PURPOSE: An LED streetlight is provided to reduce maintenance and maintenance costs by repairing only damaged light emitting module. CONSTITUTION: A case(20) is prepared in a pillar(10). A first substrate is installed in the case and supplies power to the case. A plurality of light-emitting diode modules(40) are attached to the first substrate. The light-emitting diode modules comprise an LEDs light-emitted according to the power provided from the first substrate. The light-emitting diode modules comprises a reflector controlling the illumination range of the LED light and a cooling fin releasing the heat from the LEDs. The LEDs has luminance according to light-emitting diode modules.
