[0029] See also Figures 1 to 4 In the specific embodiment shown, the utility model discloses an anti-glare panel lamp structure, including: a lamp body 10, a reflective paper 20, a PCBA lamp board 30, a light guide plate 40 and a diffuser plate 50, the lamp body 10 is provided with a accommodating cavity, a stepped portion 11 is provided in the accommodating cavity, the reflective paper 20, the PCBA lamp board 30, the light guide plate 40 and the diffuser plate 50 are arranged in sequence from top to bottom, and the diffuser plate 50 is installed on the stepped portion 11, and the light emitted by the PCBA 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 emitted after being diffused.

[0030] Specifically, a deep anti-glare effect is achieved through the combined design of the stepped portion 11, the reflective paper 20, the light guide plate 40 and the diffuser plate 50 inside the lamp body 10. This design enables the light emitted by the PCBA lamp board 30 to first be reflected by the light guide plate 40, then reflected by the reflective paper 20 to the diffuser plate 50, and then emitted after diffusion. In this process, the propagation path of the light is effectively controlled and optimized, avoiding the glare phenomenon caused by direct and reflected light, that is, avoiding the problem of eye glare causing discomfort to the human body when looking up at the light source, and having strong practicality. In addition, due to multiple reflections and diffusions, the light becomes more uniform and soft, thereby providing a comfortable and non-glaring lighting environment, which is particularly important for people who work or study under the lamp for a long time, and can effectively reduce eye discomfort and fatigue. In addition, components such as the reflective paper 20, PCBA lamp board 30, light guide plate 40 and diffuser plate 50 are cleverly integrated into the accommodating cavity of the lamp body 10, making the entire structure compact and efficient. This design not only saves space, but also improves the utilization rate of light energy, achieving the goal of energy saving and environmental protection.

[0031] In one embodiment, the PCBA lamp board 30 includes a soft lamp board and a number of LED lamp beads, and the number of LED lamp beads are evenly distributed on the side of the soft lamp board.

[0032] Specifically, by evenly distributing the LED lamp beads on the sides of the flexible light board, rather than the traditional top or bottom, space can be used more efficiently, especially in lighting equipment that requires a compact design. This layout allows more LED lamp beads to be integrated in a smaller area, thereby increasing the lighting intensity without increasing the overall size. In addition, the side-distributed LED lamp beads can achieve a side-lighting effect, which is very useful in certain specific application scenarios. For example, it can be used as a backlight source, decorative lighting or indicator light, providing uniform and soft side light to enhance the visual effect. In addition, the side-arranged LED lamp beads make the design of the PCBA light board 30 more flexible, and the number, spacing and angle of the LED lamp beads can be adjusted according to actual needs to achieve different lighting effects and layout requirements.

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

[0034] In one embodiment, a cover plate 60 is further disposed on the top of the lamp body 10 , and a folded edge 61 is extended downward from the edge of the cover plate 60 , and the folded edge 61 is used to wrap the edge of the lamp body 10 .

[0035] Specifically, the design of the folded edge 61 allows it to tightly wrap around the edge of the lamp body 10, forming a closed structure, which can effectively prevent light from leaking out from the back or edge of the lamp body 10, which is the so-called "back light leakage" phenomenon. Back light leakage not only causes a waste of light energy, but also may cause unnecessary interference or discomfort to the user. In addition, since the folded edge 61 can prevent back light leakage, more light can be used and directed to the area that needs to be illuminated, thereby improving the luminous flux of the panel light. At the same time, this also improves the light efficiency, allowing the lamp to provide brighter and more uniform lighting effects at the same energy consumption. In addition, the design of the folded edge 61 is not only functional, but also can enhance the aesthetics of the lamp. It can make the edge of the lamp smoother and neater, and enhance the overall visual effect. In addition, the folded edge 61 can also prevent users or objects from contacting the electrical components inside the lamp body, thereby improving the safety of the lamp.

[0036] In one embodiment, the cover plate 60 is further provided with an inner recess 62 .

[0037] Specifically, the cover plate 60 is provided with an inner recess 62 downward, which plays a role similar to a reinforcing rib. The inner recess 62 can enhance the structural strength and rigidity of the cover plate 60. This design can improve the overall stability of the cover plate 60 without increasing the thickness or weight of the material, and prevent deformation or damage caused by external forces. In addition, the design of the inner recess 62 can optimize the stress distribution on the cover plate 60. When subjected to external forces, the stress can be more evenly dispersed to the entire cover plate 60, avoiding damage caused by excessive local stress.

[0038] In one embodiment, a mounting portion 63 is further provided at the edge of the cover plate 60 , and a connecting column 12 corresponding to the mounting portion 63 is provided on the lamp body 10 .

[0039] Specifically, the edge of the cover plate 60 is provided with a plurality of mounting portions 63 similar to ears, and then the mounting portions 63 are fixed to the connecting column 12 by screws, that is, the mounting portions 63 cooperate with the connecting column 12 and are fixed by screws, thereby ensuring a firm connection between the cover plate 60 and the lamp body 10. This connection method can effectively prevent the cover plate 60 from loosening or falling off during use, thereby improving the stability and safety of the lamp. In addition, the design of the mounting portions 63 and the connecting column 12 allows for precise alignment during the assembly process, which ensures that the cover plate 60 can be accurately installed on the lamp body 10, thereby avoiding installation problems caused by position deviation.

[0040] In one embodiment, a foam piece 70 is further disposed between the reflective paper 20 and the cover plate 60 , and the foam piece 70 is made of EVA material.

[0041] Specifically, EVA foam is a porous polymer material, and its pores are filled with air, which gives it good buffering performance. When the lamp is subjected to external impact or vibration, the foam piece 70 can absorb and disperse these impact forces, thereby protecting the reflective paper 20 from damage. In addition, the buffering process of the foam can be subdivided into an initial contact stage, a deformation stage, and a recovery stage; in the initial contact stage, the foam piece 70 forms contact with the impact object; in the deformation stage, the foam begins to deform and absorb energy; in the recovery stage, when the impact force disappears, the foam will quickly return to its original state. In addition, by arranging the foam piece 70 between the reflective paper 20 and the cover plate 60, the structural stability of the entire lamp can be enhanced. The foam piece 70 can effectively prevent direct contact between the reflective paper 20 and the cover plate 60, and avoid mutual friction and damage caused by vibration or impact.

[0042] In one embodiment, the stepped portion 11 is located in the upper end region of the accommodating cavity.

[0043] Specifically, the step portion 11 is located in the area of ​​two-thirds to three-quarters of the overall height of the accommodating cavity to achieve a deeper anti-glare design. In addition, the design of the step portion 11 allows the light to be refracted and scattered multiple times when emitted, reducing the intensity of the light directly emitted to the human eye, effectively reducing the occurrence of glare. This design is particularly suitable for occasions that require high-brightness lighting but require glare avoidance, such as offices, libraries, etc. In addition, the design of the step portion 11 can also optimize the lighting effect. By adjusting the shape and size of the step portion 11, the distribution and projection range of the light can be controlled to achieve a more uniform and soft lighting effect.

[0044] In one embodiment, the lamp body 10 is further provided with a plurality of heat dissipation protrusions 13 at intervals.

[0045] Specifically, the design of the heat dissipation protrusion 13 significantly increases the surface area of ​​the lamp body 10, thereby increasing the contact area with the surrounding air, which helps to effectively transfer the heat generated inside the lamp body 10 to the external environment through heat convection and heat radiation, thereby achieving rapid heat dissipation. In addition, according to the principle of the heat dissipation protrusion 13, when heat is generated inside the lamp body 10, the heat will be transferred to the heat dissipation protrusion 13, and then transferred to the air or other media through the contact surface between the heat dissipation protrusion 13 and the surrounding environment. The presence of the heat dissipation protrusion 13 can greatly promote this process, thereby improving the heat dissipation efficiency. In addition, through the effective heat dissipation of the heat dissipation protrusion 13, the temperature of the lamp body 10 and its internal electrical components can be significantly reduced, avoiding problems such as performance degradation, accelerated aging, and even equipment damage caused by high temperature, which helps to maintain the stability and reliability of the equipment and extend its service life.

[0046] In one embodiment, spring clips 80 are further disposed on both sides of the lamp body 10 .

[0047] Specifically, one end of the spring clip 80 is connected to the lamp body 10, and the other end is used to clamp the external structure (e.g., wooden board) to complete the installation and fixation of the panel lamp. In addition, the elastic design of the spring clip 80 enables it to generate a certain clamping force when clamping the external structure, thereby ensuring a stable connection between the panel lamp and the mounting surface. This stability not only improves the safety of the lamp, but also avoids potential dangers caused by loosening or falling off. In addition, the design of the spring clip 80 has certain flexibility and adaptability, and can be applied to mounting surfaces of different materials, shapes and thicknesses. This design enables the panel lamp to be widely used in various occasions, such as homes, offices, commercial places, etc. In addition, when the panel lamp needs to be repaired or replaced, the lamp can be easily removed from the mounting surface by operating the spring clip 80. This design simplifies the maintenance and replacement process and reduces maintenance costs.

[0048] In one embodiment, this embodiment is different from the installation method of the spring clip 80, and installation components are also provided on both sides of the lamp body 10, and the installation components include a connecting plate, a clamping plate and a torsion spring. The connecting plate is slidably connected to the lamp body 10, and the top of the connecting plate and the clamping plate are hinged by a pin shaft. The torsion spring member is sleeved on the pin shaft, and one end of the torsion spring member is connected to the connecting plate, and the other end is connected to the clamping plate.

[0049] Specifically, the position of the connecting plate on the lamp body 10 can be adjusted by sliding according to the installation requirements, and then the connecting plate can be fastened to the lamp body 10 by screws. In addition, the installation assembly can flexibly adjust the position of the entire assembly to adapt to different installation environments through the sliding connection design of the connecting plate and the lamp body 10. This design greatly simplifies the installation and disassembly process and improves work efficiency. In addition, the clamping plate and the connecting plate are hinged by a pin shaft, and the torsion spring member is sleeved on the pin shaft, one end of which is connected to the connecting plate and the other end is connected to the clamping plate. This structure enables the clamping plate to automatically clamp or release the external structure (for example, a wooden board) under the action of the torsion spring member. This clamping method is stable and reliable, and can ensure a stable connection between the lamp body 10 and the external structure. In addition, the torsion spring member, as a mechanical component that works by utilizing the elasticity and structural characteristics of the material, can provide an adaptive clamping force during the clamping process, which means that no matter how the size or shape of the external structure changes, the installation assembly can adapt through the elastic deformation of the torsion spring member and always maintain a stable clamping force. In addition, the design of the mounting assembly not only takes into account the convenience of installation and the stability of clamping, but also takes into account the stability of the entire lighting system. Through the stable connection between the mounting assemblies on both sides and the external structure, the lamp body 10 can be effectively prevented from shaking or tilting during use, ensuring the stability and reliability of the lighting effect. In addition, the design of this mounting assembly has a wide range of applicability and can be applied to different installation environments and external structures. Whether it is a wall, a bracket or other forms of mounting points, as long as the clamping requirements of the mounting assembly can be met, the lamp body 10 can be easily installed stably.

[0050] 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 protection scope of the present invention.
