Embodiments of the present invention will be described below with reference to the drawings. Figures 1 to 8 show an example in which the lighting device according to the present invention is applied to the ceiling of a hotel banquet hall. Figure 1 is a perspective view of the ceiling, and Figure 2 is a view of the ceiling from below. It is a diagram.

In the figure, A is the ceiling body, and this ceiling body A has a structure in which a number of hexagonal concave surfaces B in plan view are continuously connected in a honeycomb shape, and each concave surface B has three diamond-shaped concave surfaces B. The plate-like structure 1 has a concave surface B
They are arranged 120 degrees apart from each other with the center of the The plate-like structure 1 is made of plasterboard, for example, and its surface is white so as to reflect light of all colors, and has a rough surface so as to diffusely reflect light. .

On the other hand, reference numeral 3 denotes a lighting fixture arranged corresponding to each concave surface B, and this lighting fixture 3 is located below the center of the concave surface B and is supported by three pipes 5. ing. Further, the base end side of the pipe 5 is attached to a pipe body 6 disposed on the downward protrusion 4 of the ceiling main body A (see Figs. 6 to 8).
(see figure). Note that an electric wire for supplying electricity to the lighting fixture 3 is inserted through the pipe 5. As shown in FIGS. 3 to 5, the lighting fixture 3 is provided with a plurality of stepped portions 8 extending in the circumferential direction around the frame 7 in the vertical direction. The light from the lamp 9 hits the entire outer periphery of the frame 7 and can illuminate the U-shaped glass body 10 suspended on the outside of the frame 7 from the inside without any corner. Further, a reflector plate 11 having a hemispherical concave curved surface is provided at the center of the lower part of the frame body 7, and a lamp 12 that directly illuminates the room is provided at the center of the reflector plate 11.

Further, in each lighting fixture 3, the light amount of the white lamp 14 and the colored lamps 15A, 15B, and 15C is individually adjusted by the control device. The reason why the white lamp 14 is provided is that white light can theoretically be obtained by simply superimposing the three primary colors of light, but in reality, due to current fluctuations, manufacturing errors between lamps, etc. This is because it is difficult to obtain white light just by overlapping them.

The pipe body 6 is supported by the building frame via a support member (not shown) such as a hanging bolt,
In addition to the function of supporting the lighting fixture 3, it also has the function of supporting various equipment. That is, in FIG. 2, ◎ represents the lighting fixture 3, ○ represents the air conditioning outlet or inlet 21, sprinkler 22, and smoke detector 23. These devices are shown in FIGS. 6 to 8. As shown, it is attached to the tube body 6 using attachment members such as bolts, and is arranged in a well-balanced manner at a predetermined position on the ceiling surface. Further, 24 in FIG. 2 is a suspension body on which the name of the ceremony, etc. is drawn, and this suspension body 24 is suspended by a rope passing through the tube body 6.

Next, the operation of the above lighting device will be explained.

(i) When illuminating the entire ceiling in white, the control device lights up the partition plate 1 for all lighting fixtures 3.
Among the lamps arranged above 3, white lamp 14
While energizing only the colored lamps 15, the other colored lamps 15
An operation is performed to stop the power supply to A, 15B, and 15C. As a result, all of the concave surfaces B can be illuminated in white, and by extension, the entire ceiling can be illuminated in white.

(ii) When illuminating the entire ceiling with any one of the three primary colors of red, blue, and green, the control device energizes only the colored lamps of the desired hue for all lighting fixtures 3, and also energizes the other colored lamps. perform an operation to stop the energization. Thereby, all of the concave surfaces B can be illuminated with any one of the three primary colors.

(iii) When illuminating the entire ceiling with an arbitrary neutral color different from the three primary colors, each lighting fixture 3
For all, each colored lamp 15A, 15
The adjustment operation of the current supplied to B and 15C is similarly performed. As a result, each colored lamp 15
The light amounts of A, 15B, and 15C are adjusted, and the light emitted from each colored lamp 15A, 15B, and 15C is superimposed on each other and irradiated onto the concave surface B.
All of the concave surfaces B can be illuminated with the same arbitrary neutral color.

(iv) When each of the concave curves B arranged in a honeycomb shape is individually illuminated in a desired color to draw a single image on the entire ceiling, the control device controls the white lamp 14 and each Adjustment of the current supplied to the colored lamps 15A, 15B, and 15C is performed individually. As a result, for each lighting fixture 3, the white lamp 14 and each colored lamp 15A, 15B, 1

Further, in the above embodiment, three types of colored lamps 15A, 15B, and 15C are arranged in addition to the white lamp 14 as concave B irradiation lamps, but only the white lamp 14 or only one of the colored lamps is arranged. However, a configuration may be adopted in which the amount of light is adjusted.

Further, in the above embodiment, an example in which the present invention is applied to the ceiling of a hotel banquet hall is described, but the present invention is not limited to this, and can be applied to the ceiling of other rooms such as a conference hall or an entrance hall. Of course, it can also be applied to walls.

In addition, this device allows each lighting fixture 3 to
It can also be used as an image forming device, such as a television, by changing it every moment using a control device using a computer.

[Effects of the Invention] As explained above, according to the present invention, a ceiling surface or a wall surface is composed of a plurality of continuous exposed concave surfaces, and a large number of such ceiling surfaces or the same parts are continuously exposed. Since they are obtained by arranging them side by side, manufacturing and assembly are easy, and after assembly, the entire ceiling surface is under the same conditions, making it easy to manage the strength.

In addition, a light source is provided at a position facing the concave surface, and the light source is composed of a plurality of lamps that emit each of the three primary colors of blue, red, and green, and the current supplied to the lamps is adjusted by a control device. Therefore, the individual concave surfaces can be illuminated with any color (including not only the three primary colors but also intermediate colors) and any illuminance.

Since each concave surface can be illuminated with any color and illuminance, the entire ceiling or wall surface can be illuminated with any color and illuminance, and the concave surfaces can be used to create patterns. It is also possible to gradually change the color, illuminance, and pattern. As a result, even when a venue is used for multiple purposes, the ceiling or wall surface can be varied in various ways to adapt to the atmosphere of the venue, and it is particularly suitable for installation in a convention hall. It has the following effects.
