A power interruption protection structure for an LED string light implements a Zener diode connected between an anode and a cathode inside or outside a casing of each of plural monochromatic or polychromatic LEDs that are connected in series to form the LED string light. In case of a burnout or breakdown of one of the LEDs, the Zener diode provided at the malfunctioning LED serves to instantly restore electrical conduction, allowing the LED string light to function normally without interruption. Accordingly, failure of one or some of the LEDs does not affect the LED string light as a whole. |
