Abstract:
1. A light-emitting device, comprising: a first power source connection terminal and a second power source connection terminal, the first and second power source connection terminals configured to be connected to an external power source; a plurality of light emitting cell arrays, each of the plurality of the light emitting cell arrays being connected in parallel to one another between the first and the second power source connection terminals, each of the plurality of light emitting cell arrays comprising serially connected light emitting cells, each of the light emitting cells comprising; a switching block connected to the first power source terminal, the second power source connection terminal, and each of the light emitting cell arrays, wherein a first group of the light emitting cell arrays are connected in parallel to the switching block and a second group of the light emitting cell arrays are connected in reverse parallel to the switching block, wherein the switching block is configured to sequentially turn on and off each of the plurality of light emitting cell arrays when an alternating current (AC) voltage is applied to the light emitting device, and wherein each of the plurality of light emitting cell arrays is disposed on a single substrate.
