The present invention relates to an LED lighting apparatus which includes a socket part (100) and an LED installed light emitting part (300) which is combined with the socket part (100). The socket part (100) and the light emitting part (300) are separable. A power supply part (200) is selectively installed between them, and by selectively detaching the power supply part, the LED lightning apparatus can be conveniently formed to have either a high power or low power consumption as necessary.
