[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a light-emitting device for light-emitting bodywear which introduces light into an optical fiber exposed in at least a part of a bodywear item worn by a person.

[0002]

[Prior art]

 Generally, an optical fiber is used for the purpose of transmitting the light introduced from one end face to the other end face with almost no leakage to the outside in the middle part.However, a bent part or a curved part is formed in the middle part of the optical fiber. It is known that light can be extracted even at the middle part of the optical fiber by scratching the surface of the optical fiber. Various types of ornaments have been proposed in the past, which utilize the fact that light can leak from the middle portion and the end face of an optical fiber. In this type of ornament, the light source device for introducing light into the optical fiber is used in a stationary state, and is equipped with a comparatively large lamp, and the lamp is powered by a commercial power source. It is the current situation. Further, it is also considered that the light color of the light leakage portion formed for extracting light at the intermediate portion or the end face of the optical fiber is changed with the passage of time. Specifically, a disk-shaped filter is divided into a plurality of regions in the circumferential direction, different wavelength selection characteristics are given to each region, and this filter is rotated by a power source such as a motor. is there. By arranging such a filter between the lamp and the end face of the optical fiber, the color of the light introduced into the optical fiber is changed with the passage of time, and the color of the light leaked from the light leak part is changed. I am trying to change it.

As described above, although various ornaments using optical fibers have been proposed in the past, they are currently only used for interior decoration. Therefore, the inventors of the present invention can enhance the effect of stage costumes, night work clothes, etc. by applying the optical fiber technology used as this kind of ornaments to the body parts worn by people. Focusing on the possibility of improving safety by facilitating visual recognition from a distance, we devised a personal accessory in which the light leakage part of the optical fiber was exposed on the surface. For example, as shown in FIG. 35, a swimsuit-like garment 11 is formed as an accessory in which the light leak portion of the optical fiber 2 is exposed on at least a part of the surface (in the example of the figure, The light leak part of the optical fiber is exposed on the entire surface), and light is introduced from the light source device 3 to the optical fiber 2 so that the entire clothing 11 is caused to emit light and the color of light is changed. .

[0004]

[Problems to be solved by the device]

 By the way, if the conventional light source device 3 is applied to an accessory using the optical fiber 2, the following problems occur. That is, as shown in FIGS. 36 and 37, the light source device 3 includes a relatively large lamp 31, a motor 44 as a power source for rotating the filter 32, a cooling fan 45, and the like. Therefore, it is large, heavy, and has a large amount of heat generation. There is no choice but to use such a light source device 3 as it is, and the light source device 3 is connected to the optical fiber 2 drawn out from the stage costume or other accessory through an optical fiber cable in which the optical fiber 2 is bundled. Therefore, there is a problem that the movement of a person is restricted by the presence of the optical fiber cable. In addition, if the length of the optical fiber cable is increased in order to reduce restrictions on movement, the amount of light attenuation will increase, and there will be the problem that a sufficient amount of light cannot be obtained at the light leak part.

The present invention is intended to solve the above-mentioned problems, and it is not necessary to run an optical fiber cable, and the light source device for a light emitting accessory can be attached to the accessory. Is to provide.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the invention of claim 1 introduces light into an optical fiber exposed on at least a part of the surface of an accessory such as clothes or accessories worn by a person. A power source that is a light source device that allows light to leak from the light leakage part formed at the exposed part of the light source, that is, a light output part that emits light to be introduced into the optical fiber, and a battery that supplies power to the light output part. The optical output part and the power supply part are portable and attached to the personal accessories.

A second aspect of the present invention is a preferred embodiment of the first aspect, wherein the personal accessory is clothes. According to the third aspect of the invention, the light output section includes the light color changing means capable of changing the light color introduced into the optical fiber. According to the fourth aspect of the present invention, the light color changing means changes the light color when the light output section moves in accordance with the movement of the person.

In the invention of claim 5, the light color changing means displaces the filter having different wavelength selection characteristics depending on the light transmitting portion and the relative position of the filter with respect to the optical fiber when the light output portion moves. It consists of means.

[0009]

[Action]

 According to the configuration of claim 1, since the power supply unit is the battery and the light output unit and the power supply unit are portable and attached to the accessory, the person wearing the accessory can detect the light output unit and the light output unit. Since it is possible to move while wearing the power supply part, the use of a battery as a power supply eliminates the need to lay the optical fiber cable around with the light source device installed as in the conventional configuration, which restricts human movement. However, it is especially effective when used as stage costumes. In addition, as a result of being attached to the accessory, the distance to the light leak part is shortened and the light attenuation from the light output part to the light leak part is reduced, so even if the light emission output is small, it is sufficient from the light leak part. The amount of light can be extracted.

The structure of claim 2 is a desirable embodiment of claim 1. According to the structure of claim 3, since the light output section is provided with the light color changing means capable of changing the light color introduced into the optical fiber, by changing the color of the light leaked from the light leak section, It is possible to enhance the effect of stage costumes.

According to the structure of claim 4, since the light color changing means changes the light color when the light output section moves in accordance with the movement of the person, a separate power source is not required, and the light color is changed. Can also be made small. Moreover, the color of the light leaking from the light leaking part changes depending on the movement of the person, so that it can be used in stage costumes and the like to express a sense of dynamism, and a high staging effect can be obtained.

According to a fifth aspect of the present invention, which is a preferred embodiment of the fourth aspect, the filter has different wavelength selection characteristics depending on the light transmitting portion, and the filter for the optical fiber when the light output unit moves. Since the light color changing means is composed of the means for displacing the relative position of the optical fiber, the relative position of the filter with respect to the optical fiber can be displaced according to the movement of the person, and different light colors can be obtained depending on the position of the filter. You can take it out.

【Example】

 (Example 1) In this example, a swimsuit-like garment 11 is illustrated as an accessory as shown in FIG. Such clothes 11 can be mainly used as stage costumes for concerts and fashion shows. The garment 11 is made by using the cloth formed by the optical fiber 2, or by using the normal cloth as the base cloth and embroidering by the optical fiber 2. The fabric formed by the optical fiber 2 may be a woven fabric, a knitted fabric, a knitted fabric or the like of the optical fiber 2, and a fabric obtained by combining these methods may be used. By bending or bending the middle part of the optical fiber 2, scratching the surface of the middle part, or exposing the end face to the surface of the cloth, the light guided to the optical fiber 2 leaks to the outside. A light leakage portion is formed to allow the light to leak. Such a light leak portion is exposed on at least a part of the surface of the clothing 11, and when light is introduced into the optical fiber 2, the light leaks from the light leak portion, so that at least a part of the surface of the clothing 11 is exposed. It will emit light. Here, if the light leakage part is formed over the entire clothing 11, the silhouette of the clothes 11 is raised, and if the light leakage part is formed on a part of the clothing 11, the pattern formed by the light leakage part is raised. (In FIG. 2, the light leakage portion is formed over the entire surface of the clothing 11).

As shown in FIG. 1, the light source device 3 that introduces light into the optical fiber 2 is provided with a cylindrical case 30, and a large number of optical fibers 2 are bound together, and the end portion of the case 30 is a case. It is inserted into the connecting portion 30a which is one end. In the case 30, a lamp 31, which is an incandescent light bulb that constitutes the light output unit 3a, a filter 32a, a reflecting mirror 33, and a lens 34 are housed, and a battery 35, which is a power supply unit 3b, is housed. The filter 32a is formed in a spherical shape, and is arranged so as to be relatively freely movable between the end surface of the bundle of the optical fibers 2 and the lens 34. Here, since the filter 32a is movable, the lens 34 also functions as a protective plate for preventing the filter 32a from colliding with the lamp 31. The filter 32a is divided into a plurality of areas and is formed to have different wavelength selection characteristics for each area. Therefore, if the person wearing the clothes 11 moves and the case 30 moves so as to swing or vibrate, the filter 32a rolls in the case 30 and passes through the filter 32a. Then, the wavelength of the light introduced into each optical fiber 2 changes. As a result, the color of the light leaking from the light leaking part changes, and the light of the light leaking part is not changed by simply moving the person wearing the clothes 11 without using a power source such as a motor. The color can be changed. A switch 36 for connecting and disconnecting power to the lamp 31 is connected to the case 30 via a switch wire 37. Also, a clip 38 for facilitating carrying is integrally formed on the outer surface of the case 30 by sandwiching a part of the garment 11 and the like between the outer surface of the case 30 and the outer surface of the case 30.

By using the light source device 3 having the above-described configuration, it is not necessary to use a stationary light source device as in the related art, and the light source device 3 can be attached to the garment 11. Therefore, it is not necessary to route the optical fiber cable, the movement of the person is not restricted, and the distance between the light leak unit and the light source device 3 is shortened as compared with the case where the optical fiber cable is used, and the attenuation of light is reduced. Since the amount is small, the light emission output of the light source device 3 can be reduced, and the light source device 3 can be downsized also in this respect.

In the above configuration, the filter 32a is arranged between the optical fiber 2 and the lens 34, but if it is only necessary to prevent the filter 32a from colliding with the lamp 31, the lens 34 may be provided. Instead, only a transparent protective plate may be provided. This is the same in the following embodiments, and the lens 34 and the protective plate can be interchanged with each other. Further, since the connecting portion of the optical fiber 2 to the case 30 needs to be connected with sufficient strength so as not to come off even if a person moves violently, the light source device 3 can be attached to and detached from the clothes 11. If so, it is desirable to use an optical fiber connector for the connecting portion 30a. If the light source device 3 does not need to be attached to and detached from the clothing 11, the optical fiber 2 is bonded to the connecting portion 30a of the case 30. Is desirable.

It is desirable to use a high-luminance lamp as the lamp 31, but since the high-luminance lamp 31 generates a large amount of heat, the high temperature portion of the case 30 is made of a material having a low thermal conductivity. , Insulation material is provided in that part. In this embodiment, the switch 36 connected via the switch wire 37 is used to turn on / off the power of the light source device 3. However, the switch 36 may be directly attached to the case 30, or the switch 36 may be directly attached. Instead of 36, the power may be turned on / off by wireless remote control.

Second Embodiment In this embodiment, as shown in FIG. 3, a large number of filter small pieces 32b having various wavelength selection characteristics are housed in the space between the end face of the optical fiber 2 and the lens 34. Have a configuration. The filter piece 32b is housed so as to be movable in the space between the end surface of the optical fiber 2 and the lens 34. In this configuration, when a person moves and the case 30 moves so as to oscillate or vibrate, the filter piece 32b moves in the case 30 and the light color introduced into each optical fiber 2 changes. As a result, the color of light emitted from the light leak portion can be changed by the movement of a person. Other configurations are similar to those of the first embodiment.

Third Embodiment In this embodiment, as shown in FIG. 4, a filter 32c having a shape like a convex lens is housed in the space between the optical fiber 2 and the lens 34. As shown in FIG. 4B, the filter 32c is divided into a plurality of regions in the circumferential direction, and each region has a different wavelength selection characteristic. The minimum distance between the end face of the optical fiber 2 and the lens 34 is set to about the maximum thickness of the filter 32c, and the filter 32c comes into point contact with the end face of the optical fiber 2 and the lens 34, respectively. That is, the filter 32c is rotatable with respect to the case 30 with the straight line connecting the contact points of the filter 32c with the optical fiber 2 and the lens 34 as the center of rotation. The outer diameter of the filter 32c is formed to be slightly smaller than the inner diameter of the case 30. Therefore, when the case 30 moves, the filter 32c moves in the case 30 and rotates around the rotation center, so that the color of light introduced into each optical fiber 2 changes and the light leaks from the light leak part. The color of the emitted light changes.

Here, as shown in FIG. 5, if the wall thickness of each portion in the circumferential direction of the filter 32c is made nonuniform, the center of gravity is deviated to a portion having a large thickness and the position of the center of gravity deviates from the center of rotation. Therefore, when the case 30 moves, a moment acts on the filter 32c to facilitate rotation. Other configurations are similar to those of the first embodiment. (Example 4) In Example 3, the filter 32c was formed in a convex lens shape, and the filter 32c was brought into direct contact with the end face of the optical fiber 2 and the lens 34. However, in the present Example, As shown in FIGS. 6 and 7, the filter 32c has a convex lens shape as a whole, but bearing recesses 32 ₁ and 32 ₂ are formed on the front and back sides of the central portion having the maximum thickness in the filter 32c. In addition, one central optical fiber 2 ₁ of the bundle of optical fibers 2 is projected from the end surface of the other optical fiber 2, and the conical shaft projection 34 is formed on the surface of the lens 34 facing the filter 32c. ₁ is protruding. The filter 32c is rotatably supported by inserting the optical fiber 2 ₁ and the shaft protrusion 34 ₁ into the bearing recesses 32 ₁ and 32 ₂ . In short, the third embodiment is different from the third embodiment in that the rotation center of the filter 32c is fixedly set, but other configurations are the same as the third embodiment.

(Fifth Embodiment) In the present embodiment, as shown in FIGS. 8 and 9, the axial projection 32 ₃ is projected on the filter 32c instead of the axial projection 34 ₁ is projected on the lens 34. A bearing recess 32 ₁ is formed on the surface of the filter 32c opposite to the shaft projection 32 ₃ . In this configuration, the optical fiber 2 ₁ is inserted into the bearing recess 32 ₁ and the axial projection 32 ₃ contacts the lens 34, whereby the center of rotation of the filter 32c is positioned. A bearing recess into which the shaft protrusion 32 ₃ is fitted may be formed in the lens 34. However, if the bearing recess is not provided, a lens 34 having a normal shape can be used, and the lens can be provided at a low cost. You can do it. Other configurations are the same as those in the third embodiment.

Example 6 In this example, as shown in FIG. 10, a protective plate 39, which is a transparent flat plate, is used instead of the lens 34, and the end face of the optical fiber 2 and the protective plate 39 are separated from each other. A large number of beads-shaped filters 32d are housed between them. The filter 32d has different wavelength selection characteristics. As the shape of the filter 32d, various shapes such as spherical, hemispherical, tetrahedral, and hexahedral can be used. That is, the filter piece 32b functions similarly to the second embodiment, and when the case 30 moves, the filter 32d moves between the end face of the optical fiber 2 and the protective plate 39, whereby each optical fiber is moved. The color of light introduced into 2 changes. Other configurations are similar to those of the first embodiment.

(Embodiment 7) In this embodiment, as shown in FIG. 11, a ball bearing 40 is used as a filter 32e formed in a disc shape and provided with different wavelength selection characteristics for each circumferential region. It is rotatably supported. With this configuration, the filter 32 e easily rotates with respect to the case 30. Other configurations are similar to those of the third embodiment.

(Embodiment 8) In this embodiment, as shown in FIGS. 12 and 13, a connecting ring 30 ₁ is provided in a connecting portion 30 a of the case 30 to which the optical fiber 2 is connected, and other members are stored. It is a separate body from the main body 30 ₂ . A ball bearing 41 is interposed between the connecting ring 30 ₁ and the main body 30 ₂ and is rotatably connected to each other. As the filter 32e, as in the case of the seventh embodiment, a disk-shaped filter having different wavelength selection characteristics in each region in the circumferential direction is used. Therefore, when the case 30 moves, the main body 30 ₂ rotates with respect to the coupling ring 30 ₁ , and the filter 32e housed in the main body 30 ₂ rotates with respect to the optical fiber 2. The color of the emitted light changes, and the color of the light leaked from the light leaking part changes. With this configuration, the color of the light leaked from the light leak portion changes when the case 30 moves, but the light color can also be changed by manually rotating the main body portion 30 ₂ with respect to the connecting ring 30 ₁ . Is. Other configurations are similar to those of the third embodiment.

Example 9 In this example, as shown in FIG. 14, an interference filter 32f is used instead of the colored filter. As shown in FIG. 15, the interference filter 32f is formed in a disc shape, and a support shaft 32 ₄ is projectingly provided on both side surfaces in the diameter direction. The support shaft 32 ₄ is supported by the bearing groove 30 b formed in the case 30, and the interference filter 32 f can rotate about the support shaft 32 ₄ . Here, the interference filter 32f is arranged so as not to contact the lamp 31, and a member for protecting the lamp 31 is not necessarily required, so the lens 34 and the protective plate 39 are not provided, but the lens 34 and the protective plate 39 are not necessary. You may provide the protective plate 39 suitably.

The interference filter 32f is formed by forming a thin film of magnesium oxide, titanium oxide or the like near the surface of a base material such as glass, and the thin film is formed by using a well-known thin film forming technique such as doping or vapor deposition. To be done. The interference filter 32f of this kind changes the color of the emitted light when the incident angle of the light beam changes, so that when the case 30 moves and the interference filter 32f swings with respect to the case 30, it is introduced into the optical fiber 2. The color of the light changes, and the color of the light leaked from the light leaking part due to the movement of a person can be changed. Other configurations are similar to those of the first embodiment.

(Embodiment 10) In the present embodiment, a prism 32g made of a polyhedron having a shape in which the bottom surfaces of two pyramids are bonded to each other as shown in FIG. 17 is used instead of the colored filter. Each flat surface of the prism 32g is provided with a thin film similar to that of the ninth embodiment so as to function as an interference filter. The vertices of the two pyramids forming the prism 32g are supported between the end face of the bundled optical fibers 2 and the protective plate 39, as shown in FIG. Can be rotated. Therefore, when the case 30 moves, the prism 32g rotates in the case 30, and at this time, the incident angle of the light beam from the lamp 31 to each plane of the prism 32g changes and the color of light introduced into the optical fiber 2 changes. To do. Other configurations are similar to those of the first embodiment.

It should be noted that an abacus-shaped optical element 32 h as shown in FIG. 18 may be used instead of the prism 32 b. Similar to the prism 32g, the optical element 32h also has a thin film formed near the surface of a base material such as glass and has a function as an interference filter. The optical element 32h is supported in the case 30 so as to rotate about a straight line connecting both apexes. Further, it is arranged in the case 30 so as to be movable in a direction orthogonal to a straight line connecting both vertices. Therefore, when the optical element 32h is translated and rotated by the movement of the case 30, the color of light incident on each optical fiber 2 is changed. Other configurations are similar to those of the first embodiment.

(Embodiment 11) In the present embodiment, a case of wearing kimono, in which the personal accessories are a kimono 12 and an obi 13 as shown in FIG. In the kimono 12 of this embodiment, the pattern portion is formed by embroidery with the optical fiber 2 and the light leakage portion 21 is formed in this portion. Further, the light source device 3 is housed in a pocket, a band, a knot, a band pillow or the like so that the light source device 3 is inconspicuous.

As shown in FIG. 20, the obi 13 as an accessory is woven, woven or knotted with the optical fiber 2, or the obi 13 itself is used for the optical fiber 2. It is made of braided braid. In short, the optical fiber 2 is used for at least a part of the band 13. The end face of the optical fiber 2 is exposed at the end of the band 13 and the entire band 13 and the tip of the knot serve as a light leak part. The light source device 3 is provided so as to be located on the back of a person, and in this case, two light output parts 3a are provided, and light is introduced into each half of the band 13. Further, in the embodiment shown in FIG. 20, the two light output sections 3a are provided with a common power supply section 3b, and the light output section 3a and the power supply section 3b are connected via a connection line 42. This configuration is an example, and it goes without saying that the light output unit 3a and the power supply unit 3b may be housed in one case 30.

(Embodiment 12) This embodiment illustrates the case of Western clothing, in which the personal accessories are a dress 14 and shoes 15 as shown in FIG. In this case, a dress pattern is formed by the base material, and the optical fiber 2 is entirely folded, knitted, or partially formed with a pattern such as embroidery with the optical fiber 2 to prevent leakage. The light portion 21 is formed. The light source device 3 is arranged in a skirt or the like so as not to be exposed to the outside.

The light leakage portion 21 is exposed at the toe portion or the shoelace. In this case, the switch 36 is not conspicuous to the outside by exposing the operation portion on the front surface of the heel 15a. In such shoes 15, the effect of production is enhanced by the light emission of the toes and the shoelaces. However, since the light emission color of the light source device 3 changes in accordance with the movement of a person, the color of the shoes 15 partially changes, so that the effect of production can be further enhanced.

(Example 13) As a personal accessory, a body suit-like stage costume 16 as shown in FIG. 23 may be used. In the case of the stage costume 16, the optical fiber 2 is knitted to form the whole and a knot of the optical fiber 2 is partially formed so as to increase or decrease the amount of light emitted from the light leak portion 21, or the usual dance costume 16 The light leak part 21 may be partially formed by connecting the optical fiber 2 to the. When the stage costume 16 is entirely formed of the optical fiber 2, the entire stage light 16 emits light weakly and partly emits light strongly. Further, if the optical fiber 2 is tied to the ordinary stage costume 16, only the point portion can emit light. Moreover, since the amount of light leaked changes depending on the way of tying, the intensity of the emitted light can be changed. In the stage costume as shown in FIG. 23, the light source device 3 may be attached to the waist or back so as not to be conspicuous. Further, power supply to the optical output unit 3a may be turned on / off by remote control by radio so that the blinking operation of the optical output unit can be performed by operating a switch provided on the microphone 17.

When used for the umbrella 18, as shown in FIG. 25, the light source device 3 is housed in the handle 18a, and a plurality of optical fibers 2 are bundled and housed in a light guide having a large diameter or a pipe as a structural material. The formed rod is used to form the center rod 18b. Further, a reflecting plate 43 is provided on the tip end surface of the ridge 18c so that the light traveling through the center rod 18b is reflected so as not to leak from the end surface. The bone 18d is formed by a light guide or by reinforcing the optical fiber 2 with a structural material. One end of a portion of the bone 18d that guides light is branched from the center rod 18b, and part of the light guided through the center rod 18b is introduced into the bone 18d. In such an umbrella 18, light leaks from the tip of the bone 18d and the base to emit light.

When it is desired to cause the other part of the bone 18d or the middle rod 18b to emit light, the surface of the member that guides the light in the middle rod 18b or the bone 18d should be roughened or scratched at the important points.

In this case, the light to the light leakage portion provided on the raw cloth 18e may be branched from the center rod 18b. In the umbrella 18, the reflecting plate 43 fixed to the tip end surface of the ridge 18c may be formed with a conical protrusion 43a to be inserted into the ridge 18c, as shown in FIG. In this case, the light reflected by the protrusion 43a leaks from the tip portion of the ridge 18c, and the tip portion of the ridge 18c emits light. Here, although the luminescent color is constant in this embodiment, it is of course that the luminescent color may be changed by the movement of the umbrella 18 as in the above-described embodiments. is there.

Fifteenth Embodiment In this embodiment, a case where the personal accessory is night work clothes 19 as shown in FIG. 27 is illustrated. In some conventional night work clothes 19, a material having a high reflectance is attached to a key part of the night work clothes 19 to reflect the light from a headlight of an automobile or the like to inform the presence of a person. In the present embodiment, the light leakage portion 21 using the optical fiber 2 is formed at a portion (hatched portion) where a material having a high reflectance is conventionally used. That is, the light leakage portion 21 is formed by weaving or tying the optical fiber 2 into the base material. By forming the light leakage portion 21 to emit light in this manner, it is possible to view the light from a distance farther than in the past. In other words, it is possible to confirm the existence of a person from a distance, which increases safety. In this case, it is not necessary to change the emission color of the light source device 3. The light source device 3 may be stored in a pocket or hung on a belt.

By the way, an example of the configuration of the light leakage portion 21 formed by the optical fiber 2 in the above-described various embodiments will be described. In FIG. 28, the light leakage portion 21 having a leaf motif is formed on the base cloth 22. That is, a stitch 23 along the outer shape of a leaf is put on the surface of the base cloth 22 so that the base cloth 22 is embroidered with the optical fiber 2, and a plurality of optical fibers 2 are connected on the surface of the base cloth 22 by macrame knotting. In addition, the bent portion or the curved portion formed in the knot 24 is used as the light leakage portion 21.

At the stitch 23 portion, as shown in FIG. 29, the optical fiber 2 is folded into a pile with respect to the base cloth 22. Here, a plurality of stitches 23 are continuously formed by one optical fiber 2 as shown in FIG. 29, or one stitch 23 is formed by one optical fiber 2 as shown in FIG. You can As the shape of the stitch 23, in addition to the simple shapes shown in FIGS. 29 and 30, various shapes as shown in FIG. 31 can be used, and if these various shapes of stitches are used in combination, The staging effect can be further enhanced.

The Macrame knot 24 is formed by associating a plurality of optical fibers 2 with each other as shown in FIG. That is, the knot 24 that can be used as a macrame knot is a flat knot as shown in FIG. 33 (a), a cloisonne knot as shown in FIG. 33 (b), a left and right knot as shown in FIG. 33 (c), and a figure shown in FIG. There is such an obliquely wound knot as described above, and by adopting such a knot 24, the optical fiber 2 can be bent or curved so as not to be bent or broken.

A large amount of light leaks from these light leaking portions 21 if the curvature of bending or bending is large, so that the light can be guided to all the light leaking portions 21 on the optical fiber 2. It is desirable that the light leakage portion 21 has a small curvature at a portion of the light emitting device 2 that is close to the light source device 3 and the curvature of the light leakage portion 21 increases as the distance from the light source device 3 increases. Further, by adjusting the curvature of the light leakage portion 21 provided in the optical fiber 2, it is possible to change the light emission amount for each place.

As described above, the stitches 23 and the knots 24 are used in combination, and a plurality of stitches 23 may be formed by one optical fiber 2 or only one stitch 23 may be formed. It is possible to change the amount of light emission and the color of light emitted from each light leaking part 21 by changing, and it is possible to enhance the staging effect by changing the location of each light leaking part 21. By forming each kind of accessory using the fabric formed in this way, it is possible to enhance the effect of production as described above and to make part of the clothes 11 emit light for safety. is there.

In addition to the above-described usage example, various characters, symbols, patterns such as characters may be formed on clothes by embroidery with the optical fiber 2 so that patterns and patterns stand out as the light leakage portions 21. it can. In addition, outdoor clothing such as belts and ski wear, raincoats, hats and crowns for night safety, training wear, training shoes, embroidered paintings, signs, gloves, pocket chiefs, ties, scarves and mannequins. Displays, toys such as plush toys, corsages, bouquets, fans, fans, accessories, car accessories (car batteries can be used in this case), bicycle and motorcycle accessories, indoor decorations such as curtains and goodwill It can be used for various purposes.

Further, as shown in FIG. 34, if a bundle of 5 to 30 optical fibers 2 having a length of about 30 cm is coupled to the light source device 3 by using the above-described light source device 3, Since the emission color of the end face of the optical fiber 2 can be changed by holding and shaking the device 3 by hand, it is effective to use it as a production light in place of the conventional penlight. Further, in such a light, the light leakage portion 21 which is the tip end portion of the optical fiber 2 moves in a complicated manner, so that a unique effect can be produced. In particular, if the tip end of the optical fiber 2 is arranged so as to spread by utilizing the winding tendency of the optical fiber 2, each light leak part 21 can move freely as compared with the case where the tip end of the optical fiber 2 is bundled together. As a result, the optical fiber 2 moves more complicatedly.

It should be noted that, in each of the embodiments having the rotating portion, the eccentric means for displacing the center of gravity of the member rotating with respect to the optical fiber 2 from the extension line of the rotation center is provided. desirable. If such an eccentric means is provided, when an external force acts on the case 30, a moment acts on the rotating member and the rotating member easily rotates. The battery 35 may be a primary battery such as a manganese dry battery, an alkaline dry battery or a lithium battery, as well as a secondary battery, and may have any shape such as a button shape or a paper shape. it can. In the above embodiment, only one light source device 3 is used, but it goes without saying that a plurality of light source devices 3 may be provided if necessary.

[Effect of device]

 According to the present invention, the power supply unit is a battery, and the light output unit and the power supply unit are portable and attached to the accessory, so that a person wearing the accessory wears the light output unit and the power supply unit. Since the battery is used as a power source, it is not necessary to leave the light source device stationary and to route the optical fiber cable as in the conventional configuration, and there is an advantage that human movement is not restricted. In addition, as a result of being attached to the accessory, the distance to the light leak part is shortened and the light attenuation from the light output part to the light leak part is small, so even if the light emission output is small, it is sufficient from the light leak part. There is an advantage that a large amount of light can be extracted.

Further, in the case where the light color changing means capable of changing the light color introduced into the optical fiber is provided in the light output section, the stage costume is changed by changing the color of the light leaked from the light leak section. It has the advantage of being able to enhance the effect of presentations. Also, with the light color changing means configured to change the light color when the light output section moves with the movement of a person, a separate power source is not required, and it is possible to form a small size while making it a variable color. There is an advantage that can be done. Moreover, the color of the light leaking from the light leaking part changes depending on the movement of the person, so that it can be used in stage costumes and the like to express a sense of dynamism, which has the effect of producing a high production effect.
