JPH0961746A - Pipe for transporting sunbeam into room - Google Patents

Abstract

PROBLEM TO BE SOLVED: To easily guide the sunbeams to a place where the sunbeams do not arrive by an ordinary method and to obtain illumination, sterilization and thermal effects, etc., by forming a mirror for reflecting the sunbeams on the inside surface of a hollow pipe, thereby forming a sunbeam transporting pipe. SOLUTION: The light increased in the sunbeam density by a device 6 for condensing and following up the sunbeams is admitted from a conical pipe 4 through a sunbeam inlet into the sunbeam transporting pipe 3 and is introduced to a sunbeam outlet 3 while the light is reflected successively at the mirror on the inside surface of the sunbeam transporting pipe 3. The light is then released from this outlet. The sunbeams are condensed and the powerful light having the high density is introduced into the sunbeam transporting pipe 3, by which the light quantity released by reaching the sunbeam outlet is compensated. The sunbeam transporting pipe 3 is capable of transporting the sunbeams of the intensity appropriate for practicable use. The sunbeam components are separated and diffused at every reflection on the mirror but all of the sunbeam components eventually reach the sunbeam outlet and are released because of the in-pipe sepn. and diffusion in the sunbeam transporting pipe 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to easily deliver sunlight to a place where sunlight cannot reach by a usual method.

[0002]

2. Description of the Related Art Techniques for delivering sunlight using mirrors and prisms are well known.

[0003]

Problems to be Solved by the Invention This has the following drawbacks. 1) When sunlight is collected and dense light is reflected by a mirror or prism, the condensed light has an angle of focusing, so the dense sunlight that is reflected and condensed at the angle of focusing It is difficult to deliver. 2) Sunlight has the property of separating and dispersing, and when carried over a long distance, the sunlight will disperse, making it weaker,
Unless it's a short distance, you can't deliver sunlight suitable for practical use. 3) When attaching a mirror or prism, it is necessary to accurately match the reflection angle and optical axis and fix it on a table that does not cause distortion. 4) Separation and distribution is difficult from the middle of the solar path. 5) A device that accurately follows the sunlight is required. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

1) Build a mirror (2) that reflects sunlight by attaching a mirror plate to the inner surface of a hollow pipe (1) of concrete, metal, plastic, etc., polishing, painting, laminating, etc., and use it as a solar transportation pipe (3). . 2) One of the sunlight carrying pipes (3) is used as a sunlight inlet (7) and the other is used as a sunlight outlet (8). At the entrance of sunlight, a trumpet tube (4) having a mirror on its inner surface is attached so that light can be condensed to some extent even if an error occurs in the tracking accuracy of the device (6) that collects and tracks sunlight. 3) When the sunlight emitted from the sunlight outlet (8) separates its components and shows a rainbow color, a frosted glass-like component for re-mixing and emitting the separated sunlight components to the sunlight outlet (8). Install the sunlight component mixing plate (5). 4) The air in the sunlight carrying pipe (3) expands and contracts due to the stoppage of heat generation due to the influence of sunlight, so the air filter (9) for entering and exiting the pipe is connected to the sunlight inlet (7).・ Install at the solar exit (8). The present invention is a solar carrier having the above-mentioned configuration.

[0005]

[Function] The light whose sunlight density is increased by the device (6) for concentrating and following the sunlight enters the solar carrier pipe (3) from the trumpet tube (4) through the sunlight inlet (7), While being reflected by the mirror on the inner surface of the light-carrying pipe (3), it is guided to the sunlight outlet (8) and emitted.

[0006]

[Effects of the Invention] Although the sunlight is attenuated every time it is reflected by the mirror (2) due to the mirror efficiency, it is possible to collect the sunlight and introduce strong and dense light into the sunlight transport pipe (3). The amount of light that reaches the sunlight outlet (8) and is emitted is compensated, and the sunlight transport pipe (3) is capable of transporting sunlight having a strength suitable for practical use. Also, the sunlight components are separated and dispersed each time they are reflected by the mirror (2), but due to the separation and dispersion within the pipe of the sunlight transport pipe (3), as a result, all of the sunlight components are emitted from the sunlight outlet (8). And is released. When the sunlight from the sunlight outlet (8) part separates and shows a rainbow color, the sunlight component mixing plate (5) is attached and emitted in order to remix the sunlight components. Further, the trumpet tube (4) can be installed without the sunlight concentrating / following device (6) if the trumpet tube itself can condense sunlight and captures and transports sunlight for a limited time. can do. In addition, if a suitable solar filter / automatic diaphragm mechanism (10) is installed in front of the solar light concentrating and tracking device (6), a comfortable solar light component and light amount can be taken in.
Moreover, since the sunlight is reflected at random in the pipe, it can be easily branched and distributed from the middle of the pipe.

[0007]

[Effect] According to the present invention, sunlight can be easily transported to a place where sunlight does not reach, and in the daytime, it is possible to provide a substitute for electric lighting, a sterilizing effect by ultraviolet rays, a heat effect by infrared rays, and the like.
It can be used as an energy saving device during the day.
