US Patent 7963670 Bypass components in series wired LED light strings

Disclosed is an LED light string that uses parallel connected bypass components that are connected across the leads of the LEDs and are disposed in the socket of the LED lamp holder. The use of parallel connected bypass components across the leads of the LEDs greatly enhances the reliability of the light string. Bypass components are also included in the LED lamp structure, both internally to the LED lamp proxy and externally across the leads of the LED lamp element. A resistive wire can also be connected between conductors in an LED socket structure inside a lamp holder. Using the bypass components, twinkle lamps can be inserted in series wired LED light strings.
