The present invention relates to an LED lighting device and, more specifically, to an LED lighting device comprising: an LED lamp; a lampshade which holds the LED lamp and has multiple through-holes on the top in order to enable the heat released from the LED lamp to flow upward; a power supply unit which is arranged on top of the lampshade and supplies power to the LED lamp at a constant level; a heat collection unit which is arranged on top of the lampshade to be superposed onto the multiple through-holes, collects heat generated by the LED lamp and the power supply unit, and has a heat-discharging hole on the top surface to discharge the collected heat; and a heat-discharging pipe whose one end is connected with the ceiling or the outside and the other end has a variable length in order to be connected with the heat-discharging hole. The LED lighting device according to an embodiment of the present invention can be cooled down by discharging the heat of the LED lamp and power supply unit to the outside, and if needed, enables the heat of the LED lamp and power supply unit to be used for heating. |
