High-power LED lamp

The invention provides a high-power LED lamp. The high-power LED lamp comprises a hollow polyhedral cone with an upper bottom surface and a lower bottom surface, wherein oblique surfaces of the polyhedral cone are set as LED mounting surfaces, LED lamps are mounted in the centers of the oblique surfaces, and a plurality of radiators are arranged on the periphery of the LED lamps; the two bottom surfaces of the polyhedral cone are the upper mounting surface and the lower mounting surface respectively, and mounting holes are formed in corners of the upper mounting surface and the lower mounting surface. The high-power LED lamp adopt the hollow polyhedral cone and can emit light at the angle of 240 degrees, and two hollow polyhedral cones can be in butt joint, so that 360-degree omnidirectional light emitting is realized; a casing is not added, a plurality of radiating through holes are formed in the hollow polyhedral cone, and the radiating effect is good; the problems about the light emitting angle and radiating are solved, the high-power LED lamp is simple and convenient to mount and maintain, other light sources provided with screws in existing lamps can be conveniently replaced, and the universality is high.
