[0002] With increasing global awareness of environmental protection and growing consumer demand for energy-saving and environmentally friendly products, LED lighting products have become increasingly popular due to their significant advantages such as high efficiency, long lifespan, and environmental friendliness. As a new type of lighting source, LED lamps have many advantages and broad application prospects. To ensure the lifespan of LED lamps, it is essential to ensure their heat dissipation.
[0003] The prior art, disclosed in CN221076402U, describes a heat dissipation structure for an LED lamp, which "includes a lamp body, with several lamp heads fixedly installed on one side of the lamp body, a lower housing fixedly installed on the other side of the lamp body, an upper housing fixedly installed on the lower housing, and a heat dissipation mechanism movably installed on the sides of the lower and upper housings. The heat dissipation mechanism includes heat dissipation fins, a heat dissipation jacket, a wedge, a first connecting plate, a second connecting plate, a connecting rod, a storage groove, a screw sleeve, and a pressure ring."
[0004] The aforementioned LED lights use heat sinks for heat dissipation, but the heat dissipation structure is relatively simple. It passively relies on the heat sinks to absorb and dissipate heat. The lamp body and lamp head are sealed, and natural air cannot circulate. Therefore, it cannot dissipate heat from the LED lights, resulting in poor overall heat dissipation. Summary of the Invention

[0015] The beneficial effects of this utility model are:
[0016] This utility model proposes an LED lamp heat dissipation structure. By incorporating heat dissipation components, a heat-conducting plate absorbs heat generated by the lamp head within the protective cover, while a heat sink dissipates the heat. A micro motor, transmission rod, gears, teeth, and a sealing disc connect the heat dissipation channels on the sealing disc surface with those on the protective cover surface, forming a complete heat dissipation channel. This ensures natural airflow, carrying away heat from the protective cover. Combined with a cooling fan, this achieves excellent heat dissipation. A filter prevents blockage of the heat dissipation channel. When the lamp head is not in use, the micro motor resets the sealing disc, sealing the heat dissipation channel and preventing impurities, humid gases, or liquids from entering.
