DECORATIVE LIGHT STRING HAVING SHUNT REPAIR DEVICE

摘要

One or more strings (G1-GN) of decorative lights (L1-L8) are supplied withpower from a standard residential power by means of a power supply (10), whichsupplies the power to at least one pair of parallel conductors (11, 12), suchconductors in turn delivering the power to the light strings (G1-Gn). Thelight strings (G1-Gn) are connected in parallel between the conductors (11-12)with each light (L1-L8) being connected in series in the light strings (G1-Gn). A repair device for fixing a malfunctioning shunt across a decorativelight (L1-L8) includes a high-voltage generator producing pulses of a greatermagnitude than the normal operating voltage. The pulse generator may be apiezoelectric pulse generator, a battery powered electronic pulse generator,and/or an AC-powered electrical pulse generator.
