Claim 87:
88. The LED lighting device according to claim 84, wherein the at least one short power interruption signal is generated by a push button or a touch sensor electrically coupled with a second controller electrically coupled with a bi-directional semiconductor switching device to control a conduction state of the bi-directional semiconductor switching device electrically connected between an AC power source and an AC/DC power converter, wherein when the push button or the touch sensor is operated for a short time interval, a voltage signal with a time length equal to the short time interval is detected by the second controller, wherein upon receiving the voltage signal, the second controller operates to instantly cutoff a conduction of the bi-directional semiconductor switching device and re-conduct the bi-directional semiconductor switching device within the short time interval to generate the at least one short power interruption signal detected by the power interruption detection circuit, the controller accordingly operates to alternately perform the corresponding diffused light color temperature performance in the diffused light color temperature switching scheme according to the prearranged sequence.
