Patent ID: 8338836

Claim:
An alternating current (AC) light emitting device, in which a plurality of light emitting cells disposed on a substrate are flip-bonded to a submount substrate to be driven under an AC power source, the AC light emitting device comprising: a first serial array of light emitting cells; a second serial array of light emitting cells, the second serial array being connected in reverse parallel to the first serial array; bonding patterns disposed on the submount substrate, the light emitting cells of the first serial array and the second serial array being flip-bonded to the bonding patterns, at least one of the bonding patterns disposed on the submount substrate connecting a light emitting cell and an adjacent light emitting cell of the first array disposed on the substrate; and node connecting patterns disposed on the submount substrate, at least one of the node connecting patterns connecting one of the bonding patterns provided in the first serial array with another of the bonding patterns provided in the second serial array.
