[0025] First, connect the device to an external controller and external circuit. Install the gear 8 inside the lamp body 2, install the lamp body 2 inside the housing 1. Take the rear shell 13, align the limit post 11 with the L-shaped groove 9, insert the limit post 11 into the L-shaped groove 9. Drive the aluminum plate 25 into the housing 1 by the rear shell 13 and connect it to the rear end of the air outlet 12.

Rotate the rear shell 13, drive the limit post 11 to rotate inside the L-shaped groove 9 by the rear shell 13 to fix the rear shell 13 inside the housing 1. When the lamp body 2 generates heat during use, the heat is transferred to the contact groove 26 through the aluminum plate 25, and then transferred to the heat sink 17 through the serpentine copper tube 18 via the contact groove 26. Turn on the cooling fan 19 to blow air on the heat sink 17 for heat dissipation. The air enters from the air inlet 10 and exits from the air outlet 12 to complete the heat dissipation operation of the LED lamp, realizing convenient elastic clamping type heat conduction and heat dissipation, and improving the heat dissipation effect;

[0026] The housing 1 is internally installed with a lamp body 2. One side of the lamp body 2 is installed with an aluminum plate 25, and the other side of the lamp body 2 is installed with multiple groups of lamp beads 27;

[0027] The side wall of the aluminum plate 25 is provided with a contact groove 26. Four groups of connecting feet 14 are installed around the aluminum plate 25.

Take the rear shell 13, align the limiting post 11 with the L-shaped groove 9, and insert the limiting post 11 into the L-shaped groove 9. The rear shell 13 drives the aluminum plate 25 into the housing 1 and connects it to the rear end of the air outlet 12. Under the sliding fit of the connecting column 16 and the spring 15, under the elastic action of the spring 15, the spring 15 drives the aluminum plate 25 to move through the connecting foot 14 and closely adhere to the rear end of the lamp body 2. Rotate the rear shell 13, and the rear shell 13 drives the limiting post 11 to rotate inside the L-shaped groove 9 to fix the rear shell 13 inside the housing 1.

The air enters from the air inlet 10 and exits from the air outlet 12 to complete the heat dissipation operation of the LED lamp. When the temperature of the LED lamp is too high and rapid heat dissipation is required, the servo motor 5 drives the drive shaft 20 to rotate. The drive shaft 20 drives the toothed ring 4 to rotate on the surface of the housing 1 through the gear 8. Under the sliding fit of the limiting ring 3 and the arc-shaped plate 6, the toothed ring 4 drives the arc-shaped plate 6 to rotate through the connecting rod 7, so as to rotate the arc-shaped plate 6 away from the air outlet 12, thereby expanding the ventilation diameter of the air outlet 12, to better dissipate and discharge the heat inside the LED lamp, and complete the use work of the LED lamp with efficient heat dissipation.
