Description

Technical Field

[0001] This utility model relates to the field of furniture lighting technology, and in particular to a light-emitting structure with invisible light effect. Background Technology

[0002] Currently, gaming desks with integrated lighting effects are becoming increasingly popular to enhance product aesthetics and technological appeal. The desk legs, as crucial visual supports, are key components in achieving these lighting effects. However, existing gaming desk lighting structures generally suffer from multiple technical bottlenecks.

[0003] In terms of structural adaptability, traditional LED light strips mostly use rigid circuit boards as the substrate, which greatly limits their bending radius and ductility, making it impossible to closely fit the complex irregular inner walls of curved table legs for lighting. This results in lighting designs being limited to straight lines or simple arcs, with low design freedom. More importantly, as height-adjustable furniture, gaming desks experience mechanical deformation and stress on their legs during frequent raising and lowering. Under these conditions, rigid light strips are highly susceptible to breakage, solder joint detachment, and other malfunctions due to repeated bending, seriously affecting product lifespan and reliability.

[0004] In terms of optical processing, conventional solutions often use ordinary acrylic panels directly covering the LED light source, which has significant drawbacks. When the device is off and not emitting light, the LED beads behind the panel are faintly visible, forming a messy array of light spots, severely damaging the overall appearance and high-end feel of the table. When the device is lit, due to the lack of effective optical shielding and light-diffusing mechanisms, the light shines directly and intensely from the gaps between the LED beads, resulting in severe "light spots" and "halos," producing a harsh and uneven light effect and a cheap visual appearance.

[0005] To address the issues of uniform lighting and concealing the internal structure, a prior patent (application number 2025216427903) proposed adding a ring-shaped light-shielding plate between the light source and the outer panel. The central light-transmitting area allows for directional light emission, while the surrounding opaque portion shields the rear light source and wiring. While this solution improves the visual appearance to some extent, the positioning and fixing of the light-shielding plate typically relies entirely on manual alignment and adhesive application by the operator. This assembly method is inefficient and makes it difficult to guarantee the relative positional accuracy between the light-shielding plate and the frame. It is highly susceptible to tilting, misalignment, or adhesive contamination of the light-transmitting area during installation, resulting in uneven lighting, edge light leakage, or visual defects. This still fails to meet the stringent quality and aesthetic requirements of high-end gaming furniture.

[0006] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0007] To address the aforementioned problems, the purpose of this invention is to provide a light-emitting structure with invisible light effects, which has the advantages of improving installation accuracy, preventing light leakage, and enhancing structural reliability.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] This application provides a light-emitting structure with a stealth light effect, the technical solution of which is as follows: an annular frame, the middle of which encloses a cavity and has an opening on at least one side; the annular frame has a slot on the inner wall of the cavity opening; an annular light-shielding sheet has an insert plate on its edge, the insert plate being inserted into the slot to achieve the initial positioning of the annular light-shielding sheet in the cavity, and the annular light-shielding sheet being fixedly connected to the annular frame after positioning; a panel is fixedly installed on the outside of the annular light-shielding sheet; a flexible light strip is disposed on the inner wall of the cavity; wherein, the light emitted by the flexible light strip passes sequentially through the central light-transmitting area of ​​the annular light-shielding sheet and the panel, and is projected outward to form a light effect.

[0010] Furthermore, this application also proposes that the distance between the annular light-shielding plate and the cavity opening is substantially the same as the thickness of the panel, so that the outer surface of the panel is substantially flush with the end face of the annular frame.

[0011] Furthermore, this application proposes that the flexible light strip is a COB flexible light strip and is arranged along the curved surface of the inner wall of the chamber. Furthermore, this application proposes that the COB flexible light strip is fixed by one of the following methods: a) directly attached to the inner wall of the chamber; b) embedded in a groove opened in the inner wall of the chamber.

[0012] Furthermore, this application also proposes that the panel is an acrylic double-sided mirror, which reflects external light and blocks the interior of the cavity when the flexible light strip is not emitting light.

[0013] Furthermore, this application proposes that the edge of the panel be fixed to the outer side of the annular light-shielding sheet by adhesive. Furthermore, this application also proposes that each inner wall of the annular frame is provided with a slot, and each outer wall of the annular light-shielding sheet is provided with an insert plate.

[0014] Furthermore, this application also proposes that after the insert plate is inserted into the slot to achieve initial positioning, the annular light-shielding plate and the annular frame are fixed together by welding.

[0015] Furthermore, this application also proposes that the ring frame is a polygonal frame, which is formed by welding multiple pipes together.

[0016] Furthermore, this application also proposes that the annular frame has chamber openings on both the front and rear sides of the chamber, and that at least one chamber opening is provided with an annular light-shielding plate and a panel.

[0017] As can be seen from the above, the light-emitting structure with invisible light effect provided by this application achieves precise positioning of the ring-shaped light-shielding sheet through the plug-in cooperation of the slot and the plate. Combined with the flexible light strip arranged along the curved surface and the double-sided mirror characteristics of the panel, it solves the problems of large installation deviation, light leakage and easy damage of rigid light strips in traditional structures. It has the advantages of improving installation accuracy, avoiding light leakage and improving structural reliability. Attached Figure Description

[0027] In existing technologies, the legs of gaming desks, as key components for lighting decoration, generally face technical bottlenecks in terms of structural adaptability and optical processing. Traditional LED light strips use rigid circuit boards, which have limited bending radius and ductility, making them unable to conform to the irregular inner walls of curved desk legs. This results in limited lighting designs and susceptibility to damage from frequent bending. Conventional optical solutions use ordinary acrylic panels to directly cover the light source, leaving the LED beads visible when not emitting light and exhibiting light spots and halos when emitting light. Existing patented solutions improve the appearance with ring-shaped light shields, but these rely on manual alignment and adhesive application, which carries the risk of positioning errors and adhesive contamination, leading to uneven light effects.

[0028] To address the aforementioned issues, the inventors discovered that the inability of rigid LED strips to adapt to curved surfaces is the root cause of breakage and limited placement, while positioning errors of the light-shielding plate directly affect the uniformity of light efficacy. By analyzing the impact of mechanical deformation on the LED strip, they proposed using flexible materials to replace the rigid substrate, allowing it to conform to complex curved surfaces and withstand dynamic stress. Regarding the positioning problem of the light-shielding plate, they found that an interlocking structure can achieve rapid and accurate alignment, avoiding errors from manual operation. Furthermore, by combining the layered design of the reflective panel and the light-shielding plate, a dual optical control is formed, eliminating internal visibility in the non-emitting state.

[0029] like Figure 1-4As shown, this application proposes a light-emitting structure with invisible light effect, including an annular frame 1, the middle of which encloses a cavity 4 and at least one side forms a cavity opening 3, the inner wall of the cavity opening 3 is provided with a slot 2; the edge of the annular light shield 7 is provided with an insert plate 8, the insert plate 8 is inserted into the slot 2 to achieve initial positioning, and after positioning, it is fixedly connected to the annular frame 1; the panel 5 is fixedly installed on the outside of the annular light shield 7; the flexible light strip 6 is disposed on the inner wall of the cavity 4; the light from the flexible light strip 6 passes through the central light-transmitting area 71 of the annular light shield 7 and the panel 5 in sequence and is projected outward to form a light effect.

[0030] The annular frame 1 can be a polygonal structure formed by welding multiple pipes. The central cavity 4 is used to accommodate the light strip and the light shield, and the cavity opening 3 provides installation space for the panel 5 and the light shield. The slot 2 refers to a groove structure formed on the inner wall of the cavity opening 3, which can be machined to guide the insertion plate 8 and limit the displacement of the light shield. The annular light shield 7 is a sheet-like component with a central light-transmitting area 71. The light-transmitting area can be circular or polygonal in shape, and the surrounding area is made of opaque material to block light scattering. The insertion plate 8 is a protruding structure extending from the edge of the light shield, with dimensions matching the slot 2, forming a mechanical limit after insertion. The panel 5 is a light-transmitting panel, which is fixed to the outside of the light shield by adhesive. The flexible light strip 6 is a bendable light source that can be attached to the inner wall of the curved surface or embedded in the groove to adapt to dynamic deformation.

[0031] Specifically, the annular frame 1 forms a stable cavity structure through welding. The slot 2 and the insert plate 8 work together to quickly position the light-shielding sheet to the preset position, avoiding deviations caused by manual adjustment. After the light-shielding sheet is fixed, it is firmly connected to the frame 1, such as by welding as described below, ensuring structural stability. The panel 5 covers the outside of the light-shielding sheet, forming a smooth surface. The flexible light strip 6 is arranged along the inner wall of the cavity 4. When illuminated, the light passes through the central light-transmitting area 71 of the light-shielding sheet and is evenly diffused by the panel 5 to form a soft light effect. When not illuminated, the panel 5 reflects external light, and the light-shielding sheet blocks the view, making the internal light strip completely invisible.

[0032] Compared to existing technologies, traditional solutions using rigid LED strips cannot adapt to curved surfaces and dynamic stresses. This solution, however, utilizes a flexible LED strip 6 that conforms to the inner wall, significantly improving structural adaptability and reliability. Existing light-shielding sheets rely on manual pasting, leading to positioning errors. This solution achieves precise positioning through the mechanical cooperation of the slot 2 and the insert plate 8, eliminating the risk of adhesive contamination. Conventional panels cannot conceal the internal structure. This solution combines a light-shielding sheet with a double-sided mirror panel 5, forming a complete reflective surface in the non-illuminated state, completely concealing the internal components. Through these technical solutions, this application solves the problem of arranging rigid LED strips on curved structures, avoiding breakage due to mechanical deformation; achieves rapid and precise positioning of the light-shielding sheet through an insert structure, ensuring uniform light efficiency; and utilizes the layered design of the light-shielding sheet and panel 5 to completely conceal the internal structure in the non-illuminated state, achieving an invisible effect.

[0033] In a specific implementation, the distance between the annular light-shielding plate 7 and the chamber opening 3 is substantially the same as the thickness of the panel 5, so that the outer surface of the panel 5 is substantially flush with the end face of the annular frame 1. The distance between the annular light-shielding plate 7 and the chamber opening 3 refers to the axial clearance between the mounting surface of the light-shielding plate and the opening end face of the frame 1, which can be achieved by adjusting the depth of the chamber 4 or the thickness of the light-shielding plate. This dimensional parameter is used for the final installation position of the control panel 5. The thickness of the panel 5 refers to the axial dimension of the light-transmitting plate covering the outside of the light-shielding plate, and this parameter directly determines the offset of the outer surface of the panel 5 relative to the end face of the frame 1.

[0034] Specifically, during assembly, the light-shielding plate is positioned at a predetermined position inside the chamber opening 3 via a plug-in structure. At this point, the gap between the light-shielding plate and the opening end face of the frame 1 is precisely set to be equal to the thickness of the subsequently installed panel 5. When the panel 5 is fixed to the outside of the light-shielding plate, its outer surface naturally extends to a state coplanar with the end face of the frame 1. This closed-loop control of the dimensional chain ensures that the light-shielding plate not only serves as an optical shielding element but also as a positioning reference for the installation of the panel 5, eliminating cumulative errors that may occur during assembly through dimensional matching of the mechanical structure.

[0035] The flexible light strip 6 employs a COB flexible light strip arrangement along the curved surface of the inner wall of the cavity 4. The COB flexible light strip refers to a light strip where LED chips are directly encapsulated on a flexible substrate to form a continuous light-emitting surface. This can be achieved using a polyimide substrate combined with silicone encapsulation technology. Its solderless, integrated structure eliminates the risk of solder joint detachment in traditional light strips. The arrangement along the curved surface of the inner wall of the cavity 4 means that the light strip is fitted and installed according to the curvature of the inner wall of the cavity 4. This is achieved through a pre-forming process to match the curvature of the light strip with the curvature of the inner wall of the cavity 4, ensuring complete contact between the light strip and the irregular curved surface. Specifically, the flexible substrate of the COB flexible light strip allows the light strip to bend freely in three-dimensional space, enabling it to closely fit the curved inner wall of complex irregular structures such as gaming table legs. After the pre-formed light strip is fixed to the inner wall of the cavity 4, its continuous light-emitting surface can evenly distribute light along the curved surface. Because the COB packaging process directly bonds the LED chip to a flexible substrate and covers it entirely with silicone, the light strip has no independent solder joint structure inside. Therefore, during the mechanical deformation caused by frequent lifting and lowering of the table legs, the light strip will not experience solder joint breakage or circuit damage due to bending stress. Compared with existing technologies, traditional rigid PCB light strips are limited by the hardness of the substrate and can only achieve straight lines or large-arc bending arrangements, making them unable to adapt to complex irregular curved surfaces, and prone to solder joint breakage under mechanical stress. In contrast, the COB flexible light strip, through its flexible substrate and solder joint-free packaging structure, can not only conform to the inner wall of any curved surface, but also fundamentally avoid the risk of solder joint detachment.

[0036] Furthermore, the COB flexible LED strip is fixed in one of the following ways:

[0037] Option 1 involves direct bonding to the inner wall of chamber 4. Direct bonding refers to utilizing the flexibility of the COB flexible LED strip to achieve complete contact with the curved surface of the inner wall of chamber 4. This can be achieved using pressure-sensitive adhesive or hot melt adhesive, through physical adsorption to ensure a seamless fit between the LED strip and the curved surface. Specifically, when using direct bonding, pressure is applied to the COB flexible LED strip during installation, causing it to stretch and deform, thus perfectly conforming to the curved contour of the inner wall of chamber 4. After curing, the adhesive forms a uniform bonding layer, preventing displacement of the LED strip due to mechanical vibration or temperature changes.

[0038] Option 2 involves embedding the LED strip into a groove in the inner wall of chamber 4. Embedding in a groove refers to inserting the COB flexible LED strip into a pre-machined continuous groove in the inner wall of chamber 4. This groove can be formed using injection molding or machine milling, and the sidewalls of the groove provide three-dimensional constraint on the LED strip. Specifically, when using the groove embedding method, the depth of the groove matches the thickness of the LED strip. After embedding, the upper and lower surfaces of the LED strip are flush with the bottom of the groove and the inner wall of chamber 4, respectively. The sidewalls of the groove provide a wrapping constraint on the edge of the LED strip, preventing lateral slippage or warping under dynamic stress. Both fixing methods achieve shape adaptation between the LED strip and the curved surface through mechanical structure or material properties, eliminating light effect interference caused by installation gaps.

[0039] In a further embodiment, panel 5 is constructed using an acrylic double-sided mirror. When the flexible light strip 6 is not emitting light, panel 5 shields the interior of chamber 4 by reflecting external light. The acrylic double-sided mirror refers to panel 5 made of acrylic material with a double-sided mirror structure. Specifically, it can be achieved using an acrylic sheet with a surface coated with a metal reflective film. Its double-sided reflective properties create a continuous mirror effect even when not emitting light. Reflecting external light refers to utilizing the specular reflection of incident light by the surface of panel 5. This can be achieved by adjusting the thickness and light transmittance of the reflective film layer, so that ambient light is reflected to form a complete shielding layer. Specifically, when the flexible light strip 6 is not powered on, when external light is incident on the surface of the acrylic double-sided mirror, its double-sided reflective film layer reflects most of the light back to the external environment, creating a continuous mirror effect, thereby completely shielding the flexible light strip 6, wiring structure, and edges of the light-shielding sheet inside chamber 4. When the flexible light strip 6 is powered on and emits light, the light penetrates the light-transmitting area in the center of the double-sided mirror and is projected outward. At this time, the transmittance of the reflective film layer to the internal light is higher than the reflectance of the external ambient light, so that the light effect can be effectively output.

[0040] In the specific implementation scheme, the edge of panel 5 is fixed to the outside of the annular light-shielding sheet 7 by adhesive bonding. Edge bonding means that adhesive is applied only to the contact area between the outer edge of panel 5 and the annular light-shielding sheet 7. This can be achieved by locally applying hot melt adhesive or UV adhesive, thus limiting the bonding area and preventing the adhesive from spreading into the light-transmitting area. The annular light-shielding sheet 7 is a sheet-like component with a central light-transmitting area 71, which can be made of injection-molded ABS plastic sheet. Its outer edge is inserted into the slot 2 of frame 1 for initial positioning, providing a reference plane for panel 5 installation. Specifically, after the annular light-shielding sheet 7 is inserted and positioned into the slot 2 of frame 1 via the insert plate 8, the operator only needs to cover the outside of the light-shielding sheet and apply adhesive along the contact edge. Since the light-shielding sheet has been pre-positioned spatially through mechanical insertion, panel 5 only needs to be linearly attached along its outer edge, ensuring that the outer surface of panel 5 is flush with the end face of frame 1 without additional position adjustments. During the bonding process, the adhesive is confined to the annular area at the edge to prevent it from penetrating into the central light-transmitting area 71 and causing optical contamination. This assembly method achieves rapid and precise installation of panel 5 through the synergistic effect of mechanical positioning and local bonding.

[0041] In a specific implementation plan, each inner wall of the annular frame 1 is provided with a slot 2, and each outer wall of the annular light-shielding sheet 7 is provided with an insert plate 8.

[0042] In this context, slot 2 refers to a guide structure that is continuously or intermittently distributed along the circumferential inner wall of the annular frame 1, used to constrain the insertion path and depth of the insert plate 8. Insert plate 8 refers to a protruding structure integrally formed or separately connected to the outer wall of the annular light-shielding plate 7, which can be implemented by stamping or insert injection molding, used to form a geometric fit with slot 2. Specifically, the inner wall of the annular frame 1 forms a positioning reference surface through the circumferentially distributed slots 2, and the annular light-shielding plate 7 achieves multi-point synchronous positioning through the cooperation of the insert plate 8 on the outer wall with the slot 2. When the insert plate 8 is inserted into the corresponding slot 2, the inner wall of the slot 2 and the side wall of the insert plate 8 make surface contact, restricting the radial and axial displacement freedom of the light-shielding plate. Because the slots 2 and insert plates 8 are evenly distributed along each inner wall of the annular frame 1, the light-shielding plate is symmetrically constrained during assembly, and its central light-transmitting area 71 automatically remains coaxially aligned with the opening of the frame 1.

[0043] Furthermore, after the insert plate 8 is initially positioned by being inserted into the slot 2, the annular light-shielding plate 7 and the annular frame 1 are fixed together by welding. Welding refers to melting the contact area between the annular light-shielding plate 7 and the annular frame 1 at high temperature to form a permanent connection. This can be achieved using laser welding or ultrasonic welding processes. The fusion of metal or plastic materials enhances the connection strength and avoids adhesive contamination of the light-transmitting area. Specifically, during assembly, the insert plate 8 at the edge of the annular light-shielding plate 7 is first inserted into the slot 2 of the annular frame 1. Precise initial positioning is achieved through the mechanical engagement of the slot 2 and the insert plate 8. After insertion, welding energy is applied to the contact area between the insert plate 8 and the slot 2, causing the materials at the contact surfaces to melt and solidify, forming a gapless permanent connection. This process, through the synergistic effect of mechanical positioning and welding, ensures the positional accuracy of the annular light-shielding plate 7 within the chamber 4, while simultaneously enhancing its resistance to displacement under mechanical stress.

[0044] In a further design, the annular frame 1 is a polygonal frame, formed by welding multiple pipes together. The polygonal frame refers to a closed annular structure with at least three sides, specifically a hexagonal or octagonal frame, whose geometric features at the corners match the curved contours of the irregularly shaped table legs. The welding of the pipes involves joining multiple independently processed straight or bent pipes at a predetermined angle using laser welding or argon arc welding. The continuous joints formed by the weld ensure the overall structural rigidity of the frame. Specifically, the pipes can be individually bent and face-processed before welding, reducing the overall processing difficulty of the irregularly shaped frame through modular production. During welding, the joint positions between the pipes are positioned using tooling fixtures to ensure dimensional accuracy at the joints, preventing assembly difficulties due to processing errors. After welding, the closed annular structure of the frame evenly distributes the mechanical stress generated during the raising and lowering of the table legs, preventing localized deformation.

[0045] In a specific implementation, the annular frame 1 has chamber openings 3 on both the front and rear sides of the chamber 4, and at least one of the chamber openings 3 is equipped with an annular light-shielding plate 7 and a panel 5. The annular frame 1 having chamber openings 3 on both the front and rear sides of the chamber 4 means that the frame structure forms openings in both directions. This can be achieved by welding metal tubing to form a polygonal frame structure, allowing the light source to project light from different directions. The fact that at least one of the chamber openings 3 is equipped with an annular light-shielding plate 7 and a panel 5 means that a combination of the light-shielding plate and the panel 5 is installed at at least one opening. Specifically, the light-shielding plate can be positioned using a slot 2 and an insert plate 8. This mechanical connection replaces traditional manual pasting, ensuring component positioning accuracy. In particular, the double-sided opening design of the annular frame 1 allows the light source to adapt to dual-sided light emission requirements, such as simultaneously creating light effects on both sides of a gaming table leg. When the light-shielding plate is inserted into the slot 2 on the inner wall of the frame 1 via the insert plate 8, its position is mechanically limited, preventing displacement caused by manual operation. Panel 5 is fixed to the outside of the light-shielding sheet by adhesive, and its thickness is flush with the end face of frame 1, hiding the internal structure when not emitting light. Flexible light strip 6 is arranged along the curved surface of the inner wall of chamber 4, and the light can only be emitted directionally through the light-transmitting area 71 in the center of the light-shielding sheet to form a uniform light effect.

[0046] In summary, the light-emitting structure with invisible light effect provided in this application and its application achieve precise positioning of the annular light-shielding sheet 7 through the insertion and cooperation of the slot 2 and the insert plate 8. Combined with the flexible light strip 6 arranged along the curved surface and the double-sided mirror characteristics of the panel 5, it solves the problems of large installation deviation, light leakage and easy damage of rigid light strips in traditional structures. It has the advantages of improving installation accuracy, avoiding light leakage and improving structural reliability.
