い。This direct light is one component when the sunlight is divided into direct light and diffused light, and the former is absorption and scattering by air molecules, water, water vapor and fine particles contained in the atmosphere of the earth. Is the light that directly escapes to the ground and the latter is scattered in the atmosphere regardless of the direction of the sun,
Light that reaches the earth from all directions in the sky. The intensity of these two lights on the ground depends on the absorption and scattering properties of the atmosphere, the position of the sun, and the direction of the light-receiving surface. The former is directional, while the latter is diffusive. Therefore, there is a big difference in the arrival amount on a specific surface. In other words, since direct light is obtained only on the surface that the sun can see, its value varies greatly depending on the orientation of the surface, while diffuse light is obtained on all surfaces that the sky can see, so its value is Although it depends on the desired size of the sky, the difference in the orientation of the surface is relatively small.

散光のみの室内への導入が好ましいと判断される。As described above, sunlight is roughly classified into direct light and diffused light, and the light that feels dazzling is direct light with a strong directivity. Therefore, when introducing sunlight into a room, diffused light excluding this direct light is used. It is judged that it is preferable to introduce only one into the room.
