LED light and method of manufacturing the same

摘要

Provided is an LED light that includes a base plate, heat pipes disposed on the base plate, at least one heat dissipation fins disposed on the heat pipes, and an LED module fastened to the base plate by screws, in which protrusions having a space with the bottom open integrally protrude from the base plate and a thread for thread-fastening of the screw is formed around the inner side of the protrusions. Accordingly, water or foreign substances from cannot flow into the LED module through around the screw, with high waterproof ability.
