[0027] The following description will be made in conjunction with the accompanying drawings Figures 1-4 Further detailed description of the present application,

[0028] The embodiment of the present application discloses a LED lamp circuit board power module, including U-shaped base 1 and cover plate 3, the inner bottom wall of U-shaped base 1 is placed with integrated circuit board power module 2; the cover plate 3 is covered on the top of U-shaped base 1 and cooperates with U-shaped base 1 to form the containing cavity 4 for placing integrated circuit board power module 2;

[0029] Four groups of pressing columns 5 provided on the bottom of cover plate 3 press and fix integrated circuit board power module 2 on U-shaped base 1, and the connecting plates 6 at four corners of cover plate 3 are inserted into the inner side of U-shaped base 1, and the connecting plates 6 are buckled with U-shaped base 1 through buckling columns 7.

[0030] The pressing column 5 includes the pressing rod 51 fixed on the bottom of the cover plate 3, the insertion rod 52 fixed on the bottom of the pressing rod 51 and penetrating the mounting hole A8 on the integrated circuit board power module 2 and inserted into the positioning groove 9 on the U-shaped base 1, and the rubber gasket 53 sleeved on the outer side of the insertion rod 52 and limited between the pressing rod 51 and the integrated circuit board power module 2. The pressing rod 51 is combined with the positioning groove 9 of the U-shaped base 1 through the insertion rod 52, which provides a stable support point to ensure that the circuit board power module cannot move in the U-shaped base 1. The addition of the rubber gasket 53 can provide buffering between the pressing rod 51 and the integrated circuit board power module 2, reducing damage caused by vibration. The rubber gasket 53 can also improve the stability of the pressing. So that the power module can be easily removed or replaced from the system, which is helpful for maintenance and upgrading.

[0031] The two sides of the U-shaped base 1 are provided with heat dissipation holes A10. The heat dissipation holes A10 allow air to circulate, which helps to extract heat from the power module, reduce the internal temperature and prevent overheating. Through effective heat dissipation, the life of the circuit board and the LED lamp can be prolonged, because high temperature is one of the main reasons leading to the aging of electronic components. Better heat dissipation performance helps to maintain the efficiency and light output of the LED lamp, because temperature rise will cause light efficiency to decrease. Four mounting holes B11 are provided at the four corners of the bottom of the U-shaped base 1. The mounting holes B11 allow the entire U-shaped base 1 to be fixed to other structures or devices, simplifying the installation process. Through the mounting holes B11, screws or other fixing members can be used to firmly install the U-shaped base 1 at the required position, increasing the stability of the entire system.

[0032] The connecting plate 6 is provided with a through hole 12, and the U-shaped base 1 is provided with a hidden screw hole 13. The buckle column 7 includes a plug column penetrating through the hidden screw hole 13 and the through hole 12 and provided with a circular groove 71, a hexagonal cap 72 fixed on the plug column and located away from one end of the circular groove 71 and limited in the hidden screw hole 13, a support plate 73 fixed in the circular groove 71, a guide plate 75 cooperating with the circular groove 71 to form a guide groove 74, a buckle plate 77 slidingly guided by the guide groove 74 and movably penetrating through a guide hole 76 on the plug column, a push plate 78 fixedly connected with the buckle plate 77, and a plurality of springs 79 fixed between the buckle plate 77 and the support plate 73. One end of the plug column away from the hexagonal cap 72 is provided with a circular sealing plate 710, and the circular sealing plate 710 is provided with a rectangular notch 711 penetrating and guiding the push plate 78.

By pushing the push plate 78 downward to compress the springs 79, the buckle plate 77 is hidden in the circular groove 71 downward, thereby releasing the buckling of the cover plate 3 and the U-shaped base 1.

[0034] The design of the hidden screw hole 13 makes the screw not easy to be seen, improving the appearance and overall design of the product. The design of the buckle column 7 penetrating through the hidden screw hole 13 and the through hole 12 can provide more stable connection and prevent loosening. The design of the guide plate 75 and the guide groove 74 helps the buckle plate 77 to accurately align and slide, improving the accuracy and efficiency of assembly. The hexagonal cap 72 and the support plate 73 increase the stability of the connection, and the plurality of springs 79 provide appropriate elastic force to ensure the fastening of the buckling. The design of the push plate 78 allows users to release the buckling by simple pushing operation, facilitating maintenance and disassembly.

[0035] The circular sealing plate 710 can protect the internal structure and prevent dust and moisture from entering. The design of the rectangular notch 711 allows the push plate 78 to easily penetrate and guide, simplifying the unlocking process. By pushing the push plate 78 downward to release the buckling, the cover plate 3 is easily opened, making it more convenient to maintain and replace the integrated circuit board power module 2.

The design of the heat dissipation holes B14 increases air circulation and improves heat dissipation efficiency, which helps to maintain the working temperature of the integrated circuit board power module 2 of the LED lamp. Through effective heat dissipation, the service life of the LED lamp can be prolonged, and the failure caused by overheating can be reduced.

[0037] The LED lamp circuit board power module, the pressing column 5 firmly presses and installs the integrated circuit board power module 2 on the U-shaped base 1 through pressure, prevents the circuit board from displacement or falling off due to vibration during transportation or use, the pressing column 5 can protect the circuit board from external impact, improves the stability and durability of the whole power module, the pressing column 5 can replace the traditional screw to fix the integrated circuit board power module 2, facilitates the installation and fixing of the integrated circuit board power module 2 and disassembly and maintenance;

[0038] The buckle column 7 is buckled with the U-shaped base 1 through the connecting plate 6, so that the cover plate 3 and the U-shaped base 1 are tightly connected, and the structural stability of the whole power module is ensured. The buckle column 7 makes the connection of the cover plate 3 and the U-shaped base 1 more convenient, improves the production efficiency, reduces the assembly difficulty, and facilitates the removal of the buckle column 7, releases the buckling of the cover plate 3 and the U-shaped base 1, and facilitates the removal of the integrated circuit board power module 2 for maintenance.
