Patent ID: 8643291

Claim:
A high-voltage alternating current light-emitting diode (AC LED) structure, comprising: a circuit substrate; and a plurality of AC LED chips fixed to and electrically connected to the circuit substrate and forming a series-connected circuit by means of the circuit substrate, the AC LED chips each comprising: an insulated substrate; at least one LED set having a first LED and a second LED, wherein the first LED and the second LED are disposed on the insulated substrate and insulated and separated from each other; at least one first metal layer forming a first shape layout and having a first end portion and a second end portion, the first end portion being disposed on a first transparent conductive layer of the first LED, and the second end portion being disposed on a second n-type layer of the second LED; and at least one second metal layer forming the first shape layout and having a third end portion and a fourth end portion, the third end portion being disposed on a second transparent conductive layer of the second LED, and the fourth end portion being disposed on a first n-type layer of the first LED.
