Abstract: An AC driven light emitting diode light apparatus, and its AC driven light emitting diode package element therein are provided. The AC driven light emitting diode package element includes a heat sinking substrate, a chip set, a pair of electrodes, and a package body. The heat sinking substrate has a fixing flange extended from a rim of the heat sinking substrate for fixing the heat sinking substrate on a support. The chip set is on the heat sinking substrate. The conductive electrodes are respectively set at two opposite sides of the heat sinking substrate. The package body envelops the heat sinking substrate, the chip set and a part of the conductive electrodes to be one.
