Claim:
A method of driving a series of LEDs in an LED light string module using an AC current source and minimizing power loss comprising: providing a first adapter that is not connected to a full wave rectifier comprising: connecting a first lead of a first capacitor to a first power lead of said AC current source and not to a full bridge rectifier; connecting a second lead of said first capacitor to a first end of said LED string module and not to a full bridge rectifier; connecting an anode of a first diode, which is not part of a full bridge rectifier, to a second power lead of said AC current source; connecting a cathode of said first diode to said second lead of said first capacitor and said first end of said LED string module; providing a second adapter that is not connected to a full wave rectifier comprising: connecting a first lead of a second capacitor to said first power lead of said AC current source and not to a full bridge rectifier; connecting a second lead of said second capacitor to an anode of a second diode and a second end of said LED light string module and not to a full bridge rectifier; connecting a cathode of said second diode, which is not part of a full bridge rectifier, to said second power lead of said AC current source; selecting a capacitance tor said first capacitor that creates an impedance between said first power lead and said LED light string module that is sufficient to limit current through said LED light string module to prevent damage to said LED light string module and cause a positive voltage to be applied to said LED light string module whenever a voltage level on said first power lead exceeds a voltage level on said second power lead, so that said first capacitor functions as a voltage divider, which divides voltages between said first capacitor and said series of LEDs in said LED light string module, which allows said first adapter to be used with different numbers of LEDs in said LED light string module; selecting a capacitance for said second capacitor that creates an impedance between said first power lead and said LED light string module that is sufficient to limit current through said LED light string module to prevent damage to said LED light string module and cause a positive voltage to be applied to said LED light string module whenever said voltage level on said second power lead exceeds said voltage level on said first power lead, so that said second capacitor functions as a voltage divider that divides voltages generated by said AC current source between said second capacitor and said series of LEDs in said LED light string module, which allows said second adapter to be used with different numbers of LEDs in said light string module; connecting a first inductor in series between said first lead of said first capacitor and said first power lead; connecting a second inductor in series between a first lead of said second capacitor and said first power lead.
