Abstract:
An alternating current (AC) light emitting device includes an AC light emitting diode (LED) module and a waveform modulation unit. The AC LED module includes at least two sets of micro-diodes. The waveform modulation unit coupled between the AC LED module and an AC voltage source modulates a waveform of the AC voltage source.
