  • Light emitting diode assembly using alternating current as the power source
    Patent number: 7264381
    Abstract: An LED assembly includes a first LED unit and a second LED unit, the latter is coupled electrically to the first LED unit in such a manner that each of the first and second LED units defines a current-flow direction in reverse order so that once Alternating Current is applied, the first and second LED units are illuminated alternately by virtue of the positive and negative voltages of the Alternating Current.
    Type: Grant
