The LED street lamp according to claim 1, wherein the LED street lamp comprises an elastic latch for connecting the upper housing and the lower housing, the elastic latch comprises a lock bar disposed on any one of the upper housing and the lower housing and a latch body disposed on the other one of the upper housing and the lower housing, the latch body comprises a support frame for mounting the latch body, a rotating wheel rotatably disposed on the support frame and an elastic member disposed between the support frame and the rotating wheel, one end of the elastic member is connected with the top end of the rotating wheel, the other end of the elastic member is connected with an area of the support frame below the rotating wheel, a slot matched with the lock bar is disposed on the edge of the rotating wheel, and a limit mechanism is disposed between the support frame and the rotating wheel, when the elastic lock catch is in an unlocking state, the lock rod is separated from the clamping groove, the elastic piece pulls the rotating wheel to deflect through the elastic force of the elastic piece, so that the axis of the elastic piece and the axial direction of the support frame deviate, and the rotating wheel is kept to deflect relative to the support frame through the limiting action of the limiting mechanism; the locking rod is clamped in the clamping groove by applying force to the locking rod, the force drives the rotating wheel to deflect reversely, the axial line of the elastic part and the axial direction of the supporting frame deflect reversely, and the rotating wheel is kept to deflect reversely relative to the supporting frame by the limiting function of the limiting mechanism.

6. The LED street lamp according to claim 5, wherein the limiting mechanism comprises a sliding groove arranged on the rotating wheel and a limiting rod arranged in the sliding groove, and the limiting rod passes through the sliding groove and abuts against the supporting frame to limit the rotation of the rotating wheel relative to the supporting frame.

7. The LED street lamp according to claim 1, wherein the LED street lamp comprises a hinge mechanism configured to detachably hinge the upper and lower housings, the hinge mechanism comprises a fixing shaft disposed on either one of the upper and lower housings and a shaft hole disposed on the other one of the upper and lower housings, the fixing shaft is matched with the shaft hole, and the hinge mechanism comprises a position-limiting piece disposed on either one of the upper and lower housings and a position-limiting groove disposed on the other one of the upper and lower housings, an end of the position-limiting groove is provided with a protrusion configured to contact the position-limiting piece when a relative angle between the upper and lower housings is 45-60 degrees so as to rotate beyond the relative angle, the limiting groove is separated from the limiting sheet.

8. The LED street lamp according to claim 7, wherein a stopper is disposed at one end of the fixing shaft, so that the fixing shaft can be detached from the shaft hole by moving in a direction of one side of the fixing shaft, thereby facilitating disassembly.

9. The LED street lamp according to claim 1, wherein the LED street lamp comprises a safety lock for connecting the upper housing and the lower housing, the safety lock comprises a lock hole arranged in any one of the upper housing and the lower housing and a lock block rotatably arranged in the other one of the upper housing and the lower housing, when the safety lock is in an unlocked state, the lock block is separated from the lock hole and is positioned on one side of the lock hole; the locking block is moved from one side of the lock hole to the other side of the lock hole by applying force, and is rotated to enable the locking block to abut against the main body around the other side of the lock hole, so that the locking block is combined with the lock hole.

10. The LED street lamp according to claim 1, wherein the safety lock comprises a plurality of pairs of rotation limiting mechanisms, each rotation limiting mechanism comprises an elastic protrusion and a concave part matched with the elastic protrusion, the rotation limiting mechanism is arranged between the other side of the lock hole and the lock block, and the rotation limiting mechanism is arranged between the lock block and a housing on which the lock block is mounted.
