摘要：An Alternate Current (AC) white Light-Emitting Diode (LED) device is provided,which belongs to the technical field of white LED manufacturing. The problem to besolved by the present invention is to low-costly overcome a series of deficiencies such as
the stroboflash of an AC driven LED, and the heat dissipation difficulty caused by anintegrated packaging of multiple LEDs. A white LED unit includes an LED chip and a lightemitting material that can emit light when being excited by the LED chip. The luminouslifetime of the light emitting material is 1˜100 ms. The LED chip only comprises one PNjunction. The light emitted by the LED chip is mixed with the light emitted by the lightemitting material to form white light. The white LED unit is driven by AC with a frequencynot more than 100 Hz. The white LED device of prevent invention uses the single PNjunction chip, rather than the prior integrated packaged AC multi-LED chip.
