Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent body which constitutes a lighting window mainly at an opening such as a ceiling, a floor or a wall surface of a general building, and more specifically to an air gap between two plate materials. Due to the optical characteristics of the refraction columns arranged in the layers, in a transmissive body that mainly selectively adjusts the amount of sunlight or the range of sunlight for sunlight with different heat amounts by using the difference in the angle of incidence or the light is blocked. The structure of the refraction column.

[0002]

2. Description of the Related Art Conventionally, a single-layer plate glass using a plate glass such as a template glass and a float plate glass, or an air layer is provided between two plate glasses at an opening such as a ceiling of a general building. A multi-layer plate glass or a laminated plate glass provided with a resin layer, or a plate glass of which the transparent glass plate is replaced by a transparent synthetic resin plate to form a daylighting window to illuminate indoor space with sunlight or light. Although the light etc. were lit as it is, especially when illuminating sunlight, which is natural light, it is comfortable because the amount of heat of sunlight differs depending on the annual and diurnal movements of the sun, that is, changes in the four seasons and time zones. It is necessary to artificially adjust the lighting in order to create a comfortable living space.

In view of this kind of problem, the transparent body of the present invention has a refraction column arranged in a plane in order to show a comfortable living space and at the same time a new decorative effect in the living space. The transparent body is used, and its outline and problems to be solved in the present invention will be presented below.

As shown in FIG. 4, the transmissive body according to the present invention includes, for example, two transparent plate members 21a. It is possible to form the transmissive body 21 in which the refraction columns 22 having a plurality of lengths are arranged between the portions 21b.

In this case, since the internal refraction column 22 gives an optical change such as scattering, reflection, refraction, color change, etc. to incident light such as sunlight or illumination light, it is used as a lighting window of a general building. And the like, incident light S1. S
2. S3 is the refracted light X1 that has passed through the inside of the refraction column 22 at a predetermined incident angle αβγ, the refracted light X2 that has partially passed through the inside of the refraction column 22, and the reflected light Y that has been partially reflected.
2. The reflected light Y3 that is totally reflected is generated.

Therefore, by using this type of transmissive body 21, sunlight incident on the transmissive body 21 can be selectively lit by utilizing the difference in the incident angle and by adjusting the amount of lighting and the range of lighting. You can

That is, in FIG. 4, when the left end of the transmissive body 21 is horizontally installed on the ceiling surface with the right end facing north, the incident light S1 has a small amount of heat when focusing on the annual movement of the sun. Since the sunlight in winter and the incident light S3 can be matched with the sunlight in summer having a large amount of heat, and the incident light S2 can be matched with the sunlight in spring and the autumn having a substantially intermediate amount of heat, respectively. The sunlight in winter with a small amount of heat is applied with a daylighting function of collecting the entire amount of the incident light S1 as the refracted light X1,
The sunlight in the spring and autumn produces a reflected light C2 in a part of the incident light A2, and a part of the incident light A2 is used as a refracted light B2. By applying the light blocking function of generating the reflected light S3 to the entire amount, it is possible to effectively adjust the balance of the amount of heat in the room due to daylighting.

However, as described above, the refraction column 22 which produces the optical effect is the refraction light X1. When the light is collected as X2, there are cases where the light is concentrated on a part of the indoor side or a spectral spectrum is generated, and when these are observed from the indoor side, they are excessively dazzling or on the wall surface in the room. There is a possibility that the shadow of the refraction column may be projected or that a part of the indoor article may be discolored.

SUMMARY OF THE INVENTION In view of the above reasons, the main object of the present invention is to form a diffusing surface by sandblasting, etching, coating, etc. on the surface of a refraction column used in this type of transmissive body, and to collect light and obtain a spectral spectrum. The purpose of this is to prevent the occurrence of light and realize more uniform natural lighting.
