An LED(Light Emitting Diode) street light is provided to satisfy a light distribution regulation by forming a PCB(Printed Circuit Board) mounting surface of a lamp mount according to an installation environment. An LED lamp module includes a lamp mount(20), an LED(11), and a PCB(13). The lamp mount is detachably coupled in a housing(30). An LED is mounted on the PCB. The lamp mount has at least two PCB mounting surfaces or more. A heat discharging unit is formed in the rear of the PCB mounting surface. The housing includes at least one module installing unit(31) and a heat absorbing connection part(33). An LED lamp module is installed in the module installation unit. The heat absorbing connection unit corresponds to the heat discharging connection unit of the lamp mount. |
