Abstract
The invention relates to a light emitting diode (LED) illumination device directly driven by alternating current (AC). The LED is characterized in using a diode to prevent the LED from being damaged by negative voltage of AC, so that the LED can be directly driven by AC power source in order for illumination. Because each LED of the invention is always in a halt-working state, the heat dissipation problem of the LED is effectively solved and the lifetime of LED is extended accordingly.
