The present invention relates to a parabolic reflector (PAR)-type LED lighting apparatus based on an LED. A COB-type LED module having a multi-chip array structure, a heat sink, an optical system for a backlight control, and an SMPS embedded in the heat sink are integrally formed in an assembled structure. Thus, it is possible to replace a conventional PAR-type halogen lamp or a conventional PAR-type LED lamp, to implement various backlight patterns, to easily perform backlight control for light emitted from the LED module, to remove a yellow pattern or a spot caused by forming a cross wave pattern portion in an LED lighting that is a substitute for a conventionally proposed PAR-type LED lamp, thereby realizing high efficiency, high heat dissipation, and excellent light uniformity and reducing manufacturing costs. The LED module and the SMPS, which are components having electric characteristics, can be independently replaced. Therefore, when a problem occurs, the problme can be solved by simply replacing parts. A user can directly replace parts with ease, thereby facilitating post management and maintenance. |
