Patent ID: 8736182

Claim:
A series wired light string comprising: (a) at least 30 light emitting diodes (LED's) connected in electrical series; and (b) a split bridge rectifying circuit for powering the series connected LED's, the split bridge rectifying circuit comprising: (i) a first half bridge rectifying circuit formed of two transistors as rectifying devices, using only the emitter and collector terminals of the transistors, with the base terminal not connected, and (ii) a second half bridge rectifying circuit formed of two transistors as rectifying devices, using only the emitter and collector terminals of the transistors, with the base terminal not connected; wherein the series connected LED's are connected between the first and second halves of the bridge rectifying circuit, and wherein the first half bridge rectifying circuit is connected to a first AC plug and the second half bridge rectifying circuit is connected to a second AC plug.
