The present invention relates to a prefabricated street lamp pole having vibration absorption and rotation prevention functions. A shock absorbing ring formed of silicon or rubber is inserted into an connection end between an upper pole and a lower pole to offset or prevent vibration of the upper and lower poles by absorbing shock. When the prefabricated street lamp pole is installed on a bridge or a road including an industrial road on which heavy vehicles frequently run, the prefabricated street lamp pole can prevent a post pole from being rotated and can prevent a screw coupling member (a bolt and a nut) of each assembly unit from being easily released. If a lamp assembly unit is formed in a screw lamp method, the prefabricated street lamp pole prevents the lamp assembly unit from being released. If the prefabricated street lamp pole is applied to an LED lamp, the prefabricated street lamp pole prevents the assembly of an SMPS and a PCB board inside the lamp from being released. The prefabricated street lamp pole also has an extended life by preventing a contact failure in advance and is fundamentally prevented from being distorted in entire parts. The prefabricated street lamp pole can obtain structural stability and can improve productivity by enabling a worker to conveniently conduct construction. |
