Abstract

A device of electroluminescence ligament is a continuous base body plated with metal decorative layer on it coated with a media layer which is coated with luminescent layer, said luminescent layer is of least one or above colours of electroluminescence material and is covered with a transparent conducting layer which is connected with one to four conductive wires for outer layer protection, the outermost layer is sealed by transparent or semi-transparent tube. It has the merits as of the realization of colouration in structure and method on single silk thread body, as of high strength of luminescence and in various colours for to be used in display, advertisement and as a indicating mark.

Description

Electroluminescent filament device

Technical field the invention belongs to the electroluminescent technology in the shiner Neo-Confucianism.

Background technology electroluminescent device people often are called electroluminescent device again, the present invention is a kind of electroluminescence (english abbreviation EL) filament device, it is called linear device of electroluminescence or electroluminescent filament light source again, and it and plane or point-source of light electroluminescent device have bigger difference.Patent USWO97/24015, CN1182343, CN1209527, CN1304276 have set forth structure, characteristics, the purposes of device respectively, their colorize is all from outer colored plastic sleeve pipe, its luminous intensity has the 50%-80% loss, and the monomer silk thread cannot multicolor, multicolor needs the silk thread combination more than two to realize, Chinese patent application number 01250547.1 has realized colorize on monomer structure, but its production technology is very complicated.

Summary of the invention the invention provides a kind of electroluminescent filament device, to solve the problems of the technologies described above, has promptly realized the method and the structure of colorize on the monomer silk thread, and it is simple that it has technology, and effect is good, luminous intensity height, the characteristics that color is various.The technical scheme that the present invention takes is: a continuous baseline body 1; its surface is coated with metal decorative layer 2; scribble dielectric layer 3 on this metal decorative layer; dielectric layer scribbles luminescent layer 4 outward; this luminescent layer is one or more multiple color electroluminescent materials at least; luminescent layer has transparency conducting layer 5 outward, and this transparency conducting layer links to each other with 1～4 outer layer protection conductive wire body 6, and outermost layer seals with transparent or semitransparent pipe 7.

The invention has the advantages that: novel structure, on the monomer silk thread, realized the method and the structure of colorize, it is simple that it has technology, and effect is good, luminous intensity height, the characteristics that color is various.Can be widely used in fields such as demonstration, advertisement, Warning Mark.
