Description

Technical Field

[0001] This application relates to the field of concealed light trough technology, and in particular to an embedded concealed light trough. Background Technology

[0002] A beverage display case is a commercial refrigeration device specifically designed for storing and displaying beverages. It is commonly found in supermarkets, convenience stores, restaurants, bars, cafes, and other places. Its core function is to maintain the freshness and taste of beverages through a low-temperature environment, while attracting customers' attention and promoting sales through transparent glass doors or open designs.

[0003] Currently, traditional beverage display cases typically use exposed lighting fixtures, such as LED tubes and bulbs directly installed on the top, sides, or edges of the shelves. These fixtures have significant drawbacks: firstly, the exposed fixtures are large, which disrupts the overall appearance and aesthetics of the cabinet and makes it difficult to integrate into the décor of high-end commercial spaces; secondly, the fixtures are exposed to the external environment and are prone to dust and moisture, which not only affects the lighting effect but also poses safety hazards such as short circuits and electrical leaks. Utility Model Content

[0004] To address the issue of exposed lighting fixtures, this application provides an embedded concealed light trough.

[0005] The embedded hidden light slot provided in this application adopts the following technical solution: An embedded concealed light trough includes a display cabinet with an outer shell inside. A sealing strip is provided along the edge of the outer shell to prevent dust and moisture from entering. A cover plate is provided on one side of the outer shell. An inner shell is provided inside the outer shell, and a thermally conductive silicone sheet is provided inside the inner shell. A light panel is provided inside the inner shell. A reflector for refracting light from the light panel is provided at the bottom of the outer shell. An auxiliary mechanism for adjusting the refraction angle of the reflector is provided at the bottom of the outer shell, and the reflector is located at the movable end of the auxiliary mechanism.

[0006] By adopting the above technical solution, the display cabinet serves as the installation carrier and final application scenario for the entire device. Its function is to provide structural support and installation space for the concealed light trough, and to accommodate the illuminated beverage products. The outer shell, as the main structure and first line of defense for the light trough, encapsulates all optical and mechanical components into an independent module, protecting internal components from physical impacts. Working with sealing strips, it provides basic dust and moisture protection. The core function of the sealing strips is to achieve a seal. The cover plate, as a side cover of the outer shell, facilitates installation and maintenance. By opening the cover plate, the internal light panels and wiring can be quickly inspected or replaced without disassembling the entire light trough system. The inner shell forms an independent internal cavity, isolating the light panels and their generated heat from the outer shell. Working with thermally conductive silicone pads, it establishes an efficient thermal management channel, while also providing auxiliary heat dissipation. The auxiliary mechanism provides the installation foundation. The core function of the thermally conductive silicone sheet is heat conduction. It can quickly conduct the heat generated by the LED light panel during operation to the inner shell, and then dissipate the heat to the external air or cabinet structure through the inner shell. This effectively prevents the LED from decaying due to overheating, ensuring light efficiency and extending its service life. The light panel is the light source of the device, emitting initial light to provide basic lighting for the beverage display. The reflector's function is to efficiently and evenly reflect the direct light emitted by the light panel and guide it to the beverages in the display case, achieving an indirect lighting effect of "seeing the light but not the lamp," improving visual comfort and the texture of the products. The auxiliary mechanism is the core actuator for dynamically adjusting the light angle. Its function is to precisely control the light reflection path by changing the spatial angle of its moving end (i.e., the reflector), thereby adapting to beverage displays at different heights and positions to achieve the best lighting effect. Preferably, there is a gap between the outer shell and the inner shell for air circulation, and a plurality of columns for guiding airflow are provided between the outer shell and the inner shell.

[0007] By adopting the above technical solution, the gap is a pre-reserved airflow channel between the outer shell and the inner shell. Its function is to form a heat dissipation channel for natural or forced convection, allowing hot and cold air to exchange here, thereby carrying away the heat absorbed by the inner shell from the lamp panel and improving the overall heat dissipation efficiency. The column serves as a structural support, fixing and maintaining the relative position and gap distance between the inner and outer shells. It also acts as a heat conduction bridge, assisting in the transfer of heat from the inner shell to the outer shell and increasing the heat dissipation area. Thirdly, it can guide and disturb the airflow, optimizing the heat dissipation effect.

[0008] Preferably, the housing has a rotating shaft inside, the cover plate is disposed on the outer surface of the rotating shaft, and the outer surface of the rotating shaft has a plurality of snap-fit ​​posts that are adapted to snap-fit ​​with the inside of the housing.

[0009] By adopting the above technical solution, the function of the pivot is to realize the hinge connection between the cover plate and the outer shell, so that the cover plate can rotate and open and close around the pivot like a door, which greatly facilitates the internal inspection and maintenance operations. The function of the snap-fit ​​post is to provide initial positioning and clamping force when the cover plate is closed, and work together with the plug-in structure to ensure the accuracy and stability of the cover plate installation.

[0010] Preferably, a plurality of plug-in pins are provided on one side of the cover plate, and a plurality of plug holes adapted to the plug-in pins are provided on the bottom side of one side of the outer shell, and the number of plug-in pins and plug holes is the same.

[0011] By adopting the above technical solution, the plug-in pin and socket provide a quick installation and precise positioning structure. When the cover is closed, the plug-in pin is precisely inserted into the corresponding socket. Its functions are twofold: first, to achieve precise positioning between the cover and the outer shell, preventing misalignment; and second, to form a multi-point mechanical locking mechanism, which, together with the rotating shaft and the snap-fit ​​pin, ensures the overall structural strength and sealing performance of the cover after it is closed.

[0012] Preferably, the auxiliary mechanism includes a support plate disposed at the bottom of the housing, and an arc-shaped column is disposed on the top surface of the support plate.

[0013] By adopting the above technical solution, the support plate serves as the mounting base for the entire angle adjustment mechanism, providing a stable and reliable fixing platform for subsequent components such as the arc column and motor. The arc column limits the rotation trajectory of the reflector, defining the rotation center and range of motion of the reflector's deflection motion, ensuring the stability and precision of the adjustment process.

[0014] Preferably, the outer surface of the arc-shaped column is symmetrically provided with arc-shaped plates, and the outer surface of the arc-shaped column is provided with an adjustment device.

[0015] By adopting the above technical solution, the function of the arc plate is to act as a transmission component, converting the rotational motion of the worm gear system into its own sliding along the surface of the arc column, thereby driving the auxiliary frame and reflector to deflect. The adjustment device is used to adjust the tilt angle of the reflector.

[0016] Preferably, the adjusting device includes a worm gear disposed on the outer surface of the arc-shaped column, an auxiliary frame disposed on the outer surface of the arc-shaped plate, one side of the auxiliary frame being fixedly connected to the reflector, and a worm gear meshing with the worm gear being disposed inside the auxiliary frame.

[0017] By adopting the above technical solution, the worm gear and worm are the core transmission and self-locking mechanisms. Their functions are twofold: first, to realize the conversion of motion mode, transforming the high-speed rotation of the motor into the low-speed, high-torque rotation of the worm gear, thereby achieving precise and stable angle adjustment of the reflector; second, to utilize the inherent self-locking characteristics of the worm gear transmission, when the motor stops, the angle of the reflector can be firmly locked and will not change due to vibration or gravity, ensuring the stability of the lighting effect. The auxiliary frame serves as a connecting and supporting component, fixing the reflector to it, while also housing and connecting transmission components such as the worm gear or arc plate, directly and rigidly transmitting the motion of the transmission mechanism to the reflector.

[0018] Preferably, a protective shell is provided on one side of the auxiliary frame, and a motor connected to the worm gear is fixed inside the protective shell.

[0019] By adopting the above technical solution, the motor is the power source of the entire regulating device. Its function is to provide rotational power according to control signals (such as remote control signals) to drive the worm gear to rotate. The protective shell provides a dedicated protective space for the motor and some transmission components. It can effectively isolate the motor from the influence of dust and moisture, and prevent accidental contact with moving parts during maintenance, thereby improving safety and reliability.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By fully embedding the light strip inside the display cabinet, a hidden light trough structure is created. After the light fixtures are installed, they are flush with or recessed into the cabinet surface, without affecting the overall lines of the cabinet, presenting a simple and smooth appearance. This allows it to easily blend into various high-end commercial scenarios and meet consumers' higher pursuit of the aesthetic value of display equipment.

[0021] 2. By using sealing strips along the edges of the outer casing, dust and moisture can be prevented from entering the interior. Simultaneously, the LED strip wiring is concealed within the display case's internal wiring channels, using waterproof and insulated wires and connectors to avoid safety hazards such as short circuits and electrical leaks caused by exposed wiring. Compared to traditional exposed lighting fixtures, which are susceptible to environmental factors leading to safety issues, the enclosed protective design and concealed wiring significantly improve the safety and stability of the display case lighting system, reduce the risk of equipment failure, and protect the safety of personnel and property in commercial spaces.

[0022] 3. By driving the worm gear to rotate via a motor, the worm gear moves along the surface of the worm wheel, which in turn causes the auxiliary frame and reflector to deflect. By adjusting the tilt angle of the reflector, the light emitted from the reflective light strip is adjusted, and the light is reflected onto the beverages in the display case. This ensures that every bottle of beverage from the front row to the back row receives uniform and full lighting, completely eliminating shadows and dark areas. This allows the color, texture, and brand logo of the beverage bottles to be presented in the most ideal state. Especially for glass bottled beverages, it creates a transparent and high-end visual experience, directly stimulating consumers' desire to buy. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0026] This application discloses an embedded hidden light trough.

[0027] Reference Figure 1 — Figure 3An embedded concealed light trough includes a display cabinet 1, with an outer shell 2 embedded in the inner wall of the display cabinet 1. A neodymium magnet array is embedded in the top surface of the outer shell 2, and steel sheets are attached to corresponding positions on the display cabinet 1 for quick positioning and disassembly. Sealing strips are provided along the edges of the outer shell 2 to prevent dust and moisture from entering. The outer shell 2 is made of ABS plastic or aluminum alloy, and its top surface has several micro-holes with a diameter of 0.5mm, providing both dust protection and ventilation. A cover plate 3 is hinged to the top of one side of the top surface of the outer shell 2. An inner shell 4 is fixedly connected to the bottom surface of the inner wall of the outer shell 2. Wiring holes are provided on one side of both the outer shell 2 and the inner shell 4. The top surface of the inner wall of the inner shell 4... A thermally conductive silicone sheet 5 is fixedly connected, and a light board 6 is snapped onto the inner wall of the inner shell 4, with the light board 6 in contact with the thermally conductive silicone sheet 5. The light board 6 can use dual-color temperature LED lights, such as 3000K warm light + 6000K cool light, and the color temperature can be switched by remote control. The wiring of the light board 6 is designed to be concealed, with the wiring embedded in the wire groove inside the display cabinet 1, and waterproof and insulated wires and connectors are used to avoid safety hazards such as short circuits and leakage caused by exposed wiring. A reflector 8 for refracting the light from the light board 6 is set at the bottom of the outer shell 2, and an auxiliary mechanism 7 for adjusting the refraction angle of the reflector 8 is set at the bottom of the outer shell 2, with the reflector 8 set at the moving end of the auxiliary mechanism 7.

[0028] By embedding the outer shell 2 into the display cabinet 1, a hidden light trough structure is created, presenting a simple and smooth appearance that can easily blend into various high-end commercial scenarios, meeting consumers' higher pursuit of the aesthetic value of display equipment. The sealing strips set on the edge of the outer shell 2 can prevent dust and moisture from entering the interior of the outer shell 2. At the same time, the wiring of the light panel 6 is designed to be hidden, with the light panel 6 embedded in the wire trough inside the display cabinet 1, and waterproof and insulated wires and connectors are used to avoid safety hazards such as short circuits and leakage caused by exposed wiring. Compared with traditional exposed lighting fixtures, which are easily affected by environmental factors and cause safety problems, the closed protection design and hidden wiring greatly improve the safety and stability of the cabinet lighting system, reduce the risk of equipment failure, and protect the safety of people and property in commercial places.

[0029] Reference Figure 3 — Figure 5The device consists of an outer shell 2 and an inner shell 4, forming a double-layered shell. The outer shell 2 is a dustproof and moisture-proof sealed structure, while the inner shell 4 is made of heat-dissipating aluminum profile. The interior of the inner shell 4 is serrated to increase the heat dissipation area, and there is a gap between the outer shell 2 and the inner shell 4 for air circulation. Several columns 21 are fixedly connected between the outer shell 2 and the inner shell 4, arranged in a linear array to form a longitudinal airflow channel. Natural convection is generated by utilizing the principle of hot air rising. A rotating shaft 33 is rotatably connected inside the outer shell 2, and a cover plate 3 is fixedly connected to the outer surface of the rotating shaft 33. A notch is opened on one side of the bottom of the cover plate 3, located away from the outer shell 2, for opening the cover plate 3. Furthermore, a sealing sponge strip is attached to the inner side of the cover plate 3 to ensure dust and moisture protection after closure. Several snap-fit ​​posts 34 are fixedly connected to the outer surface of the rotating shaft 33. The snap-fit ​​posts 34 are arranged in a circumferential array. The outer shell 2 has grooves that fit the snap-fit ​​posts 34. When the cover plate 3 rotates, the snap-fit ​​posts 34 can be engaged through the grooves to fix the cover plate 3. Several insertion posts 31 are fixedly connected to one side of the cover plate 3. The insertion posts 31 are arranged in a linear array and are located on the side close to the outer shell 2. Several insertion holes 32 are opened at the bottom of one side of the outer shell 2. The insertion holes 32 are arranged in a linear array. The insertion posts 31 and insertion holes 32 are matched for insertion. The number of insertion posts 31 and insertion holes 32 is the same.

[0030] During use, the serrated design of the inner wall of the inner shell 4 and the longitudinal guide groove designed between the outer shell 2 and the inner shell 4 utilize the principle of hot air rising to form natural convection, which can conduct the heat generated by the lamp panel 6 during use and discharge it through the micro-holes designed on the top surface of the outer shell 2 to ensure the heat dissipation of the lamp panel 6. In addition, when it is necessary to inspect the lamp panel 6, put your hand into the notch opened in the cover plate 3 and open the cover plate 3 outward to facilitate the inspection of the lamp panel 6 or cleaning of the inside.

[0031] Reference Figure 6 , Figure 7The auxiliary mechanism 7 includes a support plate 71 fixedly connected to the bottom of the outer casing 2. An arc-shaped column 72 is fixedly connected to the top surface of the support plate 71. Two arc-shaped plates 74 are fixedly connected to the arc surface of the arc-shaped column 72. The two arc-shaped plates 74 are symmetrically designed. An adjustment device is provided on the outer surface of the arc-shaped column 72. The adjustment device includes a worm gear 73 fixedly connected to the arc surface of the arc-shaped column 72. An auxiliary frame 76 is slidably connected to the outer surface of the arc-shaped plate 74. One side of the auxiliary frame 76 is fixedly connected to a reflector 8. The reflector 8 is located on the side away from the arc-shaped plate 74. A worm gear 75 is rotatably connected to the inner wall of the auxiliary frame 76, and the worm gear 75 meshes with the worm gear 73. A protective shell 78 is fixedly connected to one side of the auxiliary frame 76. A through hole is opened on the outer surface of the protective shell 78 for heat dissipation of the motor 77. The fixed end of the motor 77 is fixedly connected to the inner wall of the protective shell 78. The output end of the motor 77 is fixedly connected to the worm gear 75. The motor 77 can be controlled to rotate by a remote control.

[0032] When in use, to adjust the illumination angle of the light panel 6, press the button on the remote control to drive the motor 77 to rotate. When the motor 77 rotates, it drives the worm gear 75, which is fixedly connected to the motor 77, to rotate. Since the worm wheel 73 is fixedly set, when the worm gear 75 rotates, it will make a circular motion around the arc surface of the worm wheel 73. Since the worm gear 75 is connected inside the auxiliary frame 76, when the worm gear 75 makes a circular motion, it will drive the auxiliary frame 76 to deflect, which in turn drives the reflector 8, which is fixedly connected to the auxiliary frame 76, to deflect. This adjusts the illumination angle of the light, ensuring that every bottle of beverage from the front row to the back row receives uniform and full illumination, completely eliminating shadows and dark areas. This allows the color, texture, and brand logo of the beverage bottles to be presented in the most ideal state. Especially for glass bottled beverages, it can create a transparent and high-end visual experience, directly stimulating consumers' desire to buy.

[0033] The system controls the rotation of motor 77 and the color temperature switching of lamp panel 6 through a control system. The system uses a microcontroller as the control core, such as the common Arduino UnoATmega328P, ESP32 or STM32 series. It is responsible for receiving remote control commands and controlling the rotation of motor 77 and the color temperature switching of lamp panel 6. The system is driven by pressing the buttons on the remote control, such as: button "Up": motor 77 rotates forward and reflector 8 tilts upward. Button "Down": Motor 77 reverses, reflector 8 tilts down; Buttons "+" / "-": Adjust color temperature; Motor 77 is a servo motor, which can provide a smooth adjustment process and prevent the reflector 8 from becoming unstable due to vibration or weight changes.

[0034] The implementation principle of an embedded hidden light trough in this application embodiment is as follows: When in use, by embedding the outer shell 2 into the display cabinet 1, a hidden light trough structure is created, presenting a simple and smooth appearance. It can easily blend into various high-end commercial scenarios and meet consumers' higher pursuit of the aesthetic value of display equipment. With the sealing strip set on the edge of the outer shell 2, dust and moisture can be prevented from entering the interior of the outer shell 2. At the same time, the wiring of the light panel 6 is designed to be hidden. The light panel 6 is embedded in the wire trough inside the display cabinet 1, and waterproof and insulated wires and connectors are used to avoid the safety hazards such as short circuits and leakage caused by exposed wires. The color temperature of the light panel 6 can be adjusted by remote control so that the color, texture and brand logo of the beverage bottle can be presented in the most ideal state. When it is necessary to adjust the illumination angle of the light panel 6, the motor 77 is driven to rotate by pressing the button on the remote control. When the motor 77 rotates, it drives the worm gear 75, which is fixedly connected to the motor 77, to rotate, which in turn drives the reflector 8, which is fixedly connected to the auxiliary frame 76, to deflect. This adjusts the illumination angle, ensuring that every bottle of beverage from the front row to the back row receives uniform and full illumination, completely eliminating shadows and dark areas, creating a transparent and high-end visual experience, and directly stimulating consumers' desire to buy.
