Abstract
A light-emitting system is introduced herein. The light-emitting system includes an insulating substrate and a plurality of light-emitting units electrically-connected on the insulating substrate. Each of the plurality of light-emitting units includes a plurality of light-emitting diodes arranged as a bridge rectifier. A first part of the plurality of light-emitting diodes emits light during positive half cycles of an AC power signal. A second part of the plurality of light-emitting diodes emits light during negative half cycles of the AC power signal. The third part of the plurality of light-emitting diodes comprising at least one light-emitting diode emits light during both the positive half cycles and the negative half cycles of the AC power signal, wherein the plurality of light-emitting units including the plurality of light-emitting diodes arranged as a bridge rectifier is formed together in a light-emitting chip.
