It adopts an aspherical design to evenly distribute light and avoid local overheating. An LED downlight heat dissipation structure 2 is installed inside and outside the LED downlight body 1. A lamp cover 3 is fixedly connected to the bottom side of the LED downlight body 1.

[0033] like Figure 3 and Figure 4 As shown, the LED downlight heat dissipation structure 2 includes heat-conducting rings 23, each of which is embedded in a corresponding annular groove 11. T-shaped grooves 24 are formed on the outer side of each heat-conducting ring 23, arranged circumferentially on the outer side of the heat-conducting ring 23. Heat dissipation fins 25 are snapped onto both the upper and lower T-shaped grooves 24.
