PURPOSE: An aluminum alloy streetlamp post is provided to cut down on installation and maintenance cost by employing aluminum rather than iron or stainless steel and to improve the structure stability by reinforcing an opening for stabilizer installation. CONSTITUTION: An aluminum alloy streetlamp post comprises a lower lamp post(10), a reinforcing pipe(20) for reinforcing an opening of the lower lamp post which is cut for installation of a stabilizer, an upper lamp post(30), a lamp post connecting pipe(40) which connects the upper and lower lamp posts, an arm fixing pipe(60) connected on the top of the upper lamp post, an arm connecting pipe(70) which connects the upper lamp post and the arm fixing pipe, and first and second rainproof covers(50,80) for preventing the infiltration of rainwater into the junction of the upper and lower lamp posts and into the junction of the upper lamp post and the arm fixing pipe.
