[0030] The following is in conjunction with the appendix Figures 1 to 9 This utility model will be described in detail.

[0031] This utility model is an umbrella-shaped outdoor decorative light string, including a light string wire 1, one end of which is electrically connected to a female connector 2, and the other end is electrically connected to a male connector 3; multiple lamps 4 are connected in parallel in the middle of the light string wire 1, each lamp 4 including a lamp holder 5, a bulb 6, and an umbrella-shaped decorative shell 7; the lamp holder 5 is electrically connected to the light string wire 1, and the lamp holder 5 includes an integrally injection-molded plug 51 and an external threaded seat 52, the plug 51 having at least two electrical sockets 511, and conductive terminals 512 installed inside the electrical sockets 511; The plug-in socket 51 is also provided with an annular groove 513 at one end near the external threaded seat 52; the bulb 6 includes a bulb shell 61, a light-emitting core 62, and a connecting bracket 63; the light-emitting core 62 is installed inside the bulb shell 61, and the light-emitting core 62 includes at least a first metal wire 621, a light-emitting body 622, and a second metal wire 623 that are electrically connected in sequence; the connecting bracket 63 is fixedly installed at the opening of the bulb shell 61, and a slot 631 with an opening is also provided in the middle of the connecting bracket 63, and a plurality of hooks 632 are provided at the opening end of the slot 631; Figure 3As shown, the first metal wire 621 and the second metal wire 623 extend into the slot 631 to form a metal pin 624. The metal wire of the metal pin 624 has a larger diameter and higher strength, which is more conducive to electrical connection with the socket 51. When assembling the lamp 4, the top of the umbrella-shaped decorative shell 7 is provided with an umbrella assembly opening 71. The umbrella assembly opening 71 extends inward to provide an internal thread seat 72. The internal thread seat 72 is threadedly connected to the external thread seat 52. Then, the socket 51 can be inserted into the slot 631 and the metal pin 624 can be inserted into the electrical socket 511. At the same time, the hook 632 and the annular groove 513 are interlocked and fixedly assembled to connect the mounting bracket 63 and the socket 51. Thus, the entire lamp 4 is assembled.

[0032] Compared with traditional lamps, this utility model has the following advantages: 1. This utility model integrally injection molds an external threaded seat above the lamp holder, and the umbrella-shaped decorative lampshade is assembled on the lamp holder through a threaded connection. This eliminates the need for multiple injection molding of two lamp holders and for assembling the lamp holders, saving raw materials and simplifying the molding process, thereby effectively reducing the overall manufacturing cost of the lamp string; 2. This utility model improves the connection method between the bulb and the lamp holder from a threaded connection to a positioning plug-in connection. This not only improves the assembly efficiency but also eliminates the need for a large metal threaded lamp head. Only a small connecting terminal is needed for electrical connection, which also helps to reduce the overall manufacturing cost of the lamp string.

[0033] As an example, such as Figure 1 As shown, the lamp holder 5 is electrically connected to the string light conductor 1 via a lamp conductor 53. A lamp connector 54 is fitted over the connection between the lamp conductor 53 and the string light conductor 1. The lamp conductor 53 allows the lamp 4 to hang vertically. The lamp connector 54, besides protecting the electrical connection between the string light conductor 1 and the lamp conductor 53, also has a hanging lug at its top for easy outdoor hanging. In this invention, the electrical connection between the lamp conductor 53 and the string light conductor 1 is as follows... Figure 5 As shown, the lamp wire 53 is equipped with two-stage wires. The two-stage wires of the lamp wire 53 are connected in parallel with the two-stage wires of the lamp string wire 1 through connecting terminals (the positive terminal of the lamp wire 53 is connected in parallel to the negative terminal of the lamp string wire 1, and the negative terminal of the lamp wire 53 is connected in parallel to the positive terminal of the lamp string wire 1), thereby realizing the connection of the lamp 4 in parallel to the lamp string wire 1.

[0034] This invention relates to a string of lights primarily used for outdoor gatherings or garden decorations. To improve the lifespan of the string of lights, the inventors have installed a sealing ring 633 on the inner bottom of the slot 631, and a limiting step 514 adapted to the sealing ring 633 is provided at the front end of the plug-in 51. When the plug-in 51 is fully inserted into the slot 631, the sealing ring 633 is pressed against the limiting step 514, sealing the connection gap between the plug-in 51 and the connecting bracket 63, thereby improving the waterproofness of the electrical connection of the light fixture 4 and preventing external moisture from entering the connecting bracket 63 even in extreme outdoor weather.

[0035] To improve the assembly efficiency of the connector 51 and the connecting slot 63, the outer wall of the connector 51 is provided with a strip-shaped positioning post 515, and the connecting slot 63 is provided with a positioning notch 634 that matches the strip-shaped positioning post 515. The assembly of the connector 51 and the connecting slot 63 is positioned by the strip-shaped positioning post 515 and the positioning notch 634, allowing assemblers to quickly identify the correct assembly position of the connector 51. This prevents mis-insertion of the four electrodes of the lamp and effectively improves assembly efficiency. Simultaneously, the positioning notch 634 provides a certain buffer space when the connector 51 is inserted into the slot 631, further facilitating the assembly of the connector 51 and the connecting slot 63.

[0036] Preferably, the light-emitting core 62 further includes a waterproof adhesive base 625, which is tightly fitted to the inner side of the opening of the bulb 61. The waterproof adhesive base 625 is provided with at least two wire-receiving holes for metal wires to pass through. The waterproof adhesive base 625 serves both as a supporting component for the light-emitting lamp body 622 and as an assembly at the opening of the bulb 61, sealing the bulb 6 and improving its waterproof performance. The light-emitting core 62 of this invention can be adopted as follows... Figure 9 The light-emitting core 62 shown can also be a common core as described in the prior art CN202320936040.1. Since the core structure is prior art, the structure of the light-emitting core 62 will not be described in detail here.

[0037] As one embodiment, the string light conductor 1 includes a positive wire 11, a negative wire 12, and an insulating layer 13 covering the positive wire 11 and the negative wire 12.

[0038] To further improve the technical solution and enhance the decorative effect of the lamp 4, the string wire 1 also includes an LED light-emitting core wire 14, enabling the string wire to emit light synchronously while the lamp 4 is emitting light. Through intelligent control, the light emission frequency of the string wire can also correspond to that of the lamp 4, significantly improving the decorative effect of the string. The LED light-emitting core wire 14 includes a light-emitting conductor 15 and a plurality of LED beads 16 evenly distributed on the light-emitting conductor 15; wherein, the LED beads 16 are encapsulated with epoxy resin, and the shape and position of the LED beads 16 are solidified after epoxy resin encapsulation, effectively preventing the beads from falling off.

[0039] In the aforementioned LED light-emitting core wire 14, the light-emitting conductor 15 includes a positive electrode core wire 17 and a negative electrode core wire 18, wherein the end of the positive electrode core wire 17 is connected in parallel with the negative electrode wire 12, and the end of the negative electrode core wire 18 is connected in parallel with the positive electrode wire 11, thereby electrically connecting the LED light-emitting core wire 14. Then, the LED light-emitting core wire 14, the positive electrode wire 11, and the negative electrode wire 12 are twisted into a single strand and then covered with a transparent insulating layer 13.

[0040] To further improve the luminous effect of the 4-core wire of the lamp, the positive wire 11, the negative wire 12, and the LED light-emitting core wire 14 are twisted into a single strand and then wrapped with a transparent wrapping film 19. The transparent wrapping film 19 is made of polypropylene material. The formed wrapping film is transparent and has high ductility and excellent processability. At the same time, it has high scattering performance, which facilitates further scattering of the light from the LED light-emitting core wire 14.

[0041] In this technical solution, the insulating layer 13 is made of semi-transparent PVC material. The molded insulating layer 13 is light-transmitting and works in conjunction with the transparent wrapping film 19 so that the light emitted by the LED light-emitting core wire 14 can pass through the insulating layer 13 and further diffuse outward to form the light-emitting wire 15 of the light string.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
