LIGHT-EMITTING DIODE LIGHTING APPARATUS HAVING MULTIFUNCTIONAL HEAT SINK FLANGE

摘要

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.

1. A light-emitting diode (LED) lighting apparatus having a multifunctional heat sink flange comprising:
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, wherein 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, whereby the LED lighting apparatus functions as a low-powered lamp when installed independently, and is used for other high-powered lamps when combined and installed in a case having a predetermined area and shape so as to have desired light output.
