Description

[Detailed description of the invention] The present invention relates to the improvement of a ceiling lighting device, in which a lighting section 2 is provided in the ceiling section 1, and a large number of louver plates 3.3.3 for opening and closing the lighting section 2 are installed in the lighting section 2. Installed in parallel and rotatably,
Out of the opposing ends of the adjacent louver plates 3, 3, one of the louver plates 3 has a cut-out thin film 9 with an upper corner cut out, and the lower edge of the other louver plate 3 has a cut-out thin film 9. The lower surface of each louver plate 3, 3 in a closed state in which the lower cut thin film 10 of one louver plate 3 and the lower cut thin film 10 of the other louver plate 3 are engaged with each other. A joint 11 with approximately the same joint width of the ceiling finishing material 4 is formed between the ends of the ceiling finishing material 4 so that the finish of the louver board 3 is the same as that of the ceiling finishing material 4, and when the louver board 3 is in a closed state, the bottom surface of the louver board 3 is This relates to a ceiling lighting device located above the lower surface of the ceiling finishing material 4.

A problem with ceiling lighting devices called top lights is that the material of the opening/closing part of the lighting section is different from the finishing material of the lighting section, which does not harmonize with the design and makes the presence of the lighting section visible even when closed. was there.

The present invention was devised in view of the above points, and its purpose is to adjust the amount of light by making the louver board rotatable, so that the finish of the louver board is the same as that of the ceiling finishing material. To provide a ceiling lighting device that does not make the user feel the presence of a daylighting part even though the daylighting part exists and can be in the same state as a ceiling without a daylighting part.

The present invention will be explained in detail below with reference to Examples.

The atrium has a ceiling part 1 like a ceiling with a lighting part 2.

In this lighting section 2, a transparent body 6 such as glass is disposed between the upper parts of opposing lighting section caps 5, and light is brought in through this transparent body 6.

A louver plate support frame 7 is provided on the opposing surface of the opposing lighting part 5, and a large number of louver plates 3 are rotatably mounted between the louver plate support frames 7.

The louver plate 3 is rotated by a drive device 8 such as a motor, and for example, by moving a wire 15 by the drive device 8, the louver plate 3 can be rotated by following the movement of the wire 15. Alternatively, the louver plate 3 may be rotated via a gear mechanism.

Here, the reason why the louver plate 3 is rotated by a drive device 8 such as a motor is that the switch of the drive device 8 is provided below, so that the opening and closing of the lighting section 2 at a high place such as the ceiling section 1 can be done by moving the louver plate 3 downward. This is to make it easier for anyone to do it.

Furthermore, by selecting the rotation angle of the louver plate 3, the amount of daylight can be freely adjusted.

The louver board 3 has the same finish as the ceiling finishing material 4, and among the opposing ends of the adjacent louver boards 3, a soil cut thin film 9 is provided at the end of one of the louver boards 3, and a thin film 9 is provided at the end of the other louver board 3. A lower cutting thin film 10 is provided in the lower part, and when the louver plate 3 is closed, the soil cutting thin film 9 and the lower cutting thin film 10 are disposed in the lower part as shown in FIG.
and are engaged with each other.

In this case, as shown in FIG. 3, a joint 11 may be formed between the ends of the lower surfaces of adjacent louver plates 3.
The width of this joint 11 is preferably made equal to the joint width of the ceiling finishing material 4.

Further, as shown in FIG. 3, if the upper surfaces of the opposing ends of the adjacent louver plates 3 are formed into inclined surfaces 12, the louver plates 3 can be closed smoothly when the louver plates 3 are rotated and closed.

In the figure, 13 is a column, and 14 is a drive device storage section.

In this invention, as described above, a lighting section is provided in the ceiling part, and a number of louver plates for opening and closing the lighting section are rotatably attached to the lighting section, so that by rotating the louver plates, Not only can you adjust the amount of light coming from the ceiling's lighting area, but since the louver board has the same finish as the ceiling finishing material, you can close the louver board when you don't need the lighting from the ceiling's lighting area. The lighting area has the same finish as other ceiling finishing materials, so there is no sense of incongruity, and even though there is a lighting area, the presence of the lighting area is not felt. Both can be selected to appear.

Further, a soil cut thin film is formed at the end of one of the opposing ends of the adjacent louver plates, and a lower cut thin film is formed at the end of the other louver plate, and the soil cut thin film and the lower cut thin film are formed at the end of the other louver plate. Since a joint width approximately equal to the joint width of the ceiling finishing material was formed between the ends of the lower surface of each louver board in the closed state where they were engaged, the joint width formed between the ends of each louver board was the same as the joint width of the ceiling finishing material. This makes it possible to make the single louver in the daylighting area even more inconspicuous as it blends in with the lighting.Moreover, it is possible to finish the ceiling by using the gaps between each louver as joints, which cannot be eliminated in a closed situation like this. It has the advantage that there is no need for treatments such as making the gap itself less noticeable by blending it in with the joints of the wood.

In addition, when the louver board is closed, the bottom surface of the louver board is positioned above the bottom surface of the ceiling finishing material, so the louver board is positioned above the ceiling finishing material, so that the part with the louver board is higher than the ceiling finishing material. The louver board is recessed upward, and the part with the louver board has an appearance that constitutes a so-called picture frame ceiling structure, and the part with the louver board can be integrated with the ceiling in appearance as a picture frame ceiling part, This can further reduce the feeling that the ceiling is a different part from the ceiling.

Claims (1)

[Scope of utility model registration request] A lighting section is provided in the ceiling, and within this lighting section, a large number of louver plates that open and close the lighting section are arranged in parallel and rotatably attached, and one of the opposite ends of the adjacent louver plates is installed. At the same time, a lower corner thin film is formed at the end of the other louver plate, and a lower cut thin film is formed at the end of the other louver plate. In the closed state where the lower cut thin film of the louver board is engaged, a joint width approximately equal to the joint width of the ceiling finishing material is formed between the ends of the bottom surface of each louver board, and the finish is the same as that of the ceiling finishing material of the louver board. The ceiling lighting device is constructed such that the lower surface of the louver board is located above the lower surface of the ceiling finishing material when the louver board is in a closed state.
