JPH038207A - Sun light introducing method - Google Patents

Abstract

PURPOSE:To introduce sun light into a basement or the like by arranging a convex lens on the ground side, collecting and guiding sun light with optical fiber cables, and diverging the light with a concave lens arranged on the basement side. CONSTITUTION:Sun light is collected with a convex lens 1 and sent to a basement 3 through many bundled optical fiber cables 2. A concave lens 4 is arranged on the basement 3 side in response to cables 2, and the sun light sent through cables 2 is diverged and diffused by the lens 4 and uniformly introduced into the basement 3. The sun light can be received in the basement 3, and health is maintained and workability can be improved with the simple method.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for introducing sunlight into a basement or the like where it is difficult to take in sunlight.

[Conventional technology]

Conventionally, no means have been known for allowing sunlight to enter a basement or the like.

[Problem that the invention seeks to solve]

As is generally known, the basement is a completely dark room, so a lot of lighting is required and a lot of effort is put into lighting. Therefore, it is of course difficult in terms of costs, but it also affects work efficiency, especially since it cannot be exposed to the same sunlight as above ground, so the awareness that it is underground has an impact on work efficiency. It also has negative effects on the body.

[Means for solving problems]

In view of such circumstances, and in order to deal with this problem, the present invention is provided for the purpose of introducing sunlight from the ground into basements etc. using optical fibers. This converged sunlight is sent to the basement through an optical fiber, and then diverged by a concave lens, allowing work to be carried out indoors under the same sunlight as on the ground.

〔Example〕

Next, an embodiment of the sunlight intake method according to the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a convex lens, and the convex lens 1 is used to converge sunlight, and the converged solar rays are sent to a room 3 located underground through a large number of converged optical fiber cables 2. A concave lens 4 is arranged on the basement 3 side corresponding to the optical fiber cable 2, and the sunlight sent through the optical fiber cable 2 is diverged and diffused by the concave lens 4, allowing the light to enter the room 3 evenly. .

[Effect]

As described above, in the present invention, sunlight is converged by a convex lens placed on the ground side, sent to the basement 3 via an optical fiber cable 2 corresponding to the convex lens 1, and is diverged by the action of a concave lens 4 placed on the basement 3 side. This is to irradiate the inside of the basement 3 with the same light rays as the sunlight above ground.

〔effect〕

As mentioned above, the combination of a convex lens, an optical fiber, and a concave lens allows sunlight to be sent down to the basement, allowing the basement to receive the same irradiation as the sunlight received above ground, which is not only good for health but also for work efficiency. Fully elated,
Moreover, it can be introduced with a simple device and has excellent effects.

[Brief explanation of drawings]

The drawing is an explanatory diagram of the method for taking in sunlight according to the present invention. 1 ~ Convex lens 2 ~ Optical fiber cable 3 ~ Basement
4~Concave lens

Claims (1)

[Claims] A convex lens is placed on the ground side to converge sunlight, and this converged sunlight is matched with a converging optical fiber cable that passes through the basement where the tip end is taken in. Also, a concave lens is placed on the optical fiber cable on the basement side. A method of taking in sunlight, which is characterized in that the sunlight that is sent is dispersed.
