A high power LED lamp includes a housing (19), a lighting assembly and heat-dissipating fins (10). The lighting assembly includes a reflective cup (15a), a LED (13) and a lens (15). The heat-dissipating fins (10) are arranged in the channel of the housing (19) in a radiation shape. The outer end of each heat-dissipating fin (10) contacts with the inner wall of the housing (19), and the inner end thereof connects with the outer wall of a ring-shape barrel (9). The front ends of all the heat-dissipating fins (10) form a ring surface with a concave cone shape. The reflective cup (15a) is arranged at the ring surface. The axis of the ring-shape barrel (9) coincides with the axis of the housing (19). The front end face of the ring-shape barrel (9) forms a plane shape, and the LED (13) and the lens (15) are arranged on the plane face. |
