The present disclosure relates to an LED lighting device. The LED lighting device includescomprises: a power supply partunit housing on in which a power supply partunit is mounted; a lighting partunit housing receiving a board on which LEDs are mounted; and a connection partunit connecting the said power supply partunit housing to the said lighting partunit housing so that a heat conduction preventing partunit providing a space in which air is convected is disposed between the said power supply partunit housing and the said lighting partunit housing. According to the present disclosure, at least the connection partunit is disposed between the LED lighting partunit and the power supply partunit, and the LED lighting partunit and the power supply partunit are spaced apart from each other except for at the connection partunit. Thus, heat generated in the LED lighting partunit is conducted into the power supply partunit, or heat of in the power supply partunit is prevented from being conducted into the LED lighting partunit to prevent the life cycle of the LED lighting partunit or the power supply partunit from being reduced. |
