Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention introduces sunlight indoors without electrical conversion, and is mainly used in rooms with poor sunlight such as north-facing rooms and basements of ordinary houses. This invention relates to a device for introducing sunlight indoors so that people can bathe in natural light even when they are indoors.

(Conventional technology) Introducing sunlight into living rooms is extremely important for promoting the health of residents and keeping the rooms bright, and various devices have been used for daylighting in various buildings since ancient times. Ta. Typical examples include various windows and skylights installed on the sides of buildings.
In addition, the atrium and courtyard were designed to benefit from sunlight as much as possible in the architectural form, and more recently, sunrooms that extend out onto terraces have also appeared. These devices receive sunlight either directly or indirectly through a translucent plate such as glass, but more recently, solar rays are concentrated with a condensing lens and transmitted through optical fibers. Attempts have also begun to be made to irradiate the light in certain places.

(Problem to be solved by the invention) However, when enjoying the benefits under the direction of sunlight irradiation, such as through a daylight window, skylight, or atrium, the range where the benefits can be enjoyed depends on the angle of incidence of the sunlight, etc. However, although the lighting method using a combination of a condensing lens and optical fiber is effective in solving the above problems, it requires another means of tracking the trajectory of the sun. However, the device required a large amount of force and the installation cost was high, so it was not yet suitable for use in general houses.

Solution to Problem C) The present invention was made in view of the above, and by combining a large number of hemispherical condensing lenses, optical fibers, and diffuser lenses, it can be installed easily and inexpensively, and can be installed facing north. It is an object of the present invention to provide a novel indoor sunlight introducing device that can effectively irradiate natural light even in rooms with poor sunlight such as rooms and basements.

To explain the present invention based on the accompanying drawings, FIG. 1 is a partially cutaway schematic perspective view showing a typical example of the device of the present invention, and FIG.

FIG. 4 is a partially enlarged vertical cross-sectional view of the lined portion, and is a schematic vertical cross-sectional view of a house to which such a device is applied. That is, the gist of the device of the present invention is that a plurality of condensing plates (1-) are formed by arranging a large number of upwardly convex hemispherical lenses 11-. A light transmission line 2 organized by optical fibers 21- guided out from the center of the lower surface and bundled together, and a hemisphere curved convexly downward to which the secondary end of the light transmission line 20 is connected to the center of the upper surface. The light-diffusing unit 3 including the lens 31 .
1-
... and the light scattering unit 3- are connected via the light transmission line 2, the absorbed sunlight rays are transferred to the light transmission line 2.
It is characterized in that it is pressed so that the interior R of the room R is irradiated through the hemispherical lens 31 of the diffuser unit 3.-.

In Figure 4, the above-mentioned condensing plate... is located on a south-facing roof r.
It is placed so that it covers the entire surface of the roof, and has the same function as roofing materials such as tiles. That is, the light condensing play) 1.
- As shown in FIGS. 1 and 2, a large number (50 to 100) of hemispherical lenses 11... are closely arranged, and substantially each hemispherical lens 11... is a part of a certain company. Therefore, the upper surface is an impermeable surface consisting of continuously repeated unevenness, and if these are closely laid on the roof board with adhesive, the roof will be formed. It fully performs its function as a material. The light condensing plate) 1... is integrally molded from glass or synthetic resin such as acrylic, and its maximum thickness C is the distance between the bottom surface and the top of the hemispherical lens 11... radius)
is preferably 20 to 30 m+. The optical fibers 21 constituting the light transmission line 2 are made by bundling ordinary glass fiber optical fibers with their proximal ends connected to the center of the lower surface of each hemispherical lens 11 of the condensing plate. In some cases, this is extended to reach the light scattering unit 3, and in other cases, as shown in FIGS. A matrix-like light guide base 20 that focuses the light is molded from a synthetic resin with excellent translucency such as acrylic resin, and is coated with a mercury vapor deposited film. Main optical fiber 211 coated with mercury vapor deposition film
A coupler 201.

In addition, the light scattering unit 3 includes a hemispherical lens 31 for light scattering inside a shade 30 molded in the same way as a normal lighting fixture, as shown in FIG.
... are installed with their convex curved surfaces facing downward, and the secondary end of the light transmission line 2 is connected to the center of the upper surface of the skeleton hemispherical lens 31.... This hemispherical lens 31-.. is molded from glass or acrylic resin, etc., like the condensing plate 10 and hemispherical lens 11.
As shown in the figure, those molded independently, or those molded with two or three pieces in a row (not shown) are adopted.
The size and number of such hemispherical lenses 31 are appropriately selected depending on the desired illuminance. Such a light scattering unit 3 is used in each room B, which is difficult to be directly irradiated with sunlight, as shown in Fig. 4.
・It is attached to the ceiling, wall, etc.

(Function) In the device constructed in Kuniya H as described above, the condensing plate functions as a roofing material and also functions as a condensing plate.
1... The sunlight S irradiated upward is a hemispherical lens 11.
..., and its center, that is, the optical focus 0
..., and the concentrated light beams are further focused and transmitted to the light scattering units 3 through the optical fibers 21 of the light transmission line 2. Diffusion unit 3
..., the bundle of light introduced into the center of the hemispherical lens 31--, that is, the optical focal point 0', is diffused here and directed into the room R from the downwardly convex curved surface of the hemispherical lens 31-. irradiated. Therefore, you can enjoy the benefits of sunlight even in north-facing rooms, rooms surrounded by walls, basements, etc. where it is difficult for sunlight to enter directly.
In the process of diffused light, ultraviolet rays and heat are absorbed, so natural light that is extremely suitable for human health and plant growth reaches room B.

(Effect) As described 1. In the device of the present invention, the entity that absorbs the light from the condensing plate 1 is the hemispherical lens 11, so no matter what angle the sunlight is irradiated onto the condensing plate 1, the sunlight remains at its focal point O. ...is concentrated on... Therefore, by arranging a large number of hemispherical lenses 11-- in a plane, a large flame beam can be used to track the changes in the angle of incidence of sunlight from morning to evening or from winter to summer. It is possible to effectively condense light without using any equipment.Furthermore, the condensing plate can be manufactured at low cost because it can be heated integrally with glass or synthetic resin. If ・ is made non-water permeable as mentioned above, it will itself function as a roofing material in place of tiles etc. Therefore, if this device is installed at the same time as the Japanese house H is constructed, it will be even more effective. Costs are reduced. The light effectively absorbed by the light condensing play) 1 is transmitted by the light transmission line 2 and irradiated by the light scattering unit 3, so you can enjoy the benefits of sunlight anywhere in the house H. This makes it possible to easily create a ``house full of light'' without using electricity or other forms of energy, which greatly contributes to the improvement of human health and the growth of plants. In view of this, it is clear that the value of the present invention is extremely large.

In the above example, the condensing plate was installed on the roof, but it goes without saying that the same effect can be obtained even if it is installed on a wall with good sunlight.

In addition, when installing on a roof, leaves etc. may accumulate on the irregularities on the plate and reduce its effectiveness, so cover the entire surface of the condensing plate with a transparent plate etc. It is obvious that it can be freely adopted within the design scope.
