Disclosed are an LED lighting device and a streetlight device having the same. The LED lighting device includes:an LED module; a thermal base coupled with the LED module and configured to absorb heat; and a heat-pipe loop formed in a tubule shape and having working fluid injected thereinto and comprising a heat-absorption portion coupled with the thermal base and configured to absorb heat and a heat-dissipating portion configured to dissipate the heat absorbed by the heat-absorption portion, wherein each coil of the heat-pipe loop is formed in a thin and long shape, and one side of the thin-and-long coil is coupled to the thermal base, and the other side of the thin-and-long coil is protruded to an outside from an edge of the thermal base.The LED lighting device can be formed into a thin shape despite a wide heat-dissipation area and high heat-dissipation performance, and thus can be installed with little limitations and readily stored and transported.Moreover, since a good air ventilation effect can be realized using air flow, the heat-dissipation performance can be maximized. |
