Abstract

The utility model relates to a steel board electroluminescence body, which serves a low carbon steel board as a base board (a first electrode) whose upper surface are sprayed and sintered with a titanium white reflection layer, a dielectric layer, a luminescent layer, a transparent electrode (a second electrode) and a protective layer respectively. An electric conduction guide nail is penetrated to the second electrode from the steel board base board. The steel board electroluminescence body is firm, cares nothing for touch, can be randomly molded, and can be used for weak lighting or special displays for license plates, trademarks, instrument panels, etc.

Description

Steel board electroluminescence body

The utility model belongs to a kind of low-light (level) illuminating source.

In prior art, existing many people have worked out various forms of low-light (level) electroluminescence screens, patent " electroluminescent lamp " is declared (CN1031001A) and Britain Phosphor Products Co., Ltd. (GB) Dorset, England patent " electroluminescent device " of declaring in China patent such as (CN86105371A) by the Changchun Research Inst. of Physics, Chinese Academy of Sciences that announces as Chinese patent, it all makes the substrate of luminous element with glass, this substrate products made thereby is easily broken, directly influenced their range of application, moreover in the course of processing, should not adopt high-sintering process, therefore need to adopt the more expensive equipment of some prices, this has just strengthened the cost of product.

The purpose of this utility model is to overcome above-mentioned drawback, and the luminous element of a kind of solid durable, handling ease, the low-level lighting that has wide range of applications or demonstration is provided.

The project organization of this luminous element is: it comprises substrate, titanium white reflector, dielectric layer, luminescent layer, transparency electrode and protective layer, it is characterized in that this substrate is a steel plate, and as first electrode, titanium white reflector, dielectric layer, luminescent layer, transparency electrode and the protective layer of distinguishing spray sintering are successively arranged on the steel plate, mainly contain quartz, sodium tetraborate, zinc oxide and barium titanate in this titanium white reflector; Mainly contain silicon dioxide, boric acid in this dielectric layer; Mainly contain fluorescent material in this luminescent layer; This transparency electrode is second electrode, mainly contains butter of tin; This protective layer mainly contains silicon dioxide, brium carbonate and strontium nitrate; Conduction is drawn nail and penetrated to transparency electrode from substrate, and is stable for guaranteeing conduction, draws nail in conduction and wears to add to an end of transparency electrode and be coated with conductive silver paste, and this conductive silver paste is communicated with transparency electrode (second electrode) and conduction is drawn nail; Separate first and second electrode for insulation, draw to nail in conduction insulating case is housed.

Below in conjunction with description of drawings example structure of the present utility model:

Accompanying drawing 1 is the contour structures schematic diagram of this steel plate electroluminor.

Accompanying drawing 2 is that Fig. 1 is along A-A line cutaway view.

Wherein, 1 is substrate, adopts low carbon steel plate, and 2 is the titanium white reflector; 3 is dielectric layer; 4 is luminescent layer, and 5 is transparency electrode, and 6 is protective layer; each layer respectively successively spray sintering on substrate 1; conduction is drawn nail 7 and is penetrated conductive silver paste 8 to the transparency electrode from substrate 1, and conduction draws the outer dress of nail insulating case 9, with isolate steel plate with conduct electricity the conduction of drawing nail and contact.

The utility model is firm solid, be applicable to the various place low-level lighting or the uses such as display board photograph, trade mark, advertising design and panel board of easily pounding of easily bumping, it can make plane, sphere or other geometry with the need, easily decorating, throw light on, the visual angle is big, light is soft, brightness stability, life-span is long, and the substrate local damage does not influence luminous, as be used for that not only appearance looks elegant is beautiful on the motor vehicles licence plate, and do not have under the illuminating lamp situation at night, can be in the certain distance scope, clearly demonstrate license number, meet generally to bump and pound not impact effect.
