Abstract:
1. A lighting system comprising a plurality of non-networked LED lighting apparatuses connected to an A.C. power source, at least two LED lighting apparatuses of the plurality of non-networked LED lighting apparatus each comprising: a processor for monitoring at least one parameter of the A.C. power source, the at least one parameter selected from one of a periodically changing parameter of the A.C. power source and a transient signal of the A.C. power source, wherein the processor controls a lighting effect generated by the LED lighting apparatus by synchronizing the lighting effect in coordination with the at least one parameter of the power source, whereby the lighting system coordinates light output from the at least two LED lighting apparatuses based on the at least one parameter of the A.C. power source without requiring an additional coordinating signal.
