[0002] LED lighting is a lighting device that uses light-emitting diodes (LEDs) as light sources. LED lighting has a wide range of applications and can perform well in different fields.

[0003] Because LEDs generate heat during operation, good heat dissipation design is crucial to ensuring the lifespan and performance of LED lamps. Conventional LED lighting fixtures typically use passive cooling through metal casings or heat conduction through heat sink fins. However, these cooling methods neglect convection cooling, resulting in a lack of effective heat dissipation across the lamp's surface area, resulting in poor cooling performance.
