[0005] An object of the present invention is to provide a lighting device capable of installing a decorative body for enhancing the production effect with a simple configuration and without rattling.

Means for Solving the Problems

[0006] A lighting device according to an aspect of the present invention is a lighting device having a grip portion housing, a light emitting portion housing installed in the grip portion housing and emitting light by a light emitter, and a decorative body installed in the light emitting portion housing by elastic deformation.

[0007] In the light-emitting device according to an embodiment of the present invention, the decorative body is formed in the shape of a sheet, and when the decorative body is installed in the light-emitting housing, a predetermined force is applied to each of the ends of the decorative body in a predetermined direction perpendicular to the thickness direction of the decorative body, from the light-emitting housing toward the middle of the decorative body, thereby causing the decorative body to undergo elastic deformation.

[0008] In a light-emitting device according to an aspect of the present invention, the decorative body is formed in the shape of a rectangular sheet having a predetermined thickness, a predetermined vertical dimension, and a predetermined width dimension, and when the decorative body is elastically deformed and viewed in the vertical direction, the decorative body is arc-shaped, and each of the ends of the decorative body in the width direction and the intermediate portion of the outer surface of the arc-shaped decorative body in the width direction are in contact with the light-emitting unit housing.

[0009] In the light-emitting device according to an embodiment of the present invention, when the decorative body is in the state of elastic deformation, and the decorative body and the light-emitting unit housing are viewed in the longitudinal direction, a part of the surface of the light-emitting unit housing in the internal space of the light-emitting unit housing is formed in a recessed arc shape, and the radius of the arc of the arc-shaped decorative body is smaller than the radius of the arc of the part of the surface in the internal space of the arc-shaped light-emitting unit housing.

[0010] In an embodiment of the present invention, the light-emitting housing comprises a main body portion of the light-emitting housing which is formed in the shape of a rectangular plate, and an opening forming portion which is formed in the shape of a cylinder, and the light-emitting housing is configured to be divided into a first light-emitting housing component and a second light-emitting housing component by a plane that includes the center of the light-emitting housing and is perpendicular to the thickness direction of the light-emitting housing.

[Figure 18] It is a view corresponding to FIG. 11(c), and is a view showing a lighting device according to the seventh modification.

Mode for Carrying Out the Invention

[0015] The lighting device 1 according to the embodiment of the present invention is, for example, one that is held and used by an audience at a concert venue. As shown in FIGS. 1 to 8, the lighting device 1 includes a grip portion housing 3, a light emitting portion housing 5 that is integrally installed in the grip portion housing 3, and a decoration body 7 that is integrally installed in the light emitting portion housing 5 by elastic deformation.

[0016] Light-emitting device 1 can be used not only at concert venues but also at sporting event venues, theme parks, and other locations. Specifically, spectators may use light-emitting device 1 to cheer on athletes at sporting event venues, and cast members and guests may use it at theme parks to enhance the atmosphere and enjoyment. Furthermore, light-emitting device 1 can be used as a light-emitting device by spectators in concert venues even without the installation of the decorative body 7.

[0017] Here, for the sake of explanation, we define a predetermined direction in the light-emitting device 1 as the X direction (width direction), a predetermined direction perpendicular to the X direction as the Y direction (thickness direction), and a direction perpendicular to both the X and Y directions as the Z direction (vertical direction).

[0018] The gripping part housing 3 is made of a material such as opaque synthetic resin, and constitutes the gripping part 9 of the light-emitting device 1. The gripping part 9 is the part that a person holds with their hand when using the light-emitting device 1.

[0019] The light-emitting part housing 5 is made of a transparent or translucent (including colored transparent and colored translucent) synthetic resin or other material that transmits light (for example, visible light), and constitutes the light-emitting part 11. The light-emitting part 11 becomes the part of the light-emitting device 1 that glows when the light-emitting device 1 is used. The light-emitting part housing 5 is integrally installed with the gripping part housing 3.

[0020] The light-emitting housing 5 is designed to emit light from a light-emitting element (not shown) composed of, for example, red LEDs, green LEDs, and blue LEDs. The light-emitting element is also integrally provided with the gripping part 9, for example.

[0021] The decorative body 7 is made of a material such as a synthetic resin that is elastic, and is designed to be integrally installed on the light-emitting unit housing 5 by elastic deformation. Alternatively, a part of the decorative body 7 may be elastic, and the decorative body 7 may be integrally installed on the light-emitting unit housing 5 by the elastic deformation of this elastic part.

[0022] The decorative body 7, which is elastically deformed by being installed on the light-emitting unit housing 5, is in contact with the light-emitting unit housing 5 at multiple points. At these contact points, the decorative body 7 biases the light-emitting unit housing 5. In other words, the decorative body 7 receives force (reaction force) from the light-emitting unit housing 5 at these multiple points.

[0023] As a result, the decorative element 7 is integrally installed on the light-emitting unit housing 5 without moving relative to it. The multiple contact points on the light-emitting unit housing 5 where the decorative element 7 abuts constitute the decorative element holding portion 13, and the multiple contact points on the decorative element 7 where the light-emitting unit housing 5 abuts constitute the decorative element being held portion 15.

[0024] Furthermore, the decorative element 7 is installed, for example, inside the light-emitting unit housing 5 within the light-emitting unit housing 5. The decorative element 7 is made of a transparent or translucent (including colored transparent and colored translucent) synthetic resin or other material that transmits light. Light irradiated onto the decorative element 7 is transmitted through the decorative element 7 and also reflected off its surface.

[0025] The decorative element 7, although not shown in the illustration, has a pattern (design) including letters, figures, symbols, etc. The pattern may also include holograms (including 3D holograms) or latent images, as used on banknotes. Light shone on the pattern of the decorative element 7 is designed to be reflected by the surface of the pattern without passing through, but the light shone on the pattern of the decorative element 7 may also be reflected by the surface of the pattern and then transmitted through the pattern. Furthermore, the pattern may be omitted from the decorative element 7.

[0026] The decorative element 7 may also function as a light-diffusing member that diffuses light. That is, light irradiated onto the decorative element 7 may be diffused by the decorative element 7 and irradiated in various directions.

[0027] The gripping unit housing 3 has an internal space (gripping unit housing internal space) 19 surrounded by a wall (gripping unit housing wall) 17. This internal space 19 is connected to the outside of the gripping unit housing 3 by an opening (gripping unit housing opening) 21 provided in the gripping unit housing 3. The light-emitting unit housing 5 also has an internal space (light-emitting unit housing internal space) 25 surrounded by a wall (light-emitting unit housing wall) 23, and this internal space 25 is connected to the outside of the light-emitting unit housing 5 by an opening (light-emitting unit housing opening) 27 provided in the light-emitting unit housing 5.

[0028] The internal space 19 of the gripping unit housing, although not shown, contains a power supply unit, a control unit (for example, a control unit comprising a CPU and memory), and a light-emitting element. The light-emitting element is located at the opening 21 of the gripping unit housing, and the light emitted by the light-emitting element exits the gripping unit housing housing 3 from the opening 21. The control unit controls the mode of light emission from the light-emitting element using power supplied from the power supply unit located in the power supply unit. The control unit controls the saturation, brightness, hue, illumination, blinking, etc., of the light emitted by the light-emitting element.

[0029] At the opening 21 of the gripping section housing, a light-emitting section housing engagement portion (for example, a female screw) 29 is provided that engages with the light-emitting section 11. At the opening 27 of the light-emitting section housing, a gripping section housing engagement portion (for example, a male screw) 31 is provided that engages with the gripping section 9. The light-emitting section housing engagement portion 29 and the gripping section housing engagement portion 31 engage (screw) with each other, so that the light-emitting section housing 5 is integrally installed in the gripping section housing 3. Then, the openings 21 and 27 of the gripping section housing are closed, and the internal space 19 of the gripping section housing and the internal space 25 of the light-emitting section housing are connected to each other.

[0030] In the light-emitting device 1, some of the light emitted by the light-emitting body and irradiated into the internal space 25 of the light-emitting body housing passes through the decorative element 7 and is reflected by the decorative element 7, and then passes through the fleshy part of the light-emitting body housing 5 and exits to the outside of the light-emitting body housing 5. In addition, the remaining light emitted by the light-emitting body and irradiated into the internal space 25 of the light-emitting body housing 25 passes through the fleshy part of the light-emitting body housing 5 and exits to the outside of the light-emitting body housing 5. As a result, when viewed from outside the light-emitting body 11, the decorative element 7 and the light-emitting body housing 5 light up when the light-emitting body emits light in the light-emitting device 1.

[0031] The decorative element 7 is formed in a sheet-like shape, with the thickness dimensions being equal at all points. When no external force is applied, the sheet-like decorative element 7 is, for example, flat.

[0032] When the decorative element 7 is installed in the light-emitting housing 5, a predetermined force is applied from the light-emitting housing 5 to each end of the decorative element 7 in the width direction (X direction) toward the center of the decorative element 7. The width direction of the decorative element 7 is a predetermined direction perpendicular to the thickness direction (Y direction) of the decorative element 7. Due to the application of the predetermined force, the decorative element 7 undergoes elastic deformation and bends into an arc shape (flexes in an arc shape), as shown in Figures 7 and 8.

[0033] The pattern (not shown) of the decorative body 7 is drawn on one or both sides of the sheet-like decorative body 7 in the thickness direction. In the embodiment where the pattern is drawn on both sides of the sheet-like decorative body 7 in the thickness direction, all of the patterns drawn on one side of the sheet-like decorative body 7 in the thickness direction overlap with all of the patterns drawn on the other side of the sheet-like decorative body 7 in the thickness direction. For example, the pattern drawn on one side of the decorative body 7 in the thickness direction is a predetermined character viewed from the front, and the pattern drawn on the other side of the decorative body 7 in the thickness direction is the same predetermined character viewed from the back. However, the pattern drawn on the other side of the decorative body 7 in the thickness direction may be different from the pattern drawn on one side of the decorative body 7 in the thickness direction, and the patterns drawn on one side and the patterns drawn on the other side may not overlap.

[0034] Furthermore, the decorative element 7 is formed in the shape of a rectangular sheet having a predetermined thickness dimension, a predetermined vertical dimension (a predetermined one direction perpendicular to the thickness direction; the Z direction), and a predetermined width dimension (the X direction). Cards, bromides, etc., can be displayed as the decorative element 7.

[0035] When the sheet-like decorative element 7 is installed on the light-emitting unit housing 5 and is bent into an arc shape, the thickness direction of the decorative element 7 varies depending on the part of the decorative element 7. In other words, the thickness direction of the bent sheet-like decorative element 7 does not coincide with all parts of the decorative element 7. Therefore, the thickness direction of the decorative element 7 is generally in the Y direction. Also, the vertical direction of the decorative element 7 is in the Z direction, and the width direction of the decorative element 7 is also generally in the X direction.

[0036] When the decorative body 7 is installed in the light-emitting unit housing 5 and undergoes elastic deformation, we view the decorative body 7 in the vertical direction (Z direction). As shown in Figures 7, 8, and 11(c), the decorative body 7 is arc-shaped, and both ends 7A and 7B of the decorative body 7 in the width direction, as well as the middle part (for example, the central part) 7C of the outer circumferential surface (convex side) of the arc-shaped decorative body 7 in the width direction, are in contact with the light-emitting unit housing 5.

[0037] When the decorative body 7 is elastically deformed in an arc shape, a predetermined force is applied from the light-emitting unit housing 5 to each of the two ends 7A and 7B in the width direction of the decorative body 7, directed toward the center of the decorative body 7. Also, when the decorative body 7 is elastically deformed in an arc shape, a predetermined force is applied from the light-emitting unit housing 5 to the outer circumference of the arc-shaped decorative body 7, specifically to the central part 7C in the width direction of the decorative body 7, directed toward the center of the arc of the decorative body 7.

[0038] In other words, when the decorative body 7 is elastically deformed in an arc shape and viewed in the Z direction, the first force is applied to one end 7A in the width direction of the decorative body 7, the second force is applied to the other end 7B in the width direction of the decorative body 7, and the third force is applied to the central part 7C in the width direction of the decorative body 7. These first, second, and third forces are in equilibrium, and the decorative body 7 is supported by the light-emitting unit housing 5 at three points that are separated from each other, and is integrally installed on the light-emitting unit housing 5.

[0039] When viewing the light-emitting housing 5 in the Z direction, it is observed that a portion of the surface of the light-emitting housing 5 within its internal space (internal space of the light-emitting housing) 25 (arc-shaped surface of the light-emitting housing) 33 is formed in a recessed arc shape. Furthermore, the radius of the arc of the arc-shaped decorative element 7 is smaller than the radius of the arc of the portion of the surface (arc-shaped surface of the light-emitting housing) 33 within the internal space 25 of the arc-shaped light-emitting housing 5.

[0040] When the decorative element 7 is installed on the light-emitting unit housing 5 and the decorative element 7 is elastically deformed, we view it in the Z direction. The center of the arc of the decorative element 7 lies on a straight line (not shown, the center line of the decorative element arc) that passes through the center of the arc of the decorative element 7 and extends in the Y direction. Similarly, the center of the arc of the arc-shaped surface 33 of the light-emitting unit housing lies on a straight line (not shown, the center line of the light-emitting unit housing arc) that passes through the center of the arc of the arc-shaped surface 33 of the light-emitting unit housing 33 and extends in the Y direction. The center line of the decorative element arc and the center line of the light-emitting unit housing arc coincide with each other.

[0041] As shown in Figure 1, the light-emitting unit housing 5 is composed of a light-emitting unit housing main body 35 and an opening forming portion 37. The light-emitting unit housing main body 35 is formed in the shape of a rectangular plate with a predetermined thickness, width, and height. The opening forming portion 37 is formed in the shape of a cylinder with a predetermined diameter and height (length).

[0042] The internal space of the main body 35 of the light-emitting unit housing 5 is also formed in a rectangular plate shape. However, the predetermined thickness value of the internal space of the main body 35 of the light-emitting unit housing is slightly smaller than the predetermined thickness value of the external shape of the main body 35 of the light-emitting unit housing. The predetermined width value of the internal space of the main body 35 of the light-emitting unit housing is slightly smaller than the predetermined width value of the external shape of the main body 35 of the light-emitting unit housing. Also, the predetermined vertical dimension value of the internal space of the main body 35 of the light-emitting unit housing is slightly smaller than the predetermined vertical dimension value of the external shape of the main body 35 of the light-emitting unit housing. The opening forming portion 37 is formed in a cylindrical shape.

[0043] The thickness dimension of the light-emitting unit housing main body 35 is smaller than the width dimension of the light-emitting unit housing main body 35. The width dimension of the light-emitting unit housing main body 35 is smaller than the vertical dimension of the light-emitting unit housing main body 35. The outer diameter dimension of the opening forming portion 37 is larger than the thickness dimension of the light-emitting unit housing main body 35 and smaller than the width dimension of the light-emitting unit housing main body 35. The vertical dimension of the opening forming portion 37 is approximately the same as the outer diameter dimension of the opening forming portion 37.

[0044] The opening-forming portion 37 protrudes from one end of the main body portion 35 of the light-emitting unit housing in the vertical direction. In the width and thickness directions, the opening-forming portion 37 is located in the center of the main body portion 35 of the light-emitting unit housing. The internal space 25 of the light-emitting unit housing 5 is formed by the connection between the internal space of the main body portion 35 of the light-emitting unit housing and the internal space of the opening-forming portion 37.

[0045] Furthermore, the thickness of the light-emitting unit housing wall portion 23 (the wall portion of the light-emitting unit housing main body portion 35 and the wall portion of the opening forming portion 37) is approximately equal at all points on the light-emitting unit housing 5.

[0046] As shown in Figures 5, 6, and 11(a)(b), the light-emitting housing 5 is configured to be divided into a first light-emitting housing component 41 and a second light-emitting housing component 43 by a central plane 39 of the light-emitting housing. The central plane 39 of the light-emitting housing is a plane that includes the center of the light-emitting housing 5 and is perpendicular to the thickness direction of the light-emitting housing 5.

[0047] The first light-emitting unit housing structure 41 and the second light-emitting unit housing structure 43 are substantially symmetrical with respect to the light-emitting unit housing central plane 39. The arc-shaped surface 33 of the light-emitting unit housing, which is a recessed portion in the arc shape when viewed in the vertical direction on the surface of the internal space 25 of the light-emitting unit housing 5, is formed on both the first light-emitting unit housing structure 41 and the second light-emitting unit housing structure 43. In the light-emitting unit housing 5, the arc-shaped surfaces 33 of the light-emitting unit housing face each other with the light-emitting unit housing central plane 39 in between. The distance in the Y direction between the arc-shaped surface 33 of the light-emitting unit housing structure 41 and the arc-shaped surface 33 of the light-emitting unit housing structure 43 is as follows: It is largest in the center of the width direction (X direction) of the light-emitting unit housing structures 41 and 43, and gradually decreases towards the edges.

[0048] The arc-shaped surface 33 of the light-emitting unit housing is formed on the wall portion of the first light-emitting unit housing component 41 that constitutes the main body portion 35 of the light-emitting unit housing, specifically the portion (bottom wall portion 45) where the thickness direction is in the same direction as the thickness of the light-emitting unit housing 5 (see Figure 5). Furthermore, the arc-shaped surface 33 of the light-emitting unit housing is formed on the wall portion (bottom wall portion 45) of the second light-emitting unit housing component 43 that constitutes the main body portion 35 of the light-emitting unit housing, specifically where the thickness direction is in the same direction as the thickness of the light-emitting unit housing 5 (see Figure 6).

[0049] To explain further, as shown in Figure 5, the first light-emitting unit housing component 41, which constitutes the main body portion 35 of the light-emitting unit housing, is formed in a shallow rectangular box shape with one bottom wall portion 45 and four side walls 47, 49, 51, and 53. The arc-shaped surface 33 of the light-emitting unit housing is formed on the bottom wall portion 45 (the inner surface of the bottom wall portion 45; the surface that becomes the inside of the box) of the rectangular box-shaped portion. As shown in Figure 6, the second light-emitting unit housing component 43 also has its arc-shaped surface 33 formed on the bottom wall portion 45 of the rectangular box-shaped portion, similar to the first light-emitting unit housing component 41.

[0050] The arc-shaped surface 33 of the light-emitting unit housing is formed in the central part of the light-emitting unit housing components 41 and 43 that constitute the main body portion 35 of the light-emitting unit housing, excluding both ends, in the vertical direction (Z direction). In the width direction (X direction), the arc-shaped surface 33 of the light-emitting unit housing is formed in the part of the light-emitting unit housing components 41 and 43 that constitute the main body portion 35, excluding the side wall portions 51 and 53. The parts of the light-emitting unit housing components 41 and 43 that constitute the opening forming portion 37 are formed in a semi-cylindrical shape.

[0051] As shown in Figure 1, the gripping section housing 3 is formed in a bottomed cylindrical shape. The female thread constituting the light-emitting section housing engagement portion 29 of the gripping section housing 3 is formed on the inner circumference of the cylindrical part of the gripping section housing 3, on the side of the gripping section housing opening 21. The gripping section housing 3 is also provided with an operation switch 55. By operating the operation switch 55 as appropriate, the power to the light-emitting device 1 is turned on and off, and the mode of light emission from the light-emitting section 11 is changed.

[0052] As shown in Figures 2 and 3, the male screw constituting the gripping housing engagement portion 31 of the light-emitting housing 5 is formed on the outer circumference of the opening forming portion 37 of the light-emitting housing 5, on the side of the light-emitting housing opening 27. Also, as shown in Figure 2, a packing 57 is provided on the outer circumference of the opening forming portion 37 of the light-emitting housing 5, on the side of the light-emitting housing main body portion 35.

[0053] As shown in Figures 5, 6, and 9, the first light-emitting unit housing structure 41 is provided with a tip-side engaging portion 59, and the second light-emitting unit housing structure 43 is also provided with a tip-side engaging portion 61. The tip-side engaging portion 59 is provided on the side wall portion 49 of the first light-emitting unit housing structure 41, and the tip-side engaging portion 61 is provided on the side wall portion 49 of the second light-emitting unit housing structure 43.

[0054] When the first light-emitting unit housing component 41 and the second light-emitting unit housing component 43 are assembled to form the light-emitting unit housing 5, the tip-side engaging component 61 engages with the tip-side engaging component 59, and the male screw constituting the gripping unit housing engaging component 31 is formed. The tip-side engaging component 61 engages with the tip-side engaging component 59 (see Figure 9). As is clear from Figure 9, the tip side of the first light-emitting unit housing component 41 (opposite the opening forming component 37) does not separate from the tip side of the second light-emitting unit housing component 43, especially in the Y direction.

[0055] With the first light-emitting unit housing component 41 and the second light-emitting unit housing component 43 assembled, the gripping unit housing 3 is placed on the light-emitting unit housing 5 so that the female thread of the light-emitting unit housing engagement portion 29 and the male thread of the gripping unit housing engagement portion 31 are screwed into each other. The first light-emitting unit housing component 41, the second light-emitting unit housing component 43 and the gripping unit housing 3 are then integrated into one unit. In this integrated state, the tip-side engagement portion 61 is locked to the tip-side engagement portion 59.

[0056] As shown in Figures 4, 5, 7, and 8, the decorative element holding portion 13 of the light-emitting unit housing 5 is provided on the first light-emitting unit housing component 41. The decorative element holding portion 13 is composed of a plurality of protrusions 63. The plurality of protrusions 63 constituting the decorative element holding portion 13 are provided on the side wall portions 51 and 53 of the first light-emitting unit housing component 41. The plurality of protrusions (for example, three protrusions) 63 provided on the side wall portion 51 are arranged at a predetermined interval in the Z direction. The plurality of protrusions (for example, three protrusions) 63 provided on the side wall portion 53 are also arranged at a predetermined interval in the Z direction.

[0057] Taking the projection 63 provided on the side wall portion 53 of the first light-emitting unit housing structure 41 as an example, the projection 63 will be described in more detail with reference to Figure 7(b). The cross-sectional shape of the projection 63 (the shape of the cross section by a plane perpendicular to the Z direction) is formed as a trapezoid. In this trapezoid, two of the four angles are 90°, one of the four angles is acute, and the other of the four angles is obtuse.

[0058] The projection 63 is provided on the side wall 53 such that the 90° corner is located on the outside (opposite the center of the first light-emitting unit housing structure 41 in the X direction), and the acute and obtuse corners are located on the inside.

[0059] In the X direction, one end of the projection 63 is located at the center of the side wall portion 53, and the other end is located closer to the center of the first light-emitting unit housing structure 41 than the side wall portion 53. The tip of the projection 63 (the other end) is located closer to the center of the first light-emitting unit housing structure 41 than the side wall portion 53 in the X direction. Also, in the X direction, the obtuse angle of the projection 63 is located closer to the center of the first light-emitting unit housing structure 41 than the side wall portion 53. Furthermore, in the X direction, the acute angle of the projection 63 is located closer to the center of the light-emitting unit housing structure 41 (towards the tip of the projection 63) than the obtuse angle of the projection 63. A bevel (guide surface) 65 is formed on the tip of the projection 63.

[0060] The guide surface 65 is provided to facilitate the installation of the decorative element 7 onto the first light-emitting unit housing structure 41. That is, when installing the decorative element 7 onto the first light-emitting unit housing structure 41, the end 7A of the decorative element 7 is guided by contacting and sliding against the guide surface 65.

[0061] Furthermore, in the Y direction, the projection 63 protrudes from the side wall portion 53 beyond the aforementioned central plane 39 of the light-emitting unit housing. As shown in Figure 8(b), a separate projection (small projection) 69 is provided on the side wall portion 53 where the projection 63 is not provided. The small projection 69 extends between multiple projections 63. The cross-sectional shape of the small projection 69 (the shape of the cross-section by a plane perpendicular to the Z direction) is such that the projection 63 and the side wall portion 53 have notches 71.

[0062] A recess 67 is provided in the side wall 53 of the second light-emitting unit housing structure 43. The cross-sectional shape of the recess 67 (the shape of the cross-section by a plane perpendicular to the Z direction) is rectangular. When the first light-emitting unit housing structure 41 is installed in the second light-emitting unit housing structure 43, the projection 63 and the small projection 69 fit into the recess 67 (see Figures 7 and 8).

[0063] Furthermore, the first light-emitting unit housing structure 41 is installed on the second light-emitting unit housing structure 43. At this time, the second light-emitting unit housing structure 43 is positioned relative to the first light-emitting unit housing structure 41 by the tip-side engaging portion 59 and tip-side engaging portion 61 (see Figure 9), along with the recess 67, projection 63 and small projection 69. In other words, the second light-emitting unit housing structure 43 is positioned relative to the first light-emitting unit housing structure 41 in the Z and X directions.

[0064] The decorative body holding portion 15 of the decorative body 7 is composed of both ends 7A, 7B and the central portion 7C of the decorative body 7 in the X direction. When the decorative body 7 is installed in the light-emitting unit housing 5, as shown in Figures 7 and 8, both ends 7A, 7B of the decorative body 7 in the X direction simultaneously contact the projection 63 and the side wall portions 51, 53, and are biased from the light-emitting unit housing 5 (first light-emitting unit housing component 41). When the decorative body 7 is installed in the light-emitting unit housing 5, the central portion 7C of the decorative body 7 in the X direction contacts the bottom wall portion 45 and is biased from the light-emitting unit housing 5 (first light-emitting unit housing component 41).

[0065] This ensures that the decorative element 7 is positioned relative to the light-emitting housing 5 (first light-emitting housing component 41) in the X and Y directions. The positioning of the decorative element 7 relative to the light-emitting housing 5 (first light-emitting housing component 41) in the Z direction is achieved by the decorative element 7 contacting the contact portion 73 shown in Figure 4.

[0066] In Figures 4 to 6, the component indicated by reference numeral 75 is a light-diffusing and transmitting material that diffuses and transmits the light emitted by the light-emitting element. The light-diffusing and transmitting material 75 is formed in a flat plate shape and is provided in the vicinity of the opening-forming portion 37 of the light-emitting element housing main body portion 35, with its thickness direction being the Z direction. More precisely, the presence of the light-diffusing and transmitting material 75 divides the internal space 25 of the light-emitting element housing. Note that the light-diffusing and transmitting material 75 may be omitted.

[0067] The first light-emitting unit housing structure 41 and the second light-emitting unit housing structure 43 are formed substantially symmetrically with respect to a central plane. The central plane is a plane that includes the centers of the first light-emitting unit housing structure 41 and the second light-emitting unit housing structure 43 and is perpendicular to the X direction.

[0068] Furthermore, as shown in Figure 1, the bottom wall portion 45 of the light-emitting unit housing 5 has a diamond-shaped pattern of raised and recessed areas, but this diamond-shaped pattern may be removed. Also, the decorative body 7 may have a diamond-shaped pattern of raised and recessed areas.

[0069] Next, the assembly of the light-emitting device 1 will be described. In the state shown in Figure 11(a), the decorative body 7 is appropriately curved and placed on the first light-emitting unit housing component 41 (see Figure 11(b)). Subsequently, the second light-emitting unit housing component 43 is placed on the first light-emitting unit housing component 41 (see Figure 11(c)). Subsequently, the gripping unit housing 3 (gripping unit 9) is placed on the first light-emitting unit housing component 41 and the second light-emitting unit housing component 43 (see Figure 1). Disassembly of the light-emitting device 1 is performed in the reverse order of assembly as described above. Replacement of the decorative body 7 is performed by appropriately performing the disassembly and assembly described above.

[0070] To activate the light-emitting device 1, the operation switch 55 is operated appropriately to turn on the power to the light-emitting device 1, which has a battery installed in its battery compartment. After this, the light-emitting part 11 is illuminated by operating the operation switch 55 appropriately.

[0071] The light-emitting device 1 comprises a gripping housing 3, a light-emitting housing 5 installed in the gripping housing 3 and illuminated by a light-emitting element, and a decorative element 7 installed in the light-emitting housing 5. This decorative element 7 enhances the visual effect when used in concerts and other events. Furthermore, the light-emitting device 1 is configured so that the decorative element 7 is installed in the light-emitting housing 5 by elastic deformation. This allows for a simple configuration of the light-emitting housing 5 without complicating its structure, and enables the decorative element 7 to be installed in the light-emitting housing 5 without any rattling.

[0072] In the light-emitting device 1, with the decorative body 7 installed in the light-emitting housing 5, a predetermined force is applied to each end of the sheet-like decorative body 7, moving from the light-emitting housing 5 towards the center of the decorative body 7. As a result, the decorative body 7 undergoes elastic deformation and bends into an arc shape.

[0073] This allows the decorative body 7 to be easily bent into an arc shape by applying force to it by hand. Furthermore, it makes it easy to install decorative body 7 that is not installed in the light-emitting unit housing 5 into the light-emitting unit housing 5, and to remove decorative body 7 that is installed in the light-emitting unit housing 5 from the light-emitting unit housing 5.

[0074] Furthermore, in the light-emitting device 1, the decorative body 7 is formed in the shape of a rectangular sheet, and when viewed in the vertical direction (Z direction) of the decorative body 7 while it is installed in the light-emitting unit housing 5, the decorative body 7 is arc-shaped. Also, in the light-emitting device 1, when viewed in the Z direction while the decorative body 7 is installed in the light-emitting unit housing 5, both ends 7A and 7B in the width direction of the decorative body 7, and the central part 7C in the width direction of the outer surface of the arc-shaped decorative body 7, are in contact with the light-emitting unit housing 5.

[0075] As a result, the decorative element 7 installed on the light-emitting unit housing 5 is in contact with the light-emitting unit housing 5 at three points when viewed in the Z direction: at both ends 7A, at the central part 7C of the convex surface 7B, and the decorative element 7 is supported by the light-emitting unit housing 5 in a stable state.

[0076] Furthermore, in the light-emitting device 1, the radius of the arc of the decorative element 7 is smaller than the radius of the arc of a part 33 on the surface of the internal space 25 of the light-emitting unit housing 5. This ensures that the decorative element 7 can be reliably brought into contact with the light-emitting unit housing 5 at the three locations mentioned above. In addition, a gap 77 is formed between the light-emitting unit housing 5 and the decorative element 7 installed in the light-emitting unit housing 5. This gap 77 causes the light emitted by the light-emitting element to refract and reflect in a more complex manner, further enhancing the decorative effect.

[0077] Furthermore, in the light-emitting device 1, the light-emitting housing 5 is configured to be divided into a first light-emitting housing component 41 and a second light-emitting housing component 43 by a central plane 39 of the light-emitting housing. This makes it easier to mold the light-emitting housing 5. In addition, large openings are formed in the first light-emitting housing component 41 and the second light-emitting housing component 43, making it easy to install the decorative element 7 on the light-emitting housing 5 and to replace the decorative element 7 installed on the light-emitting housing 5.

[0078] Here, we will describe the first modified example of the light-emitting device 1a with reference to Figure 12. Note that in Figure 12, the decorative body holder 13 and other parts are omitted from the display.

[0079] The first modified example of the light-emitting device 1a differs from the light-emitting device 1 according to the embodiment of the present invention in that two decorative elements 7 are installed inside the light-emitting unit housing 5, but otherwise it is configured in the same way as the light-emitting device 1 according to the embodiment of the present invention.

[0080] In the first modified example of the light-emitting device 1a, the first decorative element 7 is installed on the first light-emitting unit housing structure 41, and the second decorative element 7 is installed on the second light-emitting unit housing structure 43. The first decorative element 7 installed on the first light-emitting unit housing structure 41 and the second decorative element 7 installed on the second light-emitting unit housing structure 43 face each other.

[0081] Next, a second modified example of the light-emitting device 1b will be described with reference to Figure 13. Note that in Figure 13, the second light-emitting unit housing component 43 and other elements are omitted. The second modified example of the light-emitting device 1b differs from the light-emitting device 1 according to the embodiment of the present invention in that the radius of the arc of the arc-shaped surface 33 of the light-emitting unit housing 5 is equal to the radius of the arc of the decorative element 7, but in other respects, it is configured in the same way as the light-emitting device 1 according to the embodiment of the present invention.

[0082] In the second modified example, the light-emitting device 1b, almost the entire surface of one side in the thickness direction of the decorative body 7 is in contact with the arc-shaped surface 33 of the light-emitting housing 5.

[0083] Next, the third modified light-emitting device 1c will be described with reference to Figure 14. Note that in Figure 14, the second light-emitting unit housing component 43 and other elements are omitted. The third modified light-emitting device 1c differs from the light-emitting device 1 according to the embodiment of the present invention in that the radius of the arc of the arc-shaped surface 33 of the light-emitting unit housing 5 is smaller than the radius of the arc of the decorative element 7. Other aspects are the same as those of the light-emitting device 1 according to the embodiment of the present invention. In the third modified light-emitting device 1c, only both ends of the decorative element 7 in the width direction are in contact with the light-emitting unit housing 5.

[0084] Next, the fourth modified example of the light-emitting device 1d will be described with reference to Figure 15. Note that in Figure 15, the second light-emitting unit housing component 43 and other components are omitted. The fourth modified example of the light-emitting device 1d differs from the light-emitting device 1 according to the embodiment of the present invention in that both ends of the decorative body 7 in the width direction are also supported by ribs 79 provided on the light-emitting unit housing 5, but in other respects, it is configured the same as the light-emitting device 1 according to the embodiment of the present invention. In the fourth modified example of the light-emitting device 1d, both ends of the decorative body 7 in the width direction are sandwiched between the projection 63 and the rib 79.

[0085] Next, a fifth modified example of the light-emitting device 1e will be described with reference to Figure 16. Note that in Figure 16, the second light-emitting unit housing structure 43 and other components are omitted from the display. The fifth modified example of the light-emitting device 1e differs from the light-emitting device 1 according to the embodiment of the present invention in that a flat surface 81 is provided instead of the arc-shaped surface 33 of the light-emitting unit housing, but in other respects, it is configured in the same way as the light-emitting device 1 according to the embodiment of the present invention. In the fifth modified example of the light-emitting device 1e, the bottom wall portion 45 of the first light-emitting unit housing structure 41 is formed in a flat plate shape.

[0086] Next, the sixth modified example of the light-emitting device 1f will be described with reference to Figure 17. The sixth modified example of the light-emitting device 1f differs from the light-emitting device 1 according to the embodiment of the present invention in that the decorative body 7a is installed on the light-emitting unit housing 5 using the decorative body holder 83, but in other respects it is configured the same as the light-emitting device 1 according to the embodiment of the present invention.

[0087] To further explain, the sixth modified example of the light-emitting device 1f comprises a gripping part housing 3 (not shown in Figure 17), a light-emitting part housing 5, a decorative element 7a, and a decorative element holder 83. The light-emitting part housing 5 is installed on the gripping part housing 3. The decorative element 7a is installed on the light-emitting part housing 5.

[0088] The decorative element holder 83 is designed to be installed in the light-emitting unit housing 5 by elastic deformation. The installation of the decorative element holder 83 in the light-emitting unit housing 5 maintains the state in which the decorative element 7a is integrally installed in the light-emitting unit housing 5. When the decorative element 7a and the decorative element holder 83 are installed in the light-emitting unit housing 5, the decorative element 7a is positioned between the bottom wall portion 45 of the light-emitting unit housing 5 and the decorative element holder 83. The decorative element 7a is sandwiched between the bottom wall portion 45 and the decorative element holder 83.

[0089] In the configuration shown in Figure 17, the radius of the arc-shaped surface 33 of the light-emitting unit housing, the radius of the decorative element 7a, and the radius of the decorative element holder 83 are all the same. However, these three radii may be different from each other, or one of the three radii may be different from the other two.

[0090] As decorative items 7a, cards, bromides, photographs, transparent sheets, trading cards, etc. can be displayed.

[0091] In the light-emitting device 1f, when the decorative body 7a and the decorative body holder 83 are viewed in the thickness direction, the external shape of the decorative body 7a and the external shape of the decorative body holder 83 are approximately the same. However, the external shape of the decorative body 7a may differ from the external shape of the decorative body holder 83 when viewed in the thickness direction, and the external shape of the decorative body 7a may be smaller than that of the decorative body holder 83. Furthermore, the decorative body 7a may or may not be elastic.

[0092] The light-emitting device 1f is installed in the light-emitting unit housing 5 by elastic deformation, and is equipped with a decorative element holder 83 that maintains the state in which the decorative element 7a is installed in the light-emitting unit housing 5 by being installed in the light-emitting unit housing 5. As a result, even decorative elements 7a that have almost no elasticity or whose external shape is smaller than the decorative element holder 83 can be installed in the light-emitting unit housing 5.

[0093] Next, the seventh modified example, the light-emitting device 1g, will be described with reference to Figure 18. The seventh modified example, the light-emitting device 1g, differs from the sixth modified example, the light-emitting device 1f, in that the arc-shaped surface 33 of the light-emitting device housing 5 is convex; otherwise, it is configured similarly to the sixth modified example, the light-emitting device 1f.

[0094] In other words, in the sixth modified light-emitting device 1f, when viewed in the Z direction, the arc-shaped surface 33 of the light-emitting part housing is concave, so the light-emitting part housing 5 (arc-shaped surface 33 of the light-emitting part housing) appears to have the shape of a biconvex lens. In contrast, in the seventh modified light-emitting device 1g, the arc-shaped surface 33 of the light-emitting part housing is concave, so the light-emitting part housing 5 (arc-shaped surface 33 of the light-emitting part housing) appears to have the shape of a biconcave lens.

[0095] In addition, in the seventh modified example of the light-emitting device 1g, the decorative element holder 83 may also be provided with the function of the decorative element 7. Alternatively, the decorative elements 7 and 7a may be installed only on the first light-emitting unit housing structure 41.

[0096] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment. For example, the decorative body 7 may be formed in a plate shape other than a rectangular plate shape, or the decorative body 7 may be formed in a three-dimensional shape other than a plate shape. Also, the light-emitting unit housing 5 may be formed in a plate shape other than a rectangular plate shape (for example, a circular disc shape, a fan-shaped plate shape), or in a three-dimensional shape other than a plate shape.
