々のＪｈ８案をしてきた。When using solar energy, convert the light energy into other Jtz such as thermal energy or electrical energy.
It is clear that the most efficient way to use the light energy is to use it as light energy without converting it into energy flj, without any conversion loss. A person standing at such a straw point, focusing sunlight using a lens etc. into the integrated optical cable, and passing it through the optical fiber cable to the desired location ( ri '1M L, -1
At this point, the light is emitted from the guide cable.
(I have made several proposals regarding the use of solar energy and energy for other purposes.) When attempting to use solar energy for lighting as described above, the inside of the conductor cable must be used for U! The incoming light has directionality, and if the end of the optical conductor cable is cut and the light is emitted from the cut, the emission angle will be approximately 46° in the case of focused light. , it is quite narrow, and if you want to use thick light to illuminate the room uniformly, cut the end of the optical conductor cable as shown in 4, If the source is emitted from the cutting tube, it is not possible to perform a satisfactory 1! Many Jh8 proposals have been made for a light radiator that can uniformly illuminate a wide area by spreading the incoming light in a budding manner.

に形成するようにしてもよい。11th'? l is an example of the optical radiator proposed earlier by 'Nf2'! 11, in the figure, ■ is a rod-shaped light guide, 21122-0-21 is a light emitting part provided on the peripheral wall surface of the guide l, 8 is a light guide cable, 4 is a reflecting mirror, A lens for focusing sunlight or artificial light is provided at an end (not shown) of the optical conductor cable 8, and the light focused by the lens is introduced. Therefore, the light focused by the lens is transmitted into the light guide 1 through the optical MH cable 3,
The light propagates inside the guide body 1 in the direction of the arrow without being reflected by the peripheral wall surface of the guide body, and in that direction, the light that hits the part where the light emission section is provided passes through the light emission section. Released to the outside. As shown in FIG. 2 l

Alternatively, it is possible to form a vortex by carving it on the outer circumferential surface of the soC, and the method of its formation is as shown in the figure. The light emitting part may be formed in an annular shape, or the light emitting part may be formed in a circular shape.
History d is multiν<11. - One light emitting section may be formed at random.

光成分を４１効に利用することができなかった。In the case of a double optical radiator, among the light components that are incorporated into the light guide 1 from the light guide 1 cable 8, the light component that is close to parallel to the light guide 1 is transmitted through the light guide 1. The light is not reflected by the surrounding wall, and even if it is reflected, the number of times it is reflected is very small, so there is a very low possibility that the light will hit the light emitting part, and the light reflected by the reflective mirror will also be reflected by the light guide l. Since the reflected light is substantially parallel to the light guide 1, there is a very small possibility that the reflected light will also hit the light emitting portion, and therefore, the light component that is substantially parallel to the light guide 1 cannot be effectively utilized.

Alternatively, as shown in FIG. 4, the reflecting mirror 4 may be
1, so that when the light component propagating in the light guide 1 substantially parallel to the light guide 1 is reflected by the reflection mirror 4, it is made to be as far as possible not parallel to the light component, and the light component is reflected by the light reflection mirror 4. The light propagates in the direction of arrow B (and hits as much light as possible on the light emitting part when cutting).

In addition, it is also possible to form the central part of the reflecting mirror shown in FIG. The emission efficiency of the light component reaching 111 can be further improved.
