Description

Technical Field

[0001] This utility model relates to the field of diffusion plate technology, and in particular to a diffusion plate with gray silkscreen dots. Background Technology

[0002] A diffuser plate, also known as a light diffuser or light-diffusing plate, is a crucial component in LED lighting and flat panel display fields. It features high light diffusion, high light transmittance, and the ability to effectively block light sources. The diffuser plate acts as a light-shielding element, blocking the passage of light. Generally, the better the light diffusion of the diffuser plate, the lower its light transmittance.

[0003] However, traditional LED lights generate heat during operation. If the diffuser plate is not heat-resistant enough, it may lead to poor heat dissipation of the light fixture, affecting the lifespan and performance of the LED. Furthermore, in high-temperature environments, a deformed or melted diffuser plate can damage the optical performance of the light fixture, resulting in uneven light distribution or glare. Utility Model Content

[0004] This utility model discloses a diffuser plate with gray silkscreen dots, which aims to solve the technical problems that traditional LED lamps generate heat during operation. If the heat resistance of the diffuser plate is insufficient, it may lead to poor heat dissipation of the lamp, affecting the lifespan and performance of the LED. Furthermore, in high-temperature environments, a deformed or melted diffuser plate may damage the optical performance of the lamp, resulting in uneven light distribution or glare.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A diffuser plate with gray screen-printed dots includes two first substrates and two second substrates, which are fixedly connected. The plate further includes: a first mounting groove and a second mounting groove respectively formed on the inner walls of opposite sides of the two first substrates and the two second substrates; a base plate between the two second substrates; a transparent plate on the top outer wall of the base plate; a flame-retardant layer on the top outer wall of the transparent plate; a top plate on the top outer wall of the flame-retardant layer; a light-diffusing film covering the bottom outer wall of the top plate; the top plate being located between the two first substrates; and a plurality of equidistantly distributed gray screen-printed dots on the top outer wall of the top plate.

[0007] By adopting the above technical solution, the heat dissipation performance of the entire diffuser plate can be improved, its service life can be extended, and the light distribution can be more uniform. Specifically, during use, the heat conduction paths between the flame-retardant layer, the transparent plate, and the base plate work together to transfer heat and assist in heat dissipation, avoiding heat accumulation and thus preventing the diffuser plate from burning due to high temperature and causing safety hazards. Specifically, when the diffuser plate is affected by high temperature, the heat generated inside it will be conducted and dissipated through multiple pathways. The flame-retardant layer, as a key heat protection layer, can effectively isolate external heat sources. At the same time, its internal heat conduction mechanism will quickly transfer heat to the transparent plate. The transparent plate has good light transmittance and a certain degree of thermal conductivity, which can further transfer the received heat to the base plate. The base plate, as the supporting structure of the diffuser plate, has a large heat capacity and thermal conductivity, which helps to disperse and transfer heat to the surrounding environment, thereby achieving an effective heat dissipation effect.

[0008] In a preferred embodiment, the top outer wall of the first substrate and the bottom outer wall of the second substrate are provided with a plurality of equally spaced heat dissipation grooves, the inner wall of the heat dissipation grooves is fitted with a dustproof mesh, and the heat dissipation grooves are respectively connected to the first mounting groove and the second mounting groove.

[0009] In this design, the heat sink is designed to increase the heat dissipation area and improve the heat dissipation efficiency. When the top and bottom plates on the first and second substrates heat up, the heat will be dissipated into the air through the heat sink. The dustproof net is installed on the inner wall of the heat sink. Its main function is to prevent dust and debris from entering the heat sink and affecting the heat dissipation effect. At the same time, the dustproof net can also protect the components inside the heat sink from damage.

[0010] In a preferred embodiment, two first heat-conducting plates and two second heat-conducting plates are respectively provided on one side inner wall of the first mounting groove and the second mounting groove. The first heat-conducting plate abuts against one side outer wall of the top plate, and the second heat-conducting plate abuts against one side outer wall of the bottom plate.

[0011] In this design, when the temperature on the top or bottom plate rises, the heat is quickly conducted to the first and second heat-conducting plates in contact with it. The first and second heat-conducting plates can be made of aluminum, thereby greatly improving the heat dissipation efficiency.

[0012] As described above, a diffuser plate with gray silkscreen dots includes two first substrates and two second substrates, which are fixedly connected. It further includes: a first mounting groove and a second mounting groove respectively formed on the inner walls of opposite sides of the two first substrates and the two second substrates; a bottom plate between the two second substrates; a transparent plate on the top outer wall of the bottom plate; a flame-retardant layer on the top outer wall of the transparent plate; a top plate on the top outer wall of the flame-retardant layer; and a light-diffusing film covering the bottom outer wall of the top plate. The top plate is located between the two first substrates, and its top outer wall is provided with a plurality of equidistantly distributed gray silkscreen dots. The diffuser plate with gray silkscreen dots provided by this invention has the technical effects of improving the heat dissipation performance of the entire diffuser plate, extending its service life, and making the light distribution more uniform.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0018] The diffuser plate with gray silkscreen dots disclosed in this utility model is mainly used in traditional LED lamps that generate heat during operation. If the heat resistance of the diffuser plate is insufficient, it may lead to poor heat dissipation of the lamp, affecting the lifespan and performance of the LED. Furthermore, in high-temperature environments, a deformed or melted diffuser plate may damage the optical performance of the lamp, resulting in uneven light distribution or glare.

[0019] Reference Figure 1 , Figure 2 and Figure 3 A diffusion plate with gray screen-printed dots includes two first substrates 1 and two second substrates 2, which are fixedly connected. It also includes: a first mounting groove and a second mounting groove respectively formed on the inner walls of opposite sides of the two first substrates 1 and the two second substrates 2; a base plate 3 between the two second substrates 2; a transparent plate 4 on the top outer wall of the base plate 3; a flame-retardant layer 5 on the top outer wall of the transparent plate 4; a top plate 7 on the top outer wall of the flame-retardant layer 5; a light-diffusing film 6 covering the bottom outer wall of the top plate 7; the top plate 7 is located between the two first substrates 1; and a plurality of equidistantly distributed gray screen-printed dots are arranged on the top outer wall of the top plate 7.

[0020] It should be noted that the design of gray screen printing dots can precisely control the distribution of ink, thereby affecting the refraction and reflection of light to achieve the ideal visual effect. It also helps light to diffuse more evenly at different angles, reducing glare and improving visual comfort. It is suitable for direct-lit or side-lit LED lighting fixtures, such as downlights and panel lights. It can effectively transform point or line light sources into soft and uniform surface light sources. It can also achieve specific optical effects through design, such as anti-glare and improved fog level. It is suitable for a variety of lighting fixtures to meet different lighting needs.

[0021] Among them, the light diffusion film 6 can be made of polycarbonate (PC) film, which has high transparency, high strength and good heat resistance. PC can also be used as the substrate of the light diffusion film 6, and the light diffusion effect can be achieved by coating with a functional coating.

[0022] In high-temperature environments, the gray screen-printed dots on the surface of the diffuser plate may change color, turning from the original gray to yellow, brown, or other colors. This discoloration can reduce the appearance quality of the product and may also cause changes in the optical performance of the diffuser plate. For example, the light transmittance may decrease and the haze may increase, thus affecting the uniform distribution and diffusion effect of light. It may also shorten the service life of the diffuser plate, requiring more frequent replacement and maintenance. Therefore, when using gray screen-printed dots, high-temperature resistant inks or coatings can be selected to ensure that they do not easily change color in high-temperature environments.

[0023] The first substrate 1 and the second substrate 2 are both "L" shaped structures. The "L" shaped structure has two mutually perpendicular planes. This shape provides a larger installation and fixing area for the transparent plate 4 and the flame-retardant layer 5 inside the diffuser plate, thereby enhancing the stability and reliability of the structure.

[0024] In the specific implementation process, several heat dissipation grooves 9 are provided on the top outer wall of the first substrate 1 and the bottom outer wall of the second substrate 2 at equal intervals. A dustproof net 8 is installed on the inner wall of the heat dissipation groove 9. The heat dissipation groove 9 is connected to the first mounting groove and the second mounting groove respectively. The design of the heat dissipation groove 9 is mainly to increase the heat dissipation area and improve the heat dissipation efficiency. When the top plate 7 and the bottom plate 3 heat up, the heat will be dissipated into the air through the heat dissipation groove 9. The dustproof net 8 is installed on the inner wall of the heat dissipation groove 9. Its main function is to prevent dust and debris from entering the interior of the heat dissipation groove 9 and affecting the heat dissipation effect. At the same time, the dustproof net 8 can also protect the components inside the heat dissipation groove 9 from damage.

[0025] Specifically, during use, the heat conduction paths between the flame-retardant layer 5, the transparent plate 4, and the base plate 3 work together to transfer heat and assist in heat dissipation, preventing heat accumulation and thus preventing the diffuser plate from burning due to high temperature and causing safety hazards. Specifically, when the diffuser plate is affected by high temperature, the heat generated inside it will be conducted and dissipated through multiple pathways. As a key heat protection layer, the flame-retardant layer 5 can effectively isolate external heat sources. At the same time, its internal heat conduction mechanism will quickly transfer heat to the transparent plate 4. The transparent plate 4 has good light transmittance and a certain degree of thermal conductivity, which can further transfer the received heat to the base plate 3. As the supporting structure of the diffuser plate, the base plate 3 has a large heat capacity and thermal conductivity, which helps to disperse and transfer heat to the surrounding environment, thereby achieving an effective heat dissipation effect.

[0026] Reference Figure 2 and Figure 3 In a preferred embodiment, two first heat-conducting plates 10 and two second heat-conducting plates 11 are respectively provided on one side inner wall of the first mounting groove and the second mounting groove. The first heat-conducting plate 10 abuts against one side outer wall of the top plate 7, and the second heat-conducting plate 11 abuts against one side outer wall of the bottom plate 3.

[0027] A mounting cavity 12 is formed between the first substrate 1 and the second substrate 2, and the transparent plate 4 and the flame-retardant layer 5 are both located inside the mounting cavity 12.

[0028] Specifically, when the temperature on the top plate 7 or the bottom plate 3 rises, the heat will be quickly conducted to the first heat-conducting plate 10 and the second heat-conducting plate 11 that are in contact with it. The first heat-conducting plate 10 and the second heat-conducting plate 11 can be made of aluminum, thereby greatly improving the heat dissipation efficiency.

[0029] Reference Figure 2In a preferred embodiment, the flame retardant layer 5 is made of fiberglass cloth, which has a variety of excellent properties such as high strength, high modulus, corrosion resistance, high temperature resistance and flame retardancy. It can maintain stable performance in high temperature environment and is not easily deformed or melted.

[0030] Reference Figure 2 In a preferred embodiment, the transparent plate 4 is made of acrylic sheet, and light will be softly scattered after passing through the acrylic sheet, making the light more uniform and softer.

[0031] Working principle: During use, the heat conduction paths between the flame-retardant layer 5, the transparent plate 4, and the base plate 3 work together to transfer heat and assist in heat dissipation, preventing heat accumulation and thus preventing the diffuser plate from burning due to high temperature and causing safety hazards. Specifically, when the diffuser plate is affected by high temperature, the heat generated inside it will be conducted and dissipated through multiple pathways.
