LED street lamp with good heat dissipation effect

The invention relates to an LED street lamp with a good heat dissipation effect. The LED street lamp comprises a base, a supporting rod, a cross rod and a main body, wherein the main body comprises ashell, a fixing plate, a main plate, an LED lamp strip, a driving assembly, a heat dissipation assembly and a water cooling assembly; and the driving assembly, the heat dissipation assembly and the water cooling assembly are all arranged in the shell. According to the LED street lamp with the good heat dissipation effect, heat generated by the LED lamp strip is absorbed through the heat dissipation assembly, so that heat dissipation is realized; the driving assembly is driven by wind power to realize wind power heat dissipation, and the water cooling assembly is driven by the driving assemblyto operate, so that water cooling heat dissipation is realized; compared with an existing street lamp, the street lamp has the advantages that a better heat dissipation effect is achieved through multiple heat dissipation; the
