Patent ID: 8791650

Claim:
An LED lighting system for connection to a variable power source providing input power, comprising: at least one LED array extending along a support structure spanning between a first end and a second end, the support structure made of rigid material, the support structure being sufficiently heat conductive to provide heat dissipation for LEDs in the at least one LED array; an electrical connector for connection to the variable power source at least at the first end or between the first end and the second end; power control circuitry for the at least one LED array, the power control circuitry being carried by the support structure and being in electrical communication with the electrical connector; a circuit board supporting the at least one LED array, the corresponding power control circuitry being provided on the circuit board or on a separate board; the at least one LED array being divided into sets of LEDs; the power control circuitry being formed of one or multiple current controllers, each of the one or multiple current controllers providing current control for a corresponding set of LEDs in the LED array; and at least one power analyzing and processing circuitry connecting to the variable power source and being configured to: identify one or more characteristics of the input power, where the characteristics are selected from amplitude, frequency, and pulse width of the input power, compare one or more of the characteristics of the input power to preset control criteria either in hardware or software or both to yield a comparison result, and control the current control circuitry according to the comparison result.
