When the air enters the interior of the lamp cover 1, it will be filtered by the internal filter cartridge 8, so that the filter cartridge 8 can filter the dust carried by the air, thereby preventing the dust from adhering to the surface of the heat-conducting column 5. Then, the rotating motor 102 and the transmission motor 121 are started, so that the transmission motor 121 can drive the transmission rod 122 to rotate after being started, so that the transmission rod 122 can drive the vibration cam 11 to rotate after rotating, so that the vibration cam 11 rotates. After that, the inner wall of the filter cartridge 8 can be knocked, so that the dust attached to the filter cartridge 8 will be separated from the filter cartridge 8 after being vibrated, and then fall down and be discharged through the dust discharge port 14. At the same time, the rotating motor 102 can drive the gear 103 to rotate after being started, so that after the gear 103 rotates, it can drive the mounting ring 9 to rotate through the teeth 101 meshing with the gear 103, so that the mounting ring 9 can drive the filter cartridge 8 to rotate, so that the filter cartridge 8 rotates while being knocked by the vibration cam 11, so that the dust on the surface of the filter cartridge 8 can be cleaned, thereby achieving the effect of auxiliary dust cleaning and heat dissipation.

[0036] In summary, this LED automobile lamp that is easy to dissipate heat, by setting a filter cartridge 8, enables the filter cartridge 8 to filter the air entering the interior of the lamp cover 1 through the ventilation holes 7, thereby solving the problem of dissipating heat to the spiral cooling tube on the heat-conducting column through the heat-dissipating fan blades during use. However, the ventilation holes are not provided with a filtering structure, so that the external air will carry dust into the interior of the lamp cover shell, and the adhesion of dust will reduce the heat dissipation effect of the heat-conducting column and the spiral cooling tube, thereby having certain limitations.
