Abstract

A waterproof power module of light-emitting diode (LED) road lamp comprises a cover body, a base, a circuit board provided with a power supply drive circuit and a ventilation valve. The circuit board is contained in a sealed space formed by the cover body and the base. The ventilation valve is arranged on the cover body so that hot air in the base and outside air can be subjected to heat exchanging through the ventilation valve. The ventilation valve replaces a ventilation through hole of an existing power supply module for heat exchanging, due to the fact that a ventilation window of the ventilation valve is placed on the side wall of a valve body, the problem that rain water directly permeates in can be avoided, a ventilation film is covered on a ventilation channel of the valve body, and insects or other impurities can be filtered so that the insects or the other impurities cannot enter the base. The waterproof power module is good in waterproof effect, and accordingly the service life of the LED road lamp can be prolonged.
