Abstract
An alternating current (AC) light emitting assembly and an AC light emitting device are disclosed. The AC light emitting assembly includes a substrate; a rectifier unit comprising a plurality of rectifier components arranged in a Wheatstone Bridge, for rectifying an AC signal into a direct current (DC) signal, each of the rectifier components having a high breakdown voltage and a low forward voltage; a light emitting unit electrically connected to the rectifier unit and comprising a plurality of light emitting components formed on the substrate, for emitting light when receiving the DC signal outputted by the rectifier unit; and two conductive electrodes electrically connected to the rectifier unit for receiving and transmitting the AC signal to the rectifier unit. The AC light emitting device includes two stacked and electrically connected AC light emitting assemblies.
