However, the copper wires of the existing LED copper wire light strings are relatively thick and have a strong presence, which affects the overall beauty of the product and is difficult to adapt to more sophisticated application scenarios, limiting the use of the product. Furthermore, if the size of the copper wire is reduced, the welding point between the LED lamp and the copper wire will be reduced, increasing the difficulty of welding the LED lamp and the copper wire.

[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0019] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.
[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0021] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0022] like Figure 1-Figure 2 As shown, the utility model proposes an ultra-flexible light string, including a double parallel wire 1 and a plurality of LED chips 2. The double parallel wire 1 is provided with a plurality of welding parts 11. The welding part 11 includes a welding end surface 12 for welding with the LED chip 2. The welding end surface 12 is arranged in a plane.
[0023] It can be understood that the cross-section of the double parallel wire 1 is circular. When the LED chip 2 is welded to the wire, there is point contact between the LED chip 2 and the wire, which increases the difficulty of welding. Based on the above analysis, the utility model sets the welding end face 12 to a plane, so that the point contact between the LED chip 2 and the wire is changed to surface contact, thereby increasing the welding area, improving the stability of the welding of the LED chip 2, and allowing the LED chip 2 to be welded on a thinner copper wire, thereby reducing the overall volume of the light string, enhancing the aesthetics, and making it easier to carry. Furthermore, due to the reduced size of the copper wire, the light string can be widely used in various scenarios, such as various braiding processes, etc., thereby increasing the applicability of the light string.
[0024] Furthermore, in this embodiment, the welding end face 12 can be formed by flattening the welding portion 11 or directly flattening the double-parallel conductor 1. The double-parallel conductor 1 is a double-parallel copper wire, and the surface of the double-parallel copper wire is covered with an insulating layer. A plurality of openings are provided on the insulating layer to form the welding portion 11. In this embodiment, the openings are formed by peeling the insulating layer with a laser peeler.
[0025] Furthermore, in this embodiment, the spacings between adjacent welding portions 11 are not equal to each other. Through the above-mentioned structural setting, the utility model can realize the mounting of different distances between different LED chips on a light string to meet the process of various complex scenes, thereby improving the flexible applicability of the ultra-flexible copper wire light string.
[0026] Furthermore, in the present embodiment, the light string also includes a plurality of packaging units, which are used to package the LED chip 2. Specifically, the packaging unit is formed after the packaging glue is cured and has a variety of colors. Specifically, in the present embodiment, the packaging glue may include but is not limited to 6 colors. Through the above settings, the utility model can form LED chips that can emit different colors in a light string to enhance the beauty and interest of the product.
[0027] Furthermore, in this embodiment, preferably, the LED chip 2 is a Micro LED with a specification of 4mil*8mil and a copper wire diameter of 0.1mm-0.8mm.
[0028] Furthermore, in the present embodiment, a matte layer is provided on the surface of the encapsulation glue. The matte layer can make the light passing through the encapsulation glue softer, thereby avoiding irritation to the eyes when looking directly at the LED chip 2, and the soft light can better create an atmosphere in certain scenes. Furthermore, as an implementation method of the matte layer, a plurality of small spherical protrusions are provided on the surface of the encapsulation glue to form a matte layer. The density of the spherical protrusions is less than the density of the encapsulation glue. It can be understood that the small spherical protrusions can make the surface of the encapsulation glue rougher. When the light passes through the encapsulation glue, the light changes can be made softer under the action of refraction and diffuse reflection.
[0029] The above are one or more implementation methods provided in combination with specific content, and it is not intended that the specific implementation of the utility model is limited to these descriptions. Any method, structure, etc. similar to or identical to the method, structure, etc. of the utility model, or any technical deduction or replacement based on the concept of the utility model, shall be deemed to be within the protection scope of the utility model.
