A heat dissipation structure of an LED lamp is provided to improve power supply efficiency by converting an AC into a DC through an LED power circuit. A heat dissipation structure of an LED lamp(100) includes a heat dissipation frame(120) and an LED module(110). A heat dissipation hole is formed in the heat dissipation frame. The heat dissipation hole cools the LED module by using convection of an air. The heat dissipation frame includes a first heat dissipation part and a second heat dissipation part. The LED module is mounted on the first heat dissipation part. The first heat dissipation part includes a body, a first heat dissipation fin, and a heat dissipation groove. The first heat dissipation fin is protruded from a top surface of the body to a top side. The second heat dissipation part is protruded from a side surface of the first heat dissipation part. The second heat dissipation part includes a second heat dissipation fin. The second heat dissipation fin is vertically formed in both ends of the body. |
