As an important carrier of information interaction and identity verification, intelligent cards not only need to have efficient and stable functional modules, but also need to meet increasingly high market demands in terms of anti-counterfeiting security, optical display effect and energy efficiency. Especially in the payment field, consumers have direct and sensitive requirements for the anti-counterfeiting ability and visual effect of the card, and enterprises also need to rely on the personalized display of the card to enhance brand value. However, in the prior art, the design concept of traditional intelligent cards is relatively single, and the multi-dimensional requirements in actual use scenarios are not fully considered, resulting in obvious shortcomings in many aspects.

[0003] Although some cards in existing intelligent cards have tried to integrate light-emitting functions, most of the schemes use simple point light sources or single area light-emitting designs. This direct light penetration method cannot achieve uniform diffusion of light effects, and is prone to problems such as light spots and inconsistent brightness. For example, light may be too concentrated in the center area of the card, while the edge part is obviously dim. This not only affects the user's visual experience, but also limits the application scenarios of dynamic light effects in anti-counterfeiting and brand display, and cannot meet the requirements of enterprises for high-end customized display effects. In view of the above problems, the technical personnel in the field propose a light guide material and intelligent card combination to solve the above problems. UTILITY MODEL CONTENT

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1-3 The present invention provides an embodiment of a combination of a light guide material and a smart card, comprising a function card body 1, the function card body 1 comprising: a circuit board 101 disposed inside the function card body 1; a light guide layer 102 located above the circuit board 101 for diffusing light; a printed layer 103 located above the light guide layer 102 and containing a printed pattern 3; and a protective layer 104 covering the outermost layer of the function card body 1 for protecting internal components.

[0039] Specifically, the main body of the function card 1 is composed of a multi-layer structure, each layer having a specific function, which work together to realize the light effect display and data processing functions of the smart card.

[0040] Circuit board 101 is located inside the main body 1 of the function card, serving as the core support structure of the entire function card. Circuit board 101 is used to carry and connect functional modules, ensuring stable transmission of electrical signals. Through a reasonable layout design, circuit board 101 effectively reduces electrical interference while optimizing space utilization between components. Electrical connection lines 204 are also arranged on it to provide power and signal support to other layers and functional modules.

[0041] The light guide layer 102, made of flexible optical material and tightly bonded to the top of the circuit board 101, possesses highly efficient light diffusion capabilities. The surface of the light guide layer 102 features a microstructure texture, which adjusts the light propagation path to ensure uniform light distribution. The matte diffusion properties of the light guide layer 102 effectively reduce light spots, providing a soft light effect while maintaining uniform brightness across the entire card surface. An LED module 4 is embedded within the light guide layer 102 and electrically connected to the circuit board 101, ensuring an efficient combination of light source and light guide performance.

[0042] A printed layer 103, covering the light guide layer 102, is a functional layer containing a fixed pattern. The printed layer 103 is bonded to the light guide layer 102 using a special process, and the fixed pattern can present a dynamic optical effect under light. The pattern design of the printed layer 103 can be used for brand logos, anti-counterfeiting functions, or user-defined information. The light transmitted through the light guide layer 102 to this layer can form a bright and clear dynamic display effect.

[0043] The protective layer 104 is the outermost layer of the function card body 1, possessing excellent wear and aging resistance. It protects the internal light guide layer 102, printing layer 103, and circuit board 101 from external environmental influences. The protective layer 104 also prevents moisture and dust intrusion, ensuring the long-term stability and reliability of the function card. Its transparent or semi-transparent design not only does not affect the card's light performance but also provides additional mechanical strength.

[0044] Reference Figure 3 and Figure 5 The circuit board 101 is externally equipped with a functional module component 2, which includes: a control module 201 for controlling the working state of the light source and the functional chip 203; a radio frequency antenna power supply 202 for providing power to the entire system; a functional chip 203 for implementing identity authentication, data encryption and decryption, and access control functions; the functional chip 203 supports multiple function integrations, including identity authentication, payment, access control, and data storage, and can communicate with external devices through the control module 201 to complete function calls; and an electrical connection line 204 for connecting the above modules; the radio frequency antenna power supply 202 can obtain energy from the radio frequency field provided by the external terminal and provide a stable power supply to the functional chip 203 and the control module 201 through the electrical connection line 204.

[0045] Specifically, the functional module component 2 is located on the outside of the circuit board 101 and is the core electronic module collection of the function card. The functional module component 2 achieves efficient collaboration between modules through a compact design, while optimizing space utilization and signal transmission efficiency.

[0046] The control module 201, as the core control unit of the entire functional module component 2, coordinates the working states of the light source (including the LED module 4 inside the light guide layer 102) and the functional chip 203. The control module 201 can receive commands from external devices in real time and adjust the light effect mode and function call sequence according to the system's preset logic. Through the control module 201, the functional module component 2 achieves precise dynamic light effect display and data interaction with external devices. The control module 201 also has a built-in energy management function, which can automatically shut down some unnecessary modules after the system completes its tasks, reducing energy consumption and improving energy efficiency.

[0047] The RF antenna power supply 202 receives energy from the RF field of an external terminal (such as a POS machine or card reader), and converts the wireless RF signal into DC power through RF energy harvesting technology, providing a stable power output for the functional module component 2. The RF antenna power supply 202 distributes the power to the functional chip 203 and the control module 201 via electrical connection line 204. This design ensures the stability of power distribution in multi-tasking scenarios while simplifying the module power supply structure and adapting to various workload requirements.

[0048] Functional chip 203 is the core processing unit of functional module component 2, supporting multiple integrated functions, including identity authentication, payment, access control, and data storage. Functional chip 203 is connected to control module 201 and RF antenna power supply 202 via electrical connection line 204, enabling efficient data processing and transmission. Functional chip 203 incorporates multiple encryption algorithms to protect the security and privacy of user data. Functional chip 203 can also respond to function requests from external devices, authenticate, encrypt, and decrypt the requested data, and generate verification results. The verification results can be triggered by control module 201 to display the light effect feedback of LED module 4, indicating whether the operation was successful. Functional chip 203 has multi-tasking capabilities, enabling rapid completion of authentication, payment, and data storage operations, making it suitable for complex application scenarios.

[0049] Electrical connection line 204 connects control module 201, RF antenna power supply 202, and functional chip 203, providing a path for signal and power transmission. Its design utilizes highly conductive materials and optimized layout to effectively reduce energy loss during signal transmission, avoid interference between modules, and ensure the high efficiency and stability of system operation.

[0050] Reference Figures 3-5The light guide layer 102 contains an LED module 4, which provides a light source and works with the light guide layer 102 to achieve dynamic light effects. The light guide layer 102 is made of flexible optical material and has a frosted diffusion function to evenly distribute the light from the LED module 4. The printed layer 103 contains a fixed anti-counterfeiting pattern, which diffuses through the light guide layer 102 to form a dynamic light effect when the LED module 4 is lit. The LED module 4 includes multiple LED beads, supports multiple color temperatures and dynamic change modes, and adjusts brightness and color through the control module 201. The control module 201 can adjust the brightness and color through preset programs. The sequence control LED module 4 implements one or more of the following modes: monochromatic light constant light mode; multi-color light dynamic switching mode; designated area light source illumination mode. The surface of the light guide layer 102 has a microstructure texture to optimize the light diffusion angle, so that the light emitted by the LED module 4 is evenly distributed to the printing layer 103, while reducing light loss and improving the overall light efficiency performance. The printing layer 103 and the light guide layer 102 are combined through a physical bonding process to ensure that the light guide layer 102 can evenly propagate the light emitted by the LED module 4 to the printing layer 103, so that the printed pattern 3 forms a stable display effect.

[0051] Specifically, the light guide layer 102 is the core optical component of the function card, and the LED module 4 is embedded inside it. The light guide layer 102 is made of flexible optical material, which has good mechanical flexibility and can adapt to different design requirements of the function card. At the same time, the surface of the light guide layer 102 is designed with microstructure texture. This texture can optimize the propagation path of light and distribute the light emitted by the LED module 4 evenly across the entire surface of the light guide layer 102 at a specific diffusion angle.

[0052] LED module 4 is the light source unit in light guide layer 102, containing multiple high-efficiency LED beads, which can provide stable and high-brightness light source output. LED module 4 supports multiple color temperature changes and can achieve dynamic light effect switching through precise control algorithms, such as constant single-color light, dynamic switching of multi-color light, and light source illumination mode for designated areas. LED module 4 is connected to control module 201 through electrical connection line 204, and control module 201 manages its brightness, color, and dynamic switching mode.

[0053] In the monochromatic light constant-on mode, LED module 4 emits uniform monochromatic light, which is suitable for static display scenarios.

[0054] In the multi-color light dynamic switching mode, LED module 4 switches different colors of light source sequentially according to the preset program to form a flowing or gradual visual effect.

[0055] In the designated area light source illumination mode, the control module 201 controls the LED beads in a specific area to light up through precise address instructions, thereby achieving a regionalized light effect display.

[0056] The matte diffusion function of the light guide layer 102, combined with its microstructure texture design, effectively reduces the uneven intensity of light during propagation, preventing light spots. Simultaneously, this design also reduces light loss, improves overall luminous efficiency, and gives the entire surface of the light guide layer 102 a soft and uniform light effect. The integration of the LED module 4 with the light guide layer 102 achieves high-efficiency optical performance, with its light transmitted to the printed layer 103 through the diffusion effect of the light guide layer 102.

[0057] The printed layer 103 is disposed above the light guide layer 102 and is tightly bonded to the light guide layer 102 through a physical bonding process. This physical bonding process not only ensures the optical transmission efficiency between the two layers but also makes the structure more stable and less prone to separation or misalignment. The printed layer 103 contains a fixed anti-counterfeiting pattern, which can create a dynamic display effect when the LED module 4 is lit, through the uniformly diffused light from the light guide layer 102. Through dynamic light effects, the anti-counterfeiting pattern can exhibit different brightness or color changes, thereby enhancing its anti-counterfeiting performance.

[0058] The fixed anti-counterfeiting pattern on the printed layer 103, in conjunction with the light from the light guide layer 102, can not only create a high-contrast display effect but also display brand logos, identity authentication information, or user-defined content. Its dynamic display effect is particularly suitable for applications such as payment confirmation and identity verification prompts. For example, upon completion of payment, the anti-counterfeiting pattern on the printed layer 103 may flash a specific color to indicate successful operation; during identity verification, a specific area may light up to indicate successful authentication.

[0059] Working principle: First, the RF antenna power supply 202 provides power to the functional chip 203, control module 201 and LED module 4;

[0060] Secondly, the functional chip 203 communicates with external devices through the control module 201 to read the stored user identity data;

[0061] Then, the functional chip 203 verifies the external request and generates a verification result using the built-in encryption algorithm;

[0062] At the same time, the control module 201 triggers the light effect mode of the LED module 4 based on the verification results:

[0063] When verification is successful, a green light effect is activated, and confirmation information is dynamically displayed through the light guide layer 102 and the printing layer 103.

[0064] A red light effect illuminates when verification fails, indicating to the user that the operation has failed;

[0065] The functional chip 203 stores the authentication result and feeds it back to the external terminal via the electrical connection line 204.

[0066] Finally, after authentication is completed, the control module 201 shuts down some circuits and enters a low-power mode to extend the card's lifespan.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
