The invention discloses an easy-heat-dissipation self-cleaning good-weatherability LED streetlamp pole comprising a lampshade, a lamp pole body and an electrifying connector. An electric wire is connected with the lamp pole body, and the lampshade is connected with one side of the top end of the lamp pole body. A fixed rod is connected in the lampshade and is connected with a lamp tube. A bulb is arranged in the lamp tube. A screw is connected to the front segment of the lamp tube and penetrates through heat-dissipation silicone grease. A heat-dissipation plate is arranged in the heat-dissipation silicone grease and is connected with the middle segment of the lamp tube. The middle segment of the lamp tube is connected with the rear segment of the lamp tube. One side of the bottom end of the lamp pole body is provided with the electrifying connector, and a turning cover is arranged on the surface of the electrifying connector. According to an LED streetlamp, heat dissipation of elements in the streetlamp is achieved very well, lumen depreciation is controlled effectively, service life of the streetlamp is protected, meanwhile, the functions of the lamp pole are enriched, an electrombile and small-power electronic equipment can be charged, convenience is brought to traveling of people, and the design is worthy of use and popularization.
