Abstract
A light emitting device includes a plurality of micro diodes, which are electrically connected to constitute a bridge rectifier circuit. Each branch of the bridge rectifier circuit includes a single micro diode or a plurality of micro diodes. The light emitting device is electrically connected to an AC power source, which alternately drives the light emitting device in two current loops. Therefore, the micro diodes in two current loops of the bridge rectifier circuit emit light by turns.
