[0002] Luminous decorative fabrics are widely used in various fields due to their luminous effects. The principle of luminous decorative fabrics is to insert optical fibers into the fabric to form a luminous effect. In related technologies, most optical fibers in luminous decorative fabrics cannot be inserted after the fabric is woven, and the fusion degree of light and fabric is not high at this time. Even if some optical fibers are woven together with the fabric, they can only transmit light by relying on smooth optical fibers, which can achieve luminescence, but cannot display patterns. Summary of the invention

[0005] The beneficial effects of the present invention are: The optical fiber is woven together with the base fabric to form a luminous luminous fabric. At this time, the luminous fabric is a whole, which is convenient for fixing it in the required position. The optical fiber is a tubular structure, in which the smooth part is the conventional tubular optical fiber body, in which light can be transmitted. In order to display a clear pattern, compared with the structure of only setting a smooth part in the prior art, a stacking part is added.

[0007] Furthermore, the stacked portion is formed by winding or knotting the optical fiber, and the optical fiber length per unit distance of the stacked portion is greater than the optical fiber length per unit distance of the smooth portion. The stacked portion can produce more bright optical fibers, thereby achieving a brightness of the stacked portion greater than that of the smooth portion.

[0008] Furthermore, the base fabric includes weft threads and warp threads woven together, one of the weft threads and the warp threads is parallel to the weaving portion, and the weft threads and the warp threads are woven with the optical fiber to form a whole. Furthermore, the optical fiber also includes a connecting section connected to the braided section, the connecting section is not braided with the base fabric, and the connecting sections of all the optical fibers of one light-emitting unit are located on the same side and are fixed together in a connector.

DETAILED DESCRIPTION The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0017] See attached Figure 1 As shown, a luminous decorative fabric of the present invention comprises a base fabric and a luminous unit, wherein the luminous unit comprises at least one optical fiber 2, and the optical fiber 2 comprises a woven section 21 woven in the base fabric. The woven portion comprises a stacked portion 211 and a smooth portion 212, and the brightness of the stacked portion 211 is greater than the brightness of the smooth portion 212.

[0018] In this embodiment, the optical fiber 2 is woven together with the base fabric to form a luminous luminous fabric 1. At this time, the luminous fabric 1 is a whole, which is convenient for fixing it at the required position. The optical fiber 2 is a tubular structure, in which the smooth part is the conventional tubular optical fiber 2 body, in which light can be transmitted. In order to display a clear pattern, compared with the structure of only setting a smooth part in the prior art, a stacking part 211 is added. The brightness of the stacking part 211 is greater than the brightness of the smooth part. By designing the position of the stacking part 211, one light-emitting unit can display a pattern.

[0019] In one embodiment, the stacking portion 211 is formed by winding the optical fiber 2. At this time, the stacking portion 211 is a spiral or bent structure. At this time, since the optical fiber 2 is stacked multiple times, the length of the optical fiber 2 per unit distance of the stacking portion 211 is greater than the length of the optical fiber 2 per unit distance of the smooth portion 212. The stacking portion 211 can produce more bright optical fibers 2, thereby achieving a brightness of the stacking portion 211 greater than the brightness of the smooth portion.

[0020] In one embodiment, the stacking portion 211 is formed by knotting the optical fiber 2. Like winding, the knotting also makes the optical fiber 2 length per unit distance of the stacking portion 211 greater than the optical fiber 2 length per unit distance of the smooth portion 212. However, it should be noted that after the knotting, it is not easy for the light to continue to transmit forward, so the stacking portion 211 formed by the knotting is usually set at the end of the braided portion, and the end position does not require the light to continue to move forward.

[0021] In one embodiment, the stacked portion 211 and the smooth portion can be optical fiber 2 bodies with different diameters. Due to the different diameters of the stacked portion 211 and the smooth portion, the ability to transmit light is different, that is, different brightness will be caused in different areas. The diameter of the stacked portion 211 is greater than the diameter of the smooth portion. In this case, the brightness of the stacked portion 211 is greater than the brightness of the smooth portion, but the optical fiber 2 needs to be specially processed to meet this condition.

[0022] In this embodiment, as long as the brightness of the stacked portion 211 is greater than the brightness of the smooth portion 212, a bright spot can be formed in the stacked portion 211, and a pattern can be formed through the bright spot of the optical fiber 2 in a light-emitting unit.

[0023] In one embodiment, there is one light-emitting unit, and one light-emitting unit can usually only display one light-emitting pattern. In this embodiment, there are multiple light-emitting units, the number of optical fibers 2 of the multiple light-emitting units is the same and all the braided segments 21 extend along the first direction, and the corresponding optical fibers 2 of different light-emitting units are alternated in the second direction.

[0024] The optical fibers 2 corresponding to different light-emitting units are alternately arranged in the second direction, which means that the same optical fibers 2 of different light-emitting units are arranged in sequence, and then the next optical fibers 2 of different light-emitting units are arranged. Figure 2 As shown, there are two light-emitting units, namely the first light-emitting unit 23 and the second light-emitting unit 24, each of which includes four optical fibers 2, namely the first optical fiber, the second optical fiber, the third optical fiber and the fourth optical fiber. When weaving, the braided parts of the eight optical fibers 2 extend along the first direction, and the first optical fiber 23a of the first light-emitting unit, the first optical fiber 24a of the second light-emitting unit, the second optical fiber 23b of the first light-emitting unit, the second optical fiber 24b of the second light-emitting unit, the third optical fiber 23c of the first light-emitting unit, the third optical fiber 24c of the second light-emitting unit, the fourth optical fiber 23d of the first light-emitting unit, and the fourth optical fiber 24d of the second light-emitting unit are arranged along the second direction.

[0025] In one embodiment, twelve light-emitting units are provided, namely, the first light-emitting unit 23 to the twelfth light-emitting unit, and the twelve light-emitting units respectively display the patterns of the twelve constellations, and each light-emitting unit includes ten optical fibers 2, namely, the first optical fiber to the twelfth optical fiber. When weaving, these 120 optical fibers extend along the X direction. When weaving, the arrangement along the second direction is respectively the first optical fiber of the first light-emitting unit, the first optical fiber of the second light-emitting unit, the first optical fiber of the third light-emitting unit, the first optical fiber of the fourth light-emitting unit...the first optical fiber of the twelfth light-emitting unit. When the first optical fiber of the twelve light-emitting units is arranged, the second optical fiber of the first light-emitting unit, the second optical fiber of the second light-emitting unit, the second optical fiber of the third light-emitting unit, the second optical fiber of the fourth light-emitting unit...the second optical fiber of the twelfth light-emitting unit; the third optical fiber of the first light-emitting unit, the third optical fiber of the second light-emitting unit, the third optical fiber of the third light-emitting unit, the third optical fiber of the fourth light-emitting unit...the third optical fiber of the twelfth light-emitting unit. And so on, until the 120 optical fibers 2 are woven.

[0026] In this embodiment, a structure is adopted in which the optical fibers 2 corresponding to different light-emitting units are alternately arranged in the second direction, so that the distribution of different light-emitting units on the woven fabric is more uniform, thereby improving the overall visual effect.

[0027] In one embodiment, the distances between adjacent braided segments 21 in the second direction are the same, and the distribution of the light-emitting units is more uniform. Of course, the distances may also be different and can be arranged according to actual needs.

[0028] In this embodiment, since all the woven segments 21 are parallel to each other, the optical fiber 2 is woven as one of the warp or weft. The base fabric includes a woven weft 32 and a woven warp 31 woven together, and one of the woven weft 32 and the woven warp 31 is parallel to the woven portion. There will be one of the woven weft 32 or the woven warp 31 between adjacent optical fibers 2; of course, there may be no woven weft 32 or woven warp 31 between individual adjacent optical fibers 2, which may be set according to the pattern requirements, but in order to form the strength of the luminous fabric 1, the optical fiber 2 is generally not allowed to completely replace one of the woven weft 32 or the woven warp 31.

[0029] See attached Figure 1 and attached Figure 2 As shown, the optical fiber 2 further includes a connecting segment 22 connected to the braiding segment 21 . The connecting segment 22 is not braided with the base fabric, and is used to connect to an external light source 5 .

[0030] In one embodiment, since the braided sections are parallel to each other, the connecting sections 22 of all the optical fibers 2 of one light-emitting unit are located on the same side and are fixed together in a connector 4. At this time, it is convenient to connect all the optical fibers 2 belonging to one light-emitting unit to a light source 5 through a connector 4, so that all the optical fibers 2 in this light-emitting unit are lit at the same time and display the same color, which is convenient for control. As shown in the accompanying drawings, the optical fiber 2 of the first light-emitting unit 23 is fixed in the first connector 41, and the optical fiber 2 of the second light-emitting unit 24 is fixed in the second connector 42.

[0031] Of course, in one embodiment, the connecting sections 22 of the optical fiber 2 of a light-emitting unit are located on different sides, and the connecting sections 22 located on the same side are fixed in one or more connectors 4. At this time, multiple light sources 5 can be used to provide light for a light-emitting unit, and a light-emitting unit can achieve different outputs of multiple colors, making the pattern displayed by a light-emitting unit more diverse.

[0032] The connector 4 is a pipe for converging the optical fibers 2 . The connector 4 wraps a plurality of optical fibers 2 to form an optical fiber 2 bundle, which is convenient for connection with the light source 5 .

[0033] See attached Figure 1 As shown, after the braided section 21 is woven, the end of the braided section 21 away from the connecting section 22 is flush with the base fabric, that is, the optical fiber 2 and the base fabric can be cut after weaving to remove excess optical fiber 2 and reduce light leakage.

[0034] In one embodiment, a plurality of the light emitting units are provided, the numbers of the optical fibers 2 in different light emitting units are the same or different, and the braided segments 21 of the plurality of optical fibers 2 in one light emitting unit are cross-arranged. At this time, the braided segments of some optical fibers 2 in a light-emitting unit are used as warps, and the braided segments 21 of some optical fibers 2 are used as wefts, that is, the optical fibers 2 of the same light-emitting unit are also crisscrossed, and can also be woven to form a light-emitting fabric 1. It is only necessary to arrange the positions of the optical fibers 2 according to the pattern requirements. As long as the light-emitting fabric 1 can be woven, the specific arrangement of the optical fibers 2 can be set according to the requirements. However, generally, considering the convenience of processing, a structure in which the braided segments are parallel to each other is still adopted.

[0035] In this embodiment, when the optical fibers 2 are braided, the positions of the optical fibers 2 are arranged according to the pattern requirements of the light-emitting units, and a light-emitting pattern is formed through the stacking parts 211 with greater brightness on the optical fibers 2.

[0036] In one embodiment, the optical fiber 2 is an optical fiber filament, and the optical fiber filament is any one of transparent or translucent plastic fiber or reinforced glass fiber, as long as it can meet the requirements of light transmission.

[0037] See attached Figure 3 As shown, the luminous decorative fabric also includes a light-transmitting fabric 7, which is fixed on the luminous fabric 1 woven by the optical fiber 2 and the base fabric. When the optical fiber 2 and the weaving weft 32 and the weaving warp 31 are woven, a luminous fabric 1 is formed, but at this time, the light of the optical fiber 2 is easy to escape to the surroundings, affecting the visual effect, so a light-transmitting fabric 7 is set and fixed on the luminous fabric 1, which can protect the optical fiber 2 on the one hand and facilitate light focusing on the other hand.

[0038] The light-transmitting fabric 7 is fixed on the luminous fabric 1 by adhesive. The light-transmitting fabric 7 is a light-transmitting black gauze, and the black light-transmitting fabric 7 has a better light-shielding effect on the smooth portion 212.

[0039] In one embodiment, a light-transmitting hole corresponding to the position of the stacking portion 211 is opened on the light-transmitting fabric 7. At this time, other areas are partially blocked by the light-transmitting fabric 7, while the light of the stacking portion 211 can completely pass through the light-transmitting hole, making the pattern contrast larger and clearer.

[0040] In one embodiment, the Figure 2 As shown, a luminous decorative device is also disclosed, comprising the luminous decorative cloth, a light source 5 and a controller 6. The light source 5 is arranged corresponding to the luminous unit and connected to the corresponding luminous unit, and the light source 5 is variable light and connected to the controller 6.

[0041] Due to the excellent light transmission performance of the optical fiber 2, the light emitted by the light source 5 is coupled into all the optical fibers 2 of the same light-emitting unit and is transmitted along the extension direction of the optical fiber 2. In the smooth part of the optical fiber 2 where there is no winding or knotting, the light intensity of the area farther away from the light source 5 and the area closer to the light source 5 is basically consistent. The stacking part 211 is used to increase the light-emitting area of ​​a region, so that the brightness of the stacking part 211 is larger than that of other regions.

[0042] The controller 6 can control the color change of one light source 5, and can also control the on / off and color change of different light sources 5, so that one light-emitting unit can display different colors, and different light-emitting units can cooperate with each other to present different light-emitting patterns. The controller 6 stores a control program, which can be modified and written according to actual needs.

[0043] In one embodiment, the light source 5 and the controller 6 are fixed together in a housing, and a power supply unit for the light source 5 is also provided in the housing. A transmission interface is provided on the housing, and the transmission interface is electrically connected to the controller 6, and the control program can be modified and written through the transmission interface.

[0044] The luminous decorative device in this embodiment weaves the optical fiber 2 into the base fabric so that the optical fiber 2 and the base fabric form an integrated luminous fabric 1, which is easy to install. At the same time, each luminous unit forms a bright spot with greater brightness by stacking the optical fibers 2 of the stacking part 211, which increases the design freedom of the number of light spots and the distribution position, making the luminous decorative device more varied and colorful.

[0045] In one embodiment, a method for preparing the luminous decorative cloth is also disclosed, and the method comprises the following steps: The optical fiber 2, the braided weft yarns 32, and the braided warp yarns 31 are prepared.

[0046] The optical fiber 2 , the braided weft threads 32 , and the braided warp threads 31 are braided into a luminous cloth 1 , and a braided segment 21 formed by braiding the optical fiber 2 , the braided weft threads 32 , and the braided warp threads 31 includes a stacked portion 211 and a smooth portion 212 .

[0047] In one embodiment, the stacking portion 211 is formed by winding or knotting the braided segment 21 at a specified position during the braiding process, that is, the optical fiber 2 before braiding is a smooth structure, which is a smooth portion. During the braiding process, the stacking portion 211 is formed at the required position, and after the stacking portion 211 is formed, the braiding continues.

[0048] In one embodiment, the stacking portion 211 is formed by winding or knotting at a specified position when preparing the optical fiber 2. At this time, before weaving, the woven portion has been formed on the light, and then it is woven with the weft 32 and the warp 31. This requires that during the weaving process, attention should be paid to the position of the optical fiber 2, that is, the optical fiber 2 of the stacking portion 211 set in advance must be arranged and woven in a set order to form a set pattern.

[0049] The preparation method further comprises fixing a light-transmitting fabric 7 on the light-emitting fabric 1 after the light-emitting fabric 1 is woven, and the light-transmitting fabric 7 is bonded to the light-emitting fabric 1, and only then the light-emitting fabric 1 is formed.

[0050] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
