Abstract
A light emitting diode bulb comprises a heat sink, an insulator cover, a light emitting device package, a plurality of conductive terminals, a driving circuit, a holder, a metal screw thread, and an electrode. The light emitting device package, disposed between the insulator cover and heat sink, is covered by the insulator cover which exposes a portion of the light emitting device package. The conductive terminals are connected with the insulator cover and extend outwardly to be connected with the light emitting device package. The driving circuit converts an AC signal into a DC signal and includes upper conductive rods and lower conductive rods. The conductive rods are connected with the conductive terminals. The holder is connected with the metal screw thread and heat sink. The metal screw thread is connected electrically to one of the lower conductive rods. The electrode is connected electrically to the other lower conductive rods.
