Patent ID: 7911151

Claim:
A switching LED cell, comprising: an input terminal operable to receive power at a first frequency, the first frequency being a single frequency; an output terminal; and at least one LED between the input terminal and the output terminal operable to radiate a first color of light in response to a LED current flowing through said at least one LED; and at least one switch between the input terminal and the output terminal; wherein said switching LED cell is operable to be switched between a radiating mode and a disabled mode at a LED driving frequency, wherein, during the radiating mode, the at least one switch controls flow of the LED current through said at least one LED whenever the power is applied between said input terminal and said output terminal, and wherein, during the disabled mode, the at least one switch impedes flow of the LED current through said at least one LED whenever the power is applied between said input terminal and said output terminal, wherein the at least one switch is a first at least one switch operable to be opened during the radiating mode and closed during the disabled mode, the switching LED cell further comprising: a second at least one switch operable to be closed during the radiating mode and opened during the disabled mode.
