US Patent 10454009 Parallel wire light string and method of manufacturer

A light set and method of manufacturer with first and second spaced apart conducting wire conducting wires with one of the wires having an insulated coating and the other bare uninsulated. An LED chip is surfaced mounted at intervals along the wires. The insulated wire has its insulation removed at the intervals which may weaken the wire. The bare wire does not require removal of insulation and thus remains stronger and resists kinking. Alternative structures and method of creating an insulated coating are disclosed.
