Abstract
A plurality of AC_LED units are coupled and disposed on a single chip to form an AC_LED system in single chip with three metal contacts to be driven by three-phase voltage sources. Alternatively, an AC LED system in single chip with four metal contacts is also disclosed to be driven by four-phase voltage sources.
