Description

Technical Field

[0001] This utility model relates to the field of signage technology, and in particular to a visually adjustable sign. Background Technology

[0002] In the existing product signage manufacturing field, such as car logos, brand logos, and safety warning signs, traditional processes such as chrome plating, etching, printing, or pasting are commonly used to represent patterns and text. These types of signs have the following drawbacks: 1. Traditional signs (such as chrome plating and etching) rely on complex processes, have long processing cycles, and high customization costs; 2. The signs cannot dynamically adjust brightness, color, or displayed content, resulting in poor environmental adaptability (e.g., low nighttime visibility); 3. Illuminated signs suffer from light spots and uneven brightness, with significant differences in visual effect when the viewing angle changes.

[0003] Taking the automotive industry as an example, traditional car logo design primarily relies on materials to construct the shape, then uses additional processes (such as chrome plating) to create variations in brightness or color to form the pattern. It lacks inherent light-emitting capabilities, resulting in poor brand recognition and limited design freedom. Furthermore, the brightness of the bright areas created by chrome plating is highly uneven. Observing the chrome-plated areas of the logo from different angles, and even observing different chrome-plated areas from the same angle, reveals significant differences in brightness, making the pattern appear uneven, with unclear boundaries between light and dark, and insufficient logo recognition. Even simply adding a light-emitting function to the logo results in uneven light emission due to the characteristics of light source projection. Observing the same area from different angles, or different areas from the same angle, will reveal inconsistent brightness, which not only affects aesthetics but may even lead to misidentification. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a visually adjustable sign that solves the technical problems of existing signs, such as complex process, high cost, poor environmental adaptability, and insufficient brightness and uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A visually adjustable label includes: a base layer; a light source layer disposed on the upper surface of the base layer, including a light source and a light guide plate, wherein the light guide plate is provided with microstructures; a light transmission adjustment layer disposed on the upper surface of the light source layer, composed of an electrochromic material or a liquid crystal material; a protective layer disposed on the upper surface of the light transmission adjustment layer; and a control module electrically connected to the light source layer and the light transmission adjustment layer, used to regulate the light emission state of the light source layer and the light transmission state of the light transmission adjustment layer.

[0007] This invention achieves dynamic adjustment of the brightness, color, and display mode of the markers through the coordinated control of the light source layer and the light transmission adjustment layer by the control module, significantly improving the visibility under different lighting conditions. Simultaneously, the microstructured light guide plate effectively eliminates light spot phenomena, ensuring a uniform visual effect from different viewing angles. Furthermore, it simplifies the manufacturing process and reduces production costs.

[0008] Optionally, the light source layer and the substrate layer are fixed together by mechanical connectors or adhesives.

[0009] Optionally, the light source is a distributed LED disposed on the side of the light guide plate, and the microstructure is a dot matrix and / or a prism. Using a distributed LED array in conjunction with a light guide plate having a microprism structure effectively eliminates light spot phenomena and ensures a uniform visual effect from different viewing angles.

[0010] Optionally, the light transmission adjustment layer is bonded to the light guide plate using optical adhesive.

[0011] Optionally, the protective layer is bonded to the upper surface of the light-transmitting adjustment layer using optical adhesive.

[0012] The protective layer effectively prevents the light-adjusting layer and the light source layer from being scratched, contaminated, or exposed to moisture, thus extending the lifespan of the sign and ensuring its long-term stable operation even in complex environments. The use of optical adhesive bonding eliminates air gaps between layers, reducing light reflection and refraction losses at the interfaces. This not only improves light extraction efficiency but also further ensures the uniformity of light output, resulting in a clearer and more refined display.

[0013] Optionally, the control module integrates an environmental sensing device, which includes a light sensor and / or a temperature sensor; the control module is configured to automatically adjust the output of the light source layer based on the detection data from the environmental sensing device. Environmental perception and adaptive adjustment facilitate intelligent management of the indicator brightness.

[0014] Optionally, the sign also includes a wireless communication module electrically connected to the control module, used to receive external commands via Bluetooth or Wi-Fi. This adds remote wireless control and content update capabilities, allowing users to change the sign's display content, mode, or on / off status without physical contact, greatly improving ease of use and flexibility, and reducing the cost of later maintenance and updates.

[0015] Optionally, the sign also includes an energy harvesting unit and an energy storage unit; the energy harvesting unit is a solar-powered unit and / or a wireless charging unit; the energy storage unit is electrically connected to the energy harvesting unit, used to store electrical energy, and to power the control module, the light source layer, and the light transmission adjustment layer. Compactly integrating the control, energy storage, and energy harvesting units results in a compact structure, and the modular design also helps reduce costs and the sign's size. The top-mounted solar panel maximizes sunlight reception, improving charging efficiency, and solar charging prevents the sign from becoming unusable after a power outage.

[0016] Optionally, the control module and energy storage unit are mounted on one side of the base layer via a mounting shell; when the energy harvesting unit is a solar power supply unit, its solar panel is mounted on the top of the mounting shell via a bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model adopts a modular layered design to replace the traditional complex processes such as chrome plating and etching, which simplifies the processing flow, shortens the production cycle, and reduces production costs.

[0019] 2. By controlling the light source layer and the light transmission adjustment layer in a coordinated manner through the control module, the brightness, color and display mode of the markings are dynamically adjusted, which significantly improves the recognizability under different lighting conditions.

[0020] 3. The use of a distributed LED array in conjunction with a light guide plate with a microprism structure effectively eliminates light spot phenomenon and ensures a uniform visual effect from different viewing angles.

[0021] 4. By integrating an energy harvesting unit and an energy storage unit, it supports solar power supply and wireless charging. Compared with traditional luminous signs that rely on external power, fail when power is off, and lack intelligent energy-saving control, this utility model enables continuous operation after power failure, improves the product's environmental adaptability and reliability, and can achieve intelligent energy-saving control.

[0022] 5. Through environmental sensors and wireless communication modules, automatic brightness adjustment and remote content updates of the signs are achieved, improving the product's intelligence and ease of maintenance. Attached Figure Description

[0033] The following disclosure provides many different implementations or examples for carrying out different structures of the embodiments of this utility model application. To simplify the disclosure of the embodiments of this utility model application, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the embodiments of this utility model application.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, this utility model application provides a visual adjustment mark, including: a base layer 1, a light source layer 2, a light transmission adjustment layer 3, a protective layer 4, and a control module 5.

[0036] The base layer 1 provides support and fixation for the other layers, forming the foundation of the entire layered structure. The light source layer 2 is located on the upper surface of the base layer 1, providing the light required for the signage. The light transmission adjustment layer 3 is located on the upper surface of the light source layer 2, adjusting the light transmittance and scattering effect. The protective layer 4 is located on the upper surface of the light transmission adjustment layer 3, protecting the light transmission adjustment layer and the light source layer from external environmental influences and damage. The control module 5 is electrically connected to the light source layer 2 and the light transmission adjustment layer 3, controlling the light emission state of the light source layer 2 and the light transmission state of the light transmission adjustment layer 3. Specifically, the control module 5 can adjust the brightness, color, and refractive index of the light source and the light transmission layer, enabling dynamic display of the signage (such as gradient, flashing, and pattern switching). This invention overcomes the shortcomings of traditional signage, which is limited by its single form and inability to dynamically change, by adding a controllable light transmission adjustment layer and coordinating it with the light source layer. It achieves dynamic controllability of the signage pattern, brightness, and color, effectively improving the signage's recognizability.

[0037] When designing the substrate layer 1, factors such as its strength, stability, and corrosion resistance need to be considered. Regarding material selection, depending on the specific application scenario and requirements, the materials used for the substrate layer 1 include, but are not limited to, metals, plastics, and ceramics. Furthermore, the surface of the substrate layer 1 needs to be smoothed to ensure that the light source layer 2 can be firmly fixed to it.

[0038] Optionally, a heat dissipation structure is provided on the base layer 1 to help dissipate heat from the light source layer 2, thereby improving its service life and performance.

[0039] In one embodiment, the light source layer 2 includes a light source and a light guide plate, and the light guide plate is provided with microstructures.

[0040] Optionally, the light source is a distributed LED located on the side of the light guide plate, and the microstructure is a dot matrix and / or prisms. The light source layer 2, by using a microstructured light guide plate in conjunction with the distributed LED light source, helps to eliminate light spots and ensure consistent brightness across multiple viewing angles.

[0041] In other embodiments, the light source can be selected from existing LED lamps, fluorescent lamps, or other different types of light sources. The appropriate light source color, brightness, and emission angle can be chosen according to different application scenarios and requirements. Preferably, the light source layer 2 includes a distributed LED array and a light guide plate. Uniform light emission can be achieved by providing a microprism structure on the surface of the light guide plate. The distributed LED light source and microstructure array used in the light source are existing technologies and are therefore not shown in the figure.

[0042] Optionally, the light source layer 2 and the substrate layer 1 can be fixed together by mechanical connection or adhesive bonding. During the connection process, it is necessary to ensure a good electrical connection between the light source layer 2 and the substrate layer 1 to avoid problems such as poor contact. For example, the light source layer 2 and the substrate layer 1 are fixed together by adhesive bonding or screws, ensuring that the connection between the light source layer and the substrate layer is firm and reliable.

[0043] In one embodiment, the light transmittance adjustment layer 3 is composed of an electrochromic material or a liquid crystal material. The liquid crystal material or electrochromic material can adjust the light transmittance and scattering effect by controlling parameters such as voltage and current.

[0044] Optionally, the light transmission adjustment layer 3 and the light guide plate of the light source layer 2 can be bonded together using optical adhesive. Optical adhesive has good light transmittance and adhesion, ensuring a tight bond between the light transmission adjustment layer 3 and the light guide plate without affecting light propagation. During assembly, the light transmission adjustment layer needs to be bonded to the upper surface of the light guide plate of the light source layer. During the bonding process, it is necessary to ensure a tight bond between the light transmission adjustment layer and the light guide plate to avoid air bubbles and gaps that could affect light propagation and adjustment effects.

[0045] Optionally, the protective layer 4 is bonded to the upper surface of the light-transmitting layer 3 using optical adhesive. During the bonding process, it is necessary to ensure a tight bond between the protective layer 4 and the light-transmitting layer 3, avoiding the formation of bubbles, impurities, and gaps, thus ensuring the light transmittance and protective effect of the protective layer 4 and preventing any impact on light propagation and protection. The protective layer 4 is made of a material with good wear resistance, corrosion resistance, and light transmittance. For example, the materials used for the protective layer 4 include, but are not limited to, glass and plastic.

[0046] In one embodiment, the control module 5 integrates an environmental sensing device, including a light sensor and / or a temperature sensor. This device automatically adapts to changes in ambient light intensity or temperature, and uses a dynamic compensation algorithm to adjust the light source output in real time based on sensor feedback, compensating for viewing angle or environmental interference. In other words, the control module 5 is configured to automatically adjust the output of the light source layer based on the detection data from the environmental sensing device. Through environmental perception and adaptive adjustment, intelligent management of the marker brightness is achieved.

[0047] In one embodiment, a wireless communication module is also included. The wireless communication module is electrically connected to the control module 5 and is used to receive external commands via Bluetooth or Wi-Fi to achieve remote control or content updates.

[0048] In one embodiment, the system further includes an energy harvesting unit and an energy storage unit 6. The energy harvesting unit is a solar-powered unit and / or a wireless charging unit; the energy storage unit 6 is electrically connected to the energy harvesting unit, used to store electrical energy, and to power the control module 5, the light source layer 2, and the light transmission adjustment layer 3. The built-in energy storage unit ensures continuous operation after a power outage.

[0049] Optionally, the control module 5 and the energy storage unit 6 are mounted on one side of the base layer 1 via a mounting shell 7; when the energy harvesting unit is a solar-powered unit, such as Figure 3 As shown, the solar panel 8 is mounted on top of the mounting housing 7 via a bracket, which can be connected to the top or to the rear side of the base layer. In some embodiments, the base layer, light source layer, light transmission adjustment layer, and protective layer can also be embedded in a single housing.

[0050] Optionally, the label may also include a display panel that is electrically connected to the control module. The display panel can be used to display operating status, alarms, etc., and can be embedded in the front of the mounting shell next to the protective layer.

[0051] Optionally, a telescopic structure can also be installed at the bottom of the sign. The telescopic structure is not shown in the diagram. Using existing technology, the installation position of the sign can be adjusted by the telescopic structure according to different usage scenarios, making it convenient to use.

[0052] In practical applications, the light source layer and the light transmission adjustment layer adopt standardized interfaces, which facilitates rapid replacement or upgrades. Specifically, the connection between the light source layer and the light transmission adjustment layer needs to balance the convenience of physical fixation, efficient transmission of optical signals, and stable electrical / signal interaction. The physical connection interface features a tool-free, quick-disassembly design; the optical connection interface uses a low-loss optical coupling design; and the electrical and signal interfaces employ modular contact connections. The embedded control module establishes stable connections with both the LED light source layer and the light transmission adjustment layer through layered independent drives and standardized electrical interfaces. The connection to the LED light source layer can use a driver circuit interface, while the connection to the light transmission adjustment layer can use an analog signal drive interface. Compared to traditional signs that require complete replacement after damage, this invention allows for individual replacement, reducing maintenance costs.

They do not involve the limitation of the specific position and size in the actual embodiment.

[0054] Any aspects not described in detail in this embodiment are techniques known in the art.

[0055] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
