Description

Technical Field

[0001] This utility model relates to a lamp and a display cabinet with double-sided light emission. Background Technology

[0002] With the increasing demands for lighting environments in commercial displays, museum exhibitions, home decoration, and other fields, built-in LED light strips are being widely adopted due to their advantages such as energy saving, high brightness, and long lifespan.

[0003] Currently, most display cabinet lights on the market are installed by cutting grooves in the cabinet structure (such as side panels, back panels, or shelves), embedding flexible LED light strips, and then fixing them with clips or covers.

[0004] However, this slotted installation method has the following drawbacks:

[0005] (1) Grooving requires the use of professional tools and high skill requirements for construction personnel. The depth and width of the groove must be precisely controlled to ensure that the light strip is inserted smoothly and the buckle is assembled, while avoiding damage to the strength and aesthetics of the cabinet structure;

[0006] (2) If the construction is improper or the design of the groove location and size is unreasonable, it is easy to damage the cabinet material, resulting in a reduction in the load-bearing capacity or service life of the cabinet;

[0007] (3) Soft LED strips need to be fixed by buckles or adhesive. If buckles are not used or the strip is stretched or not flat, especially at corners and groove edges, the strip is prone to bending, lifting or denting, resulting in alternating light and dark, light spots or dark areas, which cannot meet the lighting requirements of high uniformity.

[0008] (4) If the position of the light strip needs to be changed or adjusted after it is embedded, it is necessary to cut grooves or disassemble the cabinet panels again, which is time-consuming and labor-intensive and affects the overall efficiency of use. Utility Model Content

[0009] The primary objective of this invention is to provide a lamp with a simple structure and double-sided light emission.

[0010] The second objective of this utility model is to provide a display cabinet that does not require pre-embedded LED strips by slotting the back panel, side panel, or shelves of the cabinet.

[0011] The primary objective of this invention is achieved as follows:

[0012] A double-sided light-emitting lamp includes an H-shaped profile, a support plate, an upper lampshade, an upper light strip, a lower lampshade, and a lower light strip. The support plate is disposed on the side wall of the H-shaped profile, and the support plate and the H-shaped profile are integrally formed.

[0013] The upper light strip is set inside the upper groove of the H-shaped profile, and the upper lamp cover is set at the upper open opening of the upper groove and closes the upper open opening;

[0014] The lower light strip is installed inside the lower groove of the H-shaped profile, and the lower light cover is installed at the lower open opening of the lower groove and closes the lower open opening.

[0015] The H-shaped profile and support plate integrated design adopted in this invention effectively simplifies the manufacturing process and assembly of the lamp, avoids the accumulation of errors caused by the assembly of multiple parts in traditional lamps, and ensures the stability and dimensional accuracy of the overall structure.

[0016] By installing LED strips and corresponding lampshades in the upper and lower slots of the H-shaped profile, a true double-sided lighting effect is achieved.

[0017] The closed design of the upper and lower lamp covers not only provides a uniform and soft optical effect, eliminating the uneven brightness problem that is common in traditional light troughs, but also effectively prevents dust and moisture, extends the service life of LED light strips, and reduces maintenance costs.

[0018] The primary objective of this utility model can also be achieved by the following technical measures:

[0019] Furthermore, the bottom of the upper slot is provided with an upper light strip retaining groove, in which the upper light strip is retained; the top of the lower slot is provided with a lower light strip retaining groove, in which the lower light strip is retained.

[0020] By setting locking slots that match the shape of the light strip at the upper and lower openings, precise positioning and secure fixing of the light strip are achieved. On the one hand, the locking slots prevent the light strip from shifting due to vibration or external force, ensuring the long-term stability of the double-sided light-emitting position; on the other hand, the locking installation method simplifies the installation and removal process of the light strip. Maintenance or replacement only requires easy snapping or pulling out, improving maintenance efficiency and reducing maintenance costs.

[0021] Furthermore, the inner wall of the upper slot has an upper locking opening, and the upper lampshade is provided with an upper locking foot. The upper locking foot is inserted into the upper locking opening to lock the upper lampshade in the upper slot. The inner wall of the lower slot has a lower locking opening, and the lower lampshade is provided with a lower locking foot. The lower locking foot is inserted into the lower locking opening to lock the lower lampshade in the lower slot.

[0022] The upper and lower lampshades are assembled using a snap-fit ​​mechanism with clips and slots, allowing for secure fixation without the need for additional fasteners. This design ensures reliable support and optical sealing for the lampshades while also making installation and removal quicker and easier. It facilitates on-site adjustments to the lampshade position or replacement of lampshade materials, further enhancing the flexibility of installation and maintenance.

[0023] Furthermore, the H-shaped profile is an aluminum H-shaped profile, and the support plate is an aluminum support plate.

[0024] Aluminum, with its excellent strength-to-weight ratio and superior heat dissipation, provides reliable mechanical support and a heat conduction path for LED light strips, extending LED lifespan and improving luminous efficacy stability. Furthermore, aluminum surfaces are easily anodized and treated to meet decorative requirements, giving the lighting fixtures both structural performance and aesthetic appeal.

[0025] Furthermore, the support plate has bolt holes spaced apart.

[0026] Pre-drilled bolt holes on the support plate provide a standardized interface for optional bolt fastening. Bolt fastening and snap-fit ​​installation can be flexibly combined. For different installation environments and load requirements, users can choose snap-fit ​​only or snap-fit ​​+ bolt dual fixation to enhance overall stability and vibration resistance, thereby improving structural adaptability.

[0027] The second objective of this utility model is achieved as follows:

[0028] A display cabinet includes a cabinet body and shelves, the cabinet body including side panels and a back panel, the side panels being respectively disposed on both sides of the back panel to form the cabinet body;

[0029] The shelf is placed inside the cabinet cavity, and the side of the shelf is connected to the corresponding side panel. A lamp holder groove is formed between the rear of the shelf and the back panel.

[0030] The H-shaped profile is placed in the lamp holder slot, and the lamp holder slot and the H-shaped profile are interference-fitted. The support plate abuts against the surface of the shelf.

[0031] By designing interference-fit lighting fixture slots between the shelves and the back panel, quick "snap-in" installation of the lights is achieved, eliminating the need for additional slots or holes in the cabinet panels, significantly reducing construction difficulty and installation time. Simultaneously, after snapping in, the support plate adheres tightly to the shelf surface, ensuring the double-sided lighting fixtures are firmly integrated with the overall cabinet structure, enhancing the overall aesthetics and load-bearing safety of the display case.

[0032] The second objective of this utility model can also be achieved by the following technical measures:

[0033] Furthermore, double-sided adhesive is provided between the surfaces of the support plate and the layer plate.

[0034] Adding double-sided adhesive to the contact surface between the support plate and the shelf provides extra bonding strength, preventing the luminaire from loosening when subjected to slight vibration or displacement, thereby further improving installation stability.

[0035] Furthermore, it also includes bolts that pass through bolt holes to lock the layer.

[0036] The addition of a bolt fastening structure provides a mechanical lock for the snap-fit ​​installation, meeting safety requirements when bearing heavy displays or operating under vibration. Once the bolts are tightened, a reliable rigid connection is formed between the lighting fixtures and the shelves, enhancing resistance to lateral movement and ensuring the stability and safety of the display case.

[0037] Furthermore, it also includes bolts, with double-sided adhesive provided between the surfaces of the support plate and the shelf, and the bolts passing through bolt holes to lock the shelf.

[0038] By combining the adhesive properties of double-sided tape with the mechanical locking of bolts, the stability and reliability of the lighting fixtures are maximized under various usage conditions.

[0039] Furthermore, the side panel is provided with support rods spaced apart towards the inner cavity of the cabinet, and the shelf is placed inside the cabinet and sits on the corresponding support rod, so as to realize the detachable connection between the shelf and the side panel.

[0040] The combined load-bearing structure of the support rods and shelves eliminates the need for bolts or adhesives on the side panels, allowing for quick assembly and disassembly of the shelves. This enables users to flexibly adjust the shelf height according to display needs while maintaining the overall structural stability. This design not only simplifies the assembly process of the display case but also enhances maintainability and operational flexibility.

[0041] The beneficial effects of this utility model are as follows:

[0042] This utility model utilizes the interference fit between the H-shaped profile and the lamp mounting slot to achieve integrated installation of "alignment-insertion-clamping", eliminating the need for grooving, drilling or special tools, greatly shortening the construction cycle and reducing labor costs.

[0043] This utility model has pre-drilled bolt holes on the support plate, which can provide additional mechanical locking for the lamps by fastening the bolts through the holes, thereby enhancing their resistance to vibration and lateral displacement and meeting the safety requirements under high load or dynamic environments.

[0044] This utility model adds double-sided adhesive to the contact surface between the support plate and the shelf, which, combined with the double fixing of the snap-fit ​​and bolts, forms a triple locking structure to maximize the anti-loosening effect, and also has the functions of buffering, vibration reduction and dustproof sealing.

[0045] This utility model achieves a detachable connection between the shelf and the side panel by setting a support rod along the inner edge of the side panel to support the weight of the shelf. This ensures overall stability and allows for easy adjustment of the shelf height and layout according to display needs. Attached Figure Description
