[0029] See also Figures 1 to 4 In the specific embodiment shown, the present invention discloses a ceiling lamp structure with a stepped shape, including: a lamp body 10, reflective paper 20, an FPCB lamp board 30, a light guide plate 40 and a diffuser plate 50. The lamp body 10 extends downward with a stepped portion 11, and the stepped portion 11 is provided with an annular storage cavity. The FPCB lamp board 30 is mounted on the side wall of the stepped portion 11. The reflective paper 20, the light guide plate 40 and the diffuser plate 50 are arranged in the annular storage cavity from top to bottom. The light emitted by the FPCB lamp board 30 is reflected by the light guide plate 40 to the reflective paper 20, and then reflected by the reflective paper 20 to the diffuser plate 50, where it is diffused and emitted.

[0030] Specifically, a step portion 11 extends downward through the lamp body 10, and the step portion 11 is provided with an annular storage cavity. The FPCB lamp board 30 is installed on the side wall of the step portion 11, and the reflective paper 20, the light guide plate 40 and the diffuser plate 50 are arranged in the annular storage cavity from top to bottom. The light emitted by the FPCB lamp board 30 is reflected by the light guide plate 40 to the reflective paper 20, and then reflected by the reflective paper 20 to the diffuser plate 50 and diffused before being emitted. That is, a step is added to the flat lamp body 10 to form a three-dimensional design, making the structural design simple and stylish, adapting to current market demand, and highly practical. Furthermore, by designing a stepped portion 11 on the lamp body 10 and providing an annular storage cavity, the reflective paper 20, light guide plate 40, and diffuser plate 50 are arranged sequentially from top to bottom, achieving multiple reflections and diffusion of light. Light emitted from the FPCB lamp board 30 is first guided by the light guide plate 40 and reflected onto the reflective paper 20. The reflective paper 20 then evenly reflects the light onto the diffuser plate 50. Finally, the diffuser plate 50 allows the light to be emitted softly and evenly. This process effectively improves the uniformity and diffusion of light, avoiding glare and spotlight caused by direct light, and making lighting more comfortable. Furthermore, adding a stepped design to the flat lamp body 10 not only optimizes the internal structural layout but also gives the lamp a unique aesthetic. This design allows the lamp to serve as a part of interior decoration while providing lighting, enhancing the overall design and fashion sense of the space and satisfying the modern consumer's pursuit of home aesthetics. In addition, as consumers' requirements for the quality of their home environment increase, lamps are no longer just lighting tools, but also an important part of home decoration. This step-shaped ceiling lamp has a simple and stylish structure design, which meets the current market demand for the beauty, practicality and innovation of lighting products, and helps to enhance the market competitiveness of products.

[0031] In one embodiment, the FPCB light board 30 includes a ring-shaped hard light board and a number of LED lamp beads, and the number of LED lamp beads are evenly distributed on the inner side of the hard light board, and the hard light board is mounted on the inner wall of the step portion 11.

[0032] Specifically, by evenly distributing a number of LEDs within the ring-shaped rigid light panel, an efficient light source layout is achieved. This layout not only ensures uniform light distribution but also improves light energy utilization efficiency, allowing the lamp to provide sufficient illumination while reducing energy waste. Furthermore, the tight fit between the ring-shaped rigid light panel and the inner wall of the stepped portion 11 contributes to a simpler and more streamlined overall design. Furthermore, the even distribution of the LEDs also avoids the appearance of light spots and dark areas, enhancing the visual effect and aesthetics of the lamp.

[0033] Among them, the hard light board adopts existing public technology, which will not be elaborated in detail here.

[0034] In one embodiment, a cover plate 60 is further provided on the top of the lamp body 10 , and the cover plate 60 is connected to the lamp body 10 .

[0035] Specifically, the primary function of the cover 60 is to protect the components within the lamp body 10, such as the FPCB 30, LEDs, reflective paper 20, light guide plate 40, and diffuser 50. These components are crucial to the proper operation of the lamp, but they are also relatively fragile and susceptible to environmental influences such as dust, moisture, and insects. The cover 60 effectively isolates these external factors, thereby extending the lamp's service life. Furthermore, the presence of the cover 60 improves the safety of the lamp by preventing users or maintenance personnel from directly contacting live parts within the lamp, reducing the risk of electric shock. Furthermore, in certain environments, such as humid or dusty ones, the cover 60 can also prevent fires caused by short circuits or component damage. Furthermore, the cover 60 provides a certain degree of dust and water resistance. In environments where dust and water resistance is required, such as kitchens and bathrooms, the cover 60 effectively prevents dust and moisture from entering the lamp, protecting it from damage.

[0036] In one embodiment, the cover plate 60 is further connected to a power module 70 , and the power module 70 is electrically connected to the FPCB light board 30 .

[0037] Specifically, the main function of the power module 70 is to convert the input power (such as alternating current (AC) or direct current (DC)) into stable power suitable for use by the FPCB lamp board 30 and the LED lamp beads thereon. This conversion ensures that the LED lamp beads can operate under stable voltage and current, thereby extending their service life and improving the lighting effect. In addition, the power module 70 usually has multiple protection functions, such as overvoltage protection, overcurrent protection, short circuit protection, etc. These protection functions can quickly cut off the power supply or reduce the output power when an abnormality occurs in the circuit, thereby protecting the FPCB lamp board 30, LED lamp beads and other related circuit components from damage. In addition, by connecting the power module 70 to the cover plate 60 and directly electrically connecting it to the FPCB lamp board 30, the overall design and installation process of the lamp are simplified. This design reduces the number of wires and connection points, reduces the failure rate, and improves the reliability and stability of the lamp.

[0038] Among them, the power module 70 is used to connect to the mains power, and the power module 70 includes but is not limited to Bluetooth, WiFi or 2.4G models to achieve communication connection with smart devices, so that the ceiling light can be controlled to turn on or off or adjust the color temperature through the smart device.

[0039] In one embodiment, an EVA foam member 70 is further provided between the cover plate 60 and the reflective paper 20 .

[0040] Specifically, EVA foam is a porous polymer material filled with air, giving it excellent cushioning properties. When the lamp is subjected to external impact or vibration, the foam absorbs and disperses the impact force, thereby protecting the reflective paper 20 from damage. Furthermore, the foam's cushioning process can be subdivided into an initial contact phase, a deformation phase, and a recovery phase. During the initial contact phase, the foam comes into contact with the impacting object; during the deformation phase, the foam begins to deform and absorb energy; and during the recovery phase, when the impact force dissipates, the foam quickly returns to its original shape. Furthermore, by placing the foam between the reflective paper 20 and the cover plate 60, the structural stability of the entire lamp is enhanced. The foam effectively prevents direct contact between the reflective paper 20 and the cover plate 60, preventing friction and damage caused by vibration or impact.

[0041] In one embodiment, the cover plate 60 is further provided with a compression strip 61 toward the EVA foam member 70 .

[0042] Specifically, the tight contact between the compression strip 61 and the EVA foam element 70 further ensures the lamp's internal sealing. The EVA foam element 70 itself has a certain sealing performance, but this sealing effect may weaken due to long-term use or external factors (such as temperature changes and vibration). The design of the compression strip 61 can provide additional pressure, making the EVA foam element 70 fit more tightly against the reflective paper 20, thereby preventing external impurities such as dust and moisture from entering the lamp interior, keeping the lamp clean and dry. In addition, the compression strip 61 not only enhances the sealing performance, but also improves the stability of the lamp's internal structure by its compression effect on the EVA foam element 70. During the use of the lamp, various factors may cause the internal components to move slightly or loosen. The presence of the compression strip 61 effectively limits this movement, ensuring the relative position of the internal components of the lamp is stable, and preventing performance degradation or damage caused by loose components.

[0043] In one embodiment, the cover plate 60 is further connected to a dip switch 90 , and the dip switch 90 is electrically connected to the FPCB light board 30 .

[0044] Specifically, the DIP switch 90 is used to adjust the color temperature, and it has five color temperature settings. Users can easily adjust the color temperature of the lamp according to different usage scenarios and needs. For example, in situations where a warm atmosphere is needed, a lower color temperature setting can be selected, while in environments requiring bright lighting, a higher color temperature setting can be selected. Furthermore, by directly operating the DIP switch 90, users can see the changes in color temperature in real time, allowing them to quickly adjust to a desired lighting effect. This instant feedback adjustment method greatly enhances the user experience. Furthermore, different usage scenarios have different color temperature requirements. For example, home lighting may require a soft warm white light, while commercial displays may require bright cool white light. The multi-level color temperature adjustment function of the DIP switch 90 allows the same lamp to adapt to a variety of usage scenarios, improving the lamp's practicality and applicability. Furthermore, compared to solutions that require purchasing multiple lamps with different color temperatures, the color temperature adjustment design using the DIP switch 90 allows users to purchase only one lamp to meet diverse color temperature needs, thus saving purchase costs.

[0045] In one embodiment, a mounting cavity 62 is further provided on the top of the cover plate 60 , and a mounting bracket 100 is connected to the mounting cavity 62 .

[0046] Specifically, the design of the mounting cavity 62 provides a stable interface for the mounting bracket 100, so that the mounting bracket 100 can be firmly connected to the cover plate 60, thereby ensuring that the entire ceiling lamp can be stably installed on the ceiling. In addition, the mounting bracket 100 generally has a high load-bearing capacity and can bear the weight of the ceiling lamp and its accessories, ensuring that it will not loosen or fall off during long-term use. In addition, through the standardized design of the mounting cavity 62 and the mounting bracket 100, users can more conveniently install the ceiling lamp to the specified position. This design reduces the errors and inconveniences that may occur during the installation process and improves the installation efficiency. In addition, with the support of the mounting bracket 100, the replacement and maintenance of the ceiling lamp also becomes simpler; when the lamp needs to be repaired or replaced, the user can easily remove the lamp from the mounting bracket 100, perform the corresponding operations, and then reinstall it.

[0047] In one embodiment, a rotation protrusion 63 is provided in the installation cavity 62 , and the installation bracket 100 is provided with a rotation groove 101 corresponding to the rotation protrusion 63 .

[0048] Specifically, through the corresponding design of the rotating protrusion 63 and the rotating groove 101, the user only needs to align the rotating groove 101 of the mounting bracket 100 with the rotating protrusion 63 in the mounting cavity 62, and then rotate the mounting bracket 100 to achieve quick installation. This design greatly simplifies the installation process and improves installation efficiency. Similarly, when the ceiling lamp needs to be removed, the user only needs to rotate the cover 60 to easily remove the ceiling lamp from the ceiling without using additional tools or performing complicated operations. In addition, the cooperation between the rotating protrusion 63 and the rotating groove 101 forms a rotation locking mechanism; when the mounting bracket 100 is rotated into place, the rotating protrusion 63 will snap into the rotating groove 101, thereby ensuring a secure connection between the mounting bracket 100 and the mounting cavity 62. This design can effectively prevent the ceiling lamp from loosening or falling off during use. In addition, the design of the rotating protrusion 63 and the rotating groove 101 can also disperse the weight and force of the ceiling lamp to a certain extent, making the connection between the mounting bracket 100 and the mounting cavity 62 more secure and reliable.

[0049] Preferably, mounting bracket 100 is circular and has mounting holes. A circular structure offers greater mechanical stability, evenly distributing forces and reducing stress concentration. Therefore, designing mounting bracket 100 in a circular shape makes it more stable during installation, making it less susceptible to deformation or loosening. Furthermore, the mounting holes not only facilitate installation but also allow fasteners such as bolts and screws to connect to the ceiling or other fixed structure, further strengthening the connection between mounting bracket 100 and the fixed structure and increasing its overall load-bearing capacity.

[0050] In one embodiment, the cavity bottom plate of the annular storage cavity is tilted upward from the outside to the inside, and a number of support protrusions 12 extend upward from the cavity bottom plate, and the diffusion plate 50 abuts against the support protrusions 12 .

[0051] Specifically, the design of the cavity bottom plate tilting from the outside to the inside can guide the light to propagate in a specific direction, reducing the disordered reflection and scattering of light inside the cavity. This design helps to ensure that the light can be emitted more effectively through the diffuser plate 50, rather than leaking inside the cavity. In addition, the design of the support protrusions 12 enables the diffuser plate 50 to tightly abut against these protrusions, forming an effective sealing structure. This sealing structure can further prevent light from leaking out of the gap between the cavity and the diffuser plate 50, ensuring the effective use of light. In addition, the main function of the diffuser plate 50 is to evenly distribute the light. With the support of the support protrusions 12, the diffuser plate 50 can maintain a stable position, and its surface can more evenly receive the light from the inside of the cavity, which helps to improve the uniformity of the light, making the lighting effect softer and more comfortable.

[0052] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
