[0036] It should be noted that, for the detachable installation of the lens assembly on the lamp holder 100, the lens assembly can be detachably connected to the lamp holder 100 at positions on opposite sides of the lens assembly, or can be detachably connected at one side and the other side has a mutual abutting mode of interaction, so that the lens assembly can be integrally disassembled and installed, and can also be stably connected to the lamp holder 100 after installation; for the lens assembly connected to the lamp holder 100 by rotating, one side of the lens assembly is rotatably connected to the lamp holder 100, and the lens assembly is presented as a flip type covering the light emitting side in the light source 400, and the other side is connected to the lamp holder 100 by a detachable connection mode; for the lens assembly connected to the lamp holder 100 by rotating and detachable combination, the lens assembly not only presents as a flip type covering the light emitting side in the light source 400, but also can be integrally disassembled and installed, that is, the lens assembly is detachably connected to the lamp holder 100, and one side is rotatably connected to the lamp holder 100.

[0037] Without loss of generality, the lens assembly can be a single component, taking the lens 300 as the main body, and connecting structure is provided on the lens 300, and then the connecting structure is connected to the lamp holder 100 by rotating and / or detachable connection, so that the lens 300 can be disassembled and replaced; or the lens assembly can be multiple components, the lens 300 is connected to the lamp holder 100 by an auxiliary component, the auxiliary component can be rotatably and / or detachably connected to the lamp holder 100, so that the lens 300 can be disassembled and replaced after the auxiliary component is rotated or disconnected from the lamp holder 100. In addition, the lens assembly is arranged on the light emitting side of the light source 400, and generally, the light emitting side of the lamp is the side that is less hindered and exposed, thereby providing sufficient operation space for the user when replacing the lens 300, reducing the hindrance of irrelevant components, and improving the operation convenience of replacing the lens 300.

[0038] In an embodiment, please refer to Figure 2 , Figure 3 and Figure 5The lens assembly further comprises a pressing cover 200 abutting the periphery of the lens 300 and rotatably and / or detachably connected to the lamp holder 100. It can be understood that the user does not need to use complex tools or perform tedious operations, but only needs to rotate or detach the pressing cover 200 to contact the restriction of the lens 300, so as to easily complete the disassembly and assembly of the lens 300; at the same time, when disassembling and assembling the lens 300, it avoids directly applying excessive force to the lens 300 or the lamp holder 100, reducing the risk of damage to the lens 300 or the lamp holder 100. Moreover, the pressing cover 200 can also prevent impurities from entering the inside of the lamp, keeping the lamp clean and functional. In addition, the user does not need to directly touch the high-temperature light source 400, the lens 300 or the sharp edge of the lamp holder 100, thereby avoiding the safety hazards of burns or cuts. Of course, in other embodiments, a connecting structure can also be provided on the lens 300 to realize rotatable and / or detachable connection with the lamp holder 100.

[0039] Further, in the present embodiment, please refer to Figure 2 、 Figure 4 and Figure 5 The first side 201 of the pressing cover 200 is rotatably connected to the lamp holder 100, and the second side 202 opposite to the first side 201 is detachably connected to the lamp holder 100. It can be understood that the first side 201 of the pressing cover 200 is designed to be rotatably connected, so that the user can easily fix or release the lens 300 by rotating the pressing cover 200 when disassembling and assembling the lens 300, avoiding the use of additional tools or complex operation steps, thereby simplifying the disassembly and assembly process and improving the work efficiency. At the same time, since the second side 202 of the pressing cover 200 is detachably connected, the user can choose to completely detach the pressing cover 200 for lens replacement, or only rotate the pressing cover 200 to loosen the lens 300 for maintenance, so as to meet the needs of different scenes in a flexible disassembly and assembly manner, improving the operation convenience of the user. In addition, the rotatable connection design makes the user not need to apply excessive force to the lens 300 or the lamp holder 100 when disassembling and assembling the lens 300, reducing the risk of damaging the lens 300 or the lamp holder 100. Of course, in other embodiments, the pressing cover 200 can be detachably connected to the lamp holder 100 at the first side 201 and the second side 202.

[0040] Specifically, in the embodiment, the first side 201 of the pressing cover 200 is provided with a shaft sleeve 220, the lamp holder 100 is provided with a rotating shaft 150 corresponding to the shaft sleeve 220, and the rotating shaft 150 is rotatably arranged in the shaft sleeve 220. It can be understood that the cooperation between the shaft sleeve 220 and the rotating shaft 150 helps to reduce the resistance torque during rotation, so that the pressing cover 200 can rotate around the rotating shaft 150 easily and smoothly, thereby improving the stability of rotation. At the same time, the close cooperation between the shaft sleeve 220 and the rotating shaft 150 can effectively limit the movement direction of the pressing cover 200, avoiding loosening or shaking of the pressing cover 200 during rotation due to external force or vibration. In addition, the structure of the shaft sleeve 220 relative to the rotating shaft 150 is relatively fragile, and the rotating shaft 150 is arranged in the lamp holder 100, which reduces the probability of damage to the lamp holder 100. Of course, in other embodiments, the rotating shaft 150 can also be arranged on the pressing cover 200, and the shaft sleeve 220 can be arranged at the corresponding position of the lamp holder 100.

[0041] Further, in the embodiment, please refer to Figure 3 and Figure 5 The shaft sleeve 220 is provided with a dismounting opening 221 parallel to the light emitting side of the light source 400, and the dismounting opening 221 penetrates the shaft sleeve 220 along the axial direction of the shaft sleeve 220. It should be noted that the dismounting opening 221 can be partially parallel to the light emitting side in the light source 400, or can be entirely parallel to the light emitting side of the light source 400, so that the rotating shaft 150 is hung on the shaft sleeve 220, not only ensuring the connection stability of the pressing cover 200 and the lamp holder 100, but also allowing the user to not only dismount the lens 300, but also dismount the pressing cover 200, ensuring that the specifications of the pressing cover 200 are adapted to the lens 300, and further ensuring the stability of the lens 300 on the lamp holder 100. At the same time, the dismounting opening 221 is arranged penetratingly along the axial direction of the shaft sleeve 220, so that the user can easily place the rotating shaft 150 on the shaft sleeve 220 from the dismounting opening 221 along the radial direction of the shaft sleeve 220, without the need for complex rotation or adjustment operations, thereby improving the operation convenience of the user in assembling the pressing cover 200. Of course, in other embodiments, the shaft sleeve 220 can also be a cylindrical structure, and the rotating shaft 150 is connected to the lamp holder 100 at one end. Then, the rotating shaft 150 can be axially inserted into the shaft sleeve 220 through the other open end.

[0042] In an embodiment, please refer to Figures 2 to 4The second side 202 is connected to the lamp holder 100 by a snap structure. It can be understood that the snap structure is usually designed to be simple and easy to operate, and the user only needs to realize the connection or disconnection by a simple pressing, rotating or sliding action, so that the disassembly process becomes very fast, saves time and improves work efficiency. At the same time, the design of the snap structure enables the user to complete the disassembly without using any tools, that is, the user does not need to carry an additional tool kit, but only needs to rely on both hands to complete the operation, further improving the convenience of disassembly. In addition, the snap structure usually has firm and reliable connection performance, but when disassembled, it will not cause excessive pressure or damage to the edge cover 200 and the lamp holder 100, thereby reducing the risk of damaging the lamp holder 100 or the second side 202 during disassembly, and protecting the integrity of the lamp. Of course, in other embodiments, the second side 202 can also be connected to the lamp holder 100 by clamping, inserting or screwing.

[0043] In an embodiment, referring to Figures 2 to 5 The lamp holder 100 is provided with a relief opening 140 corresponding to the snap structure, and the snap structure includes a buckle groove 230 and a buckle part 130. The buckle groove 230 is arranged on the second side 202 of the edge cover 200, and the buckle part 130 is arranged on the side of the lamp holder 100 away from the light source 400 and buckled to the buckle groove 230 through the relief opening 140. It can be understood that the design of the buckle groove 230 and the buckle part 130 makes the buckle operation intuitive and easy to understand, and the user only needs to align the buckle part 130 with the buckle groove 230 and complete the connection by a simple pressing or rotating action, thereby improving the convenience of operation. At the same time, the relief opening 140 provided on the lamp holder 100 provides sufficient space for the buckle part 130 to smoothly buckle into the buckle groove 230, so as to avoid the problem of buckle difficulty or disconnection due to insufficient space, thereby improving the smoothness of the buckle operation. In addition, the buckle part 130 is arranged on the side of the lamp holder 100 away from the light source 400, which not only guarantees the acting force between the buckle part 130 and the buckle groove 230, but also provides powerful support for operating the buckle part 130, so that it can withstand a certain tension and pressure, and ensure the stable connection between the lamp holder 100 and the second side 202. Of course, in other embodiments, the buckle part 130 can be arranged on the edge cover 200, and the buckle groove 230 can be arranged on the lamp holder 100, or the buckle part 130 of the lamp holder 100 is provided with a buckle hook, and the edge cover 200 is provided with a buckle rod corresponding to the buckle hook of the buckle part 130.

[0044] Specifically, in the present embodiment, referring to Figures 2 to 4, the buckle portion 130 is rotatably connected to the lamp holder 100, and the rotation axis is arranged adjacent to the periphery of the light source 400. When the end of the buckle portion 130 away from the rotation axis abuts against the side of the lamp holder 100 away from the light source 400, the locking shaft of the buckle portion 130 is buckled into the buckle groove 230. The buckle portion 130 is rotatably connected to the lamp holder 100, and the rotation axis is arranged adjacent to the periphery of the light source 400. Such design enables the buckle portion 130 to generate a larger torque when buckled. When the end of the buckle portion 130 away from the rotation axis abuts against the side of the lamp holder 100, the locking shaft can be firmly buckled into the buckle groove 230, forming a stable connection, thereby ensuring that the buckle portion 130 and the buckle groove 230 can remain stable under stress and are not easy to loosen or fall off. At the same time, the rotatable design of the buckle portion 130 enables the user to easily buckle or unlock the buckle portion 130 from the buckle groove 230, thereby improving the convenience of operation and enabling the user to quickly complete the installation or disassembly work. In addition, during the buckling process, the stress of the buckle portion 130 on the lamp holder 100 can be gradually dispersed to the lamp holder 100 and the edge cover 200 along the rotation process, avoiding stress concentration and reducing the risk of damage caused by excessive stress. Of course, in other embodiments, the buckle portion 130 can also be rotated towards the side of the lamp holder 100 where the light source 400 is arranged, so that when the buckle portion 130 is rotated to extend parallel to the light-emitting side of the light source 400, the locking shaft of the buckle portion 130 is stably buckled into the buckle groove 230.

[0045] In an embodiment, referring to Figure 2 and Figure 3 , the lamp holder 100 is provided with a light source groove 110, and the light source 400 is arranged in the light source groove 110. The periphery of the groove opening of the light source groove 110 is recessed with a sealing ring groove 120, and the sealing ring groove 120 is provided with a sealing ring 160. The sealing ring 160 is clamped between the sealing ring groove 120 and the lens 300. It can be understood that the sealing ring 160 is clamped between the sealing ring groove 120 and the lens 300, forming a tight waterproof barrier. When water tries to invade from the outside, the sealing ring 160 can effectively block the water, ensuring the dryness between the light source 400 and the lens 300. Similarly, the sealing ring 160 can also prevent dust and dirt from entering the light source groove 110, reducing the probability of damage to the light source 400 or the influence on the light-emitting effect of the light source 400. In addition, the sealing ring 160 can also avoid hard contact between the lens 300 and the lamp holder 100. When the buckle structure locks the edge cover 200 to the lamp holder 100, the sealing ring 160 can provide a buffer for the lens 300, thereby reducing the probability of damage to the lens 300. Of course, in other embodiments, a stepped structure can also be arranged between the periphery of the lens 300 and the groove opening of the light source groove 110 to increase the path of external substances entering the light source groove 110, thereby improving the sealing performance of the light source groove 110.

[0046] Further, in the present embodiment, referring toFigure 2 、 Figure 3 and Figure 5 The outer periphery of the pressing cover 200 is bent with a protective flange 210, the lens 300 is covered on the slot of the light source groove 110, the pressing cover 200 is covered on the periphery of the lens 300, and the protective flange 210 is circumferentially abutted at the joint between the lens 300 and the light source groove 110. It can be understood that the pressing cover 200 is continuous or discontinuous annular, the pressing cover 200 is covered on the periphery of the lens 300, and through close fitting, the gap between the lens 300 and the light source groove 110 is reduced, at the same time, the protective flange 210 is circumferentially abutted at the joint between the lens 300 and the light source groove 110, forming an additional sealing layer, effectively preventing external pollutants such as dust and moisture from entering the inside of the light source groove 110. In addition, the protective flange 210 not only enhances the connection strength between the pressing cover 200 and the light source groove 110 and the lens 300, but also improves the structural stability of the entire light source 400 assembly, which helps to resist external impact and vibration, and protects the light source 400 and the lens 300 from being damaged. Among them, the protective flange 210 can also block the light emitted by the light source 400 from leaking between the slot of the light source groove 110 and the lens 300, optimizing the light output effect of the light source 400. Of course, in other embodiments, the pressing cover 200 can also be pressed only on the side of the lens 300 away from the slot of the light source groove 110.

[0047] The above only describes the exemplary embodiments of the present application, and does not limit the patent scope of the present application, any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
