The invention relates to the technical field of illumination, and discloses an LED street lamp convenient to maintain. The LED street lamp comprises a concrete block. An arc clamp groove is formed in the middle of the upper surface of the concrete block. The upper surface of the arc clamp groove is fixedly connected with an alloy piece. The upper surface of the alloy piece is fixedly connected with fixed bolts. A lamp pole is fixedly connected in the arc clamp groove through the alloy piece. The front face of the lamp pole is fixedly connected with a rotary shaft. The surface of the rotary shaft is fixedly connected with steel bars. A magnet is adsorbed to the end of each steel bar. The surface of the lamp pole is movably connected with a moving rod. The front face of the moving rod is fixedly connected with a handle. According to the LED street lamp convenient to maintain, the lamp pole of the street lamp is fixedly connected with the moving rod and the handle, through the process of arranging a hydraulic pump to drive a hydraulic cylinder to push a hydraulic rod, people can conveniently maintain a lamp bulb effectively, and street lamp bulb replacement can be achieved conveniently and fast; and the good working stability and safety are achieved, and the effects of convenient maintenance and convenient lamp replacement are achieved.
