Claim Text:
1. An LED lighting system comprising: a bridge rectifier directly coupled to an AC line power source and providing a rectified signal, the AC line power source having a power cycle; a string of LEDs comprising a first, second, and third set of LEDs, the cathodes of the first set of LEDs directly, electrically connected to the anodes of the second set of LEDs, the cathodes of the second set of LEDs directly, electrically connected to the anodes of the third set of LEDs, the cathodes of the third set of LEDs connected to the bridge rectifier; a first current limiting device coupled directly to the bridge rectifier receiving the rectified signal from the bridge rectifier, the first current limiting device coupled directly to the anode of the first set of LEDs and configured to provide a first limited current to the first, second, and third set of LEDs during a first portion of the power cycle; a second current limiting device coupled directly to the bridge rectifier receiving the rectified signal from the bridge rectifier, the second current limiting device coupled directly to the anode of the second set of LEDs and configured to provide a second limited current to the second and third set of LEDs during a second portion of the power cycle; and, a third current limiting device coupled directly to the bridge rectifier receiving the rectified signal from the bridge rectifier, the third current limiting device coupled directly to the anode of the third set of LEDs and configured to provide a third limited current to the third set of LEDs during a third portion of the power cycle.
