[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, if there are words such as "several", they mean one or more, "multiple" means two or more, "greater than", "less than", "exceeding" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Therefore, refer to Figures 1 to 2 The present invention provides an LED light strip with the following embodiment:

[0027] An LED light strip includes a PCB board 100, a plurality of LED beads 200 and a plurality of constant current control elements 300. The PCB board 100 is elongated, and the plurality of LED beads 200 are evenly distributed on the PCB board 100. The constant current control elements 300 are arranged between adjacent beads.

[0028] The elongated PCB board 100 refers to a circuit board whose length is much greater than its width. It can be made of glass fiber reinforced epoxy resin material and can support electronic components and form conductive paths. The uniform distribution of LED beads 200 means that they are arranged at fixed intervals on the PCB board 100. They can be fixed using surface mount packaging technology to ensure uniform light distribution in the light-emitting area. A constant current control element 300 is disposed between adjacent LED beads 200 to regulate the current flowing through the beads.

[0029] Specifically, each constant current control element 300 independently controls the current of its corresponding section. When the power supply voltage drops during long-distance transmission, it can automatically adjust the output current value. The equally spaced LED beads 200, combined with the segmented management of the constant current control element 300, ensure that each segment of beads operates under the same current conditions, effectively extending the maximum usable length of the light strip.

[0030] Compared to existing technologies, traditional LED strips use a single power supply line and lack a current regulation mechanism, resulting in decreased brightness of the end LEDs due to insufficient voltage. This solution utilizes a segmented constant current control element 300 to achieve automatic current compensation while maintaining a simple circuit structure, eliminating the need for complex external control equipment and ensuring uniform light brightness. The integrated design allows for direct installation and use of the LED strip, eliminating the secondary processing steps required by traditional solutions. The constant current control element 300 used in this application is compatible with most application solutions, requiring no secondary design changes. It can directly replace the original resistor package, achieving precise current control and regulation, avoiding LED damage and uneven brightness caused by current fluctuations. Furthermore, with silicone sleeve protection, it achieves an IP65 waterproof and dustproof rating, meeting the requirements of most indoor and outdoor scenarios and environments.

[0031] This application further proposes that the PCB board 100 is wrapped with an insulating layer 120. The insulating layer 120 refers to a non-conductive material layer covering the outer surface of the PCB board 100, which can be implemented using a silicone component. This material layer completely wraps the surface and edges of the PCB board 100. "Wrapping" refers to the process of injection molding or dip coating to ensure the insulating material completely covers the outer peripheral surface of the PCB board 100. Specifically, a thermoforming process can be used to ensure a tight bond between the silicone material and the PCB board 100. With the protection of the silicone sleeve, an IP65 waterproof and dustproof rating can be achieved, meeting the requirements of most indoor and outdoor scenarios and environments.

[0032] A further proposed LED light strip is described, in which the PCB board 100 comprises multiple sequentially connected PCB units. These multiple sequentially connected PCB units refer to the PCB board 100 being divided into multiple independent and detachably connectable modular structures. Adjacent PCB units are connected by solder components 110. This segmented design facilitates adjustment of the light strip length according to actual needs. In this embodiment, each PCB unit includes six LED beads 200 and a constant current control element 300, with the constant current control element 300 located in the middle of each PCB unit.

[0033] This application further proposes that the PCB board 100 is connected to two input / output lines 400. The input / output lines 400 are wires used to connect to an external power source, specifically copper core wires with insulated sheaths, serving to transmit external power to the PCB board 100.

[0034] Furthermore, PCB board 100 is a flexible board. A flexible board refers to a circuit board made of bendable materials, specifically polyimide substrate or polyester film substrate, possessing bendable and deformable characteristics. In the light strip structure, the flexible board achieves bending capability through material selection and lamination processes, allowing the light strip to adapt to the curvature requirements of different installation scenarios and avoiding the breakage risk caused by rigid structures.

[0035] Specifically, the flexible board, through its physical properties, allows the LED strip to conform to curved surfaces or confined spaces during installation, such as bending into circular or wavy paths. The constant current IC and LED chips 200 are fixed to the flexible board using surface mount technology, further reducing the risk of component detachment due to deformation. In some other embodiments, the PCB board 100 is a rigid PCB board 100.

[0036] This application further proposes that the PCB board 100 is a single-sided board. A single-sided board refers to a printed circuit board with conductive lines arranged on only one side. Specifically, this can be achieved by copper plating on one side of an insulating substrate and etching to form the conductive lines. The single-sided board structure simplifies the manufacturing process, reduces interlayer alignment errors, thereby improving production efficiency and yield. Simultaneously, single-layer wiring avoids the interlayer peeling problems that may occur when multilayer boards are bent, enhancing the structural reliability of the light strip during installation and use.

[0037] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
