Abstract
An alternating current (AC) light emitting device is revealed. The AC light emitting device includes a substrate and a plurality of light emitting units arranged on the substrate. The light emitting unit consists of a first semiconductor layer, a light emitting layer, a second semiconductor layer, at least one electrode and at least one second electrode respectively arranged on the first semiconductor layer and the second semiconductor layer from bottom to top. The plurality of light emitting units is coupled to at least one adjacent light emitting unit by a plurality of conductors. By the plurality of conductors that connect light emitting units with at least one adjacent light emitting unit, an open circuit will not occur in the AC light emitting device once one of the conductors is broken.
