1. A light emitting diode, comprising:
- a first array of light emitting cells arranged on a substrate; and
a wire to connect the light emitting cells to one another,wherein the first array comprises at least two light emitting cells connected in series to one another through the wire,wherein one light emitting cell is spaced apart from a first adjacent light emitting cell in a first direction by a distance in a range of 10 μ
m to 30 μ
m,wherein the one light emitting cell is spaced apart from a second adjacent light emitting cell in a second direction substantially perpendicular to the first direction by a distance in a range of 10 μ
m to 30 μ
m, andwherein the light emitting diode is configured to operate on alternating current (AC) power.

Abstract
Disclosed herein is an AC light emitting diode. The light emitting diode comprises a plurality of light emitting cells two-dimensionally arranged on a single substrate. Wires electrically connect the light emitting cells to one another to thereby form a serial array of the light emitting cells. Further, the light emitting cells are spaced apart from one another by distances within a range of 10 to 30 μm, and the serial array is operated while connected to an AC power source. Accordingly, the excellent operating characteristics and light output power can be secured in an AC light emitting diode with a limited size.
