Abstract
An LED lighting system is provided for connection to a variable power source providing input power, the LED lighting system having 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 then control the current control circuitry according to the comparison result.
Claims12
Plural controllers connected to an LED lighting system, the controllers being configured to:
- provide an output to the LED lighting system;
- control one or more characteristics of the output, the characteristics being selected from the group comprising voltage amplitude, power frequency, and pulse width;
- and
- detect a change of the one or more characteristics of the output to identify a working status of the LED lighting system to synchronize a control status of the plural controllers in the LED lighting system.
An LED lighting system comprising:
- a support structure;
- at least one LED array on the support structure;
- an input power source providing input power for the at least one LED array;
- plural controllers connected to the input power source and configured to condition the input power, the plural controllers comprising power analyzing and current control circuitry, the power analyzing and current control circuitry 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 providing current control for at least a corresponding set of LEDs in the at least one LED array according to the comparison result.
