してきた。Conventional Technology Recently, we have entered an era of energy conservation, and research and development on the effective use of solar energy is being actively conducted in various fields.However, in order to use solar energy most effectively,
It is to use sunlight energy as it is 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 an arbitrary desired location through the guide cable, and created a light guide at that location. Various proposals have been made regarding emitting light from cables for use in lighting.

Therefore, in order to effectively propagate this algae, it is necessary to provide the algae with an appropriate amount of light energy and an appropriate amount of carbon dioxide gas, but in general, as algae proliferate and their density increases, the algae itself The light is blocked by the shadow.

ている。FIG. 3 is an enlarged side sectional view for explaining an example of a light radiator suitable for application to a chlorella culture apparatus previously proposed by the present applicant. In the figure, 1 is a light guide, and 1a is the light guide. Light introduced into the light guide 1 is reflected by the groove 1a and is effectively radiated out of the light guide. Note that by gradually decreasing the pitch P of the spiral grooves 1a along the direction of light propagation, light can be emitted approximately evenly from the entire optical waveguide 1.
Furthermore, by providing a reflector plate 1b or the like on the end face of the light guide 1, the light reflected by the reflector plate 1b and returning into the light guide 1 can also be radiated in the radial direction of the light guide 1. The light introduced into the conductor 1 can be effectively radiated outside the light guide. The light guide 1 is sealed in a transparent container 2 to prevent the surface of the light guide 1 from being damaged by coming into contact with other substances, and to prevent limescale from forming on the surface when used as a light source underwater. The surface is always kept clean, and the transparent container increases the light emitting area and enables more uniform light emission.

の透過光は緑色光を呈しているので集魚に適している。Figure 1 is a cross-sectional view for explaining an embodiment of the optical radiator for fish farming according to the present invention. It is a functional light guide, and one end of the light guide 1 is either the light guide as it is or a reflector plate 1b is attached, and the other end is connected to a light source and is closely or glued to the light guide cable 11 that propagates light energy. It is fixed by the tool 12. Light is introduced into the guide cable 11 from an end (not shown) of the optical conductor cable 11, but the light has a wavelength suitable for growing algae, and small fish etc. are grown using the algae as feed. For rearing, it is effective to use light with a wavelength preferred by small fish to make it easier to attract fish to the algae. Looking at how fish react to light, when illuminated with sunlight, fish can be broadly divided into fish that like the light and come to it, fish that hate the light and run away, and fish that do not react to light. However, in general, people tend to get scared and run away from blue light, and are indifferent or attracted to red light. When this happens, many fish become frightened and run away, and when illuminated with xenon lamps that emit a lot of ultraviolet light, many fish run away. However, they tend to gather when exposed to green light, and when illuminated with a red helium laser, some fish showed interest and came closer, but many did not react. As mentioned above, fish prefer green light, and since the light transmitted through algae exhibits green light, it is suitable for attracting fish.

魚と養魚を効果的に行うことができる。Reference numeral 2 denotes a transparent cylindrical body that accommodates the light guide 1- as an axis, and is fixed to a mounting bracket 13 in which the light guide 1 is kept coaxial with a stopper @15.15 and the connector 12 is inserted in a liquid-tight manner. The mounting bracket 13 has a flange 13a, and the flange 13
The transparent cylindrical body 2 and the optical conductor 1 are fixed to the substrate 3 in a fluid-tight manner via a packing 16 with bolts 14 so as to pass through a through hole 3a opened in the substrate 3 at point a. Reference numeral 4 denotes a semi-transparent cylindrical body which is fixed to the substrate 3 coaxially with the light guide 1 and surrounding the transparent cylindrical body 2. A light guide 1 is provided on the outer periphery of the substrate 3.
A fixed leg 6 is disposed facing away from the fixed leg, and an anchor 7 is attached to the end of the fixed leg so that the light guide 1 is stably installed on the bottom of the water so that light can be emitted into the water. As described above, in the optical radiator of the present invention, the light guide 1 is sealed on the substrate 3-l2 with a transparent container 2, the container 2 is surrounded by a semi-transparent container 4, and the inside of the semi-transparent container 4 is made hollow. (If water gets in during installation, you can blow air from the bottom with an air hose) to soften the light emitted from the translucent container 4, This makes it easy for algae 18 to grow in the area. Therefore, the outer surface of the translucent container 4 becomes an environment suitable for the growth of algae 18,
Algae 18 grows on the outer surface, and fish gather in search of the green light that passes through the algae, and eat the algae attached to the outer peripheral surface of the translucent container 2 as feed. In this way, translucent container 4
The algae that grows on the outer surface of the tube is eaten by fish, so the initial effect can be maintained without the amount of transmitted light decreasing due to overgrowth of algae. In other words, when algae grows, they eat it, which increases the amount of transmitted light, and fish gather in search of this transmitted light, so there are always fish around the light radiator, making fish collection and fish farming effective. be able to.
