摘要：
An AC light emitting device includes a first light emitting diode chip and a second light emitting diode chip, each of which has a plurality of light emitting cells on a single substrate. A first long-persistent phosphor is positioned on the first light emitting diode chip to perform wavelength conversion for a portion of light emitted from the first light emitting diode chip, and a second long-persistent phosphor is positioned on the second light emitting diode chip to perform wavelength conversion for a portion of light emitted from the second light emitting diode chip. The afterglow luminescence period of the second long-persistent phosphor is different from that of the first long-persistent phosphor.
