The extension wires of the heat conduction wires 24 intersect with the central axis of the cylindrical body 22. The heat arm 24 extends perpendicularly to both sides with a plurality of pairs of heat dissipation fins 26, and a pair of heat dissipation fins 26 are symmetric about the corresponding heat conduction arms 24, ® The length of the fins 26 gradually increases from the inside to the outside. The end of each of the heat conducting arms 24 is connected to the inner side of the outermost fins 26, so that the outermost side of each of the heat conducting arms 24 is a smooth plane on the outer side surface of the heat sink 26. The wall of the cylinder 22 projects inwardly to form three studs 23 which are evenly distributed on the inner wall of the cylinder 22, and each of the studs 23 is correspondingly disposed on the extension of the heat conducting arm 24.

The heat dissipating fins 44 extend vertically upward from the top surface of the top surface of the top plate 42 and are arranged in parallel with each other, and the height thereof is gradually reduced from the center to the outer periphery of the top plate 42. The lamp cover 50 is a hollow cylinder sized to fit the heat sink 20. The shapes of the two ends of the lamp cover 50 are matched with the shapes of the first and second receiving grooves 126 and 426, so that the two ends of the lamp cover 50 are respectively inserted into the first and second receiving grooves 126 and 426. The diameter of the lamp cover 50 is gradually reduced from the middle portion toward the both ends thereof along the axial direction thereof, so that the outer wall of the lamp cover 50 is curved integrally to change the light-emitting direction of the light-emitting diode lamp.
