{Embodiment}
<Overall description>
The display device according to the embodiment will be described below. FIG. 1 is a front view showing an exhibition device 10. FIG. FIG. 2 is a plan view showing the display device 10. As shown in FIG. FIG. 3 is a cross-sectional view taken along line III--III of FIG. FIG. 4 is an enlarged view of FIG. FIG. 5 is a partial cross-sectional view taken along line VV of FIG.

The display device 10 is, for example, a device used for displaying exhibits in an art gallery or museum. The exhibition device 10 includes a main body 20 and a lighting device 60 . An exhibit is displayed in the main body 20, and the illumination device 60 illuminates the exhibit.

<About the main unit>
The main body 20 has a ceiling panel 50 covering the upper side of the exhibition space 20S. In this embodiment, the main body 20 is formed in the shape of a case that forms an exhibition space 20S inside. More specifically, body 20 has a lower base 22 , four transparent side panels 24 and a ceiling panel 50 .

In this embodiment, the lower base 22 is formed in a rectangular plate shape. The lower base 22 may be placed directly on the installation surface. A plurality of legs that partially protrude from the lower surface of the lower base 22 may protrude, and the lower base 22 may be placed on the installation surface via the legs. Casters may be provided on the lower base 22, and the lower base 22 may be placed on the installation surface via the casters. When the exhibition apparatus 10 is installed indoors, the installation surface is the floor of the exhibition room. When the display device 10 is installed outdoors, the installation surface may be the ground.

The four transparent side panels 24 are made of transparent rectangular plates. The transparent side panel 24 is made of, for example, a glass-based plate material. The glass may be silicate glass containing silicate as a main component, or resin glass such as acrylic glass. Silicate glass is more transparent than resin glass, and the surface smoothness is excellent, so that the presence of the transparent side panel 24 can be made thinner. The transparent side panel 24 may be single glazing or double glazing.

Four transparent side panels 24 are supported so as to rise from the four peripheral sides of the lower base 22 . As a result, an exhibition space 20S surrounded by four transparent side panels 24 is formed above the lower base 22. As shown in FIG.

Both side end surfaces of the four transparent side panels 24 may be cut obliquely. A gap is provided between the oblique end surfaces of the side portions of the adjacent transparent side panels 24, and the gap may be filled with a glass sealing agent such as silicone. The oblique end surfaces of the sides of the adjacent transparent side panels 24 may be in contact with each other.

The upper edge portions of the four transparent side panels 24 are held by a frame member 30 so as to maintain a rectangular positional relationship. The frame member 30 forms a square frame when viewed as a whole. In this embodiment, the main frame member 30 also serves to support the ceiling panel 50 .

The frame member 30 includes four frames 32 corresponding to the four transparent side panels 24, respectively. The frame member 30 is configured by connecting the four frames 32 so as to form a square frame.

The frame 32 is made of metal such as aluminum, for example. The frame 32 may be made of resin. The frame 32 is formed in an elongated shape extending along the upper edge of the transparent side panel 24 . The frame 32 has a frame body portion 33, side panel pressing pieces 34, and a pair of ceiling panel supporting pieces 35 (see FIG. 5). The frame body portion 33 has a quadrangular prism shape. The vertical dimension of the frame main body 33 is larger than the thickness of the ceiling panel 50 .

The side panel pressing piece 34 is formed in a long rectangular plate shape along the longitudinal direction of the frame body portion 33 . The side panel pressing piece 34 extends outward in the horizontal direction from the upper edge of the surface of the frame body portion 33 facing the outside of the body 20 . The projection dimension of the side panel pressing piece 34 from the frame body portion 33 is larger than the thickness dimension of the transparent side panel 24 . Further, the side panel pressing piece 34 has a convex portion 34p at a position separated from the frame main body portion 33 by the thickness dimension of the transparent side panel 24. As shown in FIG. The convex portion 34p is a portion that protrudes downward from the tip edge of the side panel pressing piece 34. As shown in FIG.

A side panel holding groove 36 is formed by the outward surface of the frame body portion 33, the downward surface of the side panel pressing piece 34, and the inward surface of the protrusion 34p. The upper edge of the transparent side panel 24 is sandwiched between the outward surface of the frame main body 33 and the inward surface of the projection 34p, and the upward surface of the transparent side panel 24 is sandwiched between the side panels. The upper edge of the transparent side panel 24 is fitted into the side panel holding groove 36 by being arranged to face the downward surface of the pressing piece 34 . As a result, the upper edge of the transparent side panel 24 is kept at a fixed position with respect to the frame 32 in its thickness direction. A glass sealing agent such as silicone may be filled between the upper edge of the transparent side panel 24 and the side panel holding groove 36 in the fitted state.

The pair of ceiling panel support pieces 35 are formed in a long rectangular plate shape along the longitudinal direction of the frame main body portion 33 . The pair of ceiling panel support pieces 35 extend outward in the horizontal direction from the upper edge and the lower edge of the surface of the frame main body 33 facing the inside of the main body 20 .

A ceiling panel holding groove 37 is formed by the inward surface of the main body 20 of the frame main body portion 33 and the surfaces of the pair of ceiling panel support pieces 35 facing each other. The upper edge of the transparent side panel 24 is sandwiched between the outward surface of the frame main body 33 and the inward surface of the projection 34p, and the upward surface of the transparent side panel 24 is sandwiched between the side panels. The upper edge of the transparent side panel 24 is fitted into the ceiling panel holding groove 37 by being arranged to face the downward surface of the pressing piece 34 . As a result, the edge of one of the sides of the ceiling panel 50 is kept at a fixed position with respect to the frame 32 in the vertical direction. In the fitted state, a glass sealant such as silicone may be filled between the edge of the ceiling panel 50 and the ceiling panel holding groove 37 .

Frame 32 as described above may be formed by extrusion of aluminum.

The configuration for keeping the four frames 32 in the shape of a square frame is arbitrary. For example, the four frames 32 may be connected in a square frame shape by screwing, or may be connected in a square frame shape by welding or adhesive.

In this embodiment, the four frames 32 are connected in the form of a square frame by means of a screwed structure using an L-shaped connecting member 38 . That is, the connecting member 38 is formed in an L-shaped plate made of metal or the like. Each end face of the frame 32 is cut so as to form an angle of 45 with respect to the longitudinal direction of the frame 32, and the four frames 32 can be arranged in the shape of a square frame with the end faces facing each other. One of the straight plate-shaped portions of the connecting member 38 is placed on the upper side of one end of the adjacent frame 32 , and the other straight plate-shaped portion of the connecting member 38 is placed on the other end of the adjacent frame 32 . It is placed on the upper side of the part (see FIG. 4). In this state, each straight portion is fixed by screws S to the ends of the frame 32 . As a result, the adjacent frames 32 are kept connected in an L-shape. Adjacent ends of the four frames 32 are similarly connected by connecting members 38, thereby connecting the four frames 32 so as to form a square frame shape.

By connecting the four frames 32 in the form of a square frame, the upper edges of the four transparent side panels 24 are also maintained in a square positional relationship.

Supporting the lower edges of the four transparent side panels 24 on the lower base 22 may be the same as the configuration using the frame member 30 described above.

In this embodiment, the main body 20 has a stand 40 on which an exhibit can be placed. The table 40 has a mounting plate 42 above the lower base 22 . In this embodiment, the table 40 is formed in a rectangular parallelepiped shape having four side plates 43 and a mounting plate 42 . The four side plates 43 are assembled with screws, an adhesive, or the like so as to form a square in plan view. The mounting plate 42 is fixed to the upper portions of the four side plates 43 with screws, an adhesive, or the like, and is supported in a horizontal position separated upward from the lower portions of the side plates 43 . By placing or fixing the stand 40 on the upper surface of the lower base 22, the placing plate 42 is arranged at a height suitable for display from the installation surface.

Since the four transparent side panels 24 exist above the mounting plate 42 of the stand 40, the display space 20S above the stand 40 is partitioned from the outside by the four transparent side panels 24. As shown in FIG.

The configuration for supporting the mounting plate 42 is not limited to the above example. The mounting plate may be supported at a position above the lower base 22 by one or more legs. The mounting plate may be supported at a height position away from the installation surface by the transparent side panel 24 . The mounting plate may be suspended from the ceiling panel 50 and supported at a height position away from the installation surface.

Note that the transparent side panel 24 may be erected upward from the top of the base 40 instead of the lower base 22 .

<About the lighting device>
The illumination device 60 is a device that illuminates the exhibition space 20S with illumination light. The illumination device 60 is preferably a flat illumination device. For example, the lighting device 60 may be a lighting device thinner than the thickness of the ceiling panel 50, for example, a lighting device with a thickness of 2 mm or less. Moreover, it is preferable that the illumination device 60 is a surface-emitting light source.

The planar lighting device 60 that emits surface light may be, for example, an organic EL lighting device. An organic EL (electro-luminescence) lighting device is a lighting device in which a light-emitting layer made of an organic compound is sandwiched between an electrode and a transparent electrode. By applying a voltage to the light-emitting layer through the electrode and the transparent electrode, the light-emitting layer emits light over the entire surface. As a result, wide light distribution with little unevenness can be obtained on the entire light emitting surface. By irradiating the exhibit with such light, it is possible to softly illuminate the entire exhibit while suppressing dark shadows. In addition, the light emitted by the organic EL lighting device has a visible light frequency component that spreads widely like natural light. Therefore, the color reproducibility of the exhibit illuminated by the light emitted by the organic EL lighting device is enhanced. In addition, since the light emitted by the organic EL lighting device contains little or no ultraviolet rays and infrared rays, deterioration of the exhibits is suppressed.

Note that it is not essential that the planar lighting device 60 that emits surface light is an organic EL lighting device. The flat lighting device 60 that emits surface light may be, for example, the lighting device 60 in which the light emitted from the light-emitting diode is diffused by a diffusion plate.

It is not essential that the lighting device 60 be a flat lighting device that emits surface light. The lighting device 60 may be a lighting device having light emitting diodes, fluorescent lamps, or incandescent lamps.

In the present embodiment, description is made on the assumption that the illumination device 60 is a rectangular organic EL illumination device. Also, in this embodiment, an example in which the exhibition apparatus 10 includes a plurality of (here, four) illumination devices 60 will be described. The lighting device 60 may be one.

<Regarding the ceiling panel and the manner in which the lighting device is attached to the ceiling panel>
As described above, the ceiling panel 50 covers the upper side of the exhibition space 20S. In this embodiment, the ceiling panel 50 is formed in a rectangular plate shape. The ceiling panel 50 is supported at a predetermined height position by fitting and holding the edges of the four sides of the ceiling panel 50 in the ceiling panel holding grooves 37 of the frame 32 . The height position of the ceiling panel 50 is arbitrary. The ceiling panel 50 may be positioned, for example, at a height of 2 m or more from the installation surface of the lighting device 60 .

The ceiling panel 50 has a first area E1 and a second area E2. The first area E1 and the second area E2 are exclusive areas. The illumination device 60 is attached to the first area E1. Here, the illumination device 60 is attached so as to spread over the entire first area E1. The ceiling panel 50 has specular reflectivity with respect to the exhibition space 20S in the second area E2. Therefore, when the ceiling panel 50 is observed from the exhibition space 20S, either the area where the light emitting surface of the lighting device 60 spreads or the area having specular reflectivity is observed.

More specifically, the ceiling panel 50 has a plurality of first regions E1. In this embodiment, four first areas E1 are provided in the central area away from the four sides of the ceiling panel 50. As shown in FIG. The four first areas E1 are rectangular areas of the same size. The four first regions E1 are arranged in two columns and two rows in the direction of two orthogonal sides of the ceiling panel 50 . A gap is provided between the adjacent first regions E1 in each direction of two orthogonal sides of the ceiling panel 50 .

The second area E2 is located in the area surrounding the four first areas E1 of the ceiling panel 50 and the area between the four first areas E1. Therefore, the second regions E2 are spaced apart from the plurality of first regions E1.

A lighting device 60 is attached to each of the four first regions E1. The illumination device 60 is formed in a rectangular flat shape that spreads with the same size and shape as the first region E1. The light emitting surface of the illumination device 60 also has the same size and shape as the first region E1.

The ceiling panel 50 as described above can be realized by, for example, a configuration including a transparent panel 51 and a specular reflection layer 52 .

The transparent panel 51 is made of a transparent rectangular plate. The transparent panel 51 is made of, for example, a glass-based plate material. The glass may be silicate glass containing silicate as a main component, or resin glass such as acrylic glass. Silicate glass is more transparent than resin glass, and the surface smoothness is excellent, so that the presence of the transparent panel 51 can be made thinner. The transparent panel 51 may be a single layer glass or a double layer glass. The transparent panel 51 may have a thickness of 10 mm or less, for example.

The specular reflection layer 52 is located on the main surface of the transparent panel 51 . Here, the specular reflection layer 52 positioned on the main surface of the transparent panel 51 means that the specular reflection layer 52 is positioned so as to be in contact with the upper surface or the lower surface of the transparent panel 51 . In this embodiment, the specular reflection layer 52 is located in the second region E2 of one of the main surfaces of the transparent panel 51. As shown in FIG. The specular reflection layer 52 has specular reflectivity at least toward the exhibition space 20S side. Therefore, when the second area E2 of the transparent panel 51 is viewed from the exhibition space 20S side, a mirror surface is observed. When the first region E1 of the transparent panel 51 is viewed from the exhibition space 20S without the illumination device 60, the upper side can be seen through (see FIG. 3).

The specular reflection layer 52 may be formed, for example, by attaching a mirror film to the upper major surface of the transparent panel 51 opposite to the exhibition space 20S. A mirror film is, for example, a resin film on which a reflective film made of metal is formed by vapor deposition or sputtering. A mirror reflection layer 52 is formed on the upper main surface of the transparent panel 51 by adhering or adhering the reflective surface of the mirror film to the upper main surface of the transparent panel 51 .

It is not essential that the specular reflection layer 52 is formed of a mirror film. The upper main surface of the transparent panel 51 may be directly silver-plated, the upper main surface of the transparent panel 51 may be mirror-coated, or the upper surface of the transparent panel 51 may be a mirror-finished metal plate. may be superimposed.

It is not essential that the specular reflection layer 52 is positioned on the upper surface of the transparent panel 51, and the specular reflection layer 52 is provided on the lower surface of the transparent panel 51 so as to have specular reflectivity when viewed from the exhibition space 20S side. may be located.

A lighting device 60 is attached to the ceiling panel 50 so that the light emitting surface faces the exhibition space 20S. The mounting structure of the lighting device 60 to the ceiling panel 50 is arbitrary.

L-shaped positioning and fixing portions 56 are fixed to four corners of the first region E1 on the upper surface of the ceiling panel 50 by welding, screwing, adhesive, or the like. Then, the illumination device 60 is placed on the first region E1 of the ceiling panel 50 with the four corners of the lighting device 60 being positioned by the positioning fixing portions 56 . Thereby, the lighting device 60 is attached to the first region E1 of the ceiling panel 50. As shown in FIG.

The mounting structure of the lighting device 60 to the ceiling panel 50 is not limited to the above example, and any structure may be employed as long as the lighting device 60 can be kept at a fixed position with respect to the ceiling panel 50 . For example, the lighting device 60 may be fixed to the ceiling panel 50 by screwing.

The lighting device 60 is attached to the first area E1 of the top surface of the ceiling panel 50, and the specular reflection layer 52 is provided to the second area E2 of the top surface. The light is irradiated to the exhibition space 20S without being reflected.

<About spot lighting>
The exhibition device 10 includes a spot lighting device 70 . The spot lighting device 70 is a device that irradiates downward spot light into the exhibition space 20S. The spot light is light that is irradiated to a range narrower than the irradiation range of the illumination device 60 . The spot lighting device 70 can brightly illuminate a limited range in the exhibition space 20S.

The spot lighting device 70 may be any lighting device that irradiates light in a more limited range than the lighting device 60 described above. The light source of the spot lighting device 70 may be, for example, an organic EL light-emitting element, a light-emitting diode, a fluorescent lamp, an incandescent lamp, or the like. In order to restrict the emitted light to a certain range, it may depend on the light distribution characteristics of the light source, or at least one of a reflecting mirror and a lens may be used.

The spot lighting device 70 is supported in a suspended state from the frame member 30 . In this embodiment, four spot lighting devices 70 are supported in a state of being suspended from each corner of the frame member 30 . The spot lighting device 70 is fixed to the frame member 30 by screws, adhesive, or the like. The spot lighting device 70 may be fixed to the ceiling panel 50 or may be fixed to the transparent side panel 24 .

The illumination light from the four spot illumination devices 70 is, for example, above the table 40 in the exhibition space 20S and is illuminated toward the central area of the table 40 in a plan view.

The position and number of spot illumination devices 70 are arbitrary. For example, one or a plurality of spot lighting devices 70 may be provided, or five or more may be provided. Also, for example, the spot lighting device 70 may be fixed to the longitudinal middle portion of the frame 32 . The spot illumination device 70 may be omitted.

In this exhibition apparatus, a lighting device that emits light upward, for example, a lighting device that emits light toward the ceiling panel 50 may be omitted.

<About wiring example>
A layout example of the wirings 64a and 64b of the lighting device 60 will be described. Wirings 64 a and 64 b extend from the illumination device 60 . The wirings 64a and 64b are, for example, electric wires for power supply. The wirings 64a and 64b may include signal lines.

The lighting device 60 is arranged in the first area E1, and the wires 64a and 64b are arranged on the upper surface of the ceiling panel 50 so as to pass through the second area. In this embodiment, wiring 64a extends from one lighting device 60 toward an external power source. The wiring 64a extends across the second area E2 on the upper side of the ceiling panel 50. As shown in FIG. The wiring 64b extends so as to connect the four lighting devices 60 in sequence. The wiring 64b also extends across the second area E2 on the upper side of the ceiling panel 50. As shown in FIG. Electric power is supplied to each of the plurality of lighting devices 60 by the wirings 64a and 64b so that they can be driven to emit light.

On the upper side of the ceiling panel 50, the wires 64a, 64b are positioned above the specular reflection layer 52. FIG. Therefore, even when the ceiling panel 50 is viewed from the exhibition space 20S, the wires 64a and 64b are hidden by the specular reflection layer 52 of the second area E2.

Since the spot lighting device 70 is positioned within the exhibition space 20S, the spot lighting wiring 74 of the spot lighting device 70 is pulled out from the exhibition space 20S. The spot lighting wiring 74 may be led out to the outside at any location of the ceiling panel 50 , the frame member 30 , or the transparent side panel 24 .

In the present embodiment, a lead-out hole 30h is formed in the connecting portion of the frame member 30 with the frame 32 (see FIG. 4). The extraction hole 30 h may be formed at the boundary between the adjacent transparent side panels 24 . For example, a glass sealant 28 is filled between the side surfaces of the adjacent transparent side panels 24 . The extraction hole 30h is set in a region above the glass sealant 28 so as to overlap with the glass sealant. A spot illumination wiring 74 extending from the spot illumination device 70 supported at the corner of the frame 32 passes through the glass sealant 28 between the side surfaces of the adjacent transparent side panels 24 and is led to the extraction hole 30h. , is pulled out of the display device 10 through the pull-out hole 30h. The spot lighting wiring 74 drawn out from each spot lighting device 70 is drawn out along the frame member 30 or through the ceiling panel 50 toward the power source.

<Installation example of the exhibition device 10>
FIG. 6 is an explanatory diagram showing an installation example of the display device 10 in the exhibition room. The display device 10 is placed on the floor 100, which is the installation surface. The height H of the display device 10 is set to 2 m or more from the floor 100, for example. A ceiling lighting device 120 for the exhibition room is provided on the ceiling 110 .

An exhibit 130 is exhibited on the upper side of the platform 40 of the exhibit apparatus 10 . The illumination light of the illumination device 60 illuminates the exhibit 130 downward from the ceiling panel 50 . The spot light from the spot lighting device 70 is also directed toward the exhibit 130 .

An observer P having a standard height observes the exhibit 130 . The line of sight of the observer P is directed to the exhibit 130 . There is a possibility that the ceiling panel 50 will enter the observer's P peripheral visual field.

However, since lighting device 60 is a surface light source, it is difficult to feel glare. In addition, the scenery below the ceiling panel 50 is reflected in the second area E2 which is not the light source. For this reason, the ceiling panel 50 is visually recognized as blending into the surrounding scenery, and the ceiling panel 50 becomes inconspicuous. In addition, a portion of the exhibit 130 that is not visible to the observer P can be observed through the mirror surface in the second area E2 of the ceiling panel 50 .

Also, the lower surface of the ceiling panel 50 is a surface formed by the transparent panel 51 . Therefore, the lower surface of the ceiling panel 50 seen by the observer P can be observed as a smooth and clean surface.

Moreover, since the specular reflection layer 52 is observed through the transparent panel 51, it can be observed as a ceiling with a sense of depth.

Moreover, even if the ceiling lighting device 120 on the ceiling 110 is in the peripheral vision, it can be hidden by the ceiling panel 50 . Therefore, the light L from the ceiling lighting device 120 is blocked by the ceiling panel 50 and is difficult for the observer P to directly observe. This suppresses glare caused by the presence of the ceiling lighting device 120 in the peripheral vision when observing the exhibit 130 in the exhibit apparatus 10 . In addition, since the light L of the ceiling lighting device 120 is blocked by the ceiling panel 50, the illumination light from the lighting device 60 is mainly exhibited on the exhibit 130, and the spot lighting light from the spot lighting device 70, if present. Object 130 is irradiated. Therefore, the lighting effect of the exhibition device 10 is effectively exhibited.

<Effects, etc.>
According to the exhibition apparatus 10 configured as described above, the illumination device 60 is arranged in the first area E1 of the ceiling panel 50, and illumination light from the illumination device 60 is applied. A peripheral area of the exhibition space 20S is reflected in the second area E2 of the ceiling panel 50. As shown in FIG. For this reason, the ceiling panel 50 is less likely to be observed by the observer P as a light shield, and the presence of the exhibition apparatus 10 can be reduced. This makes it easier for the observer P to observe the exhibit 130 intensively, and the exhibit 130 suitable for viewing the exhibit 130 can be provided.

Moreover, since the wirings 64a and 64b extending from the lighting device 60 extend via the second region E2, the wirings 64a and 64b can be made inconspicuous. This also makes it easier for the observer P to concentrate and observe the exhibit 130 .

In addition, the ceiling panel 50 is provided with a plurality of first regions E1 separated from each other, and the illumination device 60 is attached to each of the first regions E1. Therefore, the exhibit 130 can be illuminated from the other direction by each of the plurality of lighting devices 60 spaced apart from each other. As a result, shadows on the exhibit 130 can be reduced, making it easier to observe the exhibit 130 .

Also, the ceiling panel 50 has a transparent panel 51 made of glass-based plate material and a specular reflection layer 52 positioned on the main surface of the transparent panel 51 . By using the transparent panel 51 which is a glass-based plate material for the ceiling panel 50, the thickness of the ceiling panel 50 can be made difficult to perceive.

Also, the specular reflection layer 52 is provided on the surface opposite to the exhibition space 20S. Therefore, the specular reflection layer 52 is observed through the transparent panel 51, which is a glass-based plate material, as viewed by the observer P observing the inside of the exhibition space 20S. It is easy to increase the smoothness of the surface of the transparent panel 51, which is a glass-based plate material. In addition, since the observer P observes the background reflected in the mirror reflection layer 52 on the far side of the transparent panel 51, the observer P can observe the background with a sense of depth. Thereby, the ceiling panel 50 can be made to look beautiful.

Moreover, if the lighting device 60 is an organic EL lighting device, the thickness can be reduced, and the lighting device 60 attached to the ceiling panel 50 can be made inconspicuous.

The main body 20 also has a stand 40 on which the exhibit 130 can be placed, and four transparent panels 51 that divide the four sides of the exhibition space 20S on the stand 40 . Therefore, the exhibit 130 in the exhibit space 20S can be observed from four directions through the four transparent side panels 24 .

In addition, while the exhibition space 20S is a space partitioned by the transparent panel 51 and the ceiling panel 50, the presence of each partition can be minimized. This allows the observer P to concentrate on the exhibit 130 .

In addition, if the ceiling panel 50 is positioned at a height of 2 m or more from the installation surface, the ceiling lighting device 120 of the exhibition room can be used when an observer P of standard height sees the exhibit 130 in the exhibition space 20S. It is easily hidden by the ceiling panel 50.

In addition, by providing the display device 10 with the spot lighting device 70, it is possible to brightly illuminate a partial portion of the exhibit 130. FIG. By pulling out the spot lighting wiring 74 extending from the spot lighting device 70 above the upper surface of the ceiling panel 50 , the spot lighting wiring 74 can be hidden by the ceiling panel 50 . For example, even if the spot lighting wiring 74 extends along the frame member 30 , the spot lighting wiring is hidden by the ceiling panel 50 when viewed obliquely downward from the ceiling panel 50 . Therefore, the wiring 74 for spot lighting can also be made inconspicuous by the ceiling panel 50. - 特許庁

{Modification}
It is not essential that there are four transparent side panels 24 as in this embodiment. Some of the four transparent side panels 24 may be omitted.
