Description of the Related Art In the above-mentioned building having an unspecified number of visitors, if the floor area of a room is more than a certain level, smoke emission that emits toxic smoke and gas to the outside in case of a fire should be taken. Equipment installation is required. In addition, the smoke exhaust device is a smoke exhaust device with a ceiling that discharges smoke and the like to the outside through a smoke exhaust duct from a smoke outlet provided on the ceiling, and a smoke exhaust device that is provided on windows and walls to directly emit smoke to the outside. There is a skylight-type smoke exhaust device that is classified as a wall-mounted smoke exhaust device that discharges air.

[0003] A conventional skylight type smoke evacuator has a lower frame provided at a ceiling opening, and an upper frame which can be moved up and down with respect to the lower frame using an X-arm or the like. Normally, the upper frame is in the lowered position, the ceiling opening is closed by glass or transparent resin provided on the upper frame, and functions as a lighting window. In a fire, the upper frame and the lower frame are raised by raising the upper frame. A gap is created between them to function as a smoke outlet. The lifting and lowering of the upper frame is performed by an automatic opening / closing device that drives the X-arm using a lifting motor.

[0004] On the other hand, as a device for efficiently guiding sunlight from a roof into a room, a solar lighting device is known. This device changes the direction of a built-in flat prism according to the altitude and azimuth of the sun by a rotary driving device using a prism driving motor so that sunlight is most efficiently guided into a room. The ceiling-type smoke exhaust device and the solar lighting device are both devices that can be mounted on a roof, but have conventionally been provided as separate facilities.

[0005]

However, in the case where the ceiling-type smoke exhaust device and the solar lighting device are installed as separate facilities, the structure of the roof becomes complicated, and the cost is increased since the roof is separately installed. In addition, the automatic opening / closing device provided in the smoke exhaust device and the rotary drive device provided in the solar lighting device both require a power source, but when a commercial power source is used, electrical work such as wiring is required. Also contributes to the cost increase.

The present invention solves the above-mentioned problems (problems) of the prior art, and is an apparatus having a smoke exhaust function and a sunlight collecting function without using a commercial power supply which is an external power supply. It is an object of the present invention to provide a solar lighting device with a smoke exhaust function that can be driven.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a solar lighting device with a smoke exhaust function according to the present invention has a ceiling formed on a roof of a building. It has a lower frame attached to the opening, and an upper frame attached to the lower frame so as to be able to move up and down.
One or a plurality of lighting prisms arranged at predetermined intervals, a transparent cover covering the lighting prism, a rotation driving device for rotating the lighting prism, and an appropriate rotation angle according to the position of the sun for the lighting prism And a control device for controlling the rotary drive device so that the solar battery serving as each power source of the rotary drive device, the control device, and the elevating mechanism of the upper frame is provided in the upper frame or the lower frame.

[0008] According to the above configuration, when the upper frame is at the lowered position, it functions as a normal sunlight collecting device, and can efficiently guide sunlight into the room according to the position of the sun. In addition, when the upper frame rises, a space is formed between the upper frame and the lower frame that functions as a smoke outlet, and in the event of a fire, smoke or gas can be discharged outside from this space. Furthermore, since the rotary drive device, the control device, and the elevating mechanism of the upper frame are driven by solar cells, wiring work at the time of installation is not required, and electricity costs at the time of operation are not required.

It is desirable that the solar cell be arranged in the transparent cover of the upper frame.

In order to raise and lower the upper frame, an automatic opening and closing device such as an X-arm using a motor for raising and lowering may be employed.
