Abstract
Embodiments of the invention provide AC LED lighting apparatuses. The AC LED lighting apparatuses may increase luminous flux and provide optimal efficiency through novel arrangement of a plurality of light emitting blocks on a circuit board and a plurality of LEDs and drive ICs included in each of the light emitting blocks to be sequentially driven, and/or through efficient series-parallel connection between a limited number of LEDs.
