Patent ID: 6957001

Claim:
A color-changing and multi-colored electroluminescent cable, comprising: a core wire made of soft metal or polymer as the central axis; a group of electroluminescent filaments consisting of a plurality of electroluminescent filaments of different colors which are insulated from each other and helically wound on the outer side of the axis; a transparent and flexible polymer casing tube disposed on an outer side of the group of electroluminescent filaments to form a flexible light emitting cable; and wherein each electroluminescent filament of said plurality of electroluminescent filaments of said group of electroluminescent filaments comprises: a metal conductive wire as a core wire and a first electrode; a medium insulating layer, which is made of an insulating mixture with improved density, coated on the core wire; a light emitting layer, which is made of a light-emitting mixture with improved density, coated on the medium insulating layer; a conductive layer, which is made of a semi-transparent, semi-solid viscous conductive polymer containing Au and methyl methacrylate, coated on the light emitting layer; one or more transmission conductive wires wound at interval on the conductive layer and led out as a second electrode; a color polymer casing tube disposed on the transmission conductive wires and the conductive layer.
