Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, and in particular to a high-efficiency and durable LED lamp bead. Background Technology

[0002] LED chips are solid-state light sources based on the principle of electroluminescence. Their basic structure consists of a chip of electroluminescent semiconductor material. When powered on, this chip can effectively convert electrical energy into light energy, exhibiting high luminous efficacy and a long lifespan. LED chips are not only small in size and low in energy consumption, but also generate little heat, making them widely used in various lighting and display devices and an important component of modern lighting technology.

[0003] Traditional LED chips are typically sealed by fixing the light-transmitting cover to the substrate. This installation method is not only structurally complex but also time-consuming, resulting in low installation efficiency. Furthermore, the fixing method makes disassembly during later maintenance and repair cumbersome and complicated, which may damage the LED chips and affect their normal use and lifespan. Therefore, those skilled in the art have provided a high-efficiency and durable LED chip to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-efficiency and durable LED bead. By incorporating a disassembly and assembly component, the light-transmitting cover and substrate can be quickly connected, significantly improving assembly efficiency. At the same time, the disassembly operation is also very simple and quick, improving overall operational efficiency, facilitating maintenance and repair of the LED bead, and extending its service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency and durable LED lamp bead, comprising a substrate and a light-transmitting cover, wherein a disassembly and assembly assembly is provided between the substrate and the light-transmitting cover, an outer sleeve is fixedly fitted onto the outer wall of the light-transmitting cover, and a sealing assembly is provided between the outer sleeve and the substrate;

[0006] The disassembly and assembly assembly includes a first connecting collar, which is fixedly connected to the light-transmitting cover. A first connecting groove is provided at the upper end of the substrate near the light-transmitting cover. The first connecting collar is engaged in the first connecting groove. Multiple reset grooves are provided on the inner wall of the first connecting groove. Chamfered locking blocks are movably arranged inside the multiple reset grooves. Telescopic rods are fixedly connected between the multiple chamfered locking blocks and the inner wall of the opposite end of the corresponding reset groove. Reset springs are movably sleeved on the outer wall of the multiple telescopic rods. Multiple chamfered locking grooves are provided on the inner wall of the first connecting collar.

[0007] Through the above technical solution, by providing a disassembly and assembly component, when assembling the light-transmitting cover, the first connecting collar can be directly inserted into the first connecting groove. The provided return spring and telescopic rod can cause the chamfered locking block to pop out, reset, and lock into the chamfered locking groove, thereby completing the combination connection between the light-transmitting cover and the substrate. At the same time, due to the chamfered design of the chamfered locking block and the chamfered locking groove, when it is necessary to disassemble the light-transmitting cover, only sufficient force needs to be applied to pull the light-transmitting cover out of the substrate, realizing quick disassembly and assembly, improving the overall operating efficiency, facilitating the maintenance and repair of the lamp beads, and extending the service life.

[0008] Furthermore, the sealing assembly includes a second connecting sleeve, which is fixedly connected to the outer sleeve. A second connecting groove is provided at the upper end of the substrate near the outer sleeve. A sealing ring is fixedly provided on the inner wall of the outer sleeve. A plurality of sealing protrusions are fixedly connected to the inner wall of the sealing ring. A plurality of arc-shaped grooves are provided on the outer wall of the second connecting sleeve.

[0009] Through the above technical solution, the sealing component not only enhances the tightness between the second connecting sleeve and the second connecting groove through the sealing ring, but also increases the contact area between the sealing ring and the second connecting sleeve by using the design of the sealing protrusion and the arc groove. This design effectively improves the sealing effect, ensures higher protection performance, prevents the intrusion of moisture and contaminants, thereby significantly extending the service life of the LED lamp bead and improving its overall reliability and stability.

[0010] Furthermore, a heat dissipation pad is fixedly disposed in the middle of the substrate, a die-bonding silicone is fixedly disposed at the upper end of the heat dissipation pad, a chip is fixedly disposed at the upper end of the die-bonding silicone, and gold wires are fixedly connected to both sides of the chip and the substrate.

[0011] The above technical solution effectively absorbs and disperses the heat generated by the chip by providing a heat dissipation pad, and the die-bonding silicone can both fix the chip and enhance the heat dissipation effect, reducing the performance degradation caused by overheating. The gold wires connect the chip to the substrate, ensuring efficient transmission of electrical signals.

[0012] Furthermore, the two ends of the plurality of reset springs are respectively fixedly connected to the inner wall of the opposite end of the corresponding chamfered block and the corresponding reset groove, and the plurality of chamfered blocks are engaged in the corresponding chamfered groove;

[0013] By using the above technical solution, the reset spring is effectively restricted, and multiple chamfered blocks are engaged in the corresponding chamfered slots, thereby achieving the engagement and fixation of the first connecting collar, and thus connecting and assembling the light-transmitting cover and the substrate together.

[0014] Furthermore, the second connecting sleeve is engaged in the second connecting groove, and the plurality of sealing protrusions are engaged in the corresponding arc-shaped grooves;

[0015] By employing the above technical solution, an effective sealing effect is achieved by engaging the second connecting sleeve within the second connecting groove and engaging multiple sealing protrusions within the corresponding arc-shaped grooves.

[0016] Furthermore, the outer wall of the outer sleeve is provided with a pull groove;

[0017] The above technical solution, by providing a pull groove, makes it easier for operators to pull out the light-transmitting cover.

[0018] Furthermore, the sealing ring and the plurality of sealing protrusions are all made of silicone rubber.

[0019] The above technical solution, by incorporating a sealing ring made of silicone rubber and multiple sealing protrusions, not only possesses the characteristics of high temperature resistance, low temperature resistance, UV resistance, and good elasticity, but also has excellent sealing performance, making it suitable for various environments.

[0020] This utility model has the following beneficial effects:

[0021] 1. The present invention proposes a high-efficiency and durable LED lamp bead, which, by providing a disassembly and assembly component, can quickly complete the combination and connection of the light-transmitting cover and the substrate, significantly improving assembly efficiency. At the same time, due to the chamfered design of the chamfered locking block and chamfered locking groove, when it is necessary to disassemble the light-transmitting cover, only sufficient force needs to be applied to pull the light-transmitting cover out of the substrate, realizing quick disassembly and assembly and fixing, improving overall operation efficiency, facilitating maintenance and repair of the lamp bead, and extending its service life.

[0022] 2. The present invention proposes a high-efficiency and durable LED lamp bead. The sealing component not only enhances the tightness between the second connecting sleeve and the second connecting groove through the sealing ring, but also increases the contact area between the sealing ring and the second connecting sleeve by using the design of the sealing protrusion and the arc groove.
