Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figures 1-4 An LED power driver includes a driver body 1. The driver body 1 has a rectangular structure and is made of aluminum alloy, which has good heat dissipation performance. Multiple heat dissipation holes are evenly opened on the front and rear sides of the driver body 1. The diameter of the heat dissipation holes is 5mm and the spacing between the holes is 10mm to ensure smooth airflow and effectively reduce the internal temperature of the driver. Input and output line interfaces are respectively provided on both sides of the driver body 1. The input interface is connected to the external power supply through a three-core cable, and the output interface is connected to the LED light through a two-core cable.

[0026] Two side plates 2 are fixed parallel to each other on both sides of the driver body 1. The side plates 2 are made of the same aluminum alloy as the driver body 1 and are fixed together with screws. Two through holes are drilled on each side of the bottom of the side plates 2 for mounting the columns 3. The columns 3 are made of stainless steel. The tops of the four columns 3 pass through the bottom sides of the two side plates 2 respectively and are fixed with nuts to ensure that the columns 3 are tightly connected to the side plates 2. Two rectangular plates 4 are fixedly connected through the bottom and top ends of the columns 3, ensuring that the two rectangular plates 4 are 30mm away from the driver body 1. Air inlets are provided on the rectangular plates 4. The diameter of the air inlet 10 is 80mm. The cooling fan 11 is fixed to the inside of the rectangular plate 4 with bolts. The diameter of the cooling fan 11 matches the air inlet 10 to ensure that air can enter smoothly from the air inlet 10 and accelerate the flow through the cooling fan 11 to improve the heat dissipation efficiency. On the outside of the rectangular plate 4, the mounting frame 8 is fixed with bolts. The mounting frame 8 is made of plastic and has a filter 9 on its inner wall. The filter 9 is made of nylon and has a pore size of 0.5mm to effectively filter the air at the air inlet of the cooling fan and reduce the impact of dust on the cooling fan 11 and the driver body 1.

[0027] Mounting plate 5 is fixed to both sides of the two rectangular plates 4 on the opposite side by bolts. Mounting plate 5 is L-shaped to ensure that there is a gap between the rectangular plates 4 and the mounting plane, which facilitates heat dissipation and air intake through the air inlet 10.

[0028] An LED lamp includes a lamp body 7, with multiple LED beads 17 evenly fixed at the bottom of the lamp body 7. The LED beads are surface-mount packaged and have a power of 1W. The lamp body 7 is connected to the output interface of the driver body 1 through a waterproof cable to ensure a stable power supply.

[0029] Side frames 12, made of aluminum alloy, are provided on both sides of the lamp body 7. Positioning rods 14 are fixed to the inner walls of the bottom two sides of the side frames 12. The two sides of the adjustment plate 15 are slidably connected to the inner walls of the side frames 12 and limited by the positioning rods 14. A threaded post 13 is provided at the center of the side frame 12. The bottom and top of the threaded post are rotatably connected to the inner wall of the side frame 12 through bearings. The adjustment plate 15 has a threaded hole and is threadedly fitted with the threaded post 13. The up and down position of the adjustment plate 15 is adjusted by rotating the rotating handle at the top of the threaded post 13. Then, the lampshade is fixed below the adjustment plate 15. The position of the adjustment plate 15 is adjusted by rotating the rotating handle, so that the distance between the lamp bead 17 and the lampshade can be adjusted. In this way, stepless adjustment can be achieved by rotating the rotating handle to adjust the distance between the lamp bead 17 and the lampshade. When the lamp bead 17 is close to the lampshade, the light intensity is higher, and when the lamp bead 17 is far away from the lampshade, the light intensity is lower, thus meeting different lighting needs.

[0030] A second mounting plate 16 is fixed to the bottom of the outer side of the side frame 12. The mounting plate is made of steel plate with a thickness of 3mm. Each mounting plate has three second mounting holes with a diameter of 6mm, which facilitates fixing the lamp body 7 to the ceiling or bracket with screws.
