An LED street lamp capable of adjusting the number of LED modules to be provided comprises: an LED module unit including a heat dissipation structure, configured to adjust the number of LED modules to be provided according to required brightness, and including first to five LED modules and a module installation plate for installing the LED modules; an outer container unit forming the appearance, coupled to a street lamp post, having the LED module unit arranged on the bottom surface, and having an upper surface with a structure capable of easily dissipating heat; and a converter provided in the outer container unit, and configured to obtain a direct current output voltage using a switching circuit and supply power to the LED modules. The outer container unit comprises: an outer container unit body coupled to the street lamp post, configured to receive power, and having the converter provided therein; a lower cover having one end coupled thereto to be rotated at a predetermined angle such that the lower cover can be opened and closed as necessary, and having the LED module unit provided therein; and an upper cover configured to form a cover for covering the upper part of the outer container unit and an internal space, and to dissipate heat generated by the LED module unit. The LED street lamp capable of adjusting the number of LED modules to be provided adjusts the number of LED modules to be provided according to required brightness, thereby reducing the number of parts required for the LED street lamp, and lowering production costs. The LED street lamp has a structure capable of easily dissipating heat, thereby improving the durability of the LEDs. |
