PROBLEM TO BE SOLVED: To provide a light-emitting element, in more detail, an AC light-emitting element in which a plurality of arrays having different numbers of light-emitting cells are employed to increase light emission time and to reduce light flicker effect.SOLUTION: A light-emitting device comprises: an external power supply; a rectification part rectifying the external power supply and outputting a rectification voltage; a light-emission part having a first light-emitting cell block and a second light-emitting cell block each having light-emitting cells 30 connected in series, and emitting light having the same wavelength band; and a switch part connected to one end of the rectification part and one end of the light-emission part. The first light-emitting cell block and the second light-emitting cell block emit light at different voltages alternately. |
