LED LIGHTING DEVICE WITH STRUCTURE OF HEAT SINK HAVING HIGH HEAT DISSPATION

摘要

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 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) surrounds the outside of the light-emitting direction of the LED device. The main heat radiation unit includes a plurality of heat radiation pins(P2). The plurality of heat radiation pins are formed among protruded wave patterns on the outer surface.
