スイッチに関する。The applicant first focused sunlight energy using a lens system, etc., introduced it into the temple of light as a thousand lines of light, and spread it to any desired location through the light guide, and used it for illumination and other purposes. We proposed that it be provided to facing the camera, focus the sunlight using a lens system, etc. as described above, and
When transmitting light to a desired location for use, it may be necessary to change the transmission path of the light and use it at a different location. For example, it would be possible to provide sunlight to a bedridden elderly person by guiding the focused light as described above into the room of the bedridden elderly person, but in such a case, it would be possible to temporarily interrupt the sunlight supply. There are times when it is desired to put an elderly person to sleep, and in such a case, the present invention temporarily suspends the supply of sunlight to the elderly person, and also allows the sunlight to be used for other purposes. This invention relates to an optical path changeover switch that can be used and extended in a container or room.

ブル３には、太陽が出ている限り太陽光が尋人される。FIG. 1 is a schematic overall configuration diagram showing one mode of use of the optical path switching switch according to the present invention. In the figure, 1 is a convex lens for focusing sunlight, and 2 is for converting the focused sunlight into parallel light beams. 3 is an input light guide cable into which the parallel light beam is introduced; 4 is an optical path changeover switch disposed in the path of the light guide cable; 5A, 5B, and 5C are integrated output light cables; 6A, 6B, and 6C are sunlight utilization equipment or rooms, and as is well known, the lens system 1.2 and the light receiving end 1i41j of the optical conductor cable 3 are integrally defined, and the lens system is always connected by a device (not shown). It is automatically controlled to face the direction of the sun, so the light conductor cable 3 receives sunlight as long as the sun is out.

鏡は、次のようにして製作することができる。The sunlight that is applied to the light conductor cable 3 in this way is
When the optical path changeover switch 4 is in the small state, the light guide cable 5A goes straight as shown in the figure and is inserted into the light guide cable 5A, and then the light guide cable 5A*:i is turned into the solar light 1J light source. It is supplied to the container or room 6A. Therefore, as mentioned above,
When the solar energy utilization equipment or room 6A does not require sunlight, or when the other solar energy utilization equipment or room 6B or 6C wants to utilize sunlight, in such a case,
When the optical path changeover switch 4 is rotated in the direction of arrow A, the sacrificial light transmitted through the optical conductor cable 3 is reflected by the reflective concave 4' of the optical path changeover switch 4, and is reflected by the output optical conductor cable 5B or &i5C. At the same time, 4 people will supply solar power to solar power equipment 6B or 6C.
The supply of sunlight to the solar equipment or part t'A 6 A can be interrupted if, as mentioned above, it is focused by a lens system and reflects a source of high energy density. , a reflective mirror that is highly heat resistant and does not cause the optical path to change due to thermal expansion, cracks locally due to expansion, or even explode due to sudden changes in polarization is reliable. However, a reflecting mirror that satisfies these costs can be manufactured as follows.

MA? ! In the figure, 4a (is a substrate with excellent thermal conductivity such as isocalic black or lead, and 4b is an oxide film uniformly produced by thermal decomposition of an organic esterified metal).
IA and 4C are evaporation layers made of aluminum or the like, and the oxide thin film 4b is made of an acetic acid ester solution (TiOzllll!) of an organic esterified metal (for example, titanium) on a layer of isotropic graphite made of isotropic graphite. Approx. Heating is carried out at a temperature increase rate of 11 mm, and then the temperature is maintained at a temperature of 11 mm for a predetermined period of time, followed by gradual cooling.Then, the mixture is heated and maintained in a constant temperature of 1 K, and then slowly cooled. The vide thin film produced by thermally decomposing esterified metals has less till'p:s- property than conventional coating thin films, but the surface can be formed uniformly. It is easy to uniformly evaporate aluminum etc. on top of it, and therefore,
It is possible to form a heat wave with excellent reflection efficiency. Further, since the above-mentioned reflective surface is provided on the isotropic 1"l-black M1 having excellent heat and thermal conductivity, there is no risk of thermal expansion, thermal deformation, thermal explosion, etc. It should be noted that it is easy to understand that in order to further improve the hV loss of heat, it is possible to form a heat dissipation surface such as a fin on the forward graphite or attach a heat dissipation base material. Although the embodiment in which the optical path is a light guide cable has been described, the present invention is not limited to light guide cables, and can also be used in cases where the light path is a space. When using a conductor cable, etc., as shown in FIG.
It is preferable to integrate isotropic graphite with excellent thermal properties and heat conductivity to prevent light from leaking to the outside, thereby preventing burns, fires, etc. caused by light in the energy-dense layer. In that case, as shown in the figure, the light guide 8 is integrated with the graphite, and the light guides 2.5A to 5C are connected to the base conductor 8 using couplings 9. good.

利用することが可能となる。As is clear from the above, according to the present invention, the optical path of parallel light with high energy density can be effectively switched, and therefore sunlight bundled by a lens system etc. can be selected into desired pieces. This makes it possible to supply sunlight more effectively and use the sunlight more effectively.
