Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a daylighting device provided on an outer wall of a building for reflecting natural light from above into a room and obtaining illuminance.

[0002]

[Prior art]

 In urban areas, sunlight is obstructed by overcrowding and high-rise buildings, making it increasingly difficult to illuminate houses. And in such places, it is often impossible to expect much effect by simply installing a window. For example, in a house where sunlight is blocked due to factors such as adjacent tall buildings, no matter how large the window is, there is no significant change in the amount of window light. In such a case, the top light 19 as shown in Fig. 13 which is less likely to be disturbed by the neighboring situation was installed on the roof 20, and the light from above was directly introduced into the room to illuminate it.

[0003]

[Problems to be solved by the device]

 When using the above-mentioned top light, it cannot be installed without a roof part, so it can only be installed on the top floor or lower house, and the installation location was limited. For example, there was the inconvenience that it could not be installed in a place where lighting was really desired, such as a room on the first floor of a total of two stories. Also, since direct sunlight enters the room directly, it is hot in summer and some kind of shelter is required. If the glass covering the roof surface is broken, it will fall directly into the room, which is dangerous. In addition, the structure is not simple, and there are many problems in design and construction, which often cause rain leakage. Especially when installing a top light as a part of the reform after construction, it was necessary to make a hole in the roof, and it was difficult to take measures against the rain, and the construction cost was ridiculous. The problem to be solved by the present invention is that natural light from above can be introduced from a wall with a wide installation range, it is not hot even in the summer, it is safe even if the translucent material cracks for some reason, it has good workability, and rain leakage. It is to provide a lighting device that does not.

[0004]

[Means for Solving the Problems]

 The daylighting device according to the present invention solves the above problems and is as follows. That is, the small roof part is covered with a translucent plate (1), and a reflective plate (2) for reflecting natural light and side plates (3) for fixing the translucent plate and the reflective plate are provided on both sides below the small roof part. And a light guide tube (4) for introducing the natural light reflected by the main body into the room. The main body configured in this way and the light guide tube attached to the main body are attached to the outer wall in which a hole for inserting the light guide tube is previously formed. The translucent plate (1) is a plate that has a part in contact with the outer wall on the water and has a water gradient toward the tip in order to prevent rain and to capture the upper light over a wider area. ), And protects the reflection plate (2) from dust and rain so as not to reduce the reflectance. The reflector (2) may have a flat surface, a curved surface, or other various shapes as will be shown in each of the examples to be introduced later, and the translucent light is transmitted from the portion in contact with the outer wall toward the tip. Any plate having an inverse slope to the plate (1) may be used. The light guide tube (4) is composed of an opening frame (21) for introducing the reflected light and a translucent cap (22), and is surrounded by a translucent plate and a reflective plate, and a portion in contact with the outer wall of the side plate. It can be installed in a limited range, and may be one or plural. The shape of the tube may be square or round, and the larger the area, the greater the amount of introduced light.

[0005]

[Action]

 As shown in FIG. 12, the light from above passes through the transparent plate (1), is reflected by the reflecting plate (2), passes through the introducing pipe (4), and is introduced into the room. Even when there is no direct sunlight, it reflects the skylight and guides it into the room, contributing to increasing the illuminance of the room.

【Example】

 An embodiment will be described with reference to the drawings. In FIG. 1 and FIG. 2, the portion contacting the outer wall 5 is on the water and a water-transparent plate (1) is provided with a water gradient toward the tip and a light-transmissive plate (below). A reflector plate (2) having a circular arc so as to make it easy to catch the natural light in the upper part with a gradient opposite to 1), two left and right side plates (3) for fixing them, and a light guide tube (4) It is configured. The light guide tube (4) may have various shapes such as a round shape and a square shape. It is mounted between the (6) material and the (7) material, and the hooks (9) are attached so that the light guide tube can freely move in parallel. Are up and down. Further, the front and rear parts are separated so as to correspond to the thickness of the outer wall. One is a main body, and the other has a transparent window (10) (light guide lid). The other is coupled from the room. The joint material (8) of the translucent plate (1) and the reflective plate (2) is provided with a drainage hole (11) and a ventilation hole (12) so that the condensed water of the translucent plate (1) can be exposed to the outside. Ventilation is performed to discharge the gas and raise the temperature inside the main unit. The joint material between the reflection plate (2) and the outer wall 5 is provided with a water drainage hole (11) and has a function of discharging condensed water and the like to the outside.

In the embodiment of FIG. 3, the reflecting plate having a curved section in FIG. 1 is replaced with a straight section of the reflecting plate (2), and the manufacturing process can be reduced and the cost can be reduced.

In the embodiment shown in FIG. 4, a corrugated pattern is formed on the cross section of the reflection plate (2) shown in FIG. 1, and the design effect of the light reflected in the room can be expected.

In the embodiment shown in FIG. 5, innumerable small holes are formed in the reflection plate (2) shown in FIG. 1, which not only improves ventilation in the main body but also has a design effect of light reflected indoors.

In the embodiment of FIG. 6, the light guide tube is also provided with a reflection plate (13), which has the effect of blocking direct sunlight and illuminating the interior wall.

In the embodiment shown in FIG. 7, a light guide tube (4) having a bracket-shaped light-transmitting window (14) is provided on the interior surface. At night, a light bulb or the like is placed in the main body. It can also have the function of a lighting fixture.

In the embodiment of FIG. 8, a sliding window or the like (15) is provided in the portion of the material (8) shown in the embodiment of FIG. 3 so that ventilation and ventilation in the room can be measured. Although there is (4), there is no light-transmitting light guide lid.

In the embodiment of FIG. 9, the reflector (2) of FIG. 1 is disassembled so that it can be opened and closed like a louver. By adjusting the angle of the louver, the amount of light entering the room can be controlled. In addition to being able to increase or decrease the volume, the translucent light guide cover (16) can be opened and closed to allow ventilation in the room.

In the embodiment of FIG. 10, the main body shown in the embodiment of FIG. 1 is not directly connected to the outer wall, but the reflected light is directly applied to the glass surface 17 of the window instead of the light guide tube. Thus, it is possible to eliminate the darkness of the room without making a hole in the outer wall.

In the embodiment of FIG. 11, an eave (18) is made using the daylighting device shown in the embodiment of FIGS.

[Effect of device]

 When installing the daylighting device according to the present invention, natural light from above can be introduced from the wall, so that the range of installation is wide. Most of the indirect light is reflected light, so you don't feel the heat. Moreover, even if the translucent plate is broken, it is safe because the reflective plate will receive it. Even if rain enters from the small roof (transparent plate), it will be drained through the drainage hole and will not enter the building. Further, since the shape is an eaves shape, when there is an opening at the bottom, it has the function of an eaves, that is, an effect of sun protection and rain protection. In addition, it has a simple structure and good workability.
