[Problem that the idea aims to solve]

The conventional configuration described above has the following problems. First, the automatic solar tracking function In order to achieve this effect, a driving part and complicated control are required, and the equipment, especially the light condensing part, is large. The problem was that it became formal and complicated. Also, the equipment is relatively large. Therefore, there was a problem in that the installation location was limited to rooftops and the like.

0004 The present invention was developed based on these points, and its purpose is to In particular, optical transmission equipment that has a simplified and smaller condensing section and can be installed anywhere. Our goal is to provide the following.

[0005]

[Means to solve the problem]

In order to achieve the above object, the optical transmission device devised in this application is a place where sunlight can reach. They can be installed at any location on a building and each is oriented in a specific direction. The light condensed by the multiple concentrators is connected to an optical transmission cable. A condensing connector that condenses light through a cable, and an optical transmission cable from the condensing connector above. The invention is characterized in that it is equipped with a spectrometer that separates the light transmitted through the light beam into multiple light-using parts. It is a sign.

[0006]

[Effect]

Multiple light concentrators are installed in any part of the building where sunlight reaches. It is. These multiple concentrators are fixed in a state where they are each oriented in a predetermined direction. has been done. In other words, rather than following sunlight, each individual concentrator It focuses sunlight in the opposite direction, and as a whole, it collects sunlight without leaking. multiple The light collected by the multiple concentrators is sent to the concentrator connector via the optical transmission cable. The light is focused. The light focused on the condensing connector is sent to the spectrometer via the optical transmission cable. From there, the light is separated and transmitted to multiple locations where the light is used.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to FIG. 1 through FIG. 8. First, buildings 1, and a light condensing section 5 is suspended from a veranda 3 of this building 1. child The light condensing section 5 has a configuration as shown in FIGS. 2 and 3. That is, multiple A condenser 9 is arranged. The above condenser 9 has the Fresnel lens 11 on the front side. It has a structure that allows it to move up, down, left and right.

[0008] The plurality of light condensers 9 are each oriented in a predetermined direction. In other words, thick The direction of incidence of sunlight changes with time, as shown by arrows a, b, and c in Figure 2. I will do it. Therefore, sunlight from the direction shown by arrow a is placed on the left side in Figure 2. Sunlight from the direction indicated by arrow b is collected by an arbitrary number of concentrators 9 as shown in FIG. The light is collected by an arbitrary number of light concentrators 9 shown in the center, and further in the direction shown by arrow c. The sunlight is collected by an arbitrary number of concentrators 9 shown on the right side of FIG. In other words , the individual concentrators 9 have their directivity fixed, but as a whole they leak sunlight. The structure is such that it focuses light without any interference.

[0009] The sunlight collected by the light collector 9 is transmitted through the optical transmission cable 13. The light is focused on the connector 15. That is, a plurality of light collecting connectors 15 are provided. They are arranged so as to correspond to an arbitrary number of condensers 9, one by one. light condensing connector As shown in FIGS. 4 and 5, the casing 15 has a parabolic mirror shape and a half mirror 19 arranged in the housing 17 and an arbitrary number of light input connectors 21 and one light output connector 23.

0010 As shown in FIGS. 2 and 3, the plurality of light collectors 9 and the light collecting connector 15 are It is housed and arranged in the casing 25, and on the front side of this casing 25, A transparent cover 27 is attached. Then, the light focused on the light collecting connector 15 The light is concentrated on the largest condensing connector 15, and from there the light is connected to the optical transmission cable. The light is focused on a spectroscope 31 via a lens 29.

[0011] The spectroscope 31 has a configuration as shown in FIG. First, casing 3 3, and this casing 33 has a built-in mirror 35. Also, one light input connector 37 and a plurality of (two in this embodiment) light output connectors 39, 39. installed. Then, the light entering through the light receiving connector 37 is directed to the mirror 35. Therefore, the light is reflected and separated, and the light is used via the respective light output connectors 39, 39. It is also transmitted to the lighting equipment 41, 43 as a part via optical transmission cables 45, 47. It is.

0012 The lighting fixture 41 functions as direct lighting, and is as shown in FIG. It is configured. First, there is a frame 49, and inside this frame 49 there is a diffusely reflecting mirror surface. A shade 51 is installed. Then, the light that enters through the light input connector 53 is transmitted to the sphere. The illumination is reflected by the surface mirror 55, and is further diffusely reflected by the diffused reflection mirror shade 51. Illuminated as bright light.

[0013] On the other hand, the lighting fixture 43 functions as indirect lighting, and as shown in FIG. It is structured like this. First, there is a casing 57, and inside this casing 57 there is a , reflecting mirrors 59, 61, 63, and a diffused reflection mirror shade 65 are built-in. And light coming in The light entering through the connector 67 is reflected by the reflecting mirror 59, and then the reflected light is It is reflected by the mirrors 61 and 63, and is further diffused by the diffused reflection mirror shade 65. irradiation. Furthermore, on the opposite side of the reflecting mirror 59, various frames 67 are displayed. It is.

[0014] The operation will be explained based on the above configuration. First, sunlight passes through multiple concentrators 9. The light is evenly focused. The light collected by the condenser 9 is transmitted to the optical transmission cable 1 3, the light is focused on the light collecting connector 15 through the light collecting connector 15, which is the largest one. The light is focused on. The light focused on the largest condensing connector 15 is connected to the optical transmission cable. 29 to the spectrometer 31. The light transmitted to the spectrometer 31 is separated there. The light is transmitted to the lighting equipment 41, 43 via the optical transmission cables 45, 47. , where it is used as illumination light.

[0015] According to this embodiment, the following effects can be achieved. First, the light condensing section 5 The configuration has been simplified. That is, the plurality of condensers 9 are each directed in a predetermined direction. A drive unit that is fixed in a oriented state and follows the sunlight as in the past. This is because there is no need for a control section to control it. Therefore, the installation location is also rooftop etc. It is not limited to this, and as in the example, it is possible to hang it on a balcony 3, etc. This greatly expands the freedom of installation location.

[0016] In addition, in the sense that a driving part is not required, even the condensing connector 15 and the spectrometer 31 can be used. The same is true for them, and therefore, they can also provide the desired functions with a small and simple configuration. can be made to perform.

[0017] Note that the present invention is not limited to the above embodiment. For example, the setting of the light condensing section 5 Installation location, number of condensers 9, number of condensing connectors 15, installation location of spectrometer 31, minutes The number of lights etc. are not limited to the one embodiment described above.

[0018]

[Effect of the idea] As detailed above, according to the optical transmission device according to the present invention, a plurality of concentrators can be connected to each other. They should be placed so that they are oriented in a predetermined direction and follow the sunlight as in the past. It is designed to collect sunlight without any leakage without having to be driven by a drive unit. The structure of the device became simpler and smaller. Therefore, the installation location is limited. There is no chance that it will happen.
