Patent ID: 8314564

Claim:
A capacitive full wave LED light string that drives a series of LEDs with an AC current source without using a full bridge rectifier comprising: an LED string module; a first adapter that is not connected to a full bridge rectifier comprising: a first capacitor having a first lead connected to a first power lead of said AC current source and a second lead connected to a first end of said LED string module, said first capacitor having a capacitance that creates an impedance between said first power lead and said LED string module that is sufficient to limit current through said LED string module to prevent damage to said LED string module and cause a positive voltage to be applied to said LED string module whenever a voltage level on said first power lead exceeds a voltage level on a second power lead of said AC current source; a first diode having a cathode connected to said first end of said LED string module and an anode connected to said second power lead; a second adapter that is not connected to a bridge rectifier comprising: a second capacitor having a first lead connected to said first power lead and a second lead connected to a second end of said LED string module, said second capacitor having a capacitance that creates an impedance between said first power lead and said LED string module that is sufficient to limit current through said LED string module to prevent damage to said LED string module and cause a positive voltage to be applied to said LED string module whenever said voltage level on said second power lead exceeds said voltage level on said first power lead of said AC current source; a second diode having a cathode that is connected to said second power lead and an anode that is connected to said second end of said LED string module; a first resistor connected in series between said first lead of said first capacitor and said first power lead; a second resistor connected in parallel with said first capacitor; a third resistor connected in series between said first lead of said second capacitor and said first power lead; a fourth resistor connected in parallel with said second capacitor.
