The invention discloses a street lamp convenient to replace. The street lamp convenient to replace comprises a lamp pole and a lamp holder. The bottom of the lamp holder is provided with a base. The lamp holder is provided with an LED. A lifting device used for increasing and decreasing the height of the lamp holder is arranged in the lamp pole. The lifting device comprises a locating plate arranged on the top of the lamp pole. The locating plate is provided with pulleys and fixing blocks coaxially connected with the pulleys. The fixing blocks are connected with the locating plate. The lifting device further comprises a first directional wheel, a second directional wheel and a third directional wheel, wherein the first directional wheel is arranged on the top of the lamp pole, the second directional wheel is arranged in the middle of the lamp pole, and the third directional wheel is arranged at the bottom of the lamp pole. The lifting device further comprises a lifting rope. When a user needs to replace the LED, the third directional wheel is rotated, so that the length of the lifting rope wound around the third directional wheel is reduced, the height of the lamp holder is reduced, and the LED is convenient to replace; and after replacement is completed, the third directional wheel is rotated again, so that the length of the lifting rope wound around the third directional wheel is changed, and then the height of the lamp holder is increased.
