Abstract: Disclosed is an LED lighting apparatus having a natural convection-type heat dissipation structure. The LED lighting apparatus includes a heat sink coupled to a back surface of a printed circuit board (PCB) to which a plurality of light emitting diode (LED) devices is mounted and, and functioning to absorb heat generated by the LED devices, in which center portions of the heat sink and the PCB are provided with openings serving as a convection hole that induces natural convection such that hot air under the heat sink rises along with rising hot air attributed to heat radiated from an upper surface of the heat sink and surrounding cooler air is supplied to the upper surface the heat sink and to around the LED devices. Due to the convection hole, the LED lighting apparatus provides a heat dissipation effect as high as that of an active cooling system.
