Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a pressure-edge type diffuser plate mounting structure and panel light. Background Technology

[0002] Panel lights are a common lighting device widely used in various locations to meet diverse lighting needs. Panel lights feature a diffuser plate that redistributes the light emitted by the light source, ensuring uniform scattering in all directions. However, commercially available panel lights often have a separate chassis and frame structure. During manufacturing, multiple screws are needed to mechanically secure the chassis and frame. This assembly structure not only leads to instability and deformation of the chassis and frame but also increases production costs due to the large number of screws required. Secondly, while the connecting plate of the frame has mounting slots, these slots are typically thin and have low structural strength, making them prone to deformation when the panel light housing is connected to its mounting parts. Furthermore, the diffuser plate is usually attached to the panel light housing with screws or adhesive, resulting in complex assembly and hindering production. Utility Model Content

[0003] The purpose of this utility model is to provide a pressure-edge type diffuser plate mounting structure and panel light, which can not only avoid the deformation of the panel light housing, but also reduce the cost and increase the structural strength; it can also make the assembly of the panel light housing and the diffuser plate more convenient and quick.

[0004] To achieve the above objectives, the technical solution adopted by this utility model in one aspect is as follows:

[0005] A pressure-edge type diffuser mounting structure for a panel light includes a chassis, a frame, and a diffuser plate. The chassis and the frame are integrally formed. The chassis has a recessed cavity, and the frame has outwardly folded straight edges around its perimeter. The outer side of the straight edges has an inwardly recessed mounting groove. The straight edges have a double-layer folded edge structure and include an inner folded edge and an outer folded edge connected to each other. The inner folded edge is closer to the chassis. The diffuser plate is disposed on the frame and covers the recessed cavity. The outer folded edge protrudes from the frame, and the end of the outer folded edge away from the inner folded edge has a pressure edge that bends toward the diffuser plate. The pressure edge abuts against the outer side of the diffuser plate and extends toward the chassis. The width of the pressure edge is less than or equal to the width of the frame.

[0006] As a preferred embodiment of this utility model, the pressing edge is a double-layer folded edge structure and includes an inner pressing edge and an outer pressing edge that are connected to each other, with the inner pressing edge being closer to the diffuser plate.

[0007] As a preferred embodiment of this utility model, a rib is provided at the connection between the chassis and the frame, and the rib abuts against the diffuser plate, causing the middle position of the diffuser plate to bulge outwards from the side away from the chassis.

[0008] As a preferred embodiment of this utility model, the mounting slot is a double groove mating structure, which includes a first groove and a second groove. The first groove is disposed on the outer folded edge and protrudes towards the inner folded edge, and the second groove is disposed on the inner folded edge and protrudes towards the chassis. The first groove is matched and engaged in the second groove, and the opening of the first groove is the opening of the mounting slot.

[0009] As a preferred embodiment of this utility model, notches are provided at the four corners of the straight edge.

[0010] As a preferred embodiment of this utility model, the chassis is provided with multiple transverse reinforcing ribs and multiple longitudinal reinforcing ribs.

[0011] In addition, to achieve the above objectives, the present invention adopts the following technical solution in another aspect:

[0012] A panel light includes a light source assembly and the edge-pressed panel light diffuser mounting structure described above, wherein the light source assembly is mounted in the recessed cavity.

[0013] The advantages of implementing the edge-pressed panel light diffuser mounting structure and panel light provided by this utility model compared with the prior art are as follows:

[0014] (1) The chassis and frame are integrally formed. Compared with the existing assembly method of connecting the chassis to the frame with screws, the deformation of the panel light housing can be avoided, and the cost is lower.

[0015] (2) The frame is provided with straight edges formed by outward folding around the perimeter. The straight edges are double-folded edge structures. This design can increase the structural strength of the straight edges, thereby increasing the structural strength of the mounting slot. This makes the connection between the mounting slot and its fixed part more stable and can prevent the mounting slot from deforming.

[0016] (3) The diffuser plate is set on the frame and covers the cavity. The outer folded edge protrudes from the frame. The end of the outer folded edge away from the inner folded edge is provided with a pressing edge that bends toward the diffuser plate. The pressing edge abuts against the outer side of the diffuser plate, which makes the assembly of the panel lamp housing and the diffuser plate more convenient and quick, and more conducive to production. At the same time, the pressing edge extends toward the chassis side, which can increase the contact area between the pressing edge and the diffuser plate, thereby improving the stability of the diffuser plate connected to the panel lamp housing.

Therefore, they should not be construed as limitations on this utility model. It should also be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

[0025] Please see Figures 1 to 3This utility model provides a preferred embodiment of a pressure-edge type panel light diffuser mounting structure, comprising a base 100, a frame 200, and a diffuser plate 300. The base 100 and the frame 200 are integrally formed. The base 100 has a cavity 101, and the frame 200 has outwardly folded straight edges 210 around its perimeter. The outer surface of the straight edges 210 has inwardly recessed mounting grooves 220. The straight edges 210 have a double-layer folded edge structure and include an inner folded edge 211 and an outer folded edge 211 that are connected to each other. 12. The inner folded edge 211 is close to the side of the chassis 100; the diffuser plate 300 is disposed on the frame 200 and covers the cavity 101; the outer folded edge 212 protrudes from the frame 200; the end of the outer folded edge 212 away from the inner folded edge 211 is provided with a pressing edge 230 bent toward the side of the diffuser plate 300; the pressing edge 230 abuts against the outer side of the diffuser plate 300 and extends toward the side of the chassis 100; the width of the pressing edge 230 is less than or equal to the width of the frame 200.

[0026] According to the edge-pressed panel light diffuser mounting structure of this utility model, firstly, the base 100 and the frame 200 are integrally formed. Compared with the existing assembly method of connecting the base 100 to the frame 200 with screws, this avoids deformation of the panel light housing and reduces costs. Secondly, the frame 200 has outwardly folded straight edges 210 around its perimeter. The straight edges 210 have a double-layer folded edge structure. This design increases the structural strength of the straight edges 210, thereby increasing the structural strength of the mounting slot 220. This makes the connection between the mounting slot 220 and its fixing part more stable and avoids... The mounting slot 220 is deformed; in addition, the diffuser plate 300 is set on the frame 200 and covers the cavity 101. The outer folded edge 212 protrudes from the frame 200. The end of the outer folded edge 212 away from the inner folded edge 211 is provided with a pressing edge 230 bent towards the diffuser plate 300. The pressing edge 230 abuts against the outer side of the diffuser plate 300, which makes the assembly of the panel light housing and the diffuser plate 300 more convenient and quick, and more conducive to production. At the same time, the pressing edge 230 extends towards the chassis 100, which can increase the contact area between the pressing edge 230 and the diffuser plate 300, thereby improving the stability of the diffuser plate 300 connected to the panel light housing.

[0027] For example, to increase the structural strength of the pressing edge 230, the pressing edge 230 is a double-layer folded edge structure and includes an inner pressing edge 231 and an outer pressing edge 232 that are connected to each other. The inner pressing edge 231 is close to the side of the diffuser plate 300.

[0028] For example, a raised rib 400 is provided at the connection between the chassis 100 and the frame 200. The raised rib 400 abuts against the diffuser plate 300, causing the middle position of the diffuser plate 300 to bulge outwards away from the chassis 100. With this design, when the pressing edge 230 abuts against the diffuser plate 300, the raised rib 400 abuts against the outer surface of the diffuser plate 300. The raised rib 400 contacts the surface of the diffuser plate 300, forming a lever fulcrum. The pressing edge 230 applies a vertically upward constraint force to the diffuser plate 300, and the center position of the diffuser plate 300 is subjected to a downward force due to the lever effect, causing the middle position of the diffuser plate 300 to bulge outwards away from the chassis 100. This prevents the diffuser plate 300 from being recessed towards the chassis 100, thus preventing light spots from appearing on the panel light and improving the uniformity of the light fixture's brightness.

[0029] For example, the mounting slot 220 is a double-groove mating structure, which includes a first groove 221 and a second groove 222. The first groove 221 is disposed on the outer folded edge 212 and protrudes towards the inner folded edge 211. The second groove 222 is disposed on the inner folded edge 211 and protrudes towards the chassis 100. The first groove 221 is fitted into the second groove 222, and the opening of the first groove 221 is the opening of the mounting slot 220. This design makes the connection between the outer folded edge 212 and the inner folded edge 211 more stable, thereby further increasing the structural strength of the mounting slot 220 and preventing deformation of the mounting slot 220 when the panel light housing is installed and applied.

[0030] For example, notches 240 are provided at all four corners of the straight edge 210. This design facilitates the embedded installation of the panel light housing with the keel structure and the dimensional positioning of the mounting surface.

[0031] For example, to further enhance the structural strength of the chassis 100, multiple transverse reinforcing ribs 102 and multiple longitudinal reinforcing ribs 103 are evenly distributed on the chassis 100.

[0032] In addition, this utility model also provides a panel light, which includes a light source assembly and the edge-pressed panel light diffuser mounting structure described in the above-mentioned items, wherein the light source assembly is installed in the cavity 101. It should be noted that since the panel light uses the edge-pressed panel light diffuser mounting structure described in the above-mentioned items, it has the same technical effect as the edge-pressed panel light diffuser mounting structure, and will not be described again here.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
