Description

Technical Field

[0001] This utility model relates to the field of LED string light technology, specifically an outdoor tree light with a multi-head LED integrated structure. Background Technology

[0002] Currently, outdoor tree lights, as an important component of landscape lighting and decoration, are widely used in parks, squares, roadside green belts, and residential areas. Most existing outdoor tree lights adopt a traditional structure combining LED light sources with rigid support poles, forming a tree-like shape through the combination of several fixed light strips. While these lights can achieve basic lighting and decorative functions, they still have many shortcomings in use.

[0003] Most existing tree lights use rigid encapsulation for their LED chips and circuitry, with the sheath material typically being ordinary plastic or hard resin. This lack of flexibility and transparency hinders heat dissipation during operation and makes it difficult to provide comprehensive protection for internal components. Prolonged outdoor use makes them susceptible to damage from rain or dust intrusion. Furthermore, the limited heat dissipation of the LED chips affects their lifespan, and their brightness tends to decrease over time.

[0004] Traditional tree lights typically rely on fixed metal brackets or plastic frames to maintain their overall shape. While this structure can simulate the distribution of tree branches, it lacks flexibility and adjustability. Users cannot freely bend or adjust the shape as needed, resulting in a rather monotonous overall visual effect. When it is necessary to change the shape or adjust the direction of the tree light, it is often necessary to disassemble or re-fix the bracket, which is not only complicated but also affects the ease of use.

[0005] In summary, existing outdoor tree lights generally suffer from problems such as insufficient protection, low heat dissipation efficiency, lack of flexible structural adjustment, monotonous design, and unreasonable circuit distribution. There is an urgent need for a new type of outdoor tree light structure that can simultaneously achieve flexible protection, good heat dissipation, stable power supply from multiple light sources, and arbitrary bending and shaping, in order to improve lighting stability and landscape decoration effect. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: an outdoor tree light with a multi-head LED integrated structure, including several protective sleeves, wire windings, and a counterweight base. The protective sleeves are integrally molded from flexible insulating transparent material, and internally encapsulate LED beads, heat dissipation rings, wire cores, and cables. The heat dissipation rings are partially exposed on the surface of the protective sleeves for heat dissipation. The lower ends of several protective sleeves are spirally wound and fixed into a bundle by the wire windings, forming a tree-like distribution. A splitter is installed inside the counterweight base, and the end electrodes of the LED beads are electrically connected to the splitter through cables, realizing multi-channel power supply and multi-point light source illumination.

[0008] In a preferred example, the core wire and the shaping core have the same structure, both made of metal wire or metal fiber composite material, possessing flexibility and bendability, and able to maintain their bent shape after deformation. Specifically, this design allows a single protective sheath to bend in any direction and maintain the desired shape, thereby improving the design flexibility and adjustability of outdoor tree lights.

[0009] In a preferred example, the protective sheath is made of transparent silicone or polyurethane, which combines insulation, water resistance, and flexibility. Specifically, this material provides good protection while ensuring light transmittance, allowing the tree light to maintain stable electrical performance and weather resistance during long-term outdoor use.

[0010] In a preferred embodiment, the cable winding includes a flexible loop and a shaping core. The loop, made of a flexible material, spirally wraps around several protective sheaths to achieve overall fixation. The shaping core, made of metal wire, maintains stability after overall bending and deformation. Specifically, this combined structure achieves stable shaping of individual light branches and the overall bundle, ensuring the overall stability and aesthetics of the tree light.

[0011] In a preferred embodiment, the LED beads, heat dissipation ring, wire core, and cable inside the protective sheath are sealed and formed using an integrated wrapping process, and the entire exterior is enclosed by the protective sheath. Specifically, this design not only improves the overall waterproof and dustproof rating of the product but also avoids mechanical damage caused by exposed components, thereby enhancing the lifespan and environmental adaptability of the tree light.

[0012] In a preferred embodiment, the heat dissipation ring is fitted onto the surface of the LED chip, preferably made of a high thermal conductivity alloy material, and is partially exposed on the outer surface of the cable sheath. Specifically, this structure can quickly conduct the heat generated by the LED chip during operation to the outside air, significantly improving heat dissipation efficiency and ensuring the stable luminous performance of the LED chip during long-term use.

[0013] In a preferred embodiment, the counterweight base is made of metal or engineering plastic and has an internal distributor for distributing circuits among several cables. Specifically, this structure not only provides stable support to prevent the tree light from tipping over due to outdoor wind or external forces, but also ensures simultaneous power supply to multiple light sources, enhancing the overall safety and reliability of the tree light.

[0014] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the cable sheath is integrally molded from a flexible, insulating, transparent material, internally enclosing the LED beads, heat dissipation ring, wire core, and cable, providing overall insulation, waterproofing, and protection. The LED beads are electrically connected to a distributor within the counterweight base via cables, enabling multi-channel power supply and simultaneous illumination of multiple light sources. The heat dissipation ring is partially exposed on the surface of the cable sheath, allowing for timely dissipation of the LED beads' operating heat, effectively improving heat dissipation efficiency, thereby extending the lifespan of the LED beads and ensuring lighting stability.

[0015] 2. In this invention, both the wire core and the shaping core utilize a bendable metal wire structure that retains its shape. This allows individual wire sheaths to bend freely and maintain their shape. Simultaneously, the wire winding, through the synergistic effect of the loops and the shaping core, secures several wire sheaths into a bundle, resulting in a tree-like overall arrangement. This allows for arbitrary bending and shaping of both local branches and the overall structure. This structure enables the tree light to not only provide excellent illumination but also allows for flexible adjustment of its appearance, enhancing its decorative effect.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an outdoor tree light with an integrated structure of multi-head LED beads.

[0021] Combination Figs. 1-3 As shown, the present invention provides an outdoor tree light with a multi-head LED lamp bead integrated structure, including several wire sheaths 1, wire windings 2 and counterweight bases 3.

[0022] The protective sheath 1 is integrally molded from a flexible, insulating, and transparent material, preferably transparent silicone or polyurethane, which has good waterproof, insulating, and flexible properties. The interior of the protective sheath 1, from top to bottom, sequentially encloses an LED bead 11, a heat-spreading ring 12, a wire core 13, and a cable 14. The LED bead 11 is a light-emitting diode (LED) light source, and its end electrode is connected to an external power source via the cable 14. The heat-spreading ring 12 is fitted onto the outer surface of the LED bead 11 and partially exposed on the surface of the protective sheath 1, allowing the heat generated by the LED bead 11 to be directly conducted to the outside air via the heat-spreading ring 12, ensuring effective heat dissipation. The wire core 13 is made of metal wire or metal fiber composite material, possessing flexibility and bendability, and can maintain its shape after being bent and deformed by external force, thus achieving any shape of the protective sheath 1. The cable 14 and the wire core 13 extend axially along the protective sheath 1 and continue to its lower end.

[0023] The lower ends of several protective sheaths 1 are spirally wound together and fixed by a wire winding 2, forming a tree-like radial distribution. The wire winding 2 includes a ring 21 and a shaping core 22. The ring 21 is made of flexible material and is used to wrap and fix the several protective sheaths 1 as a whole. The shaping core 22 is a metal wire structure that can maintain a stable shape after the winding is bent and deformed. This allows the lamp branches formed by multiple protective sheaths 1 to be stably fixed during the overall shaping, enhancing the structural stability of the tree lamp.

[0024] The counterweight base 3 is a metal or engineering plastic component used to support and fix the tree light as a whole, and a splitter is provided on its inner side. The splitter is electrically connected to an external power source and is used to distribute the circuit of the internal cables 14 of several protective sheaths 1, thereby ensuring that all LED beads 11 can be lit simultaneously or in groups.

[0025] In this embodiment, several protective sheaths 1 are converged into a tree-like distribution by the wire winding 2. The user can bend and shape individual protective sheaths 1 as needed. The wire core 13 can maintain its shape after bending, thereby achieving the shaping of local branches. At the same time, the shaping core 22 of the wire winding 2 can maintain its shape after the overall bending, thereby achieving the stable shaping of the overall tree-like structure. Therefore, this utility model not only has good lighting effect, but also has a high degree of plasticity and flexibility in appearance.

[0026] In another preferred embodiment, the protective sleeve 1 is integrally molded with transparent silicone. The LED 11, heat dissipation ring 12, wire core 13 and cable 14 are simultaneously sealed inside the protective sleeve 1 during the molding process, thereby improving the overall protection level and enabling the outdoor tree light to have good waterproof and dustproof performance, making it suitable for long-term outdoor use.

[0027] In another embodiment, the heat dissipation ring 12 is made of a high thermal conductivity alloy material, and its surface is in direct contact with the air, which further enhances the heat dissipation effect and ensures that the temperature of the lamp bead 11 remains stable during long-term operation.

[0028] In another embodiment, the counterweight base 3 is internally reinforced with metal components, which improves wind and impact resistance, thereby maintaining stability in outdoor environments and preventing the tree light from tipping over due to external forces.

[0029] In summary, this utility model, through the combination of a flexible protective sheath 1, a bendable and shapeable wire core 13, a wire winding 2, and a counterweight base 3, achieves integrated power supply and illumination for multi-head LED beads, while also possessing the characteristics of arbitrary bending and shaping and efficient heat dissipation, thus meeting the diverse needs of outdoor landscape lighting and decoration.
