Zusammenfassung:	The utility model relates to a high-power LED lamp bulb which comprises a lamp body, a base and a lamp cap, wherein an LED lamp is installed in the base. A radiating shell taking the shape of a round platform is arranged outside the base, the upper bottom of the round platform is fixedly connected with the base, and the lower bottom of the round platform is fixedly connected with the lamp body. The LED lamp in the base adopts an ACLED (alternating current LED) or a DCLED (direct current LED) as a light source; a groove is arranged on the side face of the round platform, and the cross section pattern of the groove is in a same plane and is formed by a plurality of line segments and curved sections, or the line segments and the curved sections are connected in sequence from beginning to end but do not intersect with each other. The high-power LED lamp bulb increases the radiating area of the lamp and effectively improves the radiating efficiency of the lamp. When the ACLED (alternating current LED) is adopted,
