Description

Technical Field

[0001] This utility model relates to the field of architectural decoration and lighting technology, and in particular to a luminous Lego wall. Background Technology

[0002] Currently, in the field of children's entertainment and creative display, LEGO walls are widely used in homes, educational institutions, and commercial spaces as a common building toy or decorative installation. However, traditional LEGO walls mainly rely on external light sources for illumination, which limits their display effect in low-light environments. To enhance visual appeal, some LEGO walls achieve a lighting effect by installing additional lighting fixtures, but this method requires complex wiring and power management, increasing the difficulty of installation and maintenance. Furthermore, the design of additional lighting fixtures often clashes with the overall style of the LEGO wall, potentially affecting its aesthetics. Simultaneously, because the positions of the lighting fixtures are fixed, it is difficult to flexibly adjust the illuminated area, resulting in some assembled works not achieving the desired display effect. These issues mean that existing LEGO walls still have room for improvement in terms of functionality and practicality. Utility Model Content

[0003] The purpose of this utility model is to provide a light-up Lego wall that solves the problems mentioned in the background art.

[0004] This invention is implemented as follows: a light-emitting Lego wall, mainly composed of a base plate, splicing modules mounted on the base plate, and a light guide component embedded in the splicing modules. The base plate is the main structure, and both the splicing modules and the light guide component are mounted on the base plate. The splicing modules are fixedly connected to the base plate via a snap-fit ​​structure, which includes elastic protrusions distributed at the bottom of the splicing modules and grooves on the surface of the base plate. The elastic protrusions and grooves cooperate to achieve quick installation and removal of the splicing modules. The light guide component is embedded inside the splicing modules and fits tightly against the side walls of the splicing modules. One end of the light guide component has a light source interface, and the other end extends to the outer surface of the splicing modules to form a light-emitting area.

[0005] The light guide assembly contains an optical fiber bundle. One end of the fiber bundle is connected to the light source interface, and the other end is evenly distributed on the outer surface of the splicing module. The fiber bundle transmits light from the light source interface to the outer surface of the splicing module through refraction and reflection. The fiber bundle is wrapped with a transparent protective layer made of polycarbonate to improve its durability and prevent light leakage. The light source interface contains metal contacts that contact the power supply terminals of the external power module to achieve power transmission. The external power module connects to the light source interface via a magnetic connection. The magnetic connector includes a magnetic ring inside the light source interface and a metal ring at the end of the external power module. The magnetic ring and the metal ring attract each other to complete the circuit connection.

[0006] The sidewall of the splicing module has a light-transmitting groove, the width of which matches the diameter of the fiber optic bundle. The fiber optic bundle is embedded in the groove and secured by a silicone gasket. The flexibility of the silicone gasket ensures the stability of the fiber optic bundle within the splicing module. The outer side of the light-transmitting groove is covered with a filter film, the color of which can be changed to achieve different color emission effects. The top of the splicing module has a connector hole, the shape of which matches the standard protrusions of LEGO bricks, allowing the splicing module to seamlessly connect with other LEGO bricks.

[0007] The back of the substrate has heat dissipation grooves, which are evenly distributed along the length of the substrate. The depth of the grooves is one-third of the substrate thickness, used to dissipate the heat generated during the operation of the light guide component. The inner wall of the heat dissipation grooves is coated with a graphite coating, which has good thermal conductivity and can further improve heat dissipation efficiency. The substrate has mounting holes around its four edges, and expansion bolts are embedded in the mounting holes. The expansion bolts are fixedly connected to the wall to achieve stable installation of the substrate.

[0008] The splicing module has a positioning post at its bottom. The positioning post is cylindrical and its height is slightly greater than the gap between the splicing module and the substrate. The positioning post is inserted into a positioning hole on the surface of the substrate to ensure that the splicing module is accurately positioned on the substrate. The inner wall of the positioning hole has anti-slip texture, which matches the outer surface of the positioning post to increase the friction between the splicing module and the substrate and prevent the splicing module from becoming loose.

[0009] This invention relates to a light-emitting LEGO wall, which solves the problem of limited display effects in low-light environments by combining a light guide component with a splicing module. The light guide component uses fiber optic bundles to evenly transmit light from the light source interface to the outer surface of the splicing module, achieving a light-emitting effect without the need for additional lighting fixtures. The magnetic connection method simplifies the connection process between the power module and the light source interface, avoiding complex wiring operations. The design of the light-transmitting groove and the filter film allows for flexible adjustment of the emitted color according to needs, enhancing the visual appeal of the LEGO wall. The combination of heat dissipation grooves and a graphite coating effectively reduces the temperature of the light guide component during operation, extending the lifespan of the device. The cooperation of the positioning posts and positioning holes ensures the precise installation of the splicing module on the substrate, improving the stability of the overall structure.

[0010] The luminous LEGO wall of this invention has a simple structure, low cost, and is suitable for large-scale production and application. Its modular design allows users to freely combine components according to their needs, greatly improving the functionality and practicality of the LEGO wall. Attached Figure Description

[0017] like Figures 1 to 3 As shown, this utility model discloses a light-emitting Lego wall comprising a base plate 1, splicing modules 2, and a light guide assembly 3. The base plate 1 serves as the main structure, with a flat mounting surface on its front for fixing the splicing modules 2. The splicing modules 2 are connected to the base plate 1 via a snap-fit ​​structure 4. The snap-fit ​​structure 4 consists of elastic protrusions distributed at the bottom of the splicing modules 2 and grooves on the surface of the base plate 1. The elastic protrusions are hemispherical structures made of a plastic material with a certain degree of elasticity, and their diameter is slightly larger than the opening width of the grooves on the surface of the base plate 1. When the splicing modules 2 are pressed onto the base plate 1, the elastic protrusions are compressed and deformed, embedding into the grooves. After the pressure is released, they return to their original shape, thereby achieving quick installation and disassembly of the splicing modules 2 and the base plate 1.

[0018] The splicing module 2 contains a light guide component 3, which is embedded and tightly fitted to the side wall of the splicing module 2. The light guide component 3 includes an optical fiber bundle 6, one end of which is connected to the light source interface 5, and the other end is evenly distributed on the outer surface of the splicing module 2, forming a light-emitting area. The optical fiber bundle 6 is wrapped with a transparent protective layer made of polycarbonate material with a thickness of 0.5mm, which effectively protects the optical fiber bundle 6 from external environmental influences and prevents light leakage. The light source interface 5 is located on one side of the splicing module 2 and contains metal contacts. These metal contacts contact the power supply terminals of the external power module to achieve power transmission. The external power module connects to the light source interface 5 via a magnetic connection. The magnetic connector includes a magnetic ring inside the light source interface 5 and a metal ring at the end of the external power module. The magnetic ring and the metal ring are attracted to each other to complete the circuit connection. The magnetic ring has a circular structure with an inner diameter matching the outer diameter of the metal ring. After attraction, the contact resistance between the two is less than 0.1 ohms, ensuring the stability of power transmission.

[0019] The side wall of the splicing module 2 is provided with a light-transmitting groove 7. The width of the light-transmitting groove 7 matches the diameter of the fiber optic bundle 6. The fiber optic bundle 6 is embedded in the light-transmitting groove 7 and fixed by a silicone gasket. The silicone gasket is 1mm thick, and its flexibility ensures the stability of the fiber optic bundle 6 within the splicing module 2, while preventing damage to the fiber optic bundle 6 due to movement of the splicing module 2. The outside of the light-transmitting groove 7 is covered with a filter film 8, which is attached to the surface of the light-transmitting groove 7 with double-sided adhesive. Different colored filter films 8 can be replaced as needed to achieve different light emission effects. For example, when a warm-toned atmosphere is required, an orange or red filter film 8 can be selected; when a cool-toned atmosphere is required, a blue or green filter film 8 can be selected.

[0020] The top of the assembly module 2 has a connector hole 9, which is a standard circular protrusion with a diameter of 4.8mm and a height of 1.6mm, exactly the same size as the standard protrusion of LEGO bricks. The inner wall of the connector hole 9 has anti-slip texture, which is a spiral structure, to increase the friction between the connector hole 9 and the LEGO bricks, ensuring a seamless connection between the assembly module 2 and other LEGO bricks. The bottom of the assembly module 2 has a positioning post 13, which is a cylindrical structure with a diameter of 3mm and a height of 2mm, slightly larger than the gap between the assembly module 2 and the base plate 1. The positioning post 13 is inserted into the positioning hole 14 on the surface of the base plate 1. The inner wall of the positioning hole 14 has anti-slip texture, which matches the outer surface of the positioning post 13, increasing the friction between the assembly module 2 and the base plate 1 and preventing the assembly module 2 from loosening. The cooperation between the positioning post 13 and the positioning hole 14 ensures that the assembly module 2 is accurately positioned on the base plate 1, improving the stability of the overall structure.

[0021] The back of the substrate 1 is provided with heat dissipation grooves 10, which are evenly distributed along the length of the substrate 1. Each heat dissipation groove 10 is 5mm wide and one-third the thickness of the substrate 1, i.e., about 3mm deep. The inner wall of the heat dissipation groove 10 is coated with a graphite coating 11 with a thickness of 0.2mm. The graphite coating 11 has good thermal conductivity and can quickly conduct the heat generated by the light guide component 3 during operation to the outside of the substrate 1, thereby reducing the overall temperature of the device. The substrate 1 has four mounting holes 12 around its four edges, located at the four corners of the substrate 1. Expansion bolts with a diameter of 6mm and a length of 50mm are embedded in the mounting holes 12. The expansion bolts are used to fix the substrate 1 to the wall, achieving a stable installation of the substrate 1.

[0022] In practical applications, the user first fixes the base plate 1 to the wall using expansion bolts, and then installs the splicing modules 2 one by one onto the base plate 1. The positioning pins 13 of the splicing module 2 are inserted into the positioning holes 14 on the surface of the base plate 1, and at the same time, the elastic protrusions of the snap-fit ​​structure 4 are embedded into the grooves on the surface of the base plate 1, completing the installation of the splicing module 2. Subsequently, the light guide assembly 3 is embedded inside the splicing module 2, so that one end of the fiber bundle 6 is connected to the light source interface 5, and the other end is evenly distributed on the outer surface of the splicing module 2. The external power module is connected to the light source interface 5 by magnetic attraction. After the magnetic ring and the metal ring are attracted, the circuit connection is completed. After the external power module is powered on, the metal contacts in the light source interface 5 transmit electrical energy to one end of the fiber bundle 6. The fiber bundle 6 transmits light to the outer surface of the splicing module 2 through refraction and reflection, forming a light-emitting effect.

[0023] Users can choose different colored light-filtering films 8 to cover the outside of the light-transmitting groove 7 to achieve different lighting effects. For example, in a children's room, a colorful light-filtering film 8 can be selected to create a lively atmosphere; in a meeting room, a white or light blue light-filtering film 8 can be selected to create a simple and bright environment. In addition, users can also freely combine the building blocks 2 as needed and connect them with other LEGO bricks using the interlocking holes 9 to build personalized LEGO wall patterns.

[0024] The heat dissipation grooves 10 and graphite coating 11 on the back of the substrate 1 can effectively dissipate the heat generated by the light guide component 3 during operation, preventing the device from being damaged due to overheating. During prolonged use, if the light emission effect of the splicing module 2 is found to be weakened, the user can check whether the connection between the light source interface 5 and the external power module is secure, and readjust the position of the magnetic connector if necessary. If the filter film 8 shows signs of aging or fading, the user only needs to peel it off from the outside of the light-transmitting groove 7 and replace it with a new filter film 8 to restore the original light emission effect.

[0025] The above embodiments detail the specific structure and assembly process of a light-emitting Lego wall according to this utility model. The substrate 1, splicing module 2, and light guide assembly 3, through a reasonable connection relationship and cooperation method, together constitute a fully functional and easy-to-operate light-emitting Lego wall. The material selection and structural design of each component have been rigorously considered to ensure the stability and durability of the device, while meeting the diverse needs of users for lighting effects.

[0026] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the actual operating principle of the luminous Lego wall is provided in conjunction with specific application scenarios.

[0027] First, the user needs to fix the base plate 1 to the wall using expansion bolts. The expansion bolts embedded in the mounting holes 12 have a diameter of 6mm and a length of 50mm, providing sufficient support when connected to the wall to ensure that the base plate 1 is firmly attached to the wall surface. Then, the user installs the splicing modules 2 one by one onto the surface of the base plate 1. During installation, the positioning pins 13 at the bottom of the splicing module 2 are inserted into the positioning holes 14 on the surface of the base plate 1. The height of the positioning pins 13 is slightly larger than the gap between the splicing module 2 and the base plate 1, thus increasing the friction between them through the anti-slip texture, thereby preventing the splicing module 2 from loosening. Simultaneously, the elastic protrusions in the snap-fit ​​structure 4 are embedded into the grooves on the surface of the base plate 1. The elastic protrusions are made of a plastic material with a certain degree of elasticity, and their diameter is slightly larger than the width of the groove opening. They deform under pressure during pressing and embed into the groove, returning to their original shape after the pressure is released, thus achieving quick installation and removal of the splicing module 2 and the base plate 1.

[0028] Next, the light guide component 3 is embedded inside the splicing module 2. One end of the fiber optic bundle 6 is connected to the light source interface 5, and the other end is evenly distributed on the outer surface of the splicing module 2, forming a light-emitting area. The fiber optic bundle 6 transmits light from the light source interface 5 to the outer surface of the splicing module 2 through refraction and reflection. The outer side of the fiber optic bundle 6 is wrapped with a 0.5mm thick transparent protective layer made of polycarbonate material, which effectively protects the fiber optic bundle 6 from the influence of the external environment and prevents light leakage. The external power module is connected to the light source interface 5 via a magnetic connection. The magnetic ring and the metal ring are attracted to each other to complete the circuit connection. The contact resistance is less than 0.1 ohms, ensuring the stability of power transmission. When the external power module is powered on, the metal contacts in the light source interface 5 transmit power to one end of the fiber optic bundle 6. The fiber optic bundle 6 transmits light to the outer surface of the splicing module 2 through refraction and reflection, thereby forming a light-emitting effect.

[0029] In practical applications, users can choose different colored light-filtering films 8 to cover the outside of the light-transmitting groove 7 to achieve different luminous effects. For example, in a children's room, users can choose colorful light-filtering films 8 to create a lively atmosphere; while in a conference room, white or light blue light-filtering films 8 can be chosen to create a simple and bright environment. The light-filtering film 8 is attached to the surface of the light-transmitting groove 7 with double-sided adhesive. When replacing it, simply peel it off and replace it with a new light-filtering film 8. In addition, users can freely combine the building modules 2 as needed, connecting them with other LEGO bricks using the interlocking holes 9 to build personalized LEGO wall patterns. The inner wall of the interlocking holes 9 has a spiral anti-slip texture, which increases the friction between the interlocking holes 9 and the LEGO bricks, ensuring a seamless connection between the building modules 2 and other LEGO bricks.

[0030] The heat dissipation grooves 10 on the back of the substrate 1 are evenly distributed along the length of the substrate 1. Each heat dissipation groove 10 is 5 mm wide and has a depth of one-third of the thickness of the substrate 1, approximately 3 mm. The inner wall of the heat dissipation groove 10 is coated with a graphite coating 11 with a thickness of 0.2 mm. The graphite coating 11 has good thermal conductivity and can quickly conduct the heat generated by the light guide component 3 during operation to the outside of the substrate 1, thereby reducing the overall temperature of the device. This design avoids damage caused by excessive temperature due to prolonged use.

[0031] If the light emission effect of the splicing module 2 weakens during prolonged use, the user can check whether the connection between the light source interface 5 and the external power module is secure, and readjust the position of the magnetic connector if necessary. If the filter film 8 shows signs of aging or fading, the user can simply peel it off from the outside of the light-transmitting groove 7 and replace it with a new filter film 8 to restore the original light emission effect.

[0032] The above steps detail the specific operation process and operating principle of this luminous Lego wall in practical applications. The rational design and coordination of each component ensures the stability and durability of the device, while also meeting users' diverse needs for luminous effects.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
