Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a daylighting and ventilation system used for lighting and air conditioning in residential buildings, office buildings, and the like.

[Prior Art] Conventionally, a lighting device that guides outdoor light into a room has
As shown in Publication No. 96914, sunlight is collected by a lens or the like and transmitted to a suitable room using an optical fiber, and a light diffusion device is used at the exit of this optical fiber to introduce the sunlight into the required room. .

[Problems to be Solved by the Invention] However, in the conventional technology described above, the lighting in buildings is only directed to rooms where sunlight does not directly shine; As for ventilating the required room air with the same equipment and making it a better living space.

It was something that had not been thought of at all.

In addition, conventional daylighting devices used a Fresnel lens to collect light and send it through an optical fiber, but with this method, the angle of incidence and amount of light change as the sun moves in the sky. The problem was that the lighting efficiency was poor.

For this reason, it was necessary to track and control the angle of the introduction window in response to the movement of the sun, and in this case it was necessary to provide an expensive tracking mechanism that was more expensive than a power source and control mechanism.

Another conventional method was to combine mirrors and send the reflected light through a duct.

With this method, light must be sent in one direction using only a combination of mirrors, and a deep lighting area is required.
As a result, the thickness of the lighting section is increased, making it difficult to manufacture a lighting device that can be mounted on the roof of an existing house.

An object of the present invention is to provide a daylighting and ventilation system that solves the above-mentioned problems of the conventional system.

[Means for Solving the Problems] The present invention provides a lighting system that guides outdoor light indoors.
The present invention relates to a lighting system that uses a light intake body formed by arranging a plurality of rows of prism-shaped protrusions on the upper surface of a lighting window material made of a transparent plate as an introduction means for guiding outdoor light indoors.

In this case, the prismatic protrusions are arranged in multiple rows in the north-south direction, with the width direction of each protrusion unit being oriented in the east-west direction, and the light intake body is placed at the bottom of the tank. It is desirable to do so.

Further, in this case, it is desirable to provide a lighting system in which a thin transparent plate is provided on the upper surface of the protrusion.

Furthermore, it is desirable that the lighting system introduce light into the room by connecting an optical fiber to the light intake body.

Further, by connecting a light guide duct to the light intake body, a lighting system can be provided in which light is introduced into the room.

Furthermore, it is possible to provide a lighting system in which the light intake body is configured by a combination of a plurality of transparent plates each having a light introduction surface with oblique entrance angles of at least eastward, westward, and upward.

Furthermore, a lighting system may be used in which the light introduction surface of the light intake body is formed so that its cross section in the east-west direction is a convexly curved surface.

Furthermore, it can also be used as a lighting device that guides outdoor light indoors.
This lighting device consists of a light collecting device that collects the light to be taken in, a light guiding device that guides the collected light, and a light diffusing device that diffuses the light from the light guiding device into the room. Functions can be added to create a lighting/ventilation system in which the light diffusion device and light guiding device are connected to each other to introduce light and air into each room.

[Function] The device of the present invention is a lighting device that guides outdoor light and, if necessary, an air supply/discharge function is added to a room that receives light from the lighting device. A light-intake body is constructed using a transparent plate so as to have a large number of protrusions or a large number of light-introducing surfaces on the upper surface of a lighting window material, which is a portion into which light is introduced.

By using the refractive index of light from these protrusions or light introduction surfaces, the thin structure allows light to be introduced from various directions, allowing light from outside to be changed in the direction of light introduction depending on the movement of the sun. It is now possible to introduce light even if there is a road between roads, and it can also be installed on the roof of an existing building.

Therefore, with this system, lighting efficiency inside the building hardly decreases in the morning or evening, and ventilation is also effective.

Can be done properly.
