Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of lighting device, concretely relates to a face frame structure and panel lamp. BACKGROUND

[0002] Panel lamp is widely used in office, factory and warehouse space as the basic lighting equipment of large area space. With the increase of lighting space, the illumination area of single panel lamp is gradually increased. Among them, the diffusion plate is an important component for light softening and protecting the light emitting element of the panel lamp. With the increase of the illumination area, its area also increases.

[0003] At present, the diffusion plate is clamped between the lamp body and the face frame by screws in the structure of the panel lamp. However, in practical application, the diffusion plate will sag obviously due to the material characteristics and the center of gravity in suspension when the diffusion plate area is increased. Secondly, when fixed by multiple screws, the face frame will produce local deformation when pressed or tightened by the screw, and the clamping force of the diffusion plate is not uniformly distributed, which will also cause the local deformation and sagging of the diffusion plate after installation. The sagging of the diffusion plate leads to uneven light output and other problems, affecting the light output quality of the panel lamp.

[0004] In order to solve the above problems, the thickness of the diffusion plate is usually increased to achieve better rigidity, so that the clamping is more stable and the sagging of the diffusion plate is reduced. However, the increase of thickness will reduce the light transmittance, which will reduce the energy efficiency of the actual panel lamp. Or by thickening the face frame, using aluminum profile and other ways to strengthen the rigidity and strength of the face frame, to reduce the problem of local sagging deformation of the diffusion plate. But this scheme increases the production cost and inhibits the demand for large panel lamps. SUMMARY

[0005] In order to solve the problems of the prior art, the utility model provides a face frame structure and panel lamp, which is fixedly connected with the diffusion plate and the edge strip by assembling the edge strip and the corner code and adopting the connecting structure to form an integrated structure, which greatly reduces the sagging of the diffusion plate and reduces the production cost.

[0006] The technical effects achieved by the utility model are realized by the following technical aspects:

[0007] In the first aspect, the utility model provides a face frame structure, which comprises:

[0008] The edge strip, a plurality of edge strips surround the light output area, the edge strip comprises a base body and a support part, the support part extends from the bottom of the base body to the light output area, and the base body is provided with a plug-in hole at both ends;

[0009] Angle bracket, having a flat structure, is provided with two insertion parts, which are inserted into the insertion holes to lock and fix two adjacent edge strips; and

[0010] A diffuser plate is disposed within the light-emitting area and located on the support portion;

[0011] The support portion has a connecting structure on the side facing the diffuser plate, and the diffuser plate is fixedly connected to the edge strip through the connecting structure to form an integral structure.

[0012] In some implementations, the connection structure is an ultrasonic welding structure or an adhesive structure.

[0013] In a further implementation, the ultrasonic welding structure is a rib that runs through the entire support and protrudes towards the light-emitting area;

[0014] The adhesive structure is a groove that runs horizontally through the entire support and is recessed downwards.

[0015] In some implementations, the two connectors in the corner bracket are arranged perpendicularly to each other.

[0016] In some implementations, the plug-in portion includes an insertion end and a locking end, the end face of the insertion end is a smooth arc surface, and the locking end is provided with an elastic zone and a clearance zone.

[0017] In some implementations, the diffuser plate is a flexible plastic part with a plate-like structure, the surface of the diffuser plate has a corrugated structure, and the thickness of the diffuser plate is less than 0.8 mm.

[0018] In some implementations, the edge strip is an injection-molded part, and the corner bracket is a rigid plastic part or a metal part.

[0019] Secondly, this utility model provides a panel light, including a lamp body, a light-emitting component, and any of the above-described face frame structures;

[0020] The lamp body has a light-emitting cavity and an edge surrounding the end of the light-emitting cavity. The light-emitting component is fixedly installed in the light-emitting cavity, and the light-emitting cavity faces the light-emitting area. The base has a top surface, which is located on the side opposite to the bottom of the base. The edge is fixed to the top surface.

[0021] In some implementations, the lamp body further includes a pressing part, which is disposed on the side of the edge facing the light-emitting cavity. When the edge abuts against and is fixed to the top surface, the pressing part presses against the diffuser plate.

[0022] In some implementations, a fastener is also included, and the base is further provided with a slot, which is disposed between the insertion hole and the support portion, and the fastener passes through the edge and is locked and fixed in the slot.

[0023] In summary, this utility model has at least the following advantages:

[0024] 1. The face frame structure provided by this utility model fixes the diffuser plate and the edge strips together to form an integrated structure through a connecting structure, achieving a tight connection between the edge strips. Simultaneously, the connecting structure ensures stable and uniform stress on the connection between the edge strips and the diffuser plate, and the sag of the diffuser plate is controllable and reduced. Furthermore, the choice of diffuser plate thickness is opposite to existing technologies; the larger the diffuser plate area, the thinner the thickness is required, reducing the stress on the diffuser plate from the connecting structure and significantly reducing the sag of the diffuser plate due to gravity deformation.

[0025] 2. The face frame structure provided by this utility model allows for standardized molding and assembly of the edge strips and corner brackets. As the area of ​​the diffuser plate increases, its thickness needs to be reduced. The fixed connection between the edge strips and the diffuser plate, forming an integrated structure, can be completed during the panel light production stage. While significantly reducing sag, the face frame structure offers higher production efficiency and lower cost compared to existing technologies, making it easier to promote and use.

[0026] 3. The panel light provided by this utility model adopts the above-mentioned frame structure. During the installation process, there is no need to adjust the fixing of the diffuser plate; simply lock the frame structure to the panel light, which greatly reduces installation time. Furthermore, because the diffuser plate is integrally fixed to the edge strip, the diffuser plate does not gradually shift or sag due to aging, thus improving the service life of the panel light.

[0050] 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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0051] Example 1

[0052] Please see Figures 1-3 This embodiment provides a face frame structure 100, installed on the light-emitting side of a panel light, to process and emit the strong light from the light-emitting component during operation towards the space requiring illumination. The face frame structure 100 includes side strips 1, corner brackets 2, and diffuser plates 3. Multiple side strips 1 surround to form a light-emitting area 4, and each side strip 1 has the same cross-section, including a base 11 and a support portion 12. The support portion 12 extends from the bottom 111 of the base 11 toward the light-emitting area 4.

[0053] Please Figures 1-3 Based on this, refer to Figure 4 The base 11 has insertion holes 112 at both ends. Generally, in order to reduce the weight of the edge strip 1, improve the structural strength of the edge strip 1, and ensure the structural consistency of the edge strip 1, the two insertion holes 112 of the base 11 are connected through each other and formed in one piece.

[0054] Continue reading Figures 1-3 The corner bracket 2 has a flat structure and is positioned between two adjacent edge strips 1. Each corner bracket 2 has two insertion parts 21, which are inserted into the insertion holes 112 to lock and fix the two adjacent edge strips 1 in a precise position.

[0055] The diffuser plate 3 is disposed within the light-emitting area 4 and is located on the support part 12. The diffuser plate 3 processes the original light source of the panel light before emission, so that the final emitted light of the panel light meets the requirements of the lighting design.

[0056] In this embodiment, there are four edge strips 1, and the diffuser plate 3 is a matching quadrilateral. The support 12 has a connecting structure 121 on the side facing the diffuser plate 3. The diffuser plate 3 is fixedly connected to the edge strips 1 via the connecting structure 121 to form an integral structure. That is, the four sides of the diffuser plate 3 interact with the connecting structures 121 on the four edge strips 1, forming an integral unit through the connecting structures 121. The two opposing pairs of edge strips 1 are "pulled" by the diffuser plate 3, and combined with the corner brackets 2, all edge strips 1 are completely fixed, forming a whole without the need for additional accessories. This reduces the process structure and lowers the overall cost. The multiple edge strips 1 pull the diffuser plate 3 in opposite directions, keeping the diffuser plate 3 in a "taut" state, significantly reducing the sagging near the center of the diffuser plate 3. Compared to the current method of fixing the diffuser plate 3 with screws and other fasteners, the mechanical effect is superior, and the connected state is more stable.

[0057] Secondly, the thickness selection of the diffuser plate 3 is also contrary to the existing technology. Because it is being "pulled" by multiple edge strips 1, the sag of the suspended portion of the diffuser plate 3 is significantly affected by the gravity at various points on the diffuser plate 3. Ideally, to reduce sag, the thickness should be thinner closer to the center of the diffuser plate 3. However, in actual production, considering factors such as cost and process difficulty, the thickness of a single diffuser plate 3 is generally not produced in a gradual manner, but rather a uniformly thinner production scheme is adopted. After the diffuser plate 3 is made thinner, the force between the diffuser plate 3 and the connecting structure 121 is also relatively reduced, allowing the area of ​​the diffuser plate 3 to be further increased. Reducing the sag of the diffuser plate 3 also reduces material costs. Simultaneously, it improves the light transmittance of the diffuser plate 3.

[0058] It should be noted that in existing technologies, the thickness of the diffuser plate 3 can also be reduced to achieve a certain reduction in sagging. However, because the diffuser plate 3 is made thinner, when fastening the diffuser plate 3, the thinner diffuser plate 3 deforms less under the same locking force than the thicker diffuser plate 3, resulting in a reduced actual locking effect. Combined with uneven force during assembly and the fact that the diffuser plate 3 becomes "softer" overall due to its thinner thickness, this can actually increase the local sagging problem.

[0059] During production, both the edge strip 1 and the corner bracket 2 can be standardized. For example, the edge strip 1 can be formed by die casting or injection molding, and then cut and spliced ​​according to the required length. The corner bracket 2 can be mass-produced by stamping or injection molding, effectively reducing costs and allowing for mass production of spare parts. When manufacturing the face frame structure 100, the edge strip 1 can be customized to achieve different required shapes and sizes. The integrated fixing of the edge strip 1 and the diffuser plate 3 can be completed during the processing stage. While significantly reducing sagging, the face frame structure 100 described in this embodiment obviously has higher assembly efficiency and lower cost compared to existing face frames.

[0060] In this embodiment, the connecting structure 121 is either an ultrasonic welding structure 1211 or an adhesive structure 1212. Specifically, the ultrasonic welding structure 1211 is a rib that runs through the entire support portion 12 and protrudes towards the light-emitting area 4. The adhesive structure 1212 is a groove that runs through the entire support portion 12 and is recessed downwards.

[0061] If ultrasonic welding structure 1211 is used, such as Figure 5 As shown, the upper part is a schematic diagram before ultrasonic welding, and the lower part is a schematic diagram after ultrasonic welding. After the edge strip 1 and the corner bracket 2 are assembled, the edge strip 1 and the diffuser plate 3 are ultrasonically welded using an ultrasonic generator. The diffuser plate 3 is fixedly connected to the support part 12 around its perimeter, forming an integral structure that is reliable and stable. However, if an adhesive structure 1212 is used, such as... Figure 6 As shown, adhesive compatible with the materials of the diffuser plate 3 and the edge strip 1 can be added to the bonding structure 1212 for bonding, or the diffuser plate 3 can be heated and bonded into the bonding structure 1212. Of course, the bonding structure 1212 can be constructed as follows: Figure 6 The inverted T-shaped structure shown makes the adhesive less likely to fall off even after prolonged use, once it has solidified.

[0062] By using an ultrasonic welding structure 1211 or an adhesive structure 1212 that runs through the entire support section 12, it is possible to ensure that the fixed connection between the diffuser plate 3 and the edge strip 1 is continuous, so that the connection position forms a linear or planar stress range, resulting in a more stable and uniform stress state.

[0063] Obviously, in addition to the two solutions mentioned above, high-frequency heating and other processes can also be used. Since there are many ways to fix the components together, they will not be listed here.

[0064] To ensure an aesthetically pleasing connection between edge strips 1, the insertion holes 112 are interconnected in adjacent edge strips 1, and corner brackets 2 are installed within the adjacent edge strips 1 through the insertion holes 112. Corner brackets 2 serve to position, partially fix, and lock the connection during assembly. Concealing corner brackets 2 within the edge strips 1 not only enhances the appearance but also effectively connects the ultrasonic welding structures 1211 or adhesive structures 1212 of each edge strip 1 end-to-end. Compared to bonding adjacent edge strips 1 together, this connection is more secure and easier to manufacture and assemble.

[0065] like Figure 7 As shown, the corner bracket 2 is L-shaped, with insertion parts 21 respectively disposed on both sides of the L-shaped structure. In this embodiment, the two insertion parts 21 in a single corner bracket 2 are arranged perpendicularly to each other, ensuring that adjacent edge strips 1 form a right angle when the insertion parts 21 are inserted into the insertion holes 112. To ensure quick and stable insertion of the insertion parts 21 into the insertion holes 112, the insertion parts 21 include an insertion end 211 and a locking end 212. In the corner bracket 2, the two locking ends 212 are connected, and the insertion end 211 is disposed at the end of the locking end 212. In application, the end face of the insertion end 211 is a smooth arc surface, which plays a role in quick positioning and guidance when entering the insertion hole 112. When the locking end 212 begins to enter the insertion hole 112, further pushing into the insertion hole 112 will generate significant resistance. The interference fit between the locking end 212 and the insertion hole 112 causes partial elastic deformation of the locking end 212 until the locking end 212 is fully inserted into the insertion hole 112. In this way, while ensuring a firm connection between the corner bracket 2 and the edge strip 1, faster assembly efficiency can be achieved.

[0066] In this embodiment, the locking end 212 is provided with an elastic area 2121 and a clearance area 2122. By combining the elastic area 2121 and the clearance area 2122, the tightness of the locking end 212 can be effectively set, which facilitates the judgment of the insertion status of the locking end 212 during the assembly process.

[0067] In other embodiments, the diffuser plate 3 is a flexible plastic part with a plate-like structure. The surface of the diffuser plate 3 has a corrugated structure, and its thickness is less than 0.8 mm. Currently, commonly used diffuser plates 3 are plastic sheets with a thickness of 0.8 mm or more. When the area of ​​the diffuser plate 3 increases, the thickness of the diffuser plate 3 needs to be less than 0.8 mm to reduce the stress on the fixed connection between the diffuser plate 3 and the edge strip 1. Due to the reduction in thickness, the "flexibility" of the diffuser plate 3 becomes more apparent. When the thickness is reduced to a certain extent, the diffuser plate 3 can be made as a thin film. Producing and fixing it to the edge strip 1 as a thin film is more conducive to reducing the sagging of the diffuser plate 3. The corrugated structure on the surface of the diffuser plate 3 can effectively disperse the emitted light, further increasing the area of ​​light emission, while making the light softer and more comfortable.

[0068] In this embodiment, to meet existing process requirements, the edge strip 1 is an injection-molded part, and the corner bracket 2 is a rigid plastic part or a metal part. The plastic edge strip 1 is obtained by hot melt extrusion molding, and then cut into shape according to length and angle by a cutting device. The corner bracket 2 is made of rigid plastic or metal, which more easily meets the structural requirement of bearing a certain supporting force between two adjacent edge strips 1.

[0069] In summary, the frame structure provided in this embodiment uses a connecting structure to fix the diffuser plate and edge strips together to form an integrated structure, achieving a tight connection between the edge strips. Simultaneously, the connecting structure ensures stable and uniform stress on the connection between the edge strips and the diffuser plate, and the sag of the diffuser plate is controllable and reduced. Furthermore, the choice of diffuser plate thickness is contrary to existing technologies; the larger the diffuser plate area, the thinner the thickness is required, reducing the stress on the diffuser plate from the connecting structure and significantly minimizing the sag caused by gravity deformation.

[0070] Secondly, the edge strips and corner brackets can be standardized in molding and assembly. As the area of ​​the diffuser plate increases, its thickness needs to be reduced. The fixed connection between the edge strips and the diffuser plate, forming an integrated structure, can be completed during the panel light production stage. While significantly reducing sag, the face frame structure offers higher production efficiency and lower cost compared to existing technologies, making it easier to promote and use.

[0071] Example 2

[0072] exist Figures 1-7 Based on the above Figures 8-10 This embodiment provides a panel light 200, including a light body 5, a light-emitting component 6, and the face frame structure 100 in Embodiment 1.

[0073] The lamp body 5 has a light-emitting cavity 51 and an edge 52 surrounding the end of the light-emitting cavity 51. The light-emitting component 6 is fixedly installed inside the light-emitting cavity 51, and the light-emitting cavity 51 faces the light-emitting area 4. In this embodiment, the light-emitting component 6 with LED beads 61 is fixedly installed on the top of the light-emitting cavity 51. The light emitted by the LED beads 61 is directed through the light-emitting cavity 51 onto the diffuser plate 3 of the light-emitting area 4, and after being processed by the diffuser plate 3, the light is emitted from the other side of the diffuser plate 3. In order to fix the face frame structure 100 to the lamp body 5, the base 11 has a top surface 113, which is located on the side opposite to the bottom 111 of the base 11, and the edge 52 is fixed to the top surface 113.

[0074] Furthermore, the lamp body 5 also includes a pressing part 53, which is disposed on the side of the edge 52 facing the light-emitting cavity 51. When the edge 52 abuts against and is fixed to the top surface 113, the pressing part 53 presses against the diffuser plate 3. Figure 10As shown, the top pressing part 53 has a U-shaped structure and exhibits a certain degree of elastic deformation when pressing the diffuser plate 3. The top pressing part 53 can effectively distribute the stress at the welding position between the edge strip 1 and the diffuser plate 3, avoiding the possibility of the diffuser plate 3 falling off and sagging after the connection structure 121 ages during long-term use, thus improving the service life of the panel light 200.

[0075] In some embodiments, the panel light 200 further includes a fastener 7, and the base 11 is also provided with a slot 114, which is disposed between the insertion hole 112 and the support portion 12. The fastener 7 passes through the edge 52 and is locked and fixed in the slot 114. The slot 114, the insertion hole 112, and the support portion 12 are integrally formed. A stepped groove 1141 is provided in the slot 114. In this embodiment, the fastener 7 is a screw. After passing through the edge 52, the thread of the fastener 7 continues to screw into the slot 114, and the thread teeth abut against the stepped groove 1141 to provide a locking force for the fastener 7. In practical applications, the width of the slot 114 should be smaller than the nominal diameter of the thread teeth of the fastener 7, and it should have a certain inclination, or be funnel-shaped to improve the locking force.

[0076] In summary, the panel light provided in this embodiment adopts the face frame structure of Embodiment 1. During installation, there is no need to adjust the fixing of the diffuser plate; only the face frame structure and the panel light need to be locked and fixed, significantly reducing installation time. Furthermore, because the diffuser plate is integrally fixed to the edge strip, the diffuser plate does not gradually shift or sag due to aging, thus improving the service life of the panel light.

[0077] Example 3

[0078] exist Figures 1-10 Based on the above Figure 11 This embodiment provides a panel light 200, similar to the panel light 200 described in Embodiment 2. However, the difference is that the panel light 200 in this embodiment has a hanging hook edge 13 on the base 11 of the edge strip 1. The hanging hook edge 13 is formed by extending from the side of the base 11 away from the bottom surface 111 in a direction away from the base 11. In this embodiment, the hanging hook edge 13 is located on the side away from the support portion 12.

[0079] During installation, in this embodiment, the panel light 200 can first be assembled by assembling the light body 5, the light-emitting component 6 and the face frame structure 100, and then the entire panel light 200 can be lifted up, the hanging hook edge 13 aligned and pushed into the pre-installed fixed light bracket (not labeled) on the ceiling, so as to realize the quick installation of the panel light 200.

[0080] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
