[0014] 1(a) and 1(b) according to an embodiment of the present invention is a device that is held by spectators at a concert venue, for example, and is configured to include a light emitter 3, a housing 5, and a control unit 7. Note that the light emitter 1 may also be used at sporting event venues, theme parks, and other venues other than concert venues. That is, the light emitter 1 may be used by spectators at sporting event venues to cheer on athletes, or by cast members and guests at theme parks to enhance the atmosphere and enjoy the event.

[0015] The housing 5 is configured to include a base end portion (gripping portion) 9 and a tip end portion (light emitting portion) 11. The base end portion 9 is formed, for example, in a cylindrical shape with a bottom, from an opaque synthetic resin that does not transmit light (visible light). The tip end portion 11 is formed, for example, in a cylindrical shape with a bottom, from a transparent or translucent (including colored transparent) synthetic resin that transmits light (visible light). The tip end portion 11 is integrally installed on the base end portion 9 such that the opening of the base end portion 9 mates with the opening of the tip end portion 11.

[0016] The exterior shape of the housing 5 is, for example, a columnar shape such as a long, thin cylinder. One side of the longitudinal direction of the housing 5 is a base end side portion 9, and the other side of the longitudinal direction of the housing 5 is a tip end side portion 11. A closed space is formed inside the housing 5. The shape of the closed space is a long, thin columnar shape (for example, a cylinder) that is slightly smaller than the exterior shape of the housing 5.

[0017] A battery 13 is accommodated and installed inside the base end portion 9 within the closed space of the housing 5. The light emitter 3 is configured to include a red LED, a green LED, and a blue LED. A control unit 7 is also provided inside the base end portion 9 within the closed space of the housing 5. The light emitter 3 is provided near the opening of the base end portion 9.

[0018] The control unit 7 receives power from the battery 13 and causes the light emitter 3 to emit light in various ways. The light emitter 3 emits light (visible light) toward the inside of the tip end portion 11. When the housing 5 with the light emitter 3 emitting light is viewed from the outside of the housing 5, the tip end portion 11 emits light.

[0019] In addition, reference numeral 15 in Figure 1(a) is a switch for turning the power on and off, and reference numeral 17 is a push button switch for changing the light emission mode of the light-emitting body 3, and is a decorative body support member.

[0020] The light emitting device 1 is also provided with a decorative body support member 19. The decorative body support member 19 is separate from the housing 5. The decorative body support member 19 protrudes from the outer surface of the tip end portion 11 (the side surface of the tip end portion 11) and is provided integrally with the tip end portion 11. When the decorative body support member 19 is installed in the tip end portion 11, the decorative body support member 19 supports a decorative body 21 installed outside the tip end portion 11 (see Figure 5).

[0021] As shown in Figures 1 to 4, the decorative body support member 19 is provided with through-holes 25 for passing the string-like portions 23 of the decorative body 21 through. More specifically, the decorative body 21 is formed, for example, in a string-like shape throughout. A plurality of decorative body support members 19 are provided, spaced apart from one another (see Figure 1). The decorative body 21 is configured to be installed and supported by the plurality of decorative body support members 19 by passing through each of the through-holes 25 of the plurality of decorative body support members 19 in turn (see Figure 5).

[0022] The tip portion 11 is formed in a cylindrical shape with a bottom, and includes a side wall portion 27 formed in a tubular (e.g., cylindrical) shape, and a bottom wall portion 29 formed in a curved plate shape or flat plate shape that closes one opening of the side wall portion 27.

[0023] The side wall 27 of the tip end portion 11 is provided with a plurality of through holes 31 for installing the decorative body support member 19. The through holes 31 are provided in the side wall 27, but instead of or in addition to being provided in the side wall 27, the through holes 31 may be provided in the bottom wall 29. In other words, the decorative body support member 19 may be installed in the bottom wall 29.

[0024] The through holes 31 are formed, for example, in a cylindrical shape, and penetrate the side wall portion 27 in the thickness direction. A plurality of decorative body support members 19 are installed in each of the plurality of through holes 31. The through holes 31 and decorative body support members 19 are provided, for example, at predetermined intervals in the direction of extension of the central axis of the side wall portion 27, and are arranged in positions in the circumferential direction of the side wall portion 27 so as to equally divide the outer periphery of the side wall portion 27 (for example, divide it into four parts). The arrangement of the through holes 31 and decorative body support members 19 may be changed to other forms.

[0025] The decorative body support member 19 is transparent or translucent like the distal end portion 11, but may also be opaque like the proximal end portion 9. The surface of the decorative body support member 19 may have a higher light reflectance than the housing 5.

[0026] As shown in Figure 2, the decorative object support member 19 comprises a decorative object support member main body 33 and a leg 35. The leg 35 comprises a cylindrical base end 37 and a truncated cone-shaped tip 39. The leg 35 also has a notch 41.

[0027] The decorative element support member main body 33 is formed, for example, as a thick, flat plate, with one side rectangular and the other semicircular when viewed in the thickness direction. The through-hole 25 is formed, for example, as a cylinder, is provided in the center of the decorative element support member main body 33, and penetrates the decorative element support member main body 33 in the thickness direction. The leg 35 protrudes from the center of one side of the decorative element support member main body 33.

[0028] As shown in Figure 1(c), the decorative body support member 19 is attached to the tip portion 11 using a snap fit. More specifically, while the decorative body support member 19 is being attached to the side wall 27, the tip portions 39 of the legs 35 of the decorative body support member 19 are inserted into the through holes 31 in the side wall 27, causing the legs 35 to elastically deform and reducing the width of the notches 41. Once the decorative body support member 19 has been attached to the side wall 27, the tip portions 39 of the legs 35 have passed through the through holes 31, and the base ends 37 of the legs 35 have inserted into the through holes 31, restoring the legs 35 to their original shape. The side wall 27 of the tip portion 11 is then sandwiched between the main body 33 and the tip portions 39 of the decorative body support member.

[0029] 1(d), the legs 35 of the decorative body support member 19 may be formed in a cylindrical shape. The decorative body support member 19 may then be attached to the side wall 27 of the tip end portion 11 by engaging the legs 35 with the through holes 31 in the side wall 27 of the tip end portion 11 in a tight fit manner.

[0030] 3, the legs 35 of the decorative body support member 19 may be configured with male threads, and the through holes 31 in the side wall portions 27 of the tip end portion 11 may be configured with female threads. Then, the decorative body support member 19 may be installed in the tip end portion 11 by screwing the male threads of the legs 35 into the female threads of the side wall portions 27.

[0031] Furthermore, as shown in Figure 4, not only the decorative body support member main body 33 but the entire decorative body support member 19 may be formed in the shape of a thick flat plate. In the decorative body support member 19 shown in Figure 4, the base end 37 of the leg 35 is formed in the shape of a square prism. When viewed in the thickness direction, the tip end portion of the leg 35 is formed in the shape of an isosceles trapezoid. The through hole 31 in the tip end portion 11 where the decorative body support member 19 shown in Figure 4 is to be installed is formed in the shape of a square prism that is slightly larger than the base end 37 of the leg 35.

[0032] The decorative body support member 19 shown in Fig. 4 is designed to be attached integrally to the tip end portion 11 by a snap fit method, similar to the decorative body support member 19 shown in Fig. 2. When the decorative body support member 19 shown in Fig. 4 is attached to the tip end portion 11, the rectangular prism-shaped base end portion 37 fits into the rectangular prism-shaped through hole 31, preventing the decorative body support member 19 from rotating relative to the tip end portion 11.

[0033] The decorative body 21 is made of, for example, a flexible synthetic resin. The decorative body 21 is transparent or translucent like the distal end portion 11, but may also be opaque like the proximal end portion 9. The surface of the decorative body 21 may have a higher light reflectance than the housing 5. The decorative body 21 may also be formed into a thread-like shape using synthetic fibers, natural fibers, recycled fibers, glass fibers, etc.

[0034] Furthermore, a string-shaped flexible LED may be used as the decorative body 21. In this case, a terminal may be provided at the base end portion 9, and the terminal of the flexible LED may be connected to this terminal, and the flexible LED may be made to emit light in the same manner as the light-emitting body 3 or in a different manner by, for example, a battery 13 in the base end portion 9 and the control unit 7.

[0035] Here, we will explain the light emission of the light-emitting device 1 on which the decorative body 21 is installed. The decorative body 21 is assumed to be transparent or translucent. The surface of the tip portion 11 emits light due to the light emitted from the light-emitting body 3. Then, a portion of the light emitted from the surface of the tip portion 11 passes through the decorative body 21.

[0036] The decorative body 21 attached to the light-emitting device 1 is integrated as a whole with the light-emitting device 1, but a part of the decorative body 21 attached to the light-emitting device 1 (for example, a part extending from the light-emitting device 1) may be able to move or change position relative to the light-emitting device 1.

[0037] The light emitting device 1 is configured with a decorative body support member 19 that supports a decorative body 21 that is placed on the outside of the tip end portion 11. By placing the decorative body 21 on the outside of the tip end portion 11 via the decorative body support member 19, not only does it emit light, but the decorative effect of the decorative body 21 is obtained, making it possible to differentiate the light emitting mode of the light emitting device 1 and further enhancing the presentation effect. Furthermore, the decorative body support member 19 may also be designed to exert a decorative effect, just like the decorative body 21.

[0038] Furthermore, the light emitting device 1 is provided with a through-hole 25 for passing the string-like portion of the decorative body 21 through the decorative body support member 19. This simplifies the configuration of the decorative body support member 19, while allowing the decorative body 21 to be firmly attached to the housing 5 in a manner that makes it difficult for it to come off the housing 5.

[0039] Next, a modified example of the light emitting device 1a will be described. The light emitting device 1a is different from the light emitting device 1 in the shape of the decorative body support member (see Figs. 6 and 7) 19, but is otherwise configured in the same manner as the light emitting device 1.

[0040] The decorative body support member 19 shown in Figures 6 and 7 is also arranged to be installed on the outside of the tip end portion 11. In the embodiment shown in Figures 6 and 7, the decorative body support member 19 is configured so that its position relative to the tip end portion 11 can be changed.

[0041] More specifically, the tip end portion 11 is provided with a protrusion 45 having a cylindrical through-hole 43. The decorative body support member 19 is configured with an annular main body portion 47 having a through-hole 25 and a pair of protrusions 51 having cylindrical through-holes 49. The decorative body support member 19 is attached to the tip end portion 11 by a cylindrical pin 53.

[0042] That is, the protrusion 45 is inserted between the pair of protrusions 51 so that the central axis of the through hole 43 and the central axis of the pair of through holes 49 are aligned with each other. Next, the pin 53 is inserted into the through hole 43 and the pair of through holes 49. The pin 53 is inserted into the through hole 43 and the pair of through holes 49 in an interference fit, clearance fit, or center fit manner. To explain further using an example, the pin 53 is inserted into the through hole 49 with a clearance fit, and into the through hole 43 with an interference fit.

[0043] As a measure to prevent the pin 53 inserted into the through hole 43 and the pair of through holes 49 from coming out, the pin 53 may be provided with a flange 55 and a tip 57, as shown in Fig. 7. The tip 57 is formed in a truncated cone shape so that the pin 53 can be inserted into the through hole 43 and the pair of through holes 49. The pin 53 is also provided with a notch 59 so that the pin 53 can be inserted into the through hole 43 and the pair of through holes 49. The pin 53 may be configured to be installed in a manner similar to that shown in Fig. 1(c) etc.

[0044] In the light emitting device 1a, the decorative body support member 19 installed on the outside of the tip end portion 11 is configured so that its position relative to the tip end portion 11 can be changed. This increases the degree of freedom when installing the decorative body 21. In other words, by changing the position of the decorative body support member 19, the decorative body can be installed in a wider variety of ways.

[0045] In the light emitting device 1a, the central axes of the pins 53 and the like are twisted relative to the central axis of the side wall 27 of the tip end portion 11. In addition, the central axis of the through hole 25 of the decorative body support member 19 extends parallel to the central axis of the side wall 27 of the tip end portion 11 in the state shown in Figures 6(a) and 6(b). Furthermore, the extension direction of the central axis of the through hole 25 of the decorative body support member 19 changes around the central axis of the pin 53.

[0046] Here, as shown in Fig. 8, the extension direction of the central axis of the through hole 25 of the decorative body support member 19 may be perpendicular to the extension direction of the central axis of the through hole 25 shown in Figs. 6(a) and (b), or may extend at an intersecting angle other than a right angle. In the state shown in Fig. 8, the central axes of the pins 53 etc. extend parallel to the central axis of the side wall portion 27 of the tip side portion 11.

[0047] 6 and 8, the decorative body support member 19 is designed to rotate only around one central axis (the central axis of the pin 53). However, the decorative body support member 19 may also be designed to rotate around one axis (two axes whose extension directions intersect each other) relative to the tip end portion 11. For example, the tip end portion 11 may support the decorative body support member 19 via a spherical bearing.

[0048] Next, a modified light emitting device 1b will be described with reference to Figures 9 and 10. The light emitting device 1b differs from the light emitting device 1 in that it has a decorative body support part 61 instead of the decorative body support member 19, but in other respects it is configured the same as the light emitting device 1. The decorative body support part 61 is formed integrally with the tip end part 11, and protrudes from the outer surface of the tip end part 11 (for example, the side wall part 27), and is provided integrally with the tip end part 11. The decorative body support part 61 is then designed to support the decorative body 21 that is placed outside the tip end part 11.

[0049] Similar to the decorative body support members 19, multiple decorative body support portions 61 are also provided and arranged. Each decorative body support portion 61 also has a through hole 25. In the embodiment shown in FIG. 9, the central axis of the through hole 25 is twisted relative to the central axis of the side wall portion 27 of the tip end portion 11. In the embodiment shown in FIG. 10, the central axis of the through hole 25 extends parallel to the central axis of the side wall portion 27 of the tip end portion 11. However, the central axis of the through hole 25 may extend in other directions.

[0050] In the light emitting device 1b, the ornamental body support part 61 is integrally molded with the tip end part 11. This eliminates the need to manufacture the ornamental body support member 19 separately from the housing 5, thereby reducing the number of steps required to manufacture the light emitting device 1b.

[0051] Next, a modified decorative body support member 19 and tip portion 11 will be described with reference to Figures 11 to 15. The leg 35 of the modified decorative body support member 19 is configured with a leg main body 63 and a protrusion 65. The leg main body 63 is formed in a cylindrical shape. The protrusion 65 is formed in a flat plate shape with a predetermined thickness. When viewed in the thickness direction, the protrusion 65 is formed in a trapezoid shape with one oblique side perpendicular to the upper and lower bases.

[0052] There are multiple (for example, four) protrusions 65, which protrude from the leg main body 63 at the tip end of the leg main body 63 (the end opposite the decorative body support member main body 33). The protrusions 65 are positioned so as to evenly distribute the outer periphery of the leg main body 63. The thickness direction of the protrusions 65 coincides with the circumferential direction of the leg main body 63. The upper base of the protrusions 65 is located at the tip of the leg main body 63, and the lower base of the protrusions 65 is located on the decorative body support member main body 33 side.

[0053] The through hole 31 provided in the tip end portion 11 is configured with a cylindrical through hole main body 67 and multiple (for example, four) recesses 69. Then, when the decorative body support member 19 shown in Figure 12 is ready to be installed in the tip end portion 11, the decorative body support member 19 is moved relative to the tip end portion 11. In this movement, the decorative body support member 19 is moved to the left in Figure 12.

[0054] As a result of this movement, the tip of the leg 35 (including the protrusion 65) passes through the through-hole 31. When the tip of the leg 35 has passed through, the part of the leg 35 (the part without the protrusion 65) is inside the through-hole 31. Next, when the decorative body support member 19 is rotated by a predetermined angle (for example, 45°), it reaches the state shown in Figure 14. In this state, the flesh of the tip portion 11 of the housing 5 is sandwiched between the decorative body support member main body 33 and the protrusion 65, and the decorative body support member 19 is installed in the tip portion 11.

[0055] 15, a protrusion 71 may be provided on the tip end portion 11 to make it difficult for the decorative body support member 19 installed in the tip end portion 11 to rotate, making it difficult for the decorative body support member 19 to come off the tip end portion 11. Furthermore, although not shown, a recess may be provided in the tip end portion 11, and a protrusion may be provided on the decorative body support member 19, so that the protrusion fits into the recess, making it difficult for the decorative body support member 19 installed in the tip end portion 11 to rotate.

[0056] Next, a modified light emitting device 1c will be described with reference to Figures 16 to 18. In the modified light emitting device 1c, the shape of the decorative body support member 19 is different from that of the light emitting device 1, but other points are configured the same as the light emitting device 1.

[0057] The luminous device 1c shown in Figs. 16 to 18 differs from the luminous device 1 in that an ornament support member (see Figs. 16 to 18) 19 is configured similarly to the luminous device 1 in other respects.

[0058] The decorative body support member 19 of the light emitting device 1c is configured with a base end (leg) 73 that directly engages with the tip end portion 11 when installed in the tip end portion 11. The decorative body support member 19 of the light emitting device 1c is also configured with a tip end portion 75 that is provided at the tip of the base end portion 73 and protrudes from the tip of the base end portion 73 in a direction intersecting the protruding direction of the base end portion 73.

[0059] The light emitting device 1c has a plurality of decorative body support members 19 spaced apart from one another, and is configured so that the string-like portion of the decorative body 21 is wrapped around the base end 73. To explain further, for example, the decorative body 21 is formed in a string shape. The decorative body 21 is wound around each of the base ends 73 of the plurality of decorative body support members 19 in turn, and is installed and supported by the plurality of decorative body support members 19.

[0060] In the decorative object support member 19 shown in Figure 16, the tip portion 75 is formed in a spherical crown shape (it can also be disk-shaped, etc.). The central axis of the base end portion 73 and the central axis of the tip portion 75 are aligned with each other. As a result, when viewed from the side, the decorative object support member 19 shown in Figure 16 looks like an umbrella or mushroom. Furthermore, the decorative object support member 19 shown in Figure 16 is attached to the tip portion 11 in the form shown in Figures 1(c)(d), 11, and 15, but it may also be attached to the tip portion 11 by a male screw, as shown in Figure 17.

[0061] In the decorative body support member 19 shown in Figure 18, the tip portion 75 protrudes in only one direction from the tip of the base portion 73. The decorative body support member 19 shown in Figure 18 is also designed to be installed in the tip portion 11 in the same manner as the decorative body support members 19 shown in Figures 16 and 17.

[0062] The light emitting device 1c is provided with a plurality of decorative body support members 19, and is configured so that the string-like portion of the decorative body 21 is wrapped around the base end portion 73 of the decorative body support members 19. This allows the decorative body 21 to be quickly replaced, etc.

[0063] The luminous device 1d shown in Figures 19 and 23(a) differs from the luminous device 1 shown in Figure 1 etc. mainly in the shape of the tip end portion 11 and the installation mode of the decorative body 21, but in other respects it is configured in the same way as the luminous device 1. That is, the tip end portion 11 of the luminous device 1d is provided with a protrusion 77 that constitutes the decorative body 21 instead of the decorative body support member 19.

[0064] The protrusion 77 is provided to vary the light emission pattern in the tip portion 11 (light emission pattern due to differences in locations in the tip portion 11) to enhance the decorative effect. The protrusion 77 is, for example, molded integrally with the tip portion 11, and protrudes from a portion of the outer surface of the tip portion 11 and is provided integrally with the tip portion 11. As shown in Figure 23(b), the protrusion 77 may be molded separately from the tip portion 11 and then provided integrally with the tip portion 11. When the protrusion 77 (decorative body 21) is viewed in this protruding direction, it has the shape of a predetermined character, figure, symbol, etc.

[0065] Figures 19 and 23(b) show decorative bodies 21 in the form of letters and in the form of jewels. More specifically, as shown in Figure 23(b), the decorative body 21 is comprised of a decorative body main body 81 and protrusions 83. The decorative body main body 81 is shaped like letters or jewels and is primarily responsible for the decorative effect. Examples of jewel-shaped shapes include polygonal truncated pyramids such as low regular polygonal truncated pyramids, low circular truncated cones, and low elliptical truncated cones. Examples of regular polygonal truncated pyramids include three-dimensional shapes such as regular triangular truncated pyramids, tetragonal truncated pyramids, pentagonal truncated pyramids, hexagonal truncated pyramids, heptagonal truncated pyramids, octagonal truncated pyramids, and decagonal truncated pyramids. Examples of jewel-shaped shapes include polygonal pyramids such as low regular polygonal pyramids, low cones, and low elliptical cones.

[0066] The protrusion 83 protrudes from the back surface of the decorative body main body 81 (the surface that contacts the tip end portion 11 when the decorative body 21 is placed on the tip end portion 11) in the protruding direction of the protrusion 77 (thickness direction of the decorative body main body 81). When the gem-shaped decorative body main body 81 is formed in a truncated pyramid shape, such as a polygonal truncated pyramid, the protrusion 83 protrudes from the bottom surface of the truncated pyramid (one side in the height direction of the truncated pyramid, the side with the larger area). When the gem-shaped decorative body main body 81 is formed in a cone shape, such as a circular cone, the protrusion 83 protrudes from the bottom surface of the cone.

[0067] The tip end portion 11 is provided with a through-hole (not shown in FIG. 23), and the protrusions 83 fit into the through-hole, allowing the decorative body 21 to be integrally attached to the tip end portion 11 using a snap fit or interference fit. It is desirable that multiple (for example, two) protrusions 83 protrude from the decorative body main body 81. This prevents the decorative body 21 attached to the tip end portion 11 from rotating relative to the tip end portion 11.

[0068] Furthermore, the protrusions 77 constituting the decorative body 21 are provided in multiple numbers on one light emitting device 1d (for example, the tip end portion 11). Furthermore, the decorative body 21 may be designed to be easily attached and detached to the light emitting device 1d (for example, the tip end portion 11). In other words, the decorative body 21 may be designed to be easily detached from the light emitting device 1d when it is attached to the light emitting device 1d, and the decorative body 21 may be designed to be easily attached to the light emitting device 1d when it is not attached to the light emitting device 1d.

[0069] For example, the protrusion 83 is formed in a cylindrical shape, and the through-hole in the tip portion 11 into which the protrusion 83 fits is also formed in a cylindrical shape. The inner diameter of the through-hole in the tip portion 11 is set to be slightly smaller than the outer diameter of the protrusion 83. In addition, a slot (notch) is provided in the protrusion 83. When viewed in the height direction of the cylindrical protrusion 83 (the extension direction of the central axis), the slot is formed in an "X" or "Y" shape.

[0070] When the decorative body 21 is in the process of being installed in the light emitting device 1d, the protrusion 83 is pressed against the wall surface of the through hole in the tip end portion 11, causing it to elastically deform. This elastic deformation reduces the width dimension of the slot and the outer diameter of the protrusion 83. When the decorative body 21 has been installed in the light emitting device 1d, the protrusion 83 has recovered to a certain extent. However, since the protrusion 83 has not completely recovered, the protrusion 83 is still pushing into the through hole in the tip end portion 11 with an urging force. In other words, the protrusion 83 is pressing against the wall surface of the through hole in the tip end portion 11.

[0071] This configuration allows the decorative body 21 to be easily attached to and detached from the light emitting device 1d (for example, the tip end portion 11). After the decorative body 21 has been attached to the light emitting device 1d, even if the light emitting device 1d is held and shook by hand, the biasing force of the protrusions 83 prevents the decorative body 21 from coming off the light emitting device 1d.

[0072] The decorative body 21 (protrusion 77) shown in Figures 19 and 23 is transparent, just like the tip portion 11, but the decorative body 21 may be opaque, or the decorative body 21 may be transparent and of a different color than the tip portion 11. Furthermore, the light transmittance of the decorative body 21 and the light transmittance of the tip portion 11 may be different from each other. For example, the light transmittance of the decorative body 21 may be lower than the light transmittance of the tip portion 11. Furthermore, the light reflectance of the surface of the decorative body 21 (protrusion 77) may be higher than the reflectance of the housing 5.

[0073] 19 and 23, the decorative body 21 is configured with a protrusion 77, but instead of or in addition to the decorative body 21 being configured with a protrusion 77, the decorative body 21 may be configured with a recess. The recess is recessed from the outer surface of the tip side portion 11 toward the inside of the tip side portion 11. The recess may also be recessed from the inner surface of the tip side portion 11 toward the outside of the tip side portion 11. The recess is provided in the tip side portion 11 by, for example, integral molding.

[0074] In the light emitting device 1d, a protrusion 77 (decorative body 21) is provided at the tip end portion 11 of the housing 5 to change the light emission mode at the tip end portion 11. This allows the light emission mode of the tip end portion 11 to be changed, further enhancing the dramatic effect.

[0075] In addition, in the light emitting device 1d, a decorative body support member 19 may be provided instead of or in addition to the protrusion 77. Also, in the light emitting device 1 etc., a decorative body support member 19 and a protrusion 77 may be provided instead of or in addition to the protrusion 77.

[0076] The side wall portion 27 of the tip portion 11 of the light emitting device 1d is formed in a hexagonal tubular shape (for example, a regular hexagonal tubular shape) as shown in Fig. 20. The side wall portion 27 of the tip portion 11 of the light emitting device 1d may be formed in a polygonal tubular shape such as a cylindrical shape, a pentagonal tubular shape (for example, a regular pentagonal tubular shape), an octagonal tubular shape (for example, an octagonal pentagonal tubular shape), or other tubular shape such as a bow-shaped tubular shape as shown in Fig. 21. Similarly, the side wall portion 27 of the tip portion 11 of the light emitting device 1 shown in Fig. 1 etc. may be formed in a shape such as a hexagonal tubular shape.

[0077] 19 and 20, the protrusions 77 are provided on the flat outer surface of the side wall 27, but as shown in Fig. 21, they may be provided on the curved outer surface of the side wall 27. Furthermore, instead of or in addition to providing the protrusions 77 on the outer surface of the side wall 27, they may be provided on the inner surface of the side wall 27.

[0078] 22, instead of or in addition to providing the decorative body support member 19 or decorative body support portion 61 in the tip end portion 11, a plurality of through holes 79 may be provided in the tip end portion 11, penetrating the flesh of the tip end portion 11. Then, the decorative body 21 may be attached to the tip end portion 11 by passing the string-like decorative body 21 through the through holes 79.

[0079] Although the present embodiment has been described above, it is not limited to this, and various modifications are possible within the scope of the present embodiment. For example, the protruding height of the decorative body main body 81 may be increased to form a three-dimensional shape like the decorative body support member 19. In other words, the cross-sectional area of ​​the decorative body main body 81 (the area of ​​the cross section taken along a plane perpendicular to the protruding direction of the decorative body main body 81) may increase or decrease depending on the protruding direction of the decorative body main body 81.
