Further, a plurality of fins 112 is formed axially around the outer circumference of heat sink part 11. A plurality of annular grooves 113 are formed in a radial direction around the outer circumference of heat dissipation part 11. Further, a plurality of convection vents 114 are axially formed in the heat dissipation part 11 around the thru hole 111 for heat convection and heat dissipation acceleration.
  • the drive circuit board 12 may be lengthways mounted into the thru hole 111 of heat dissipation part 11, and a power cord 121 is provided at an upper side and an insertion slot 122 is formed at a lower side.
  • the LED lamp board 13 is arranged transversally on a side below the heat dissipation part 11 and comprises a substrate 131.
  • the LED lamp board 13 on the top side of substrate 131 is provided with a plug 132 to connect to the insertion slot 122 of drive circuit board 12.
  • a plurality of LEDs 133 are provided on the bottom side of substrate 131 of the LED lamp board 13.
  • the lamp cover 20 is arranged below the LED lamp board 13 and is formed into a mouth facing upwards; it is a round cover formed with an annulus wall and allows light transmission; a shoulder region 21 is formed around the outer circumference of root edge of the cover 20. Further, an optics curved surface 22 is formed at the bottom side of lamp cover 20 so that the cover 20 may be replaced with a proper lamp cover 20 having the optics curved surface 22 upon an actual demand.
  • the insulation cover 30 may wrap around the heat dissipation part 11 for fear of touch with the metallic heat dissipation part 11.
  • the insulation cover 30 is further assembled with an upper insulation cover 31 and a lower insulation cover 32.
  • the upper insulation cover 31 is in the form of a cylinder and wraps around the heat dissipation part 11 from top to bottom. Further, the circumferential wall of upper insulation cover 31 is formed in the shape of grille with a plurality of heat dissipation vent 311. A plurality of annular flanges 312 opposite to the annular grooves 113 of heat dissipation part 11 are formed at the inner wall of upper insulation cover 311 and may wedge to each other for clamping. A top plate 313 is transversally arranged at the top of insulation cover 311 that is opposite to the top side of heat dissipation part 11 to prevent the top side of heat dissipation part 11 from being exposed for achievement of insulation.
  • An outgoing line hole 314 is formed on the top plate 313 the bottom side of which is formed with a plurality of lugs 315 to bring a plurality of air gaps between the top plate 313 and the top of heat dissipation 11 for heat dissipation.
  • the lower insulation cover 32 is also in the form of a cylinder and wraps around the lower section of heat dissipation part 11 from bottom to top.
  • the circumferential wall of lower insulation cover 32 is also formed in the shape of grille with a plurality of heat dissipation vents 321.
  • a plurality of annular flanges 32 opposite to the annular grooves 113 of heat dissipation part 11 are formed at the inner wall of lower insulation cover 322 and may wedge to each other for clamping.
  • a convex shift limit flange 323 is provided at the shoulder region 21 of lamp cover 20 that is opposite to the root edge of inner circumferential wall of the lower insulation cover 32 to prevent the lamp cover 20 from shifting.
  • an outer disk cover 33 spirally removable and replaceable is provided outwards and transversally in the insulation cover 30 around the outer circumference of the lower part of lower insulation cover 32.
  • an elastic clamping flake 34 is provided at each of opposite two sides of the insulation cover 30 around the outer circumferential wall of lower insulation cover 32 above the outer disk cover 33.
  • the elastic clamping flake 34 may be removable and may recover even if being deformed with an external force.
  • a space substantially equal to the thickness of ceiling is formed between the elastic clamping flake 34 and the outer disk cover 33.
  • Each of the elastic clamping flakes 34 is a metallic elastic flake one end of which is a fixed end fixed in the direction of tangent onto the lower insulation cover 32 and the other end of which is a free end, and the bottom of each of the elastic clamping flakes 34 is convergent from the fixed end towards the free end.
  • the extension cover 40 is formed into a mouth facing downwards and with a round cover having an annular wall, and may be wedged onto the top of upper insulation cover 31.
