Abstract
A light emitting diode (LED) bulb includes a heat sink, a circuit layer having two opposite sides, multiple LEDs mounted on one side and an electrical insulating layer connected between the opposite side and the heat sink. Heat generated by the LEDs is conducted to the heat sink through the circuit layer and the electrical insulting layer and is dissipated quickly. Further, a fan can be mounted on the fins to dissipate heat from the heat sink more quickly. Therefore, the LED bulb has good heat dissipating efficiency.
