[0020] The light emitting devices 1, 1a to 1q (see FIGS. 1, 3 to 6, and 8 to 18) according to the embodiments of the present invention are intended to be held by spectators at concert venues, for example, and are configured to include a base 3 and a light emitting unit 5, as shown in FIG. 1(a) and other figures. The light emitting devices 1, 1a to 1q may also be used at sporting event venues, theme parks, and other venues other than concert venues. That is, the light emitting devices 1, 1a to 1q 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.

[0021] As shown in Fig. 22, the base 3 is configured with a control unit (for example, a control unit configured with a CPU and a memory) 7, a power supply installation unit (battery installation unit) 9 in which a power supply (battery) is installed, and a housing 11. The control unit 7 and the power supply installation unit 9 are provided inside the housing 11. An operation unit (operation switch) 13 is provided on the housing 11. By operating the operation unit 13, the power of the light-emitting devices 1, 1a to 1q is turned on and off, and the light emission mode of the light-emitting unit 5 (for example, the light emission color and brightness) is changed.

[0022] The light-emitting unit 5 is elastic (flexible) and formed in a thin, linear shape, extending from the base 3. The end (tip) of the light-emitting unit 5 opposite the end on the base 3 side in the longitudinal direction (extension direction) (the end connected to the base 3; the base end) is a free end. The light-emitting unit 5 receives a supply of power from a power source installed in the power source installation unit 9, and emits light (e.g., visible light) under the control of the control unit 7. The light-emitting unit 5 is composed of, for example, a flexible LED.

[0023] More specifically, the light-emitting unit 5 is formed, for example, in a string or strip shape. The cross-section (cross-section taken along a plane perpendicular to the longitudinal direction) of the string-shaped light-emitting unit 5 is, for example, a circle, a regular polygon, or a shape that approximates a circle or a regular polygon. Furthermore, in the string-shaped light-emitting unit 5, the ratio of the horizontal dimension to the vertical dimension of the cross-sectional shape is "1" or a value that approximates "1" (for example, greater than or equal to "1" and less than "2").

[0024] In the strip-shaped light-emitting portion 5, the cross-section (cross-section taken along a plane perpendicular to the longitudinal direction) is rectangular in shape, with the horizontal dimension and the vertical dimension being significantly different, or elliptical in shape, with the short axis and the long axis being significantly different. Also, in the strip-shaped light-emitting portion, the ratio of the horizontal dimension to the vertical dimension of the cross-section is, for example, between 2 and 100; or between 2 and 20.

[0025] The cross-sectional shape of the light-emitting section 5 may change in the longitudinal direction of the light-emitting section 5. For example, the cross-sectional shape may be circular at one longitudinal end of the light-emitting section 5, and elliptical at the other longitudinal end of the light-emitting section 5, with the minor axis dimension value and the major axis dimension value being significantly different. Then, the cross-sectional shape may gradually change from circular to elliptical between one longitudinal end and the other longitudinal end.

[0026] As shown in FIG. 2(a), the light-emitting unit 5 is elongated by arranging a plurality of light-emitting bodies (e.g., LEDs) 15 in a row. The plurality of light-emitting bodies 15 are connected in parallel. More specifically, the light-emitting unit 5, which is made up of an elongated flexible LED, is configured with two conductors (two flexible conductors) 17, 19 and the plurality of LEDs 15. The two conductors 17, 19 are configured to supply power to each of the plurality of LEDs 15. The spacing between the plurality of LEDs 15 is minimized.

[0027] The plurality of LEDs 15 are arranged between the two conductors 17, 19 in the longitudinal direction of the two conductors 17, 19 and are connected in parallel by the two conductors 17, 19. The cathodes of the plurality of LEDs 15 are connected to the conductor 17, and the anodes of the plurality of LEDs 15 are connected to the conductor 19.

[0028] The two conductive wires 17, 19 extend from the base 3 substantially parallel to each other. In the elongated flexible LED 5, the two conductive wires 17, 19 and the plurality of LEDs 15 are covered with an elastic synthetic resin 21 (see FIG. 1, etc.). The synthetic resin 21 is, for example, semi-transparent, so as to diffuse and transmit the light emitted by the LEDs 15. The synthetic resin 21 may also be made of a transparent synthetic resin. Furthermore, for example, the outer shape of the synthetic resin 21 corresponds to the outer shape of the light-emitting unit 5.

[0029] Electric power for emitting light from the LED 15 is supplied through the two conductors 17 and 19 under the control of the control unit 7. In FIG. 1(a), reference numeral 23 denotes a power supply, and reference numeral 25 denotes a resistor.

[0030] In the light emitting devices 1, 1a to 1q, the light emitting unit 5 is formed to be elastic and elongated, extending from the base 3 with a free end at the tip. This allows the light emitting unit 5 to emit light while changing into various shapes. When used in a concert hall or the like, the light emitting unit 5 can emit light in a manner that is more suited to the situation.

[0031] In the light emitting device 1 shown in Fig. 1(a), the outer shape of the housing 11 of the base 3 is cylindrical, but the outer shape of the housing 11 may be a shape other than cylindrical. For example, as in the light emitting device 1a shown in Fig. 1(b), the outer shape of the housing 11 may be a rectangular parallelepiped.

[0032] 1(a), the light emitting device 1 is configured to emit light in a uniform manner in the longitudinal direction (for example, in a manner in which the color and brightness do not change in the longitudinal direction). In contrast, the light emitting device 1a shown in FIG. 1(b) may be configured so that the light emitting manner of the light emitting device 5 changes in the longitudinal direction of the light emitting device 5.

[0033] In the light-emitting device 1a, the light-emitting section 5 is configured so that it can emit light in different light emission modes for each of the plurality of sections 5A to 5I in the longitudinal direction. For example, the section 5A emits light in red, the section 5B emits light in orange, the section 5C emits light in yellow, the section 5D emits light in green, the section 5E emits light in blue, the section 5F emits light in indigo, the section 5G emits light in purple, and the sections 5H and 5I emit light in white.

[0034] The light-emitting unit 5 of the light-emitting device 1a is configured to emit white light using a red LED, a green LED, and a blue LED. For example, in the configuration shown in FIG. 2(a), multiple LEDs 15 are arranged in the following order: red LED, green LED, blue LED, red LED, etc. As shown in FIG. 2(b), the light-emitting unit 5 of the light-emitting device 1a is covered with tubes 27 (27A-27I) that transmit light of a predetermined color. Tube 27A transmits only red light, tube 27B transmits only orange light, and tube 27I transmits white light. This allows the light-emitting unit 5 shown in FIG. 2(b) to change the emitted color in its longitudinal direction.

[0035] 2(b) may be omitted. In the configuration shown in FIG. 2(a), for example, a predetermined number of red LEDs may be arranged in a row, followed by a predetermined number of green LEDs, and then a predetermined number of blue LEDs. This allows the light-emitting unit 5 to emit light in different light emission modes at different positions along its length.

[0036] The light-emitting unit 5 of the light-emitting device 1a may be configured as shown in FIG. 2(c). The portion 5a of the light-emitting unit 5 shown in FIG. 2(c) is configured as shown in FIG. 2(a), and the plurality of LEDs 15 is configured only with red LEDs. Similarly, the plurality of LEDs 15 in the portion 5b is configured only with green LEDs, and the plurality of LEDs 15 in the portion 5c is configured only with blue LEDs. The portions 5a, 5b, and 5c extend close to each other. The brightness of each of the portions 5a, 5b, and 5c can be changed independently. By appropriately changing the brightness of the portions 5a, 5b, and 5c, the light-emitting unit 5 can change the emitted color along its entire length.

[0037] The light-emitting unit 5 of the light-emitting device 1a may also be configured as shown in FIG. 2(d). Each of the portions 5a1 to 5a7 of the light-emitting unit 5 shown in FIG. 2(d) is configured as shown in FIG. 2(a), and the multiple LEDs 15 are configured solely with red LEDs. The portions 5a1 to 5a7 are arranged in order in the longitudinal direction of the light-emitting unit 5 and are capable of emitting light independently of each other. Similarly, the multiple LEDs 15 of the portions 5b1 to 5b7 are configured solely with green LEDs, and the portions 5b1 to 5b7 are arranged in order in the longitudinal direction of the light-emitting unit 5 and are capable of emitting light independently of each other. The multiple LEDs 15 of the portions 5c1 to 5c7 are configured solely with blue LEDs, and the portions 5c1 to 5c7 are arranged in order in the longitudinal direction of the light-emitting unit 5 and are capable of emitting light independently of each other. This allows the light-emitting unit 5 to change the emitted color in the longitudinal direction.

[0038] In addition to the light emitting device 1a shown in FIG. 1(b), other light emitting devices such as the light emitting device 1 may be configured so that the light emission state of the light emitting part 5 changes in the longitudinal direction of the light emitting part 5.

[0039] The light emitting device 1b shown in FIG. 3 and the light emitting device 1c shown in FIG. 4 are configured with an installation body 29. The light emitting devices 1b, 1c, etc. configured with the installation body 29 are intended to be used as clothing, accessories, round fans, folding fans, towels, hand towels, handkerchiefs, and flags (a flag body made of fabric, and a rod-shaped body on which the flag body is installed). Examples of clothing that can be displayed include clothing (clothing such as tops and bottoms), headgear such as hats and headbands, gloves, footwear such as socks and shoes, and wristbands. Examples of accessories that can be displayed include wigs, wings on the back, hair clips, scarves, necklaces, friendship bracelets, wristbands, etc.

[0040] The installation body 29 is configured to include at least one of a fabric portion 29A made of fabric and a transparent portion 29B made of, for example, synthetic resin, which is elastic and formed in a plate shape.

[0041] The installation body 29 is provided with a base installation section 31 and a light-emitting section installation section 33. The base 3 is installed on the base installation section 31. The light-emitting section 5 is installed on the light-emitting section installation section 33. The base installation section 31 and the light-emitting section installation section 33 are provided on at least one of the fabric section 29A and the transparent section 29B.

[0042] The base 3 and the light emitting unit 5 installed on the installation body 29 are protected by the installation body 29 from external forces acting on the base 3 and the light emitting unit 5 .

[0043] Explaining further, the installation body 29 of the light emitting device 1b shown in Fig. 3 is configured to include a fabric portion 29A. In the light emitting device 1b, a light emitting unit installation portion 33 is provided in the fabric portion 29A. The light emitting unit 5 formed in a linear shape is installed in the light emitting unit installation portion 33 in a manner that is woven into the fabric portion 29A.

[0044] A more detailed explanation will be given below. The outer diameter of the elongated light emitting portion 5 is, for example, about 1 mm to 2 mm, which is larger than the outer diameter of the thread that constitutes the fabric portion 29A. Therefore, the light emitting portion 5 is not woven into the fabric portion in the same manner as the thread that constitutes the fabric portion 29A.

[0045] As shown in Fig. 3(c), the light emitting units 5 penetrate the fabric region 29A in the thickness direction and are installed on the light emitting unit installation portion 33 so as to appear alternately on both sides of the fabric region 29A in the thickness direction. If the fabric of the fabric region 29A is woven, the pitch of the holes in the fabric region 29A through which the light emitting units 5 penetrate is larger than the pitch of the warp and weft threads in the grain of the fabric region 29A. If the fabric of the fabric region 29A is knitted, the pitch of the holes in the fabric region 29A through which the light emitting units 5 penetrate is larger than the pitch of the mesh of the fabric region 29A.

[0046] In the light emitting device 1b shown in Fig. 3, a base mounting part 31 is provided in the fabric part 29A. The base 3 formed in a predetermined shape is mounted on the base mounting part 31 in such a manner that it is housed in a pocket 35 provided in a part of the fabric part 29A, as shown in Fig. 3(b).

[0047] Furthermore, in the light emitting device 1b, the fabric portion 29A is formed in a rectangular shape, so that the light emitting device 1b can be used as a towel or hand towel. Reference numeral 37 in FIG. 3(b) denotes a snap button. When the snap button 37 is released, the opening of the pocket 35 is wide open. In this state, the base 3 can be inserted and removed from the pocket 35. When the snap button 37 is closed, the opening of the pocket 35 narrows, so that the base 3 housed in the pocket 35 does not come out of the pocket 35.

[0048] In the light emitting device 1b, the light emitting part 5 extends linearly in the width direction of the fabric part 29A at one end in the longitudinal direction of the fabric part 29A. As shown by the two-dot chain line 39 in Fig. 3(a), the light emitting part 5 may be provided in another part of the fabric part 29A (for example, the center) in a shape other than a linear shape (for example, an ellipse).

[0049] In addition, in the light-emitting device 1b, the fabric portion 29A is opaque, but the fabric portion 29A may be semi-transparent or otherwise made to transmit some of the light emitted by the light-emitting unit 5. Furthermore, the fabric portion 29A may be made of a thread that reflects the light emitted by the light-emitting unit 5.

[0050] The installation body 29 of the light emitting device 1c shown in Fig. 4 is configured to include a fabric portion 29A and a transparent portion 29B. In the light emitting device 1c, the light emitting unit installation portion 33 and the base installation portion 31 are provided in the transparent portion 29B. The transparent portion 29B is formed in a cylindrical shape and is provided at one end in the longitudinal direction of the rectangular installation body 29. The central axis of the cylinder of the transparent portion 29B extends over the entire width of the rectangular installation body 29.

[0051] The base 3 and the linearly formed light-emitting unit 5 are housed inside the cylindrically formed transparent portion 29B, so that the base 3 is installed in the base installation portion 31 and the light-emitting unit 5 is installed in the light-emitting unit installation portion 33. When the base 3 is installed in the base installation portion 31 and the light-emitting unit 5 is installed in the light-emitting unit installation portion 33, the base 3 is located at one end in the extension direction of the central axis of the tube of the transparent portion 29B. Furthermore, when the base 3 is installed in the base installation portion 31 and the light-emitting unit 5 is installed in the light-emitting unit installation portion 33, the light-emitting unit 5 extends over almost the entire length of the width direction of the installation body 29 in the extension direction of the central axis of the tube of the transparent portion 29B.

[0052] The fabric portion 29A and the transparent portion 29B are connected to each other at the connection point 41 shown in Fig. 4(a). In the light emitting device 1c shown in Fig. 4, the installation body 29 is formed in a rectangular shape, so that the light emitting device 1c can be used as a towel or hand towel. Also, the reference numeral 37 in Fig. 4 denotes a snap button.

[0053] When the snap button 37 is released, the area in the transparent portion 29B where the base 3 is placed is wide open (see FIG. 4(b)). In this state, the base 3 can be inserted into or removed from the transparent portion 29B. When the snap button 37 is closed, the area in the transparent portion 29B where the base 3 is placed is narrowed, so that the base 3 housed in the transparent portion 29B does not come out of the transparent portion 29B.

[0054] In the light emitting devices 1b and 1c, the installation body 29 has at least one of a fabric portion 29A and a transparent portion 29B, and the light emitting unit installation portion 33 on which the light emitting unit 5 is installed is provided in at least one of the fabric portion 29A and the transparent portion 29B. This allows the light emitting unit 5, which is made up of a flexible LED 5, to be protected from external forces applied to the light emitting unit 5 by the fabric portion 29A and the transparent portion 29B. Furthermore, the light emitted by the light emitting unit 5 is scattered, refracted, or reflected by the fabric portion 29A and the transparent portion 29B, allowing the light emitting device to emit light in a manner that is even more suited to the environment.

[0055] 22, the light emitting devices 1, 1a to 1q are provided with vibration detection sensors 43. The vibration detection sensors 43 are provided on the base 3 or the installation body 29. In the embodiment shown in FIG. 22, the vibration detection sensors 43 are installed inside the housing 11.

[0056] In the light emitting devices 1, 1a to 1q, the light emitting unit 5 is configured to emit light under the control of the control unit 7 in response to vibrations detected by the vibration detection sensor 43. The vibration detection sensor 43 is configured to detect vibrations occurring in the light emitting devices 1, 1a to 1q (the base 3 or the installation body 29).

[0057] More specifically, the vibration detection sensor 43 transmits the detected vibrations of the light-emitting devices 1, 1a-1q to the control unit 7 as an electric signal. The control unit 7 is provided with a vibration analysis unit and a light emission control unit. The vibration analysis unit determines whether the vibrations detected by the vibration detection sensor 43 are within a predetermined frequency range (for example, within a range of 1 Hz to 20 Hz). The vibration analysis unit also determines whether the vibrations within the predetermined frequency range have been detected for a predetermined period of time (for example, whether they have been detected for a period of 1 second or more and 20 seconds or less).

[0058] When the vibration analysis unit determines that vibrations within the predetermined range of frequencies have been detected for the predetermined period of time, the light emission control unit causes the light emitting unit 5 to emit light.

[0059] Note that instead of or in addition to the above-mentioned frequency and time, the acceleration applied to the light-emitting devices 1, 1a to 1q may be used. That is, suppose that a signal sent from the vibration detection sensor 43 detects that a predetermined magnitude of acceleration (for example, an acceleration magnitude in the range of 0.1 G to 10 G) has been applied to the light-emitting devices 1, 1a to 1q. At this time, the control unit 7 may be configured to cause the light-emitting unit 5 to emit light.

[0060] Furthermore, instead of or in addition to the frequency, time, and acceleration described above, the amplitude of the light-emitting devices 1, 1a to 1q may be used. That is, it is assumed that the control unit 7 determines, based on the signal sent from the vibration detection sensor 43, that the value of the amplitude caused by the vibration of the light-emitting devices 1, 1a to 1q is within a predetermined range. At this time, the control unit 7 may be configured to cause the light-emitting unit 5 to emit light.

[0061] Furthermore, light-emitting unit 5 may be configured to change the manner of light emission, such as by changing the color of light emitted, depending on at least one of the frequency, time, acceleration, and amplitude of vibration detected by vibration detection sensor 43. For example, when the amplitude value of vibration detected by vibration detection sensor 43 is within a range between a first value and a second value, control unit 7 may cause light-emitting unit 5 to emit light in yellow. Furthermore, when the amplitude value of vibration detected by vibration detection sensor 43 is within a range between a second value and a third value, control unit 7 may cause light-emitting unit 5 to emit light in red. Note that the relationship among the first value, the second value, and the third value is assumed to be first value<second value<third value.

[0062] The light emitting devices 1, 1a to 1q are configured so that the light emitting unit 5 emits light in response to vibrations detected by the vibration detection sensor 43. As a result, when used at a concert venue, the manner in which the light is emitted by the light emitting unit 5 can be easily changed by holding the light emitting devices 1, 1a to 1q in one's hand and changing the type of vibration applied to the light emitting devices 1, 1a to 1q.

[0063] In the light emitting device 1d shown in Fig. 5, the installation body 29 is configured to include an installation body main body 29C and an installation body attachment 29D. The installation body attachment 29D is provided with a base installation part 31 and a light emitting part installation part 33. The installation body attachment 29D is configured to be easily attached to and detached from the installation body main body 29C. The light emitting device 1d is intended to be used, for example, as a towel or hand towel.

[0064] The installation body main body 29C is formed into a rectangular shape using, for example, fabric. The installation body attachment 29D is made of a transparent or transparent plate-shaped synthetic resin and is flexible. The base 3 and the light-emitting unit 5 are attached to the installation body attachment 29D by being sandwiched between two elongated rectangular plate-shaped members 45 that make up the installation body attachment 29D.

[0065] The installation body appendage 29D is configured to be attached to the installation body main body using a hook-and-loop fastener 47 such as Velcro (registered trademark), a line fastener such as a zipper, or a point fastener such as a snap button, etc. This makes the installation body appendage 29D detachable (removable) from the installation body main body 29C.

[0066] To explain further, in an installed state in which the installation body appendage 29D is installed on the installation body main body 29C (see FIGS. 5(a) to (c)), the installation body appendage 29D can be easily removed with bare hands from the installation body main body 29C. In the above-mentioned installed state, the base 3 is installed on the base installation part 31 of the installation body appendage 29D, and the light-emitting part 5 is installed on the light-emitting part installation part 33. In addition, in the above-mentioned installed state, the installation body appendage 29D is provided at one end of the installation body main body 29C in the longitudinal direction, over the entire width direction of the installation body main body 29C.

[0067] In the detached state (see FIGS. 5(d) and 5(e)) in which the installation body appendage 29D is detached from the installation body main body 29C, the installation body appendage 29D can be easily installed with bare hands on the installation body main body 29C. Even in the detached state, the base 3 is installed on the base installation part 31 of the installation body appendage 29D, and the light-emitting part 5 is installed on the light-emitting part installation part 33.

[0068] In the light emitting device 1d, the installation body 29 is configured to include an installation body main body 29C and an installation body accessory 29D that is provided with a base installation section 31 and a light emitting section installation section 33 and is configured to be detachable from the installation body main body 29C. By separating the installation body main body 29C from the installation body accessory 29D on which the base 3 and the light emitting section 5 are installed, the light emitting device 1d can be easily stored when not in use, and, for example, if the installation body main body 29C is made of toweling, the installation body main body 29C can be easily washed.

[0069] Incidentally, a fastener may be provided at connection point 41 of light emitting device 1c shown in Fig. 4, so that transparent portion 29B can be attached and detached to and from fabric portion 29A. Also, in light emitting device 5d shown in Fig. 5, the fabric of installation body attachment portion 29D may be transparent or semi-transparent.

[0070] The light-emitting device 1e shown in Figure 6 is used, for example, as a flag, and is configured with a cloth fabric portion 49 that is formed in a predetermined shape, such as a rectangular shape, and a rigid portion 51 on which the cloth fabric portion 49 is installed (supports the cloth fabric portion 49) and has a predetermined rigidity.

[0071] In the light emitting device 1e, the base installation part 31 is provided in the rigid part 51, and the light emitting part installation part 33 is provided in the fabric part 49. Note that the light emitting part installation part 33 may be provided in at least one of the fabric part 49 and the rigid part 51. Furthermore, the fabric part 49 may be made of a flexible thin plate-like synthetic resin or the like.

[0072] The rigid portion 51 is formed, for example, in a rod shape, and has a rigidity that causes only slight elastic deformation (to the extent that it only bends within the range of elasticity) or more rigidity when a force of the order of that exerted by a human finger is applied. The light-emitting unit 5 may also be provided in the fabric portion 49 in the manner shown in Fig. 3(c), for example.

[0073] The base 3 installed in the rigid portion 51 is protected by the rigid portion 51 from external forces applied to the base 3. In addition, the base 3 and the light-emitting portion 5 installed in the fabric portion 49 are also protected by the fabric portion 49 from external forces applied to the light-emitting portion 5.

[0074] In the light-emitting device 1e, the installation body 29 is configured to include a fabric portion 49 and a rigid portion 51, the base installation portion 31 is provided in the rigid portion 51, and the light-emitting portion installation portion 33 is provided in at least one of the fabric portion 49 and the rigid portion 51.

[0075] As a result, the light-emitting unit 5, which is made up of a flexible LED or the like, can be protected from external forces acting on the light-emitting unit 5 by the fabric portion 49 and the rigid portion 51. Furthermore, the light emitted by the light-emitting unit 5 is scattered, refracted, or reflected by the fabric portion 49 and the rigid portion 51, allowing the light-emitting device to emit light in a manner that is even more suited to the situation.

[0076] In the light emitting devices 1, 1a to 1q, the flexible LED 5 constituting the light emitting unit 5 may be covered with a flexible tube 53. The tube 53 is, for example, a braided tube that is transparent or translucent. Even if the braided tube 53 is opaque, the light emitted by the light emitting unit 5 exits the tube 53 through gaps 56 in the thread-like members 54 constituting the braided tube 53. The surface of the thread-like members 54 may have a high light reflectivity.

[0077] 8 is used as, for example, a headband, and has an installation body 29 configured to include a rigid portion 51 having a predetermined rigidity. The rigid portion 51 is made of, for example, a synthetic resin, and is configured to include a main body portion 55 and a protrusion portion 57. A base installation portion 31 and a light-emitting unit installation portion 33 are provided on the rigid portion 51.

[0078] More specifically, the main body 55 is the part that comes into contact with a person's head when the headband 1f is placed on the head. A pair of protrusions 57 are provided, and protrude upward from the main body 55 like rabbit ears. Furthermore, in the light emitting device 1f, two light emitting units 5 extend from the base 3, and each of the two light emitting units 5 extends from one of the two protrusions 57. The base 3 is provided at the top of the main body 55 between the pair of protrusions 57.

[0079] The protruding portion 57 has a shape in which a long, thin member is bent into a "U" shape, and the bottom end of the upside-down "U" shape is joined to the main body portion 55. The light-emitting portion 5 is provided along the "U" shape. In the light-emitting device 1f, a flexible plate-like member 59 made of fabric or the like may be provided between the protruding portion 57 and the light-emitting portion 5. The light emitted by the light-emitting portion 5 may be transmitted through the plate-like member 59 and exit to the outside of the plate-like member 59. The plate-like member 59 is provided on the light-emitting portion 5 or the protruding portion 57, for example, in the manner shown in FIG. 3(c).

[0080] The light emitting device 1g shown in Fig. 9 is used, for example, as a scarf or shawl, and has an installation body 29 made of knitted fabric. In the light emitting device 1g, the base 3 is installed in the installation body 29 at the center in the longitudinal direction of the installation body 29. In addition, in the light emitting device 1g, two light emitting units 5 extend from the base 3, and the light emitting units 5 are installed in the installation body 29, extending long in the longitudinal direction of the installation body 29, in the manner shown in Fig. 3(c).

[0081] The light emitting device 1h shown in Fig. 10 is used, for example, as a necklace. The installation body 29 of the light emitting device 1h is configured with a string-like portion 61, a first connecting body 63, and a second connecting body 65. The string-like portion 61 is configured with a chain or the like that is formed long and thin and has resistance only to tensile force in the longitudinal direction. The first connecting body 63 is provided at one end of the string-like portion 61. The second connecting body 65 is provided at the other end of the string-like portion 61. The second connecting body 65 can be attached to and detached from the first connecting body 63, for example, by using a magnet.

[0082] In the light emitting device 1h, a base mounting portion 31 on which the base 3 is mounted is provided on the first connecting body 63. Note that the base 3 is not shown in FIG. 10. Also, in the light emitting device 1h, a light emitting unit mounting portion 33 on which the light emitting unit 5 is mounted is provided on the string-like portion 61, for example, in the form shown in FIG. 7. Also, in the light emitting device 1h, a flexible plate-like member 59 made of fabric or the like is provided as the mounting body 29. In this light emitting unit 5, the light emitting unit 5 is mounted on the plate-like member 59, for example, in the form shown in FIG. 3(c). Note that the light emitting device 1h may have a configuration in which the plate-like member 59 is omitted.

[0083] In the light emitting device 1h, the installation body 29 is configured to include a string-shaped portion 61, a first connecting body 63 provided at one end of the string-shaped portion 61, and a second connecting body 65 provided at the other end of the string-shaped portion 61. The second connecting body 65 is detachable from the first connecting body 63. The base installation part 31 is provided on the first connecting body 63, and the light emitting unit 5 is provided on the string-shaped portion 61.

[0084] As a result, when the light emitting device 1h is used as a necklace, the base 3 can be protected from external forces applied to the base 3, and the light emitting unit 5 can be protected from external forces applied to the light emitting unit 5. Furthermore, by changing the shape of the light emitting unit 5 together with the string-like part 61 into various shapes, when the light emitting device 1h is used in a concert hall or the like, it can be made to emit light in a manner that is even more suited to the situation.

[0085] The light emitting device 1i shown in FIG. 11(a) is used, for example, as a hat. The installation body 29 of the light emitting device 1i is configured to include a main body 67 and a visor 69. For example, in the light emitting device 1i, the base 3 is provided at the lower end of the main body 67, and two light emitting units 5 extend from the base 3. The light emitting units 5 extend upward from the base 3, for example, at the outer surface of the main body 67, and are further provided on the main body 67 so as to circle the outer periphery of the upper end of the main body 67. Note that the light emitting units 5 may also extend along the outer periphery of the visor 69, as shown by the two-dot chain line 71 in FIG. 11(a).

[0086] The light emitting device 1j shown in FIG. 11(b) is used, for example, as a hat (cap). The installation body 29 of the light emitting device 1j is configured to include a main body portion 73 and a flange portion 75. For example, in the light emitting device 1j, the base portion 3 is not shown, but is provided at the lower end of the main body portion 73. In the light emitting device 1j, the light emitting unit 5 is provided, for example, at the lower end of the outer surface of the main body portion 73 so as to go around the main body portion 73. In addition, the light emitting unit 5 extends along the edge of the flange portion 75.

[0087] The light emitting device 1k shown in Fig. 12 is used, for example, as a wig, and the installation body 29 is configured with a plurality (a large number of) hair formations (artificial hair, human hair) 77. In the light emitting device 1k, the base 3 is installed on the hair formation 77 so as to be hidden within the hair formation body 77. The base 3 is arranged, for example, at the top of the hair formation body 77.

[0088] Furthermore, in the light-emitting device 1k, the light-emitting part 5 extends along the hair arrangement 77 and is installed on the hair arrangement 77 so that at least a part of the light-emitting part 5 appears outside the hair arrangement 77 without being hidden by the hair arrangement 77.

[0089] As a result, when the light emitting device 1k is used as a wig, the base 3 can be protected from external forces applied to the base 3, and the light emitting unit 5 can be protected from external forces applied to the light emitting unit 5. Furthermore, since the light emitting unit 5 can be changed into various shapes in accordance with changes in the shape of the hair arrangement 77, when the light emitting device 1k is used in a concert hall or the like, it can be made to emit light in a manner that is even more suited to the situation.

In addition, in the light emitting device 1n, the installation body 29 may be made up of a member formed into a ring shape by a string or the like, and the decorative part 85 shown in FIG. 14. Then, the decorative part 85 may be provided on the above-mentioned ring-shaped member in the same manner as in the light emitting device 1m.

[0095] The light emitting device 1o shown in FIG. 16 is used, for example, as a glove. The installation body 29 of the light emitting device 1o is knitted and formed in the shape of a hand. The base 3 and the light emitting unit 5 are provided on the installation body 29. The base 3 is provided on the installation body 29 at the wrist on the back side of the hand on the outer surface of the installation body 29. A plurality of light emitting units 5 (for example, five) extend from the base 3. Each of the five light emitting units 5 extends to the fingertips of each of the five fingers on the back side of the hand on the outer surface of the installation body 29. The light emitting units 5 may also be provided on the installation body 29 in the manner shown in FIG. 3(c).

[0096] The light emitting device 1p shown in Fig. 17 is used, for example, as a T-shirt. The installation body 29 of the light emitting device 1p is made of fabric and formed in the shape of a T-shirt. The base 3 and the light emitting unit 5 are provided on the installation body 29. The base 3 and the light emitting unit 5 are provided on the outer surface of the installation body 29. The light emitting unit 5 may also be provided on the installation body 29 in the manner shown in Fig. 3(c).

[0097] The light emitting device 1q shown in Figure 18 is used, for example, as a fan. The installation body 29 of the light emitting device 1q is the fan itself, and is composed of a sheet-like portion 87 and a rigid portion 89. The sheet-like portion 87 is made of fabric or thin synthetic resin, and is designed to change shape between a folded state and an unfolded state. The rigid portion 89 has a predetermined rigidity. The sheet-like portion 87 is installed on the rigid portion 89. A base installation portion 31 is provided on the rigid portion 89 (at the center of the fan), and a light emitting unit installation portion 33 is provided on at least one of the sheet-like portion 87 and the rigid portion 89.

[0098] More specifically, two light emitting parts 5 extend from one base part 3, and each of the two light emitting parts 5 extends long in the longitudinal direction of the ribs and is installed on each of the two ribs.

[0099] In the light-emitting device 1q, the installation body 29 is configured to include a sheet-like portion 87 and a rigid portion 89, the base installation portion 31 is provided in the rigid portion 89, and the light-emitting unit installation portion 33 is provided in at least one of the sheet-like portion 87 and the rigid portion 89.

[0100] As a result, when the light emitting device 1q is used as a fan, the base 3 can be protected from external forces applied to the base 3, and the light emitting unit 5 can be protected from external forces applied to the light emitting unit 5. Furthermore, by changing the light emitting unit 5 in various ways in accordance with changes in the shapes of the sheet-like portion 87 and the rigid portion 89, when used in a concert venue or the like, the light emitting device can be made to emit light in a manner that is even more suited to the venue.

[0101] The light-emitting device 1r shown in Fig. 19 is used as shoelaces 95 for shoes 93 such as sneakers. That is, at least a part (all or a part) of the light-emitting unit 5 of the light-emitting device 1r is used as the shoelaces 95. The shoelaces 95 are designed to be attached to the shoes 93 by passing through eyelets 97 of the shoes 93.

[0102] As shown in Figure 20(b), the light-emitting unit 5 has a circular cross-sectional shape (cross-sectional shape taken along a plane perpendicular to the longitudinal direction). Furthermore, the entire outer surface of the light-emitting unit 5 is covered with a transparent or semi-transparent reinforcing material 99 (a reinforcing material that is flexible, strong against tension in the longitudinal direction, and abrasion-resistant; for example, a rubber-like tube). The cross-sectional outer shape of the reinforcing material 99 is also circular, just like the light-emitting unit 5. The cross-sectional shapes of the light-emitting unit 5 and the reinforcing material 99 may also be non-circular. For example, they may be rectangular, as shown in Figure 20(c).

[0103] The base 3 of the light emitting device 1r is attached to, for example, the tongue 101 of the shoe 93 (for example, a portion on the upper surface of the tongue 101 near the opening 103 of the shoe 93) by a fastener such as a hook-and-loop fastener (not shown). This allows the light emitting device 1r (the base 3, the light emitting part 5 covered with the reinforcing material 99) to be attached to and detached from the shoe 93.

[0104] Furthermore, in the light emitting device 1r, for example, a vibration detection sensor 43 is provided on the base 3, and the light emitting unit 5 is configured to emit light under the control of the control unit 7 in response to vibrations detected by the vibration detection sensor 43.

[0105] Incidentally, in the light emitting device 1h shown in Fig. 10(b), a pair of plate-like members 59 are provided (see also Fig. 21(a)), protruding from both sides (upper and lower sides) of the flexible LED 5. In contrast, as shown in Figs. 21(c) to 21(e), the plate-like members 59 may protrude radially from the flexible LED 5, or as shown in Fig. 21(b), the plate-like members 59 may protrude from only one side of the flexible LED 5. The form of the plate-like member 59 shown in Fig. 21 can also be applied to other light emitting devices, such as the light emitting device 1f shown in Fig. 8.

[0106] Furthermore, the light-emitting unit 5 may be mounted on a mounting body 29 made of fabric or the like, as shown in Fig. 20. In the embodiment shown in Fig. 20, the flexible LEDs 5 are passed through a plurality of through-holes 91 provided in the mounting body 29, and the mounting body 29 is gathered in the longitudinal direction of the flexible LEDs 5, so that the mounting body 29 has a gathered shape as shown in Fig. 20(c).

[0107] To explain further, before the flexible LED 5 is installed on the installation body 29, as shown in Fig. 20(a), the installation body 29 is formed, for example, in the shape of a thin, elongated rectangular plate. The through-hole 91 penetrates the installation body 29 in the thickness direction of the installation body 29. The multiple through-holes 91 are provided in the center of the installation body 29 in the width direction of the installation body 29 (the up-down direction in Fig. 20(a)). The multiple through-holes 91 are lined up in the longitudinal direction of the installation body 29 (the left-right direction in Fig. 20(a)) at predetermined intervals.

[0108] As shown in FIG. 20(b), the flexible LEDs 5 are passed through a plurality of through holes 91 of the installation body 29 so as to be positioned alternately on the front and back of the installation body 29. That is, the flexible LED 5 is passed through the through hole 91A shown in FIG. 20(b) from the front side of the installation body 29 (the front side of the paper in FIG. 20(b)) to the back side of the installation body 29 (the back side of the paper in FIG. 20(b)). The flexible LED 5 is passed through the through hole 91B from the back side of the installation body 29 to the front side of the installation body 29. The flexible LED 5 is passed through the through hole 91C from the front side of the installation body 29 to the back side of the installation body 29. This is repeated for all of the through holes 91.

[0109] After the flexible LED 5 has been passed through all of the through-holes 91, the flexible LED 5 is pulled as shown by arrow A1 in Fig. 20(b) to extend the flexible LED 5 into a straight line. After the flexible LED 5 has been passed through all of the through-holes 91, the installation body 29 is contracted as shown by arrow A2 in Fig. 20(b). This causes the installation body 29 to gather as shown in Fig. 20(c).

[0110] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
