Abstract

The utility model relates to a film luminescent counterfeit-proof mark, which is composed of a luminescent chip, a mark layer, a power source connector, etc. The utility model is characterized in that the luminescent chip is a film electroluminescent device with multilayer structure, and the luminescent chip is composed of a plastic substrate, a conducting layer, a luminescent layer, a transparent conducting film, and a transparent plastic film; the mark layer is arranged on the transparent plastic film; the outer layer is a dampproof plastic package film; the conducting layer and the transparent conducting layer are separately connected with two poles led in by the power source connector; the luminescent layer is a layer of electroluminescent fluorescent powder; the mark layer is provided with patterns, characters, etc. The utility model has the advantages of compact structure, fine manufacture, brightness, and high discrimination. The utility model is an ideal feit-proof mark.

Description

The thin-film light emitting anti-counterfeiting mark

The utility model relates to a kind of thin-film light emitting anti-counterfeiting mark that is used for commodity counterfeit prevention.

The product that existing enterprise produces, in the market sale process, the commodity sign of its product and anti-counterfeiting mark are two objects independently separately, embody separately function and value respectively, and need to discern by extraneous light.Simultaneously, along with developing rapidly of science and technology, objectively cause himself protective capability of some anti-counterfeiting mark descending day by day, even lost anti-fake effect.

The purpose of this utility model is not enough and a kind of thin-film light emitting anti-counterfeiting mark is provided at above-mentioned technology, make its product mark and anti-counterfeiting mark become one, can strengthen the pseudo-function of Zhen of brand names and the authenticity of screening product effectively, ensure enterprise and consumer's rights and interests.

The purpose of this utility model is achieved in that a kind of thin-film light emitting anti-counterfeiting mark, it is made of luminescence chip, reference lamina, power connection etc., its luminescence chip is the thin-film electroluminescent device of sandwich construction, internal layer is a plastic base, the second layer is a conductive layer, the 3rd layer is luminescent layer, the 4th layer is nesa coating, layer 5 is an overlay, reference lamina is stacked on the overlay, skin is moistureproof plastic foil, and conductive layer is connecting the two poles of the earth that power connection is introduced respectively with nesa coating.The shape of luminescence chip can be circle, ellipse, prismatic, square, rectangle or other shape, and the luminescent layer in the luminescence chip is an electrofluor powder.Reference lamina is pattern, literal, numeral, portrait, animal picture or decorative layer.

Principle of work of the present utility model be when the two poles of the earth of the power connection that is connecting luminescence chip feed-in behind the electric current of voltage regulation and frequency modulation, produce electric field between conductive layer and the transparency conducting layer, directly the stimulated luminescence layer is luminous, light directive reference lamina, the pattern of reference lamina, literal, numeral, portrait, animal picture or decorative layer are in printing opacity or occlusion process, be shown stereo artistic effect clearly, the purpose that reaches the propaganda brand names and screen authenticity of products.

The utility model modern design, compact conformation is made meticulously, and light is pleasing, and examination property is strong, has certain effect of art appreciation, is desirable anti-counterfeiting mark.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the I-I cut-open view of Fig. 1.

Shown in Fig. 1～2, a kind of thin-film light emitting anti-counterfeiting mark, it is made of luminescence chip 1, reference lamina 2, power connection 3 etc., its luminescence chip 1 is the thin-film electroluminescent device of sandwich construction, internal layer is a plastic base 4, the second layer is a conductive layer 5, the 3rd layer is luminescent layer 6, the 4th layer is nesa coating 7, layer 5 is an overlay 8, reference lamina 2 is stacked on the overlay 8, and skin is sealed for moistureproof plastic packaging film 9 hot pressing, and conductive layer 5 is connecting the two poles of the earth that power connection 3 is introduced respectively with nesa coating 7.The shape of luminescence chip 1 can be circle, ellipse, prismatic, square, rectangle or other shape.Luminescent layer 6 in the luminescence chip 1 is an electrofluor powder.Reference lamina 2 is pattern, literal, numeral, portrait, animal picture or decorative layer.After each stacked closing, its edge becomes as a whole by the tackifier involution, has guaranteed the moisture seal and the usability of luminescence chip 1.
