Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a lamp assembly. Background Technology

[0002] Currently, in related technologies, the assembly of LED (Light Emitting Diode) anti-glare downlights mostly involves placing cup-shaped reflective paper inside the housing, then placing a diffuser plate inside, and finally assembling the plastic reflective cup and housing together. This involves high-precision tolerance matching of four materials. If the size of one component is too large, it can easily cause the cup-shaped reflective paper to deform under pressure, resulting in light spots. If the size is too small, the diffuser plate can easily loosen, affecting the texture. Therefore, this makes the installation difficult and results in low efficiency in the installation process. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, this utility model proposes a lighting component.

[0005] In view of the above, the present invention provides a lighting assembly. The lighting assembly includes a reflective diffusion assembly, which includes a first reflective component, a diffuser plate, and a second reflective component. The first reflective component includes a first body and a first limiting portion, the first limiting portion being connected to a first side of the first body; the diffuser plate abuts against the first side of the first body, and at least a portion of the first limiting portion extends to the side of the diffuser plate away from the first body; the second reflective component includes a second body and a mounting portion, the second body being located on the side of the diffuser plate away from the first body, and the mounting portion being arranged circumferentially along the second body and located between the diffuser plate and the first limiting portion.

[0006] In this technical solution, the lighting fixture assembly can be embedded in the ceiling as a light source for illumination. The lighting fixture assembly includes a reflective diffusion assembly, which comprises a first reflective component, a diffusion plate, and a second reflective component. The second reflective component is reflective paper with a high emissivity. It reflects the light generated by the light source of the lighting fixture assembly, causing the light hitting the second reflective component to be reflected onto the diffusion plate. The diffusion plate disperses the light into a uniform surface light source, thereby eliminating glare. The first reflective component can control the direction of the light, achieving directional light distribution and preventing the light from directly hitting the eyes.

[0007] The first reflective component includes a first body and a first limiting part. The first limiting part is connected to a first side of the first body to realize the installation between the first limiting part and the first body.

[0008] The diffuser plate abuts against a first side of the first body, allowing the first side of the first body to support the diffuser plate. Furthermore, the first side of the first body can also limit one side of the diffuser plate. At least a portion of the first limiting portion extends to the side of the diffuser plate away from the first body, allowing the first limiting portion to limit the other side of the diffuser plate.

[0009] The second reflective component includes a second body and a mounting portion. The second body is located on the side of the diffuser plate away from the first body, i.e., the diffuser plate is located between the first and second reflective components. The mounting portion is arranged circumferentially along the second body and is located between the diffuser plate and the first limiting portion to facilitate the mounting of the mounting portion. The mounting portion can extend circumferentially away from the axis of the second body. By placing the mounting portion between the diffuser plate and the first limiting portion, the first side of the first body and the first limiting portion can clamp the diffuser plate and the mounting portion, tightly connecting the diffuser plate and the mounting portion to achieve the mounting of the diffuser plate and the second reflective component. Therefore, by providing the first limiting portion on the first side of the first body, the assembly of the first reflective component, the diffuser plate, and the second reflective component is achieved, allowing the first reflective component, the diffuser plate, and the second reflective component to be fixed together to form an integrated structural component.

[0010] This application achieves a fixed connection between the first reflector, the diffuser plate, and the second reflector by providing a first limiting part on the first side of the first body of the first reflector. Therefore, when assembling the lamp assembly, it is not necessary to assemble the first reflector, the diffuser plate, and the second reflector into the lamp assembly housing separately. By fixing the first reflector, the diffuser plate, and the second reflector together before assembling them into the lamp assembly housing, the assembly of the four structural components—the first reflector, the diffuser plate, the second reflector, and the lamp assembly housing—through high-precision tolerance fitting is avoided. This reduces the assembly difficulty of the lamp assembly and improves assembly efficiency.

[0011] Specifically, by setting a first limiting part to form an integrated structural component of the first reflective component, the diffuser plate, and the second reflective component, it is possible to not only improve the assembly efficiency of the lamp assembly, but also avoid the problems of uneven structure caused by the deformation of the reflective paper due to pressure or the loosening of the diffuser plate, as well as the high tolerance and precision requirements. In the assembly of the lamp assembly of this application, the first reflective component, the diffuser plate, and the second reflective component are assembled into one piece through the first limiting part, and then installed with the housing of the lamp assembly. Therefore, when assembling the first reflective component, the diffuser plate, and the second reflective component with the housing, blind installation can be achieved. There is no need to consider the installation direction during installation, and the assembly is more flat, making the assembly of the lamp assembly simpler and more convenient, thereby improving the assembly efficiency and the appearance and quality reliability of the lamp assembly. Furthermore, the method of assembling the first reflective component, the diffuser plate, and the second reflective component together via the first limiting part, and then assembling them with the housing, has lower tolerance requirements compared to the method of "placing the cup-shaped reflective paper inside the housing, then placing the diffuser plate, and finally assembling it with the housing using a plastic reflective cup, which involves high-precision tolerance matching of four materials." This avoids the problem of light spots caused by the cup-shaped reflective paper being deformed due to pressure from an excessively large component, and also avoids the problem of the diffuser plate being loose and affecting the texture if the size of one component is too small. In addition, the method of assembling the first reflective component, the diffuser plate, and the second reflective component together via the first limiting part, and then assembling them with the housing, allows the diameter of the diffuser plate to be smaller than the diameter of the housing. Compared to the method of having the diffuser plate abut against the inner wall of the housing or having a larger diameter diffuser plate to ensure proper installation, this application can reduce the size of the diffuser plate, thereby saving material costs and reducing assembly costs.

[0012] In some technical solutions of this utility model, optionally, the first side of the first body and the first limiting part form a first slot, and the mounting part and at least part of the diffuser plate are located in the first slot.

[0013] In this technical solution, a first side and a first limiting portion of the first body form a first slot. The mounting portion and at least a portion of the diffuser plate are located within the first slot. That is, the first body and the first limiting portion form an installation space, allowing the second reflective component and the diffuser plate to be installed by placing the mounting portion and the diffuser plate within this space. By placing the mounting portion and the diffuser plate within the first slot, they are limited, preventing movement of the second reflective component and the diffuser plate in the axial direction of the diffuser plate, thus improving the stability of the second reflective component and the diffuser plate after installation. The arrangement of the mounting portion and at least a portion of the diffuser plate within the first slot also ensures the coaxiality of the first reflective component, the diffuser plate, and the second reflective component after assembly, preventing skewness.

[0014] In some technical solutions of this utility model, optionally, the first limiting part includes a supporting part and a clamping part. The supporting part is arranged circumferentially along one end of the first body near the diffuser plate; the clamping part is disposed on the supporting part, and the mounting part and the diffuser plate are clamped between the clamping part and the first body.

[0015] In this technical solution, the first limiting part includes a supporting part and a clamping part. The supporting part is arranged circumferentially along one end of the first body near the diffuser plate to realize the setting of the supporting part. The clamping part is disposed on the supporting part, and the clamping part can install and limit the second reflective component and the diffuser plate. By setting the clamping part on the supporting part, the mounting part and the diffuser plate are clamped between the clamping part and the first body, so that the supporting part can support the clamping part, so that the clamping part and the first body can stably clamp the mounting part and the diffuser plate, ensuring that the second reflective component and the diffuser plate fit tightly after assembly, and preventing the diffuser plate from loosening.

[0016] In some technical solutions of this utility model, optionally, the support part has a notch on the side away from the first body, the clamping part is located in the notch, and the clamping part first extends to the side away from the first body, and then extends into the first body.

[0017] In this technical solution, the support portion has a notch on the side away from the first body, and the clamping portion is located within the notch to achieve the arrangement of the clamping portion. By placing the clamping portion within the notch, excessive space is avoided in the axial direction, reducing the axial dimension of the first limiting portion and allowing the first limiting portion to tightly connect the mounting portion and the diffuser plate together. The clamping portion extends first away from the first body and then into the first body to achieve the arrangement of the clamping portion. The way the clamping portion extends first away from the first body allows it to adapt to the thickness of the diffuser plate and the mounting portion, ensuring that the first limiting portion can install and limit the diffuser plate and the mounting portion. The extension of the clamping portion from the side away from the first body into the first body allows the clamping portion to axially limit the diffuser plate and the mounting portion, improving the stability after the diffuser plate and the mounting portion are installed.

[0018] Optionally, in some technical solutions of this utility model, the lamp assembly further includes a housing, the housing having a first cavity with an opening at one end, a reflective diffusion assembly disposed in the first cavity, a first body arranged close to the opening on the side away from the diffusion plate and detachably connected to the housing, and a second body abutting or connecting to the side of the first cavity facing the opening at the end away from the diffusion plate.

[0019] In this technical solution, the lighting assembly also includes a housing. The housing has a first cavity with an opening at one end. The opening allows for the installation of components located within the first cavity and also serves as the light-emitting end of the lighting assembly, thereby enabling illumination. A reflective diffuser assembly is disposed within the first cavity, facilitating the assembly of the lighting assembly and protecting the reflective diffuser assembly from the housing. A first body is positioned near the opening on the side away from the diffuser plate and is detachably connected to the housing. A second body, on the side away from the diffuser plate, abuts against or connects to the side of the first cavity facing the opening, thereby enabling the installation of the first and second reflective components with the housing. Since the first reflective component, the diffuser plate, and the second reflective component are integrally assembled via a first limiting part, the assembly of the housing, the first reflective component, the diffuser plate, and the second reflective component can be achieved through the assembly of the first reflective component with the housing, thus improving the assembly efficiency of the housing, the first reflective component, the diffuser plate, and the second reflective component.

[0020] In some technical solutions of this utility model, optionally, the lamp assembly further includes a light source plate, which is disposed in the first cavity and located between the bottom wall of the housing and the second body. The side of the second body away from the mounting part abuts or connects with the light source plate, and the light-emitting area of ​​the light source plate is located in the second body.

[0021] In this technical solution, the lighting assembly also includes a light source plate, which is disposed within the first cavity and located between the bottom wall of the housing and the second body to enable the installation and fixation of the light source plate, allowing the housing to protect the light source plate. The light source plate has a light source that can emit light, thereby enabling the lighting assembly to have an illumination function. The side of the second body away from the mounting part abuts against or connects to the light source plate, and the light-emitting area of ​​the light source plate is located within the second body, so that the light generated by the light source in the light-emitting area can illuminate the second reflective component and propagate through the diffuser plate and the first reflective component, avoiding light loss and improving the luminous efficiency of the lighting assembly.

[0022] In some technical solutions of this utility model, optionally, the light source board includes a board body and a light-emitting component. The side of the board body opposite to the second body abuts against or connects to the bottom wall of the housing, and the light-emitting area is located on the other side of the board body; the light-emitting component is disposed in the light-emitting area.

[0023] In this technical solution, the light source board includes a board body and a light-emitting component. The side of the board body facing away from the second body abuts against or connects to the bottom wall of the housing, allowing the housing to fix the light source board. The light-emitting area is located on the other side of the board body, and the light-emitting component is disposed within the light-emitting area to achieve installation and fixation of the light-emitting component, which serves as the light source for the lamp assembly. By placing the light-emitting component within the light-emitting area, all the light generated by the light-emitting component can be contained within the second reflective component, thereby avoiding light loss.

[0024] Optionally, in some technical solutions of this utility model, the first reflective component further includes a first snap-fit ​​portion, which is disposed on the outer wall of the second side of the first body; the housing has a first mating portion on the side near the opening, which is located in the first cavity and is snapped into the first snap-fit ​​portion.

[0025] In this technical solution, the first reflective component further includes a first snap-fit ​​portion, which is disposed on the outer wall of the second side of the first body to achieve the arrangement of the first snap-fit ​​portion. The housing has a first mating portion on the side near the opening, located within the first cavity and at the opening of the housing. The first mating portion snaps into the first snap-fit ​​portion, allowing the first reflective component to be assembled with the housing. This snap-fit ​​method facilitates the installation and disassembly of the first reflective component, thereby facilitating the subsequent replacement or repair of the first reflective component, the diffuser plate, and the second reflective component. The snap-fit ​​connection between the first reflective component and the housing allows for locking without additional tools, resulting in a more stable connection and significantly improving assembly efficiency.

[0026] Optionally, in some technical solutions of this utility model, the lamp assembly further includes an adhesive part, and the first snap-fit ​​part and the first mating part are connected and fixed by the adhesive part.

[0027] In this technical solution, the lighting assembly also includes an adhesive portion. The first snap-fit ​​portion and the first mating portion are connected and fixed through the adhesive portion to achieve the arrangement of the adhesive portion. The first snap-fit ​​portion and the first mating portion can be further connected together through the adhesive portion, improving the assembly stability between the first reflective component and the housing. The further connection between the first reflective component and the housing through the adhesive portion, based on the snap-fit ​​connection, can prevent the first reflective component from detaching from the housing due to deformation caused by thermal expansion and contraction of the lighting assembly.

[0028] Optionally, in some technical solutions of this utility model, the lamp assembly further includes a clamping component, which is disposed on the outer wall of the housing and is rotatable relative to the housing.

[0029] In this technical solution, the lighting assembly also includes a clamping component, which is disposed on the outer wall of the housing. The clamping component is rotatable relative to the housing to achieve installation and fixation. By providing the clamping component on the housing, the lighting assembly can be assembled into the mounting holes in the ceiling. Since the clamping component can rotate relative to the housing, the lighting assembly can be disassembled and installed by rotating the clamping component to different positions.

[0030] In some technical solutions of this utility model, optionally, the inner diameter of the first body gradually increases along the direction from the first side to the second side of the first body; and the inner diameter of the second body gradually decreases along the direction from the first side to the second side of the second body.

[0031] In this technical solution, the inner diameter of the first body gradually increases from its first side to its second side to achieve the arrangement of the first body. Specifically, the first body has a structure with a larger diameter at one end and a smaller diameter at the other, resulting in a larger diameter at the light-emitting end of the first reflective component. The first body forms a diffused reflective cavity, which facilitates light diffusion and output to meet lighting requirements. Conversely, the inner diameter of the second body gradually decreases from its first side to its second side to achieve the arrangement of the second body. This tapered shape of the second body can collect emitted light, reduce dispersion, and improve light utilization.

Detailed Implementation

[0035] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] The following reference Figures 1 to 4 A lamp assembly 100 according to some embodiments of the present invention is described.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a lighting assembly 100. The lighting assembly 100 includes a reflective diffusion assembly 152, which includes a first reflective component 102, a diffuser plate 116, and a second reflective component 118. The first reflective component 102 includes a first body 104 and a first limiting portion 106, the first limiting portion 106 being connected to a first side of the first body 104; the diffuser plate 116 abuts against the first side of the first body 104, and at least a portion of the first limiting portion 106 extends to the side of the diffuser plate 116 away from the first body 104; the second reflective component 118 includes a second body 120 and a mounting portion 122, the second body 120 being located on the side of the diffuser plate 116 away from the first body 104, and the mounting portion 122 being arranged circumferentially along the second body 120 and located between the diffuser plate 116 and the first limiting portion 106.

[0039] In this embodiment, the lighting assembly 100 can be embedded in the ceiling as a light source for illumination. The lighting assembly 100 includes a reflective diffusion assembly 152, which comprises a first reflective component 102, a diffuser plate 116, and a second reflective component 118. The second reflective component 118 is reflective paper with a high emissivity. It reflects the light generated by the light source of the lighting assembly 100, causing the light hitting the second reflective component 118 to be reflected onto the diffuser plate 116. The diffuser plate 116 disperses the light into a uniform surface light source, thereby eliminating glare. The first reflective component 102 can control the direction of the light, achieving directional light distribution and preventing the light from directly hitting the eyes.

[0040] The first reflective component 102 includes a first body 104 and a first limiting part 106. The first limiting part 106 is connected to a first side of the first body 104 to realize the installation between the first limiting part 106 and the first body 104.

[0041] The diffuser plate 116 abuts against a first side of the first body 104, allowing the first side of the first body 104 to support the diffuser plate 116. Furthermore, the first side of the first body 104 can also limit one side of the diffuser plate 116. At least a portion of the first limiting portion 106 extends to the side of the diffuser plate 116 away from the first body 104, allowing the first limiting portion 106 to limit the other side of the diffuser plate 116.

[0042] The second reflective component 118 includes a second body 120 and a mounting portion 122. The second body 120 is located on the side of the diffuser plate 116 away from the first body 104, that is, the diffuser plate 116 is located between the first reflective component 102 and the second reflective component 118. The mounting portion 122 is arranged circumferentially along the second body 120 and is located between the diffuser plate 116 and the first limiting portion 106 to realize the arrangement of the mounting portion 122. The mounting portion 122 can extend circumferentially away from the axis of the second body 120. By placing the mounting portion 122 between the diffuser plate 116 and the first limiting portion 106, the first side of the first body 104 and the first limiting portion 106 can clamp the diffuser plate 116 and the mounting portion 122, so that the diffuser plate 116 and the mounting portion 122 are tightly connected together to realize the installation of the diffuser plate 116 and the second reflective component 118. Therefore, by providing a first limiting part 106 on the first side of the first body 104, the assembly of the first reflective component 102, the diffuser plate 116 and the second reflective component 118 can be realized, so that the first reflective component 102, the diffuser plate 116 and the second reflective component 118 can be fixed together to form an integrated structural component.

[0043] This application achieves a fixed connection between the first reflector 102, the diffuser 116, and the second reflector 118 by providing a first limiting part 106 on the first side of the first body 104 of the first reflector 102. Therefore, when assembling the lamp assembly 100, it is not necessary to sequentially assemble the first reflector 102, the diffuser 116, and the second reflector 118 into the housing 126 of the lamp assembly 100. By fixing the first reflector 102, the diffuser 116, and the second reflector 118 together before assembling them into the housing 126 of the lamp assembly 100, the assembly difficulty of the lamp assembly 100 and the assembly efficiency can be reduced by assembling the four structural components of the first reflector 102, the diffuser 116, the second reflector 118, and the housing 126 of the lamp assembly 100 with high-precision tolerance fitting.

[0044] Specifically, by setting the first limiting part 106 to form an integrated structural component of the first reflector 102, the diffuser plate 116, and the second reflector 118, it can not only improve the assembly efficiency of the lamp assembly 100, but also avoid the problems of uneven structure caused by the pressure and deformation of the reflective paper or the easy loosening of the diffuser plate 116, as well as the high tolerance and precision requirements. When assembling the lamp assembly 100 of this application, the first reflector 102, the diffuser plate 116, and the second reflector 118 are assembled into one piece through the first limiting part 106, and then installed with the housing 126 of the lamp assembly 100. Therefore, when assembling the first reflector 102, the diffuser plate 116, and the second reflector 118 with the housing 126, blind installation can be achieved. There is no need to consider the installation direction during installation, and the assembly is more flat, making the assembly of the lamp assembly 100 simpler and more convenient, thereby improving the assembly efficiency and the appearance and quality reliability of the lamp assembly 100. Furthermore, the method of assembling the first reflective component 102, the diffuser plate 116, and the second reflective component 118 together via the first limiting part 106 before assembling them with the housing 126 has lower tolerance requirements compared to the method of "placing the cup-shaped reflective paper inside the housing 126, then placing the diffuser plate inside, and finally assembling it with the housing 126 via the plastic reflective cup, which involves high-precision tolerance matching of four materials." This avoids the problem of light spots caused by the cup-shaped reflective paper being deformed due to pressure from an excessively large component, and also avoids the problem of the diffuser plate 116 being loose and affecting the texture if the size of one component is too small. In addition, the method of assembling the first reflective component 102, the diffuser plate 116, and the second reflective component 118 together via the first limiting part 106 before assembling them with the housing 126 allows the diameter of the diffuser plate 116 to be smaller than the diameter of the housing 126. Compared to the method of having the diffuser plate abut against the inner wall of the housing or having a larger diameter diffuser plate to ensure proper installation, this application can reduce the size of the diffuser plate 116, thereby saving material costs and reducing assembly costs.

[0045] Specifically, the first reflective component 102 is a reflective cup, and the second reflective component 118 is a cup-shaped reflective paper. The first reflective component 102 and the second reflective component 118 can reflect light, thereby controlling the transmission direction of light.

[0046] Specifically, the second reflective component 118 is reflective paper.

[0047] Specifically, the first reflective component 102 is a plastic reflective cup.

[0048] Specifically, the cup-shaped reflective paper and the diffuser plate 116 are assembled together by inverting the plastic reflective cup to form an integrated structural component. The assembled whole can be blindly assembled by the strong release snap of the inner ring of the shell 126, without the need for directionality, with interference fit assembly and additional glue fixation.

[0049] Specifically, in Figure 2 In the diagram, B represents the circumferential direction of the first body 104 and the circumferential direction of the second body 120.

[0050] Specifically, the inner walls of the first reflective component 102 and the second reflective component 118 both have reflective surfaces, which can reflect light and thus adjust the direction of light propagation.

[0051] In some embodiments of this utility model, optionally, such as Figure 2 and Figure 3 As shown, the first side of the first body 104 and the first limiting part 106 surround the first slot 146, and the mounting part 122 and at least part of the diffuser plate 116 are located in the first slot 146.

[0052] In this embodiment, a first groove 146 is formed by the first side of the first body 104 and the first limiting part 106. The mounting part 122 and at least a portion of the diffuser plate 116 are located within the first groove 146. That is, the first body 104 and the first limiting part 106 form an installation space, allowing the second reflective component 118 and the diffuser plate 116 to be installed by placing the mounting part 122 and the diffuser plate 116 within the installation space. By placing the mounting part 122 and the diffuser plate 116 within the first groove 146, the mounting part 122 and the diffuser plate 116 can be limited, preventing movement of the second reflective component 118 and the diffuser plate 116 in the axial direction of the diffuser plate 116, thereby improving the stability of the second reflective component 118 and the diffuser plate 116 after installation. The arrangement of mounting part 122 and at least part of diffuser plate 116 within first slot 146 also ensures coaxiality of the first reflective component 102, diffuser plate 116 and second reflective component 118 after assembly, and avoids skewing.

[0053] In some embodiments of this utility model, optionally, such as Figure 2 and Figure 4 As shown, the first limiting part 106 includes a support part 108 and a clamping part 110. The support part 108 is arranged circumferentially along one end of the first body 104 near the diffuser plate 116; the clamping part 110 is disposed on the support part 108, and the mounting part 122 and the diffuser plate 116 are clamped between the clamping part 110 and the first body 104.

[0054] In this embodiment, the first limiting part 106 includes a supporting part 108 and a clamping part 110. The supporting part 108 is arranged circumferentially along one end of the first body 104 near the diffuser plate 116 to realize the setting of the supporting part 108. The clamping part 110 is disposed on the supporting part 108, and the clamping part 110 can install and limit the second reflective component 118 and the diffuser plate 116. By disposing of the clamping part 110 on the supporting part 108, the mounting part 122 and the diffuser plate 116 are clamped between the clamping part 110 and the first body 104, so that the supporting part 108 can support the clamping part 110, so that the clamping part 110 and the first body 104 can stably clamp the mounting part 122 and the diffuser plate 116, ensuring that the second reflective component 118 and the diffuser plate 116 fit tightly after assembly, and preventing the diffuser plate 116 from loosening.

[0055] In some embodiments of this utility model, optionally, such as Figure 4 As shown, the support portion 108 has a notch 148 on the side away from the first body 104, and the clamping portion 110 is located in the notch 148. The clamping portion 110 first extends to the side away from the first body 104, and then extends into the first body 104.

[0056] In this embodiment, the support portion 108 has a notch 148 on the side away from the first body 104, and the clamping portion 110 is located within the notch 148 to achieve the arrangement of the clamping portion 110. By placing the clamping portion 110 within the notch 148, excessive space occupied by the clamping portion 110 in the axial direction can be avoided, reducing the axial dimension of the first limiting portion 106, allowing the first limiting portion 106 to tightly connect the mounting portion 122 and the diffuser plate 116 together. The clamping portion 110 extends first to the side away from the first body 104, and then extends into the first body 104 to achieve the arrangement of the clamping portion 110. The way the clamping portion 110 extends first to the side away from the first body 104 allows the clamping portion 110 to adapt to the thickness of the diffuser plate 116 and the mounting portion 122, ensuring that the first limiting portion 106 can install and limit the diffuser plate 116 and the mounting portion 122. The clamping part 110 extends into the first body 104 from the side away from the first body 104, so that the clamping part 110 can axially limit the diffuser plate 116 and the mounting part 122, thereby improving the stability of the diffuser plate 116 and the mounting part 122 after installation.

[0057] In some embodiments of this utility model, optionally, such as Figure 1 , Figure 2 and Figure 3As shown, the lighting assembly 100 also includes a housing 126, which has a first cavity 142 with an opening 144 at one end. A reflective diffusion assembly 152 is disposed in the first cavity 142. A first body 104 is arranged near the opening 144 on the side away from the diffuser plate 116 and is detachably connected to the housing 126. The end of a second body 120 away from the diffuser plate 116 abuts against or is connected to the side of the first cavity 142 facing the opening 144.

[0058] In this embodiment, the lighting assembly 100 further includes a housing 126. The housing 126 has a first cavity 142 with an opening 144 at one end. The opening 144 allows for the installation of components located within the first cavity 142, and the opening 144 is also the light-emitting end of the lighting assembly 100, thereby achieving illumination of the lighting assembly 100. A reflective diffusion assembly 152 is disposed within the first cavity 142, thereby enabling the assembly of the lighting assembly 100 and allowing the housing 126 to protect the reflective diffusion assembly 152. The side of the first body 104 away from the diffuser plate 116 is arranged near the opening 144 and is detachably connected to the housing 126. The end of the second body 120 away from the diffuser plate 116 abuts against or connects to the side of the first cavity 142 facing the opening 144, thereby enabling the installation of the first reflective component 102 and the second reflective component 118 between themselves and the housing 126. Since the first reflective component 102, the diffuser plate 116, and the second reflective component 118 are integrally assembled through the first limiting part 106, the assembly of the housing 126, the first reflective component 102, the diffuser plate 116, and the second reflective component 118 can be achieved through the assembly between the first reflective component 102 and the housing 126, thereby improving the assembly efficiency between the housing 126, the first reflective component 102, the diffuser plate 116, and the second reflective component 118.

[0059] In some embodiments of this utility model, optionally, such as Figure 2 As shown, the lighting assembly 100 also includes a light source plate 130, which is disposed in the first cavity 142 and located between the bottom wall of the housing 126 and the second body 120. The side of the second body 120 away from the mounting part 122 is connected to or abuts against the light source plate 130, and the light-emitting area 140 of the light source plate 130 is located in the second body 120.

[0060] In this embodiment, the lighting assembly 100 further includes a light source plate 130, which is disposed within the first cavity 142 and located between the bottom wall of the housing 126 and the second body 120, to achieve the installation and fixation of the light source plate 130, so that the housing 126 can protect the light source plate 130. The light source plate 130 has a light source that can emit light, thereby enabling the lighting assembly 100 to have an illumination function. The side of the second body 120 away from the mounting part 122 abuts against or connects to the light source plate 130, and the light-emitting area 140 of the light source plate 130 is located within the second body 120, so that the light generated by the light source in the light-emitting area 140 can illuminate the second reflector 118 and propagate through the diffuser 116 and the first reflector 102, avoiding light loss and improving the luminous efficiency of the lighting assembly 100.

[0061] In some embodiments of this utility model, optionally, such as Figure 2 As shown, the light source board 130 includes a board body 132 and a light-emitting component 134. The side of the board body 132 facing away from the second body 120 abuts against or is connected to the bottom wall of the housing 126, and the light-emitting area 140 is located on the other side of the board body 132; the light-emitting component 134 is disposed in the light-emitting area 140.

[0062] In this embodiment, the light source board 130 includes a board body 132 and a light-emitting component 134. The side of the board body 132 facing away from the second body 120 abuts against or connects to the bottom wall of the housing 126, so that the housing 126 can fix the light source board 130. The light-emitting area 140 is located on the other side of the board body 132, and the light-emitting component 134 is disposed in the light-emitting area 140 to realize the installation and fixation of the light-emitting component 134, which is the light source of the lamp assembly 100. By disposing of the light-emitting component 134 in the light-emitting area 140, all the light generated by the light-emitting component 134 can be located within the second light-emitting component 134, thereby avoiding light loss.

[0063] Specifically, the light-emitting component 134 is an LED lamp bead, which can emit light for illumination.

[0064] Specifically, there are multiple light-emitting components 134, which are evenly arranged within the light-emitting area 140.

[0065] In some embodiments of this utility model, optionally, such as Figure 1 and Figure 2 As shown, the first reflective component 102 also includes a first snap-fit ​​portion 112, which is disposed on the outer wall of the second side of the first body 104; the housing 126 has a first mating portion 128 on the side near the opening 144, which is located inside the first cavity 142 and is snapped into the first snap-fit ​​portion 112.

[0066] In this embodiment, the first reflective component 102 further includes a first snap-fit ​​portion 112, which is disposed on the outer wall of the second side of the first body 104 to facilitate its arrangement. The housing 126 has a first mating portion 128 on the side near the opening 144. The first mating portion 128 is located within the first cavity 142 and at the opening 144 of the housing 126. The first mating portion 128 engages with the first snap-fit ​​portion 112, allowing the first reflective component 102 to be assembled with the housing 126. This snap-fit ​​method facilitates the installation and disassembly of the first reflective component 102, thereby facilitating the replacement or repair of the first reflective component 102, the diffuser plate 116, and the second reflective component 118 later. The snap-fit ​​connection between the first reflective component 102 and the housing 126 eliminates the need for additional tools, resulting in a more stable connection and significantly improving assembly efficiency.

[0067] Specifically, the first snap-fit ​​part 112 is a flanged structure, the first mating part 128 is a second snap-fit ​​groove, the second snap-fit ​​groove is arranged along the circumference of the housing 126, and the flanged structure snaps into the second slot so that the first reflective component 102 can be assembled with the housing 126.

[0068] In some embodiments of this utility model, optionally, such as Figure 2 As shown, the lighting assembly 100 also includes an adhesive portion 136, through which the first snap-fit ​​portion 112 and the first mating portion 128 are connected and fixed.

[0069] In this embodiment, the lamp assembly 100 further includes an adhesive portion 136. The first snap-fit ​​portion 112 and the first mating portion 128 are connected and fixed through the adhesive portion 136 to achieve the arrangement of the adhesive portion 136. The first snap-fit ​​portion 112 and the first mating portion 128 can be further connected together through the adhesive portion 136, improving the stability of the assembly between the first reflective component 102 and the housing 126. The further connection of the first reflective component 102 and the housing 126 through the adhesive portion 136, based on the snap-fit ​​connection, can prevent the lamp assembly 100 from deforming due to thermal expansion and contraction, thus avoiding the detachment of the first reflective component 102 from the housing 126.

[0070] Specifically, the adhesive portion 136 includes adhesive. There are multiple adhesive portions 136, which are arranged at intervals along the circumference of the housing 126, thereby further improving the stability of the first light-emitting component 134 after assembly with the housing 126.

[0071] In some embodiments of this utility model, optionally, such as Figure 1 and Figure 2As shown, the lighting assembly 100 also includes a clamping member 138, which is disposed on the outer wall of the housing 126 and is rotatable relative to the housing 126.

[0072] In this embodiment, the lighting assembly 100 further includes a clamping member 138, which is disposed on the outer wall of the housing 126. The clamping member 138 is rotatable relative to the housing 126 to achieve installation and fixation of the clamping member 138. By providing the clamping member 138 on the housing 126, the lighting assembly 100 can be assembled into the mounting hole in the ceiling. Since the clamping member 138 is rotatable relative to the housing 126, the lighting assembly 100 can be disassembled and installed by rotating the clamping member 138 to different positions.

[0073] In some embodiments of this utility model, optionally, such as Figure 2 As shown, the second reflective component 118 has a second cavity 124, the first reflective component 102 has a third cavity 114, and the diffuser plate 116 is located between the second cavity 124 and the third cavity 114.

[0074] In this embodiment, the second reflector 118 has a second cavity 124, the first reflector 102 has a third cavity 114, and a diffuser plate 116 is located between the second cavity 124 and the third cavity 114 to separate the second cavity 124 and the third cavity 114. The light generated by the light source of the lamp assembly 100 illuminates the second cavity 124, undergoes initial reflection and mixing within the second cavity 124, is then homogenized by the diffuser plate 116, and finally undergoes secondary emission and extraction within the third cavity 114. This results in more uniform and softer light, improving the quality of the emitted light.

[0075] In some embodiments of this utility model, optionally, such as Figure 1 , Figure 2 and Figure 4 As shown, the inner diameter of the first body 104 gradually increases along the direction from the first side to the second side of the first body 104; and the inner diameter of the second body 120 gradually decreases along the direction from the first side to the second side of the second body 120.

[0076] In this embodiment, the inner diameter of the first body 104 gradually increases from its first side to its second side to achieve an arrangement where the first body 104 has a larger diameter at one end and a smaller diameter at the other. This results in a larger diameter at the light-emitting end of the first reflective component 102, and the first body 104 forms a diffused reflective cavity, which facilitates light diffusion and output to meet lighting requirements. The inner diameter of the second body 120 gradually decreases from its first side to its second side to achieve an arrangement where the second body 120 is positioned correctly. The tapered shape of the second body 120 can collect emitted light, reduce dispersion, and improve light utilization.

[0077] Specifically, the light-incident end of the first body 104 is located on the first side of the first body 104, that is, the light-incident end of the first body 104 is located on the side close to the diffuser plate 116; the light-exiting end of the first body 104 is located on the second side of the first body 104, that is, the light-exiting end of the first body 104 is located on the side away from the diffuser plate 116, at the position of the opening 144 of the housing 126.

[0078] Specifically, the light-incident end of the second body 120 is located on the second side of the second body 120, that is, the light-incident end of the second body 120 faces the light-emitting area 140 of the housing 126; the light-emitting end of the second body 120 is located on the first side of the second body 120, that is, near the diffuser plate 116.

[0079] Specifically, the lighting assembly 100 is an LED anti-glare downlight.

[0080] Specifically, a first limiting part 106 is provided on the first side of the first body 104. The first side of the first body 104 is the bottom of the plastic reflector cup, that is, an inverted buckle is made evenly at the bottom of the plastic reflector cup. The diffuser plate 116 and the cup-shaped reflective paper are assembled with the plastic reflector cup by the inverted buckle to form an integrated structure. This avoids the four structural components of the cup-shaped reflective paper, diffuser plate 116, reflector cup and housing 126 of lamp assembly 100 being assembled by high-precision tolerance fit. A ring of inverted buckles that can be strongly detached is provided inside the top of the housing 126. By assembling and cooperating with the plastic reflector cup with the inverted buckle set in the housing 126, blind assembly of the lamp assembly 100 can be realized without considering the direction of assembly. Then, the plastic reflector cup is assembled with the housing 126 by interference fit, and the plastic reflector cup and the housing 126 are fixed by auxiliary glue application to achieve uniform and flat mounting surfaces between the various components.

[0081] Specifically, the lighting assembly 100 also includes a cable 150, which is connected to the light source board 130 so as to provide power to the light source board 130.

[0082] Specifically, in Figure 2In the diagram, C represents the inner diameter of the first body 104, and D represents the inner diameter of the second body 120.

[0083] Specifically, the inner diameters of the first body 104 and the second body 120 are both smaller than the inner diameter of the housing 126. Therefore, the inner diameter of the first side of the first body 104 is smaller than the inner diameter of the housing 126. Since the diffuser plate 116 is installed on the first side of the first body 104, the diameter of the diffuser plate 116 is smaller than the inner diameter of the housing 126. Compared with the method where the edge of the diffuser plate 116 contacts the inner wall of the housing 126, the material cost of the diffuser plate 116 can be reduced, thereby reducing the cost.
