[0001] This utility model relates to the field of lighting technology, and in particular to a waterproof side-emitting panel light. Background Technology

[0002] In the modern lighting market, panel lights are widely used in various indoor and outdoor locations, such as commercial spaces, home environments, and outdoor advertising facilities, due to their slim and aesthetically pleasing design and uniform light distribution. However, existing panel lights have several problems in practical applications. First, their waterproof performance is poor. In high-humidity indoor environments (such as bathrooms and kitchens) or complex and variable outdoor environments, moisture can easily seep into the lamp body, causing short circuits and damage to electronic components. This not only affects the normal functioning of the lighting but also significantly shortens the lifespan of the panel light. Second, their structural design is not reasonable enough. The assembly and disassembly process of traditional panel lights is cumbersome, increasing installation and maintenance costs. Third, in terms of luminous effect, some traditional panel lights suffer from uneven light distribution and insufficient brightness, making it difficult to meet diverse lighting needs. Therefore, developing a panel light with excellent waterproof performance, a robust structure, and good luminous effect is of significant practical importance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a waterproof side-emitting panel light, which can effectively solve the problems of poor waterproof performance, inconvenient installation and disassembly, and unsatisfactory luminous effect of existing panel lights, improve the reliability, practicality and applicability of panel lights, and meet the lighting needs of different scenarios.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A waterproof side-emitting panel light includes a face frame, a light guide assembly, a backlight assembly, a first sealing strip, and a light source assembly. The backlight assembly includes a back plate, a pressure strip frame, and a buffer layer. The pressure strip frame is used to press the light guide assembly, the buffer layer, and the back plate into the face frame. The light source assembly is disposed on one side of the light guide assembly.

[0006] The face frame includes four frame strips connected end to end. Each frame strip has a serrated groove and a first groove extending along its length. The serrated groove is used to lock the pressure strip frame and the back plate. The first groove is used to embed a first sealing strip. The first sealing strip is located outside the light guide assembly, the buffer layer and the back plate. The pressure strip frame squeezes the first sealing strip to achieve waterproofing and sealing of the panel light.

[0007] Furthermore, the two inner walls of the serrated groove are provided with serrated locking protrusions.

[0008] Furthermore, the first grooves on the four frame strips form an annular groove surrounding the inner side of the face frame.

[0009] Furthermore, the first sealing strip has a first strip-shaped protrusion extending along the length direction of the first sealing strip on one end face near the pressure strip frame.

[0010] Furthermore, there are two first strip-shaped protrusions, which are located at opposite ends of one end face of the first sealing strip and are spaced apart.

[0011] Furthermore, it also includes a second sealing strip, and the frame strip is provided with a second groove extending along the length direction. The second groove is used to embed the second sealing strip, and the light guide assembly is pressed against the second sealing strip to achieve waterproofing and sealing of the panel light.

[0012] Furthermore, the first groove is located between the serrated groove and the second groove, and the position of the first groove is higher than the position of the second groove.

[0013] Furthermore, a second strip-shaped protrusion extending along the length direction of the second sealing strip is provided on one end face of the second sealing strip near the back plate.

[0014] Furthermore, there are two second strip-shaped protrusions, which are located at opposite ends of one end face of the second sealing strip and are spaced apart.

[0015] Furthermore, the depth of the serrated groove is greater than the depth of the first groove.

[0016] The beneficial effects of this utility model are as follows:

[0017] This solution organically combines the face frame, light guide assembly, backlight assembly, first sealing strip, and light source assembly to construct a complete and efficient panel light structure system. The pressure strip frame firmly presses the light guide assembly, buffer layer, and back plate into the face frame, forming a stable internal structure. The buffer layer effectively buffers external pressure, protecting internal components from damage. The light source assembly is located on one side of the light guide assembly, achieving a side-emitting effect. This allows light to be evenly diffused through the light guide assembly, resulting in softer and more uniform light compared to traditional direct light emission, reducing glare and improving lighting quality. At the same time, the serrated grooves on the frame facilitate quick installation and removal of the pressure strip frame and back plate, improving installation and maintenance efficiency. The first sealing strip embedded in the first groove, under the pressure of the pressure strip frame, tightly fits the gaps between the components, forming an effective waterproof barrier to prevent moisture intrusion and ensure stable operation of the panel light in humid environments.

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figures 1 to 5 A waterproof side-emitting panel light includes a face frame, a light guide assembly, a backlight assembly, a first sealing strip, and a light source assembly. The backlight assembly includes a back plate, a pressure strip frame, and a buffer layer. The pressure strip frame is used to press the light guide assembly, the buffer layer, and the back plate into the face frame. The light source assembly is disposed on one side of the light guide assembly.

[0027] The face frame includes four frame strips connected end to end. Each frame strip has a serrated groove and a first groove extending along its length. The serrated groove is used to lock the pressure strip frame and the back plate. The first groove is used to embed a first sealing strip. The first sealing strip is located outside the light guide assembly, the buffer layer and the back plate. The pressure strip frame squeezes the first sealing strip to achieve waterproofing and sealing of the panel light.

[0028] As can be seen from the above description, the beneficial effects of this utility model are as follows:

[0029] This solution organically combines the face frame, light guide assembly, backlight assembly, first sealing strip, and light source assembly to construct a complete and efficient panel light structure system. The pressure strip frame firmly presses the light guide assembly, buffer layer, and back plate into the face frame, forming a stable internal structure. The buffer layer effectively buffers external pressure, protecting internal components from damage. The light source assembly is located on one side of the light guide assembly, achieving a side-emitting effect. This allows light to be evenly diffused through the light guide assembly, resulting in softer and more uniform light compared to traditional direct light emission, reducing glare and improving lighting quality. At the same time, the serrated grooves on the frame facilitate quick installation and removal of the pressure strip frame and back plate, improving installation and maintenance efficiency. The first sealing strip embedded in the first groove, under the pressure of the pressure strip frame, tightly fits the gaps between the components, forming an effective waterproof barrier to prevent moisture intrusion and ensure stable operation of the panel light in humid environments.

[0030] Furthermore, the two inner walls of the serrated groove are provided with serrated locking protrusions.

[0031] As can be seen from the above description, the serrated protrusions on the two opposite inner walls of the serrated groove significantly increase the friction between the pressure strip frame and the back plate, making the connection more secure and reliable. During long-term use, it can effectively prevent the components from loosening due to factors such as vibration and external impact, enhance the overall stability of the panel light structure, and extend the service life of the product.

[0032] Furthermore, the first grooves on the four frame strips form an annular groove surrounding the inner side of the face frame.

[0033] As described above, the first groove on the four frame strips forms an annular groove around the inner side of the face frame, allowing the first sealing strip to completely surround the internal components of the panel light, forming a continuous and sealed waterproof space, effectively preventing moisture from seeping in from the face frame joints. Compared with the non-annular sealing structure, this design significantly improves waterproof performance and provides a more reliable guarantee for the stable operation of the panel light in humid environments.

[0034] Furthermore, the first sealing strip has a first strip-shaped protrusion extending along the length direction of the first sealing strip on one end face near the pressure strip frame.

[0035] As can be seen from the above description, the first strip-shaped protrusion on the end face of the first sealing strip near the pressure strip frame can better fill the gap when the pressure strip frame squeezes the first sealing strip, further enhancing the sealing effect; its design extending along the length of the sealing strip ensures good sealing throughout the entire length of the sealing strip, effectively preventing water vapor from entering and improving the waterproof performance of the panel light.

[0036] Furthermore, there are two first strip-shaped protrusions, which are located at opposite ends of one end face of the first sealing strip and are spaced apart.

[0037] As can be seen from the above description, setting two first strip protrusions with a certain distance between them can more effectively prevent water vapor from entering the lamp body through the gap compared to a single strip protrusion. When subjected to pressure, the gap between the two strip protrusions can produce elastic deformation, better adapting to different pressure conditions and gap changes, further improving waterproof and sealing performance, and enhancing the waterproof reliability of the panel light in complex environments.

[0038] Furthermore, it also includes a second sealing strip, and the frame strip is provided with a second groove extending along the length direction. The second groove is used to embed the second sealing strip, and the light guide assembly is pressed against the second sealing strip to achieve waterproofing and sealing of the panel light.

[0039] As described above, the addition of a second sealing strip, and the waterproof seal achieved by the compression between the back plate and the second sealing strip, forms a double waterproof structure. This design greatly improves the waterproof performance of the panel light. Even if the first sealing strip fails partially or is not sealed properly, the second sealing strip can still play a waterproof role, effectively preventing water vapor intrusion, greatly enhancing the reliability and stability of the product, and is especially suitable for outdoor environments or humid places with extremely high waterproof requirements.

[0040] Furthermore, the first groove is located between the serrated groove and the second groove, and the position of the first groove is higher than the position of the second groove.

[0041] As can be seen from the above description, the first groove is located between the serrated groove and the second groove, and is positioned higher than the second groove. This layout design requires water vapor to pass through more obstacles and paths during the infiltration process, increasing the difficulty for water vapor to enter the lamp body and further improving the waterproof effect. At the same time, the reasonable position distribution is conducive to the installation and cooperation between various components, making the structure of the entire panel light more compact and reasonable, and improving the product's assembly efficiency and structural stability.

[0042] Furthermore, a second strip-shaped protrusion extending along the length direction of the second sealing strip is provided on one end face of the second sealing strip near the back plate.

[0043] As described above, the second strip-shaped protrusion on the end face of the second sealing strip near the back panel can better fill the gaps when the back panel squeezes the second sealing strip, enhance the sealing effect, effectively block moisture, further improve the waterproof performance of the panel light, and ensure that the double waterproof structure plays its best role.

[0044] Furthermore, there are two second strip-shaped protrusions, which are located at opposite ends of one end face of the second sealing strip and are spaced apart.

[0045] As can be seen from the above description, the setting of two second strip-shaped protrusions with a certain distance between them further enhances the waterproof capability of the second sealing strip. Together with the double protrusion design of the first sealing strip, they form a more efficient and reliable waterproof sealing system, which can prevent water vapor from entering in all directions and at multiple levels, ensuring that the panel light can effectively prevent water vapor from seeping in under various harsh environments and ensuring the safe operation of internal components.

[0046] Furthermore, the depth of the serrated groove is greater than the depth of the first groove.

[0047] As described above, the depth of the serrated groove is greater than that of the first groove. This design allows the serrated groove to provide sufficient space for the pressure strip frame and the back panel, ensuring a stable connection after installation without any shaking or loosening. At the same time, this design does not affect the normal installation and sealing effect of the first sealing strip, achieving a good balance between structural strength and waterproof performance, ensuring that the panel light has a stable structure while possessing excellent waterproof performance.

[0048] Please refer to Figures 1 to 5 As shown, Embodiment 1 of this utility model is as follows:

[0049] Please refer to Figures 1 to 5 A waterproof side-emitting panel light includes a face frame 1, a light guide assembly 2, a backlight assembly 3, a first sealing strip 4, and a light source assembly 5. The backlight assembly 3 includes a back plate 31, a pressure strip frame 32, and a buffer layer 33. The pressure strip frame 32 is used to press the light guide assembly 2, the buffer layer 33, and the back plate 31 into the face frame 1. The light source assembly 5 is disposed on one side of the light guide assembly 2.

[0050] The face frame 1 includes four frame strips 11 connected end to end. Each frame strip 11 has a serrated groove 111 extending along its length and a first groove 112. The serrated groove 111 is used to lock the pressure strip frame 32 and the back plate 31. The first groove 112 is used to embed the first sealing strip 4. The first sealing strip 4 is located outside the light guide assembly 2, the buffer layer 33 and the back plate 31. The pressure strip frame 32 squeezes the first sealing strip 4 to achieve waterproofing and sealing of the panel light.

[0051] Please refer to Figure 4 The sawtooth groove 111 has sawtooth-shaped locking protrusions 1111 on its two opposite inner walls.

[0052] The first grooves 112 on the four frame strips 11 form an annular groove surrounding the inner side of the face frame 1.

[0053] Please refer to Figure 3 The first sealing strip 4 has a first strip-shaped protrusion 41 extending along the length direction of the first sealing strip 4 on one end face near the pressure strip frame 32.

[0054] Please refer to Figure 3 There are two first strip-shaped protrusions 41, which are located at opposite ends of one end face of the first sealing strip 4 and are spaced apart.

[0055] Please refer to Figure 3 It also includes a second sealing strip 6, and the frame strip 11 is also provided with a second groove 113 extending along the length direction. The second groove 113 is used to embed the second sealing strip 6. The light guide assembly 2 and the second sealing strip 6 are pressed together to achieve waterproofing and sealing of the panel light.

[0056] Please refer to Figure 4 The first groove 112 is located between the serrated groove 111 and the second groove 113, and the position of the first groove 112 is higher than the position of the second groove 113.

[0057] Please refer to Figure 3 The second sealing strip 6 has a second strip-shaped protrusion 61 extending along the length direction of the second sealing strip 6 on one end face near the back plate 31.

[0058] Please refer to Figure 3 There are two second strip-shaped protrusions 61, which are located at opposite ends of one end face of the second sealing strip 6 and are spaced apart.

[0059] The depth of the serrated groove 111 is greater than the depth of the first groove 112.

[0060] Please refer to Figure 3 The light guide assembly 2 includes a light guide plate 21, a diffuser plate 22, and a reflective layer 23 stacked sequentially along the light emission direction of the light source assembly 5. The diffuser plate 22 can be a conventional frosted panel or a light guide plate with a microcrystalline structure on its surface, depending on the actual application. One side of the light guide plate 21 has a scattering protrusion, which scatters light from one beam into multiple beams at different angles to achieve light diffusion. However, the emitted light will also form regular moiré patterns due to the regular arrangement of the scattering dots. To improve the light emission uniformity of the light guide plate 21, the emitted light is scattered again in conjunction with the diffuser plate 22 to eliminate the moiré patterns. The scattering dots can be printed onto the light guide plate using existing mature technologies such as laser engraving, V-shaped cross grid engraving, and UV screen printing.

[0061] The reflective layer 23 is located behind the backlight surface of the light guide plate 21 to improve the overall light output efficiency of the light source assembly 5. For the light source assembly 5, all light rays must eventually be emitted from the light-emitting surface of the light guide plate 21. Therefore, in order to reduce energy loss when light rays travel back and forth in the light guide plate 21 and improve the utilization rate of light energy, a reflective paper is designed at the bottom. Through the reflection effect of the reflective layer 23, the light rays entering the bottom of the light guide plate 21 are redirected, and finally these light rays are output from the light-emitting surface of the light guide plate 21, thereby reducing light energy loss and improving light energy utilization. The reflective layer 23 can be a silver reflective sheet or a white reflective sheet. The material of the white reflective sheet is usually polyester and polypropylene, while the silver reflective sheet usually has a layer of metal mixture plated on its surface, so its reflectivity is very high, even reaching 100% reflectivity. Therefore, in this embodiment, the reflective layer 23 is preferably a silver reflective sheet.

[0062] A buffer layer is sandwiched between the back plate 31 and the reflective layer 23 to provide buffer protection. Preferably, the buffer layer is a sponge pad, which provides buffer protection and enhances the reflective effect of the reflective layer 23 through structural limiting.

[0063] The sealing of the face frame 1, back plate 31, and pressure strip frame 32, as well as the sealing of the face frame 1 and light guide assembly 2, are achieved by pressing the first sealing strip 4 and the second sealing strip 6 against the plane of the face frame 1 through the pressure strip frame 32, back plate 31, and diffuser plate 22. The sealing is achieved by filling the tiny gaps between the sealing interfaces according to the elastic deformation of the sealing strips, blocking the leakage channels. The sealing material is mostly silicone rubber (in this embodiment, both the first sealing strip 4 and the second sealing strip 6 are made of silicone rubber). Silicone rubber is a high-molecular elastic material with high temperature resistance (250℃~300℃) and low temperature resistance (-40℃), UV resistance, anti-aging properties, excellent resilience, and small permanent deformation, providing reliable protection for the product against harsh environments.

[0064] The first sealing strip 4 and the second sealing strip 6 can also be made of foamed silicone as the sealing material. Because it has excellent heat insulation, waterproof and shockproof properties, the foaming principle is mainly achieved through chemical reaction. The base liquid and foaming agent are mixed to form bubbles, which causes the silicone to expand and form foamed silicone. Foamed silicone can maintain its soft and elastic properties for a long time, is environmentally friendly and non-toxic, has excellent chemical stability, is resistant to weathering and aging, is non-corrosive, has low linear shrinkage, and is easy to operate.

[0065] The light source assembly 5 includes a light source board and multiple LED light sources arranged in an array on the light source board. The light source board is long and strip-shaped, and its installation direction is parallel to the frame strip 11. During installation, thermally conductive double-sided adhesive is first applied to the back of the light source board, and then it is applied to the frame strip 11.

[0066] The panel light design in this scheme also includes a power supply 7 and a mounting bracket 8;

[0067] The power supply 7 is externally mounted on the back of the lamp body and is equipped with an aviation plug 71. This method allows for quick maintenance and replacement of the power supply 7, and the power supply 7 can be easily disassembled without tools in the future.

[0068] The mounting bracket 8 is installed on the pressure strip frame 32.

[0069] In summary, this utility model provides a waterproof side-emitting panel light that organically combines a face frame, a light guide assembly, a backlight assembly, a first sealing strip, and a light source assembly to construct a complete and efficient panel light structure system. The pressure strip frame firmly presses the light guide assembly, buffer layer, and back plate into the face frame, forming a stable internal structure. The buffer layer effectively buffers external pressure, protecting internal components from damage. The light source assembly is located on one side of the light guide assembly, achieving a side-emitting effect. This allows light to be evenly diffused through the light guide assembly, resulting in softer and more uniform light compared to traditional direct-emitting light, reducing glare and improving lighting quality. Simultaneously, the serrated grooves on the frame facilitate quick installation and removal of the pressure strip frame and back plate, improving installation and maintenance efficiency. The first sealing strip embedded in the first groove, under the pressure of the pressure strip frame, tightly fits the gaps between components, forming an effective waterproof barrier to prevent moisture intrusion and ensure stable operation of the panel light even in humid environments.
