ABSTRACT:
An LED lighting device comprises a seat with a conductor. A light emitting diode is disposed on the conductor of the seat, and has an upper positive conductive pad, a lower negative conductive pad, and an insulating pad disposed between the positive and negative conductive pads. The lower negative conductive pad of the light emitting diode connects with the conductor. An exterior enclosure is disposed on top of the seat in such a way that a bottom end of the exterior enclosure is in contact with the upper positive conductive pad. A through hole is defined through the bottom end of the exterior enclosure for receiving the light emitting diode. The bottom of the seat is connected with a metal plate that is in contact with the conductor.
