Description

[Technical Field]

[0001] The present invention relates to a linear light emitter. [Background technology]

[0002] Conventionally, optical fibers with a light source such as an LED connected to one end have been known as light emitters. Flexible optical fibers have a high degree of freedom in shape and are used for a variety of purposes, including communications, lighting, and decoration. For example, Patent Document 1 discloses a light emitter (optical fiber). In this light emitter, light from a light source passes through the optical fiber, causing the end opposite the light source to emit light. It is also possible to configure the optical fiber so that a scratch is intentionally made in a certain location, allowing light to leak from the scratch and emit light.

[0003] On the other hand, the light emitter described in Patent Document 1 has a light source only at its end, so the light from the light source weakens as it approaches the end opposite the light source, making it difficult to emit light with uniform brightness at light-emitting points far from the light source or across the end opposite the light source. Therefore, light emitters in which multiple LEDs are directly attached to an electric wire or substrate are used for lighting or decorative purposes. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 7033364 Summary of the Invention [Problem to be solved by the invention]

[0005] However, with light-emitting devices in which multiple light sources are attached to an electric wire or substrate, there is a concern that direct contact by a user with the light sources may cause malfunctions or separation of the light source connections.

[0006] The present invention was devised in consideration of these points, and the problem that the present invention aims to solve is to provide a linear light-emitting device that can emit light at the desired brightness along its length, while suppressing malfunctions and peeling of the light source connection parts, thereby improving durability. [Means for solving the problem]

[0007] One feature of a linear light-emitting device that solves the above problem is that it comprises a long, translucent protective material and a light-emitting base cloth, the light-emitting base cloth being a long, strip-shaped base cloth that is heat-resistant and flexible and has a width that allows it to be arranged within the protective material, an electrical circuit diagram configured so that conductive threads are sewn along the longitudinal direction of the strip-shaped base cloth, thereby providing electrical conductivity to the surface of the strip-shaped base cloth on which the conductive threads are sewn, and a plurality of light-emitting elements arranged along the longitudinal direction of the strip-shaped base cloth on the electrical circuit diagram and electrically connected to the electrical circuit diagram, and the light-emitting base cloth is arranged inside the protective material along the longitudinal direction of the protective material.

[0008] One feature and advantage of the above configuration is that the linear light emitter is configured by disposing a long, light-emitting base fabric inside a long, translucent protective material. The light-emitting base fabric has an electrical circuit diagram configured to be electrically conductive to the surface of the long, strip-shaped base fabric on which the conductive thread is sewn, and a plurality of light-emitting elements arranged on the electrical circuit diagram and electrically connected to the electrical circuit diagram. By disposing a plurality of light-emitting elements along the longitudinal direction of the strip-shaped base fabric, a linear light emitter can be configured in which a plurality of light-emitting elements are disposed at any location on the light-emitting base fabric. In other words, by disposing a plurality of light sources of the linear light emitter along the longitudinal direction, it is possible to emit light at a desired brightness along the longitudinal direction of the linear light emitter. Furthermore, by covering the light-emitting base fabric including the light-emitting elements with a protective material, it is possible to prevent malfunctions caused by users directly touching the light sources and peeling of connection parts, thereby improving durability.

[0009] For the above-mentioned linear light-emitting element, the electrical circuit diagram may be configured such that at least one of the upper thread and the lower thread is sewn onto the strip-shaped base cloth with the conductive thread, and the strip-shaped base cloth is arranged inside the protective material along the longitudinal direction of the protective material in a spirally twisted state.

[0010] One feature and advantage of the above configuration is that the light-emitting base fabric is a flexible belt-shaped base fabric having an electrical circuit diagram on at least one surface thereof, and a plurality of light-emitting elements are arranged on the electrical circuit diagram. By arranging the light-emitting base fabric in a spirally twisted state inside the protective material, the light-emitting elements are arranged so as to face in multiple directions from the longitudinal central axis of the protective material, and the light-emitting range in the circumferential direction of the protective material can be made wider.

[0011] For the above-mentioned linear light-emitting element, the electrical circuit diagram may be configured such that both the upper thread and the lower thread are sewn onto the strip-shaped base cloth with the conductive thread, and the light-emitting base cloth may be configured such that the plurality of light-emitting elements are arranged on both sides of the strip-shaped base cloth and are arranged inside the protective material along the longitudinal direction of the protective material.

[0012] One feature and advantage of the above configuration is that the light-emitting base fabric has an electrical circuit diagram on both sides of the belt-shaped base fabric, and multiple light-emitting elements are arranged on the electrical circuit diagram. By arranging multiple light-emitting elements on both sides of the light-emitting base fabric, the light-emitting elements are arranged so as to face in at least two directions from the longitudinal center axis of the protective material, and the light-emitting range in the circumferential direction of the protective material can be made wider.

[0013] For the linear light-emitting element, the electrical circuit diagram may have a plurality of connection parts to which metal foil thread is sewn so that the light-emitting elements can be arranged, and the plurality of light-emitting elements and the electrical circuit diagram may be electrically connected via the plurality of connection parts.

[0014] One feature and advantage of the above configuration is that the electrical circuit diagram has a plurality of connection parts where light-emitting elements can be arranged. The plurality of connection parts are formed by sewing metal foil thread. The light-emitting elements arranged at the connection parts are electrically connected to the electrical circuit diagram via the connection parts. By using metal foil thread at the connection parts, the light-emitting elements can be arranged by soldering. In other words, the light-emitting elements can be mounted more firmly.

[0015] In the linear light-emitting device, the protective material may be a hollow tube, and the light-emitting base fabric may be disposed inside the hollow tube along the longitudinal direction of the hollow tube.

[0016] One feature and advantage of the above configuration is that a hollow tube is used as a protective material for the linear light emitter, so that the light emitting base fabric can be inserted and disposed inside the hollow tube.

[0017] In the linear light-emitting device, the protective material may be a solid member made of resin, and the light-emitting base fabric may be embedded inside the solid member along the longitudinal direction of the solid member.

[0018] One feature and advantage of the above configuration is that a solid resin member is used as a protective material for the linear light emitter. This fixes the position of the light emitting base fabric disposed inside. Therefore, even if the shape of the linear light emitter is changed by bending or twisting, the position of the light emitting element disposed on the belt-shaped base fabric can be more stable. [Effects of the Invention]

[0019] By having the above-mentioned configuration, the linear light emitter of the present invention can emit light while maintaining the desired brightness along the longitudinal direction, and can suppress malfunctions and peeling of the connection parts of the light source, thereby improving durability.

[0021] First Embodiment First, a first embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 1, a linear light emitter 10 according to this embodiment has a long, light-transmitting hollow tube 12 (protective material) and a light-emitting base cloth 14 on which a plurality of light-emitting elements 8 are arranged. With the light-emitting base cloth 14 arranged inside the hollow tube 12, the linear light emitter 10 is used for, for example, illumination or decoration.

[0022] The hollow tube 12 is flexible and translucent, and may be, for example, a thin, cylindrical resin tube. Examples of materials for the resin tube constituting the hollow tube 12 include elastomer resin and PVC (polyvinyl chloride). The diameter and length of the hollow tube 12 are appropriately set depending on the application of the linear light emitting device 10.

[0023] As shown in FIG. 2, the light-emitting base fabric 14 has a strip-shaped base fabric 3 and an electrical circuit diagram 5 configured such that a conductive thread is sewn along the longitudinal direction of the strip-shaped base fabric 3, thereby providing electrical continuity to the surface of the strip-shaped base fabric 3 on which the conductive thread is sewn. The conductive thread is a thread that has conductivity. In this embodiment, metal foil thread 4 is selected as the conductive thread. The electrical circuit diagram 5 is configured on one of the front surface 3a and the back surface 3b of the strip-shaped base fabric 3. A connection portion 7 is provided on the electrical circuit diagram 5, on which a light-emitting element 8 can be arranged.

[0024] The strip-shaped base fabric 3 is a sheet-like fabric that is heat-resistant and flexible, and functions as a substrate for the light-emitting base fabric 14. For example, glass cloth is selected as the strip-shaped base fabric 3. Examples of fabrics that can be used for the strip-shaped base fabric 3 include plain weave, twill weave, and satin weave. Materials that can be used for the strip-shaped base fabric 3 include glass fiber, as well as natural fibers such as cotton and linen, and synthetic fibers such as aramid. The width, length, shape, etc. of the strip-shaped base fabric 3 are appropriately set to a width and length that can be arranged inside the hollow tube 12, depending on the length, shape, etc. of the linear light-emitting device 10.

[0025] The metal foil thread 4 is composed of a central thread, which is a thread-like fiber material, and a metal foil wrapped around the central thread. The central thread can be made of various natural or chemical fibers, such as cotton, aramid, or polyester. The metal foil is made by rolling a metal plating or alloy into a rectangular wire, and is used to ensure the conductivity of the metal foil thread. In this embodiment, for example, copper foil is selected. The metal foil is wrapped around the central thread so that the electrical circuit diagram 5 is conductive. The metal foil thread 4 may be configured so that the metal foil is wrapped around the central thread so that the central thread is partially exposed. Alternatively, the metal foil may be wrapped around the central thread so that the entire length of the central thread is covered.

[0026] The electrical circuit diagram 5 is a circuit formed by sewing metal foil thread 4 (conductive thread) onto the belt-like base fabric 3. In this embodiment, it is embroidered on the belt-like base fabric 3 using metal foil thread 4 as the upper thread and non-conductive thread as the lower thread. As a result, the metal foil thread 4 is exposed on the surface of the belt-like base fabric 3 on the upper thread side (e.g., surface 3a), thereby forming the electrical circuit diagram 5. For example, an embroidery machine or an embroidery sewing machine is used to embroider the belt-like base fabric 3. The pattern of the electrical circuit diagram 5 is appropriately set depending on the application of the linear light-emitting device 10. The electrical circuit diagram 5 is formed on one surface of the belt-like base fabric 3 by sewing either the upper thread or the lower thread on the belt-like base fabric 3 with metal foil thread 4. In other words, it may be configured to be embroidered on the belt-like base fabric 3 using non-conductive thread as the upper thread and metal foil thread 4 (conductive thread) as the lower thread. In this case, the electrical circuit diagram 5 is formed on the surface on the lower thread side.

[0027] The electrical circuit diagram 5 according to this embodiment has a wiring portion 6 extending along the longitudinal direction of the belt-shaped base fabric 3 and a plurality of connection portions 7 arranged at predetermined intervals on the wiring portion 6. The wiring portion 6 is a region where the metal foil thread 4 is embroidered in a linear pattern using a running stitch. The length of the stitches is set appropriately. The connection portion 7 has two pad portions 7a, 7b embroidered in a substantially rectangular shape so that the metal foil thread 4 is concentrated. A light-emitting element 8 can be arranged across these pad portions 7a, 7b. In other words, the connection portion 7 functions as an electrode that electrically connects the light-emitting element 8 arranged on the electrical circuit diagram 5 to the electrical circuit diagram 5. The metal foil thread 4 is sewn at the connection portions 7 by an embroidery method that is appropriately selected, such as a satin stitch that sews the ends of the connection portions 7 together, or a tatami stitch that embroiders with stitches that are finer than a satin stitch.

[0028] Depending on the application, connection terminals (not shown) are provided on the light-emitting base fabric 14. The connection terminals electrically connect the wiring part 6 to a power source.

[0029] The light-emitting base fabric 14 has a light-emitting element 8 arranged on an electrical circuit diagram 5. Examples of the light-emitting element 8 include an LED. The light-emitting base fabric 14 on which the light-emitting element 8 is arranged has electrodes of the light-emitting element 8 soldered to the respective pad portions 7a, 7b at the connection portion 7. The electrical circuit diagram 5 and the light-emitting element 8 are electrically connected via the connection portion 7.

[0030] Since the strip-shaped base cloth 3 is made of a fibrous material, the luminescent base cloth 14 can be disposed in the hollow tube 12 in a twisted state as shown in Figure 3. Specifically, one end 3c and the other end 3d in the longitudinal direction of the strip-shaped base cloth 3 rotate in opposite directions around the longitudinal axis. The number of rotations (twists) can be set arbitrarily.

[0031] As shown in FIG. 1 , the linear light emitter 10 is disposed inside the hollow tube 12 along the longitudinal direction of the hollow tube 12 with the light emitting base fabric 14 twisted in a spiral. For example, the light emitting base fabric 14 is wound spirally around a small-diameter round rod core, inserted into the hollow tube 12 together with the round rod core, and finally, the round rod core alone is pulled out, thereby disposing the light emitting base fabric 14 inside the hollow tube 12. The light emitting base fabric 14 inside the hollow tube 12 is disposed in a twisted state by itself, rather than being wrapped around a separate member. As shown in FIG. 4 , in a side view of the hollow tube 12 from the axial direction, the light emitting elements 8 are disposed so as to face in multiple directions from the longitudinal center axis of the hollow tube 12. In other words, multiple light emitting elements 8 are disposed around the circumferential direction of the linear light emitter 10.

[0032] The linear light emitting body 10 has light emitting elements 8 arranged freely according to the application and is used for illumination or decoration. For example, it can be mounted on a linear stitching embroidery machine, and the light emission direction can be freely set on the embroidery machine.

[0033] <Effects of the embodiment> The linear light emitter 10 according to the embodiment has a configuration in which a long, light-emitting base fabric 14 is disposed inside a long, translucent hollow tube 12 (protective material). The light-emitting base fabric 14 includes an electrical circuit diagram 5 configured to be electrically conductive to the surface of the long, strip-shaped base fabric 3 on which the metal foil thread 4 (conductive thread) is sewn, and a plurality of light-emitting elements 8 disposed on and electrically connected to the electrical circuit diagram 5. By disposing a plurality of light-emitting elements 8 along the longitudinal direction of the strip-shaped base fabric 3, a linear light emitter 10 can be configured in which a plurality of light-emitting elements 8 are disposed at any position on the light-emitting base fabric 14. In other words, by disposing a plurality of light sources of the linear light emitter 10 along the longitudinal direction, the linear light emitter 10 can emit light with a desired brightness maintained along the longitudinal direction. Furthermore, by covering the light-emitting base fabric 14 including the light-emitting elements 8 with the hollow tube 12, it is possible to prevent malfunctions caused by users directly touching the light sources and peeling of connection portions, thereby improving durability.

[0034] The light-emitting base fabric 14 of the linear light-emitting device 10 has an electrical circuit diagram 5 formed on one side of a flexible strip-shaped base fabric 3, and a plurality of light-emitting elements 8 arranged on the electrical circuit diagram 5. By arranging the light-emitting base fabric 14 in a spirally twisted state inside the hollow tube 12, the light-emitting elements 8 are arranged to face in multiple directions from the longitudinal central axis of the hollow tube 12, and the light-emitting range in the circumferential direction of the hollow tube 12 can be made wider. Therefore, for example, light can be emitted in all directions in the circumferential direction of the linear light-emitting device 10.

[0035] The electrical circuit diagram 5 of the linear light-emitting device 10 has a plurality of connection parts 7 at which light-emitting elements 8 can be arranged. The plurality of connection parts 7 are formed by sewing metal foil threads 4. The light-emitting elements 8 arranged at the connection parts 7 are electrically connected to the electrical circuit diagram 5 via the connection parts 7. By using the metal foil threads 4 for the connection parts 7, the light-emitting elements 8 can be arranged by soldering. Therefore, the light-emitting elements 8 can be firmly mounted.

[0036] The light-emitting element 8 is soldered to the light-emitting base fabric 14 on the electrical circuit diagram 5. This allows the light-emitting element 8 to be firmly mounted, and damage to the light-emitting base fabric 14 due to the light-emitting element 8 peeling off can be suppressed.

[0037] The linear light emitter 10 has multiple light emitting elements 8 arranged at predetermined intervals along the entire length of the light emitting base fabric 14, so that the linear light emitter 10 can emit light with uniform brightness from one end to the other in the longitudinal direction.

[0038] The linear light emitter 10 can be curved or bent freely depending on the application because the flexible light emitting base cloth 14 is disposed inside the flexible hollow tube 12. Furthermore, the light emitting base cloth 14 is disposed in a twisted state by itself inside the hollow tube 12, rather than being wrapped around a separate member such as a core material, which makes it easier to change the shape of the linear light emitter 10.

[0039] In the linear light emitting device 10, since the belt-shaped base cloth 3 has heat resistance, damage to the light emitting base cloth 14 due to heat can be prevented, and safety can be ensured.

[0040] The linear light emitter 10 can be disposed by inserting the light emitting base fabric 14 into the hollow tube 12 using the hollow tube 12 as a protective material.

[0041] Second Embodiment Next, a second embodiment of the present invention will be described. Components substantially similar to those of the first embodiment will be assigned the same reference numerals and explanations thereof will be omitted, and differences will be mainly described. As shown in Figures 5 and 6, the linear light-emitting device 20 according to the second embodiment has a long, translucent hollow tube 12 (protective material) and a light-emitting base cloth 24 on which a plurality of light-emitting elements 8 are arranged. The light-emitting base cloth 24 is arranged in the hollow tube 12, and the linear light-emitting device is used for illumination or decoration, for example.

[0042] The light-emitting base cloth 24 has a strip-shaped base cloth 3 and an electric circuit diagram 5 formed by sewing a metal foil thread 4 along the longitudinal direction of the strip-shaped base cloth 3. The electric circuit diagram 5 is sewn on the strip-shaped base cloth 3 with both an upper thread and a lower thread using the metal foil thread 4. As a result, the electric circuit diagram 5 is formed on both sides (front surface 3a and back surface 3b) of the strip-shaped base cloth 3. The electric circuit diagram 5 is provided with connection parts 7 on which light-emitting elements 8 can be arranged.

[0043] The light-emitting base cloth 24 has a plurality of light-emitting elements 8 arranged in the electrical circuit diagram 5 on both sides 3a, 3b of the strip-shaped base cloth 3. For example, the light-emitting elements 8 may be arranged alternately at the connection parts 7 on the front surface 3a and the connection parts 7 on the back surface 3b. The linear light-emitting body 20 is arranged inside the hollow tube 12 along the longitudinal direction of the hollow tube 12 without twisting the light-emitting base cloth 24. Since a plurality of light-emitting elements 8 are arranged on both sides 3a, 3b of the strip-shaped base cloth 3, light is emitted in two directions from the longitudinal center axis of the hollow tube 12, sandwiching the strip-shaped base cloth 3 therebetween. The light-emitting base cloth 24 may also be arranged inside the hollow tube 12 in a twisted state.

[0044] <Effects of the embodiment> The linear light emitter 20 according to the second embodiment has the following effect in addition to the effects described above in the first embodiment. The light emitting base cloth 24 of the linear light emitter 20 has an electrical circuit diagram 5 formed on both sides (front surface 3a and back surface 3b) of the strip-shaped base cloth 3, and a plurality of light emitting elements 8 are arranged on the electrical circuit diagram 5. By arranging a plurality of light emitting elements 8 on both sides of the light emitting base cloth 24, the light emitting elements 8 are arranged to face in at least two directions from the longitudinal central axis of the hollow tube 12, and the light emitting range in the circumferential direction of the hollow tube 12 can be made wider.

[0045] The linear light-emitting body 20 has a plurality of light-emitting elements 8 arranged on both sides of the light-emitting base fabric 24, so that even when the linear light-emitting body 20 is arranged inside the hollow tube 12 with a small number of twists, the light-emitting range in the circumferential direction of the hollow tube 12 can be widened.

[0046] Third Embodiment Next, a third embodiment of the present invention will be described. The same reference numerals will be used to designate components substantially similar to those of the first or second embodiment, and the description will be omitted, with differences being the focus of the description. As shown in Fig. 7, the linear light-emitting device 30 according to the third embodiment has a translucent, long, solid member 32 (protective material) and a light-emitting base cloth 14 on which a plurality of light-emitting elements 8 are arranged. The light-emitting base cloth 14 is embedded in the solid member 32, and the linear light-emitting device is used for illumination or decoration, for example.

[0047] The solid member 32 is made of a flexible and light-transmitting silicone resin. The solid member 32 is formed, for example, in the shape of a long, thin round rod. The diameter and length of the solid member 32 are set appropriately depending on the application of the linear light emitting device 30.

[0048] 2, the light-emitting base fabric 14 has a strip-shaped base fabric 3 and an electric circuit diagram 5 formed by sewing metal foil threads 4 along the longitudinal direction of the strip-shaped base fabric 3. The electric circuit diagram 5 is formed on one of the front surface 3a and the back surface 3b of the strip-shaped base fabric 3. A connection part 7 on which a light-emitting element 8 can be disposed is provided on the electric circuit diagram 5.

[0049] The light-emitting base fabric 14 has a plurality of light-emitting elements 8 arranged on the electrical circuit diagram 5. The electrodes of the light-emitting elements 8 are soldered to the respective pad portions 7a, 7b at the connection portion 7. The light-emitting elements 8 are electrically connected to the electrical circuit diagram 5 via the connection portion 7. As shown in FIG. 7, the linear light-emitting element 30 is embedded inside the solid member 32 along the longitudinal direction of the solid member 32 without twisting the light-emitting base fabric 14. The light-emitting base fabric 14 is positioned near the center in a cross-sectional view of the solid member 32 as seen from the axial direction.

[0050] The width and position of the light-emitting base fabric 14 in the linear light-emitting device 30 are set as appropriate. For example, as shown in FIG. 7, the light-emitting base fabric 14 may be arranged so that, in a cross-sectional view of the solid member 32 as seen from the axial direction, the cross-section of the solid member 32 is partitioned by the light-emitting base fabric 14. As shown in FIG. 8, the width of the light-emitting base fabric 14 may be shorter than the diameter of the solid member 32 and the light-emitting base fabric 14 may be arranged near the center. As shown in FIG. 9, the light-emitting base fabric 14 may be arranged along the periphery of the solid member 32. The light-emitting base fabric 14 may also be arranged inside the solid member 32 in a twisted state.

[0051] The linear light-emitting element 30 may be configured by embedding a light-emitting base cloth 24 having a plurality of light-emitting elements 8 arranged on both sides 3a, 3b of the belt-shaped base cloth 3. Light is emitted from the longitudinal center axis of the solid member 32 in two directions across the belt-shaped base cloth 3. The light-emitting base cloth 24 may be arranged inside the solid member 32 in a twisted state.

[0052] <Effects of the embodiment> The linear light emitter 30 according to the third embodiment has the following advantages in addition to the advantages described above in the first and second embodiments: The linear light emitter 30 has flexible light emitting base fabrics 14, 24 embedded in a flexible solid member 32, and therefore can be curved or bent freely depending on the application.

[0053] The linear light emitter 30 uses a solid member 32 as a protective material, thereby fixing the position of the light emitting base fabrics 14, 24 disposed inside. Therefore, even if the shape of the linear light emitter 30 is changed by bending or twisting, the position of the light emitting element 8 disposed on the belt-shaped base fabric 3 can be more stable. Furthermore, peeling of the light emitting element 8 can be prevented.

[0054] The linear light-emitting element of the present invention is not limited to the appearance and configuration described in the above embodiment, but can be embodied in various other forms by various modifications, additions, deletions, and combinations of configurations within the scope that does not change the gist of the present invention.

[0055] For example, the hollow tube into which the luminescent base fabric is inserted may be a tube made of glass, polycarbonate, acrylic, etc. Furthermore, the shapes of the hollow tube and solid member are not limited to those having a circular cross section, but may also have other cross sections such as an ellipse or a polygon.

[0056] The linear light emitter 10 according to the first embodiment may be disposed without twisting the light emitting base fabric 14.

[0057] The conductive threads constituting the electrical circuit diagram 5 are not limited to the metal foil threads 4, and various conductive threads can be used. For example, conductive threads made of a core material such as polyester or nylon plated with a conductive material such as silver, copper, or nickel may be used.

[0058] The electric circuit diagram 5 may be configured such that at least a part of the wiring portion 6 uses conductive threads other than the metal foil threads 4.

[0059] The light-emitting base fabrics 14, 24 may be configured such that the light-emitting element 8 disposed at the connection portion 7 is mounted with an adhesive. In this case, other conductive threads may be used at the connection portion 7 instead of the metal foil thread 4. Also, the light-emitting element 8 may be mounted with an adhesive without providing the connection portion 7 on the electrical circuit diagram 5.

[0060] The linear light emitters 10, 20, and 30 are not limited to a configuration in which the light emitting elements 8 are arranged at regular intervals on the electrical circuit diagram 5, but may be configured to be arranged at any intervals. In other words, the intervals between adjacent light emitting elements 8 may be different from each other. This allows the linear light emitters 10, 20, and 30 to be configured so that their brightness varies partially depending on the application or purpose.

[0061] The belt-shaped base cloth 3 in the linear light-emitting devices 10, 20, 30 may be a single sheet-shaped cloth, or may be configured by stacking a plurality of sheet-shaped cloths.

[0062] The light-emitting base fabrics 14, 24 may be configured such that multiple electrical circuit diagrams 5 are formed on one side of a single belt-shaped base fabric 3. In other words, multiple circuits in which light-emitting elements 8 are arranged may be formed on one side or on each side. [Explanation of symbols]
