Abstract

(57) [Abstract] [Purpose] To absorb a large amount of light at low cost by absorbing and concentrating sunlight from various angles due to the position change of the sun without using an expensive large lens or azimuth correcting device. [Structure] A reflecting agent 7 such as silver or aluminum 11 in the form of fine powder is mixed and formed in optical glass or quartz glass 6, and all surfaces except one end in the longitudinal direction are a reflecting mirror 10 or a magic mirror-like reflecting film. The outer side of 8 is covered with black optical glass or quartz glass 9 and one end portion in the longitudinal direction, which is a light emission port, which is not mirror-finished is bundled, and the lens 2 is attached and introduced into the optical fiber 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light collecting material that absorbs and collects light.

[0002]

2. Description of the Related Art In a conventional condensing device, a small lens or a Fresnel lens is used and introduced into an optical fiber or the like (see, for example, Japanese Patent Publication No. 3-42642).

[0003]

The conventional light concentrating device basically has a configuration as shown in FIG. 3, and the focal length and focal angle of the lens are changed by the change of the sun position with time and season. Since it changes, the distance for accurately guiding it into the optical fiber
There has been a problem that a high cost and space are required for the orientation correction device and the large lens.

Explaining with reference to the configuration diagram, FIG. 3 is an appropriate position between the focal length of the lens and the position of the optical fiber, and FIG. 4 is a position where the lens 2 and the optical fiber 3 are fixed, and the incident distance in summer due to the change of the sun distance. Letting the ray 1 be a, the lens 2 brings the focal point 5 of a'on the optical axis 4 and the incident ray 1 in winter is b, and the focal point 5 is at the position b '. FIG. 5 shows the focal position in the morning and evening, where c is the incident ray 1 in the morning, and c is the focal point 5 of c ′ on the optical axis 4 by the lens 2 and d is the incident ray 1 in the evening. The focal point 5 is attached to the position "', and the light is not applied to the light receiving surface of the optical fiber 3.

Since the present invention has a structure for absorbing and condensing light, it does not require an azimuth correcting device because it absorbs and condenses incident light rays from various angles regardless of changes in the sun position due to time or season. Instead, it aims to provide a large amount of light at a low price.

[0006]

In order to achieve the above object, in the present invention, the light is not collected by an azimuth correcting device and a lens or the like and sent to the optical fiber. A light-collecting material that absorbs and collects light by diffusing light on the outside of a thin film that has two surfaces mirror-coated with silver on the other side and wrapping it in black optical glass or quartz glass to make it a magic mirror Since the entire surface of is a light receiving surface and sends out light only at one end in the longitudinal direction which is not mirror-finished, an azimuth correcting device is not required.

[0007]

[Function] The light condensing material that absorbs and condenses the above light is a light receiving surface, so the length can be changed or multiple light condensing materials can be formed into a plate shape to easily supply a large amount of light. Made it possible. The present invention will be described below with reference to examples and the like.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, an incident light ray 1 passes through a black optical glass or quartz glass 9 and a reflecting film 8 and is diffusely reflected by a reflector 7 inside the optical glass or quartz glass 6. Further, since the reflection film 8 is mirror-shaped from the inside by the black optical glass or quartz glass 9, light is not escaped and is sent out only in the longitudinal direction.

Further, in FIG. 2, a lens 2 is formed by forming a plurality of light collecting materials of the present invention for absorbing and collecting light into a plate shape.
By attaching the, a huge amount of light energy is condensed,
It has made it possible to feed finer optical fibers.

According to the present invention having the above-described structure, it is possible to supply the same amount of light as that collected by a lens having a length of 5 m and a width of 1 m and a diameter of about 250 cm. Just by mounting on the outer wall, it is possible to continue supplying a huge amount of light energy within the sunshine time, and by attaching a lens that bundles one end that is not a mirror surface, which is a light emitting port, the light emitting port emits a small amount. It is a condensing material that absorbs and condenses light, which enables an enormous amount of light.

[Brief description of drawings]

FIG. 1 is a partial vertical cross-sectional view of a single body of the present invention.

FIG. 2 is an oblique projection view when the present invention is formed into a plurality of plate shapes.

FIG. 3 is a cross-sectional view of a lens type light condensing device at an appropriate focus position.

FIG. 4 shows a focus position of a lens type light collecting device in winter.

FIG. 5 shows the focal position of the lens type light collecting device in the morning and evening.
