Abstract

The invention discloses a polymer electroluminescent wire which comprises a central electrode wire, a light-emitting layer, a transparent conductive layer, an auxiliary electrode wire, a transparent polymer layer, and a transparent outer insulation layer. The central electrode wire is a linear conductor. The light-emitting layer is an insulated, conductive and transparent polymer and coats the central electrode wire. The transparent conductive layer coats the light-emitting layer. The auxiliary electrode wire is wound at the periphery of the transparent conductive layer. The transparent polymer layer coats the transparent conductive layer. The transparent outer insulation layer coats the transparent polymer layer.

In addition, polymers are used at multiple places and various protection layers are arranged, the polymer electroluminescent wire has the advantages of arbitrary bending, a long service life and safety and environmental-friendlyness, the polymer electroluminescent wire can be bent into various geometric shapes and patterns, a variety of colors can be selected, and the polymer electroluminescent wire is beautiful and novel and can be widely used for decoration.

Description

Polymer electroluminescent luminous line

Technical field

The present invention relates to a kind of electro luminescence line, more particularly to a kind of utilization polymer is the polymer electroluminescent luminous line of luminescent material.

Background technology

Linear luminophor is the first-selection of house ads Upholstering design, in the multicoloured ad decoration world, its color glittering continuous change energy moment leaves unforgettable impression of looking over so as to check to consumer, here it is the purpose of advertisement, certainly also will be by the unique design concept of designer, along with the various art patterns using Linear luminophor torsion structure, by the control of optimal luminance level and time, artistic is presented in face of people, if illumination light is improper, or cause dazzling dazzling the eyes to make one to feel that dizziness is felt bad, accordingly even when being also to lose artistic elegance because illumination is improper with outstanding advertisement design, even bizarre and motley phenomenon occurs.

With the development of society, people utilize electroluminescent (English electroluminescent, abbreviation EL) principle has been manufactured into electroluminescent light source, and progressively using its technical substitution neon light, electroluminescent light source is the AC field that a kind of alternating voltage by being added in the two poles of the earth is produced, excite electron collision fluorescent material, so as to being led to the electric transition for making energy pole, change, being combined, further launch the light source of high efficiency cold light, widely used electroluminescent light source mainly has the type such as the EL sheet of sheet and the electro luminescence line of wire.

At present, the luminescent layer of existing electro luminescence line is mostly mixed using fluorescent type plastic grain and corresponding binding material, due to the hole full of air can be left after the binding material part volatilization in luminescent layer, these holes can reduce the field of light source and send a telegraph appearance and form small blackening stain, but also can form multiple discontinuous optics breakpoints on isolychn, cause isolychn that refraction, scattering even full transmitting phenomenon occurs, cause light loss of energy, the final brightness for reducing electro luminescence line.In order to solve the defect that the space in above-mentioned luminescent layer is brought, the Chinese invention patent of Publication No. CN1182343A provides a kind of electro luminescence line, it is come filling pore using the liquid with viscosity to constitute one of main points of the isolychn, but using the liquid of this viscosity come filling pore, there are following several respects：

1. because the pore size formed in luminescent layer differs, and the particle diameter of the liquid filler for being adopted is often more than the diameter of a part of hole, so will necessarily some space cannot fill, cause the optical energy loss at this part hole still to exist, blackening stain cannot be eliminated；

Even if being 2. filled with liquid filler in space, new electric field will not be formed around space due to this neutral filler to encourage fluorescent grain to light, therefore its brightness improving limited extent to electro luminescence line；

3. liquid filler both can be penetrated into easily in hole, easily can also leak out from hole or evaporate, in order to effectively prevent the loss of liquid filler, also need to apply a kind of transparent viscosity insulating materials outside luminescent layer as barrier layer, which not only adds the complexity of electro luminescence line, and also add the difficulty of its manufacture craft, more importantly barrier layer also stops or has scattered the light that part luminescent layer is sent while filler is stopped, and have impact on the overall brightness of electro luminescence line.

Therefore, it is badly in need of a kind of luminescent layer imporosity and electro luminescence line that also set insulation, conductive, transparent performance are integrated.
