ABSTRACT:
The present invention describes a light emitting diode illumination apparatus made of a light bulb base, a heat dissipating device, a plastic lid, a drive substrate, a metal substrate, a circular insulated base and a casing, and the heat dissipating device is in contact with the metal substrate in normal conditions, such that the heat source produced by each light emitting diode is conducted to the heat dissipating device through the metal substrate and then conducted from the heat dissipating device to the light bulb base for effectively dispersing the heat source and maintaining the light emitting efficiency of each light emitting diode.
