Description

Technical Field

[0001] The present invention relates to the field of electronic product accessories, and in particular to an LED light strip and a manufacturing device and method thereof. Background Art

[0002] Figure 1 This is a schematic diagram of the connection method of an existing LED light strip, in which each LED lamp bead includes a positive pole and a negative pole for the power LED lamp bead, and a signal input terminal IN and a signal output terminal OUT for driving and controlling the LED lamp bead. The positive poles of multiple LED lamp beads are connected in parallel to each other, and the negative poles of multiple LED lamp beads are connected in parallel to each other, and the multiple LED lamp beads are connected in series with each other in terms of signal input, that is, the input terminal of one LED lamp bead is connected to the output terminal of the previous LED lamp bead, and the input terminal of the first LED lamp bead is directly connected to the driving module. When this light strip is working, the driving module sends a control signal to the LED lamp beads at the rear end in turn. After each LED lamp bead receives the control signal, it can only light up after obtaining the driving current from the positive and negative poles according to the control signal. The defects of this method are also relatively obvious. For example, when one of the multiple LED lamp beads is disconnected at the signal input terminal IN, all LED lamp beads at the rear end of the LED lamp bead cannot receive the control signal, resulting in all LED lamp beads at the rear end being unable to light up. In general, the fault tolerance rate is very low.

[0003] Figure 2 is corresponding to Figure 1 Schematic diagram of the actual fixing method of LED lamp beads. When fixing and connecting such LED lamp beads, first connect the three cables together through soft plastic or silicone. The plastic or silicone is arranged between two adjacent cables, so that it is convenient to fix the distance between the three cables and to weld the LED lamp beads. Among them, the two outermost cables of the three cables are the positive cable and the negative cable, respectively, and the middle cable is the signal cable. The signal cable is connected in series to the input terminal IN and the output terminal OUT of the LED lamp bead, while the positive cable is connected to the positive pole of the LED lamp bead, and the negative cable is connected to the negative pole of the LED lamp bead. And after fixing the LED lamp bead, glue or seal the periphery of the LED lamp bead, and use transparent silicone to wrap the entire LED lamp bead and the connection position of the LED lamp bead and the cable, so as to achieve waterproofing.

[0004] This connection method also has defects. First, the light-emitting direction of the LED lamp beads is only on one side of the plane where the three cables are located. That is to say, one side of the three cables emits light, and the light intensity on the back of the other side of the three cables is lower, resulting in a difference in light intensity. Summary of the invention

[0005] The object of the present invention is to provide an LED lamp bead to solve the technical problems of low fault tolerance and large difference in light intensity between the front and back sides of the light strip in the prior art.

[0006] The LED light strip of the present invention comprises a plurality of LED lamp beads, each of which has a pair of input pins and a light-emitting portion, and the light-emitting portion is connected to the input pins.

[0007] The LED light strip also includes:

[0008] Two conductors, the two conductors are arranged in parallel, and a hollow area is arranged between the two conductors;

[0009] Each of the LED lamp beads is arranged in the hollow area, and the light-emitting portion is arranged along the extension direction of the wire; a pair of input pins of each of the LED lamp beads are respectively welded to two of the wires, and a plurality of the LED lamp beads are connected in parallel with each other;

[0010] The light emitting range of the LED lamp beads covers both sides of the hollow area.

[0011] In the present invention, the LED lamp bead is arranged between two wires, and the two wires clamp the LED lamp bead, which can ensure the fixation and stability of the LED lamp bead; in addition, the light-emitting portion of the LED lamp bead is arranged along the extension direction of the wires, and is arranged in the hollow area between the wires, so the light emitted by the LED lamp bead can be emitted to both sides of the plane where the LED light strip is located through the hollow area at the same time, which can achieve a very large emission angle and reduce the change of light and dark difference compared with the prior art.

[0012] In addition, multiple LED lamp beads are connected in parallel. The front-end driver module outputs the driving current and intermittently outputs the control signal at the same time, which can control the lighting mode of multiple LED lamp beads. When one of the LED lamp beads fails, it will not affect the operation and lighting of the rear-end LED lamp beads, and the fault tolerance rate is extremely high.

[0013] The present invention also discloses a method for manufacturing an LED light strip, which manufactures the LED light strip of the present invention. Specifically, the method comprises:

[0014] The method comprises:

[0015] Step 1: two parallel wires are provided, and a connection area is provided between the two wires, the connection area being used to fix and connect the two wires;

[0016] Step 2: cutting at intervals in the connection area to form a hollow area, wherein the conductive wire exposes conductive metal at the position of the hollow area;

[0017] Step 3: Install LED lamp beads in each hollow area, each of the LED lamp beads includes a light-emitting portion and a pair of input pins, the light-emitting portion is arranged along the extension direction of the wire; the light-emitting portion is provided with grooves along the extension direction of the LED light strip, and the grooves are provided with two grooves, which are opposite to each other, and the grooves are used to accommodate the wires, and each groove accommodates one wire, and the light-emitting range of the LED lamp beads covers both sides of the hollow area;

[0018] Step 4: Soldering: Solder a pair of pins of the LED lamp bead in each hollow area to one of the wires respectively.

[0019] In the present invention, two wires with hollow areas are first made, and the wires are cut at the same time when the hollow areas are cut, and the insulation layer of the wires is also cut off, so that the conductive metal of the wires is exposed. This method is convenient for rapid production on the production line. Then, LED lamp beads are installed in each hollow area, and then the pin position of the LED lamp beads is welded to the wires to achieve connection and fixation.

[0020] The present invention can utilize the production line for rapid production, for example, the rolling cutting device cuts the hollow area, the electronic material feeding device quickly positions to the hollow area, the LED lamp beads are installed, and the LED lamp beads are welded, all of which can realize unmanned mechanized work.

[0021] The LED light strip manufactured by the method of the present invention overcomes the technical problems of low error tolerance and large difference in light intensity and brightness in the prior art.

[0022] The invention also discloses a manufacturing device for manufacturing the LED light strip using the method. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0029] Please refer to Figure 3 and Figure 4 The LED light strip 100 of the present invention first includes an LED lamp bead 10, wherein the LED lamp bead 10 has a pair of input pins 11 and a light-emitting part 12, wherein the input pins 11 are respectively positive and negative, and the light-emitting part 12 is connected to the input pins 11, and when the current passes through the input pins 11 and enters the light-emitting part 12, the light-emitting part will light up. The light-emitting part 12 of the LED lamp bead 10 is provided with a groove 121, wherein the groove 121 has two grooves, which are opposite to each other and located on both sides of the light-emitting part 12, and the groove 121 is used to fix the light-emitting part 12.

[0030] The LED light strip 100 includes two wires 20 , which are arranged in parallel. A connection area 21 is provided between the two wires 20 . The connection area 21 is made of plastic and is used to connect the two wires 20 , so that the distance between the two wires 20 is within a controllable range, and the distance is basically the same.

[0031] The LED light strip 100 is provided with a plurality of hollow areas 22 at intervals in the connection area 21. When the LED lamp beads 10 are fixed on the wires 20 to form the LED light strip 100, the light-emitting parts 12 of the LED lamp beads 10 need to be arranged along the extension direction of the wires 20. Each LED lamp bead 10 is arranged in a hollow area 22. A pair of input pins 11 of the LED lamp bead 10 are respectively welded on two wires 20. The plurality of LED lamp beads 10 are connected in parallel on the wires 20.

[0032] When there is a conduction voltage and current on the wire 20 , it can ensure that multiple LED lamp beads 10 are lit. Even if one of the LED lamp beads 10 fails and cannot be lit, it will not affect the operation of other LED lamp beads 10.

[0033] What is special is that the light-emitting area of ​​the LED lamp bead 10 covers both sides of the hollow area 22. At this time, the front and rear sides of the LED light strip 100 can emit light from the hollow area 22, thereby ensuring that the light intensity on the front and rear sides of the LED light strip 100 is basically the same, and the problem of large light intensity difference in the prior art will not occur.

[0034] When the LED lamp bead 10 of the present invention is fixed between the wires 20, the grooves 121 accommodate the wires 20, each groove 121 accommodates one wire 20, and the grooves 121 are arranged along the extension direction of the LED light strip 100. At this time, the two wires 20 are respectively located in the two grooves 121, and the two wires 20 serve the purpose of clamping and fixing the LED lamp bead 10. When the LED lamp bead 10 is welded to the wires 20, it can ensure that the LED lamp bead 10 does not shake, prevent the LED lamp bead 10 from falling off at the welding position, and improve the use time.

[0035] Among them, the input pin 11 has a bending portion 13, and the bending portion 13 is located near the wire 20 after extension, which can facilitate welding. After the bending portion 13 and the wire 20 are welded, one end of the LED lamp bead 10 located at the bending portion 13 is connected to the wire 20, and the LED lamp bead 10 is located on one side of the light-emitting portion 12 and is clamped by two wires 20, thereby ensuring that the LED lamp bead 10 is firmly fixed.

[0036] When the bending portion 13 is welded to the wire 20 , the welding position is sealed with a sealant to achieve waterproofing.

[0037] In the process of lighting up the LED light strip 100 , when the wire outputs the driving current, the control signal is output in a time-sharing manner to drive the plurality of LED lamp beads 10 to light up.

[0038] Specifically, for example, when the wire 20 inputs a square wave signal, the input pin of the LED lamp bead 10 is at a high level and is greater than the minimum lighting current, the LED lamp bead 10 will be lit. When the square wave signal is at a higher operating frequency, the LED lamp bead 10 switches between the lighting and off states, and the high frequency makes it difficult for the observer to detect the switching of the state.

[0039] When the LED lamp bead 10 needs to be controlled to be turned off, the square wave signal gives a low level with a long duration. At this time, the LED lamp bead 10 will be in the off state, and the long duration can be noticed by the observer. At this time, the LED lamp bead 10 appears to be not lit.

[0040] In order to realize the sequential lighting of multiple LED lamp beads 10, a capacitive device can be arranged inside the LED lamp bead 10 to achieve the purpose of delaying the opening of the LED lamp bead 10.

[0041] In short, it is possible to control the LED lamp beads 10 in multiple ways by connecting multiple LED lamp beads 10 in parallel only by two wires 20 and then using square wave signals.

[0042] participate Figure 5 The present invention also discloses a method for manufacturing an LED light strip, the method comprising:

[0043] Step 1: setting two wires parallel to each other, and providing a connection area between the two wires, wherein the connection area is used to connect and fix the two wires;

[0044] Step 2: cutting at intervals in the connection area to form a hollow area, wherein the conductive wire exposes conductive metal at the position of the hollow area;

[0045] Step 3: Install LED lamp beads in each hollow area, each of the LED lamp beads includes a light-emitting portion and a pair of input pins, the light-emitting portion is arranged along the extension direction of the wire; the light-emitting portion is provided with grooves along the extension direction of the LED light strip, and the grooves are provided with two grooves, which are opposite to each other, and the grooves are used to accommodate the wires, and each groove accommodates one wire, and the light-emitting range of the LED lamp beads covers both sides of the hollow area;

[0046] Step 4: Soldering: Solder a pair of pins of the LED lamp bead in each hollow area to the wires respectively.

[0047] Step 5: The pin includes a bending portion, the bending portion faces the wire, each of the bending portions is welded to the lead, and the welding position between the bending portion and the wire is sealed to achieve waterproofing.

[0048] In the present invention, two wires with hollow areas are first made, and the two wires have a connection area. When the hollow area is cut, the wires are cut at the same time, and the insulation layer of the wires is also cut off, so that the conductive metal of the wires is exposed. This method is convenient for rapid production on the production line. Then, LED lamp beads are installed in each hollow area, and then the pin position of the LED lamp beads is welded to the wires to achieve connection and fixation.

[0049] The present invention can utilize the production line for rapid production, for example, the rolling cutting device cuts the hollow area, the electronic material feeding device quickly positions to the hollow area, the LED lamp beads are installed, and the LED lamp beads are welded, all of which can realize the operation of unmanned mechanized equipment.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
