Abstract

PURPOSE:To provide a lighting system in which light feeding efficiency is enhanced by effectively utilizing the outer wall and the floor of a building. CONSTITUTION:This system is provided with lighting devices 8, 16 and 21 for introducing solar light and light guiding devices 13, 19 and 26 for guiding the outdoor light introduced by the lighting device to the rooms 2-7 of the building 1. By arranging the devices 8, 16 and 21 in the outer wall 22 and/or the floors 9 and 18 of the building 1, the devices 13 and 19 are made shorter in length than the case that the lighting device is arranged only on a roof so that the light feeding efficiency is improved. Besides to that, the strength of the roof need not be made high, and the appearance of the building 1 is not spoiled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a daylighting system for guiding outdoor light into a building such as a house or a building.

[0002]

2. Description of the Related Art A daylighting device that takes in outdoor light into a room is generally installed on the roof of a building, as disclosed in Japanese Patent Laid-Open No. 64-21402.

[0003]

However, when the lighting device is installed on the roof, there is a risk of rain leakage due to construction errors and the strength of the roof must be increased to support the weight of the lighting device. However, there was a drawback that the construction cost was expensive.

In addition, in an office building or the like, there are many rooms where it is desired to take in outdoor light, but there is a risk that the number of rooms will be limited due to the limited rooftop area. Since a long light guide device such as a fiber or a duct that guides light to a far away room such as the above is required, the installation work of the light guide device is complicated and the light transport efficiency is deteriorated.

In view of the above points, the present invention has an object to provide a daylighting system which is easier to construct and has improved light carrying efficiency as compared with a conventional system in which a daylighting device is installed on a roof of a building. is there.

[0006]

In order to solve the above problems, the present invention provides a daylighting device that takes in outdoor light and a light guiding device that guides the outdoor light taken in by the daylighting device into the room of a building. In the provided daylighting system, the daylighting device is arranged on the outer wall and / or floor of the building.

[0007]

According to the present invention, a daylighting device arranged on an outer wall of a building, a daylighting device arranged on an outdoor floor such as a balcony or a veranda of a building, or a floor in a room where outdoor light shines. The outdoor light taken in by the arranged daylighting device is guided into each room by the light guide device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic sectional view of a house equipped with a daylighting system.
Building 1 has a living room 2 on the first floor facing the south side, a dining room 3 on the first floor on the north side, and a children's room 4 on the second floor facing the south side.
A child room 5 in the center of the second floor, a bedroom 6 on the north side of the second floor, and a basement 7 are provided.

Reference numeral 8 is a floor 9 in the room where the sunlight in the living room 2 is exposed.
In the indoor floor type daylighting device arranged in, the composite prism 10 including a plurality of horizontal prisms 10a, 10b, and 10c as shown in FIG. It is composed of a transparent tempered glass 11 and a reflecting mirror 12 that changes the direction of the sun rays transmitted through the composite prism 10.

Reference numeral 13 is a light guide device connected to the indoor floor type daylighting device 8, and the inner surface is a reflection wall, which is formed of a light guide duct or an optical fiber which can carry sunlight and also introduce outside air. A light diffusing device 14, 1 provided on the ceiling of the dining room 3 and the basement 7 through the floor, the ceiling and the inside of the wall.
It is connected to 5.

Reference numeral 16 denotes an outdoor floor type daylighting device arranged on an outdoor floor 18 such as a balcony on the second floor or a veranda 17.
It has the same configuration as the lighting device shown in FIG.

Reference numeral 19 denotes a light guide device connected to the outdoor floor type lighting device 16, which is formed of a light guide duct, an optical fiber, or the like as described above, and passes through the inside of the ceiling to form a light diffusing device 20 in the living room 2. It is connected.

Reference numeral 21 denotes an outer wall type lighting device arranged on the outer wall 22 of the building 1, which is a composite prism 23 composed of a plurality of vertical prisms 23a, 23b and 23c as shown in FIG.
And a transparent tempered glass 24 that covers the composite prism 23.
And a pair of reflecting mirrors 25 that change the direction of the sun rays transmitted through the plurality of prisms 23 twice.

Reference numeral 26 is a light guide device connected to the outer wall lighting device 21. The light guide device 26 is formed of a light guide duct, an optical fiber or the like as described above, and is connected to the light diffusion device 27 of the child room 4 through the inside of the ceiling. Has been done.

28 and 29 are the above-mentioned lighting devices 8, 16 and
21 is a roof-type daylighting device that is formed in substantially the same manner as 21 and is disposed on the roof 30 of the building 1, and is the above-described light guide devices 13, 19, 2
Similar to 6, the light guide devices 31 and 32 that pass through the ceiling are connected to the light diffusion devices 33 and 34 of the child room 5 and the bedroom 6, respectively.

With the above-described structure, even if the incident angle of the sunlight in each of the daylight collecting devices 8, 16, 21, 28 and 29 changes with time, the output angle of each composite prism 23 becomes constant, and each of the light guides 8 and 16. Optical devices 13, 19, 2
Sunlight is guided to the respective light diffusers 14, 15, 20, 27, 33, 34 by the light guide ducts 6, 31, 32 to illuminate the respective rooms 2, 3, 4, 5, 6, 7. Used.

As described above, the living room 2 in which sunlight is positioned near the room where the daylighting devices 8, 16 and 21 are desired to be illuminated
Floors 9 and outdoor floors 18 such as balconies and balconies 17
And because it was placed on the outer wall 22 of the building 1, the roof 3 of the building 1
Compared with the case where the daylighting devices 28 and 29 are arranged only in 0, the light carrying efficiency is improved by the length of the light guiding ducts which are, for example, the light guiding devices 13 and 19, being shortened. Since the area of the roof 30 is not limited, all the rooms can take in sunlight.

Moreover, the daylighting devices 8, 16 and 21 are attached to the floor 9,
Since the lighting devices 28 and 29 arranged on the roof 30 are dispersed on the outer wall 18 and the outer wall 22, each of the children's room 5 and the bedroom 6 can be small enough to illuminate one room, and the roof 30 can be installed. The construction cost can be reduced because the strength does not have to be increased so much.

In the above embodiment, the lighting devices 8, 16, 2 are used.
Although 1, 28, and 29 are distributed and arranged on the floors 9 and 18 of the building 1, the outer wall 22, and the roof 30, they may be arranged on only one of the floors 9 and 18 and the outer wall 22. Moreover, floors 9 and 18
In this case, since the lighting devices 8 and 16 are not conspicuous, the appearance of the building 1 is not spoiled, and particularly when the lighting device 8 and 16 are arranged on the floor 9 of the room, they are not dirty as compared with the case where they are arranged outside the room. Is less likely to drop and maintenance is easy.

[0020]

According to the present invention, since the daylighting device that takes in the outdoor light is arranged on the outer wall and / or the floor near the room where it is desired to illuminate, compared to the case where the daylighting device is arranged only on the roof. As a result, the length of the light guide device for guiding sunlight to the room can be shortened to improve the light transport efficiency, and it is not necessary to particularly increase the strength of the roof, and the aesthetics of the building can be maintained.
