Abstract: Disclosed is a light-emitting diode (LED) lighting apparatus having a multifunctional heat sink flange, which includes an LED board on which a transmitted light cap and a plurality of LEDs are mounted, a main heat sink formed of magnesium or an magnesium alloy, an auxiliary heat sink formed of a conductive/polymeric resin material for heat dissipation, a heat sink upper case formed of a conductive/polymeric resin material for heat dissipation, and a power supply. The main heat sink includes multiple streamlined heat sink segments that are integrally formed on an outer surface thereof so as to radially protrude to allow air to flow in all directions, and a heat sink flange formed along an outer circumference of a bottom thereof such that omega-shaped wings having enclosed holes and inverse omega-shaped open holes are alternately formed.

Abstract: Disclosed herein is an LED-type illuminating module, which independently functions as an illuminating apparatus and which is used to constitute various kinds of illuminating apparatuses having desired outputs by providing a plurality of the LED-type illuminating modules on a module fixing plate 8 of a predetermined area, including: a light transmission or diffusion plate; an LED substrate on which LEDs are fixed at regular intervals by soldering; a radiator formed by die-casting a light metal alloy; a waterproof ring; a plurality of radiating plates made of a light metal alloy; a housing formed by injection-molding a conductive polymer resin material; a waterproof packing; and a power supply converter.
