The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0036] Reference is made below Figures 1-12 The lighting device 100 according to the embodiments of the present application is described.

[0037] As Figures 1-2 shown, the lighting device 100 according to the embodiments of the present application comprises a lampshade 10 and a panel 12 and a sealing member 13, the lampshade 10 is formed with a containing cavity 101 with an open side in a first direction, the open side of the lampshade 10 is formed with a first mounting groove 113 extending in a ring shape along the circumference of the containing cavity 101; the circumference of the panel 12 is fitted in the first mounting groove 113 to cover the opening, the panel 12 is a light-transmitting plate, the two side surfaces in the thickness direction of the light-transmitting plate are respectively formed into a diffusion surface 121 and an anti-glare surface 122, the diffusion surface 121 is the side surface of the light-transmitting plate facing the base plate 20, and the anti-glare surface 122 is the side surface of the light-transmitting plate away from the base plate 20; the sealing member 13 is arranged in the first mounting groove 113 to seal the gap between the panel 12 and the inner wall of the first mounting groove 113.

[0038] Specifically, the containing cavity 101 is mainly used for containing the lighting component 30 such as a bulb and electrical elements; the panel 12 is connected with the lampshade 10 to cover the opening of the lampshade 10, so that the lighting device 100 forms a relatively closed space, thereby the containing cavity 101 can be isolated from the external environment, and the risk of accidental touching of the high-temperature bulb by the user during use of the lighting device 100 can be reduced; at the same time, the sealing member 13 can seal the connection position of the panel 12 and the lampshade 10, thereby further preventing dust, impurities, mosquitoes and the like from entering the containing cavity 101 from the connection between the panel 12 and the lampshade 10 to damage the structure inside the containing cavity 101 of the lighting device 100, thereby improving the service life of the lighting device 100, and at the same time, it can also prevent impurities from entering the containing cavity 101 and accumulating in the containing cavity 101 to affect the lighting efficiency, thereby improving the lighting effect of the lighting device 100.

[0039] It should be noted that the lighting device 100 mainly scatters light outward through the panel 12, and thus the panel 12 is a transparent plate, which can ensure the lighting effect of the lighting device 100.

[0040] In addition, the two side surfaces of the light-transmitting plate in the thickness direction are formed into a diffusion surface 121 and an anti-glare surface 122 respectively, the diffusion surface 121 is the side surface of the light-transmitting plate facing the base plate 20, and the anti-glare surface 122 is the side surface of the light-transmitting plate away from the base plate 20. It can be understood that the panel 12 has both diffusion effect and anti-glare effect, which can reduce the need for additional optical elements, thereby reducing the design difficulty and assembly steps of the lighting device 100, thereby reducing the production cost of the lighting device 100. In addition, it can also be understood that the anti-glare surface 122 is arranged towards the user side, wherein the diffusion surface 121 is mainly used to disperse the light of the light source, thereby making the light out of the light-transmitting plate more uniform; the anti-glare surface 122 is mainly used to reduce reflection and glare, thereby protecting the eyes of the user from strong light interference; thus, the anti-glare surface 122 is arranged towards the user, and the diffusion surface 121 is arranged on the side of the light-transmitting plate away from the anti-glare surface 122. Not only does the lighting device 100 have good lighting effect, but also unnecessary reflection and glare can be reduced, thereby improving the anti-glare effect of the lighting device 100 and improving the user experience.

[0041] According to the lighting device 100 of the embodiment of the present application, by arranging the first mounting groove 113 and the sealing element 13, the lighting device 100 can be waterproof, dustproof and moisture-proof, thereby ensuring the lighting effect of the lighting device 100, and at the same time, the connection arrangement of the panel 12 and the lampshade 10 can be simplified, thereby the assembly steps of the lighting device 100 can be simplified, and thereby the production cost of the lighting device 100 can be reduced; by arranging the panel 12 as a transparent plate and the transparent plate having the diffusion surface 121 and the anti-glare surface 122, the lighting device 100 can have good lighting effect, and at the same time, the need for additional optical elements can be reduced, thereby the design difficulty and assembly steps of the lighting device 100 can be reduced, and thereby the production cost of the lighting device 100 can be reduced; in addition, unnecessary reflection and glare can be reduced, thereby the anti-glare effect of the lighting device 100 can be improved, and the user experience can be improved.

[0042] According to some embodiments of the present application, as shown in Figure 4 It can be understood that the sealing element 13 is made of elastic material, so that the panel 12 is elastically sealed between the sealing element 13 and the first mounting groove 113, wherein the elastic sealing has high sealing performance and is easier to assemble, so that the sealing element 13 elastically abuts between the panel 12 and the side wall of the first mounting groove 113, which can further improve the sealing effect between the panel 12 and the frame 11, and at the same time, the assembly of the panel 12 and the frame 11 can be more convenient.

[0043] Optionally, the sealing member 13 can extend annularly around the circumference of the frame 11, so that the mounting rate of the lampshade 10 can be improved, and the mounting rate of the lighting device 100 can be improved, in addition, the sealing member 13 can also be formed into a strip shape, and the number of the sealing member 13 is multiple, so that when one of the sealing members 13 is damaged, only the damaged part can be replaced, and the maintenance cost of the lighting device 100 can be reduced.

[0044] According to some embodiments of the present application, as shown in Figure 4 The side wall of the first mounting groove 113 is formed with a limiting groove, and the sealing member 13 is fitted in the limiting groove. It can be understood that the limiting groove has a limiting positioning effect on the sealing member 13, which can limit the movement of the sealing member 13 in the first mounting groove 113, and thus prevent the sealing member 13 from being pulled out of the first mounting groove 113, thereby ensuring the sealing property of the lampshade 10.

[0045] According to some embodiments of the present application, as shown in Figure 4 The cross section of the sealing member 13 perpendicular to the circumference of the lampshade 10 is U-shaped, and the open end of the sealing member 13 faces a second direction perpendicular to the first direction. It can be understood that the opening direction of the sealing member 13 is perpendicular to the mounting direction of the panel 12, so that on the one hand, the contact area of the sealing member 13 with the panel 12 and the panel 12 can be increased, thereby improving the sealing property of the connection between the panel 12 and the panel 12, and thus improving the mosquito-proof and dust-proof effect of the lighting device 100; on the other hand, the U-shaped sealing member 13 has a large deformation space, which is conducive to the installation and disassembly of the panel 12; at the same time, the sealing member 13 also has a certain elasticity, so that when the panel 12 is installed to the mounting position, the sealing member 13 will generate an opposite force on the panel 12 due to elastic reset, so that the panel 12 can be more closely attached to the frame 11, thereby further improving the sealing property of the connection between the panel 12 and the panel 12, and thus further improving the mosquito-proof and dust-proof effect of the lighting device 100.

[0046] According to some embodiments of the present application, as shown in Figure 2 and Figure 4As shown, the lampshade 10 comprises: a frame 11 and a bottom plate 20, the frame 11 is annular; the bottom plate 20 is arranged on one side of the frame 11 in the first direction and connected with the frame 11 to jointly form a containing cavity 101. It can be understood that the panel 12 and the bottom plate 20 are arranged on both sides of the frame 11 in the first direction respectively, and are used for covering the openings of the frame 11 in the first direction respectively. Specifically, the frame 11 mainly provides mounting space for the panel 12 and the bottom plate 20; the bottom plate 20 is mainly used for mounting and fixing the electrical elements and the lighting assembly 30 of the lighting device 100, and provides a stable support platform for the electrical elements and the lighting assembly 30; in addition, the bottom plate 20 usually contains a circuit design inside, which is used for connecting the power supply and various electrical elements of the lamp, ensuring that the current is safely transmitted to the bulb, thereby realizing the normal work of the lighting device 100.

[0047] It should be noted that the bottom plate 20, the panel 12 and the frame 11 are connected to form a relatively closed space of the lighting device 100, so that dust, insects and other impurities can be prevented from entering the containing cavity 101, thereby improving the cleanliness of the lighting device 100, and improving the lighting effect and service life of the lighting device 100.

[0048] According to some embodiments of the present application, the frame 11 is formed with a positioning groove 111 at one end thereof in the first direction away from the first mounting groove 113, the positioning groove 111 extends in the circumferential direction of the frame to be annular, and the bottom plate 20 has an extension edge 21 extending towards one side of the panel 12 in the circumferential direction, and the extension edge 21 is fitted in the positioning groove 111.

[0049] It can be understood that the positioning groove 111 cooperates with the extension edge 21 to limit the position of the bottom plate 20, thereby facilitating the assembly of the bottom plate 20 and the lampshade 10 and improving the assembly accuracy of the bottom plate 20 and the lampshade 10. It should be noted that when the bottom plate 20 and the lampshade 10 are fixed, the extension edge 21 can be fitted in the positioning groove 111 first to preliminarily fix the bottom plate 20, initially align and fix the bottom plate 20 and the lampshade 10, and prevent them from being displaced in the subsequent steps, and then the bottom plate 20 and the lampshade 10 are finally fixed.

[0050] According to some embodiments of the present application, as Figure 4As shown, the periphery of the chassis 20 is bent in the first direction towards the frame 11 to form an extension edge 21, and the positioning groove 111 is formed in the periphery of the opening. In this way, the matching difficulty of the extension edge 21 and the positioning groove 111 can be simplified, so that the extension edge 21 can be more easily matched into the positioning groove 111, thereby the assembly rate of the chassis 20 and the frame 11 can be improved; at the same time, the periphery of the chassis 20 is bent in the first direction towards the frame 11 to form the extension edge 21, wherein the bending operation is relatively simple, thereby the production difficulty of the chassis 20 can be reduced.

[0051] According to some embodiments of the present application, as shown in Figure 4 As shown, the frame 11 has a first mounting hole 112, the first mounting hole 112 is arranged on the side of the positioning groove 111 facing the opening, and the chassis 20 has a second mounting hole, the chassis 20 is fastened and connected with the lampshade 10 by being threaded through the first mounting hole 112 and the first mounting hole 112. It can be understood that the lampshade 10 and the chassis 20 are fastened and connected, that is, the lampshade 10 and the chassis 20 are detachably connected, which can increase the convenience of mounting and dismounting the lighting device 100, thereby improving the convenience of mounting, dismounting and repairing the lighting device 100.

[0053] According to some embodiments of the present application, as shown in Figures 3-4 As shown, the first mounting hole 112 extends along the periphery of the opening to form an annular groove. In this way, the manufacturing steps of the lampshade 10 can be simplified, thereby the production cost of the lampshade 10 can be reduced, so that the production cost of the entire lighting device 100 can be reduced, and the production efficiency of the lighting device 100 can be improved.

[0054] According to some embodiments of the present application, as shown in Figures 5-12 As shown, the anti-glare surface 122 has a transparent microcrystalline structure, and the microcrystalline structure is a polygonal protrusion or recess towards the diffusion surface 121. The protrusion structure helps to disperse the incident light in different directions, thereby reducing direct reflection, so that the influence of glare on the eyes can be reduced; the recess structure changes the light path, so that the light is refracted and reflected multiple times when entering the material, thereby further enhancing the diffusion effect of the light; therefore, the transparent microcrystalline structure formed on the anti-glare surface 122 can effectively disperse the incident light while ensuring the light transmittance, thereby reducing direct reflection and making the emitted light more dispersed and soft, thereby achieving the anti-glare effect.

[0055] Optionally, the polygon can be a quadrilateral or a hexagon, which can effectively scatter light. It should be noted that the design of the polygon can be adjusted according to specific needs to achieve the best anti-glare effect.

In addition, it can also be understood that the outer circumferential surface of the rectangular frame of the present application is an arc surface, which can improve the appearance of the frame 11, thereby improving the appearance of the entire device.
