るようにしたものである。Recently, we have entered an era of energy saving, and research and development is actively being conducted in various fields on the effective use of solar energy. i) Utilizing energy as light energy without converting it into other forms of energy such as thermal energy or electrical energy. From this point of view, the present applicant focused sunlight using a lens or the like, introduced it into a light guide cable, transmitted it to any desired location through the light guide cable, and We have already made a divine proposal to emit light from a GeC conductor cable and use it for illumination.Therefore, when trying to use solar energy for illumination as described above, it is necessary to use a light guide. The light that propagates through the cable is directional, and the light that propagates through the optical conductor cable is directional.
When one part is cut and light is emitted from the cut point, the radiation angle is usually about 46° in the case of focused light, which is quite narrow, making it difficult to use sunlight to illuminate a room. When trying to illuminate a room uniformly, it is difficult to achieve satisfactory illumination by simply cutting the loop of the optical conductor cable and emitting light from the cut point. It is not possible. Therefore, the present applicant has made various proposals regarding an optical radiator that can effectively diffuse the light propagated within the optical conductor cable and uniformly illuminate a wide area. The present invention has been made as part of this, and basically includes at least two light guides connected in cascade with respect to the traveling direction of light, and an inclined surface is provided on the surface to be cascaded. The light propagated within the light guide through the inclined surface is diffused and emitted outside the light guide.
