[0029] The utility model will be described in detail below in combination with Figures 1-6 .

[0030] A frameless and screwless panel light includes a base 10 with an opening 101. A light-emitting device 20 is disposed within the opening 101 of the base 10. The base 10 also has a power supply device electrically connected to the light-emitting device 20. At least two sides of the base 10 are provided with first locking portions 102 extending in the opposite direction to the opening 101. The light-emitting device 20 is located in the light-emitting direction of the light-emitting device 20. The four sides of the diffuser 30 are provided with outer edges 301 extending in the opposite direction to the opening 101. The outer edges 301 are located on the outside of the base 10, and each outer edge 301 has a second locking portion 302 adapted to the first locking portion 102. The diffuser 30 is fixed by the cooperation of the first locking portion 102 and the second locking portion 302, eliminating the need for a separate frame and screw assembly, reducing production costs, simplifying the structure, and improving the product's aesthetics. The outer edges 301 also serve as a limit to prevent the base 10 from sliding out radially and separating from the diffuser 30.

[0031] Specifically, such as Figures 4-6 As shown, the chassis 10 has an upward opening 101. At least two sides of the chassis 10 are provided with a first engaging portion 102 extending downward. The number of "at least two sides" includes various cases, such as any two adjacent sides, any two opposite sides, any three sides, or all four sides. Since the four sides of the diffuser plate 30 are also provided with an outer edge 301 extending downward, the outer edge 301 plays a certain limiting role. Therefore, even if the chassis 10 is provided with the first engaging portion 102 on only two sides, there is no need to worry about the chassis 10 sliding out radially and separating from the diffuser plate 30, because the edge of the chassis 10 without the first engaging portion 102 will be abutted by its corresponding outer edge 301. The number of first engaging portions 102 and second engaging portions 302 is the same. A power supply box (not shown in the figure) is provided on the side of the chassis 10. A power supply device is installed in the power supply box. Since the power supply device is very common in the art, it will not be described in detail here. Please refer to the prior art for details.

[0032] The diffuser and chassis 10 are made of materials with a certain degree of elasticity, such as rigid plastics. Figures 4-6 As shown, the first snap-fit ​​part 102 is snapped into the second snap-fit ​​part 302 above it by elastic deformation. After being snapped in, the first snap-fit ​​part 102 cannot fall out due to the presence of the second snap-fit ​​part 302, thereby achieving the snap-fit ​​fixation between the diffuser plate 30 and the chassis 10. The diffuser cover is made by flat blow molding process, and the chassis 10 is made by metal stamping or plastic vacuum forming process.

[0033] In this embodiment, a first snap-fit ​​portion 102 is provided on each of the four sides of the chassis 10. Specifically, this arrangement enhances the stability of the connection between the diffuser plate 30 and the chassis 10, and there is a gap 103 between each first snap-fit ​​portion 102, which facilitates snap-fit.

[0034] In the embodiment, the first clamping portions 102 are spaced apart from each other by a spacing 103. Specifically, the first clamping portions 102 are not integrally arranged in a circle, but are discontinuously arranged, which facilitates clamping.

[0035] In the embodiment, the inner side of the outer side 301 is provided with an inner side 104, and the first clamping portion 102 is arranged on the inner side of the inner side 104. Specifically, compared with the case where the first clamping portion 102 is arranged on the outer side of the inner side 104, the clamping position between the diffuser plate 30 and the chassis 10 can be hidden, and the clamping trace cannot be seen from the front of the panel lamp, which further improves the appearance of the product. The inner side 104 and the outer side 301 can be provided with anti-skid stripes or convex points to increase the friction, or can be provided with an adhesive layer, which further increases the connection strength between the chassis 10 and the diffuser plate 30.

[0036] In the embodiment, the first clamping portion 102 is a circular arc roll edge, which avoids scratching the user. Further, the second clamping portion 302 is a circular arc protrusion protruding from the outer side 301 to the inner side thereof, and the circular arc protrusion and the circular arc roll edge are in concave-convex cooperation. The circular arc of the circular arc protrusion and the circular arc roll edge can also reduce the resistance during clamping, which facilitates clamping.

[0037] In the embodiment, the diffuser plate 30 includes a micro-convex substrate 303 arranged in the light emitting direction of the light emitting device 20 and an outer side 301 connected to the periphery of the micro-convex substrate 303, and the micro-convex substrate 303 protrudes away from the chassis 10. Specifically, this can reduce the height of the whole lamp and make the light more uniform.

[0038] In the embodiment, the light emitting device 20 includes a plurality of rows of lamp beads, and each row of lamp beads is arranged side by side and electrically connected to the power supply device.

[0039] In the embodiment, each row of lamp beads includes a lamp plate 201 mounted on the chassis 10 and a plurality of lamp bead bodies 202 mounted on the lamp plate 201, each lamp bead body 202 is electrically connected to the lamp plate 201, and the lamp plate 201 is electrically connected to the power supply device. Specifically, each lamp bead body 202 can be an LED, which has the advantages of high light intensity, low power consumption, and low cost; the lamp plate 201 is a light source plate; since the light emitting device 20 is very common in the art, it will not be described here, and reference can be made to the prior art.

[0040] In the embodiment, the light emitting device 20 further comprises a lens arranged on each lamp bead body 202. Specifically, the light is controlled and adjusted by the lens to achieve a specific lighting effect. The specific lens has the following effects: first, it improves the utilization rate of light, effectively focuses or scatters the light emitted by the lamp bead, so that more light can be utilized, reduces the waste of light, and improves the overall light efficiency of the lamp; second, it improves the light quality, filters out part of the stray light, makes the light more pure, improves the purity and quality of the light, avoids the occurrence of glare and other adverse phenomena, and provides users with a more comfortable lighting experience; third, it controls the directionality of light, the lens can change the emission angle of light, so that the light is more concentrated or uniformly distributed to meet the lighting needs of different scenes and purposes, such as a spotlight needs to focus light on a specific area, while a scattering lamp needs to evenly scatter light in a larger range. The structure, principle and specific setting position of the lens can refer to the existing technology in the art.

[0041] In the embodiment, the chassis 10 further comprises a flexible circuit board (not shown in the figure), i.e. FPC, and the plurality of lamp boards 201 are electrically connected with the flexible circuit board. The flexible circuit board is the existing technology in the art, which will not be described here.

[0042] In the embodiment, the side of the chassis 10 is provided with a plurality of shockproof hooks (not shown in the figure). Specifically, the number of shockproof hooks is two on each of the opposite sides, and can be more or less. The shockproof hooks facilitate the assembly of the chassis 10 on the ceiling or other similar positions, and can play a certain shockproof role for the whole. The shockproof hook is the existing technology in the art, which will not be described here.

[0043] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
