High-power light-emitting diode (LED) road lamp

A high-power light-emitting diode (LED) road lamp comprises a lamp casing of the road lamp, an aluminum radiator is arranged in the lamp casing, and at least one LED chip assembly is fixed at the bottom of the aluminum radiator through heat conducting glue. A cold air flow guiding pipe is arranged in the lamp casing, one end of the air flow guiding pipe is connected with a metal hollow pipe communicated with the outside through a transition pipe, and an air outlet pipe port at the other end of the air flow guiding pipe is inserted into the middle of the aluminum radiator in inclined mode and faces the bottom portion of the aluminum radiator adhered with the LED chip assembly in inclined mode. The aluminum radiator is composed of an aluminum base and a radiating fin. A thermal radiation cooling material is coated on the surface of the radiating fin. A radiating hole perpendicular to the aluminum base is arranged on the aluminum radiator along the direction of the radiating fin. The air outlet pipe port is inse
