Modularized LED street lamp

The invention discloses a modularized LED street lamp. The modularized LED street lamp consists of a radiation module, an LED light source module, a drive power supply module and a protection module, and has the advantages that: the modularized LED street lamp is assembled in a modularized mode; and all modules are mutually independent as well as closely combined. In the process of mounting the street lamp, the modularized structure can not only greatly improve production efficiency, but also make assembly and production of lamps in different places more convenient; and in the process of maintenance, the damaged parts can be changed by replacing a module rather than disassembling the whole lamp head of the LED street lamp.
