Claim 86:
87. The LED lighting device according to claim 84, wherein the at least one short power interruption signal is generated by a wireless external control signal designed to control a conduction state of a bi-directional semiconductor switching device electrically connected between an AC power source and an AC/DC converter electrically connected to the LED driver circuitry, wherein the wireless external control signal is received by a wireless external signal receiver electrically coupled with a second controller electrically coupled with the bi-directional semiconductor switching device, wherein upon receiving the wireless external control 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 a predetermined time interval to generate the at least one short power interruption signal detectable by the controller thru 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.
