  • Patent number: 11965271
    Abstract: A flexible electroluminescent fiber for embroidery sequentially includes: metal core wires, a light-emitting layer, a transparent conductive layer, a filament, and a protective paint, wherein a quantity of the metal core wires is an even number, and the metal core wires are pasted together before being wrapped by the light-emitting layer; the light-emitting layer is coated with the transparent conductive layer; the protective paint and the filament are exterior to the transparent conductive layer; the metal core wires emit light through energizing; a diameter of the electroluminescent fiber is 0.1-0.3 mm, and a 20-36V safe voltage is applied for emitting light. The flexible electroluminescent fiber of the present invention has sufficient tensile force, and smooth and soft surface. Appearance and hand feeling of the present invention are the same as those of clothing textile fibers.

  • Patent number: 9445186
    Abstract: An electroluminescent earphone with a bending-resistance and a high-brightness includes earphone wires having bending-resistant electroluminescent wires, earbuds, an electroluminescent wire driver and an audio inputting plug. Each bending-resistant electroluminescent wire includes: a plurality of central electrodes; a luminescent layer coated on outer surfaces of the central electrodes; a transparent conductive layer coated on an outer surface of the luminescent layer; an outer electrode made of a plurality of wires arranged on an outer surface of the transparent conductive layer; and a transparent plastic covering the outer electrode and the transparent conductive layer. The bending-resistant electroluminescent wire is parallel with an earphone audio wire or coils around an outer surface of the earphone audio wire. A colored transparent plastic covers the bending-resistant electroluminescent wire and the earphone audio wire to form the earphone wire having the bending-resistant electroluminescent wire.
