Abstract

The utility model relates to an LED street lamp with balanced load bearing. The LED street lamp adopts the structure that a radiator is arranged on the back surface of a lamp holder body and includes radiating fins on both sides and structural grooves in the middle; end covers are arranged at the upper and the lower ends of the radiator respectively; a concave fixing frame is fixedly mounted in the middle of the structural grooves of the radiator; and a sleeve is clamped on the inner side of the concave fixing frame. The utility model has the advantages that the combined structure of the concave fixing frame and the sleeve is arranged in the middle of the structural grooves, so as to effectively balance the load-bearing pressure of a lamp holder of the LED street lamp; the sleeve is clamped on the inner side of the concave fixing frame, so that with the bearing capacity unchanged, two clamping seat type wings of the original sleeve is no more needed, and the manufacturing cost is further reduced; and as the distance between the sleeve and the lamp holder of the LED street lamp is smaller, the load-bearing capacity of the sleeve is enhanced.
