Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting equipment technology, and in particular to a series-connected light string conductive structure, and a light string having a series-connected light string conductive structure. Background Technology
[0002] In the field of lighting equipment technology, string lights, as a common decorative and lighting tool, are widely used in various scenarios such as festivals, celebrations, interior decoration, and outdoor landscaping. Traditional string lights primarily employ a parallel connection structure. While each bulb can operate independently, and the failure of one bulb usually doesn't affect the normal operation of the others, parallel circuits require a higher voltage to drive all the bulbs, making them less adaptable to low-voltage power supplies. When using low-voltage power supplies, such as 3-5V, parallel string lights often fail to function properly or require additional booster equipment. This not only increases cost and complexity but also makes them difficult to apply in scenarios with stringent power requirements. Furthermore, parallel string lights suffer from significant line losses and low power transmission efficiency over long distances, hindering their ability to be extended indefinitely and limiting their application in large-scale decorative settings.

[0041] In the field of lighting equipment technology, string lights, as a common decorative and lighting tool, are widely used in various scenarios such as festivals, celebrations, interior decoration, and outdoor landscaping. Traditional string lights primarily employ a parallel connection structure. While each bulb can operate independently, and the failure of one bulb usually doesn't affect the normal operation of the others, parallel circuits require a higher voltage to drive all the bulbs, making them less adaptable to low-voltage power supplies. When using low-voltage power supplies, such as 3-5V, parallel string lights often fail to function properly or require additional booster equipment. This not only increases cost and complexity but also makes them difficult to apply in scenarios with stringent power requirements. Furthermore, parallel string lights suffer from significant line losses and low power transmission efficiency over long distances, hindering their ability to be extended indefinitely and limiting their application in large-scale decorative settings.
[0042] Therefore, such as Figures 1 to 6As shown, this utility model proposes a series light string conductive structure, which includes a wire group 100 and a plurality of light-emitting components 200 connected to the wire group 100. The wire group 100 includes a positive electrode wire 110, a negative electrode wire 120 and a connecting wire 130. The two ends of the connecting wire 130 are respectively connected to the positive electrode wire 110 and the negative electrode wire 120. Furthermore, the connecting wire 130 is provided with multiple disconnect holes 1301, and multiple light-emitting components 200 are arranged one-to-one with the disconnect holes 1301. Specifically, the light-emitting component 200 includes a lamp holder 210 and a lamp head 220. The lamp holder 210 is provided with a first conductive element 211 and a second conductive element 212 arranged separately. For example, referring to the structure of a conventional copper-head lamp, the first conductive element is located at the bottom of the lamp holder, corresponding to the live wire interface at the bottom of the lamp head of the copper-head lamp, and the second conductive element is located on the inner circumferential wall of the lamp holder, corresponding to the neutral wire interface (not shown in the figure) connected at the threaded part of the lamp head of the copper-head lamp. For another example, the first conductive element 211 and the second conductive element 212 are arranged circumferentially at intervals in the lamp holder 210. In some applications, the lamp head is provided with an insulating post, a first conductive ring, and a second conductive ring. Two conductive rings are arranged, with the first conductive ring corresponding to the live wire interface and the second conductive ring corresponding to the component interface. That is, the first and second conductive rings are arranged opposite each other in the radial direction of the insulating post (not shown in the figure). Optionally, both the first and second conductive rings are semi-circular. When the first and second conductive rings are on the same horizontal plane, the central angle corresponding to the semi-circular first and second conductive rings is less than 180°. When the first and second conductive rings are staggered, the central angle corresponding to the semi-circular first and second conductive rings can be 1° to 359°. Thus, the lamp holder can be directly inserted into the lamp holder through the insulating post. After insertion, the first and second conductive components in the lamp holder are electrically connected to the first and second conductive rings respectively (not shown in the figure). In some applications of this embodiment, the first conductive ring 221 and the second conductive ring 222 are arranged at intervals along the axial direction of the insulating post 2201. The insulating post 2201 is threadedly connected to the lamp holder 210 to drive the first conductive ring 221 to contact and conduct with the first conductive element 211, and to drive the second conductive ring 222 and the second conductive element 212 to contact and conduct, thereby realizing a reliable electrical connection between the light-emitting component 200 and the first conductive element 211 and the second conductive element 212 of the lamp holder 210. Understandably, the axially spaced arrangement of the insulating posts 2201 ensures the electrical isolation between the first conductive ring 221 and the second conductive ring 222. During the tightening process, the threaded connection structure automatically drives the first conductive ring 221 to make close contact with the first conductive element 211 and the second conductive ring 222 to make close contact with the second conductive element 212, which not only simplifies the assembly process of the lamp holder 220 and the lamp base 210, but also ensures the mechanical stability of the connection through the self-locking characteristics of the thread, effectively resisting loosening caused by vibration or external force, and ensuring that the low voltage current is stably transmitted from the conductive element of the lamp base 210 to the light source 230 through the conductive ring, thereby improving the overall electrical connection reliability and safety of use.Furthermore, the same end of the first conductive element 211 and the second conductive element 212 is placed inside the lamp holder 210 to conduct electricity with the lamp head 220. The other ends of the first conductive element 211 and the second conductive element 212 both protrude from the lamp holder 210. In application, the first conductive element 211 and the second conductive element 212 are located on both sides of the disconnect hole 1301, and the ends of the first conductive element 211 and the second conductive element 212 that are away from the lamp head 220 can be inserted into the connecting wire 130 and conduct electricity with the connecting wire 130. It should be noted that, through a unique three-wire connection design, the positive electrode wire 110, the negative electrode wire 120, and the connecting wire 130, whose two ends are respectively connected to the positive electrode wire 110 and the negative electrode wire 120, are integrated into the wire assembly 100. Furthermore, multiple disconnect holes 1301 are provided in the connecting wire 130 to confirm the installation positions of multiple light-emitting components 200. Then, the light-emitting components 200 are connected to the lamp holder 220 through the first conductive element 211 and the second conductive element 212 arranged separately inside the lamp holder 210. The connecting wire 130 is inserted into the protruding ends of the first conductive element 211 and the second conductive element 212 corresponding to the two sides of the disconnect holes 1301 to achieve electrical connection. The structure allows each light-emitting component 200 to be stably connected to the circuit in series, which simplifies the complex soldering or plugging process of traditional light strings and ensures reliable power supply for LED bulbs at low voltages such as 3-5V. In addition, the design of the first conductive component 211 and the second conductive component 212 located on both sides of the disconnect hole 1301, together with the conduction method of directly inserting the connecting wire 130, achieves efficient current transmission and reduces line loss. This allows the light string to flexibly achieve long-distance connection or single component maintenance while ensuring low voltage compatibility. The overall structure is compact and the conductive path is clear, which significantly improves the ease of installation, power supply stability and flexibility of use of the light string.
[0043] Refer to Figure 3 , Figure 5 and Figure 6 In some embodiments of this utility model, the first conductive ring 221 is located at the bottom of the insulating post 2201, and the second conductive ring 222 is located at the top of the insulating post 2201. Furthermore, the outer diameter of the first conductive ring 221 is smaller than the outer diameter of the second conductive ring 222. Correspondingly, the first conductive element 211 and the second conductive element 212 are both strip-shaped and arranged in parallel. The first conductive element 211 abuts against the outer wall of the first conductive ring 221, and the second conductive element 212 abuts against the outer wall of the second conductive ring 222, providing conductivity. It should be noted that by utilizing the axial spacing and radial dimensional differences of the insulating posts 2201, a clear separation and stable contact between the positive and negative conductive paths are ensured, avoiding the risk of short circuits between the positive and negative electrodes. Simultaneously, the parallel strip-shaped conductive elements reduce contact resistance, improve current transmission efficiency, and have a large contact area with the outer wall of the conductive ring, further enhancing the power supply stability and consistency of the light-emitting component 200. Further reference... Figure 3 and Figure 5In some embodiments of this utility model, a light source 230 and a positive electrode wire 231 and a negative electrode wire 232 connecting the light source 230 are provided inside the lamp holder 220. A first through-line groove 22011 and a second through-line groove 22012 are opened on the insulating post 2201, realizing a precise electrical connection between the light source 230 and the conductive ring. The structure in which the positive electrode wire 231 is connected to the first conductive ring 221 through the first through-line groove 22011 and the negative electrode wire 232 is connected to the second conductive ring 222 through the second through-line groove 22012 ensures a clear and definite directional transmission path of current from the conductive ring to the light source 230, avoiding circuit failures caused by wire crossing interference or incorrect connection. At the same time, the through-line groove design provides physical fixation and direction guidance for the wires, enhances the mechanical stability of the connection between the light source 230 and the conductive ring, prevents the wires from loosening due to pulling or vibration, improves the reliability of the internal electrical connection of the lamp holder 220, and ensures stable light emission of the LED bulb and other light sources 230 and long-life use of the lamp string. In some applications, when the first conductive ring 221 is fitted around the outer periphery of the insulating post 2201, it can press the positive electrode wire 231 tightly against the outer surface of the insulating post 2201; when the second conductive ring 222 is fitted around the outer periphery of the insulating post 2201, it can press the negative electrode wire 232 tightly against the outer surface of the insulating post 2201.
[0044] Refer to Figure 3 , Figure 4 and Figure 6In some embodiments of this utility model, the ends of the first conductive member 211 and the second conductive member 212 facing away from the lamp holder 220 are each provided with a piercing portion to pierce the connecting wire 130. Specifically, the piercing portion is a first piercing portion 2111 provided on the first conductive member 211 and a second piercing portion 2121 provided on the second conductive member 212. This allows the piercing portion to directly penetrate the insulating outer sheath of the connecting wire 130 and make close contact with the internal conductor when installing the light-emitting component 200, eliminating the need to pre-strip the wire insulation layer or perform complex welding operations. This significantly simplifies the conductive connection steps and improves assembly efficiency. Furthermore, the mechanical engagement between the piercing portion and the conductor provides a stable physical connection, effectively reducing contact resistance and enhancing anti-vibration loosening performance. This ensures stable transmission of low-voltage current, significantly improving the reliability and long-term durability of the conductive connection, while avoiding the poor contact problems that may occur with traditional plug-in methods. Furthermore, in some embodiments of this utility model, two linearly spaced limiting grooves are provided in the lamp holder 210, and the first conductive element 211 and the second conductive element 212 are respectively fixedly installed in the corresponding limiting grooves. That is, the lamp holder 210 is provided with a first limiting groove 2101 and a second limiting groove 2102. The first conductive element 211 is fixedly inserted into the first limiting groove 2101, and the second conductive element 212 is fixedly inserted into the second limiting groove 2102. This achieves precise positioning and stable fixation of the first conductive element 211 and the second conductive element 212, preventing displacement or skew during use that could lead to misalignment with the disconnect hole 1301 or the connecting wire 130. In addition, the limiting groove structure ensures that the first conductive element 211 and the second conductive element 212 are strictly separated and always correspond to the ideal positions on both sides of the disconnect hole 1301, ensuring the accuracy and consistency of the conductive path, improving the stability and reliability of the electrical connection, simplifying the assembly process of the light-emitting component 200, and enhancing the mechanical stability of the overall structure. Optionally, the piercing part is arrow-shaped, and the outer surface of the limiting groove abuts against the side of the piercing part away from the connecting wire 130, so as to prevent the connecting wire 130 from shifting due to the reaction force received when it is pierced.
[0045] Refer to Figure 1 , Figure 3 , Figure 4 and Figure 6In some embodiments of this invention, a clamping cap 300 is connected to the side of the lamp holder 210 opposite to the lamp head 220. After the first conductive element 211 and the second conductive element 212 pierce the connecting wire 130, the clamping cap 300 can apply uniform pressure to the wire assembly 100, further ensuring that the conductive element and the connecting wire 130 maintain tight contact and enhancing the mechanical stability of the electrical connection. It is easily understood that the clamping action effectively compensates for potential loosening of contact due to thermal expansion and contraction of materials, vibration, or external forces, continuously maintaining a low-resistance conductive state, significantly reducing flickering, open circuit, or overheating problems caused by poor contact, extending the lifespan of the light string, and improving safety in use. Optionally, the clamping cover 300 and the lamp holder 210 are installed using a snap-fit method, enabling quick installation and removal of the clamping cover 300. The clamping cover 300 can be fixed without additional tools, simplifying the installation and maintenance process of the light string. In this regard, the snap-fit structure provides sufficient clamping force while ensuring ease of operation. Users can easily close and open the clamping cover 300 by pressing or rotating the buckle, facilitating quick re-clamping or replacement of the light-emitting component 200 in case of poor contact of conductive parts. This improves the user experience and maintainability of the light string, while maintaining the structural stability and sealing. For example, refer to... Figure 4 and Figure 6 The lamp holder 210 is provided with a snap-fit groove 2103, and the clamping cover 300 is provided with a snap-fit part 310. The snap-fit part 310 can be inserted into the snap-fit groove 2103 and engage with it. Furthermore, in some embodiments of this utility model, a lifting part 320 is provided on the clamping cover 300, providing users with a convenient way to open it. The clamping cover 300 can be opened by manually holding or prying the lifting part 320 without the need for tools, quickly releasing the clamping state and exposing the connection part between the conductive component and the connecting wire 130. The lifting part 320 design solves the problem that traditional snap-fit clamping covers 300 are difficult to open due to excessive tightness. Especially when the conductive component needs to be readjusted, inspected, or replaced, users can quickly operate and intuitively access the internal connection structure, facilitating maintenance, troubleshooting, or component replacement, significantly improving the maintainability and user-friendliness of the light string.
[0046] Refer to Figure 7In some embodiments of this utility model, a series-connected light string conductive structure includes a connector 400 and multiple wire groups 100. The multiple wire groups 100 are connected and conductive through the connector 400, realizing reliable electrical connection and conduction between multiple independent wire groups 100. This allows the light string to be seamlessly spliced into a whole of arbitrary length through the connector 400, solving the problem that traditional light strings cannot cover large areas due to the length limitation of a single wire group 100. The connector 400 maintains the continuity and stability of conductivity between each wire group 100, ensuring that the series voltage division effect is not affected by the splicing of the wire groups 100. Users can flexibly combine the length of the wire groups 100 according to actual needs, realizing the infinite splicing and extension of the light string, expanding the application range and scene adaptability of the light string, while maintaining the consistency and reliability of the overall electrical performance. For example, for the first section of the wire group 100, one end of the wire group 100 can be connected to a power plug 500, and the other end can be connected to a connector 400; for the middle section of the wire group 100, both ends of the wire group 100 can be connected to connectors 400 respectively; for the last section of the wire group 100, one end of the wire group 100 is connected to a connector 400, and the other end is a closed structure. Optionally, the positive wire 110, the connecting wire 130, and the negative wire 120 are arranged sequentially in the wire group 100. This orderly wire layout optimizes the internal spatial structure of the wire group 100, reduces cross-interference and electromagnetic coupling between wires, and reduces the risk of signal interference or short circuit. In addition, the central arrangement of the connecting wire 130 facilitates better concealment after insertion of the piercing part.
[0047] Refer to Figure 7 The light string according to an embodiment of the present invention includes a series-connected conductive structure according to an embodiment of the present invention. By adopting the series-connected conductive structure of the present invention, efficient series voltage division power supply for low-voltage LED bulbs, infinite extension of multiple wire groups 100, stable and reliable conductive connection, and convenient installation and maintenance can be achieved. It takes into account the adaptability to low-power scenarios, flexibility in long-distance arrangement, user-friendliness, and long-term reliability, and solves the technical bottlenecks of traditional light strings in low-voltage power supply, complex connection structure, and maintenance cost, significantly improving the overall performance, application range, and market competitiveness of the light string.
[0048] Other configurations and operations of the light string according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
[0049] Refer to Figure 8 The installation method according to an embodiment of the present invention is applied to a series-connected light string conductive structure according to an embodiment of the present invention, wherein the installation method includes the following steps:
[0050] S100, Position Confirmation: Take wire group 100, and open several disconnect holes 1301 in connecting wire 130 according to the preset light-emitting position;
[0051] S210, Insertion and Connection: After confirming the position, take several light-emitting components 200 and arrange them one-to-one with the disconnection hole 1301. The first conductive element 211 and the second conductive element 212 of each light-emitting component 200 are inserted into the connecting wires 130 on both sides of the disconnection hole 1301, so that the first conductive element 211 and the second conductive element 212 are electrically connected to the positive electrode wire 110 and the negative electrode wire 120, respectively.
[0052] S220, lamp holder 220 fixed: Before or after insertion to conduct, the lamp holder 220 is installed on the lamp base 210 to conduct electrically with the first conductive element 211 and the second conductive element 212.
[0053] S300, clamping cover 300 fixation: After the insertion and conduction, the clamping cover 300 is snapped onto the side of the lamp holder 210 away from the lamp head 220, and the first conductive element 211 and the second conductive element 212 are pressed against the wire group 100 by mechanical pressure.
[0054] According to the installation method of this utility model embodiment, through a systematic process of position confirmation, insertion for conduction, fixing of lamp head 220, and fixing of clamping cover 300, efficient and reliable installation of light strings is achieved. In application, firstly, the disconnection hole 1301 is precisely opened according to the preset light-emitting position to ensure the accuracy of the conductive connection position. Then, the first conductive component 211 and the second conductive component 212 of the light-emitting component 200 are directly inserted into the connecting wires 130 on both sides of the disconnection hole 1301 to achieve electrical conduction, simplifying the traditional welding or complex plugging process. Furthermore, the lamp head 220 is connected to the conductive component through a threaded connection to ensure a stable power supply to the light source 230. Finally, the mechanical stability of the conductive connection is further enhanced by the clamping cover 300 for snap-fit fixing. The overall operation is simple, taking into account both installation efficiency and connection reliability. It is particularly suitable for the rapid deployment and maintenance of light strings in low-voltage environments, improving the user experience and the engineering applicability of the light strings.
