An anti-counterfeit photoflash device

Abstract

The invention discloses an anti-counterfeit photoflash device, including a housing and a light guide channel arranged in the housing, wherein one end of the light guide channel is connected with a light condensing block inputted from a light source, the other end is connected with a light transmitting block outputted from the light source, the light guiding channel includes a plurality of first light guiding strips connected with the light condensing block and a flash switch connected with the light transmitting block, and the flash switch includes a key and a plurality of second light guidingstrips arranged on the key and connected with the light transmitting block and the first light guiding strips. The device is novel in design, simple in structure and convenient in operation. By connecting a light source on one side of the condensing block, the light source passes through the light guide channel, and the light guide bar partially connected on the flasher transmits the connected part of the light source to the light guide plate, so that a part of the anti-counterfeit identification code on the light guide plate is irradiated on the display block for display. All the light guidebars are turned on by the flasher, and the light source connected to the light guide plate is transmitted to the light guide plate, so that all the anti-counterfeit identification codes on the lightguide plate are illuminated on the display block for display.

Description

technical field [0001] The invention relates to the field of information anti-counterfeiting, in particular to an anti-counterfeiting flasher. Background technique [0002] The anti-counterfeiting design of simple optical path inspection can be widely used in fields that can only be used once and require confidentiality or anti-counterfeiting. Before use, it can identify the authenticity of the object and whether it has been used. The used status can be used to reconfirm the authenticity of the product used. [0003] The anti-counterfeiting design of simple optical path inspection can be widely used in wine, cosmetics, password boxes and other high-end products that require anti-counterfeiting or occasions that require high confidentiality. Simple optical path inspection anti-counterfeiting products are simple to make, easy to inspect, and low in cost, suitable for large-scale and large-scale applications , but also can be specially made for special occasions.

Problems solved by technology

[0005] Nowadays, with the development of lamination technology and nanotechnology, the development of mold manufacturing technology and precision molding technology, combining the above technologies, it has become simple and feasible to realize the optical path inspection and anti-counterfeiting design products, and the improvement of counterfeiting, counterfeiting and cracking technology, Many traditional anti-counterfeiting technologies have become more and more unreliable, and the market expects more and more confidential anti-counterfeiting technologies to appear. At present, there are many anti-counterfeiting technologies on the market: such as electronic IC code reading anti-counterfeiting technology, laser anti-counterfeiting technology , mechanical non-recoverable anti-counterfeiting technology, etc., but the above technologies have technical defects, are easy to be cracked by interested people, and need to be updated frequently. After a period of time, the products before the update will not be able to distinguish the authenticity. To ensure that authentic products can be purchased in a short period of time after the new anti-counterfeiting design is updated, the operation is cumbersome and only raises the threshold for counterfeiting, but it cannot prevent counterfeiting by those who are interested

[0006] For example: electronic IC internal programming, code reader decryption and recognition technology has the advantages of unknowable internal information, anti-reverse programming and other advantages, it is very difficult to crack, but this technology relies on special code readers, it is difficult to popularize and promote, and it cannot be avoided The undamaged part of the IC is used repeatedly, and the code reader needs to be strictly controlled. Once it is lost, it is obtained by the counterfeiter, and the internal programming of the electronic IC is performed by itself, and it is read with a genuine code reader. What is read is considered anti-counterfeiting. It is difficult to identify the real ones. At this time, the use of IC internal programming technology will become an accomplice of counterfeiting, and the technical defects are obvious.

[0007] Another example: mechanical non-recoverable anti-counterfeiting technology, which uses a complex and fragile structure to prevent counterfeiting. It is easy to operate, does not rely on foreign objects, and has an intuitive and obvious effect. Once used, the complex and fragile structure is irreversibly damaged and cannot be reused. , the anti-counterfeiting effect is obvious, but because the complex and fragile structure adopted is a single entity structure, under the development of non-destructive flaw detection technology, the pure mechanical structure is easy to show mountains and dews under X-ray irradiation and CT imaging, exposing the true face, cannot Prevent counterfeiters from forging from the source of the packaging, technical defects are obvious
