A light-emitting diode (LED) based lighting device comprises a base 10, a connection section 11, at least one LED lighting module 20, and at least one control circuit 30. The LED lighting module is mounted to the base so that the base provides the LED lighting module with the functions of retention and heat dissipation. The control circuit is mounted to the base and is electrically connected to power wiring of the LED lighting module for ON/OFF switching of the LED lighting module and includes an AC to DC converter for supplying operation power. A shade (40, fig. 3) may be attached to the top of the base. The LED lighting module may comprise a single, multi-die packaged LED chip. |
