Abstract
A series connected LED light string using capacitors as shunts. The shunts are implemented by inserting a capacitor—for example a low breakdown voltage chip capacitor—in every light socket, or internally within each LED. The capacitive shunt continues current in the light string in the event an LED fails by opening electrically—the capacitor shorts out, thus, keeping the string of lights illuminated. The shunt capacitor across the LED also helps filter the pulsating DC voltage to the bulbs and reduces annoying flicker.
