Abstract: A high-power light emitting diode (LED) street lamp includes a body frame, a plurality of light emitting diode (LED) modules, and a base unit convexly positioned on the body frame along the light emission direction of the high-power light emitting diode (LED) street lamp. The light emitting diode (LED) modules have a plurality of light emitting diodes (LEDs), and at least one circuit board. The light emitting diodes (LEDs) are electrically connected to the at lease one circuit board. The base unit has a plurality of supporting surfaces which support the light emitting diode (LED) modules. The supporting surfaces are symmetrically positioned on a normal direction of an end surface of the base unit, and the light emitting diode (LED) modules are positioned on the adjacent supporting surfaces, respectively. The supporting surfaces further comprise a plurality of edge supporting surfaces positioned on the edges of the base unit.
