A lighting apparatus receives a regulated AC line voltage as an input voltage and comprises a light emitting diode array and a driving circuit. The light emitting diode array is composed of at least one light emitting diode set connected in parallel. The driving circuit has a plurality of outputs corresponding to the light emitting diode sets, and each output has a predetermined value for controlling the brightness of the light emitting diode set. Each light emitting diode set is conducted automatically and in sequence for a fixed time interval based on the output of the driving circuit and the amplitude of the regulated AC line voltage, and is turned off based on the predetermined signal of the driving circuit.
