Most solid-state light emitting devices operate under direct current (DC) condition now. We report the alternating current (AC) light emitting devices fabricated with a diode bridge circuitry which is also made of light emitting diodes (LEDs). The LED bridge circuitry which is flipped on a silicon submount is composed of 4 branches with 7 LED chips and participates as a light emitting component as well. The AC LED can be operated with radiant flux of 0.83 W at an electric power of 8.5 W. This concept could be applied to fabricate compact and economical AC LEDs for a solid-state illumination.
