[0020] Reference Figure 1A ceiling light includes: a lamp holder 100, a lamp shade 200, a connecting structure 900, and a mounting structure 600. The lamp holder 100 is equipped with a lamp assembly 500. The lamp shade 200 is installed on the lamp holder 100 and is light-transmitting. The lamp shade 200 has an inner cavity 230 and an opening 270. The inner cavity 230 can and can only be connected to the outside of the lamp shade 200 through the opening 270. The lamp assembly 500 passes through the opening 270 and extends into the inner cavity 230. The lamp holder 100 closes the opening 270. The lamp holder 100 is connected to the lamp shade 200 through the connecting structure 900. The mounting structure 600 is disposed on the lamp holder 100 and is used to install and fix the lamp holder 100. The lampshade 200 is designed to connect to the inner cavity 230 only through the opening 270. The lamp holder 100 only needs to close the opening 270, eliminating concerns about matching the shape of the lampshade 200. This achieves a universal connection between the lamp holder 100 and lampshades 200 of various shapes. This design greatly enhances the design freedom of the lampshade 200. Whether it is a traditional regular shape or an artistic irregular design, it can be easily adapted to the same lamp holder 100, providing lighting designers with a wide range of design possibilities and meeting consumers' needs for personalized and diverse lighting fixtures. At the same time, the structure of the lamp assembly 500 extending into the inner cavity 230 through the opening 270 and the lamp holder 100 closing the opening 270 ensures the sealing and safety of the lighting fixture, preventing the entry of foreign objects such as dust and moisture, and extending the service life of the lighting fixture. In terms of installation and maintenance, since the connection between the lamp holder 100 and the lamp shade 200 is no longer restricted by shape, replacing the lamp shade 200 becomes simple and quick. Users can easily replace the lamp shade 200 with different shapes according to their own preferences or changes in decoration style, without having to replace the entire lamp holder 100, which reduces usage costs and resource consumption, and improves the practicality and economy of the lamp.

[0021] In some embodiments, reference is made to Figure 2 The lampshade 200 is designed as a hollow disc, with an opening 270 located at the top and center of the lampshade 200. The lamp holder 100 is recessed relative to the side edges of the lampshade 200. The hollow structure of the disc-shaped lampshade 200 provides ample space for the lamp assembly 500, ensuring that light can be diffused evenly in all directions. This avoids light obstruction or uneven distribution caused by the irregular shape of the lampshade 200, improving lighting efficiency and light comfort. The centrally located opening 270 allows the lamp assembly 500 to extend into the inner cavity 230 of the lampshade 200 at the optimal angle, achieving precise light projection and effective utilization, and reducing light loss. The lamp holder 100 is recessed within the side edge of the lamp shade 200, avoiding direct contact between the lamp holder 100 and the side of the lamp shade 200. This reduces the risk of damage to the lamp shade 200 due to collisions or friction, enhances the durability and safety of the lamp, and also provides convenience for cleaning and maintenance of the lamp shade 200. Users can easily wipe the surface of the lamp shade 200 without worrying about interference from the lamp holder 100.

[0022] Furthermore, by combining multiple lamp groups 500, a uniform and bright lighting effect can be achieved. At the same time, the central opening 270 of the disc lamp shade 200 is designed to facilitate the installation of dimming devices or intelligent lighting modules, meeting the personalized lighting needs of different scenarios.

[0023] In some embodiments, reference is made to Figure 3 The lampshade 200 has a mounting platform 250 on its top. An opening 270 is located on and extends through the mounting platform 250. The lamp holder 100 is mounted on the mounting platform 250 via a connecting structure 900. The mounting platform 250 provides a clear fixed position and support platform for the lamp holder 100, making the connection between the lamp holder 100 and the lampshade 200 more secure and reliable. This reduces the risk of loosening or detachment due to improper installation, ensuring the safety of the luminaire during long-term use. Simultaneously, the tight fit between the mounting platform 250 and the lampshade 200 enhances the sealing performance of the luminaire, effectively preventing dust, insects, and other foreign objects from entering the lampshade 200, protecting the lamp assembly 500 from damage, and extending the luminaire's lifespan. In addition, this structural design simplifies the installation process of the lamps. Installers only need to align the lamp holder 100 with the mounting platform 250 and fix it in place. There is no need to find complicated mounting holes on the surface of the lamp cover 200 or perform tedious positioning operations, which improves installation efficiency and reduces installation costs.

[0024] In practical applications, the mechanical strength and stability of the mounting platform 250 can be enhanced by modifying its composition to withstand adverse environmental factors such as vibration and impact. For example, the mounting platform 250 can be manufactured using thickened metal materials, and anti-loosening washers or locking devices can be added at the connection between the mounting platform 250 and the lamp holder 100 to ensure reliable operation of the luminaire in harsh environments. Furthermore, the mounting platform 250 can also integrate an intelligent installation system. For instance, sensors can be embedded within the mounting platform 250 to monitor the installation status and operation of the luminaire in real time. When unstable installation or a malfunction is detected, an alarm can be promptly issued to the user, enabling intelligent management and maintenance of the luminaire.

[0025] In some embodiments, reference is made to Figure 3The mounting platform 250 and the lampshade 200 are integrated. The mounting platform 250 is bent from the edge of the opening 270 and protrudes relative to the top of the lampshade 200. This one-piece molding of the mounting platform 250, with its bent edge of the opening 270 and protrusion relative to the top of the lampshade 200, not only simplifies the manufacturing process of the lampshade 200 and reduces production costs, but also enhances the structural strength and stability of the mounting platform 250. The bending process makes the mounting platform 250 and the lampshade 200 an organic whole, avoiding the connection gaps and loosening problems caused by separate manufacturing and assembly, improving the integrity and sealing of the luminaire, ensuring the stability of the internal environment of the lampshade 200, and contributing to the normal operation and extended lifespan of the lamp assembly 500. Simultaneously, the protruding structure of the mounting platform 250 provides superior support and positioning conditions for the lamp holder 100, allowing the lamp holder 100 to be installed more precisely on the lampshade 200, reducing positional deviations during installation, and improving the assembly quality of the luminaire.

[0026] In practical implementation, the bending process and protrusion height can be adjusted according to the material of the lampshade 200 and the usage scenario. For metal lampshades 200, such as aluminum alloy lampshades 200, precision stamping and bending techniques can be used to achieve integrated molding of the mounting platform 250 and the lampshade 200. The bending points can be reinforced, such as by adding ribs or using special alloy materials, to improve the load-bearing capacity and deformation resistance of the mounting platform 250, making it suitable for the installation of large or heavy lighting fixtures. For plastic lampshades 200, injection molding can be used to directly form the structure of the mounting platform 250 during the molding process of the lampshade 200. By optimizing the mold design and material formula, the bonding strength between the mounting platform 250 and the lampshade 200 can be ensured. At the same time, anti-slip textures or patterns can be added to the surface of the mounting platform 250 as needed to enhance the anti-slip performance and decorative effect of the lighting fixture.

[0027] In some embodiments, reference is made to Figure 5The connecting structure 900 includes screws 950. Both the lamp holder 100 and the lamp shade 200 have through holes 290. The screws 950 pass through two through holes 290 and connect and fix the lamp holder 100 and the lamp shade 200. The screw 950 connection offers advantages such as high connection strength and reliability, effectively resisting various external forces generated during lamp use, such as vibration, wind load, and self-weight, ensuring a tight connection and stable fixation between the lamp holder 100 and the lamp shade 200, thus extending the lamp's lifespan. Simultaneously, the screw 950 connection is simple and convenient to install and disassemble, requiring no special tools or complex processes. Users can assemble, disassemble, and maintain the lamps themselves as needed, lowering the barrier to entry and maintenance costs, and improving the lamp's practicality. Furthermore, the standardized specifications and dimensions of the screw 950 allow lamp manufacturers to easily obtain compatible connectors, facilitating large-scale production, improving production efficiency, and reducing production costs. It also facilitates standardized design and modular assembly of lamps, improving production flexibility and product compatibility.

[0028] It is conceivable that the connecting structure 900 can also be composed of other components, such as connecting the lamp holder 100 and the lampshade 200 through clips, metal hooks, etc. The specific implementation method is not unique, but can be adjusted according to the actual situation, and is not limited here.

[0029] In some embodiments, reference is made to Figure 3 Multiple screws 950 are arranged around the opening 270. This design effectively solves the stress concentration problem that may occur with traditional single-screw connections, resulting in a more uniform force distribution between the lamp holder 100 and the lampshade 200, significantly enhancing the stability and reliability of the connection. This surrounding distribution ensures that the lampshade 200 is subjected to uniform tension in all directions, avoiding deformation or damage to the lampshade 200 due to uneven stress at a single point, extending the service life of the lampshade 200, and improving the overall structural strength of the lamp, making it better able to resist external impacts and vibrations, suitable for various complex and changing operating environments. In addition, the use of multiple screws 950 increases the redundancy of the connection. Even if individual screws 950 are accidentally damaged or loosened, the other screws 950 can still maintain a certain degree of connection, reducing the risk of the lamp falling off and improving safety during use.

[0030] During implementation, the number and position of screws 950 can be optimized according to the shape and size of the lampshade 200. For a circular lampshade 200, screws 950 can be evenly distributed around the circumference of the opening 270, such as by arranging 3, 4 or 6 screws 950 at equal intervals to form a symmetrical connection structure 900, ensuring that the lampshade 200 is subjected to uniform force. For a square lampshade 200, screws 950 can be distributed at equal intervals or in a specific symmetrical pattern around the opening 270, such as by placing screws 950 at the four corners and the midpoints of the sides, to adapt to the geometric characteristics of the square lampshade 200.

[0031] In some embodiments, reference is made to Figure 5 The connection structure 900 also includes a washer 930, which is located between the head of the screw 950 and the lamp holder 100. The washer 930 is elastic. The elasticity of the washer 930 can effectively buffer the pressure impact generated during the tightening of the screw 950, making the connection between the lamp holder 100 and the lamp cover 200 more stable, avoiding damage such as indentations and cracks on the surface of the lamp cover 200 due to excessive instantaneous pressure, and protecting the integrity of the lamp cover 200. Secondly, the washer 930 can maintain a certain elastic deformation after the screw 950 is tightened, thereby applying a continuous preload force to the connection between the lamp holder 100 and the lamp cover 200, compensating for loosening of the connection caused by factors such as temperature changes and material aging, ensuring the long-term reliability of the connection, and extending the service life of the lamp. In addition, the gasket 930 increases the sealing of the connection structure 900, effectively preventing dust, moisture and other foreign objects from entering the lamp through the gap between the screw 950 and the lamp holder 100, protecting the lamp assembly 500 and other internal components from damage, and improving the lamp's protective performance.

[0032] In practical implementation, different materials and performance of gaskets 930 can be selected according to the material of the lampshade 200 and the usage environment. For example, for glass lampshades 200, soft and highly elastic rubber gaskets 930 can be selected. Their good flexibility and compressive strength can effectively protect the glass surface from damage caused by the tightening force of screws 950. At the same time, rubber gaskets 930 also have certain waterproof and dustproof properties, which can meet the usage requirements in humid environments. For metal lampshades 200, metal spring gaskets 930 or composite material gaskets 930 can be used. These types of gaskets 930 have higher strength and elastic limit, can withstand greater tightening force, and maintain a stable elastic compensation effect during long-term use. They are suitable for some heavy-duty lamps that require high connection strength.

[0033] In some embodiments, reference is made to Figure 5The connecting structure 900 includes a protective ring 400 attached to the inner wall of the lampshade 200. A screw 950 passes sequentially through the lamp holder 100, the lampshade 200, and the protective ring 400. The protective ring 400, in conjunction with the head of the screw 950, tightly presses and secures the lamp holder 100 and the lampshade 200 together. The protective ring 400 significantly improves the connection stability of the lamp, the protection of the lampshade 200, and its service life. Firstly, the protective ring 400 fits tightly against the inner wall of the lampshade 200, evenly distributing pressure during the tightening of the screw 950. This prevents the lampshade 200 from deforming or cracking due to excessive localized stress. For some thin-walled lampshades 200 or lampshades 200 made of brittle materials such as ceramic or glass, it provides effective protection, ensuring the integrity and aesthetics of the lampshade 200. Secondly, the synergistic clamping action of the protective ring 400 and the screw 950 head enhances the friction and connection strength between the lamp holder 100 and the lamp cover 200, making the connection more secure and reliable. It can effectively resist various external forces, such as vibration and collision, that the lamp is subjected to during use, reducing the risk of the lamp holder 100 and the lamp cover 200 becoming loose and improving the safety of the lamp.

[0034] In practical applications, the protective ring 400 can be customized according to the material, shape, and usage requirements of the lampshade 200. For example, for a plastic lampshade 200, the protective ring 400 can be made of the same or similar plastic material as the lampshade 200, and injection molded to fit tightly against the inner wall of the lampshade 200, ensuring good sealing without damaging the lampshade 200. For a metal lampshade 200, the protective ring 400 can be made of corrosion-resistant metal or have its surface treated with rust prevention to meet the durability and long-term use requirements of the metal lampshade 200. In addition, the protective ring 400 can also integrate other functional components, such as setting a reflective coating or texture on the inside of the protective ring 400 to further optimize the light reflection effect of the lampshade 200 and improve the lighting efficiency of the lamp; or opening ventilation holes or heat dissipation grooves on the protective ring 400 to improve the heat dissipation conditions inside the lampshade 200, reduce the operating temperature of the lamp assembly 500, and extend the life of the lamp assembly 500.

[0035] In some embodiments, reference is made to Figure 2The mounting structure 600 includes a mounting base 800 and a snap-fit ​​bracket 700. The snap-fit ​​bracket 700 is disposed on the lamp holder 100, and the mounting base 800 has mounting holes for securing itself externally. The snap-fit ​​bracket 700 can snap onto the mounting base 800. The mounting base 800 is pre-installed on the ceiling or other supporting structure, providing a stable foundation for the lamp. The snap-fit ​​mechanism between the snap-fit ​​bracket 700 and the mounting base 800 allows the lamp holder 100 to be quickly and accurately connected to the mounting base 800 without the need for tedious tightening operations using screwdrivers or other tools, greatly shortening installation time, reducing installation difficulty, and improving installation efficiency and user experience. Furthermore, this mounting structure 600 is also easy to disassemble, facilitating subsequent maintenance, cleaning, and replacement of the lamp. Users can easily remove the lamp holder 100 for related operations as needed without worrying about damage or displacement of the mounting base 800, thus improving the maintainability and lifespan of the lamp.

[0036] Furthermore, the clip bracket 700 can be designed with anti-slip and anti-loosening functions, such as adding rubber pads or elastic teeth at the clip points, to ensure the stability of the connection between the lamp holder 100 and the fixing base 800, while facilitating one-handed installation and disassembly by the user. The clip bracket 700 can be designed with a modular structure, providing various specifications and models of clip bracket 700 according to the shape and size of the lamp, to achieve adaptable connection with different lamps.

[0037] In some embodiments, reference is made to Figure 4 The inner top wall of the lampshade 200 is coated with a reflective coating. This coating efficiently reflects the light emitted by the lamp assembly 500 to the space requiring illumination, minimizing light absorption and scattering losses within the lampshade 200. This improves light utilization, allowing the luminaire to provide brighter lighting at the same power, achieving energy conservation and emission reduction. Furthermore, by selecting reflective coatings of different colors and reflectivities, the light color and lighting atmosphere can be adjusted to suit different usage scenarios and user needs, providing a personalized lighting experience. In addition, the reflective coating softens and diffuses light to a certain extent, distributing it more evenly throughout the lighting area. This reduces glare and shadows caused by direct or uneven light reflection, improving lighting comfort and visual effects. This is particularly beneficial in places with high lighting quality requirements, such as art galleries and exhibition halls, where it better showcases the details and colors of exhibits and artworks.

[0038] In practical applications, appropriate reflective coating materials and processes can be selected according to different lighting needs and environmental characteristics. By precisely controlling the coating thickness and process parameters, a good reflection effect can be achieved while reducing energy consumption.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
