Abstract
Description
Technical Field
[0001] This invention relates to the field of lamp panel packaging, and more particularly to a lamp panel assembly and its assembly method. Background Technology
[0002] In display and lighting applications such as display panels and flat panel lamps, rigid components such as support members are typically used to fix the lamp panel in place. This fixation ensures the flatness of the lamp panel and enhances its strength after assembly. In existing technologies, the common practice is to weld several threaded post pins with internal threads to the lamp panel's mounting surface. Then, threaded components with external threads are used to fix the support member to the lamp panel, achieving a fixed connection. The biggest drawback of this method is that welding easily leads to localized heat deformation of the lamp panel, and once the solder is fixed, it is difficult to correct any misalignment. This significantly increases the precision requirements for lamp panel processing, resulting in high processing costs and low production efficiency.
[0003] Therefore, how to reduce the positioning error rate when connecting the lamp board and the support component in the lamp board assembly, reduce the assembly cost of the lamp board assembly, and improve production efficiency has become an urgent problem to be solved. Summary of the Invention
[0004] In view of the shortcomings of the above-mentioned related technologies, the purpose of this application is to provide a lamp panel assembly and its assembly method, which aims to solve the problems of high processing costs and low production efficiency between the lamp panel and the support components during the assembly of lamp panel assemblies in the prior art.
[0005] To address the aforementioned technical problems, this application provides a lamp panel assembly, including a lamp panel; a support member fixedly connected to the lamp panel; and a connecting assembly for connecting the lamp panel and the support member. The connecting assembly includes a first connector and a second connector. The support member has opposing first and second surfaces. The lamp panel has opposing third and fourth surfaces. The support member has mounting holes penetrating the first and second surfaces. The first connector passes through the mounting holes from the first surface and is detachably fixedly connected to the second connector located on the second surface. The second connector is fixedly connected to the third surface of the lamp panel by adhesive. Neither the support member nor the first connector is in contact with the adhesive.
[0006] This invention uses adhesive to fix the support and the second connector, which is less prone to error than welding. The detachable connection also facilitates the maintenance of the lamp panel assembly. The lamp panel and the support can be disassembled and assembled by removing and installing the fixed connection between the first connector and the second connector.
[0007] Optionally, the first connector includes a threaded component with external threads, and the second connector includes a threaded post with internal threads. The threaded component has a nut portion and a screw portion. The diameter of the nut portion is larger than the diameter of the screw portion.

[0010] Optionally, the bottom surface of the base is larger than the bottom surface of the screw hole portion.
[0011] Optionally, the support member is provided with a first protrusion facing the lamp panel, the first protrusion protruding outward from the edge of the mounting hole and not in contact with the adhesive.
[0012] Optionally, the support member has a second protrusion at its edge and middle, which faces the lamp panel. The second protrusion is the part of the support member closest to the lamp panel. The distance from the second protrusion to the lamp panel is greater than the distance from the second connector to the lamp panel. The second protrusion is strip-shaped or column-shaped.
[0013] Optionally, the lamp panel is provided with a first adhesive reservoir for holding adhesive.
[0014] Optionally, a second adhesive groove is provided at the bottom of the second connector.
[0015] Based on the same inventive concept, this application also provides a method for assembling a lamp panel assembly, the method comprising the following steps:
[0016] S101, a support member, a lamp panel, and a plurality of connecting components are provided. The connecting components include a first connector and a second connector. The support member has a first surface for connecting with the lamp panel and a second surface opposite to the first surface. The lamp panel has a third surface for connecting with the support member and a fourth surface opposite to the third surface. The support member is provided with mounting holes penetrating the first surface and the second surface of the support member.
[0017] S102, the first connector is pre-passed through the mounting hole and detachably and fixedly connected to the second connector, the second connector being installed on the first surface;

The support member, the first connecting member, and the adhesive do not contact each other. This invention uses adhesive to fix the second connecting member instead of welding, which is less prone to errors, and the detachable connection facilitates subsequent maintenance of the lamp panel assembly. The assembly method provided by this invention improves installation accuracy and reduces error rate by pre-fixing the connecting assemblies on the support member and then bonding each connecting assembly to the lamp panel in one go using adhesive. This reduces the production cost of the lamp panel assembly and improves production efficiency. Attached Figure Description

Detailed Implementation
[0033] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0035] This invention provides a method for assembling a lamp panel assembly. The lamp panel assembly produced by this method significantly reduces the error rate while ensuring assembly reliability, and also improves production efficiency. For ease of understanding, the lamp panel assembly method is illustrated below.
[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a lamp panel assembly 1 comprising:
[0037] The support member 20, the lamp panel 10, and the connecting assembly 30 are provided. The connecting assembly 30 includes a first connector 31 and a second connector 32. The support member 20 has a first surface 21 for connecting with the lamp panel 10 and a second surface 22 opposite to the first surface 21. The lamp panel 10 has a third surface 11 for connecting with the support member 20 and a fourth surface 12 opposite to the third surface 11. The support member 20 is provided with mounting holes 22 that penetrate the first surface 21 and the second surface 22 of the support member 20.
[0038] The first connector 31 passes through the mounting hole 22 and is detachably and fixedly connected to the second connector 32 (detachable, meaning it can be disassembled with tools or by hand; fixedly connected, meaning there is no looseness between the first connector 31, the second connector 32, and the mounting hole). The second connector 32 is mounted on the first surface 21. Adhesive 13 is provided on the third surface 11 at the position corresponding to the second connector 32. The adhesive 13 bonds the second connector 32 to the third surface 11 of the lamp panel, and the support member 20 does not contact the adhesive 13. This avoids the adhesive 13 from bonding with the support member 20 during the assembly of the lamp panel assembly 1, which would make disassembly difficult.
[0039] The lamp panel assembly provided in this embodiment of the invention uses adhesive 13 to connect the second connector, which can avoid the local heat deformation of the lamp panel caused by the welding process used in the prior art. Compared with solder, adhesive 13 is easier to repair, and even if the bonding position of a certain second connector is wrong, it is easy to correct.
[0040] The main components of the lamp panel assembly 1 in this application embodiment include a lamp panel 10 and a support member 20 for fixing and supporting the lamp panel 10. Depending on the type of the lamp panel assembly 1, it may include a display type lamp panel or an illumination type lamp panel; specifically, a display type lamp panel may include a direct-lit backlight panel or an LED direct-display lamp panel. For example, the lamp panel assembly of this application can be used as a lamp panel in the display module of Chinese invention patent application number 202210756999.7, filed on June 29, 2022. It can also be used as a light source in other applications such as backlight modules. To facilitate understanding of the uses of the lamp panel assembly, Chinese patent application number 202210756999.7 is incorporated herein by reference in its entirety. The light sources disposed on the lamp panel 1 include multiple arrays disposed on the emitting surface (in this application, the emitting surface is the fourth surface 12 of the lamp panel 10, see reference 12). Figure 6 The light-emitting chips (shown) are typically arranged at equal intervals in a horizontal and vertical manner, meaning that the spacing between any two adjacent light-emitting chips in the horizontal direction is equal, and the spacing between any two adjacent light-emitting chips in the vertical direction is equal. In terms of size classification, the light-emitting chips in this embodiment of the invention can include at least one of Mini LED chips and Micro LED chips; in terms of the distribution of the light-emitting chip electrodes, they can include at least one of flip-chip, upright-mount, and vertical-mount light-emitting chips. Depending on the processing technology, the die bonding of the light-emitting chips on the lamp board 10 can be performed before or after the lamp board 10 is assembled with the support member 20.
[0041] The support member 20 (also known as the base shell) is made of a rigid material with a relatively stable shape, not easily subject to elastic or inelastic deformation. For example, it can be a metal, including alloys, or a rigid plastic. The support member 20 is typically an integrated structure matching the size of the light panel. For instance, it can be an integrated support plate similar in size to the light panel 10, or a shell structure with a contour that matches the display to be assembled with the light panel assembly 1. Furthermore, for considerations such as portability or cost, the support member 20 can also be a frame structure composed of several reinforcing ribs, as long as it meets the specific application requirements of the light panel assembly 1. The fixed connection between the light panel 10 and the support member 20 is achieved through the assembly method of the light panel assembly in this embodiment of the invention.
[0042] The specific structure of the lamp board 10 in this embodiment of the invention may include a circuit board and a plurality of light-emitting chips disposed on the light-emitting surface of the circuit board. The circuit board may be made of a rigid material, such as, but not limited to, phenolic paper laminate, epoxy paper laminate, epoxy glass cloth laminate, BT resin board, or glass board. In some examples, corresponding circuits may be integrated into or on the surface of the circuit board according to application requirements, such as circuits connected to the light-emitting chips and driving circuits. It should be understood that the light-emitting surface of the circuit board in the above examples of this invention is provided with pads for electrical connection to the electrodes of the light-emitting chips, and the number and arrangement of these pads can be flexibly set according to application requirements. For example, multiple pads may be arranged in an array on the circuit board, or pads in adjacent rows may be staggered. In some examples of this invention, the material of the pads may be, but not limited to, copper, silver, gold, etc.
[0043] In this embodiment of the invention, the electrodes of the light-emitting chip can be electrically connected to the corresponding pads via, but not limited to, conductive adhesive or solder. When using solder, the solder can be, but is not limited to, lead-containing solder alloys, such as tin-lead (Sn-Pb) alloys, tin-lead-bismuth (Sn-Pb-Bi) alloys, or tin-lead-silver (Sn-Pb-Ag) alloys; or lead-free solder alloys, such as tin-silver (Sn-Ag) alloys, tin-bismuth (Sn-Bi) alloys, tin-zinc (Sn-Zn) alloys, tin-antimony (Sn-Sb) alloys, tin-silver-copper (Sn-Ag-Cu) alloys, or tin-bismuth-silver (Sn-Bi-Ag) alloys.
[0044] Specifically, the support member 20 is provided with a plurality of mounting holes 22 penetrating two opposite surfaces of the support member 20. The purpose of the mounting holes 22 is to allow the connecting components 30 to be pre-connected to the support member 20 based on the mounting holes 22. In this embodiment, the mounting holes 22 provided on the support member 20 are usually arranged in an array, that is, regularly arranged on the support member 20. Generally speaking, the number of connecting components 30 is the same as the number of mounting holes. If the strength allows, the number of connecting components 30 can also be set to be less than the number of mounting holes 22. That is, not all mounting holes 22 on the support member 20 will be used for fixing the connecting components.
[0045] The fixing between the connecting component 30 and the support member 20 is detachable. To achieve this detachable connection, the connecting component 30 includes two parts: a first connecting member 31 and a second connecting member 32. The first connecting member 31 and the second connecting member 32 can pass through the through hole 22 to connect with the support member 20. This means that the first connecting member 31, the second connecting member 32, and the support member 20 form a detachable fixed connection. Based on this detachable connection, once the connection is disassembled, the support member 20 can be separated from the lamp panel 10 after assembly, and this separation operation will not damage the adhesive structure between the connecting component 30 and the lamp panel 10. In this embodiment of the invention, the first connecting member 31 and the second connecting member 32 achieve a detachable connection based on the mounting hole 22. Specific implementations of this detachable connection include, but are not limited to, snap-fit connections, tenon and mortise connections, threaded connections, etc.
[0046] Specifically, in some alternative embodiments, refer to, for example Figure 3 and Figure 4 As shown, taking a threaded connection as an example, the first connecting member 31 includes a threaded part 31 with external threads, and the second connecting member 32 includes a threaded post 32 with internal threads. The threaded part 31 and the threaded post 32 are detachably connected through the engagement of internal and external threads. The threaded part 31 is located on the upper surface of the support member 20, and its threaded portion with external threads can pass through the mounting hole 22 on the support member 20. The threaded post is located on the lower surface of the support member 20, and the external thread of the threaded part can extend into the internal thread of the threaded post. The detachable fixed connection between the threaded part and the threaded post is achieved through the engagement of internal and external threads. The bottom of the threaded post 32 is bonded to the lamp plate 10 with adhesive 13. After the lamp plate 10 and the support member 20 are assembled, the lamp plate 10 can be separated from the support member 20 by disassembling the threaded engagement between the threaded part 31 and the threaded post 32. Please refer to [reference needed]. Figure 4 This is a diagram showing the disassembly of the assembled lamp panel assembly.
[0047] In some alternative embodiments, please refer to Figure 3To improve the reliability of the bonding between the screw post 32 and the lamp panel 10, the screw post 32 may specifically include an integrally formed screw hole portion 321 and a base 322. The base 322 is closer to the lamp panel 10 than the screw hole portion 321, and the base 322 closes the bottom of the screw post 32 to prevent the adhesive 13 from contacting the threaded part 31. Furthermore, the bottom area of the base 322 is larger than the bottom surface of the screw hole portion 321 to increase the contact area between the base 322 and the adhesive 13, thereby enhancing the bonding force between the screw post 32 and the third surface 11 of the lamp panel 10. In this embodiment, the screw hole portion 321 is cylindrical, and the base 322 is circular, with an outer diameter larger than the outer diameter of the screw hole portion 321. In other embodiments, the base may also be square, elliptical, or other shapes.
[0048] refer to Figure 5aAs shown in this embodiment of the invention, in order to assemble the lamp panel assembly, the assembly 30 can be pre-fixed on the support member 20. To facilitate the fixing of the assembly 30 to the support member 20, at least a portion of the second connector 31 (a threaded post in this embodiment) connected to the first connector 31 (a threaded member in this embodiment) is embedded in the mounting hole 23. That is, the portion of the mounting hole 23 facing the first connector 31 can accommodate a portion of the first connector 31 extending into it, and the portion of the mounting hole 23 facing the second connector 31 can accommodate a portion of the second connector 32. This makes the mounting hole 23 have a limiting effect on the first connector 31 and the second connector 32, facilitating the pre-fixing of the second support member 32 when installing it on the support member 20. First, a limiting position is established to facilitate connection with the first mounting component 31. Specifically, in this embodiment, the first mounting component 31 is a threaded component, having a nut portion 311 and a screw portion 312, with the diameter of the nut portion 311 being larger than that of the screw portion 312. The second mounting component 32 is a threaded post 32, and the mounting hole 23 is a stepped hole. The first diameter 231 of the mounting hole 23 facing the threaded component 31 is larger than the diameter of the screw portion 312 but smaller than the diameter of the nut portion 311. The second diameter 232 of the mounting hole 23 facing the threaded post 32 is larger than the outer diameter of the threaded post 32. During installation, a portion of the threaded post 32 can be inserted into the mounting hole 23 first, and then the threaded component 31 can be connected to the threaded post 32. The installation of the threaded component 31 and the threaded post 32 is simple and efficient. The edge of the mounting hole 23 may be provided with a first protrusion 25 facing the lamp plate 10. The first protrusion 25 can extend the mounting hole 23 and reduce the material used for the support component, thereby reducing costs. In this embodiment, the first protrusion 25 can abut against the base 322 of the screw hole post 32. The area of the base 322 is larger than the end area of the first protrusion 25, isolating the first protrusion 25 from the adhesive 13 and preventing the first protrusion from connecting with the adhesive 13. After the connecting component 30 is fixed to the support member 10, the support member 20 equipped with the connecting component 30 is obtained. The positions of each connecting component 30 on the support member 20 are relatively fixed, so there will be no situation where the position of individual connecting components (first connecting component or second connecting component) does not match the position of other connecting components. Next, the lamp panel 10 is placed horizontally with the third surface 11 (mounting surface) of the lamp panel 10 facing upward; the support member 20 equipped with the connecting component 30 is placed above the lamp panel 10.
[0049] The mounting surface has several connection areas 111 corresponding to the positions of the second connector 32. Adhesive 13 is pre-applied to the connection areas 111 to prepare for subsequent bonding of the lamp panel 10 to the support. Please refer to... Figure 7 , Figure 7A schematic diagram of the connection areas 111 provided on the mounting surface (i.e., the third surface 11) of the lamp panel 10 is shown. The adhesive 13 provided on the mounting surface of the lamp panel 10 is located on each connection area 111, and the positions of the connection areas 111 correspond to the positions of the second connectors 32 provided on the support member 20. The correspondence between the positions of the connection areas 111 and the second connectors 32 does not imply a perfect match. In fact, when providing the adhesive 13, it is sufficient to ensure that each second connector 32 can be properly bonded to the mounting surface 11 through the adhesive 13, and that the bonding result meets the required bonding strength. This allows for a certain degree of misalignment between the second connectors 32 and the connection areas 111 during actual bonding. The mounting surface 11 is the corresponding surface on the lamp panel 10 when connecting the lamp panel 10 and the support member 20. It generally corresponds to the light-emitting surface on the lamp panel 10 (in this embodiment, the fourth surface 12 of the lamp panel, see reference). Figure 6 (As shown) In contrast, the light-emitting surface refers to the surface where the light-emitting chip is disposed. After the lamp board 10 is manufactured, its light-emitting surface is very flat and can be placed horizontally downwards.
[0050] Then, the second connector 32 is aligned with the adhesive 13, and the third surface 11 of the lamp panel 10 and the first surface 21 of the support member 20 are pressed together, so that the second connector 32 is bonded to the adhesive 13 while the support member 20 is not in contact with the adhesive 13. Each second connector 32 is bonded to the connection area 111 by the adhesive 13. After the adhesive 13 cures, the required lamp panel assembly can be formed. Since the support member 20 and the connector 30 are detachable, the lamp panel 10 and the support member 20 can also be detached after the adhesive 13 cures, so that the support member 20 can be separated from the lamp panel 10.
[0051] In this embodiment, to allow for a certain gap between the second connector 32 and the lamp plate 10 during the pressing process to accommodate the adhesive 13, the support member 20 is provided with a second protrusion 24 facing the lamp plate 10. The second protrusion 24 is the part of the support member 20 closest to the lamp plate 10, and the distance from the second protrusion 24 to the lamp plate 10 is greater than the distance from the second connector 32 to the lamp plate 10. In this embodiment, the second protrusion 24 contacts the lamp plate 10; in other embodiments, a gasket or other parts may be provided between the second protrusion 24 and the lamp plate 10. In this embodiment, the second protrusion 24 is strip-shaped, and there are multiple strips, located at the edge and middle of the support member 20, so that the force exerted by the first protrusion 24 on the lamp plate 10 is relatively uniform, and the first protrusion 24 can surround the edge of the lamp plate, providing dust protection for the edge portion of the lamp plate. In one embodiment, the second protrusion 24 may also be columnar (e.g., cylindrical or prismatic) and distributed on the first surface 21 of the support member 20 (i.e., gaps for air circulation are formed between each second protrusion), so that there is more space between the support member 20 and the lamp panel 10, which is beneficial to the heat dissipation of the lamp panel 10. Since the second protrusion 24 is the part closest to the lamp panel 10, the second protrusion 24 can provide a support point when pressing the lamp panel 10 and the support member 20, so as to avoid the second connector 32 from excessively squeezing the adhesive 13, so that the adhesive 13 has a certain thickness, ensuring the bonding strength between the adhesive 13 and the lamp panel 10 and the second connector, and reducing the adhesive overflowing to the periphery of the second connector 32. Because the adhesive 13 has a certain accommodating space and good plasticity, even if the bottom or connection area of the second connector is uneven, it will not affect the accuracy of the connection between the second connector 32 and the first connector 31. As long as the position and posture of the first connector 31 and the second connector 32 are correct in advance, the adhesive 13 can maintain the accuracy of the connection between the first connector 31 and the second connector 32 after curing. Therefore, the plasticity of the adhesive 13 reduces the error rate in the bonding process.
[0052] In another embodiment, such as Figure 5b As shown, the third surface 11 (mounting surface) of the lamp panel 10 can also be placed downwards; the support member 20 equipped with the connecting assembly 30 is placed below the lamp panel 10. The first surface 21 of the support member 20 is placed horizontally, and then adhesive 13 is pre-applied to the bottom of the second connecting member 32 before pressing the lamp panel 10 and the support member 20 together. After the adhesive 13 has cured, the lamp panel assembly 1 can also be obtained.
[0053] The purpose of the adhesive 13 is to bond the lamp panel 10 to the support member 20. To maintain the flatness of the lamp panel 10, the adhesive 13 in this embodiment of the invention has a certain thickness. This structure allows the adhesive 13 to adapt to different orientations of the second connector and the mounting surface without affecting the flatness of the lamp panel 10. Specifically, the thickness of the adhesive 13 is greater than or equal to a first preset threshold, allowing the second connector 32 on the support member 20 to fully contact the adhesive 13 during assembly. In this case, even if the second connector 32 is tilted or misaligned with its corresponding preset mounting area, it can still be bonded normally to the second connector 32 using the adhesive. After bonding, the relative positions of all the second connectors 32 are fixed.
[0054] In some optional embodiments, to reduce the risk of excessive adhesive 13 overflowing, the thickness of the adhesive 13 applied to each preset connection area 111 of the mounting surface 11 can be set to be less than or equal to a second preset threshold. The second preset threshold is greater than the first preset threshold. Setting an upper limit for the thickness of the adhesive 13 is to prevent excessive application of adhesive 13, which could cause a large amount of adhesive 13 to overflow from the preset connection area 111 during bonding, affecting the function of other components of the lamp board 10. In addition to setting an upper limit for the thickness of the adhesive 13, to reduce the possibility of overflow, a first adhesive receiving groove 112 (see reference) can be provided in the connection area 111. Figure 5b In other words, some recesses are provided at the bottom of the connection area 111 to hold the adhesive 13 and restrict its flow. The first adhesive groove 112 allows the adhesive 13 to have a certain thickness, which can enhance the adhesion between the adhesive 13 and the lamp board 10 and the second connector 32. To reduce the possibility of adhesive overflow, a second adhesive groove 213 can also be provided at the bottom of the second connector 32 (see reference). Figure 5a and Figure 6 This means that some recesses are provided at the bottom of the second connector 32, so that excess adhesive 13 can be placed in the recesses and the adhesive 13 will be reduced from overflowing outward as the second connector 32 is squeezed. The shape of the recesses can be one of the following: "I", "+", circle, ellipse, wave, dot matrix, etc. The recesses can also increase the bonding surface between the adhesive 13 and the second connector 32, thereby enhancing the adhesion between the adhesive 13 and the lamp board 10 and the second connector 32.
[0055] Another optional embodiment of the present invention provides a method for assembling a lamp panel assembly. The lamp panel assembly produced by this method can significantly reduce the error rate in lamp panel assembly, lower production costs, and improve production efficiency. This lamp panel assembly method can also be used to assemble the aforementioned lamp panel assembly. For ease of understanding, the lamp panel assembly method is illustrated below. Please refer to... Figure 8 The method includes the following steps:
[0056] S101, Reference Figure 4 The system provides a support member 20, a lamp panel 10, and a connecting assembly 30. The connecting assembly 30 includes a first connector 31 and a second connector 32. The support member 20 has a first surface 21 and a second surface 22 facing each other. The lamp panel 10 has a third surface 11 and a fourth surface 12 facing each other. The support member 20 is provided with mounting holes 23 that penetrate the first surface 21 and the second surface 22 of the support member.
[0057] S102, Reference Figure 5a The first connector 31 is pre-connected by passing through the mounting hole 23 and detachably fixed to the second connector 32, and the second connector 32 is installed on the first surface 21;
[0058] This step involves detachably fixing the connecting component 30 corresponding to the mounting hole 22 to the support member 20; the connecting component 30 includes a first connecting member 31 disposed on one of the two opposing surfaces of the support member 20, and a second connecting member 32 disposed on the other surface; the first connecting member 31, the second connecting member 32, and the support member 20 are detachably fixedly connected based on the mounting hole 22.
[0059] refer to Figure 5a and Figure 5b An adhesive 13 corresponding to the position of the second connector 32 is pre-applied on the third surface 11, or an adhesive 13 is applied to the second connector 32.
[0060] In this step, adhesive 13 is pre-applied on the connection areas 111 corresponding to the position of the second connector 32 on the third surface 11 of the lamp panel 10 or on the second connector 20, so that the lamp panel 10 and the second connector 32 of the support member 20 can be bonded together by the adhesive 13. In this step, it is preferable that the thickness of the adhesive 13 is greater than or equal to a first preset threshold and less than a second threshold.
[0061] S103, Reference Figure 5a and Figure 5b Press the third side of the lamp panel and the first side of the support member together so that the second connector 32 is bonded to the lamp panel by adhesive and the support member 20 is not in contact with the adhesive 13.
[0062] In this step, in order to reduce the deformation of the lamp plate 10 and the support member 20 during pressing, a uniform force is applied to the fourth surface 11 of the lamp plate 10 or the second surface 21 of the support member 20 during pressing.
[0063] S104, after curing adhesive 13, the light panel assembly is obtained (reference). Figure 1 , Figure 2 , Figure 3 and Figure 4 (As shown).
[0064] Specifically, in this step, after the adhesive 13 has cured, the first connector 31 and the second connector 32 can be separated, thereby removing the lamp panel 10 from the support 20 for easy maintenance.
[0065] The above are merely preferred embodiments of the present invention. It should be understood that the application of the present invention is not limited to the examples described above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
