Description

Technical Field

[0001] This application relates to the field of customized furniture technology, and in particular to a rear-mounted shelf light structure and furniture cabinet. Background Technology

[0002] Currently, 12mm thin shelving is widely used in high-end custom furniture due to its lightweight and minimalist design. However, existing cabinet lighting products are mostly designed for 18mm shelving, resulting in bulky products that are difficult to conceal and install, affecting the overall aesthetics. A common solution involves two light strips for bidirectional illumination, which is costly, energy-intensive, and cumbersome to install. Using silicone lampshades can also cause uneven adhesion, resulting in wavy light and poor light quality. Therefore, existing technologies struggle to balance thin-sheet compatibility, ease of installation, and high-quality lighting. Utility Model Content

[0003] This application provides a rear-mounted shelf light structure and a furniture cabinet to at least partially solve the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a rear-mounted shelf light structure is provided, applied to a furniture cabinet, the furniture cabinet including a back panel and shelves, wherein an installation gap is reserved between the back panel and the shelves, characterized in that the rear-mounted shelf light structure includes:

[0005] A mounting plate is configured to be attached to the side of the shelf facing the mounting gap;

[0006] A light strip is attached to the surface of the mounting plate facing the mounting gap;

[0007] A light shield is attached to the mounting plate and located within the mounting gap, forming a light-emitting space between the light shield and the mounting plate, and the light strip is located within the light-emitting space; wherein...

[0008] The light shield has a reflector located directly opposite the light strip. The surface of the reflector facing the light strip is a reflective surface. The reflector is used to reflect the light emitted by the light strip to the upper and lower sides of the light shield.

[0009] In one embodiment, the mounting plate has an overlap portion that extends out of the mounting gap and is bonded to the upper surface of the layer.

[0010] In one embodiment, the mounting plate has a limiting portion spaced apart on the surface of the plate opposite to the layer plate, and the light strip is installed between two of the limiting portions.

[0011] In one embodiment, the light shield has snap fasteners on both sides of its sides, and the mounting plate has snap grooves on the inner sides of both sides of its sides, with the snap fasteners embedded in the snap grooves.

[0012] In one embodiment, the mounting plate has a blocking portion on the inner side of both sides of its edge. The blocking portion is located on the side of the snap-fit ​​groove away from the snap-fit ​​buckle. The blocking portion is used to engage with the snap-fit ​​buckle embedded in the snap-fit ​​groove.

[0013] In one embodiment, the reflector includes a reflective strip and protrusions. The reflective strip is located on the light shield directly opposite the light strip. The reflective surface is the surface of the reflective strip directly opposite the light shield. Multiple protrusions are spaced apart on the reflective surface, and a groove is formed between two adjacent protrusions.

[0014] In one embodiment, the reflective strip has an arc-shaped cross-section, and the reflective surface protrudes towards the side of the light strip, while the surface of the reflective strip facing the back plate is recessed away from the back plate.

[0015] According to a second aspect of this application, a furniture cabinet is provided, including the rear shelf light structure described in the first aspect, and further including a back panel and shelves, wherein an installation gap is reserved between the back panel and the shelves.

[0016] The beneficial effects of the embodiments of this application are as follows:

[0017] 1. A rear-mounted shelf light structure, formed by installing a mounting plate, light strip, and light shield between the shelf and the back panel, conceals the light strip within the installation gap, avoiding direct exposure and glare. Simultaneously, the light-emitting space enclosed by the light shield and mounting plate provides flexible and uniform illumination. Light can be diffused along the top and bottom sides of the light shield into the cabinet interior, improving lighting uniformity and visual comfort. Reflectors are located inside the light shield, guiding the direct light from the light strip to both sides through the reflective surface, achieving efficient light energy utilization and reducing light spots. The overall structure is concealed and provides soft lighting, solving the problems of strong glare, limited illumination range, and aesthetic impact of traditional shelf lights.

[0018] 2. By incorporating limiting parts, overlapping parts, snap-fit ​​grooves, and blocking parts on the mounting plate, along with snap-fit ​​buckles on both sides of the light shield, the lamp body structure achieves rapid assembly and stable positioning. The limiting parts ensure precise installation of the light strips, preventing displacement that could lead to light deviation; the snap-fit-groove-blocking structure provides a reliable anti-loosening locking effect, facilitating maintenance and replacement. This combined design not only improves assembly efficiency and structural stability but also enables convenient assembly and disassembly in confined installation spaces, solving the technical problems of complex installation, easy loosening, and difficult maintenance of traditional cabinet lighting fixtures.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0032] This embodiment discloses a rear-mounted shelf light structure and furniture cabinet. Its technical concept aims to adapt to thin shelf structures of 12mm or more thickness, achieving bidirectional light emission within the limited space between the back panel 1 and the shelf 2 while maintaining the overall aesthetics of the furniture cabinet. This satisfies the aesthetic demand for integrated light and shadow atmosphere and structure in modern minimalist homes. This embodiment improves the geometric design and fit of core structures such as the mounting plate 4, light strip 5, light shield 6, and reflector 7, enabling uniform light scattering over short distances and soft top and bottom lighting, while also considering structural strength, ease of assembly, and maintenance feasibility.

[0033] Firstly, combining Figure 1 , Figure 2 This application provides a rear-mounted shelf light structure for use in a furniture cabinet. The furniture cabinet includes a back panel 1 and shelves 2, with a pre-reserved installation gap 3 between the back panel 1 and the shelves 2. This gap is typically 8mm to 10mm wide and is used to accommodate the rear-mounted shelf light structure. In this embodiment, the rear-mounted shelf light structure consists of a mounting plate 4, a light strip 5, a light shield 6, and a reflector 7, etc. The cooperation between these components forms a complete light-emitting system.

[0034] For example, the mounting plate 4 is disposed on the side of the shelf 2 facing the mounting gap 3, and is fixedly connected to the shelf 2 by structural bonding or fitting. The mounting plate 4 serves to support the light strip 5, connect the light shield 6, and limit the direction of light emission.

[0035] For example, the mounting plate 4 can be made of aluminum alloy profile, which has better thermal conductivity than plastic parts. It can play a certain role in heat dissipation when the light strip 5 is working, which is beneficial to maintaining the light strip 5 at a stable temperature for a long time and avoiding light decay and structural thermal deformation. The thickness of the mounting plate 4 can be determined according to the space dimensions of the shelf 2, generally 1.0mm to 1.5mm, which can ensure strength without taking up too much space.

[0036] In some implementations, refer to Figure 1 , Figure 2 A light strip 5 is installed on the side of the mounting plate 4 facing the mounting gap 3.

[0037] For example, the light strip 5 is in the form of a flexible circuit board, on which several light-emitting diodes (LEDs) are evenly distributed.

[0038] Furthermore, the light strip 5 emits light towards the interior space of the light shield 6, thus forming a controllable light channel within the limited space. The light strip 5 is attached to the surface of the mounting plate 4 using double-sided thermally conductive adhesive, allowing the heat generated by the LEDs to be guided through the aluminum substrate to the mounting plate 4 and then transferred to the shelf 2, thus providing passive heat dissipation. The power leads of the light strip 5 extend from the edge of the mounting plate 4 to the back of the cabinet, connecting to the driver power supply. The number and layout of the light strips 5 are determined based on the width of the shelf 2 and the lighting requirements; generally, a single high-density light strip is used to ensure continuous light distribution and uniform illumination.

[0039] In some implementations, reference is made to Figure 1 , Figure 2 The light shield 6 is mounted on the mounting plate 4 and embedded in the mounting gap 3. The light shield 6 and the mounting plate 4 together enclose a closed light-emitting space. The formation of this light-emitting space allows light to be reflected and scattered inside the light shield 6 before being emitted outward, reducing glare and improving the softness of the light.

[0040] For example, the light shield 6 is made of PC or PMMA co-extruded material, with a semi-transparent layer on the side near the reflector 7 and a diffuser layer on the other side. The semi-transparent layer helps to refract and redistribute light, and the diffuser layer can uniformly scatter reflected light, thereby forming a soft light band in both the vertical and horizontal directions.

[0041] In some implementations, reference is made to Figure 1 , Figure 2 The two sides of the light shield 6 have snap fasteners 61, and the two sides of the mounting plate 4 have snap grooves 43 on the inner side of the two sides. The snap fasteners 61 are embedded in the snap grooves 43.

[0042] It is understandable that the snap-fit ​​61 matches the snap-fit ​​groove 43 corresponding to the inner edge of both sides of the mounting plate 4. The snap-fit ​​engagement method allows the sunshade 6 to be quickly assembled without tools, while also providing convenient disassembly.

[0043] In some implementations, reference is made to Figure 1 , Figure 2 To prevent the light shield 6 from loosening due to vibration or thermal expansion and contraction during cabinet use, the inner sides of both edges of the mounting plate 4 are also provided with blocking parts 44. The blocking parts 44 are located on the side of the snap-fit ​​groove 43 away from the snap-fit ​​buckle 61. The blocking parts 44 are used to stop and cooperate with the snap-fit ​​buckle 61 embedded in the snap-fit ​​groove 43.

[0044] It is understandable that when the latch 61 is inserted into the latch slot 43, the blocking part 44 and the latch 61 abut against each other, thereby limiting the axial displacement of the light shield 6 to a certain extent and keeping the entire light-emitting structure stable.

[0045] In some implementations, reference is made to Figure 1 , Figure 2The mounting plate 4 also includes an overlapping portion 41, which extends out of the mounting gap 3 and is bonded to the upper surface of the shelf 2. It can be understood that the overlapping portion 41 extends from the main body of the mounting plate 4 out of the mounting gap 3 and is bonded to the upper surface of the shelf 2. This structure helps improve the stability of the lamp body, enhances the mechanical connection strength with the shelf 2, and maintains a smooth transition in appearance, making the part of the lamp body embedded in the edge of the shelf 2 appear natural and concealed.

[0046] It is worth noting that the width of the overlap 41 can be adjusted according to the thickness of the shelf 2 and the distance to the back panel 1 to accommodate different furniture structures. This overlap method reduces the use of screws or brackets in the structure, which is beneficial for later maintenance and replacement of the light strip 5. It also avoids the damage to the integrity of the shelf 2 substrate caused by traditional drilling fixing methods and reduces the risk of moisture absorption and deformation.

[0047] In some implementations, refer to Figure 1 , Figure 2 Two limiting parts 42 are provided at intervals on the side of the mounting plate 4 opposite to the layer plate 2. The limiting part 42 is an outwardly protruding block or a stepped flange, used to limit the installation position of the light strip 5. An installation groove is formed between two adjacent limiting parts 42, and the light strip 5 is installed in the groove by adhesive or embedding. The presence of the limiting parts 42 ensures that the position of the light strip 5 remains accurate during installation and prevents uneven light distribution due to adhesive misalignment.

[0048] For example, the limiting structure also applies a certain amount of pressure to the light strip 5, making it adhere more firmly and less likely to fall off during transportation or long-term use. The height design of the limiting part 42 needs to take into account both the adhesive thickness and heat dissipation effect, and is usually between 0.3mm and 0.5mm.

[0049] In some implementations, reference is made to Figure 1 , Figure 2 The reflector 7 is positioned directly opposite the light strip 5 to the light shield 6, and is used to change the light propagation path. The reflector 7 includes a reflector strip 71 and multiple protrusions 72 arranged on the surface of the reflector strip 71. The reflector strip 71 can be made of aluminum coating or a highly reflective white material, and its side facing the light strip 5 forms a reflective surface.

[0050] For example, the cross-sectional shape of the reflective strip 71 is arc-shaped, and the reflective surface protrudes towards the side of the light strip 5, while the surface of the reflective strip 71 facing the back plate 1 is recessed away from the back plate 1.

[0051] It is understandable that this geometric shape causes light to be reflected and diffused at multiple angles after it first hits the reflective surface. The protrusions 72 and adjacent grooves 73 form periodic reflective units. Each unit refracts and reflects light in different directions, causing the light to scatter multiple times in space, thus forming a continuous and soft light band in the vertical direction. By adjusting the spacing and height of the protrusions 72, different light distribution characteristics can be obtained. When the spacing of the protrusions 72 is small, the reflection density increases and the light output is more uniform; when the spacing is moderate, the light and shadow layers are more obvious, and the visual effect is more three-dimensional. This structure effectively improves the wavy light and shadow phenomenon caused by direct light shining on the back plate 1 in traditional lamps, making the light output effect smooth transition.

[0052] In some embodiments, the reflector 7 and the light shield 6 can be assembled using co-extrusion molding or snap-fit ​​methods. Co-extrusion is suitable for mass production, ensuring the precision of the connection between the reflector 7 and the light shield 6; snap-fit ​​methods facilitate the replacement of components with different reflective characteristics to meet the lighting needs of different cabinets. The reflective layer of the reflective surface can be vacuum-plated aluminum or a high-reflectivity coating process, with a reflectivity generally in the range of 85% to 95%. Through multiple reflections, the light energy emitted by the light strip 5 is effectively directed to the light-emitting areas on the upper and lower sides, thereby forming a wide light band lighting effect over a short distance.

[0053] It is understandable that the light emitted from the light strip 5, after being reflected by the reflector 7, is scattered upwards and downwards through the semi-transparent layer of the light shield 6. The light then undergoes secondary diffusion on the surface of the diffuser layer, forming a uniform bright band. Because the light shield 6 is partially embedded in the installation gap 3, the entire light body is almost not exposed, maintaining a clean and continuous visual line for the cabinet. When the light body is lit, the soft light boundaries formed by the upper and lower edges provide ambient lighting for the interior space of the cabinet, while avoiding direct glare that could affect visual comfort. This light distribution pattern is particularly suitable for structures such as open shelves, display cabinets, or bookcases, highlighting the texture and layering of displayed items through the interplay of light and shadow.

[0054] In terms of installation, this rear-mounted shelf light structure requires no additional fasteners; it can be secured using a snap-fit ​​mechanism. For users or installers, the entire light body can be directly inserted into the gap between shelf 2 and back panel 1 from the back of the cabinet, and positioned by gently pressing it in. During later maintenance, the light shield 6 can be slightly pulled outwards to detach from the snap-fit ​​slot 43, facilitating the replacement of the light strip or cleaning of dust. This structure simplifies installation and maintenance procedures, saves labor costs, and reduces structural damage that may be caused by traditional screw installation.

[0055] To accommodate shelves 2 with a thickness of 12mm and above, this embodiment optimizes the overall thickness design of the lamp body. The overall thickness of the mounting plate 4, when fitted with the light shield 6, is approximately 8mm, leaving sufficient space for a heat dissipation air layer. This size is compatible with common 12mm thin shelf 2 structures and is also applicable to 18mm thick shelf 2. This compact design integrates the lighting components with the cabinet structure, without affecting the load-bearing capacity and stability of the shelf 2, nor compromising the mechanical properties of the material.

[0056] In terms of lighting effects, the optical coordination between the reflector 7 and the light shield 6 allows light to undergo three stages—reflection, scattering, and diffusion—in the back space, ensuring full utilization of light energy within a limited space. The shortened back-facing light path facilitates the formation of a high-brightness, uniform light strip while reducing energy loss and improving lighting efficiency. The luminous intensity of the light strip 5 can be selected according to the cabinet size, with common specifications ranging from 4.8W / m to 9.6W / m. Combined with the reflection system, it can achieve the illuminance level of a traditional dual light strip 5, reducing energy consumption and heat accumulation.

[0057] This rear-mounted shelf light structure can also be applied to various types of furniture cabinets, including display cabinets, wardrobes, and wall-mounted cabinets. When the light body is installed in the space between the back panel 1 and the shelf 2, the overall appearance remains simple, the lighting effect is soft and uniform, and it enhances the overall texture of the furniture and the atmosphere of the space. Because it uses aluminum profiles as the structural base, the entire light body is lightweight, high-strength, and has good deformation resistance, making it suitable for mass production and modular assembly. By replacing the light shield 6 with different light transmittance or the reflector strip 71 with different reflection angles, various lighting effects can be obtained according to the usage scenario, such as focused illumination, ambient lighting, or uniform lighting.

[0058] In summary, the rear-mounted shelf lamp structure of this embodiment has significant advantages in terms of structural compactness, ease of assembly, and lighting quality. Through a reasonable optical design and mechanical coordination, it achieves bidirectional lighting effects from both top and bottom within 12mm thin-panel furniture, meeting the design requirements of modern homes for concealed light sources and soft lighting. This structure creates a unified effect between the lamp and the furniture, combining functionality and aesthetics, making it suitable for widespread application in the high-end custom furniture sector.
