Description

Technical Field

[0001] The present application relates to the field of lampshade technology, and in particular to an LED lampshade packaging structure. Background Art

[0002] As an energy-efficient light source technology, LED has been widely used in the field of modern lighting. With its long life, high light efficiency and environmental protection characteristics, LED lamps have gradually replaced traditional light sources and become the mainstream of the lighting market. However, in practical applications, the packaging structure design of LED lamps still faces many technical challenges, especially the balance between waterproof sealing performance and optical performance.

[0003] The current LED lampshade packaging structure on the market often has deficiencies in waterproof performance and is prone to water seepage and leakage. This phenomenon not only causes the internal components of the lamp to be damaged by moisture, shortening the life of the lamp, but may also cause electrical failures and pose safety hazards. In addition, while ensuring the sealing, the existing packaging design often affects the light transmittance of the lampshade, resulting in uneven light distribution and affecting the lighting effect. Although traditional packaging materials such as plastic and glass provide waterproof protection to a certain extent, their long-term stability and optical performance still need to be improved.

[0004] Therefore, the LED lampshade packaging structure in the prior art has significant defects in waterproof sealing and optical performance, and an improved packaging structure is needed to solve the problem of water seepage and leakage while ensuring good light transmission performance. Utility Model Content

[0005] In order to alleviate the problem that waterproof performance and optical performance of related LED lampshades cannot be taken into account at the same time, the present application provides an LED lampshade packaging structure.

[0006] The present application provides an LED lampshade packaging structure that adopts the following technical solution:

[0007] An LED lampshade packaging structure, comprising:

[0008] A shell plate, one side of which is provided with a receiving groove for light intake;

[0009] An infrared lamp cover, the infrared lamp cover is connected to a side of the shell plate away from the receiving groove, and an annular groove is provided at the connection;

[0010] A waterproof sealing ring is embedded in the groove, the middle part of the waterproof sealing ring protrudes outward to form a convex edge, and the convex edge of the waterproof sealing ring can be interference-fitted with the assembled shell plate to be configured to block water vapor from entering the receiving groove from the side wall of the infrared lamp cover.

[0011] By adopting the above technical solution, an annular groove is designed at the connection between the infrared lampshade and the shell plate, and a transparent waterproof sealing ring is filled. The transparent waterproof sealing ring in the annular groove not only plays a fixing role, but also the convex edge in the middle squeezes the two sides of the waterproof sealing ring, and has an interference fit with the edge of the groove. The interference fit generates a pre-tightening force through the elastic deformation of the waterproof sealing ring, so that it fits tightly with the edge of the groove to form a highly reliable seal. This tight fit can effectively prevent external moisture, dust and other pollutants from entering the interior of the lampshade, ensuring that the LED lamp can maintain excellent protection performance in various environments. At the same time, compared with the problem that traditional sealing materials may scatter and absorb light, resulting in reduced light efficiency, the transparent waterproof sealing ring can ensure that the light is not significantly obstructed when passing through the sealed area, maintain high light transmittance, and thus improve the overall optical performance of the lamp. In addition, the shell plate is provided with a receiving groove to optimize the incident angle of the light, so that the light can be more evenly distributed inside the lampshade, reducing light loss and improving light efficiency.

[0012] Optionally, the waterproof sealing ring includes a sealing outer layer, a heat-conducting middle layer and a heat-conducting inner layer, the thermal conductivity of the heat-conducting middle layer is smaller than the thermal conductivity of the heat-conducting inner layer, and the sealing outer layer, the heat-conducting middle layer and the heat-conducting inner layer are integrally formed.

[0013] By adopting the above technical solutions, the sealed outer layer provides excellent waterproof and dustproof capabilities, ensuring that moisture and dust in the external environment cannot penetrate into the interior of the lamp, thereby protecting the normal operation of the internal components. Secondly, the layered design of the thermal conductive middle layer and the thermal conductive inner layer effectively improves the thermal management capabilities of the lamp. The high thermal conductivity of the thermal conductive inner layer enables it to quickly conduct the heat generated by the LED light source, ensuring that the heat can be dissipated from the inside in time to prevent overheating. The thermal conductive middle layer, due to its low thermal conductivity, can slow down the heat conduction speed to a certain extent and play a buffering role, thereby avoiding excessively concentrated heat transfer to the sealed outer layer and maintaining the stability and integrity of the sealed outer layer. Through one-piece molding, it can be ensured that there are no gaps between the layers, thereby avoiding sealing failure or decreased thermal conductivity due to loose bonding between layers.

[0014] Optionally, the protrusion includes a plurality of sub-sealing ribs, and each sealing rib extends in a spiral line along the height direction of the waterproof sealing ring.

[0015] By adopting the above technical solution, the provision of multiple sub-sealing ribs increases the contact area between the sealing ring and the shell plate, and the sealing ribs can be in close contact with the shell plate over a larger range through the extension of the spiral line. The characteristics of the spiral line are utilized to enhance the friction between the sealing ring and the shell plate during installation, thereby forming a tighter and more reliable seal and further preventing the entry of moisture and dust. Secondly, the sub-sealing ribs extended by the spiral line can effectively disperse external pressure. When the sealing ring is squeezed by external force, the spiral line structure can evenly disperse the pressure on the entire sealing ring to avoid local stress concentration. Not only does it improve the durability of the sealing ring, but it can also prevent deformation or damage caused by excessive local pressure during use, thereby extending the service life of the sealing ring.

[0016] Optionally, a reflective sheet is provided on one side of the shell plate close to the waterproof sealing ring, and the reflective sheet is inclined toward the side of the infrared lamp cover close to the waterproof sealing ring.

[0017] By adopting the above technical solution, the inclined reflector can effectively redirect the scattered or reflected light to the waterproof sealing ring area that is less exposed to direct light, so that the light intensity in these areas is enhanced. The original waterproof sealing ring area is light compensated, thereby reducing the difference in light intensity between the waterproof sealing ring area and other areas, making the light evenly distributed and improving the overall lighting effect.

[0018] Optionally, an adjustment structure is provided on a side of the reflective sheet close to the inner wall of the shell plate, and the adjustment structure is used to adjust the inclination angle of the reflective sheet.

[0019] By adopting the above technical solution, the adjustment structure allows the inclination angle of the reflector to be precisely controlled. By changing the angle of the reflector, the reflection path and emission direction of the light can be optimized, so that the lamp can be adjusted according to the situation, thereby achieving different lighting effects and adapting to a variety of usage scenarios. Secondly, the adjustment structure helps to maximize the utilization of light. By adjusting the angle of the reflector, it can ensure that more light is effectively reflected and directed to the required area, reducing light waste and improving the overall light efficiency of the lamp.

[0020] Optionally, the inner surface of the infrared lamp cover is provided with microstructures, and the microstructures are evenly distributed to enhance the scattering and reflection of light.

[0021] By adopting the above technical solution, the evenly distributed microstructure can effectively increase the scattering and reflection of light. The microstructure can break the single propagation path of light, and through multiple scattering and reflection, the light is more evenly distributed inside the lampshade, which can significantly reduce the generation of light spots and shadows, ensure that the light output by the lamp is more uniform and soft, and improve the overall lighting effect and visual comfort. Secondly, through the effective scattering and reflection of light, part of the absorbed or reflected light can be redirected to the light-emitting surface of the lampshade, which can improve the brightness and light efficiency of the lamp without increasing power consumption.

[0022] Optionally, the microstructure is a microlens array, a microprism array or a dot structure.

[0023] By adopting the above technical solution, the microlens array can effectively focus and redistribute the incident light through the arrangement of multiple tiny lenses. Each microlens can converge the light to a specific area, thereby improving the concentration and brightness of the light, achieving efficient light utilization, reducing light loss, and improving the overall light efficiency of the lamp. Secondly, the microprism array can refract and reflect the incident light multiple times through the arrangement of tiny prisms. Each microprism can change the propagation path of the light so that the light is evenly distributed inside the lampshade, thereby reducing the generation of light spots and shadows, ensuring the uniformity of the light, and improving the lighting quality and visual comfort. In addition, the dot structure can scatter and diffuse the light through regular or irregular dot arrangements. The dot structure can break the single propagation path of the light and scatter the light multiple times inside the lampshade, thereby forming a soft and uniform light distribution.

[0024] Optionally, the connection between the shell plate and the infrared lamp cover is a detachable connection.

[0025] By adopting the above technical solution, the detachable connection design makes the installation and removal of the lamp more convenient. Users can easily remove the infrared lamp cover from the shell plate to inspect, clean and replace the internal components, which simplifies the maintenance process, reduces maintenance time and cost, and improves the maintainability of the lamp. Secondly, the detachable connection design enhances the diversity and adaptability of the lamp. By replacing lamp covers with different functions, the same shell plate can be adapted to a variety of lighting needs.

[0026] Optionally, the connection between the shell plate and the infrared lamp cover further includes a buckle structure, and the buckle structure includes a buckle and a slot respectively arranged on the shell plate and the infrared lamp cover.

[0027] By adopting the above technical solution, the buckle structure makes the connection between the shell plate and the infrared lampshade more stable through the cooperation of the buckle and the slot. The mechanical locking effect of the buckle and the slot can ensure that the lampshade will not loosen or fall off when subjected to external force or vibration, thereby improving the overall stability and reliability of the lamp. Secondly, the buckle structure makes the installation and removal of the lampshade more convenient. The user only needs a simple push and pull action to complete the fixing and removal of the lampshade without the use of additional tools. The complexity of operation is reduced and the user experience is improved.

[0028] Optionally, a mounting hole is provided on one side of the shell plate close to the accommodating groove, and the mounting hole is used to fix the LED light source.

[0029] By adopting the above technical solution, the position of the mounting hole is close to the receiving groove, which can ensure the stable installation of the LED light source. By fixing the LED light source through the mounting hole, it can prevent it from being displaced or loosened during use, thereby ensuring the stability and reliability of the lamp. Stable installation can ensure the accurate position of the light source and help achieve the expected lighting effect. In addition, by fixing the LED light source in a position close to the shell plate, the heat dissipation function of the shell plate can be effectively utilized to dissipate heat in time, avoid overheating of the light source, and extend its service life.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0039] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0040] The embodiment of the present application discloses an LED lampshade packaging structure.

[0041] Reference Figure 1 and Figure 2 , an LED lampshade packaging structure includes a shell plate 1, an infrared lampshade 2 and a waterproof sealing ring 3. The shell plate 1 is used to fix and install the LED light source 8, and a receiving groove 11 is designed on one side of the shell plate 1 to ensure that the light enters the lampshade smoothly. The surface of the receiving groove 11 is refined to reduce the scattering and absorption of light. In order to ensure the stable installation of the LED light source 8, a plurality of mounting holes 7 are also provided on the side of the shell plate 1 close to the receiving groove 11, and the mounting holes 7 are distributed around the receiving groove 11. Multi-point support and fixation are provided to prevent the LED light source 8 from being displaced or loosened due to vibration or other external forces during use. Through the mounting holes 7, the LED light source 8 can be firmly fixed on the shell plate 1, which not only improves the stability and reliability of the lamp, but also ensures the accurate position of the light source, and is convenient for the replacement and maintenance of the LED light source 8. The installation and disassembly can be completed with simple operations, which greatly improves the convenience of use. In addition, attached to the shell plate 1, heat can be dissipated through the shell plate 1, and the heat can be dissipated in time to avoid overheating of the light source.

[0042] The other side of the shell plate 1 is connected to the infrared lampshade 2 through a buckle 61 structure, which includes a buckle 61 provided on the shell plate 1 and a corresponding slot 62 provided on the infrared lampshade 2. When the lampshade is aligned with the shell plate 1, the buckle 61 will fit tightly with the slot 62 with a simple press, forming a mechanical lock, so that the connection between the lampshade and the shell plate 1 is stable, and the lampshade can be prevented from loosening or falling off when subjected to external force or vibration. At the same time, the buckle 61 connection makes the installation and removal of the lampshade easier and faster, without the need for additional tools, greatly improving the installation efficiency and maintenance convenience.

[0043] The connection is also designed with an annular groove and filled with a transparent waterproof sealing ring 3. The annular groove provides sufficient space for sealing, and the transparent waterproof sealing ring 3 is filled in the groove and fits tightly with the edge of the groove through its excellent elasticity and compressibility, thereby forming a highly reliable sealing structure.

[0044] The transparent waterproof sealing ring 3 also has excellent optical properties. Traditional sealing materials such as rubber or some plastics are prone to scattering and absorption when light passes through, resulting in reduced light efficiency. However, the transparent waterproof sealing ring 3 can ensure that the light is not significantly obstructed when passing through the sealed area, maintaining high light transmittance. When the light passes through the waterproof sealing ring 3, its brightness and directionality will not be significantly reduced or changed due to the absorption and scattering of the material. While maintaining good sealing, the lamp ensures efficient transmission and uniform distribution of light, thereby improving the overall lighting effect.

[0045] The middle part of the waterproof sealing ring 3 is designed to bulge outward to form a convex edge. During the assembly process, the convex edge will squeeze the two sides of the waterproof sealing ring 3 so that it forms an interference fit with the edge of the annular groove. The interference fit generates a preload through the elastic deformation of the waterproof sealing ring 3, so that the waterproof sealing ring 3 fits tightly with the edge of the groove, thereby achieving a highly reliable seal. At the same time, when the convex part contacts the edge of the groove, the waterproof sealing ring 3 is elastically deformed, so that the waterproof sealing ring 3 is firmly fixed in the groove to prevent displacement or loosening under the action of external force. This interference fit has a self-locking characteristic, ensuring that the waterproof sealing ring 3 can remain stable even in a vibration or impact environment, avoiding sealing failure due to loosening.

[0046] The convex edge includes a plurality of sub-sealing ribs that extend in a spiral along the height direction of the waterproof sealing ring. Although not shown in the figure, these sub-sealing ribs increase the contact area between the sealing ring and the shell plate. The spiral shape allows it to be in close contact with the shell plate over a larger range, enhancing the friction during installation, thereby forming a tighter and more reliable seal to prevent moisture and dust from entering. In addition, the spirally extending sub-sealing ribs can effectively disperse the external pressure, evenly distribute the pressure to the entire sealing ring, and avoid local stress concentration. This not only improves the durability of the sealing ring, prevents deformation or damage caused by excessive local pressure, but also extends the service life of the sealing ring.

[0047] The waterproof sealing ring 3 is composed of a sealing outer layer, a heat-conducting middle layer and a heat-conducting inner layer, and is integrally formed. The thermal conductivity of the heat-conducting middle layer is lower than that of the heat-conducting inner layer. The sealed outer layer provides excellent waterproof and dustproof capabilities, prevents external moisture and dust from entering the interior of the lamp, and protects the normal operation of internal components. Due to its high thermal conductivity, the heat-conducting inner layer can quickly conduct the heat generated by the LED light source 8, dissipate heat in time, and prevent overheating. The heat-conducting middle layer slows down heat conduction through its lower thermal conductivity, acts as a buffer, avoids heat concentration in the sealed outer layer, and ensures its stability and integrity. The one-piece molding design ensures that there is no gap between the layers, preventing sealing failure and degradation of thermal conductivity due to loose bonding.

[0048] In addition, reference Figure 3 and Figure 4A reflective sheet 4 is provided on the side of the receiving groove 11 of the shell plate 1 close to the waterproof sealing ring 3. The reflective sheet 4 is inclined toward the side of the infrared lamp cover 2 close to the waterproof sealing ring 3, and can capture and redirect light to a large extent. By changing the propagation path of the light, the light is directed to the area of ​​the waterproof sealing ring 3 that is less exposed to direct light, so that the light can be accurately guided to the area that needs supplementary light, effectively making up for the lack of light in these areas, and making the light distribution inside the lamp cover more uniform.

[0049] At the same time, an adjustment structure 5 is designed at the connection between the reflector sheet 4 and the shell plate 1. By rotating the adjustment shaft, the angle of the reflector sheet 4 can be flexibly changed to optimize the reflection path and emission direction of the light, so that the light can be effectively reflected and directed to a specific area. This not only improves the adaptability of the lamp, but also enables the lamp to perform at its best in different occasions.

[0050] Furthermore, microstructures 21 are provided on the inner surface of the infrared lampshade 2. These microstructures 21 are evenly distributed to enhance the scattering and reflection of light. The working principle of the microstructure 21 is that it can change the propagation direction of light, so that it undergoes multiple refractions and reflections inside the lampshade, thereby forming a uniform light distribution. This multiple scattering and reflection mechanism can effectively eliminate bright spots caused by concentrated light, fill in shadow areas, and make the light intensity of the entire lighting area more consistent. Secondly, through effective scattering and reflection of light, the microstructure 21 can also redirect part of the absorbed or reflected light to the light-emitting surface of the lampshade. Not only does it improve the utilization efficiency of light, but it can also significantly improve the brightness and light efficiency of the lamp without increasing power consumption.

[0051] The microstructure 21 can be a microlens array, a microprism array or a dot structure. In this embodiment, a dot structure is used. The dot structure arranges dots of different sizes and spacings on the inner surface of the lampshade, so that the incident light is scattered and diffused multiple times when passing through the dots, breaking the single propagation path of the light. The effect of multiple scattering can make the light more evenly distributed inside the lampshade, forming soft and uniform light, significantly reducing the generation of light spots and shadows, thereby improving the overall lighting effect and visual comfort.

[0052] In another parallel embodiment, a microlens array or a microprism array may be used. A microlens array is composed of a plurality of tiny lenses arranged in an array, each of which can effectively focus and redistribute the incident light. The curved surface of the lens can focus the light to a specific area, improve the concentration and brightness of the light, and thus achieve efficient light utilization. The microlens array is particularly suitable for application scenarios that require concentrated light, such as display lighting or accent lighting, which can highlight the brightness of a specific area.

[0053] The micro-prism array refracts and reflects the incident light multiple times through the arrangement of tiny prisms. The refractive and reflective surfaces of each micro-prism can change the propagation path of the light, so that the light is evenly distributed in the entire lighting area after multiple refractions and reflections inside the lampshade. The design of the micro-prism array can effectively reduce the generation of light spots and shadows, ensuring the uniformity of light. It is suitable for scenes that require large-area uniform lighting, such as offices, classrooms, and public places.

[0054] The implementation principle of an LED lampshade packaging structure in the embodiment of the present application is:

[0055] The embodiment of the present application discloses an LED lampshade packaging structure, which aims to improve the overall performance and adaptability of the lamp by optimizing the optical performance and sealing performance. The shell plate 1 is connected to the infrared lampshade 2 by a buckle 61 structure to ensure stability. An annular groove is designed at the connection point and filled with a transparent waterproof sealing ring 3. The waterproof sealing ring 3 forms an interference fit with the edge of the groove through its elasticity and compressibility, generates a pre-tightening force, achieves a highly reliable seal, prevents moisture and dust from entering, and maintains a high light transmittance, thereby improving the optical performance of the lamp.

[0056] A reflector 4 is provided on one side of the receiving groove 11 of the shell plate 1 near the waterproof sealing ring 3. The inclined design redirects the light to the waterproof sealing ring 3 area, reduces the light intensity difference through light compensation, and makes the light evenly distributed. An adjustment structure 5 is provided at the connection between the reflector 4 and the shell plate 1, which allows the inclination angle of the reflector 4 to be precisely controlled, optimizes the light reflection path, and maximizes the light utilization. In addition, a microstructure 21 is provided on the inner surface of the infrared lampshade 2, which is evenly distributed to enhance the scattering and reflection of light. The microstructure 21 can be a dot structure, a microlens array, or a microprism array, which further optimizes the light distribution and improves the lighting quality and visual comfort.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
