A coolant storage cylinder 40 is installed at the top center of the LED spotlight head 10. A heat dissipating top seat 50 is installed on the top of the coolant storage cylinder 40. The LED spotlight holder 60 is connected to the top center of the heat dissipating top seat 50. The breathable water-absorbing cotton 30 is attached to the outer wall of the LED spotlight head 10, and a water-absorbing rope head 31 is arranged on the top of the breathable water-absorbing cotton 30. Figure 4 As shown, the end of the water-absorbing rope head 31 is installed with a threaded connection column 32 that is threadedly connected to the bottom of the coolant storage cylinder 40; a heat dissipation fan 52 is installed in the heat dissipation top seat 50, and the breathable water-absorbing cotton 30 is arranged between two adjacent groups of heat dissipation fins 20, which has the dual functions of water absorption and air permeability. The breathable water-absorbing cotton 30 can absorb the coolant in the coolant storage cylinder 40 and take away the heat through the evaporation of the coolant, further enhancing the heat dissipation effect. At the same time, the air permeability of the breathable water-absorbing cotton 30 ensures the smooth discharge of heat and avoids the accumulation of heat. The heat dissipation top seat 50 installed on the top of the coolant storage cylinder 40 is provided with a heat dissipation fan 52. The operation of the heat dissipation fan 52 can accelerate the air flow, further take away the heat of the LED spotlight head 10, and improve the heat dissipation efficiency. The water-absorbing rope head 31 is threadedly connected to the bottom of the coolant storage cylinder 40 through the threaded connection column 32. This connection method is not only convenient to install, but also has good sealing performance, ensuring the stability and safety of the coolant during the transmission process.

[0034] Furthermore, a fixed side seat 11 for fixing the breathable absorbent cotton 30 is also provided on the outer wall of the LED spotlight head 10.
