Beschreibung
Zusammenfassung:	The utility model discloses a switch power supply of a light-emitting diode (LED) mining lamp, which comprises a power supply box, a circuit board, a heat conduction silicon sheet, a transformer and a heat dissipation device, wherein the power supply box comprises an upper shell and a lower cover, the upper shell comprises a top cover and a side plate, the transformer and the heat dissipation device are fixed on the circuit board, the shape of the top surface of the heat dissipation device is matched with the shape of the bottom surface of the top cover of the upper shell of the power supply box, and the heat conduction silicon sheet is clamped between and closely attached to the top surface of the heat dissipation device and the bottom surface of the top cover of the upper shell. The switch power supply simultaneously adopts the heat dissipation mode of air heat convection and heat conduction to dissipate heat to the outside, so the heat dissipation efficiency of the switch power supply of the LED mining lam
