Abstract:
1. A Light Emitting Diode (LED) lighting control system comprising: a plurality of LEDs wherein electronic current flow to each individual LED of said plurality of LEDs is controlled by separate LED drive cell; all system signals are transmitted via serial connections; said each LED drive cell is sequentially connected one after another wherein only one lead LED drive cell connects to the host controller; the host controller transmits displaying signals to the lead LED drive cell; and the displaying signals are transmitted to said each individual LED as signal scanning-flow; lighting color of said each individual LED is selected from the group consisting of red, green, and blue; said each LED drive cell comprises a shift register wherein the shift register stores lighting status of the LED controlled by said each LED drive cell; the lighting status is stored until a different displaying signal is received by the LED drive cell wherein the lighting status is stored; said each LED drive cell comprises at least one replica current module, and at least one justification memory, and at least one image data memory, and at least one logic operator, and at least one binary control memory; said host controller transmits LED justification data to the at least one justification memory; and said host controller transmits displaying data to the at least one image data memory.
