Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0038] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0039] As shown in Figures 1 to 8, according to the first aspect of the present application, the present application provides an LED lamp tube 100, comprising a wire assembly 10, a sleeve made of a light-transmitting material, and at least two LED lamp beads 20. The wire assembly 10 includes a signal line 12 and a power line 11. The at least two LED lamp beads 20 are arranged in sequence on the signal line 12 and the power line 11 to form an LED strip, so that the power line 11 can transmit a driving voltage to the LED lamp beads 20, and the signal line 12 can transmit a driving signal to the LED lamp beads 20 to control the lighting effect of the LED lamp. In this embodiment, two adjacent LED lamp beads 20 are connected in series, and the sleeve is covered on the outside of the LED strip by a glue extrusion process. This not only uniformizes the light and prevents the bright spots of the LED lamp beads 20 from being seen, but also reduces glare, achieves 360° full-body lighting, a continuous and uniform lighting effect, and high light extraction efficiency; it also protects the wire assembly 10 and the LED lamp beads 20, and has the characteristics of simple structure and low production cost.

[0040] In an optional embodiment, the sleeve includes a cable 40 and a hollow tube body 30 that is wrapped around the outside of the cable 40 and formed as one piece, wherein the LED strip is arranged in a cavity 31 formed by the hollow tube body 30, and the cable 40 is used to compensate for the voltage drop loss generated after the power cord 11 supplies power to the LED lamp bead 20 to ensure the normal operation of the LED lamp bead 20, and also ensures that the light emitted by the LED lamp bead 20 can be transmitted through the hollow tube body 30 to the outside of the hollow tube body 30.

[0041] Exemplarily, the cable 40 includes a conductive core. When the rubber compound forming the hollow tube 30 is extruded from the extruder, the conductive core is introduced into the wire-passing die at the front end of the extruder. Then, the conductive core and the hollow tube 30 formed by extruding from the wire-passing die are pulled by a pulling mechanism, so that the conductive core and the hollow tube 30 wrapped around the outside of the conductive core can move in a preset direction. This not only has a good wrapping effect but also simplifies the process. Among them, the LED strip with the LED lamp beads 20 welded thereto can be wrapped in the cavity 31 inside the hollow tube 30 and pulled together with the hollow tube 30 through the pulling mechanism; or the LED strip with the LED lamp beads 20 welded thereto can be passed through the cavity 31 inside the hollow tube 30 after the hollow tube 30 is formed. This is not limited in this application.

[0042] In an alternative embodiment, the cable 40 comprises a metal conductor that is encased between the inner and outer walls of the hollow tube 30, eliminating the need for insulation. The LED strip is encased within a cavity 31 formed within the inner wall of the hollow tube 30, and the LED lamp beads 20 and the metal conductor are insulated from each other within the hollow tube 30. Specifically, the LED lamp beads 20 are electrically connected only to the signal line 12 and the power line 11 within the hollow tube 30, while the metal conductor only provides power compensation to the other connected LED lamp tube 100.

[0043] Exemplarily, after the hollow tube body 30 is formed, it is cut with the LED strip built into the cavity 31, and then connecting terminals 50 are respectively provided at both ends of the cut hollow tube body 30 to form an LED lamp tube 100; wherein, the LED strip is formed in the cavity 31 formed by the hollow tube body 30 and the connecting terminal 50, the metal wire and the power line 11 are connected to the power interface of the connecting terminal 50, and the signal line 12 is connected to the signal interface of the connecting terminal 50, so that the length of the LED lamp tube 100 can be set according to requirements, and the number of LED lamp beads 20 in the LED lamp tube 100 can also be set according to requirements.

[0044] After adopting the above technical solution, since the voltage required by each LED lamp bead 20 is fixed, the voltage required by the LED lamp tube 100 is also fixed. For example, the operating voltage of the LED lamp bead 20 is 3V, the number of LED lamp beads 20 in the LED lamp tube 100 is 8, and the 8 LED lamp beads 20 are arranged in series in the cavity 31. At this time, the operating voltage required by the LED lamp tube 100 is 24V; when multiple LED lamp tubes 100 are connected together through the connecting terminal 50, it is only necessary to input the operating voltage required by the LED lamp tube 100 (such as 24V) to one of the LED lamp tubes 100 through the power interface of the connecting terminal 50, and the LED lamp tubes 100 are compensated for power supply through the cable 40, so that the operating voltage in each LED lamp tube 100 can be kept consistent, thereby ensuring that the LED lamp bead 20 in each LED lamp tube 100 can work normally.

[0045] In an optional embodiment, the metal wires include a first power line 41 and a second power line 42. The first power line 41 and the second power line 42 are arranged along the length of the hollow tube 30 and symmetrically on both sides of the hollow tube 30 to disperse the arrangement of the metal wires on the inner wall of the hollow tube 30 and prevent the metal wires from clumping together and blocking the light emitted by the LED lamp beads 20. The plane formed by the LED strip in the width direction coincides with the plane where the first power line 41 and the second power line 42 are located. The plane where the first power line 41 and the second power line 42 are located divides the hollow tube 30 into two semicircular structures of equal area. The LED lamp beads 20 face one of the semicircular structures and can emit light toward the semicircular structure. The light is then evenly dispersed on the hollow tube 30 through the hollow tube 30 to form a 360-degree lamp tube with good lighting effect. The LED strip can be widely used in decoration, landscape lighting, advertising signs and other fields, and can also be used as a decorative atmosphere light source or for lighting purposes.

[0046] In an optional embodiment, the power cord 11 includes a positive power cord 111 and a negative power cord 112, wherein the positive power cord 111 is connected to the positive pin of the LED lamp bead 20, and the negative power cord 112 is connected to the negative pin of the LED lamp bead 20, and the outer side of the LED lamp bead 20 is formed with a sealing body through a glue dripping process, thereby forming a protective structure for protecting the LED lamp bead 20 and the power cord 11, which can improve the sealing performance of the LED lamp bead 20 and facilitate outdoor use.

[0047] In an optional embodiment, the sealing compound is at least wrapped around the outside of the connection points between the LED lamp bead 20 and the positive power line 111 and the negative power line 112, which can protect the LED lamp bead 20 and the connection points between the LED lamp bead 20 and the power line 11, so that the power line 11 is not easily affected by the LED lamp bead 20 and the connection points when bending. It has high reliability in use and can also improve the sealing performance of the LED lamp tube 100, especially when liquid enters the cavity 31, making it suitable for outdoor use.

[0048] After adopting the above technical solution, since the encapsulation body is encapsulated on the outside of the LED lamp bead 20 and the connection point between the LED lamp bead 20 and the power cord 11, the LED lamp bead 20 and the connection point can be protected, making it less likely to be damaged when bent or slightly stretched, thereby improving the reliability of the light strip. The packaging structure is relatively simple and the manufacturing cost is lower.

[0049] In an optional embodiment, the hardness of the sealing glue body is higher than the hardness of the hollow tube body 30 , so that when the hollow tube body 30 is bent, the sealing glue body is not easily bent and deformed.

[0050] In an optional embodiment, the sealing colloid is a transparent colloid or a colloid of a specific color, and the different color rendering of the lamp beads can be achieved through the sealing colloid to meet different usage requirements and be more flexible in use.

[0051] For example, the encapsulant can be a transparent colloid, a fluorescent colloid, a red colloid, or a jewel-colored colloid, and each LED bead 20 in the LED tube 100 can also be configured with an encapsulant of a different color to achieve different luminous color effects. The color of the LED bead 20 can be adjusted as needed to meet different usage requirements.

[0052] In an optional embodiment, the encapsulant can be formed by dispensing glue on the LED lamp beads 20 using a glue dispenser, which can achieve automated production, has a relatively mature production process, and is relatively low in cost. Of course, in the specific implementation process, the encapsulant can also be formed by manual glue dripping, which will not be described in detail here.

[0053] In an optional embodiment, there is a gap between the inner wall of the hollow tube 30 and the LED lamp beads 20, so that when the light strip is bent, it is not easy to pull the LED strip, thereby improving the reliability of use.

[0054] In an optional embodiment, the signal line 12 includes a signal output line 121 and a signal input line 122. The signal output line 121 is connected to the signal output pin of the LED lamp bead 20, and the signal input line 122 is connected to the signal input pin of the LED lamp bead 20, for controlling the LED lamp bead 20 to emit light.

[0055] In an optional embodiment, the positive power line 111, the negative power line 112, the signal output line 121 and the signal input line 122 are arranged in parallel and side by side to form a wiring structure, and the positive power line 111 and the negative power line 112 are respectively located on the two outer sides of the wiring structure to facilitate the corresponding connection of the positive power line 111 and the negative power line 112 with the first power line 41 and the second power line 42.

[0056] In an optional embodiment, the LED lamp 100 further includes connection terminals 50 electrically connected to the signal line 12 and the power line 11. The connection terminals 50 are connected to both ends of the sleeve via an injection molding process. The connection terminals 50 can be used to electrically connect to an external control device or auxiliary battery, enabling the control device to control the LED lamp 100 to emit light and the auxiliary battery to supply power to the LED lamp 100. The connection terminals 50 can also be used to interconnect multiple LED lamps 100, allowing multiple LED lamps 100 to be connected in parallel via the signal line 12 and the power line 11, and the first power line 41 and the second power line 42 to compensate for power loss during operation of the LED lamp 100.

[0057] Among them, since the connecting terminal 50 is connected to the two ends of the sleeve through the injection molding process, the sealing of the LED lamp tube 100 can be ensured, so that the LED lamp bead 20, the signal line 12 and the power line 11 can be sealed in the closed cavity 31 formed by the sleeve and the connecting terminal 50, so as to improve the use of the LED lamp tube 100, such as being set underwater.

[0058] In an optional embodiment, the connection terminal 50 includes a first connection terminal 51 and a second connection terminal 52 that cooperate with each other. The first connection terminal 51 is disposed at one end of the sleeve, and the second connection terminal 52 is disposed at the other end of the sleeve. The first connection terminal 51 and the second connection terminal 52 are each provided with a power interface and a signal interface. The power line 11 and the cable 40 are connected to the power interface, and the signal line 12 is connected to the signal interface. This allows an external control device or auxiliary battery to be electrically connected to the LED lamp 100 via the signal interface and the power interface, or allows multiple LED lamps 100 to be electrically connected via the signal interface and the power interface.

[0059] Specifically, the power interface includes a positive connector, a negative connector, a positive connector port and a negative connector port, and the signal interface includes a signal input connector and a signal output interface, wherein the positive connector, the negative connector and the signal input connector are arranged on the first connecting terminal 51, and the positive connector port, the negative connector port and the signal output interface are arranged on the second connecting terminal 52, the positive power line 111 and the first power line 41 are connected to the positive connector and the positive connector port, the negative power line 112 and the second power line 42 are connected to the negative connector and the negative connector port, the signal input connector is connected to the signal input line 122, and the signal output interface is connected to the signal output line 121, and the signal output pins of two adjacent LED lamp beads are electrically connected to the signal input pins, so that when the two LED lamp tubes 100 are connected, the positive connector, the negative connector and the signal input connector on the first connecting terminal 51 can cooperate with the positive connector port, the negative connector port and the signal output interface on the second connecting terminal 52, thereby transmitting signals and power from one LED lamp tube 100 to the other LED lamp tube 100. In addition, the first power line 41 and the second power line 42 can perform power compensation to ensure that the LED lamp beads 20 in each LED lamp tube 100 can work normally.

[0060] As shown in Figures 1 to 8, according to the second aspect of the present application, the present application provides an LED product, including a plurality of the above-mentioned LED lamp tubes 100, each LED lamp tube 100 is connected to each other through the connecting terminal 50 on the sleeve, and the voltage drop loss generated by the LED lamp bead 20 on the power line 11 is compensated by the cable 40 between two adjacent LED lamp tubes 100, so as to avoid the output voltage of the LED lamp tube 100 affecting the normal operation of the LED lamp tube 100 connected thereto.
