[0052] In conclusion, the mine lamp separates the power supply part 100 and the light source part 200, avoids the heat generated by the light source part 200 from being transmitted to the power supply part 100, increases the heat dissipation pressure of the power supply part 100, the light source part 200 is provided with the air hole 220 in the circumference, the end 111 of the side heat dissipation fin 110 connected with the light source part 200 is located in the same vertical plane with the air hole 220, the flowing air passing through the air hole 220 can quickly take away the heat dissipated by the side heat dissipation fin 110, thereby improving the heat dissipation efficiency of the power supply of the mine lamp, and preventing the mine lamp from being overheated to cause fire.
