PROBLEM TO BE SOLVED: To provide an AC LED lighting apparatus capable of compensating for a delay caused by signal processing.SOLUTION: The AC LED lighting apparatus includes: a rectification unit configured to rectify and convert an AC voltage, and output a DC rectified voltage; an LED light-emitting unit including a first light emitting group to an n-th light emitting group (n is a positive integer equal to 2 or greater) each including at least one LED; and an LED driving control unit configured to control driving of the first light emitting group to the n-th light emitting group by comparing a voltage level of the rectified voltage inputted from the rectification unit with a reference voltage and controlling at least one switch. The LED driving control unit calculates reference voltage adjustment values with which a delay caused by signal processing in the LED driving control unit can be compensated for, and the calculated reference voltage adjustment values are substantially identical to each other. |
