To provide a lighting device capable of lighting a room away from a window.

[Disclosure of invention]

In the lighting device of this invention, a lighting duct whose inner surface is a highly reflective surface is installed in a storage space of a building, and the lighting duct has a lighting opening opened to the outside and a light emitting opening opened into the room.

According to the configuration of this invention, a lighting duct whose inner surface is made of a highly reflective surface is provided, so that sunlight can be brought into rooms that are away from the windows of the building. In this case,
Since the lighting duct is provided in the storage space, the lighting duct is not exposed to the living room, etc., and the aesthetic appearance of the room is maintained, and it can also be installed in buildings where there is not enough space to install the lighting duct in the ceiling.

Embodiment A first embodiment of this invention will be described based on FIGS. 1 to 5. In this lighting device, a lighting duct 1 whose inner surface is a highly reflective surface is provided in a storage space 3 of a building 2, and a lighting opening 4 of this lighting duct 1 is provided outdoors, and a light emitting port 5 is provided inside a room 6. It is something. Building 2 is an apartment complex such as a condominium.
The storage space 3 consists of a closet. The storage space 3 is partitioned into three levels, upper and lower, by two shelf boards 7 and 8, and the lighting duct 1 is provided in the top bag section of the top level.

A lighting opening 4 of the lighting duct 1 opens into a window 10 formed continuously from the storage space 3 to an adjacent room 9. Portion 10a inside storage space 3 of window 10
Since there is no need to open the room 9, the part 10b inside the room 9 is set as an open/close type. It is preferable to provide a curtain over the window 10 in the middle part of the storage space 3 so that the inside cannot be seen from the room.

The light emitting port 5 of the lighting duct 1 is connected to the window 1 of the storage space 3.
It is located on the partition wall 11 facing 0. Since the light emitting port 5 does not need to be opened or closed, the glass plate 12 is provided in a closed state.

The lighting duct 1 is framed by a longitudinal frame member 14 and a circumferential frame member 15 as shown in FIG. 3, and has mirrors 16 (FIGS. 4 and 5) on four sides to form a rectangular tube shape. The longitudinal frame member 14 and the circumferential frame member 15 are made of extruded aluminum or the like. These frame materials 1
A gasket 17 is provided between the mirror 16 and the mirror 16 to prevent dust from entering the lighting duct 1.

According to this configuration, since the daylighting duct 1 is provided with an inner surface having a highly reflective surface, sunlight can be brought into the room 6 that is away from the window 10 of the building 2. In this case, since the lighting duct 1 is provided in the storage space 3, the lighting duct 1 is not exposed into the room 9, and the beauty of the interior of the room 9 is maintained. It can also be installed in buildings that do not have enough space to install lighting ducts in the ceiling. The efficiency of the lighting duct 1 increases as the cross section becomes larger.
Also, the shorter the overall length, the larger the duct, but since it is installed in the storage space 3 such as a closet, it is easier to take a larger cross section of the lighting duct 1 than when it is installed in the ceiling, and the illuminance that can be obtained can be increased. The top level of storage space 3 is relatively infrequently used, so lighting duct 1
There is little harm caused by the narrowing of the storage space 3 due to the provision of the storage space 3.

The light emitting port 4 of the lighting duct 1 is aligned with the existing window 10, so there is no need to provide a separate window for lighting, and construction is simple. Further, since there is no need to provide an opening for opening the lighting port 4 of the lighting duct 1 on the beam or outer wall of the existing building 2, there is no problem of reducing the strength of the building 2. Furthermore, since the storage space 3 is provided with a window 10, by opening the curtains when the weather is nice, the inside of the storage space 3 can be sterilized and there is no need to take the futon out. This has the advantage of providing internal light and heating.

FIGS. 6 and 7 show a second embodiment. In this example, the lighting duct 1' is made up of a horizontal duct part 1a whose one end becomes the lighting opening 4, and a vertical duct part 1b rising vertically from the other end of the horizontal duct part 1a. A light emitting port 5' is provided in the vertical wall portion of 1b. Both duct parts 1a,
At the corner between 1b, a reflecting mirror 18 for guiding light downward is provided at an angle of inclination of approximately 45°. Vertical duct part 1
The lower end of b reaches the middle shelf 7 of the storage space 3. The light emitting port 5' is provided with a glass plate 19 fitted thereinto. The size of the light emitting port 5' is the same as that of the storage space 3.
It is assumed that the height is approximately the same as the height of the middle row. 16' is a mirror.

With this configuration, the light emitting port 5' is provided in the vertical wall portion of the vertical duct portion 1b, so that the light emitting port 5' can be made large. Moreover, the vertical position of the light emitting port 5' is
It can be set arbitrarily regardless of the position of the horizontal duct portion 1a. Furthermore, since there is a mirror 16' in the vertical duct portion 1b provided with the light emitting port 5', it can be used as a full-length mirror when not used as a lighting window. Other structural functions are similar to those of the first embodiment.

8 to 10 show a third embodiment.
In this example, in the second embodiment, a shelf 20 is provided inside the vertical duct portion 1b, and an opening/closing door 21 is provided at the light emitting port 5'. The opening/closing door 21 is provided with a glass plate.

In this configuration, since the opening/closing door 21 is provided, the inside of the vertical duct portion 1b can be used as a greenhouse, a drying room, or a sterilization room. In this case, since the shelf 20 is provided, it can be used to place ornamental plants, etc., an aquarium for tropical fish, and is easy to use for drying and sterilizing laundry. Note that the shelf board 20a of the shelf 20 is preferably made of a material that can transmit light, such as a net or a transparent plate, and the frame 20b of the shelf 20 is preferably a pipe board or rod-shaped material that does not block light.

In the above embodiment, the storage space 3 is a closet in a Japanese-style room, but it may also be a closet or the like. In addition, the lighting opening 4 of the lighting duct 1, 1'
The lighting duct 4 does not necessarily need to be located at the window 10, and the lighting duct 4 may be passed through an opening separately formed in the outer wall.

11 to 13 show a fourth embodiment. In this example, a lighting duct 31 is installed vertically through the roof 2a on the 2nd floor 2F and the floor 2b on the 2nd floor 2F of a building 2', and a lighting duct 34 that opens outdoors at the upper end is connected to a room 36 on the 1st floor 1F at the lower end. A light emitting port 35 is provided. The lighting opening 34 is provided with a dome-shaped light-transmitting cover. 2nd floor of lighting duct 31
The portion penetrating 2F is within the storage space 33 provided along the wall of the room 39. The duct 31 has a highly reflective inner surface formed by mirror coating or the like. When configured in this way, 1 from the top of the roof 2a
Lighting can be brought into Room 36 on the 1st floor.

(Effects of the invention) The lighting device of this invention is equipped with a lighting duct whose inner surface is made of a highly reflective surface, so it is possible to bring in light into the room that is away from the windows of the building.In this case, a lighting duct is installed in the storage space. Therefore, the lighting duct is not exposed to the living room, etc., and the beauty of the interior of the room is maintained, and the lighting duct can be installed even in buildings where there is not enough space to install the lighting duct in the ceiling.
