Abstract

PURPOSE:To introduce solar light widely and diffusively in the desired directions in buildings, by providing fine achromatic prism parts which provide the achromatic effect for diffused and colored light. CONSTITUTION:An achromatic prism plate 9 is formed by superposing a prism plate 5 having many inclined prism bodies 5b and an achromatic prism plate 7 having many prism bodies 7b. The plates 5, 7 are of the same shapes and the materials of the plates 5, 7 are so selected that the chromatic aberrations by the plate 5 are negated by the chromatic aberrations of the plate 7. The solar light is changed of directions and is introduced into buildings by abhering the plate 9 to the window 2 of the buildings.

Description

[Detailed Description of the Invention] The present invention (better) allows solar light to be widely diffused and introduced in the desired direction within a building (room, etc.), thereby allowing the interior of the building to be spread over a wide area without using household lights. 1. In residential areas where buildings are close together, sunlight does not shine on the windows of buildings along the cliff, but on an angle! 6. Therefore, as shown in FIG.
When the window glass 2 is irradiated diagonally, this sunlight or L
/ only lights up the area near the window in room 3 of building 1. Room 3
There are bright and dark areas in the room, and the bright areas feel brighter, so I close the windows with curtains, or there is a dark area in room 3 that attracts attention, so I turn on all the lights in the room. 5゜This kind of thing does not make full use of the light produced by nature, and goes against the grain of energy conservation. .

The present invention was made based on the above background, and it is now possible to introduce sunlight into the entire room, whereas in the past, sunlight only brightened the area near the window of the room.

In order to do this, it is necessary to introduce the direction or width of the light from the sunlight TJ (T, t) arriving at the window glass 2 into the window glass 2 as appropriate and convenient. . Therefore, the inventor of the present invention has considered bonding a triangular optical prism 4 to the window glass 2, as shown in FIG.

According to this optical prism 4, sunlight passes through the window 2 in 1.
It is convenient to be able to brighten the interior of the chamber 3 by making the light incident on the entire chamber 3.However, gluing such an optical prism 4 is impractical in terms of cost, shape, and space. It is not suitable for commercialization and mass production.

Therefore, as shown in FIG. 3, the present inventor created a fine inclined surface 5 oriented in one direction using silicone rubber so that sunlight can be diffused and introduced in a desired direction.
A transparent sorted prism plate 5 having on one surface a group of inclined prism bodies 5b having continuous prism elements a was formed, and this prism plate 5 was attached to the surface of a window glass 2.

Then, as shown in Figure 4, the solar radiation is L- as shown by the dotted line.
The light that had only arrived in the direction 1 came into the room 3 as shown by L-2, and the entire room 3 was able to be brightened. In this case, in order to prevent the tatami from being sunburned by the sunlight I, -2, the angle of the inclined surface 5a of the prism plate 5 should be conveniently designed in advance from the perspective of geometrical optics. T
By irradiating in the direction 7-3, there is no need to worry about burning the tatami mats, and at the same time, the interior of the room 3 becomes brighter, which is convenient.

I thought that the purpose of the present invention was achieved in this way, but due to the illumination by sunlight L(]]', -1 is L-2) in the room 3, a color distribution was created in the room 3. The lighting was different from usual, so I felt uneasy.

The present invention has been achieved by solving the technical problem based on this background.

The inventor of the present invention pondered why the phenomenon described in -1- occurs, and thought that the material from which the prism plate 5 was formed may have some influence, so he tried forming the prism plate 5 from plastic and glass. In the case of , , and , it would require a considerable amount of trial production, so we conducted an experiment using a small device under the same conditions in the case of silicone rubber.33 As a result, all three exhibited the same phenomenon as described above. So I decided to go back to my initial idea. That is, since it is unreasonable to provide the optical prism 4, the prism plate 5 having the prism body 5b is formed. Here, we came to the natural conclusion that although the prism body 5b has a finely formed prism body 5b, it still has the same characteristics2.
FIG. 5 shows an enlarged view of the prism body 5b. When the light 6 reaches the inclined surface 5a and exits the prism body 5b, the light 6
is dispersively refracted and below are red, orange, yellow, edge, blue, indigo,
Forming the solar spectrum in violet order6, this was the cause mentioned above. Therefore, the Great Sunlight L-3 in Figure 4
In this case, the light at the bottom had a reddish tinge, and the lighting at the top had a bluish tinge, making them feel uncomfortable.

However, the inventor thought that it would be better to achromatize the combined light using the prism body 5b.

In this case, it is necessary to prevent the sunlight L-3 exiting the prism body 5b from changing direction. Therefore, with reference to FIG. 6 showing an enlarged view of the prism body 5b, the prism body 5b is
The prism body 7b made in exactly the same way as the prism body 5
If placed in the opposite position to b, the dispersed light 6 will be collected again, eliminating chromatic aberration and producing white.Moreover, if two prisms 15b and 7b made in the same way are used,
I remembered that the light 6 does not undergo any change in direction, just as if it had exited a plane-parallel glass. Let's start with Figure 3 (a)
, an achromatic prism body 7 consisting of a group of prism bodies 711 having an inclined surface 7a and made of the same material as the prism plate 5 shown in FIG. I tried making a prototype (Figure 7). still,
Since the prism plate 7 has the same shape as the prism plate 5,
Figure 3(a).

Prism body 7 in the part corresponding to prism plate 5 in (l)
At the same time, we will include the following signs. Now, prism plate 5
(Prism body 5b) forms the solar spectrum and color generation, so for example, if there is positive chromatic aberration,
The other prism plate 7 (prism body 7b) often has negative chromatic aberration. Therefore, as shown in FIG. 6, it is necessary to form the prism plates 5 and 7 with a material that can effectively achieve the present invention by canceling out the positive and negative effects. Therefore, prism plate 5,
These include silicic acid, potassium oxide, sodium oxide, calcium oxide, aluminum oxide, lead hexamonoxide, barium oxide, zinc oxide, boric acid, antimony oxide, and arsenic oxide. ?), and the prism plate 7
These are borosilic crown, barium crown, heavy barium, Clara 7, and light.

A crown glass (including plastic type) such as lint, flint, heavy barium flint, heavy flint, or Kurz flint should be used. Then, the prism plates 5 and 7 form an achromatic prism plate (transmissive refracting plate) 9. .

Therefore, Iri,
As shown in Figure 7, prism plates 5 and 7 may be attached to the surface of the window glass 20. In this case, the window glass 2 and the prism plate 5 may be integrally formed of the same material, and the prism plate 7 may be attached (bonded) to the surface of the prism plate 5 as shown in Figure 7. good. - In the above, since the prism bodies 5b+d are minute, the window glass 2 and the prism plate 5 can be integrally formed.If the prism bodies 7b and 5b are shaped similarly to the prisms L and 5b (Fig. 8), the prism It can be easily joined to the plate 5 and is suitable for mass production.

In addition, as shown in FIG. 9, a prism plate 5 may be attached to the surface of the window glass 2, and a prism plate 7 may be attached to the inner surface of the window glass 2. In the case where the window crows 2-1 and 2-2 are doubled, and a gap 8 is provided between them, as is often seen in recent houses,
The prism plate 5 may be bonded to one of the opposing surfaces of the window glasses 2-1 and 2-2, and the prism plate 7 may be bonded to the other side (FIG. 10). In this case, since the prism plates 5 and 7 are very thin, the strength of the window glass 2-1, 2-2 increases without eliminating the void 8, and the window glass 20 (inner ) However, since the inclined surface 51) and 7b are not formed,
Cleaning 1 of window glass 2-1 and 2-2 becomes convenient. 11th
The figures and FIG. 12 clearly show that the present invention can be fully applied to introduce a thin beam of light into a dark place where it is difficult to introduce sunlight, making it possible to introduce an enlarged area of light. Briefly, explaining FIG. 11, if a large building 11 is installed adjacent to a small building, the sunlight will not enter the small building 1, so the room 3 It gets dark inside. Therefore, a light reflecting surface 10 is installed on the top of the small building 1 to collect sunlight and convert it into a parallel beam.
A light direction system surface 11 tilted so as to irradiate the sunlight TJ onto the achromatic prism plate 9 (achromatic prism plate 9 is provided on the front surface) is placed near the window 2 so as to receive the light beam from the light reflection system surface 10. By irradiating the achromatic prism plate 9 with light from the light direction system surface 11, the interior of the room 3 can be illuminated with suitable illumination light through the entire window 2. Next, with reference to FIG. 12, a light reflection system that directs light downward through a window 2 provided on the roof of the building 1 [10-C1 A light direction system tilted in the basement 3a] When the surface 11 is irradiated with light, the inside of the basement F room a can be brightened with suitable solar illumination light through the achromatic prism plate 9 provided in front of the light direction system surface 11. The above-mentioned light direction system surface 11
The achromatic prism plate 9 and the achromatic prism plate 9 may be integrally formed 17. .

91 Since the present invention has the above configuration, it is possible to introduce sunlight into the entire room and brighten it without color dispersion, whereas in the past, sunlight only brightened the area near the window of the room. That is, bright areas can be expanded without color dispersion. In addition, since the glass in windows and doors may be replaced with the achromatic prism plate of the present invention, the present invention can be effectively utilized in practical terms. In practical terms, the direction (angle) of the prism (plate) is determined by looking at the angle and direction of the sunlight, and in light of the requirements for the range of light introduced into the window. , just change the prism plate for F half or the whole, no new design is required,
It is possible to improve sunlight, save energy, and improve the light environment simply by replacing glass without requiring changes to conventional design elements.
