Abstract

A highly bright electroluminescent wire includes a metal core electrode, an internal electron-emitting layer, an internal highly dielectric layer, a glowing layer, an external highly dielectric layer, an external electron-emitting layer, a transparent conductive layer, an electrode of external conductive layer, a transparent protective plastic layer and a color fluorescent transparent plastic layer orderly coated around the metal core electrode. The metal core electrode and the electrode of external conductive layer are charged with a voltage of AC50-400V and a frequency of 0.05 KHz to 20 KHz to produce a colored highly bright light.
