2. Description of the Related Art A louver is installed on the lower side of a lighting device installed on a ceiling, which is generally used in building construction. However, such a louver is made of metal or plastic. Blades such as a single plate or elongated body having a U-shaped or V-shaped cross section are arranged in parallel in a comb shape,
Or, it is formed by crossing vertically and horizontally in a grid pattern, and by configuring by appropriately setting the color, material, height, thickness, etc. of the blade, the lighting effect according to various usage environments and purposes of the indoor space And gave decorativeness.

[0003]

However, since the conventional illumination louver is constructed by arranging blades at equal intervals, the comb tooth pattern or the lattice pattern of the entire louver is uniform. However, there was a lack of variability and design, and there was a tendency.

In view of the above problems, the present invention provides the louver with a variability on the entire inner surface of the louver by constructing the louver with the blades arranged in parallel at different intervals. It is an object of the present invention to provide a louver for ceiling lighting which is capable of being made.

[0005]

In order to solve the above problems, the louver for ceiling lighting according to the present invention may have a plurality of blades (plate-shaped or U-shaped cross-section, V-shaped or any other shape, and the opening of the louver). In the louver for ceiling lighting having a configuration in which the vertical and horizontal partition forming members that form the () are arranged side by side in parallel, a blade interval of a part thereof is set to be wider or narrower than a blade interval of other parallel parts. The feature is that the entire louver is configured to change the width of the blade.

Further, the louver for ceiling lighting of the present invention is a louver for ceiling lighting having a constitution in which a plurality of blades are arranged in parallel, and a blade interval of a part of the louver is higher than a blade interval of another parallel part. And set it wide or narrow,
Another feature is that the blade width is changed over the entire louver by interposing a blade interval that gradually changes between the widths.

The above-mentioned part may be provided at one place in either or both of the vertical and horizontal directions, or may be provided as a plurality of parts. Further, the blades arranged side by side can be set such that the change in width as described above of both blade intervals in the row and row is the same pattern as each other, or the change in width is different from each other. Can be set. Furthermore, it is also possible to set the blade intervals in any one of the vertical and horizontal rows to be equal, and to set the wide or narrow change in the blade intervals in the other row.

[0008]

The partition changes of the blades having different intervals appear on the lower surface of the louver to form a gradation pattern, which causes variability on the ceiling surface. The change becomes smoother and continuous by interposing the interval in which the width gradually changes between the widths of the blade intervals. The change can be made to be the same pattern in both the vertical and horizontal directions, but the variability is further increased by using different patterns. It is also possible to give directionality by changing the spacing in only one of the vertical and horizontal directions.
