Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a daylighting system using sunlight for illuminating concrete buildings such as residential buildings and office buildings.

[0002]

2. Description of the Related Art A conventional daylighting system is constructed as shown in FIG. In FIG. 2, 1 is a daylighting device, 1a is a daylighting surface thereof, 2 is a light guide duct for carrying light introduced from the daylighting device 1 into a room, and 3 is a light diffusing device. Four
Is a lighting fixture such as a light, 4a is an electric wire for the lighting fixture 4,
5a and 5b are concrete for the first floor and the second floor, for example.
Floor, 6 ceiling plate, 7 concrete floor 5a, ceiling plate 6
A space formed between them, 8 is an outer wall, 9 is a terrace (or eaves) on the upper floor (second floor) of the room, and 10 is a room into which sunlight is introduced. Note that 9a is the terrace of the room 10. As described above, the concrete floor of the conventional concrete building, for example, 5a, is constructed so as to be used only as the floor of the room 10. Therefore, the ceiling board 6 of the room 10 is the floor of the room 10. The light guide duct 2 that is provided directly below the concrete floor 5b on the upper floor (in this case, the second floor) with a narrow space 7 and is directly connected to the daylighting device 1 is arranged in this narrow space 7. . In the above-described configuration, sunlight is received by the daylighting section 1a and the light is guided to the room 10 through the light guide duct 2 and the light diffusing device 3 to illuminate the sunlight when the weather is fine. In addition, at night or in the case of rain, the room 10 is illuminated by the lighting device 4 such as an electric light with electric power from a commercial power source (not shown).

[0003]

However, in the above arrangement of the daylighting system, the daylighting device 1 must be provided in the upper part of the room 10, and in that case, the daylighting surface 1a of the daylighting device 1 is located on the terrace on the upper floor ( Since it becomes a shadow of the visor 9, the lighting device 1 must be installed such that the lighting surface 1a projects further outward than the tip of the terrace 9 as shown in FIG. The main body also became larger and the appearance of the building was impaired. In addition, the above-mentioned concrete floor 5
Since the space 7 between the ceiling plate 6 and the ceiling plate 6 is very narrow, it is difficult to install a daylighting system that requires a large diameter with a normal layout. If you dare to install a large diameter, The ceiling must be lowered and the space must be provided, which causes a problem that the room has a low ceiling and the space is reduced. Furthermore, electrical wiring for the lighting fixture 4 must be provided in the narrow space 7 at the same time, which is a problem in terms of safety. It is an object of the present invention to provide a daylighting system that solves the above-mentioned problems (problems) of conventional ones.

[0004]

In order to solve the above-mentioned problems, the present invention provides a concrete building having a double concrete floor formed by an inverse slab method or the like, in a terrace side of the room. A daylighting device was installed in the room, and the base of the light guide duct directly connected to the daylighting device was arranged in the space formed between the double concrete floors to guide light to the room.

[0005]

According to the present invention, the base of the light guide duct directly connected to the daylighting device is connected to the double concrete of the concrete building.
Since it is installed in a wide space formed between the floors, it is possible to install a large-diameter lighting device and a light guide duct, which makes it a highly efficient lighting system. Is not damaged.

[0006]

EXAMPLES The present invention will be specifically described below with reference to an example shown in FIG. In FIG. 1, 11 is a lighting device, 11
a is a lighting surface, and the lighting device 11 is installed on the outer wall 18 side of the upper part of the terrace (or eaves on the lower floor) 19 of the room 20, and the base 12a of the light guide duct 12 directly connected to the lighting device 11 is As shown in the figure, it is installed in the space 21 formed between the double concrete floors 15a and 15c formed by the reverse slab method, and communicates with the base 12a of the light guide duct 12 to form the concrete floor. The front portion 12b of the light guide duct 12 penetrating 15c and projecting into the room 20 is equipped with, for example, a light diffusing device 13 arranged vertically along the inner wall of the room 20 as shown in the drawing. The sun rays introduced via the above are introduced into the room 20. The front part 12b of the light guiding duct 12 is preferably embedded in the inner wall in view of the room. Thus, the base portion 12 of the light guide duct 12 directly connected to the daylighting device 11
By arranging a in the wide space 21, it is possible to install the daylighting device 11 having the large-diameter daylighting surface 11a and the light guide duct 12, which is a feature of the present invention.
The light diffusing device 13 includes a reflecting mirror and the like, and is provided at a substantially central position of the room 20 near the ceiling plate 16. Reference numeral 14 is a lighting device such as an electric lamp which is fed from a commercial power source (not shown), 14a is its electric wire, 16 is a ceiling plate, 17
Is a narrow space formed between the ceiling plate 16 and the concrete floor 15b on the upper floor, and the electric wire 14a is wired in the space 17. In the above configuration, during fine weather, sunlight is received by the daylighting unit 11a, and this light is guided to the room 20 via the light guide duct 12 and the light diffusing device 13 to perform illumination. In this case, the space 21 in which the base 12a of the light guide duct 12 is installed
Is a large space, and since the daylighting device 11 and the light guide duct 12 can each have a large diameter, efficient daylighting / transportation is possible. It should be noted that, at night or in rainy weather, the power from a commercial power source (not shown) can be used to power the room 2 by lighting equipment 14 such as an electric light.
Lighting of 0 will be performed. In the above embodiment, for simplification, an application example of the daylighting device to one room in the concrete building is shown, but the daylighting device and the light guide duct are similarly provided to other rooms on each floor. It can be applied by For a plurality of rooms on the same floor owned by the same owner, a light guide duct connected to one daylighting device may be arranged in a branched manner or may be connected to another transport means such as an optical fiber. The sunlight rays introduced by the combination can be guided to each required room.

[0007]

As described above, the present invention is configured such that the light guide duct directly connected to the daylighting device is arranged in the space formed between the double concrete floors equipped in the concrete building. Therefore, it has the following excellent effects. Since the space between the double concrete floors is wider than the conventional narrow space under the ceiling, the base of the light guide duct can be installed in this wide space, and thus a large diameter lighting device and It is possible to install a light guide duct, and as a result, lighting efficiency and transport efficiency can be greatly improved. In the conventional type, the lighting surface of the lighting device is a terrace.
Since it is arranged on the lower side of the building, the lighting surface is projected to the outside of the building greatly and the view of the building is impaired. However, in the present invention, the lighting surface is installed on the outer wall on the upper side of the terrace. The view of the building was also greatly improved because it was placed along the line. The narrow space formed between the ceiling and the concrete floor on the upper floor can be used exclusively for the electrical wiring of the lighting equipment using a commercial power source, which improves safety.
