Description

Technical Field

[0001] This utility model relates to the field of LED lighting equipment structure technology, and in particular to an LED ceiling light structure with anti-fall function. Background Technology

[0002] LED ceiling lights are widely used in residential, commercial, and public buildings due to their energy-saving, aesthetically pleasing, and easy-to-install features. With the development of modular lighting design, many ceiling lights adopt detachable light panels and shades for easy replacement and maintenance. However, the common "snap-on" or "rotation-positioning" structures in existing technologies are prone to detachment of the light source module or shade structure due to misoperation, fatigue, or loosening under frequent disassembly or vibration, posing a safety hazard. This is especially true in high-rise buildings or areas with high foot traffic, where the risk of falling lights poses a serious threat to personal safety. Therefore, there is an urgent need for an LED ceiling light with a reliable anti-fall structure that improves safety and stability while maintaining a simple assembly structure. Utility Model Content

[0003] The purpose of this invention is to provide an LED ceiling light with an anti-fall structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An LED ceiling light with an anti-fall structure includes a fixed base, a lampshade assembly, a light source module, a positioning bracket, and an anti-fall limiting structure. The fixed base is fixedly installed below the ceiling, the lampshade assembly covers the fixed base, and the light source module is disposed inside the fixed base. The positioning bracket is installed on the back of the light source module and connected to the fixed base via multiple positioning pins. The fixed base has insertion grooves that correspond to the positioning pins. The anti-fall limiting structure includes a limiting ring disposed on the inner wall of the lampshade assembly, an anti-detachment hook disposed on the outer edge of the positioning bracket, and a reverse limiting tongue that cooperates with the anti-detachment hook. The limiting ring is disposed along the inner circumference of the lampshade assembly. The anti-detachment hook automatically engages with the inner wall of the limiting ring after passing through the insertion groove during the insertion of the positioning bracket. The reverse limiting tongue is fixed to the lower inner edge of the limiting ring to prevent the anti-detachment hook from rebounding, forming a reverse anti-detachment structure.

[0006] Preferably, the limiting ring is a segmented arc-shaped structure, with each segment of the limiting ring having a reverse limiting tongue, and a maintenance buffer gap left between adjacent limiting tongues.

[0007] Preferably, the anti-detachment hook is an inverted hook structure that is wider at the top and narrower at the bottom, and its locking end face is provided with an inclined guide angle, which forms an inclined sliding guide cooperation with the locking edge of the limiting ring.

[0008] Preferably, the insertion groove is provided with a locking lug to limit the insertion depth of the positioning pin and prevent overtravel from causing the hook to misalign.

[0009] Preferably, the positioning bracket is a circular plate structure, with 3 to 5 sets of anti-detachment hooks and positioning pins evenly distributed radially on its outer edge.

[0010] Preferably, the lampshade assembly is connected to the fixed chassis by a rotating snap-fit ​​structure, and the assembly is completed within the range of 30° to 45° of rotation angle.

[0011] Preferably, the reverse limiting tongue is made of elastic polypropylene material and has a flexible buffer ridge at the tail to absorb the impact force during the insertion process.

[0012] Preferably, an elastic support pad is provided between the light source module and the positioning bracket to improve shock resistance and fit.

[0013] Preferably, the bottom of the lampshade assembly is provided with a transparent diffuser plate, which is fixed inside the lampshade assembly by a slot structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This LED ceiling light with an anti-fall structure uses a triple-coordinated structure of anti-detachment hook, limit ring, and reverse tongue to achieve "active anti-detachment" of the light source module throughout the entire process from installation to use, effectively preventing the risk of falling caused by vibration, accidental collision, or inverted installation.

[0016] 2. This LED ceiling light with an anti-fall structure uses a combination design of structural self-locking, inclined guide, and elastic buffer for all limiting components to ensure smooth installation and operation for users, while maintaining high-strength anti-fall performance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 As shown, this utility model provides an LED ceiling light with an anti-fall structure, including a fixed base (1), a lampshade assembly (2), a light source module (3), a positioning bracket (4), and an anti-fall limiting structure (5).

[0025] The fixed base (1) is a circular aluminum plate stamping structure with a diameter of Φ295mm and a thickness of 1.2mm. The base has multiple insertion slots (11) with a length of 15mm and a width of 5.2mm. At the end of each slot is a locking lug (12) with a height of 1.5mm and a slope angle of approximately 45°, used to limit and stop the positioning pin (41). The slot opening has a guide bevel with an angle of 20° to improve insertion smoothness.

[0026] The light source module (3) is an aluminum substrate COB light source, which is integrated with the driver board and connected to the positioning bracket (4) on the back by 4 screws. The positioning bracket (4) is an annular ABS plate with a diameter of Φ270mm and a thickness of 3.5mm. Four sets of pins and anti-detachment hooks are evenly distributed on the edge of the plate. The length of the pin (41) is 13mm. It is recommended to control the maximum insertion force at 8–12N. After being inserted into the slide, it forms a physical stop with the lug.

[0027] Each set of anti-detachment hooks (52) is arranged side by side with the pin. The hooks are 2.0mm thick, in the shape of barbs, wider at the top and narrower at the bottom. The snap-fit ​​end is provided with a guide angle (521) with a width of 3.5mm and a bevel angle of 20°, which is used to form a bevel guide interference fit with the limit ring (51). When it slides in, it automatically compresses and deforms, and after it is snapped in, it springs back and locks.

[0028] The limiting ring (51) is fixed to the inner wall of the lampshade assembly (2). The structure is a combination of four arc-shaped rings with an inner diameter of Φ260mm and an arc length of about 60° for each segment. A maintenance buffer gap of 5mm is provided between the segments. A reverse limiting tongue (53) is fixed below each limiting ring. The tongue is made of polypropylene material (PP, Shore hardness 65A) with a thickness of 1.2mm. The tail of the tongue is provided with a flexible buffer ridge with a height of 0.8mm and a width of 2mm, which can absorb the insertion impact and increase the pull-back resistance.

[0029] During the actual assembly process, users can follow these steps:

[0030] 1: Assemble the light source module (3) and the positioning bracket (4) into a whole module;

[0031] 2: Align with the insertion slot (11) on the chassis (1) and insert it vertically;

[0032] 3: The pin (41) slides into the groove and is limited at the end lug;

[0033] 4: The anti-detachment hook (52) passes through the slide groove and engages with the inner side of the limiting ring (51);

[0034] 5: The bottom of the hook is blocked and pulled back by the limiting tongue (53), realizing the reverse release limit;

[0035] 6: Rotate the lampshade assembly (2) clockwise 30°–45° and lock it to the outer edge of the chassis;

[0036] 7: Power on and the lights will illuminate, installation complete.

[0037] In the assembled state, if the user accidentally lifts, pulls lightly, or causes local displacement due to vibration, the hook and the tongue will still maintain a mechanical interference relationship to prevent the light source module from coming off. The tongue structure has been simulated and tested by 3D printing modeling and can withstand a pull-back force of ≥20N without deformation and recover ≥1000 times.

[0038] To enhance shock resistance, a silicone elastic pad (6) with a diameter of 260 mm and a thickness of 3 mm is provided between the light source module (3) and the positioning bracket (4). The compression stroke is controlled within 0.5 mm, providing good fit and shock absorption.

[0039] In addition, the lampshade assembly (2) has a high-transparency diffuser plate (7) at the bottom. The diffuser plate is made of PC-V2 flame-retardant material with a thickness of 1.0mm. It is installed by a slot structure with no less than 3 sets of protrusions and a snap-fit ​​depth of 4mm. It has the dual functions of uniform light output and anti-fall structure.

[0040] The overall structural design, while allowing for rapid assembly, forms a five-fold anti-detachment system consisting of snap-fit ​​guide, limit hook, tongue anti-pull-out, elastic buffer, and rotary locking. It is particularly suitable for indoor environments with high maintenance frequency and high safety requirements, such as hotels, hospitals, and subways.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
