PURPOSE: An LED lighting device having a heat radiation performance maximization heatsink structure is provided to improve effect of heat radiation by maximizing contact area with air by arranging the maximum number of multiple curved shape heat radiation pins and heat spreading holes in the minimum space. CONSTITUTION: An LED device is formed in an LED lighting main body(10). The LED device is connected with a PCB substrate. A main heat radiation unit(30) is extended to surround the outside of the light-emitting direction of the LED device. A plurality of heat radiation pins(P2) have at least one different radius of curvature. The plurality of heat radiation pins are formed in the main heat radiation unit. |
