Abstract
The present invention provides a high-voltage alternating current light-emitting diode (AC LED) structure. The high-voltage AC LED structure includes a circuit substrate and a plurality of AC LED chips. The AC LED chips each include an insulated substrate, an LED set, a first metal layer and a second metal layer. The AC LED chips manufactured by a wafer level process are coupled to the low-cost circuit substrate to produce the downsized high-voltage AC LED structure.
