Description

Technical Field

[0001] This utility model relates to the field of tabletop lighting technology, and in particular to a light-emitting tabletop and cabinet. Background Technology

[0002] In the current industry, the most common method for creating illuminated countertops is to directly attach LED light strips to the back of a single piece of natural or artificial luxury stone, relying on the stone's own light-transmitting properties to achieve an internal luminous effect. However, this technology has significant shortcomings: light cannot penetrate the stone evenly, easily resulting in uneven brightness and visible light spots, which seriously affect visual appeal and user experience.

[0003] To improve light emission uniformity, some existing technologies have introduced light guide plate structures, with LED strips arranged around the four edges of the light guide plate. Despite the introduction of light guide plates, this "side-in light" method, which only places LED strips on the four sides, does not fundamentally solve all the problems. Because light enters from all four sides, the brightness is highest at the edges of the light guide plate, while the light attenuates as it propagates towards the center, resulting in a significantly lower brightness at the center of the countertop compared to the surrounding areas, creating a so-called "dark spot" phenomenon, and the uniformity remains unsatisfactory. Furthermore, this solution requires an additional light guide plate assembly beyond the stone and LED strips, and its sides need to be precisely machined to accommodate the LED strip installation. This not only increases material costs but also significantly increases the complexity of the structural design, assembly, and alignment processes, as well as production costs. Utility Model Content

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model uses a light-emitting panel instead of a traditional light strip as the light-emitting unit, fully utilizing the inherent uniform light source characteristics of the light-emitting panel. Combined with the stable support of the fixing frame, it ensures that the light can directly and vertically illuminate the stone panel, achieving uniform illumination without dark areas and significantly improving the luminous effect of the stone panel.

[0036] In the description of this utility model, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0037] Please see Figures 1-10 As shown, the present invention provides a light-emitting tabletop, comprising a light-transmitting stone panel 1, a light-emitting panel 3, and a fixing frame 2. The fixing frame 2 is fixed to the back of the stone panel 1, and the light-emitting panel 3 is installed on the fixing frame 2, with the light-emitting surface of the light-emitting panel 3 facing the stone panel 1. There is an air gap between the light-emitting surface of the light-emitting panel 3 and the stone panel 1. The size of this air gap in the thickness direction of the stone panel 1 is preferably 15-20mm to facilitate light diffusion and improve the light emission effect of the stone panel 1.

[0038] In a preferred embodiment, the present invention provides a receiving groove 13 on the back of the stone panel 1, and the fixing frame 2 is disposed within the receiving groove 13, specifically, the fixing frame 2 is adhered to the receiving groove 13. This design allows the fixing frame 2 to be embedded, which helps to reduce the overall thickness and improve the compactness of the overall structure. After the receiving groove 13 is provided on the stone panel 1, the thickness of the area of ​​the stone panel 1 with the receiving groove 13 is reduced. In this way, not only is the heaviness of the stone panel 1 reduced, but its light emission effect is further improved (the thinner the stone panel 1, the easier it is to emit light). Furthermore, the light-emitting panel 3 also enters the receiving groove 13 of the stone panel 1, and neither the light-emitting panel 3 nor the fixing frame 2 protrudes from the receiving groove 13, so that the light-emitting panel 3 and the fixing frame 2 are hidden outside the receiving groove 13 and are not exposed in the lateral direction, thereby making the overall structure more compact and beautiful.

[0039] like Figure 2 As shown, the stone panel 1 includes a main body 11 and multiple edge strips 12. The main body 11 and the edge strips 12 together form the aforementioned receiving groove 13. Taking four edge strips 12 as an example, the surrounding outline of the receiving groove 13 is square. The main body 11 and the edge strips 12 are derived from the same piece of stone slab 7, and their processing is as follows... Figure 4As shown: The stone slab 7 is cut from a large stone slab 6 of suitable size. The stone slab 7 has a certain degree of flexibility. A shallow groove 71 is formed by partially cutting along the back of the stone slab 7. The shallow groove 71 is then polished and repaired. The shallow groove 71 divides the stone slab 7 into a central main body 11 and four outer edge strips 12. The four edge strips 12 are cut at 45° at their ends, so that the ends of adjacent edge strips 12 are separated from each other. Each of the multiple edge strips 12 is bent towards the back of the main body 11 along the shallow groove 71, and the adjacent ends of adjacent edge strips 12 are joined at 45° by adhesive to form a rim that matches the back of the main body 11, together forming a receiving groove 13. The composition and processing method of the stone panel 1 are not limited to this. In other embodiments, the stone panel 1 includes a stone body and a stone base frame adhered to the back of the stone body. The inner side of the stone base frame and the back of the stone body together form a receiving groove 13. In other embodiments, the stone panel 1 includes a stone body and multiple stone edge strips adhered to the four edges of the back of the stone body. The multiple stone edge strips are spliced ​​together end to end to form a closed structure, which together with the back of the stone body forms the receiving groove 13.

[0040] The light-emitting panel 3 is mounted on the back of the fixing frame 2. Preferably, the back of the fixing frame 2 has a recessed groove 21 surrounding it. The recessed groove 21 includes an outer wall and a bottom wall, and its longitudinal cross-section is L-shaped. The edges of the light-emitting panel 3 are connected to the recessed groove 21, and the light-emitting panel 3 does not protrude from the recessed groove 21 in its thickness direction. The outer wall of the recessed groove 21 has a clearance notch 22 to avoid the power cord connected to the light-emitting panel 3. The end of the power cord has a quick-connect terminal for quick connection or disconnection from the power supply box. The recessed groove 21 design helps to further reduce the overall thickness, thereby further improving the compactness of the overall structure.

[0041] In a preferred embodiment, the light-emitting panel 3 and the fixing frame 2 are detachably connected by a snap-fit ​​structure, making it easier to assemble and disassemble the light-emitting panel 3, thus facilitating its maintenance and replacement. Specifically, the snap-fit ​​structure includes multiple snaps 4 located in one of the light-emitting panel 3 and the fixing frame 2, and multiple slots 23 located in the other of the light-emitting panel 3 and the fixing frame 2, with the snaps 4 and slots 23 engaging one-to-one. In this embodiment, the snaps 4 are located in the light-emitting panel 3 and the slots 23 are located in the fixing frame 2, but this is not a limitation. Since the four edges of the light-emitting panel 3 are connected to the recessed groove 21 on the back of the fixing frame 2, the slots 23 are located on the bottom wall of the recessed groove 21, and there are four slots 23, each divided into two groups and distributed on opposite sides of the bottom wall of the recessed groove 21. There are also four snaps 4, each divided into two groups, distributed on opposite sides of the front of the light-emitting panel 3. The number of clips 4 and slots 23 is not limited to four. Slots 23 can be through slots that run vertically or blind slots that do not run vertically.

[0042] Furthermore, the slot 23 includes a guide groove 231 and a locking groove 232 that are laterally connected. The buckle 4 includes a buckle arm 41 and a buckle head 42 located at the tail end of the buckle arm 41. The buckle head 42 enters the slot 23 through the guide groove 231 and completes the fastening by sliding to the locking groove 232. When unfastening, the buckle head 42 slides back to the guide groove 231 to exit the slot 23. Specifically, in this embodiment, the guide groove 231 and the locking groove 232 are distributed along the length direction of the fixing frame 2, and the guide groove 231 of each slot 23 is located on the same side of the corresponding locking groove 232. The length of the light-emitting panel 4 is less than the inner length of the fixing frame 2, so that the light-emitting panel 4 has disassembly space.

[0043] The fixing frame 2 is made of aluminum alloy, and its manufacturing process is as follows: First, the aluminum alloy profile (which is hollow) is cut and spliced ​​at 45° to obtain the semi-finished product of fixing frame 2; then, the back of the semi-finished product of fixing frame 2 is stamped and milled to form the required recess 21, four slots 23 and clearance notch 22, and finally the finished product of fixing frame 2 is obtained.

[0044] The assembly steps of this utility model for a light-emitting tabletop are as follows: First, the fixing frame 2 is glued and fixed into the receiving groove 13 pre-cut on the back of the stone panel 1; then, the light-emitting panel 3 is installed into the recessed groove 21 on the back of the fixing frame 2 by means of a snap-fit ​​4. During this process, the power cord of the light-emitting panel 3 is led out through the clearance notch 22 provided in the side wall of the fixing frame 2, so that the overall outer surface of the light-emitting panel 3 and the fixing frame 2 is flush or nearly flush with the outer edge of the receiving groove 13 of the stone panel 1, thereby achieving a flat and stable built-in light-emitting structure.

[0045] This invention uses a light-emitting panel 3 instead of a traditional light strip as the light-emitting unit, fully utilizing the inherent uniform light source characteristics of the light-emitting panel 3 and eliminating the need for an additional light guide plate. Combined with the stable support of the fixing frame 2, it ensures that light can directly and vertically illuminate the stone panel 1. The air gap between the light-emitting panel 3 and the stone panel 1 helps to evenly diffuse the light, achieving uniform illumination without dark areas and significantly improving the luminous effect of the stone panel 1. Therefore, the design of this invention eliminates the need for an additional expensive light guide plate and a complex side light strip fixing structure, thereby significantly reducing production costs and simplifying the production process.

[0046] Please see Figures 1-12 As shown, a cabinet according to the present invention includes a cabinet body 8 and a light-emitting tabletop as described above, which is fixed to the top of the cabinet body 8.

[0047] Furthermore, the top of the cabinet 8 is open, covered by a light-emitting surface. A waterproof power supply box 9 is installed inside the cabinet 8, which is electrically connected to the light-emitting panel 3. Specifically, the power supply box 9 achieves electrical connection between the light-emitting panel 3 and the power supply box 9 by quickly connecting the quick-connect terminal 51 at the end of the power cord 5 of the light-emitting panel 3 to the DuPont terminal 10 on the power supply box 9. This power supply box 9 not only supplies power to the light-emitting panel 3 but also controls the on / off state and / or switches the light emission color of the light-emitting panel 3.
