LED lighting system
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.
1. 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.
2. The LED lighting system of claim 1 comprising two or more controllers, each controller being configured to control the LED lighting system synchronously.
3. The LED lighting system of claim 1 in which the controllers are connected in series.
4. The LED lighting system of claim 1 in which the controllers are connected in parallel.
5. The LED lighting system of claim 1 in which at least one controller is configured for remote control through a network.
6. The LED lighting system of claim 1 in which at least one controller is installed on the support structure of the LED lighting system.
7. The LED lighting system of claim 6 in which the at least one controller installed on the support structure of the LED lighting system is mounted on a PCB that also mounts at least one LED array of the LED lighting system.
8. The LED lighting system of claim 6 in which the at least one controller installed on the support structure of the LED lighting system is mounted on a PCB that does not also mount at least one LED array of the LED lighting system.
9. The LED lighting system of claim 1 in which the LED lighting system is formed in a shape that is one or more of cylindrical, rectangular, oblong, globe-shaped, triangular, disc-shaped, light-bulb-shaped, straight bendy, and zig-zag line-shaped.
10. The LED lighting system of claim 1 further comprising plural support structures each having at least one LED array.
