Abstract

PURPOSE:To increase the quantity of light flux to be introduced to an optional position of a construction and in proportion to the quantity of a wall body by providing a device for collecting sunlight, a wall body having a light transmitting passage for introducing this sunlight, and a device for diffusing the introduced light flux from the wall surface. CONSTITUTION:The light flux of a collected sunlight is introduced by a hollow part 7 to an interior wall below, and diffused as an emitted light 11 into a room by a diffusing device having a diffusion mirror 8. It can be situated above an opening part 10 which is too close to an adjacent construction 12 to be sufficiently lighted to use as an auxiliary light. The efficiency of the introduced light can be improved by inserting a pipe or material having a mirror surface into the inner surface of the wall body hollow part or coating the inner surface itself with mirror surface.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a solar entry wall system.

[Prior Art] Conventionally, devices that condense sunlight, introduce its luminous flux, and diffuse it for use include systems known as optical ducts, etc., in which optical transmission paths are specially provided within a structure; 6 However, the cost of the entire daylighting system is low in terms of the light duct method, which requires a large amount of space within a limited structure, and the use of expensive optical fibers over long distances. The disadvantage was that it became large.

[Problems to be Solved by the Invention] Conventional solar light introducing wall systems have the above-mentioned configuration, and thus have had the problem of always providing special equipment within the structure. The present invention utilizes the hollow part of a noncombustible plate-like body having a hollow part, which is normally used for the wall of a structure, as an optical transmission path, and does not require a particular area for the optical transmission path. It is possible to continuously introduce sunlight as long as the wall surface is continuous, and by installing a diffuser at any position on the wall surface of the room, it is possible to introduce sunlight continuously at any position on the structure and on the wall surface. It is an object of the present invention to provide a solar light introduction wall system that can increase the amount of light flux introduced in proportion to the amount of light introduced.

[Means for Solving the Problems] ■ The present invention has been made to solve the above-mentioned problems, and includes a device for concentrating sunlight and an optical transmission line for introducing the concentrated sunlight. The present invention provides a sunlight introduction wall system characterized by comprising a wall body having a wall body and a device that diffuses the introduced light flux from the wall surface.

(2) Hereinafter, the embodiments of the present invention will be explained.

FIG. 1 is a sectional view of the basic configuration of the present invention, and FIG. 2 is a sketch. 1 is the parallel rays of sunlight, 2.3 is the reflecting mirror of the condensing device, and 4 is a short duct that introduces light into the hollow part of the wall.At the same time, it is designed to prevent rainwater from entering the hollow part of the wall. A cover may also be provided to cover the entire condensing device described in 2.3.4. Reference numeral 6 denotes a wall body made of a noncombustible material and having a hollow portion 7, which is generally called an extruded cement board. The concentrated sunlight beam is guided into the hollow part 7, reaches the lower indoor wall, and is diffused into the room as emitted light 11 by the diffuser 9, which has a diffuser mirror 8. . It can also be used as an auxiliary light by positioning it above an opening in an IO where 12 adjacent structures are close to each other and insufficient light can be taken in. Furthermore, it is desirable to increase the light guide efficiency by inserting a pipe or material having a mirror surface into the inner surface of the hollow wall portion, or by coating the inner surface itself with a mirror surface.

[Function] In the present invention, the light condensing device is not necessarily limited to a method that combines reflecting mirrors, but also a method that tracks the reflecting mirror according to the altitude and direction of the sun, or a method that focuses light with a lens or the like to increase the density of the luminous flux. A method of guiding light may also be considered. Although the condensing device is not specified in this manner, it is desirable that the condensing device work to efficiently introduce light into the hollow portions of the light transmission sections arranged in a row.

Furthermore, since the interior of the optical transmission path is expected to reach high temperatures, the walls must be made of a nonflammable material. In addition, in order to minimize transmission loss due to reflection, refraction, etc., it is desirable to increase light guide efficiency by inserting a pipe or material with a mirror surface into the inner surface of the hollow part, or by coating the inner surface itself with a mirror surface. .

There is also no particular restriction on the device that diffuses the light beam guided from above into the room through a diffuser mirror, a diffuser plate, etc., to an arbitrary position in the room where the light is to be diffused. There are no particular restrictions on the device as long as it can generate diffused light that can be used as illumination.

[Example 1 The fourth example is a case where the device according to the present invention is installed in a building.
As shown in the figure. Normally, in urban areas, buildings are often constructed adjacent to each other, and in such cases, the sun often does not shine through the openings provided in the surfaces throughout the day. A light condensing device is installed on the roof of the relevant side of such a building,
By constructing the wall according to the present invention, it becomes possible to guide light by making the wall continuous, regardless of its position or distance, even in rooms where the sun does not shine during the day.

Furthermore, since it is constructed from an extruded cement board with a hollow section that can be constructed using common construction methods at low cost, it can be constructed by any craftsman who specializes in wall construction.

[Effects of the Invention] The present invention makes it possible to easily construct an optical duct using the thickness of the wall by a known construction method such as extruded cement board, and to connect it continuously in the vertical direction. In order to increase the amount of light condensed, adjustment can be made by increasing the length of the wall in the width direction. In addition, by generally constructing extruded cement boards in areas other than the optical transfer path to be introduced, there are no particular restrictions on the interior or exterior design. Furthermore, since it is an extruded cement board made of non-combustible material, it is effective in preventing fires from occurring due to temperature rise inside the optical transmission line or heat generated by light focused by a lens or the like.

In addition, since extruded cement boards are commonly used for exterior renovation work, it is also possible to add a cladding with a light-collecting system to the outside of an existing building, eliminating darkness between buildings. It becomes possible to introduce sunlight into any room.
