Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED lamp bead technology, specifically to an LED lamp bead unit that can be cut into LED circuit boards. Background Technology
[0002] LED LED beads are a new type of decorative light, supplementing linear light sources and floodlighting. They are intelligent lights that can replace displays of a certain size by achieving a point-to-surface effect through pixel color mixing. Pixel pitch: the distance from the center of one pixel to the center of another, also known as "P-", such as P3, P6, etc. Pixel density is reflected in the distance between pairs of pixels; pixel pitch and pixel density are physical characteristics of a display screen. Information capacity is the unit of information that can be displayed per unit area of pixel density. The smaller the pixel pitch, the higher the pixel density, the more information can be displayed per unit area, and the closer the suitable viewing distance. The larger the pixel pitch, the lower the pixel density, the less information can be displayed per unit area, and the farther the suitable viewing distance. Because LEDs are close to "point" light sources, the design of lighting fixtures is relatively convenient; however, when used for large-area displays, the current and power consumption are relatively high. LEDs are generally used in electronic devices such as indicator lights, digital tubes, display panels, and optocouplers. They are also commonly used in optical communication and decoration of building outlines, amusement parks, billboards, streets, stages, and other places. Currently, LED lamp bead units are prone to high temperatures during long-term operation. High temperature is a fatal flaw of semiconductor devices. Excessive temperature will reduce the service life of LED lamp bead units and cause damage. Utility Model Content
[0003] The purpose of this invention is to provide an LED bead unit that can cut LED circuit boards, which solves the problem that current LED bead units are prone to high temperatures during long-term operation. High temperature is a fatal flaw of semiconductor devices, and excessively high temperature will cause the LED bead unit to reduce its service life and be damaged.
[0004] Technical solution
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an LED bead unit for cutting LED circuit boards, comprising an LED bead structure, wherein the bottom of the LED bead structure is fixedly connected to a bead solder foot, the outer surface of the LED bead structure is fixedly connected to a mounting ring, the outer surface of the LED bead structure is sleeved with a heat transfer ring, the lower surface of the heat transfer ring is fixedly connected to a cooling fin structure, the number of cooling fin structures is two, and a connecting frame is fixedly connected between the two cooling fin structures.
[0006] Furthermore, the lower surface of the heat transfer ring overlaps with the upper surface of the mounting ring.
[0007] Furthermore, the upper surface of the mounting ring is provided with a combined slot structure, and a combined positioning block is engaged inside the combined slot structure.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] like Figure 1-2 As shown, this utility model embodiment provides an LED lamp bead unit with a cuttable LED circuit board, including an LED lamp bead structure 1. The bottom of the LED lamp bead structure 1 is fixedly connected to a lamp bead solder foot 2. The outer surface of the LED lamp bead structure 1 is fixedly connected to a mounting ring 3. A heat transfer ring 4 is sleeved on the outer surface of the LED lamp bead structure 1. The lower surface of the heat transfer ring 4 overlaps with the upper surface of the mounting ring 3. A combined slot structure 6 is opened on the upper surface of the mounting ring 3. A combined positioning block 5 is snapped into the inside of the combined slot structure 6. The upper surface of the combined positioning block 5 is fixedly connected to the lower surface of the heat transfer ring 4. A cooling fin structure 7 is fixedly connected to the lower surface of the heat transfer ring 4. There are two cooling fin structures 7. A connecting frame 8 is fixedly connected between the two cooling fin structures 7.
[0018] Working principle: After the LED bead structure 1 is soldered onto the circuit board, the heat transfer ring 4 is placed on the surface of the LED bead structure 1 and pushed downwards, so that the heat transfer ring 4 drives the combined positioning block 5 to be inserted into the combined slot structure 6, thereby completing the installation of the cooling fin structure 7. When the LED bead structure 1 generates temperature, the temperature will be absorbed and dissipated by the heat transfer ring 4 and transferred to the cooling fin structure 7 and the connecting bracket 8 for heat dissipation.
