Abstract: 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.

Abstract: Provided is an LED light which may include a base plate, an LED module disposed under the base plate, a plurality of heat pipes provided over the base plate, and a plurality of heat dissipation fins provided over the base plate. The plurality of heat pipes may include a first portion thermally coupled to the base plate and a second portion that extends from the first portion. The plurality of heat dissipation fins may be spaced apart from each other and thermally coupled to the second portion of the heat pipes to dissipate heat from the LED module. The LED light may include an upper bracket provided over the plurality of heat dissipation fins and fastened to a hanger, and a plurality of studs that connect the base plate to the upper bracket.
