Abstract
The utility model relates to an electroluminescent device with simple production process and low cost, which consists of a main electrode, an auxiliary electrode, an insulating material, and a luminescent layer. The utility model is characterized in that the luminescent layer is applied behind the outer surface of the main electrode, and stored in the insulating material together with the auxiliary electrode.
Description
Technical field
The utility model relates to a kind of light-emitting device, particularly a kind of el light emitting device.
Background technology
At disclosed Chinese patent bulletin on July 18 calendar year 2001: disclose application number among the CN1304276A and be 99126253 patent application, a kind of " the colorful light of electroluminescent " is disclosed in this patent application, it is that a kind of barium titanate with good reflecting effect and high dielectric intensity is mixed with the material that can be coated on the wire by a certain percentage by selecting a kind of organic gel for use, then zinc sulphide and copper powder are added through preparation that another kind of organic gel is mixed with and to be coated in the barium titanate skin as luminescent layer, after treatment, the electrically conducting transparent sizing material that indium oxide or selenium oxide are caused evenly is coated in outside the luminescent layer again, electrically conducting transparent glue is outer around last metal electrode silk, put colourful transparent PVC material then, logical powering on can be luminous on inside and outside wire.The colorful light of existing this electroluminescent exists manufacturing process complexity, shortcoming that cost is high.
Summary of the invention
The purpose of this utility model is in order to solve the existing colorful light of electroluminescent, has manufacturing process complexity, problem that cost is high, and the el light emitting device that a kind of manufacturing process is simple, cost is low is provided.
Technical scheme:
The purpose of this utility model is achieved in that a kind of el light emitting device, comprises main electrode, auxiliary electrode, insulating material, luminescent layer, after it is characterized in that luminescent layer is coated in the main electrode outer surface, again in auxiliary electrode is hidden in insulating material.
Described el light emitting device is characterized in that described insulating material is a wire, and main electrode is coaxial with this wire insulating material, and described auxiliary electrode is parallel with main electrode.
Described el light emitting device is characterized in that the quantity of described auxiliary electrode is two or more.
Described el light emitting device is characterized in that described auxiliary electrode is uniformly distributed in around the main electrode.
Beneficial effect:
Owing to adopted technical scheme described in the utility model, to compare with existing electroluminescence wire, auxiliary electrode of the present utility model outside insulating barrier, has been simplified production technology without helical form, has been improved production efficiency, has reduced cost.
