Zusammenfassung:	PURPOSE: A bulb-type LED lighting device is provided to remove a central core structure of an existing LED lighting device by making a passage for wiring at a random heat dissipation fin included in a heat sink, thereby facilitating reduction in weight and performance improvement in heat dissipation of an LED lighting device. CONSTITUTION: An LED lighting device (1) comprises a heat sink (10) including a plurality of heat dissipation fins; a light emitting module (20) disposed on the top of the heat sink; a power connection unit (30) disposed under the heat sink; a transparent cover (40) installed to cover the top of the light emitting module; and a wiring passage (142) formed at a random heat dissipation fin of the plurality of the heat dissipation fins for accommodating wirings to electrically connect the power connection unit and the light emitting module, and is characterized by comprising an empty space in the inner side of the inner edges of the plurality of heat dissipation fins.
