Decorative lighting system with lamps electrically connected to conducting wires by piercing connectors defining a plurality of parallel circuits

摘要

A lighting system (10) comprises a conduit (12) of at least two wires within a plastic cladding (13) and a number of lights (23) each comprising a lamp holder (14) attached to and in electrical contact with the wires of the conduit. The electrical connection means of each holder comprises pins (34, 36) of two different types, such that in a three wire system it is the subsequent orientation of the holder (14) with respect to the conduit (12) which will determine which pair of wires of the three wires is connected.
