1. A rectangular light emitting diode (LED) lighting apparatus, comprising:

  • a printed circuit board in which circuit patterns are formed for electrical connection of LEDs;

    a rectification unit configured to rectify an alternating current (AC) voltage and output a direct current (DC) rectified voltage;

    an LED unit driven by the rectified voltage, the LED unit including first to n-th light emitting blocks, where n is a positive integer equal to or greater than 2, the first to n-th light emitting blocks arranged linearly on the printed circuit board; and

    an LED driving control unit configured to sequentially drive first to m-th light emitting groups, where m is a positive integer equal to or greater than 2, each of which includes n LEDs, according to a voltage level of the rectified voltage output from the rectification unit,wherein each of the first to n-th light emitting blocks includes first to m-th LEDs arranged linearly, and each of the first to m-th LEDs is sequentially turned on and off according to the voltage level of the rectified voltage.
