く、そのま＼光エネルギーとして利用することである。At the time of JIL, we entered an era of global energy, and research and development is being actively conducted in various fields on the effective use of solar energy. It is to use energy directly as light energy without converting it into other forms of energy such as thermal energy or electrical energy.

てきた。From this point of view, at 1'f-1), the present applicant introduced sunlight into the 1F N14 cable using a lens, etc., and installed the light guide kefle in the 1st section to create any desired structure. He has already made a divine proposal in 1988-19 to emit light from a light conductor cable and provide it with illumination.

ある。Therefore, when trying to use solar energy for lighting as described above, the light propagating inside the optical conductor cable has directionality, so it is necessary to cut the end of the optical conductor cable. Is that the amputation? When light is emitted from point S, the radiation angle θ is usually 46 degrees, which is quite narrow, and when trying to uniformly illuminate a room by using sunlight to illuminate the room, etc. However, if the end of the optical conductor cable is simply cut and light is emitted from the cut point, satisfactory illumination cannot be achieved. Therefore, the present applicant has proposed various optical radiators that can effectively diffuse the light propagated within the optical conductor cable and uniformly illuminate a wide area. The present invention was made as part of this effort, and basically, a light scattering material is sputtered in a spiral shape on the surface of a light guide, and the light introduced into the light guide is transmitted to the outside of the light guide through the light scattering part. It is designed to emit light.

質で形成されている。The figure is an enlarged side sectional view for explaining one embodiment of the optical radiator according to the present invention. In the figure, 1 is a light guide, and 2 is a light scattering material sputtered spirally on the surface of the light guide 1. , the light scattering body is made of a material with a refractive index greater than the refractive index of the light guide 1.

囲でしか放出されない。Therefore, the light introduced into the light guide 1 is effectively radiated out of the light guide through the light scatterer portion 2 and is used for illumination or other purposes. In addition, in this case, the pitch P of the spiral structure 2
By shortening sequentially along the direction of light propagation, it is possible to emit a circle approximately evenly from the entire light guide 1, and it is also possible to provide a reflector 3 or the like on the end surface of the light guide. When the light guide 1 is kept, the light reflected by the reflector 3 and returned within the light guide 1 can also be radiated in the radial direction of the light guide 1.)
Y, the light introduced into the conductor 1 can be effectively radiated to the outside of the light guide. It is also possible to use the light guide 1 sealed in a transparent or translucent container 4 as shown in the figure, which prevents the light guide 10 from coming into contact with other objects and being damaged. This also prevents dust or hand marks from forming on the surface of the light guide, and also prevents water stains from accumulating on the surface when used in water, for example when used as a light source for culturing chlorella. It can be kept clean at all times, and since it is first released into the water through an air layer inside a sealed container, it has the effect of scattering light in a desired range and direction. If the sealed container 75 were to have no lid, light would be emitted only in a very narrow range from the tip of the light guide cable when used underwater.
以上の説明から明らかなように、本発明によると、簡単
