Abstract
A light emitting diode (LED) package includes a first serial array of light emitting cells formed on a first substrate to emit light of a relatively short wavelength, and a second serial array of light emitting cells formed on a second substrate to emit light of a relatively long wavelength. The first and second serial arrays are connected to in reverse parallel. The LED package is capable of being operated under AC power and emitting white light with excellent color reproduction characteristics and luminous efficiency.
