Method for preparing multi-core electroluminescent wire

Abstract

The invention discloses a method for preparing a multi-core electroluminescent wire. The multi-core electroluminescent wire comprises a plurality of metal core wire electrodes, luminous insulating layers, a luminous layer, a metal oxide transparent conductive layer, external conductive layer electrodes and a color fluorescent transparent plastic layer. The method is characterized in that the luminous insulating layers are uniformly coated on the surfaces of all metal core wire electrodes with the same diameter or different diameters; the metal core wire electrodes are spirally arranged regularly and twisted into a whole; the luminous layer is coated on the surface of the integrated metal core wire electrodes at one time; the metal oxide transparent conductive layer is coated outside the luminous layer; the metal oxide transparent conductive layer is contacted with the external conductive layer electrodes which are arranged linearly, and sealed by the color fluorescent transparent plastic layer; and a multi-channel special driver is connected to the metal core wire electrodes and the external conductive layer electrodes, consists of a high-frequency transformer, an inductor, a capacitor and a flash chip, outputs 130V alternating current (AC) voltage and 1,000Hz frequency, and controls energization to emit regular strong and weak light and dynamic, color and high-brightness light. The method can be widely applied to the fields of luminous clothes, advertisements, safety marks, household appliances and luminous electric wires.

Description

technical field [0001] The invention belongs to the technical field of electroluminescent devices application. Background technique [0002] Electroluminescent wire, also known as electroluminescent wire, cold light, EL wire, etc., is a new generation of products in the field of luminous display lighting. Its appearance is similar to that of ordinary telephone wires. Heat radiation, low power consumption, soft, foldable and bendable, free knotting, cutting, splicing and other characteristics, so it is widely used by people. [0003] The structure of the existing electroluminescent wire mainly includes: a metal core electrode, an insulating medium layer, a luminescent layer, a transparent conductive layer, and a wound outer electrode. The metal core electrode and the winding outer electrode will generate light when electrified. This structure, material and formula have been clearly described in Chinese patents 01133342.1, 200680032428.8, 200410099233.8, 200510019319.X and so...

AI Technical Summary

Problems solved by technology

The start-up voltage of the existing light-emitting lines is usually above 50V, and the contradiction between brightness and insulation is one of the important reasons that restrict the large-scale use of devices

The existing flashing electroluminescent wires are usually prepared by preparing the luminescent core with the insulating layer and the luminescent layer, and then winding and combining multiple wires. The actual operation is difficult and the yield is low. The surface is not smooth. It is obviously reflected on the surface, and the conductivity is poor; or simply winding and combining the finished electroluminescent wires, it is impossible to achieve the change of the intensity of the luminous wires.
