic cable and having at the other end a large number of light-guiding rods arranged tightly and parallel to each other. The light-guiding portion includes two groups of light-guiding rods, the first group consisting of rods having their light-emitting end-surfaces on the same plane and the second group consisting of rods having their end-surfaces on a plane lower than that of the first group's rods. Each light-guiding rod of the first group and each light-guiding rod of the second group are in contact with each other at least on one side and each light-guiding rod of the second group has a tapered, concave-shaped output end.

A light radiator is described which is capable of being threadably attached to the light-emitting end of a fiber optic cable to radiate light rays transmitted therethrough. The light-guide rod has a thread at a circumference of its one end in order to be threadably connected to the light-emitting end of the fiber optic cable and the light-guide rod has a spiral groove at its circumference. The spiral groove gradually getting deeper as it approaches the rod's tip in order to diffusively radiate the light therefrom.

A solar ray-collecting device comprising a Fresnel lens, an optical coupling made of a tip-cut conical light guide and an optic cable is described. The solar rays focused by the lens are received at the large end of the optical coupling and discharged from the small end of the optical coupling and further guided into the optic cable. The Fresnel lens has a numerical aperture smaller than that of the optic cable. The optical coupling has the light-emitting end with the numerical aperture equal to that of the optic cable so as to eliminate the reflection loss. The light-emitting end of the optical coupling being adhesively joined to the light-receiving end of the optic cable by the use of an optical paste.

A light rays radiation device for administering oral medical treatment to a person's gums that has a light ray radiating tool attachably and removably connected with the light ray emitting end-portion of an optical conductor cable through which the light rays corresponding to the visible light ray components of solar rays are transmitted to the light ray radiation tool. The light ray radiation tool has a mouthpiece having a transparent curved surface corresponding to the shape of the gums and a large number of optical fibers imbedded in the mouthpiece. The large number of optical fibers are constructed in such a manner that the end portions thereof are placed over the entire area of the transparent curved surface so as to be opposite the gum area and the other-side portions thereof are capable of being connected with the light ray emitting end portion of the optical conductor cable.

A lens-holding apparatus used for holding a hexagonal lens and for fixing the light receiving end of an optical conductor at the focal point of the lens includes a frame body having a hexagonal portion on at least a part thereof, a hexagonal lens tightly inserted into the hexagonal portion, and an optical conductor cable fixing mechanism for fixing the light-receiving end of the optical conductor at the focal point of the lens on another portion of the frame body. The hexagonal portion comprises six side surfaces, every other one of which has two slits formed symmetrically in relation to the center line of each side surface in the longitudinal direction for mounting the lens thereon and a tongue piece formed between both slits. The lens is tightly inserted into the hexagonal portion and held therein by means of a tongue piece for pressing the lens.

A solar ray energy radiation device for use in medical treatment, comprises a transparent or semi-transparent cylindrical member, a cover member for closing off one end surface of the cylindrical member, a covering cap member put on another end of the cylindrical member so as to be removed from and attached to the same, and an optical conductor cable having a light ray emitting end mounted on the cover member. Solar ray energy transmitted through the optical conductor cable is radiated from the light ray emitting end thereof into the cylindrical member and further radiated onto a medical treatment area by bringing the covering cap member into contact with the medical treatment area.
摘要:
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.

A bed employed for use in light bathing. The bed comprises a transparent cloth stretched thereon and optical conductors arranged on the underside of the cloth. The optical conductors are arranged in such a manner that the light rays transmitted therethrough are radiated outside of the optical conductors and pass through the transparent cloth.

Lighting by the sunlight is available in every space in a building, even those spaces which have been hardly utilized such as the basement and ground water pit. The sunlight is collected and guided by optical cables to light radiators which are located in intended spaces of a building. The basement has a cistern for water therein to afford a shelter in the case of emergency, while the ground water pit which is also lighted by the conducted sunshine is usable to cultivate fish, plants, and other foodstuffs. The building is annular except for its first floor so that a cylindrical open space is defined thereinside and also lighted by the sunlight, thereby introducing the sunlight even into the radially innermost spaces of the sunlight.
