The present invention relates to an LED lighting device. The LED lighting device comprises: a first cover including a ventilation hole; a thermal base including one side having an opening and the other side coupled to the first cover, wherein the thermal base has an air flow passage connecting the ventilation hole to the opening therein to guide the flow of air introduced into the air flow passage; an LED package disposed outside the thermal base for dissipating heat through the air flowing into the air flow passage; an electrical connection part coupled to the first cover and electrically connected to the LED package; and a second cover covering the LED package to protect the LED package. The thermal base has a reflective surface which reflects at least a portion of the light emitted from the LED package so as to diffuse the light. |
