[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-094446 Summary of the Invention [Problem to be solved by the invention]

[0004] Display cases are used for viewing the exhibits, so it is desirable to minimize the presence of the display cases themselves.

[0005] Therefore, an object of the present disclosure is to provide an exhibition device that reduces the presence of the exhibition device and is therefore suitable for viewing exhibits. [Means for solving the problem]

[0006] In order to solve the above problem, the exhibition device comprises a main body having a ceiling panel that covers the upper side of the exhibition space, and a lighting device that irradiates illumination light into the exhibition space, wherein the ceiling panel has a first area and a second area, the lighting device is attached to the first area, and the ceiling panel has specular reflectivity with respect to the exhibition space in the second area. [Effects of the Invention]

[0007] With this exhibition device, the surrounding area of ​​the exhibition space is reflected in the second area of ​​the ceiling panel. This makes it difficult for the ceiling panel to be seen as a light blocker, and the presence of the exhibition device can be reduced. This makes it possible to provide an exhibition device that is suitable for viewing exhibits. [Brief explanation of the drawings]

[0009] {Embodiment} <Overall explanation> The exhibition device according to the embodiment will be described below. Fig. 1 is a front view of the exhibition device 10. Fig. 2 is a plan view of the exhibition device 10. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1. Fig. 4 is an enlarged view of Fig. 2. Fig. 5 is a partial cross-sectional view taken along line VV in Fig. 2.

[0010] The exhibition device 10 is a device used to display exhibits in, for example, an art gallery or a museum. The exhibition device 10 includes a main body 20 and a lighting device 60. An exhibit is displayed inside the main body 20, and the lighting device 60 illuminates the exhibit.

[0011] <About the device> The main body 20 has a ceiling panel 50 that covers the upper side of the exhibition space 20S. In this embodiment, the main body 20 is formed in the shape of a case that defines the exhibition space 20S inside. More specifically, the main body 20 has a lower base 22, four transparent side panels 24, and the ceiling panel 50.

[0012] In this embodiment, the lower base 22 is formed in the shape of a rectangular plate. The lower base 22 may be placed directly on the installation surface. The lower surface of the lower base 22 may have a plurality of legs that protrude partially, and the lower base 22 may be placed on the installation surface via the legs. The lower base 22 may be provided with casters, and the lower base 22 may be placed on the installation surface via the casters. When the exhibition device 10 is installed indoors, the installation surface is the floor of the exhibition room. When the exhibition device 10 is installed outdoors, the installation surface may be the ground.

[0013] The four transparent side panels 24 are formed from transparent rectangular plates. The transparent side panels 24 are formed from, for example, glass-based plates. The glass may be silicate glass, which is primarily composed of silicate, or resin glass such as acrylic glass. Using silicate glass rather than resin glass can increase transparency and provide excellent surface smoothness, making the transparent side panels 24 less noticeable. The transparent side panels 24 may be single-pane glass or double-pane glass.

[0014] The four transparent side panels 24 are supported so as to stand upright from the four peripheral sides of the lower base 22. As a result, an exhibition space 20S surrounded by the four transparent side panels 24 is formed above the lower base 22.

[0015] Both side end faces of the four transparent side panels 24 may be cut at an angle. A gap may be provided between the oblique side end faces of adjacent transparent side panels 24, and this gap may be filled with a glass sealant such as silicone. The oblique side end faces of adjacent transparent side panels 24 may be in contact with each other.

[0016] The upper edges of the four transparent side panels 24 are held in a rectangular positional relationship by the frame member 30. The frame member 30 forms a rectangular frame when viewed as a whole. In this embodiment, the frame member 30 also serves to support the ceiling panel 50.

[0017] The frame member 30 includes four frames 32 corresponding to the four transparent side panels 24. The frame member 30 is configured by connecting the four frames 32 to form a square frame.

[0018] The frame 32 is made of a metal such as aluminum. The frame 32 may also 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 main body 33, a side panel pressing piece 34, and a pair of ceiling panel support pieces 35 (see FIG. 5). The frame main body 33 is in the shape of a quadrangular prism. The dimension of the frame main body 33 in the vertical direction is greater than the thickness of the ceiling panel 50.

[0019] The side panel pressing piece 34 is formed in the shape of a long rectangular plate extending along the longitudinal direction of the frame main body 33. The side panel pressing piece 34 extends outward in the horizontal direction from the upper edge of the surface of the frame main body 33 facing outward from the main body 20. The projection of the side panel pressing piece 34 from the frame main body 33 is greater than the thickness of the transparent side panel 24. The side panel pressing piece 34 also has a protrusion 34p at a position spaced apart from the frame main body 33 by the thickness of the transparent side panel 24. The protrusion 34p is a portion that protrudes downward from the tip edge of the side panel pressing piece 34.

[0020] The outward surface of the frame main body 33, the downward surface of the side panel pressing piece 34, and the inward surface of the protrusion 34p form a side panel holding groove 36. 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 protrusion 34p, and the upward surface of the transparent side panel 24 is positioned opposite the downward surface of the side panel pressing piece 34, so that the upper edge of the transparent side panel 24 is fitted into the side panel holding groove 36. This holds the upper edge of the transparent side panel 24 at a fixed position in the thickness direction relative to the frame 32. In the fitted state, a glass sealant such as silicone may be filled between the upper edge of the transparent side panel 24 and the side panel holding groove 36.

[0021] The pair of ceiling panel support pieces 35 are formed in the shape of long rectangular plates extending along the longitudinal direction of the frame main body 33. The pair of ceiling panel support pieces 35 extend outward in the horizontal direction from the upper and lower edges of the surface of the frame main body 33 facing inward of the main body 20.

[0022] A ceiling panel holding groove 37 is formed by the inward surface of the main body 20 of the frame main body 33 and the opposing surfaces of the pair of ceiling panel support pieces 35. 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 protrusion 34p, and the upward surface of the transparent side panel 24 is positioned opposite the downward surface of the side panel pressing piece 34, so that the upper edge of the transparent side panel 24 is fitted into the ceiling panel holding groove 37. This keeps the edge of one side of the ceiling panel 50 in a fixed position in the up-down direction relative to the frame 32. 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.

[0023] The frame 32 as described above may be formed by extrusion of aluminum.

[0024] The four frames 32 may be connected to each other in a rectangular frame shape by any suitable configuration. For example, the four frames 32 may be connected to each other in a rectangular frame shape by screws, welding, or adhesive.

[0025] In this embodiment, four frames 32 are connected to each other in a rectangular frame shape using an L-shaped connecting member 38 and a screw configuration. That is, the connecting member 38 is formed in an L-shaped plate shape from metal or the like. Each end face of the frame 32 is cut at a 45° angle with respect to the longitudinal direction of the frame 32, and the four frames 32 are arranged in a rectangular frame shape with their end faces butted together. One straight plate-shaped portion of the connecting member 38 is placed on top of one end of an adjacent frame 32, and the other straight plate-shaped portion of the connecting member 38 is placed on top of the other end of the adjacent frame 32 (see FIG. 4). In this state, each straight portion is fixed to the end of the frame 32 with a screw S. This maintains the adjacent frames 32 connected to each other in an L-shape. Adjacent ends of the four frames 32 are similarly connected by the connecting member 38, so that the four frames 32 are connected to form a rectangular frame shape.

[0026] By connecting the four frames 32 in a rectangular frame shape, the upper edges of the four transparent side panels 24 are also kept in a rectangular positional relationship.

[0027] The lower edge portions of the four transparent side panels 24 may also be supported by the lower base 22 using the same structure as that using the frame member 30 described above.

[0028] In this embodiment, the main body 20 is provided with a platform 40 on which an exhibit can be placed. The platform 40 has a mounting plate 42 that is higher than the lower base 22. In this embodiment, the platform 40 is formed in the shape of a rectangular parallelepiped having four side plates 43 and the mounting plate 42. The four side plates 43 are assembled with screws, adhesive, etc. so as to form a square in a plan view. The mounting plate 42 is fixed to the upper parts of the four side plates 43 with screws, adhesive, etc., and is supported in a horizontal position spaced above and spaced apart from the lower parts of the side plates 43. By placing or fixing this platform 40 on the upper surface of the lower base 22, the mounting plate 42 is positioned at a height above the installation surface that is suitable for display.

[0029] Since there are four transparent side panels 24 above the mounting plate 42 of the stand 40, the four transparent side panels 24 separate the exhibition space 20S above the stand 40 from the outside on all four sides.

[0030] 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.

[0031] The transparent side panel 24 may be provided standing upward from the upper part of the platform 40 instead of being attached to the lower base 22 .

[0032] <About the lighting equipment> The lighting device 60 is a device that irradiates illumination light into the exhibition space 20S. The lighting device 60 is preferably a flat lighting device. For example, the lighting device 60 may be thinner than the thickness of the ceiling panel 50, for example, a lighting device with a thickness of 2 mm or less. Furthermore, the lighting device 60 is preferably a surface-emitting light source.

[0033] The flat, surface-emitting lighting device 60 may be, for example, an organic electroluminescence (EL) lighting device. An organic electroluminescence (EL) 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 via the electrode and the transparent electrode, the light-emitting layer emits light across the entire surface. This results in light with little unevenness and a wide light distribution across the entire light-emitting surface. By irradiating such light onto an exhibit, the entire exhibit can be softly illuminated while suppressing dark shadows. Furthermore, the light emitted by an EL lighting device has a wide range of visible light frequency components, similar to natural light. This improves the color reproducibility of exhibits illuminated by the light emitted by the EL lighting device. Furthermore, the light emitted by an EL lighting device contains little or no ultraviolet or infrared light, thereby suppressing deterioration of the exhibits.

[0034] It is not essential that the flat surface-emitting lighting device 60 be an organic EL lighting device. The flat surface-emitting lighting device 60 may be, for example, a lighting device 60 in which the light emitted from a light-emitting diode is diffused by a diffusion plate.

[0035] The lighting device 60 does not necessarily have to be a flat lighting device that emits light from a surface, but may be a lighting device having a light-emitting diode, a fluorescent lamp, or an incandescent lamp.

[0036] In this embodiment, the description will be given assuming that the lighting device 60 is a rectangular organic EL lighting device. Also, in this embodiment, an example will be described in which the exhibition device 10 is equipped with a plurality of (here, four) lighting devices 60. However, the number of lighting devices 60 may be one.

[0037] <Regarding ceiling panels and how lighting devices are attached to ceiling panels> 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 the shape of a rectangular plate. The edges of each of the four sides of the ceiling panel 50 are fitted into and held in the ceiling panel holding grooves 37 of the frame 32, thereby supporting the ceiling panel 50 at a predetermined height. The height position of the ceiling panel 50 is arbitrary. For example, the ceiling panel 50 may be located at a height of 2 m or more from the installation surface of the lighting device 60.

[0038] 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 lighting device 60 is attached to the first area E1. Here, the lighting device 60 is attached so as to extend 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 observing the ceiling panel 50 from the exhibition space 20S, either the area where the light-emitting surface of the lighting device 60 extends or the area with specular reflectivity is observed.

[0039] More specifically, the ceiling panel 50 includes a plurality of first regions E1. In this embodiment, four first regions E1 are provided in a central region away from the four sides of the ceiling panel 50. The four first regions E1 are rectangular regions 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 adjacent first regions E1 in each direction of the two orthogonal sides of the ceiling panel 50.

[0040] The second regions E2 are located in regions surrounding the four first regions E1 and regions between the four first regions E1 of the ceiling panel 50. Therefore, the second regions E2 are spaced apart by intervals between the multiple first regions E1.

[0041] An illumination device 60 is attached to each of the four first regions E1. The illumination device 60 is formed in a flat rectangular shape that extends in 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.

[0042] The above-described ceiling panel 50 can be realized by a configuration including, for example, a transparent panel 51 and a specular reflective layer 52.

[0043] The transparent panel 51 is formed of a transparent rectangular plate material. The transparent panel 51 is formed of, for example, a glass-based plate material. The glass may be silicate glass, which is mainly composed of silicate, or resin glass such as acrylic glass. Using silicate glass rather than resin glass can increase transparency and provide excellent surface smoothness, making the transparent panel 51 appear less noticeable. The transparent panel 51 may be single-layer glass or double-layer glass. The transparent panel 51 may have a thickness of, for example, 10 mm or less.

[0044] The specular reflective layer 52 is located on the main surface of the transparent panel 51. Here, the specular reflective layer 52 being located on the main surface of the transparent panel 51 means that it is located so as to be in contact with the top or bottom surface of the transparent panel 51. In this embodiment, the specular reflective layer 52 is located in the second region E2 of one of the main surfaces of the transparent panel 51. The specular reflective layer 52 has specular reflectivity at least toward the exhibition space 20S side. Therefore, when the second region 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 lighting device 60, the upper part is visible (see Figure 3).

[0045] The specular reflection layer 52 may be formed, for example, by attaching a mirror film to the upper main surface of the transparent panel 51, which is on the opposite side from the exhibition space 20S. The mirror film is, for example, a resin film on which a metal reflective film is formed by vapor deposition or sputtering. The reflective surface of such a mirror film is adhered or bonded to the upper main surface of the transparent panel 51, thereby forming the specular reflection layer 52 on the upper main surface of the transparent panel 51.

[0046] It is not essential that the specular reflective layer 52 be formed of a mirror film. The upper main surface of the transparent panel 51 may be directly silver-plated, or a mirror coating may be applied to the upper main surface of the transparent panel 51, or a metal plate with a mirror finish may be superimposed on the upper side of the transparent panel 51.

[0047] It is not necessary for the specular reflective layer 52 to be located on the upper surface of the transparent panel 51; the specular reflective layer 52 may be located on the lower surface of the transparent panel 51 so that it has specular reflectivity when viewed from the exhibition space 20S side.

[0048] An illumination device 60 is attached to the ceiling panel 50 so that its light-emitting surface faces the exhibition space 20S. The illumination device 60 may be attached to the ceiling panel 50 in any manner.

[0049] L-shaped positioning and fixing portions 56 are fixed to the four corners of the first region E1 on the upper surface of the ceiling panel 50 by welding, screwing, adhesive, or the like. Then, with the four corners of the lighting device 60 positioned by the positioning and fixing portions 56, the lighting device 60 is placed on the first region E1 of the ceiling panel 50. In this way, the lighting device 60 is attached to the first region E1 of the ceiling panel 50.

[0050] The mounting structure of the lighting device 60 to the ceiling panel 50 is not limited to the above example, and any configuration may be used as long as it can keep the lighting device 60 in a fixed position relative to the ceiling panel 50. For example, the lighting device 60 may be fixed to the ceiling panel 50 with screws.

[0051] A lighting device 60 is attached to a first region E1 of the upper surface of the ceiling panel 50, and a specular reflective layer 52 is provided on a second region E2 of the upper surface, so that the emitted light from the lighting device 60 is irradiated into the exhibition space 20S without being reflected by the specular reflective layer 52.

[0052] <About spot lighting> The exhibition apparatus 10 is equipped with a spot lighting device 70. The spot lighting device 70 is a device that irradiates a downward spot light into the exhibition space 20S. The spot light is light that is irradiated over a narrower range than the illumination range of the above-mentioned illumination device 60. This spot lighting device 70 can brightly illuminate a limited range within the exhibition space 20S.

[0053] The spot lighting device 70 may be any lighting device that irradiates light over a more limited range than the lighting device 60. 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 narrow the emitted light to a certain range, the light distribution characteristics of the light source may be relied upon, or at least one of a reflector and a lens may be used.

[0054] The spot lighting devices 70 are supported in a suspended state by the frame member 30. In this embodiment, four spot lighting devices 70 are supported in a suspended state at each corner of the frame member 30. The spot lighting devices 70 are fixed to the frame member 30 by screws, adhesive, or the like. The spot lighting devices 70 may be fixed to the ceiling panel 50 or the transparent side panel 24.

[0055] The light emitted from the four spotlight devices 70 is directed, for example, above the stand 40 in the exhibition space 20S and toward the central region of the stand 40 in a plan view.

[0056] The position and number of spot lighting devices 70 are arbitrary. For example, one or more spot lighting devices 70 may be provided, or five or more spot lighting devices 70 may be provided. Furthermore, for example, the spot lighting devices 70 may be fixed to the middle portion of the frame 32 in the longitudinal direction. The spot lighting devices 70 may also be omitted.

[0057] In this exhibition device, a lighting device that irradiates light upward, for example, a lighting device that irradiates light toward the ceiling panel 50, may be omitted.

[0058] <About the wiring example> A description will be given of an example layout of the wiring 64a and 64b of the lighting device 60. The wiring 64a and 64b extend from the lighting device 60. The wiring 64a and 64b are, for example, electric wires for supplying power. The wiring 64a and 64b may also include signal lines.

[0059] The lighting devices 60 are arranged in the first area E1, and the wiring 64a, 64b are arranged on the upper surface of the ceiling panel 50 so as to pass through the second area. In this embodiment, the wiring 64a extends from one lighting device 60 toward an external power supply. The wiring 64a extends to cross the second area E2 above the ceiling panel 50. The wiring 64b extends to sequentially connect the four lighting devices 60. The wiring 64b also extends to cross the second area E2 above the ceiling panel 50. Power is supplied to each of the multiple lighting devices 60 via the wiring 64a, 64b to enable them to be driven to emit light.

[0060] Above the ceiling panel 50, the wiring 64a, 64b is located above the specular reflective layer 52. Therefore, even when the ceiling panel 50 is viewed from the exhibition space 20S, the wiring 64a, 64b is hidden by the specular reflective layer 52 in the second area E2.

[0061] Since the spot lighting device 70 is located within the exhibition space 20S, the spot lighting wiring 74 of the spot lighting device 70 is drawn out from the exhibition space 20S to the outside. The spot lighting wiring 74 may be drawn out from any of the ceiling panel 50, the frame member 30, and the transparent side panel 24.

[0062] In this embodiment, an extraction hole 30h is formed in the connecting portion of the frame member 30 with the frame 32 (see FIG. 4). The extraction hole 30h may be formed in the boundary portion between adjacent transparent side panels 24. For example, a glass sealant 28 is filled between the side surfaces of adjacent transparent side panels 24. The extraction hole 30h is set above the glass sealant 28 in an area overlapping the glass sealant. Spot lighting wiring 74 extending from spot lighting devices 70 supported at corners of the frame 32 is led through the glass sealant 28 between the side surfaces of adjacent transparent side panels 24 to the extraction hole 30h, and is then extracted to the outside of the exhibition apparatus 10 through the extraction hole 30h. The spot lighting wiring 74 extracted from each spot lighting device 70 to the outside is extracted along the frame member 30 or over the ceiling panel 50 toward a power source.

[0063] <Example of installation of exhibit device 10> 6 is an explanatory diagram showing an example of installation of the exhibition device 10 in an exhibition room. The exhibition device 10 is placed on a floor 100, which is an installation surface. The height H of the exhibition device 10 is set to, for example, 2 m or more from the floor 100. A ceiling lighting device 120 for the exhibition room is provided on the ceiling 110.

[0064] An exhibit 130 is displayed above a stand 40 in the exhibition device 10. Illumination light from the lighting device 60 is emitted downward from the ceiling panel 50 to illuminate the exhibit 130. Spot light from the spot lighting device 70 is also emitted toward the exhibit 130.

[0065] An observer P of average height observes the exhibit 130. The observer P's line of sight is directed toward the exhibit 130. There is a possibility that the ceiling panel 50 may be included in the observer P's peripheral vision.

[0066] However, because the lighting device 60 is a surface light source, it is unlikely to be dazzling. Furthermore, the scenery below the ceiling panel 50 is reflected in the second area E2, which is not a light source. Therefore, the ceiling panel 50 is perceived as blending visually into the surrounding scenery, making the ceiling panel 50 less noticeable. Furthermore, the portion of the exhibit 130 that is not visible to the observer P can be observed through the mirror surface of the second area E2 of the ceiling panel 50.

[0067] 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 visible to the viewer P can be observed as a smooth and beautiful surface.

[0068] Furthermore, since the specular reflection layer 52 is observed through the transparent panel 51, it can be seen as a ceiling with a sense of depth.

[0069] Moreover, even if the ceiling lighting device 120 on the ceiling 110 enters 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 observe directly. This reduces glare caused by the ceiling lighting device 120 being present in the peripheral vision when observing the exhibit 130 in the exhibition apparatus 10. Also, because the light L from the ceiling lighting device 120 is blocked by the ceiling panel 50, the exhibit 130 is irradiated mainly with illumination light from the lighting device 60, and, if present, with spot illumination light from the spot lighting device 70. This allows the lighting effect of the exhibition apparatus 10 to be effectively exerted.

[0070] <Effects, etc.> According to the exhibition device 10 configured as described above, the lighting device 60 is disposed in the first region E1 of the ceiling panel 50, and illumination light from this lighting device 60 is emitted. The surrounding area of ​​the exhibition space 20S is reflected in the second region E2 of the ceiling panel 50. Therefore, the ceiling panel 50 is less likely to be observed by the viewer P as a light blocker, and the presence of the exhibition device 10 can be reduced. This makes it easier for the viewer P to concentrate on observing the exhibit 130, and an exhibit 130 suitable for viewing the exhibit 130 can be provided.

[0071] Furthermore, since the wiring 64a, 64b extending from the lighting device 60 passes through the second region E2, the wiring 64a, 64b can be made less noticeable. This also makes it easier for the viewer P to concentrate on observing the exhibit 130.

[0072] Furthermore, the ceiling panel 50 has a plurality of first areas E1 that are spaced apart from one another, and a lighting device 60 is attached to each of the first areas E1. Therefore, each of the plurality of lighting devices 60 that are spaced apart from one another can illuminate the exhibit 130 from a different direction. This can reduce the shadow cast on the exhibit 130, making it easier to observe the exhibit 130.

[0073] Moreover, the ceiling panel 50 has a transparent panel 51 made of a glass-based plate material and a specular reflective layer 52 located on the main surface of the transparent panel 51. By using the transparent panel 51 made of a glass-based plate material for the ceiling panel 50, the thickness of the ceiling panel 50 can be made less noticeable.

[0074] Furthermore, the specular reflective layer 52 is provided on the surface opposite the exhibition space 20S. Therefore, when viewed from the viewer P observing the inside of the exhibition space 20S, the specular reflective layer 52 is observed through the transparent panel 51, which is a glass-based plate material. It is easy to increase the smoothness of the surface of the transparent panel 51, which is a glass-based plate material. Furthermore, the viewer P observes the background reflected in the specular reflective layer 52 on the far side of the transparent panel 51, and is therefore able to observe a background with a sense of depth. This allows the ceiling panel 50 to look beautiful.

[0075] Furthermore, 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 less noticeable.

[0076] The main body 20 also has a base 40 on which the exhibit 130 can be placed, and four transparent panels 51 that separate the four sides of the exhibition space 20S on the base 40. Therefore, the exhibit 130 in the exhibition space 20S can be observed from all four sides through the four transparent side panels 24.

[0077] Furthermore, the exhibition space 20S can be partitioned by the transparent panels 51 and the ceiling panel 50, while the presence of each partition can be minimized. This allows the viewer P to concentrate on the exhibit 130.

[0078] Furthermore, if the ceiling panel 50 is positioned at a height of 2 m or more from the installation surface, when an observer P of average height looks at the exhibit 130 in the exhibition space 20S, the ceiling lighting device 120 in the exhibition room can be easily hidden by the ceiling panel 50.

[0079] Furthermore, by providing the exhibition apparatus 10 with the spot lighting device 70, it is possible to brightly illuminate certain parts of the exhibit 130. By drawing 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 74 will be hidden by the ceiling panel 50 when viewed from diagonally below the ceiling panel 50. Therefore, the spot lighting wiring 74 can also be made inconspicuous by the ceiling panel 50.

[0080] {Variation} 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. Some or all of the four transparent side panels 24 may be configured to be openable and closable. For example, any one of the transparent side panels 24 may be supported openably and closably by the lower base 22 and the frame member 30 via a shaft portion. Also, all of the four transparent side panels 24 may be omitted. In this case, a frame for supporting the ceiling panel may be provided separately.

[0081] It is not essential that all of the four transparent side panels 24 be transparent. For example, some of the four transparent side panels 24 may be opaque.

[0082] It is not essential that the main body 20 has a rectangular parallelepiped case shape as in this embodiment. For example, the main body may have a cylindrical case shape, a triangular prism case shape, or a polygonal case shape with pentagons or more.

[0083] In the present embodiment, an example has been described in which the exhibition device 10 is a type that is placed on an installation surface. The exhibition device 10 may be suspended from a ceiling or may be cantilevered by a wall.

[0084] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually contradictory.

[0085] The present specification and drawings disclose the following aspects.

[0086] The first aspect is an exhibition device comprising a main body having a ceiling panel covering the upper side of an exhibition space, and a lighting device that irradiates illumination light into the exhibition space, wherein the ceiling panel has a first area and a second area, the lighting device is attached to the first area, and the ceiling panel has specular reflectivity toward the exhibition space in the second area.

[0087] With this exhibition device, the surrounding area of ​​the exhibition space is reflected in the second area of ​​the ceiling panel. This makes it difficult for the ceiling panel to be seen as a light blocker, and the presence of the exhibition device can be reduced. This makes it possible to provide an exhibition device that is suitable for viewing exhibits.

[0088] In a second aspect, in the display device according to the first aspect, wiring extending from the lighting device passes through the second area, thereby making the wiring less noticeable.

[0089] A third aspect is the exhibition apparatus according to the first or second aspect, wherein the ceiling panel comprises a plurality of the first areas, the second area is spaced apart from the plurality of first areas, and the lighting device is attached to each of the plurality of first areas. This allows the exhibit to be illuminated from different directions by the plurality of lighting devices attached to each of the plurality of first areas that are spaced apart from each other.

[0090] In a fourth aspect, in the display device according to any one of the first to third aspects, the ceiling panel comprises a glass-based plate and a specular reflective layer disposed on a main surface of the glass-based plate. By using the glass-based plate in this way, the thickness of the ceiling panel can be made less noticeable.

[0091] In a fifth aspect, in the display device according to the fourth aspect, the specular reflective layer is provided on the surface opposite the exhibition space. In this case, the surface of the glass-based plate material is exposed on the exhibition space side. This allows the ceiling panel to look beautiful when viewed by an observer inside the exhibition space.

[0092] A sixth aspect is the display device according to any one of the first to fifth aspects, wherein the lighting device is an organic EL lighting device. In this case, the organic EL lighting device has a small thickness, so that the organic EL lighting device attached to the ceiling panel can be made inconspicuous.

[0093] A seventh aspect is the exhibition device according to any one of the first to sixth aspects, in which the main body has a base on which an exhibit can be placed and four transparent side panels that separate the four sides of the exhibition space on the base. In this case, the exhibition space can be observed from all four sides through the four transparent side panels. When observed from any of the four sides, the ceiling panel is hardly noticeable.

[0094] An eighth aspect is the exhibition device according to any one of the first to seventh aspects, wherein the ceiling panel is positioned at a height of 2 m or more from the installation surface. In this way, if the ceiling panel is positioned at a height of 2 m or more from the installation surface, it is easy to hide the ceiling lighting in the exhibition room.

[0095] In a ninth aspect, the exhibition apparatus according to any one of the first to eighth aspects further comprises a spotlight device that irradiates the exhibition space with a downward spotlight, and the spotlight wiring extending from the spotlight device is drawn above the upper surface of the ceiling panel, thereby making the spotlight wiring less noticeable due to the ceiling panel.

[0096] The above description is illustrative in all respects and is not intended to limit the scope of the present invention. It is understood that numerous variations not illustrated can be envisaged without departing from the scope of the present invention. [Explanation of symbols]
