The present invention relates to an LED streetlamp having a radiator. An LED streetlamp (100) includes an LED panel (20) at which multiple LEDs (10) are fixed; and a radiator (50) for fixing the LED panel. The radiator (50) is composed of an LED panel accommodation unit (55) accommodating the LED panel (20) in the front thereof and being covered with a transparent glass (40); and a radiation chamber (80) having multiple wrinkle portions (85) and disposed at the rear of the LED panel accommodation unit, wherein the radiation chamber is filled with antifreeze as cooling water, whereby heat dissipation of the LEDs is accelerated by rise of the radiation chamber and the cooling water when the LED streetlamp is turned on, and also it is possible to prevent the radiation chamber from being destroyed due to expansion upon freezing when the LED streetlamp is not on. |
