Specific embodiments

[0028] Next, in combination with the accompanying drawings and embodiments, the specific embodiments of the present utility model will be further described in detail. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0029] Such as Figures 1 to 4As shown in the figure, a detachable LED lamp bead structure includes an LED lamp bead body 1, a positive pin 2 and a negative pin 3 respectively electrically connected to the LED lamp bead body 1, and a pin column 4, an insulating substrate 5 and a circuit board 6. Among them, the two pin columns 4 are respectively connected to the lower ends of the positive pin 2 and the negative pin 3; a power connection card slot 41 is provided on the front side of the pin column 4. The design of the power connection card slot 41 provides a physical basis for the detachable connection between the lamp bead and the circuit board 6. The insulating substrate 5 has high insulation performance, good heat conduction performance, low thermal expansion coefficient, and is resistant to high temperature, corrosion and wear. The insulating substrate 5 has a mounting groove 51 adapted to be embedded with the LED lamp bead body 1; two mounting holes 52 through which the two pin columns 4 can pass are provided on the bottom of the mounting groove 51; the circuit board 6 is provided with a corresponding number of card column grooves 61 adapted to the number of the pin columns 4; a power connection card engaging portion 62 adapted to be engaged with the power connection card slot 41 for power connection is provided in the card column groove 61; if the power connection card engaging portion 62 corresponds to the positive pin 2, it is the positive power connection card engaging portion 62, and similarly, if it corresponds to the negative pin 3, it is the negative power connection card engaging portion 62. When the lower end of the pin column 4 passes through the mounting hole 52, the power connection card slot 41 is located below the insulating substrate 5, the card column groove 61 is adaptively nested on the pin column 4, and the power connection card engaging portion 62 is adaptively engaged with the power connection card slot 41 for power connection to achieve electrical connection. The circuit board 6 is detachably connected to the insulating substrate 5 closely against the bottom surface of the insulating substrate 5. By designing the connection mode of the circuit board 6 and the insulating substrate 5 in this way, a connection mode that is both stable and easy to separate is formed between the LED lamp bead body 1 and the circuit board 6. When it is necessary to replace the LED lamp bead body 1, simply operate to disengage the power connection card engaging portion 62 from the power connection card slot 41, and then easily remove the damaged LED lamp bead body 1 and replace it with a new LED lamp bead body 1, which greatly improves the maintenance efficiency.

[0030] The detachable LED lamp bead structure is designed by combining an LED lamp bead body 1, a positive electrode pin 2, a negative electrode pin 3, a pin post 4, an insulating substrate 5 and a circuit board 6. The key point lies in the special design of the pin post 4 and the circuit board 6. Specifically, the LED lamp bead body 1 is adaptively embedded in the installation groove 51. After the lower end of the pin post 4 passes through the installation hole 52, the clamping post groove 61 on the circuit board 6 is adaptively nested on the pin post 4, and the power connection clamping part 62 is adaptively clamped and electrically connected with the power connection clamping groove 41 to energize the LED lamp bead body 1. Moreover, the circuit board 6 is closely attached to the bottom surface of the insulating substrate 5 and is detachably connected to the insulating substrate 5, realizing the detachable connection between the LED lamp bead body 1 and the circuit board 6, solving the problem of difficult replacement of lamp beads in traditional LED lamps. This design not only simplifies the maintenance process, reduces the maintenance cost, but also reduces the overall replacement of LED lamps, promoting the recycling of resources and conforming to the development trend of green lighting.

[0031] Preferably, the positive electrode pin 2 and the pin post 4, and the negative electrode pin 3 and the pin post 4 are integrally formed. Such a design can improve the connection stability of the structure, with high production efficiency. It can not only improve the power-on reliability of the circuit but also reduce costs.

[0032] In this embodiment, the positive electrode pin 2 and the negative electrode pin 3 are two identical conductive pins; the width of the pin post 4 in the front-back direction is 2-3 times the width of the positive electrode pin 2 in the front-back direction. Such a design can enhance the stiffness and strength of the pin, making it not easily deformed. After designing the power connection clamping groove 41, it is adaptively installed with the power connection clamping part 62, and the power-on of the LED lamp bead body 1 is more stable.

[0033] In order to more easily form the power connection clamping groove 41, the pin post 4 is a square post. The structure is flat, making it easier to form the power connection clamping groove 41. After being adaptively installed with the clamping post groove 61, the structure is more stable and not easily loosened, which is beneficial to enhancing the power-on stability of the LED lamp bead body 1.

[0034] In this embodiment, a latch groove structure 7 adapted to the left side, right side and rear end of the circuit board 6 is provided at the bottom end of the insulating substrate 5. By providing the latch groove structure 7 to be adapted and snap-fitted with the circuit board 6, a detachable connection between the circuit board 6 and the insulating board is realized, with a simple structure and convenient disassembly and assembly. Specifically, the latch groove structure 7 includes a left L-shaped groove body 71, a right L-shaped groove body 72 and a rear L-shaped groove body 73; the left L-shaped groove body 71, the right L-shaped groove body 72 and the rear L-shaped groove body 73 are respectively connected to the left bottom end, right bottom end and rear bottom end of the insulating substrate 5; the rear end of the left L-shaped groove body 71 and the rear end of the right L-shaped groove body 72 are respectively communicated with the left side and the right side of the rear L-shaped groove body 73. Further, on the basis of designing the latch groove structure 7, a bolt 8 is additionally provided to further enhance the connection stability between the insulating substrate 5 and the circuit board 6. Specifically, the bolt 8 can pass through the latch groove structure 7, the circuit board 6 and be connected to the insulating substrate 5. Of course, in another embodiment, when the insulating substrate 5 and the circuit board 6 are connected by the bolt 8, the bolt 8 can directly replace the latch groove structure 7, and the circuit board 6 and the insulating substrate 5 can be directly detachably connected by the bolt 8.

[0035] In order to enhance the brightness of the LED lamp bead structure, a plurality of the mounting grooves 51 are uniformly arranged along the length direction of the insulating substrate 5; the number of the LED lamp bead bodies 1 is the same as the number of the mounting grooves 51. By designing the mounting grooves 51 in this way, the corresponding LED lamp bead bodies 1, the positive electrode pins 2, the negative electrode pins 3, the pin columns 4 corresponding to the positive electrode pins 2 and the negative electrode pins 3 and other related structures are also designed accordingly. By increasing the number of the LED lamp bead bodies 1, the purpose of enhancing the brightness of the LED lamp bead structure is achieved.

[0036] In summary, the embodiment of the present invention provides a detachable LED lamp bead structure. Among them, the detachable LED lamp bead structure is designed by combining the LED lamp bead body 1, the positive electrode pin 2, the negative electrode pin 3, the pin column 4, the insulating substrate 5 and the circuit board 6. The key point lies in the special design of the pin column 4 and the circuit board 6, which is manifested in that the LED lamp bead body 1 is adaptively embedded in the mounting groove 51, and after the lower end of the pin column 4 passes through the mounting hole 52, the card column groove 61 on the circuit board 6 is adaptively nested on the pin column 4, and the power connection card-embedding part 62 is adaptively card-embedded and electrically connected with the power connection card-embedding groove 41 to realize the power-on of the LED lamp bead body 1. And the circuit board 6 is closely attached to the bottom surface of the insulating substrate 5 and is detachably connected to the insulating substrate 5, realizing the detachable connection between the LED lamp bead body 1 and the circuit board 6, solving the problem of difficult replacement of the lamp beads in the traditional LED lamps. This design not only simplifies the maintenance process, reduces the maintenance cost, but also reduces the overall replacement of the LED lamps, promotes the recycling of resources, and conforms to the development trend of green lighting.

[0037] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present application.
