Problems solved by technology

Moreover, the luminous brightness is easily blocked by the external electrodes, and the actual brightness utilization rate is not high
This kind of cold light also does not have some special functions, such as it cannot selectively emit light according to whether it encounters polar solvents (such as water) or conductive materials, which greatly limits the application of appliances

Embodiment 1

[0039] Such as image 3 The shown spiral electroluminescence wire includes a coaxial insulating support 1 , an electrode layer 2 , an insulating layer 3 and a light emitting layer 4 sequentially from the inside to the outside. The electrode layer 2 is composed of a copper wire 5 and a copper wire 6 with a diameter of 0.2mm spirally wound on the insulating support 1 (the surfaces of the copper wire 5 and the copper wire 6 are also conductive, and there is no insulating layer), and the two copper wires are not in direct contact. . The two copper wires can be spirally wound by hand, but in order to improve production efficiency, a special wire winding machine can be used for winding.

[0040]In the above embodiment, the material used for the insulating layer 3 is made of a solution obtained by uniformly mixing barium titanate and organic glue and diluting it to a suitable viscosity. The material used for the luminescent layer 4 is made of a solution obtained by uniformly mixing...

Embodiment 2

[0042] Such as Figure 4 The shown spiral electroluminescence wire includes a coaxial insulating support 1 , an electrode layer 2 , an insulating layer 3 and a light emitting layer 4 sequentially from the inside to the outside. The electrode layer 2 consists of two copper wires 5 and 6 with a diameter of 0.2mm (the surface is also conductive without an insulating layer), and a PE wire 8 with a diameter of 0.2mm sandwiched between the copper wire 5 and the copper wire 6 And PE wire 9 (for insulation, to prevent direct contact with copper wire). The four wires are helically wound on the insulating support 1, and the four wires are in close contact with each other. Manual method can be used for spiral winding, but in order to improve production efficiency, special winding machine can be used for winding.

Embodiment 3

[0045] Such as Figure 5 The shown spiral electroluminescence wire includes a coaxial insulating support 1 , an electrode layer 2 , an insulating layer 3 and a light emitting layer 4 sequentially from the inside to the outside. The electrode layer 2 is composed of two polyurethane enamelled copper wires 5 and 6 with a diameter of 0.17 mm. Such as Image 6 As shown, the polyurethane enameled copper wire (5 or 6) is divided into inner and outer two-layer structure, the inner layer is a copper wire 10 with a diameter of 0.15mm, and the outer layer is insulating polyurethane 11. These two copper wires (5 and 6) are helically wound on the insulating support 1 and are in close contact. Copper wire can be spirally wound by hand, but in order to improve production efficiency, a special wire winding machine can be used for winding.

[0046] In the above embodiment, the material used for the insulating layer 3 is made of a solution obtained by uniformly mixing barium titanate and org...

Abstract

The invention discloses a spiral electroluminescent wire, which comprises an insulating support, an electrode layer, an insulating layer and a light-emitting layer arranged in sequence from the inside to the outside, and the electrode layer includes a first wire and a second wire wound spirally on the insulating support . The spiral electroluminescence wire of the present invention has a large luminous area, a high utilization rate of luminous brightness, and has the function of emitting light when it encounters a polar solvent (such as water, etc.) or a conductive material, so that it has a wide application prospect in real life and can be used for decoration , It can also be used for warning and so on in rainy days.

Description

technical field [0001] The invention relates to the field of cold wires, in particular to a spiral electroluminescence wire. Background technique [0002] Cold light is a new generation of products in the field of international luminous display lighting, and its appearance is similar to ordinary telephone lines. The cold light can continuously emit light without any heat radiation when working, and the power consumption is only 50-70% of LED lights, 20-40% of string lights, and 1-10% of neon lights. The cold light emits evenly and delicately, the color is bright and rich. And users can assemble any pattern or text according to their needs. It can be folded and bent, knotted, cut, and spliced ​​at will. It can be changed frequently and reused, which is economical and environmentally friendly. [0003] At present, cold light has begun to be applied to many aspects of life. Such as: indoor and outdoor advertising text patterns, decoration of vehicles, boats and other vehicle...
