LIGHT DISTRIBUTION CONTROLLER APPARATUS, LUMINOUS FLOW DENSITY CONTROLLER APPARATUS, AND DIVISION METHOD Description of the invention TECHNICAL FIELD The present invention relates to a technology for introducing sunlight into a building or to a shaded area between buildings, and with a daylight technology for sunlight or artificial light in a greenhouse, a pond for agriculture, farming or the like, and indoors. STATE OF THE ART The conventional introduction of sunlight into a building or a shaded area between buildings, which traces the sun and introduces sunlight through a reflective body has been costly. In a greenhouse, the daylight supply to each culture rack was carried out by distributing the light from a diffusing material with low transmission that diffuses light in all directions, in a natural agricultural pond natural sunlight was used as is is, and in a culture pond the opportunity for the cultivated products to receive sunlight through agitation was measured. Carrying out a daylight supply in each interior part depended on the distribution of light by the incidence of sunlight and lighting. A method of introducing sunlight into a building or a shaded area between buildings by tracking the sun and reflecting sunlight through a reflecting body is extremely expensive, and acquiring a sufficient amount of light with this method does not become attached to reality. In addition, because the distribution of light that diffuses light in all directions in a greenhouse wastes a large amount of available light and causes a lack of sufficient light, this medium is not usually used to increase the efficiency of the light. space of use in a greenhouse, so many greenhouses still suffer from low efficiency in the use of space. Although agitation in a culture pond has an effect of increasing the efficiency of the use of optical energy, the problem that a large amount of light incident with a large angle of incidence with respect to a water surface is not solved it loses by reflection, and that the irradiation of light to a cultivated product is limited to the proximity of the surface of the water. The use of a large amount of lighting as table lamps to provide daylight in each interior part keeps the use of another interior daylight at a low level. DISCLOSURE OF THE INVENTION The present invention was devised to solve the aforementioned problems, and it is an object of the present invention to provide means for irradiating a sufficient amount of light to a shaded area and part prevented from receiving a sufficient amount of light. due to a structure or other objects, by controlling the distribution of light or controlling the luminous flux, by diffusion, refraction, division and the like of light. A light distribution controlling apparatus according to the present invention is an apparatus for, as placed, distributing light to an area or a part that does not receive light by varying the progressive direction of the light using a light source. transparent body to carry out the diffusion, refraction or division, or diffusion and refraction complex of light, and a device controlling the luminous flux density is an apparatus for increasing a number of rays advancing towards a specific area or part which requires a large amount of light, by diverting to the area or the specific part of those rays that go to an area or a part adjacent to the specific area, using the transparent body previously mentioned. Additionally it is possible to realize the distribution of the light with excellent uniformity and little waste by combining a device controlling the distribution of light of this type and a device controlling the luminous flux. The transparent body can be formed from a transparent body on which are arranged multiple protuberances of cross section with an arc shape, an angle shape, a triangle shape and a wavy shape. As the transparent body of this type, a transparent body in the form of a flat plate or in the form of a film having many protuberances formed in parallel to each other on at least one of its surfaces can be used, a transparent body constituted by a beam of monofilaments multiple or bar-shaped bodies, or a transparent body constituted by a textile fabric in which multiple monofilaments or bar-shaped bodies are interwoven. Conventionally, for the distribution of light with a high degree of uniformity over an entire target area that includes an area or a part to which light does not arrive easily, it is possible to achieve the distribution of light to the small parts or the deep parts and a percentage of rays that eventually remain unused can be minimized by guiding by a transparent body to the area or the specific part, the rays progressing to an area or part adjacent to the specific area or part, increasing a density of the flow luminous of the area or the specific part, and effecting diffusion, refraction or division, or a diffusion and refraction complex in the rays using the transparent body. Additionally, in some cases the uniformity of the light distribution can be increased and simultaneously minimized. In addition, the percentage of the rays that are not used will eventually be used through the repetition of a light distribution control of this nature. A division method according to the present invention is a method for bringing a daylight illumination to a space divided by a material for interior partitions insofar as it obstructs the view so that the contour of a person can not be identified. or article through the material of the division, using as a material of the division a transparent body that carries out a diffusion or a diffusion and refraction complex of the incident light on a plate-shaped surface, film form or shape of fabric, to emit light by the other surface, and effecting diffusion or diffusion and refraction complex of incident light on a surface to transmit in a specific direction.

THE BEST WAY TO CARRY OUT THE PRESENT INVENTION The embodiments of the present invention will be described below based on the attached drawings. Mode 1 Fig. 1 shows a light distribution controller according to the embodiment 1 of the present invention. As shown in the figure, the two-story buildings 2 are built adjacent. In this case, as shown in Fig. 1 (A), when the sun's rays 1 impinge from the top left direction, a shaded part 3 of a building and 4 shaded parts occur inside. to the structure of a building. Similarly, as shown in Fig. 1 (B), when the sun's rays 1 impinge from a superior perpendicular direction, shaded portions 4 are produced in the interiors. Accordingly, as shown in Fig. 1 (C), a transparent body 5 is disposed over the two buildings 2. In this case, as shown in Fig. 1 (A) to (D) and Fig. 3 (A) to (I), a transparent body in the form of a flat plate or a film shape in which multiple protuberances having an arc-shaped cross-section, shaped in the form of an arc, can be used as the transparent body 5 of angle or of wavy form. Additionally, as shown in Fig. 4, a transparent body constituted by a textile fabric in which multiple monofilaments or bar-shaped bodies are interwoven can be used. These transparent bodies have diffusion characteristics which are shown, for example, in Fig. 5 (A) and (B). The transparent body 5 is arranged in an orientation in which the protuberances on its surface are substantially parallel to the opposite surfaces of the two buildings 2. As shown in Fig.
1 (C) and (D), the solar rays 1 are diffused by the transparent body 5, and the diffuse light reaches an area or part that was normally shaded. It can be seen that the shaded areas indicated by the hatched portions in Fig. 1 (C) and (D) are considerably reduced compared to the shaded areas of Fig. 1 (A) and (B) where use the transparent body 5 As shown in Fig. 1 (E), the transparent body 5 can be disposed at the level of the higher sides of the two buildings 2. Modality 2 As shown in Fig. 6 (A), if not only the transparent body 5 is disposed over the two buildings 6, but also a transparent body 7 is disposed between both buildings 6, the number of rays that continue towards the interior of the buildings 6 is increased, and the percentage of the rays that are not used eventually can be smaller and, at the same time, the uniformity of the distribution of the light can be increased. In the case that the transparent body 7 has protuberances in the form of a prism as shown in Fig. 7 (B) or (C) and has a diffusion characteristic as shown in Fig. 7 (A), even if the transparent body 7 is arranged horizontally between both buildings 6 as shown in Fig. 6 (B), the multiple rays incident on the transparent body 7 affect the interior of both buildings 2. Modality 3 As shown in Figs. Fig. 8 (A), it is possible to direct multiple rays to the part between the buildings 2 causing the solar rays 1 that illuminate the roofs of both buildings 2 to affect transparent bodies 8 arranged on the buildings 2, and additionally having a body 9 transparent between these two buildings 2, and at the same level of the roofs of the buildings 2 it is possible to direct the rays downwards effecting diffusion, refraction or division, or a complex of diffusion and refraction of the rays of the transparent body 9. According to this method it is possible to direct more rays to the part between both buildings 2 compared to the method in which only a single transparent body 5 is used, as shown in Fig. 1 (C), (D) and (AND). Furthermore, as shown in Fig. 8 (A) and (C), if a transparent body 10 is disposed below the transparent body 9 and between both buildings 2 it is possible to introduce additional rays into the interior. of the buildings 2. As regards the cultivation of plants in a greenhouse, the buildings 2 in the descriptions of each of the previously mentioned modalities can be considered as cultivation shelves or tall plants, and the relation of use of sunlight and the relation of use of space in the greenhouse can be considerably improved. Regarding the application in agriculture, or in a pond for the cultivation of algae or photosynthetic bacteria, by covering the surface of the water with a transparent body it is possible to reduce the reflection on the water surface of the light incident with a large angle with respect to the surface of the water, and it is possible to introduce a greater amount of light to the water. In this case, the direction of the protuberances of the transparent body is preferably adjusted to a position that allows to introduce to the water the largest amount of sunlight according to the place where the transparent body is used. Additionally, the arrangement of a transparent body on the surface of the water allows the rays to be collected in a specific area, and it is possible to supply a greater quantity of light to the products grown below the surface of the water. In this case, if the water surface of the specific area is covered with a transparent body, a ratio of daylight illumination in the water can be increased. It is also possible to increase a ratio of use of sunlight by adding transparent bodies below the surface of the water or by arranging reflector bodies. Mode 4 As shown in Fig. 9 (A) and (B), if a transparent body 12 is disposed in the vicinity of a panel 11 of solar cells, and the solar rays 1 proceeding towards a periphery of the panel 11 of Solar cells are collected by the transparent body 12 on the solar cell panel 11 by diffusion, refraction or division or a diffusion and refraction complex it is possible to increase the power generation of the solar cell. In the same way as in Fig. 9 (A) and (B), through the collection of sunlight and artificial light from the environment it is possible to introduce a greater amount of light towards a specific interior area. Modality 5 Conventionally, because a division that is used indoors is constituted by an opaque body, the division blocks the light from the outside and therefore, lighting equipment is often required to complement the light in a space divided by a division, but by the use of a transparent body 5 as shown in Fig. 2 (A) to (D), Fig. 3 (A) to (I) and Fig. 4 as dividing material, as shown in Fig. 10 it is possible to introduce light into the space inside the division even without specifically using lighting equipment. Specific Example An experiment was conducted by arranging optical fibers of polymer of 0.25 mm in diameter as shown in Fig. 2 (D), and using three types of transparent bodies, specifically a first transparent body fixed to a transparency retention plate of 2 mm thick acrylic resin with a bilaterally adhesive film, a second transparent body consisting of a transparent sheet of approximately 0.16 mm thickness with multiple protuberances having an angular cross-section, manufactured by Dai Nippon Printing Co., Ltd. on a surface, and a third transparent body of approximately 0.5 mm in thickness with multiple protrusions having a triangular cross-section, manufactured by Mitsubishi Rayon Co., Ltd. arranged on a surface. Two models of a building with a contour like the one shown in Fig. 11 were manufactured using 3 mm thick balsa wood material, and the transparent bodies were arranged in the models, and by irradiating sunlight over the buildings visually confirmed the effects of the transparent bodies. As a result of the experiment, the characteristics shown in Fig. 1 (C), (D) and (E) and Fig. 6 (A) were clearly observed in the first transparent body and the second transparent body. Additionally, the characteristic shown in Fig. 6 (B) was clearly observed in the third transparent body. Regarding each transparent body itself, by irradiating red rays from a laser emitter sold on the market it was confirmed that the first and the second transparent body have the characteristic of Fig. 9 (A) and the third transparent body has the characteristic of Fig. 7 (A). As described in the foregoing, according to the present invention it is possible to introduce a sufficient amount of light to a shaded area or part or to have an insufficient amount of light due to a structure or other objects.
