LED lighting system

摘要

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 for connection to a variable power source providing input power, the variable power source being configured to represent a desired control setting with the input power by varying one or more characteristics of the input power, the LED lighting system comprising:
a support structure spanning between a first end and a second end; at least one LED array extending along the support structure; 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 at least an electrical connector for connection to the variable power source; and the power control circuitry being configured to compare the input power to one or more pre-set conditions to yield a comparison result indicating the desired control setting represented by the input power and output a control signal according to the comparison result.
