摘要: An AC LED package structure includes a heat-sink slug, an AC LED module, a positive-electrode frame, a negative-electrode frame, and an insulation submount. The AC LED module is electrically connected with the positive-electrode frame and the negative-electrode frame, respectively. The insulation submount is interposed between the AC LED module and the heat-sink slug. The insulation submount is characterized by having a voltage-resistance value greater than 1000 volts. Therefore, it is possible to prevent the AC LED chip of an AC LED device from being broken through by high voltage, causing an electric shock if a human body touches the AC LED device. And moreover, the AC LED device can satisfy the requirements of a certified safety specification.
