PURPOSE: A heat radiating body for an LED lighting apparatus is provided to improve heat dissipation efficiency by airflow through an air flow hole. CONSTITUTION: A heat radiating body(10) includes a plurality of heat radiation fins(12). An LED module is mounted on the top or the bottom of a main body(11). A plurality of air flow holes(13) is punched on the main body. The air flow hole is formed to be completely passed through from one side to the other side of the main body. A plurality of convection induction grooves(14) is spirally formed in the inner circumference of the air flow hole. |
