Disclosed is an LED lighting device. The LED lighting device comprises: an LED module; a thermal base coupled to the LED module to absorb heat; a heat chamber having a sealed internal space into which a working fluid is injected; a heat absorption unit which is combined with the thermal base to absorb heat and is provided on the inside wall thereof with a wick; and a heat radiation unit in which the working fluid evaporated in the heat absorption unit is condensed to radiate heat. The LED lighting device is resistant to contamination and allows contamination to be easily removed therefrom, and thus the degradation of a heat radiation performance is minimized and maintenance becomes easy. In addition, the LED lighting device radiates heat from the LED module while preventing heat from the sun from being transferred thereto, and thus the LED lighting device is prevented from being heated by solar heat. |
