DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 3The utility model provides a technical solution: a lighting street lamp, comprising a rod body 1, a cavity 101 opened at the top of the rod body 1, the cavity 101 is connected to the outside of the rod body 1, a motor 2 is fixedly installed on the top of the rod body 1, the output end of the motor 2 passes through the cavity 101 and is fixedly connected to a screw rod 3, the other end of the screw rod 3 is rotatably inserted in the bottom wall of the cavity 101, a guide rod 4 is fixedly connected between the top wall and the bottom wall of the cavity 101, a connecting strip 5 is threadedly sleeved on the screw rod 3, the guide rod 4 movably passes through the connecting strip 5, both ends of the connecting strip 5 are respectively fixedly connected to connecting plates 6, and a lamp body 7 is fixedly installed at the end of the connecting plate 6.

[0022] By starting the motor 2, the screw rod 3 is driven to rotate, the screw rod 3 drives the connecting bar 5 to descend, and the connecting bar 5 drives the connecting plates 6 at both ends to descend, so that the lamp body 7 is lowered, which is convenient for maintenance or replacement of the lamp body 7.
