Description

Technical Field

[0001] This utility model relates to the field of light boxes, and in particular to a modular light box. Background Technology

[0002] In existing technologies, light boxes, as a common advertising display or signage device, are widely used in commercial venues, public transportation, road signs, and other fields. Their structure typically includes an outer frame, an internal light source assembly, and a translucent panel mounted on the surface of the outer frame. The desired text, patterns, or other content are projected onto the translucent panel, which emits light when illuminated by the internal light source, thus achieving a good visual recognition effect.

[0003] However, in practical use, existing modular light boxes have many inconveniences, especially in the replacement and maintenance of the light-transmitting panels. Currently, most light boxes use fixed connections between the light-transmitting panels and the frame, such as screw fastening, snap-fit, or adhesive bonding. If content needs to be changed or the panel is damaged, the entire modular light box often needs to be disassembled to complete the replacement. This structural design not only makes the maintenance process cumbersome and time-consuming, but also wastes materials and increases operating costs. Utility Model Content

[0004] The main purpose of this invention is to propose a modular lightbox that can retain other components when the light-transmitting panel is replaced, allowing these components to be recycled, thereby saving materials and reducing costs.

[0005] To achieve the above objectives, some embodiments of this utility model propose a modular lightbox, comprising:

[0006] The base has a mounting structure that is recessed in the vertical direction;

[0007] Support part, connecting base;

[0008] The light-transmitting panel is detachably connected to the mounting structure, and one side of the light-transmitting panel in the thickness direction is adapted to abut against the support.

[0009] In some embodiments, the base has a top panel with a through hole extending vertically through it, the through hole being configured as a mounting structure; and / or

[0010] The base has a recessed groove in the vertical direction, which is configured as a mounting structure.

[0011] In some embodiments, the through-hole is a horizontally extending strip, and the length of the through-hole is at least 1 mm longer than the length of the light-transmitting panel along the extending direction; and / or,

[0012] The light-transmitting panel includes a connector that is adapted to connect to a through hole.

[0013] In some embodiments, the support further includes a light-emitting component and a fixing panel, wherein the light-emitting component abuts against the side of the fixing panel opposite to the light-transmitting panel.

[0014] In some embodiments, the fixed panel is inserted into the mounting structure.

[0015] In some embodiments, the support also includes a light box back cover, the peripheral wall of which encloses an accommodating space for accommodating the light-emitting component. The light box back cover is connected to the side of the fixed panel opposite to the light-transmitting panel and is vertically spaced from the mounting structure.

[0016] In some embodiments, the back cover, the light-emitting component, and the fixing panel of the light box all have threaded holes. The modular light box includes threaded fasteners that pass through the threaded holes of the back cover, the light-emitting component, and the fixing panel in sequence to connect the back cover, the light-emitting component, and the fixing panel.

[0017] In some embodiments, the base has a receiving chamber, and the modular lightbox includes a power supply located in the receiving chamber and electrically connected to the light-emitting components.

[0018] In some embodiments, the base has a receiving chamber, and the light-transmitting panel extends into the receiving chamber through a mounting structure. The base includes a side wall panel and a partition plate, the partition plate being connected to the side of the side wall panel near the mounting structure and protruding from the side wall panel. The partition plate is capable of restricting the horizontal movement of the portion of the light-transmitting panel extending into the receiving chamber.

[0019] In some embodiments, the modular lightbox further includes a mirror assembly rotatably connected to the support portion. According to the above embodiments, the beneficial effects of this utility model are:

[0020] The modular lightbox of this invention includes a base, a support, and a light-transmitting panel. The base is designed with a vertically recessed mounting structure for mounting the light-transmitting panel. The support connects to the base, and its function is to provide a stable support point for the light-transmitting panel. That is, when the support and the base are relatively stably connected, the light-transmitting panel can rest against the support to prevent wobbling.

[0021] The light-transmitting panel is designed to be inserted into the mounting structure, with one side of its thickness contacting the support to ensure stability during use. The light-transmitting panel is detachably connected to the mounting structure for easy replacement, and the thickness side of the panel is adapted to abut the support, meaning the panel and support are separable. Therefore, replacing the panel will not affect the support. Compared to designs where the support and panel are bound together, this application allows for independent replacement of the light-transmitting panel, enabling the recycling of other components. This saves material on the support, improves material utilization, and reduces operating costs. For example, a lightbox panel may be divided into a fixed panel and a light-transmitting panel (such as a UV-printed panel). For instance, the original panel might be divided into a 3mm thick fixed panel and a 2mm thick light-transmitting panel. The 3mm thick fixed panel is fixed to the back cover of the lightbox with screws, while the 2mm thick light-transmitting panel is detachable, plug-and-play, and easy to replace. When changing the printed advertisement on the panel, this effectively saves the material cost of a 3mm thick fixed panel.

[0022] Furthermore, by inserting the light-transmitting panel into the mounting structure of the base and utilizing the support for lateral support, the entire modular lightbox can be quickly assembled and disassembled while ensuring stability. This design reduces the inconvenience of traditional fixing methods (such as screw fixing) and improves maintenance efficiency.

[0023] In summary, this design makes replacing the light-transmitting panel extremely convenient, requiring no complicated tools from the user. Furthermore, due to its detachable design, if a component malfunctions, only the affected part needs to be replaced, rather than the entire lightbox, thus saving materials and costs.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0048] The following is for reference. Figures 1 to 11 This describes a modular lightbox 10 according to an embodiment of the present invention. (Refer to...) Figures 1 to 7In some embodiments, the modular lightbox 10 includes a base 100, a support 200, and a light-transmitting panel 300. The base 100 has a vertically recessed mounting structure 111 for mounting the light-transmitting panel 300. The support 200 connects to the base 100, providing a stable support point for the light-transmitting panel 300. When the support 200 and the base 100 are relatively stably connected, the light-transmitting panel 300 can rest against the support 200 without wobbling. The support 200 can be detachably inserted into the mounting structure 111 of the base 100, or it can be fixed to the base 100 by threaded connections, welding, or other methods.

[0049] Reference Figures 8 to 10 The light-transmitting panel 300 is designed to be inserted into the mounting structure 111, with one side of its thickness direction contacting the support portion 200 to ensure stability during use. The light-transmitting panel 300 is detachably connected to the mounting structure 111 for easy replacement, and one side of the light-transmitting panel 300 in the thickness direction is adapted to abut against the support portion 200. Therefore, the light-transmitting panel 300 and the support portion 200 are separable, and replacing the light-transmitting panel 300 will not affect the support portion 200. Compared to a design where the support portion 200 and the light-transmitting panel 300 are bound together, this application allows for independent replacement of the light-transmitting panel 300, enabling the recycling of other components. This saves material on the support portion 200, improves material utilization, and reduces operating costs. For example, the lightbox panel is originally divided into a fixed panel 230 and a light-transmitting panel 300 (such as a UV-printed panel). For example, the original single panel is divided into two parts: a 3mm thick fixed panel 230 and a 2mm thick light-transmitting panel 300. The 3mm thick fixed panel 230 and the lightbox back cover 210 are fixed with screws, while the 2mm thick light-transmitting panel 300 is detachable, plug-and-play, and easy to replace. When changing the advertisement printed on the panel, it is equivalent to saving the material cost of a 3mm thick fixed panel 230.

[0050] Furthermore, by inserting the light-transmitting panel 300 into the mounting structure 111 of the base 100 and using the support 200 for lateral support, the entire modular light box 10 can be quickly assembled and disassembled while ensuring stability. This design reduces the inconvenience of traditional fixing methods (such as screw fixing) and improves maintenance efficiency.

[0051] In summary, this design makes replacing the light-transmitting panel 300 extremely convenient, requiring no complicated tools from the user. Furthermore, due to its detachable design, if a component malfunctions, only the affected part needs to be replaced, rather than the entire lightbox, thus saving materials and costs.

[0052] Understandably, in some embodiments, to further improve the stability of the light-transmitting panel 300, elastic clamping members can be added within the mounting structure 111 of the base 100. When the light-transmitting panel 300 is inserted, these clamping members will deform slightly, thereby generating a clamping force to ensure that the light-transmitting panel 300 will not easily loosen or fall off. For example, a metal sheet with memory function can be used as a clamping member, which can return to its original shape after being subjected to pressure, providing a continuous clamping force to the light-transmitting panel 300.

[0053] In some embodiments, considering the requirements of outdoor use environments, the materials of the base 100 and the support 200 can be adjusted, using more weather-resistant plastics or aluminum alloys. This not only helps resist the effects of harsh weather but also reduces the overall weight, making it easier to transport and install.

[0054] Reference Figures 4 to 7 In some embodiments, the support portion 200 further includes a light-emitting component 220 and a fixing panel 230. The light-emitting component 220 abuts against the side of the fixing panel 230 opposite to the light-transmitting panel 300, providing uniform illumination to the light-transmitting panel 300. Specifically, in some embodiments, the light-emitting component 220 includes a light strip 221, a reflector 222, and a light guide plate 223. The light guide plate 223 abuts against the side of the fixing panel 230 opposite to the light-transmitting panel 300, the reflector 222 abuts against the side of the light guide plate 223 opposite to the fixing panel 230, and the light strip 221 is circumferentially attached to the edge of the light guide plate 223. This design allows light to be emitted through the light-transmitting panel 300, forming a bright and uniform light source. The presence of the fixing panel 230 enhances the overall stability of the structure and provides a mounting platform for the light-emitting component 220. In some embodiments, the light-emitting component 220 includes multiple LED beads arranged on a plane to ensure that the emitted light covers the entire area of ​​the light-transmitting panel 300. The fixed panel 230 connects to the base 100 on one side and supports the light-emitting component 220 on the other, ensuring that all components fit together tightly and function in unison. Furthermore, thanks to the optimized layout of the light-emitting component 220 and the high-efficiency light-transmitting panel 300, the entire modular lightbox 10 provides more uniform and softer light, suitable for various interior decoration applications. In addition, the design of the fixed panel 230 simplifies the assembly process and reduces maintenance costs.

[0055] It is understood that in some embodiments, the light-emitting component 220 may use novel OLED technology instead of traditional LED beads. OLEDs have a thinner profile, higher luminous efficiency, and better color performance, which will greatly enhance the visual effect of the lightbox. For example, the OLED panel can be directly attached to the fixed panel 230 without the need for additional heat dissipation devices, simplifying the internal structure.

[0056] In some embodiments, a solar charging module is introduced as the energy source for the light-emitting component 220. This means that during the day, the solar panel can collect solar energy and convert it into electrical energy for storage, which can then be used by the light-emitting component 220 at night. For example, a small solar panel can be installed on top of the base 100, and the collection and distribution of electrical energy can be managed by an intelligent control system to achieve the goal of energy conservation and environmental protection.

[0057] Reference Figures 8 to 10 In some embodiments, the fixed panel 230 of the modular lightbox 10 is inserted into the mounting structure 111 of the base 100. This design primarily allows for easy insertion and removal of the light-transmitting panel 300, i.e., a detachable connection between the light-transmitting panel 300 and the base 100. In some embodiments, the light-transmitting panel 300 is held in place by means of snap-fit ​​or interlocking. This detachable design allows users to replace different types of light-emitting components 220 or adjust the light-emitting configuration as needed without completely disassembling the entire modular lightbox 10. Furthermore, this application employs a modular design, allowing any malfunctioning part to be replaced individually, avoiding resource waste. In addition, the ease of assembly and disassembly significantly reduces maintenance costs and time consumption.

[0058] It is understood that, in some embodiments, to further enhance the connection strength between the fixing panel 230 and the base 100, an elastic locking device can be provided on the edge of the fixing panel 230. For example, the two sides of the fixing panel 230 can be equipped with small latches with spring mechanisms. When the fixing panel 230 is inserted into the mounting structure 111 of the base 100, these latches will automatically pop out and lock in the corresponding positions to ensure a more secure connection.

[0059] In some embodiments, the material of the fixing panel 230 is changed to a weather-resistant material, such as stainless steel or engineering plastic, to improve the overall durability of the light box. For example, selecting materials with UV resistance and moisture-proof properties can effectively extend the service life of the fixing panel 230 and the components it supports.

[0060] Reference Figures 8 to 10In some embodiments, the support portion 200 further includes a light box back cover 210, the peripheral wall of which encloses a receiving space for accommodating the light-emitting component 220. The light box back cover 210 connects to the side of the fixing panel 230 opposite to the light-transmitting panel 300, and a certain gap is left between the light box back cover 210 and the mounting structure 111 in the vertical direction. This design not only protects the internal light-emitting component 220 from the influence of the external environment, but also provides additional space for heat dissipation management. The purpose of leaving a certain gap between the light box back cover 210 and the mounting structure 111 is that only the fixing panel 230 can be inserted into the mounting structure 111, while the light box back cover 210 cannot be inserted into the mounting structure 111. Since the back cover 210 of the light box houses the light-emitting component 220, and the structural rigidity of the back cover 210 is relatively weak compared to the fixed panel 230, if the back cover 210 of the light box is also configured to connect to the base 100, it is easy for the back cover 210 of the light box to be deformed under force, which not only damages the back cover 210 of the light box itself, but also easily damages the light-emitting component 220 in the housing space.

[0061] Furthermore, the back cover 210 of the light box creates a relatively independent working environment for the light-emitting component 220, reducing the impact of external dust, moisture, and other factors on the light-emitting component 220. In addition, the reserved gaps facilitate air circulation, further promoting heat dissipation and improving the reliability and stability of the system.

[0062] The design of the back cover 210 significantly improves the overall protection and heat dissipation efficiency of the modular lightbox 10. Especially in high-temperature environments, the excellent heat dissipation design effectively prevents overheating and ensures the normal operating life of the light-emitting components 220. At the same time, the enclosed design also enhances the safety of the lightbox and reduces the risk of accidental electric shock.

[0063] In some embodiments, the back cover 210 of the light box is made of a robust material, such as metal or high-strength plastic, to ensure that it can withstand a certain amount of physical pressure. The back cover 210 is tightly connected to the fixed panel 230 by threaded fasteners 400 or other suitable connection methods, forming a closed but easy-to-maintain system. Inside the back cover 210, the light-emitting components 220 are rationally arranged to facilitate effective heat dissipation.

[0064] It is understandable that, in some embodiments, a thermally conductive material layer can be added inside the back cover 210 of the light box to further optimize heat dissipation. For example, aluminum foil or graphene can be used as the thermally conductive material, which can effectively conduct the heat generated by the light-emitting component 220 to the surface of the back cover 210 of the light box, accelerating heat dissipation. Such a design is particularly suitable for application scenarios of high-power light-emitting components 220.

[0065] In some embodiments, the lightbox cover is detachably attached to the lightbox back panel, such as by a snap-fit ​​connection. This design makes the lightbox back cover 210 easy to replace, and its color, texture, and even shape can be customized to meet specific needs. For example, for specific commercial display purposes, a lightbox back cover 210 with brand logos or decorative patterns can be selected to enhance the overall visual effect without affecting its basic functionality.

[0066] Reference Figures 8 to 10 In some embodiments, the back cover 210, the light-emitting component 220, and the fixing panel 230 of the light box all have threaded holes. The modular light box 10 includes threaded fasteners 400, which pass sequentially through the threaded holes of the back cover 210, the light-emitting component 220, and the fixing panel 230 to connect them. This design ensures a tight fit and stability between the components, ensuring that they will not loosen even under vibration or temperature changes. It also provides a convenient disassembly and assembly method. When a component needs to be replaced or maintained, the operation can be easily completed by simply loosening the corresponding threaded fastener 400, without the need for extensive disassembly of the entire light box. Furthermore, this design facilitates transportation and installation, reducing logistics costs and on-site construction difficulties.

[0067] It is understood that in some embodiments, to further enhance the connection strength, reinforcing ribs may be added around the threaded hole or these areas may be manufactured using higher strength materials. For example, anti-loosening washers or spring washers may be used to prevent the threaded fastener 400 from loosening during long-term use.

[0068] In some embodiments, for outdoor applications, threaded fasteners 400 are manufactured using materials with stronger corrosion resistance. For example, using stainless steel screws instead of ordinary carbon steel screws can effectively extend the service life of the fasteners and reduce the frequency of maintenance due to environmental factors.

[0069] Reference Figures 4 to 7 as well as Figure 11In some embodiments, the base 100 has a top panel 110 with a through hole 1111 extending vertically through it, the through hole 1111 being configured as a mounting structure 111. In some embodiments, the base 100 has a recessed groove extending vertically, the groove being configured as a mounting structure 111. This design allows the light-transmitting panel 300 to be easily inserted or removed, achieving plug-and-play functionality and improving ease of use. The easy-to-replace design also preserves other structures when replacing the light-transmitting panel 300, thereby saving materials. Both the through hole 1111 and the recessed mounting structure 111 are designed to provide a stable and easy-to-operate interface, allowing the light-transmitting panel 300 to be positioned quickly and accurately. This design not only simplifies the assembly process but also reduces the potential risk of operational errors.

[0070] In some embodiments, the depth and width of the groove need to match the dimensions of the light-transmitting panel 300 to ensure good positioning and support. Furthermore, the edges of the groove are typically finely machined to make their surface smooth and burr-free, preventing scratches on the light-transmitting panel 300.

[0071] It is understood that, in some embodiments, in order to improve the durability of the mounting structure 111, a wear-resistant coating, such as a polytetrafluoroethylene (PTFE) coating, can be applied to the inner surface of the through hole 1111 or the groove. This not only reduces friction but also prevents wear problems caused by long-term use.

[0072] In some embodiments, the base 100 can be designed as a modular structure, allowing for flexible adjustment of the number and position of the mounting structures 111 according to actual application needs. For multi-faceted display scenarios, the base 100 can be equipped with multiple independent mounting structures 111 to facilitate the installation of light-transmitting panels 300 in different directions. For example, the base 100 can be designed in a cross-shaped or star-shaped layout, with a mounting structure 111 at the end of each branch, to meet diverse display requirements.

[0073] Reference Figures 4 to 6 In some embodiments, the through hole 1111 is designed as a horizontally extending strip, the length of which is at least 1 mm longer than the length of the light-transmitting panel 300. For example, the length of the through hole 1111 is 1 mm, 1.5 mm, or 2 mm longer than the light-transmitting panel 300, ensuring that the light-transmitting panel 300 can be smoothly inserted and removed. Specifically, the light-transmitting panel 300 is a regular plate, for example, the outline of the light-transmitting panel 300 is rectangular, and one section of the light-transmitting panel 300 is completely inserted into the through hole 1111.

[0074] In some embodiments, the diameter of the through-hole 1111 is smaller than the length of the light-transmitting panel 300. The light-transmitting panel 300 includes a specially designed insertion portion that matches the shape of the through-hole 1111. The insertion portion is used to insert into the through-hole 1111, allowing the light-transmitting panel 300 to be securely fixed to the base 100. Specifically, the insertion portion of the light-transmitting panel 300 is typically located on one side of the thickness direction of the light-transmitting panel 300 and has an appropriate size and shape to accommodate the design of the through-hole 1111. When the light-transmitting panel 300 is inserted into the through-hole 1111, the insertion portion fits tightly against the inner wall of the through-hole 1111, forming a mechanical locking effect to prevent the light-transmitting panel 300 from accidentally falling off. For example, the light-transmitting panel 300 can be in the form of a rectangular main body and several legs. The legs are used to insert into the through-hole 1111, and the main body is not used for connection. This design provides a clearer structural division, and the main body of the light-transmitting panel 300 is less susceptible to interference.

[0075] It is understood that, in some embodiments, to further enhance the securing effect of the light-transmitting panel 300, an anti-slip texture or coating may be added to the surface of the connector. For example, a connector made of rubber not only provides better friction but also reduces wear caused by frequent insertion and removal.

[0076] In some embodiments, an adjustable through-hole 1111 structure is designed. For example, the through-hole 1111 of the base 100 can be designed to be telescopic, allowing the size of the through-hole 1111 to be adjusted according to actual needs to accommodate light-transmitting panels 300 of different thicknesses. This can be achieved by providing spring mechanisms on both sides of the through-hole 1111, so that the through-hole 1111 can automatically adapt to the size changes of the light-transmitting panel 300 within a certain range.

[0077] Reference Figure 11 In some embodiments, the base 100 has a receiving chamber 120 for housing a power source. The power source is located within the receiving chamber 120 and is connected to the light-emitting component 220 via wires. This design isolates the power source from the external environment, providing better safety and protection. Simultaneously, since the power source is concealed within the base 100, the appearance is cleaner and more aesthetically pleasing, suitable for various application scenarios. Specifically, the receiving chamber 120 is typically formed by the side wall panels 130 and the bottom of the base 100, creating a closed space to protect the power source from external factors. The power source's input and output cables are connected to the light-emitting component 220 through pre-designed channels, ensuring a safe and reliable electrical connection. Furthermore, for ease of maintenance, the receiving chamber 120 can also be designed as an openable structure, such as a hinged door panel, facilitating user inspection and replacement of the power source.

[0078] It is understood that, in some embodiments, to further improve the efficiency of power management, an intelligent power management system can be integrated within the housing chamber 120. For example, an intelligent power controller with overload protection, short-circuit protection, and other functions can be used to monitor the power status in real time and automatically take corresponding measures to ensure the safe and stable operation of the system.

[0079] Understandably, in some embodiments, a backup power module is added. Especially in critical situations or emergencies, a backup power supply ensures the lightbox continues to operate, preventing display interruptions due to power failure. For example, a small battery pack can be designed as a backup power source, automatically switching to the backup power supply when the main power fails, maintaining the lightbox's basic lighting function. This dual-power design significantly improves system reliability and is suitable for mission-critical scenarios.

[0080] Reference Figure 11 In some embodiments, the base 100 includes a sidewall panel 130 and a partition plate 140. The partition plate 140 is connected to the sidewall panel 130 near the mounting structure 111 and protrudes a certain distance from the sidewall panel 130. This design allows the partition plate 140 to effectively restrict the horizontal movement of the portion of the light-transmitting panel 300 extending into the receiving chamber 120 when the light-transmitting panel 300 is inserted into the mounting structure 111, ensuring its positional stability. The partition plate 140 can be connected to the sidewall panel 130 by welding, screw fixing, or other mechanical connection methods. This design enhances the safety and stability of the light-transmitting panel 300. Through the limiting function of the partition plate 140, the position of the light-transmitting panel 300 can remain unchanged even in the event of changes in the external environment or accidental collisions, thereby extending its service life and reducing maintenance costs.

[0081] It is understood that, in some embodiments, to further improve the installation stability of the light-transmitting panel 300, an elastic cushioning material can be provided on the isolation plate 140. For example, rubber pads or foam strips can be attached to the contact surface of the isolation plate 140. This not only reduces the risk of damage from hard contact but also provides a certain cushioning effect to absorb vibration energy.

[0082] In some embodiments, an adjustable baffle plate 140 system is designed for light-transmitting panels 300 of different thicknesses. For example, the height or angle of the baffle plate 140 can be adjusted to accommodate light-transmitting panels 300 of various sizes. This can be achieved by providing slide rails and locking devices on the side wall panel 130, allowing the user to flexibly adjust the position of the baffle plate 140 according to actual needs.

[0083] Reference Figures 1 to 3In some embodiments, the modular lightbox 10 also includes a mirror assembly 500, which is rotatably connected to the support portion 200. The mirror assembly 500 is mainly used to enhance the reflection effect of light inside the lightbox, thereby improving the overall lighting brightness and uniformity. Specifically, the mirror assembly 500 typically consists of a mirror surface and a rotating shaft. One end of the rotating shaft is fixed to the support portion 200, and the other end is connected to the mirror surface, allowing the mirror assembly 500 to rotate freely within a certain range to adjust the reflection angle as needed. In addition, to facilitate the adjustment of the mirror angle, auxiliary devices such as a dial or positioning pin can be provided near the rotating shaft to help users precisely control the position of the mirror.

[0084] It is understood that, in some embodiments, multiple layers of coating can be added to the surface of the mirror assembly 500 to further optimize the light reflection effect. For example, using anti-reflective coating technology can significantly improve the reflectivity of the mirror to light of specific wavelengths, which is suitable for occasions where it is necessary to highlight certain color display effects.

[0085] In some embodiments, an intelligent control system is introduced to automatically adjust the angle of the mirror assembly 500. For example, by integrating sensors and a microprocessor, the system can monitor ambient lighting conditions in real time and automatically adjust the optimal reflection angle of the mirror to achieve the best lighting effect. This intelligent design is particularly suitable for dynamic display scenarios, such as shop windows or exhibition halls.

[0086] Below, refer to Figures 1 to 11 The modular lightbox 10 of this application is illustrated with a specific embodiment. For example, the modular lightbox 10 of this application includes a base 100, a support 200, a light-transmitting panel 300, and a mirror assembly 500. The support 200 includes a back cover 210, a light-emitting component 220, and a fixed panel 230. The light-emitting component 220 includes a light strip 221, a reflector 222, and a light guide plate 223. The back cover 210 is connected to the fixed panel 230 by screws. The back cover and the fixed panel 230 together enclose a receiving space for accommodating the light-emitting component 220. The upper panel 110 of the base 100 has a slot, which is configured as a mounting structure 111. Both the fixed panel 230 and the light-transmitting panel 300 are adapted to be inserted into the slot, thereby achieving a detachable connection with the base 100. The light-transmitting panel 300 can abut against the fixed panel 230, allowing the fixed panel 230 to provide support for it, thus ensuring the stability of the modular lightbox 10.

[0087] The assembly process of the modular lightbox 10 of this application is as follows: First, the light strip 221 is installed into the lightbox cover; then, the reflector 222 and the light guide plate 223 are installed into the back cover 210 of the lightbox in sequence; the fixing panel 230 is fixed to the back cover 210 of the lightbox with screws; then, the lightbox and the mirror assembly 500 are fixed together with hinges and screws; the assembled lightbox is inserted into the base 100; and then the light-transmitting panel 300 is inserted into the base 100. This design has a clear assembly logic and high operational efficiency in actual use. Furthermore, since the fixing panel 230, the light-transmitting panel, and the base 100 are all detachable, when one component needs to be replaced, the other components can be retained, thus saving materials.

[0088] In summary, the modular lightbox 10 of this application facilitates the replacement of parts, saves materials, and has low operating costs.
