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.

10. A light-emitting system, comprising:
-
an insulating substrate; and a plurality of light-emitting units formed on the insulating substrate, each of the plurality of light-emitting units comprising a plurality of light emitting diodes, wherein a first part and a third part of the plurality of light-emitting units are coupled to a first current path, and a second part and the third part of the plurality of light-emitting units are coupled to a second current path, thereby the plurality of light-emitting diodes in the first part and the third part and the plurality of light-emitting diodes in the second part and the third part emit light alternatively when an AC power signal is applied to the light-emitting system;
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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
