Referring to fig. 1 to 3, an L ED textile circuit is provided, which includes a conductive wire 100, a conductive tape 200 and a plurality of L ED beads 300, wherein an insulating layer 210 covers an outer surface of the conductive tape 200, and the conductive wire 100 and the conductive tape 200 are electrically insulated from each other.

The conductive strips 200 and the conductive metal wires 100 are arranged to form a metal fabric 400 through weaving, the length direction of the conductive strips 200 is consistent with the length direction of the metal fabric 400, and the conductive strips 200 are arranged in the central area of the metal fabric 400. the conductive strips 200 and the nearest conductive metal wires 100 on the two sides of the conductive strips 200 are arranged in an opposite interweaving mode, the conductive strips 200 comprise a plurality of welding areas 220 distributed at intervals along the length direction, and an interweaving area 230 between every two adjacent welding areas 220, the weaving mode in the welding areas 220 is that the conductive strips 200 are all warp threads, the conductive metal wires 100 are all weft threads, the outer surfaces of the welding areas 220 of the conductive strips 200 comprise insulating areas 221 and metal exposed areas 222, the metal exposed areas 222 are arranged at positions, close to one side, of the conductive strips 200, the N pole of the L ED 300 is welded to the metal exposed areas 222 of the conductive strips 200, and the P pole of the L ED 300.

The inventor finds that weaving is adopted when the circuit substrate of L ED (light emitting diode) is manufactured by using weaving technology, and weaving is adopted in the current textile production, which is divided into weaving, knitting and non-weaving, and the circuit net manufactured by using weaving is soft in shape, for example, the circuit net manufactured by using weaving in CN209358825U has gap space which is easy to change, and thus the heat dispersion and air conduction at the positive pole (heat sink position) of the circuit net pair L ED during operation are influenced.

Still another, adopt the electric stove net of weaving mode manufacturing, when it carries out the banded electrically conductive part that L ED lamp pearl 300 negative pole welded in the metal mesh, the positive pole welds the fluffy position of metal mesh, because the metal mesh self shape is very unstable relatively, can have the inconsistent problem of welding condition of all L ED lamp pearl 300 for the heat dissipation condition of every lamp pearl has great differentiation when installing more L ED on longer metal mesh, influences the control to whole heat dissipation condition, can avoid inevitably to have partial L ED heat dissipation condition under the preset standard.

Moreover, can be because the unstable metal mesh of self shape, when carrying out L ED lamp pearl 300 welding, need pull at the both ends of predetermineeing the welding end to the metal mesh to make this metal mesh shape structure relatively stable point, go to weld, then this operation can influence the gap diminishes in the metal mesh, thereby reduced the radiating effect of metal mesh to L ED.

The invention provides an L ED textile circuit, wherein a plurality of conductive metal wires 100 and conductive strips 200 form a metal fabric 400 through weaving, weaving is replaced by a weaving mode, firstly, the conductive metal wires 100 are bent to a small degree during weaving production, so that the conductive metal wires 100 are not easy to break, especially for the conductive metal wires 100 at two sides in the length direction of the metal fabric 400, the metal wires are prevented from breaking to weaken the heat dissipation effect, and firstly, the metal fabric 400 manufactured through weaving is stable in shape and structure, and a plurality of gaps of the metal fabric have relatively stable positions and shapes, so that the heat dissipation condition of each L ED lamp bead 300 in the obtained L ED textile circuit is approximately the same under the same process treatment, and the integral heat dissipation condition can be approximately reflected through the heat dissipation condition of a single L ED lamp bead 300.

Specifically, the metal cloth 400 may be disposed in a strip shape, the length direction of the conductive tape 200 coincides with the length direction of the metal cloth 400, and the conductive tape 200 is disposed in the central region of the metal cloth 400. Accordingly, the metal fabric 400 may be provided in a large plane shape, a quasi-circular shape, a circular arc shape, or more.

Fig. 1 and 2 show a situation where a plurality of beads are arranged on a single L ED textile circuit in a single row line, it can be understood that a plurality of beads arranged in a plurality of row lines side by side can be arranged on a single L ED textile circuit.

The conductive band 200 and the nearest conductive metal wires 100 on the two sides of the conductive band are arranged in an opposite interweaving rule, the conductive band 200 comprises a plurality of welding areas 220 distributed at intervals along the length direction, and an interweaving area 230 between every two adjacent welding areas 220, the conductive metal wires 100 in the welding areas 220 are woven into all warps or all wefts, the outer surface of the conductive band 200 on the welding areas 220 comprises an insulating area 221 and a metal exposed area 222, the metal exposed area 222 is arranged at a position, close to one side, of the conductive band 200, the N pole of the L ED lamp bead 300 is welded to the metal exposed area 222 of the conductive band 200, and the P pole of the L ED lamp bead 300 is welded to the conductive metal wires 100 outside the two.

The conductive metal wire 100 in the welding area 220 is woven into a full warp or a full weft, which means that one side of the welding area 220 has no conductive metal wire 100, so that the conductive band 200 can be welded with the negative electrode of the L ED lamp bead 300 at the welding area 220, wherein the area welded with the negative electrode of the L ED lamp bead 300 in the welding area 220 has no insulation isolation, namely, the metal exposed area 222 can be obtained by adopting a post-operation mode such as scraping or a method of reserving the metal exposed area 222 when the conductive band 200 is sprayed on the insulating layer 210.

L ED lamp beads 300 generate heat at the P pole, namely the positive pole, when in work, the heat dissipation is enhanced through gaps among the conductive metal wires 100 distributed in a net shape, the overall heat dissipation condition is good, the shape structure of the woven metal fabric 400 is more stable than that of the woven metal fabric 400, the heat dissipation of all L ED lamp beads 300 on the whole metal fabric 400 is basically consistent, the control of the heat dissipation is facilitated, and the situation that part of L ED lamp beads 300 is deviated from the preset condition and burnt out after being used for a period of time is avoided.

Referring to fig. 3 and 4, the metal exposed area 222 is not directly connected to the conductive wire outside the conductive band, so as to avoid a short circuit condition caused by the contact between the metal conductive wire and the cathode of the L ED lamp bead while being welded to the metal exposed area 222, in combination with fig. 3 and 4, the metal exposed area 222 in fig. 3 is rectangular, and the metal exposed area 222 in fig. 4 is circular, or other shapes, so as to facilitate the actual operation as a consideration.

Specifically, when the conductive material of the conductive metal wire 100 is consistent with the conductive material of the conductive strip 200, considering that the L ED bead 300 generates heat at the positive electrode thereof when operating, and thus consumes a part of electric energy at the positive electrode, thereby causing the charge transfer requirement to be borne by the conductive strip 200 to be lower than the charge transfer requirement to be borne by all the conductive metal wires 100 in common, when the sum of the cross sections of all the conductive metal wires 100 is S along the width direction of the conductive strip 200, the cross section area of the conductive strip 200 (80% -99%) along the width direction of the conductive strip 200 is S, which is selected to be between 0.8 and 0.99 of S, which is a preferred value range, and can also be selected to be more size-limited to facilitate actual heat dissipation.

Furthermore, the diameter and the number of the copper wires (i.e. the conductive metal wires 100) used in the L ED textile circuit are calculated by the circuit flow, and the thickness and the width of the charged belt can be correspondingly limited.

Furthermore, both sides of the metal fabric 400 along the length direction are provided with the lockstitch lines 410, the lockstitch lines 410 are formed by weaving or knitting non-melting textile lines and the conductive metal wires 100, preferably, the lockstitch lines 410 on both sides are produced by knitting, so that the attractive appearance is achieved, the lockstitch lines 410 are selected to have non-melting textile lines, and the original mode that copper wires (the conductive metal wires 100) are directly woven into the lockstitch lines 410 is replaced, so that the breakage of the conductive metal wires 100 is reduced, and the heat dissipation of the L ED lamp beads 300 by L ED textile circuits is supported.

The present embodiment provides a specific type of the conductive wire 100 and the conductive tape 200. The conductive metal wire 100 is a tinned copper wire, the conductive band 200 is a copper strip, and the outer surface of the copper strip is covered with an insulating layer 210. Copper is a metal with excellent conductivity and a suitable price. The tin plating of the copper wire is adopted, so that the oxidation of copper is prevented, and the conductivity, the weldability and the ductility are enhanced.

The insulating layer 210 is made of an insulating material with good heat resistance, such as polyimide, the heat-resistant insulating material is selected, weaving production of an L ED textile circuit and long-term use of the L ED lamp bead 300 in a L ED textile circuit are facilitated, at present, one factor limiting the textile production speed is that when the production speed is high, large heat is generated in the textile production due to friction, and the heat can affect the stability of product materials and the formation of products.

Polyimide is a good insulating material for circuits, can resist high temperature of more than 300 ℃ and low temperature of-269 ℃, the heat generated by the PN junction temperature of the light emitting diode in the working process can cause the temperature of the whole L ED circuit to rise, and the polyimide PI is not melted like most insulating materials when being heated.

Further, the metal fabric 400 may be woven by a narrow fabric weaving machine. A narrow fabric loom is selected, so that the joints of the metal fabric 400 and the joints of copper wires can be reduced, the overlock function is realized, and the overlock line 410 is convenient to operate. In the narrow fabric weaving machine, the weft needles are suspended for leading, and compared with the weft needles arranged on a common track, the narrow fabric weaving machine changes the friction mode and reduces the heat generation.

The narrow fabric weaving machine is provided with the following operation flow: the conductive metal wire 100 is guided from the left to the right of the shed by the weft needle, the right is provided with a crochet hook which is inserted into the middle of the double-weft copper wire, meanwhile, the hooking lockstitch 410 moves forwards in a chaining organization movement mode, and then the weft needle exits the shed, thereby completing one-time weaving. Since this type of weaving introduces two picks at a time in the shed, the weave pattern is 2/2 warp flats. The warp yarns are called warp assembly points on the upper surface, the weft yarns are called weft tissue points on the upper surface, and two continuous warp assembly points and two continuous weft tissue points are arranged in the warp yarn direction; or two weft group points are continuous and two warp tissue points are continuous, and the above mode can complete an interweaving cycle.

The embodiment also provides a weaving method of the metal fabric 400, which is used for weaving the metal fabric 400 in an L ED weaving circuit and comprises the L ED weaving circuit, wherein the warp-wise conductive metal wires 100 can be woven by a forward threading method or a fly threading method, when the forward threading method is adopted, 9-13 reed numbers are selected, one conductive metal wire 100 is inserted into each reed, the conductive belt 200 is independently threaded on a heald frame, the conductive belt 200 needs a heald frame specially made of engineering plastics, 4-6 reed pieces are cut at the position of the area corresponding to the conductive belt 200, the area through which the conductive belt 200 passes is coated by rubber emulsion, the interweaving rules of the conductive belt 200 and the nearest conductive metal wires 100 on the two sides of the conductive belt 200 are opposite, and the interweaving of the conductive belt 200 and the metal net woven by the conductive metal wires 100 is stopped for at least two cycles after the interweaving is carried out for at least two.

The center distance between copper wires is 0.85-1 mm, but the polyimide-coated copper sheet belt is about 5mm wide, and 5-6 reed teeth are cut off without reed removal.

In contrast to the fly-through method, the fly-through method is directed to the case where the fabric has a higher warp density and a smaller number of weave repeat warps. In this embodiment, a straight-through method is selected to obtain a relatively good gap space, but a fly-through method may also be used in the weaving production of the metal fabric 400.

The embodiment also provides a weaving machine with a cutter, which is used for producing and manufacturing the L ED textile circuit, wherein the cutter is used for cutting the insulating layer 210 of the conductive strip 200 in the metal fabric 400 at intervals to form a plurality of welding areas 220 distributed on the conductive strip 200 at intervals, for example, a narrow fabric weaving machine is used for forming the welding areas 220 of the conductive strip 200 in the metal fabric 400, so that a plurality of L ED lamp beads 300 are arranged in parallel on the conductive metal wire 100 and the conductive strip 200, and the cutter can be selected as a scraper to perform transverse scraping and can also be selected as a drill bit or the like to perform vertical drilling.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
