The invention discloses a wind-inlet-volume-adaptive-adjustment wind energy LED lighting street lamp. The wind-inlet-volume-adaptive-adjustment wind energy LED lighting street lamp structurally comprises a wind-volume adaptive device, a wind power generation device, lighting lamps, lamp stands, a wind direction trace device, a vertical column and a base, wherein the base is perpendicularly connected to the bottom of the vertical column; compared with the prior art, the wind-inlet-volume-adaptive-adjustment wind energy LED lighting street lamp has the advantages that the wind-volume adaptive device is additionally arranged on the wind energy street lamp, and by combining a protection cover, wind-volume self-adjusting mechanisms and spring groups, the lamp can self-adapt to the wind speed; when wind power is small, a wind inlet can be enlarged, and contains much wind, and power generation of a wind energy power generator is facilitated; when the wind power is large, the wind speed is detected by a wind speed sensor and is delivered to the wind-volume self-adjusting mechanisms to self-adjust the size of the wind inlet, the wind inlet volume and the wind inlet speed are decreased accordingly, and it is effectively avoided that as wind power is over large, the wind power generation device is damaged.
