1. A lighting apparatus comprising:
one or more light-emitting diode (LED) modules; a base plate having a bottom surface to which the one or more light-emitting diode modules are attached; and a heat dissipation fin assembly including a plurality of heat dissipation fins, the heat dissipation fin assembly being seated on a top surface of the base plate and formed by a thin sheet of a graphite material; wherein the heat dissipation fin assembly has a structure in which a sheet of heat dissipation fin plate is bent several times in a zigzag shape to have a plurality of bent parts, and is disposed in a circumferential direction on the top surface of the base plate, wherein the heat dissipation fin assembly is defined as an assembly of a plurality of fin parts which are partitioned by the plurality of bent parts, wherein the plurality of bent parts comprise:
a plurality of inner bent parts disposed inside the base plate; anda plurality of outer bent parts disposed on an outer edge of the base plate and alternately disposed with the plurality of inner bent parts in the circumferential direction of the base plate, and wherein the heat dissipation fin assembly has:
an inner air-vent hole defined by cutting at least a portion of each of the plurality of inner bent parts; andan outer air-vent hole defined by cutting at least a portion of each of the plurality of outer bent parts.
