[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a lamp includes a lamp housing 200 and a light-transmitting cover plate 300.

[0031] The lamp housing 200 can serve as a mounting base for mounting the light-transmitting cover 300.

[0032] The lamp housing 200 can be a plate-like structure. In some embodiments, at least a portion of the lamp housing 200 can be a flat plate structure. In some embodiments, at least a portion of the lamp housing 200 can be a three-dimensional structure. In some embodiments, the lamp housing 200 can include various shapes, such as circular, rectangular, elliptical, etc., and its specific shape can be set according to actual needs.

[0033] In some embodiments, the lamp housing 200 can be made of various materials, such as metal, plastic, wood, etc. When metal is used, the lamp housing 200 can be used for heat dissipation. In some embodiments, the lamp housing 200 can be formed by various methods, such as at least one of machining, welding, stamping, casting, injection molding, etc.

[0034] In some embodiments, the lamp housing 200 can be a thin-walled structure, which can enhance the heat dissipation effect of the lamp housing 200.

[0035] In some embodiments, the lamp housing 200 has a mounting opening and a receiving space. In some embodiments, the lamp housing 200 may include a connecting plate 210 and a receiving structure 220. The mounting opening is formed on the side of the connecting plate 210 opposite to the receiving structure 220. The receiving structure 220 protrudes outward relative to the side of the connecting plate 210, and the receiving space is disposed inside the receiving structure 220.

[0036] In some embodiments, the housing structure 220 can be formed by a variety of methods, such as at least one of welding, stamping, casting, etc.

[0037] In some embodiments, the light-transmitting cover 300 is provided to cover the mounting opening so as to encapsulate the light-emitting component within the accommodating space.

[0038] The light-transmitting cover 300 is a transparent structure. In some embodiments, light emitted by the light-emitting component can pass through the light-transmitting cover 300, thereby creating a lighting effect.

[0039] In some embodiments, the light-transmitting cover 300 can be used to change the path of light, for example, to refract the light, to focus the light beam, or to disperse the light beam at least one of these methods. In some embodiments, the light-transmitting cover 300 can be made of various materials, such as glass, transparent plastic, etc.

[0040] The light-emitting component is used to provide illumination. In some embodiments, the light-emitting component may include a power source 310, a conductive structure 320, and at least one light-emitting element 330.

[0041] The power supply 310 is used to provide electrical energy. In some embodiments, the power supply 310 may be a rechargeable power supply. In some embodiments, the power supply 310 may be an external power source.

[0042] The conductive structure 320 is used to direct electrical energy from the power source 310 to at least one light-emitting element 330. In some embodiments, the conductive structure 320 may be electrically connected to the power source 310 and at least one light-emitting element 330 respectively, thereby forming a circuit between the power source 310 and at least one light-emitting element 330. In some embodiments, the conductive structure 320 may be disposed between the light-transmitting cover plate 300 and the power source 310. In some embodiments, the conductive structure 320 may include at least one of various structures, such as a circuit, a circuit board, etc.

[0043] The light-emitting element 330 is used to emit light when energized. In some embodiments, the light-emitting element 330 may include at least one of the following: a light bulb, a light-emitting diode, an LED chip, etc. In some embodiments, when the conductive structure 320 is a circuit board, the light-emitting element 330 may be integrated on the circuit board. In some embodiments, the light-emitting element 330 may be connected to the conductive structure 320 in various ways, such as in series, in parallel, or any combination thereof.

[0044] In some embodiments, at least one of the conductive structure 320, the light emitter 330, and the power supply 310 may be connected to the lamp housing 200 in a variety of ways, such as at least one of bonding, welding, threaded connection, abutment, snap-fit, etc., so as to facilitate the transfer of heat to the lamp housing 200.

[0045] In some embodiments, the receiving structure 220 can be a thin-walled structure, and the power supply 310 is connected to at least one inner side of the receiving structure 220 by various means, such as at least one of adhesive bonding, snap-fitting, and threaded connection, so that the receiving structure 220 can be used to dissipate heat from the power supply 310. Furthermore, by placing the power supply 310 within the receiving space of the receiving structure 220, the side of the power supply 310 away from the receiving structure 220 relative to the connecting plate 210 is prevented from protruding outwards, thus affecting the installation of the conductive structure 320, thereby improving the utilization rate of the internal space of the lamp housing 200.

[0046] In some embodiments, the light-transmitting cover plate 300 is provided with a plurality of light packets 301.

[0047] The light package 301 refers to a structure that bulges outward or is concave inward relative to the surface of the light-transmitting cover plate 300. In some embodiments, the light package 301 is correspondingly disposed with the light emitter 330, and the light emitted by each light emitter 330 can pass through the corresponding light package 301. The light package 301 can be used to change the path of the light emitted by the corresponding light emitter 330. In some embodiments, the light package 301 can be disposed on the side of the light-transmitting cover plate 300 away from and / or close to the light emitter 330. In some embodiments, the outer surface of the light package 301 can include various shapes, such as arc, semi-cylindrical, hemispherical, etc., and its specific shape can be set according to actual needs.

[0048] As an example only, the light package 301 can be located on the side of the light-transmitting cover plate 300 away from the light-emitting body 330. The outer surface of the light package 301 is a hemispherical surface, and the outer surface of the light package 301 near the light-emitting body 330 is a concave hemispherical surface. The centers of the corresponding spheres on the outer and inner surfaces of the light package 301 can coincide. After the light emitted by the light-emitting body 330 passes through the light package 301, it can be focused by the light package 301, thereby making the overall light emitted by the lamp more concentrated.

[0049] In some embodiments, such as Figure 5 , Figure 6 As shown, the light-transmitting cover 300 has a plurality of first connectors 302 along its contour edge. These first connectors 302 are spaced apart around the geometric center of the light-transmitting cover 300. The lamp housing 200 has a plurality of second connectors 212 corresponding one-to-one with the first connectors 302. The first connectors 302 and second connectors 212 are elastically engaged with each other along a first direction from the center to the edge of the light-transmitting cover 300 to fix the light-transmitting cover 300 and the lamp housing 200. In some embodiments, when the light-transmitting cover 300 is a body of revolution, the first direction can be the radial direction of the light-transmitting cover 300.

[0050] In some embodiments, the first connector 302 may be elastic. For example, the first connector 302 may be made of an elastic material, which may include at least one of elastic metals, elastic plastics, etc. As another example, the first connector 302 may be connected to the light-transmitting cover 300 via an elastic structure, which may include at least one of springs, spring sheets, etc. In some embodiments, when the first connector 302 is connected to the second connector 212, at least a portion of the first connector 302 may undergo elastic deformation.

[0051] In some embodiments, the second connector 212 may be elastic, and when the first connector 302 is connected to the second connector 212, the second connector 212 may be compressed and undergo elastic deformation. In some embodiments, the second connector 212 may be made of an elastic material, such as at least one of rubber, silicone, plastic, etc.

[0052] The elastic snap-fit ​​between the first connector 302 and the second connector 212 can be used to connect the light-transmitting cover 300 and the lamp housing 200. In some embodiments, the first connector 302 may include at least one bayonet structure 30221, and the second connector 212 may include at least one protrusion structure. The elastic snap-fit ​​between the first connector 302 and the second connector 212 can be achieved through the cooperation of the bayonet structure 30221 and the protrusion structure. For more information on the bayonet structure 30221, please refer to [link to relevant documentation]. Figure 7 Related descriptions.

[0053] During installation, the first connector 302 and / or the second connector 212 can adaptively undergo elastic deformation, thereby changing the first connector 302 and the second connector 212 from a separated state to a connected state. When it is necessary to separate the lamp housing 200 from the light-transmitting cover 300, a force can be manually applied to the first connector 302 and / or the second connector 212 to cause elastic deformation and separation.

[0054] In some embodiments, the first connector 302 can be connected to the light-transmitting cover 300 in a variety of ways, and the second connector 212 can be connected to the lamp housing 200 in a variety of ways, such as at least one of bonding, snap-fitting, welding, integral molding, etc.

[0055] In some embodiments, the first connector 302 may also be disposed on the lamp housing 200, and the second connector 212 may also be disposed on the light-transmitting cover plate 300.

[0056] Figure 7 This is a structural schematic diagram of the first connector and the second connector according to some embodiments of this specification.

[0057] like Figure 7 As shown, the first connector 302 includes a support portion 3021 and an elastic portion 3022.

[0058] The support portion 3021 can serve as an installation base for connecting the elastic portion 3022. In some embodiments, the support portion 3021 and the light-transmitting cover 300, and the support portion 3021 and the elastic portion 3022 can be connected in various ways, such as at least one of bonding, snap-fitting, welding, integral molding, etc.

[0059] In some embodiments, the support portion 3021 and / or the elastic portion 3022 may be elastic. For example, the support portion 3021 and / or the elastic portion 3022 may be made of an elastic material, which may include spring steel, etc. As another example, the support portion 3021 and / or the elastic portion 3022 may employ an elastic structure, which may include a spring, a spring sheet, etc. In some embodiments, the connection between the support portion 3021 and the elastic portion 3022 may be rounded to avoid stress concentration.

[0060] In some embodiments, the support portion 3021 extends away from the geometric center of the light-transmitting cover plate 300 along a first direction, and the elastic portion 3022 is connected to one end of the support portion 3021 away from the geometric center of the light-transmitting cover plate 300, and the elastic portion 3022 extends along a second direction perpendicular to the first direction (e.g., Figure 7 (Extends in the Z direction).

[0061] The second connector 212 can abut against the side of the elastic part 3022 near the geometric center of the light-transmitting cover 300.

[0062] In some embodiments, the elastic portion 3022 is connected to the end of the support portion 3021, thereby creating a certain gap between the elastic portion 3022 and the light-transmitting cover plate 300, which helps to enhance the elasticity of the first connector 302. Furthermore, it reduces the depth to which the second connector 212 is inserted into the elastic portion 3022 along the first direction. During the engagement or disengagement of the second connector 212 and the first connector 302, the resistance experienced by the first connector 302 is reduced, making the connection or disengagement of the lamp housing 200 and the light-transmitting cover plate 300 more convenient and improving the user experience.

[0063] In some embodiments, such as Figure 7 As shown, the elastic part 3022 is provided with a bayonet structure 30221.

[0064] The bayonet structure 30221 is used to engage with the second connector 212. In some embodiments, the bayonet structure 30221 may include a variety of elements, such as at least one of a slot or a hole. In some embodiments, the bayonet structure 30221 may be a slot formed along a second direction, with one end of the bayonet structure 30221 facing the support portion 3021 communicating with the outside of the elastic portion 3022, and the other end of the bayonet structure 30221 away from the support portion 3021 being closed.

[0065] The second connector 212 has a latching protrusion that engages with the latching structure 30221, and the latching protrusion has a first guide surface 2121 that guides the latching protrusion in and out of the latching structure 30221.

[0066] The card protrusion refers to the structure that protrudes outward relative to the housing 200.

[0067] The first guide surface 2121 is used to guide the movement direction of the elastic part 3022. In some embodiments, when the first connector 302 is engaged with the second connector 212, the first guide surface 2121 abuts against the elastic part 3022, and the first guide surface 2121 guides the elastic part 3022 away from the lamp housing 200.

[0068] In some embodiments, along the second direction, a first guide surface 2121 is provided on the side of the latching protrusion facing the support portion 3021. In some embodiments, the first guide surface 2121 may include a variety of structures, such as at least one of a wedge surface, an arc surface, at least a portion of a cylindrical surface, at least a portion of a spherical surface, etc.

[0069] During the process of fastening the first connector 302 and the second connector 212, the first guide surface 2121 can guide the elastic part 3022 to gradually undergo elastic deformation, thereby preventing the first connector 302 and the second connector 212 from jamming and making the fastening process of the first connector 302 and the second connector 212 smoother.

[0070] When the light-transmitting cover 300 needs to be fastened to the lamp housing 200, such as Figure 6 , Figure 7 As shown, the light-transmitting cover 300 is positioned along the second direction (e.g., Figure 7 The first connector 302 moves relative to the lamp housing 200 in the Z direction. The end of the elastic part 3022 first contacts the second connector 212. As the light-transmitting cover 300 continues to move, influenced by the second connector 212, the elastic part 3022 adaptively deforms, causing the end of the first connector 302 to move away from the light-transmitting cover 300, thus reducing installation difficulty. Until the second connector 212 enters the bayonet structure 30221 of the first connector 302, the force exerted by the second connector 212 on the elastic part 3022 disappears, and the elastic part 3022 resets under its own elastic action. The second connector 212 is then locked within the bayonet structure 30221 of the elastic part 3022, thereby achieving the locking connection between the light-transmitting cover 300 and the lamp housing 200.

[0071] When it is necessary to separate the light-transmitting cover 300 from the lamp housing 200, an external force can be applied to the elastic part 3022, for example, through manual operation. Under the action of the external force, the elastic part 3022 undergoes elastic deformation, for example, causing the end of the elastic part 3022 to move away from the light-transmitting cover 300. When the second connector 212 can disengage from the bayonet structure 30221 of the first connector 302, the light-transmitting cover 300 can be moved along the second direction (e.g., ...). Figure 7 The light-transmitting cover 300 can be separated from the lamp housing 200 by moving in the opposite direction to the Z direction (in the lamp housing 200).

[0072] In some embodiments, two support portions 3021 may be provided, with the two support portions 3021 located on both sides of the bayonet structure 30221, which helps to improve the connection strength between the first connector 302 and the light-transmitting cover plate 300, as well as the stability and elasticity of the first connector 302.

[0073] The cooperation between the first connector 302 and the second connector 212 facilitates the fastening or separation of the light-transmitting cover 300 and the lamp housing 200, thereby enabling the assembly or disassembly of the lamp fixture. This makes the assembly and disassembly of the lamp fixture convenient and quick, improving assembly and maintenance efficiency. The first connector 302 is also made elastic, allowing it to be easily and conveniently deformed by external force, further facilitating the assembly or disassembly of the first connector 302 and the second connector 212, further improving assembly and maintenance efficiency.

[0074] Figure 8 This is another structural schematic diagram of the first connector and the second connector shown in some embodiments of this specification.

[0075] In some embodiments, such as Figure 8 As shown, the latching protrusion may further include a second guide surface 2122, which is located on opposite sides of the latching protrusion, along with the first guide surface 2121. When the first connector 302 and the second connector 212 are fastened together, the elastic portion 3022 can abut against the second guide surface 2122.

[0076] During the separation of the elastic part 3022 from the second connector 212, the second guide surface 2122 can be used to guide the elastic part 3022 to gradually undergo elastic deformation, thereby causing the first connector 302 and the second connector 212 to gradually separate, avoiding jamming of the first connector 302 and the second connector 212 during the separation process, and making the separation process of the first connector 302 and the second connector 212 smoother.

[0077] In some embodiments, the second guide surface 2122 and the first guide surface 2121 may have the same or similar structures. Similarity means that the second guide surface 2122 and the first guide surface 2121 may have the same shape and different size parameters.

[0078] In some embodiments, the second guide surface 2122 may be provided with anti-slip patterns. The anti-slip patterns can increase the surface roughness of the second guide surface 2122, thereby increasing the friction between the second guide surface 2122 and the first connector 302. Without applying external force to the first connector 302, it is beneficial to prevent the first connector 302 from detaching from the second guide surface 2122.

[0079] The lamp housing 200 has a first enclosure 250 and a second enclosure 260. The first enclosure 250 surrounds the lamp housing 200 to form an installation opening, and the second enclosure 260 is arranged around the first enclosure 250 and spaced apart from the first enclosure 250.

[0080] Multiple sidewalls are connected between the first enclosure 250 and the second enclosure 260. A receiving cavity 211 for accommodating the first connector 302 is formed between the first enclosure 250, the second enclosure 260 and the sidewalls. The second connector 212 is disposed on the outer sidewall of the first enclosure 250 facing the second enclosure 260.

[0081] The first enclosure 250 and the second enclosure 260 may each include an annular thin-walled structure. In some embodiments, the edge of the lamp housing 200 may extend outward along a second direction to form the first enclosure 250, and the first enclosure 250 and the lamp housing 200 may be connected in a variety of ways, such as at least one of integral molding, bonding, welding, etc.

[0082] The sidewalls are used to connect the first enclosure 250 and the second enclosure 260. In some embodiments, the heat sink 240 may extend outward along a first direction to form a sidewall and be connected to the second enclosure 260 in a variety of ways, such as at least one of integral molding, bonding, welding, etc. More information about the heat sink 240 can be found in the related description below.

[0083] By providing the receiving cavity 211, after the lamp housing 200 is connected to the light-transmitting cover 300, the first connecting member 302 can be exposed inside the receiving cavity 211 relative to the interior of the housing 200. This avoids the first connecting member 302 being installed inside the lamp housing 200, which would make it difficult for the user to apply force to the first connecting member 302, making the installation and removal of the lamp housing 200 and the light-transmitting cover 300 more convenient. The first enclosure 250, the second enclosure 260, and the side wall can form a ring-shaped barrier, which can reduce the risk of accidental contact with the first connecting member 302.

[0084] The first enclosure 250 can also block the light-transmitting cover 300, preventing light transmitted from the light-transmitting cover 300 from overflowing along the first direction, thereby preventing light pollution.

[0085] In some embodiments, such as Figure 7 As shown, the accommodating cavity 211 has an opening, through which at least a portion of the first connector 302 extends or is exposed in the lamp housing 200. In some embodiments, the opening is located at one end of the accommodating cavity 211 away from the light-transmitting cover plate 300 along a second direction. When the first connector 302 is engaged with the second connector 212, the end of the first connector 302 can extend or be exposed in the lamp housing 200.

[0086] This allows the exposed portion of the end of the first connector 302 to be applied when it is necessary to separate the lamp housing 200 from the light-transmitting cover 300. This facilitates user operation and improves the user experience. In some embodiments, the outer surface of the end of the first connector 302 can be designed to be arc-shaped to avoid forming a sharp structure that could pose a safety risk.

[0087] In some embodiments, such as Figure 1 As shown, at least one heat sink 240 can be provided on the lamp housing 200.

[0088] The heat sink 240 has a sheet-like structure and can be made of metal materials, such as aluminum alloy or copper. The heat sink 240 can absorb heat from the lamp housing 200, thereby enhancing heat dissipation. In some embodiments, the heat sink 240 can be perpendicular to the lamp housing 200. Multiple heat sinks 240 can be evenly distributed on the lamp housing 200, and adjacent heat sinks 240 can be parallel or intersecting. The heat sink 240 can also serve as reinforcing ribs to increase the strength and rigidity of the lamp housing 200, thereby preventing deformation of the lamp housing 200.

[0089] In some embodiments, the heat sink 240 can be connected to the lamp housing 200 in a variety of ways, such as at least one of bonding, welding, integral molding, etc.

[0090] In some embodiments, such as Figure 5 , Figure 6 As shown, one side of the lamp housing 200 can be connected to the light-transmitting cover plate 300, and the conductive structure 320 and at least one light-emitting element 330 are disposed between the lamp housing 200 and the light-transmitting cover plate 300.

[0091] The lamp housing 200, used in conjunction with the light-transmitting cover plate 300, can restrict the position of the conductive structure 320 and the light-emitting element 330, ensuring their positional and shape accuracy and preventing displacement or deformation that could affect the lighting effect. In some embodiments, the light-transmitting cover plate 300 can apply pressure to the conductive structure 320 and the light-emitting element 330, allowing them to adhere tightly to the lamp housing 200, thereby enhancing heat dissipation.

[0092] In some embodiments, the lamp housing 200 and the light-transmitting cover 300 can also be connected by other means, such as at least one of adhesive bonding, threaded connection, etc.

[0093] According to some embodiments of the lamps provided in this specification, by elastically engaging the first connector 302 and the second connector 212, the light-transmitting cover 300 and the lamp housing 200 can be connected or separated as needed to meet different requirements such as assembly and maintenance, and to improve the efficiency of assembling and disassembling the lamps. The elasticity of the first connector 302 allows the user to manually apply force to it, facilitating the assembly or separation of the first connector 302 and the second connector 212, thereby further improving the efficiency of assembling and disassembling the lamps.

[0094] Figure 9 This is a schematic diagram showing the connection between the heat dissipation base plate and the light-transmitting cover plate according to some embodiments of this specification. Figure 10 This is a schematic diagram showing the connection between the elastic clip arm and the heat sink base plate according to some embodiments of this specification.

[0095] In some embodiments, such as Figure 3 , Figure 4 , Figure 9 , Figure 10 As shown, the support component 200 also includes a heat dissipation base plate 230.

[0096] The heat dissipation base plate 230 can be used to dissipate heat from the light-emitting components.

[0097] In some embodiments, the heat dissipation base plate 230 is disposed in the accommodating space facing the light-transmitting cover plate 300, the contour edge of the heat dissipation base plate 230 is connected to the lamp housing 200, and the heat dissipation base plate 230 is in contact with at least a portion of the light-emitting component, for example, in contact with the conductive structure 320 and / or the light-emitting body 330, so as to dissipate heat from the conductive structure 320 and / or the light-emitting body 330.

[0098] The combination of the heat dissipation base plate 230 and the lamp housing 200 can achieve full coverage of the conductive structure 320 and / or the light-emitting element 330, thereby increasing the effective heat dissipation area and facilitating the full heat dissipation of the conductive structure 320 and / or the light-emitting element 330, thus preventing the conductive structure 320 and / or the light-emitting element 330 from working in a high-temperature environment.

[0099] In some embodiments, the side of the heat dissipation base plate 230 near the conductive structure 320 is flush with the side of the lamp housing 200 near the conductive structure 320, so that the heat dissipation base plate 230 and the lamp housing 200 can fully contact the conductive structure 320, and avoid the formation of gaps between the heat dissipation base plate 230 and the conductive structure 320, and between the lamp housing 200 and the conductive structure 320, which would affect the heat dissipation effect.

[0100] In some embodiments, the heat dissipation base plate 230 and the lamp housing 200 can be connected in a variety of ways, such as at least one of adhesive bonding, snap-fitting, threaded connection, etc.

[0101] In some embodiments, a gap is formed between the heat dissipation base plate 230 and the power supply 310 to prevent the heat from the power supply 310 from being conducted to the heat dissipation base plate 230, thereby affecting the heat dissipation effect of the heat dissipation base plate 230 on the conductive structure 320.

[0102] In some embodiments, the conductive structure 320 may include a variety of shapes, such as at least one of planar, arc-shaped, spherical, wavy, and folded shapes. The side surface formed by the combination of the heat dissipation base plate 230 and the lamp housing 200 may be adapted to the shape of the conductive structure 320.

[0103] In some embodiments, such as Figure 9 , Figure 10 As shown, the heat dissipation base plate 230 has a connection hole 231 at its center, and the light-transmitting cover plate 300 has a plurality of spaced elastic locking arms 333, which pass through the connection hole 231 to elastically engage with the heat dissipation base plate 230. In some embodiments, the center of the heat dissipation base plate 230 may include at least one of the following: geometric center, center of gravity, etc.

[0104] The flexible clamp arm 333 extends along the light-transmitting cover 300 in the vertical direction toward the heat dissipation base plate 230.

[0105] When the elastic locking arm 333 is engaged with the connecting hole 231, it increases the connection strength between the light-transmitting cover plate 300 and the heat dissipation base plate 230. In some embodiments, multiple elastic locking arms 333 can be evenly distributed in a ring along the circumference of the connecting hole 231. This ensures that the heat dissipation base plate 230 and the light-transmitting cover plate 300 are subjected to uniform force after connection. When the elastic locking arm 333 is engaged with the connecting hole 231, the movement of the middle or near the middle of the light-transmitting cover plate 300 is restricted, which helps prevent warping of the middle or near the middle of the light-transmitting cover plate 300, thus affecting the shape accuracy of the light-transmitting cover plate 300 and preventing the illumination effect of the lamp from being affected.

[0106] In some embodiments, when the light-transmitting cover 300 is fastened to the lamp housing 200, the first connector 302 and the elastic locking arm 333 can move synchronously, and the connection between the first connector 302 and the second connector 212 and the connection between the elastic locking arm 333 and the connection hole 231 can be carried out synchronously.

[0107] In some embodiments, such as Figure 9 , Figure 10 As shown, the elastic locking arm 333 may include a locking rod 3331 and a locking protrusion 3332. The locking rod 3331 is provided on the light-transmitting cover plate 300, and the locking protrusion 3332 is provided on the outside of the locking rod 3331. The locking protrusion 3332 is locked onto the side of the heat dissipation base plate 230 away from the light-transmitting cover plate 300.

[0108] The fastening rod 3331 serves as a mounting base for installing the fastening protrusion 3332. One end of the fastening rod 3331 is connected to the heat dissipation base plate 230, and the other end is connected to the fastening protrusion 3332. In some embodiments, the fastening rod 3331 and the heat dissipation base plate 230, and the fastening rod 3331 and the fastening protrusion 3332, can be connected in various ways, such as at least one of adhesive bonding, welding, snap-fitting, and threaded connection. In some embodiments, the fastening rod 3331 can be perpendicular to the heat dissipation base plate 230.

[0109] When the light-transmitting cover 300 is fastened to the lamp housing 200, the fastening protrusion 3332 can abut against the inner side of the through hole. After the light-transmitting cover 300 and the lamp housing 200 are fastened together, the heat dissipation base plate 230 is fastened between the fastening protrusion 3332 and the light-transmitting cover 300. In some embodiments, the distance between the fastening protrusion 3332 and the light-transmitting cover 300 can be greater than or equal to the thickness of the heat dissipation base plate 230.

[0110] In some embodiments, the fastening rod 3331 and / or the fastening protrusion 3332 may be elastic. For example, the fastening rod 3331 and / or the fastening protrusion 3332 may be made of an elastic material, which may include spring steel, elastic plastic, etc. For another example, the fastening rod 3331 and the light-transmitting cover plate 300 may be connected by an elastic structure, which may include a spring, spring sheet, etc. By making the fastening rod 3331 and / or the fastening protrusion 3332 elastic, when the light-transmitting cover plate 300 is fastened to the lamp housing 200, the fastening rod 3331 and / or the fastening protrusion 3332 can adaptively deform elastically, avoiding jamming. In some embodiments, after the light-transmitting cover plate 300 and the lamp housing 200 are fastened, the fastening rod 3331 may be in a compressed state, thereby applying a clamping force to the heat dissipation base plate 230 using the fastening rod 3331, thereby improving the connection strength between the elastic locking arm 333 and the connecting hole 231.

[0111] In some embodiments, such as Figure 10 The fastening protrusion 3332 may include a third guide surface 33321.

[0112] The third guiding surface 33321 refers to the surface where the fastening protrusion 3332 contacts the heat dissipation base plate 230 during the fastening process between the light-transmitting cover plate 300 and the lamp housing 200.

[0113] In some embodiments, the third guide surface 33321 may include at least one of various shapes, such as a wedge shape, an arc shape, a cylindrical portion, a spherical portion, etc. During the fastening process between the light-transmitting cover 300 and the lamp housing 200, the inner side of the through hole on the heat dissipation base plate 230 can apply pressure to the fastening protrusion 3332 through the third guide surface 33321, thereby guiding the fastening rod 3331 to gradually deform until the fastening protrusion 3332 completely passes through the through hole. The fastening rod 3331 then recovers under its own elasticity, thereby enabling the elastic locking arm 333 to fasten with the connecting hole 231. This makes the connection between the elastic locking arm 333 and the connecting hole 231 smoother and avoids jamming.

[0114] In some embodiments, the snap-fit ​​protrusion 3332 may include a fourth guide surface 33322.

[0115] The fourth guide surface 33322 refers to the surface where the fastening protrusion 3332 contacts the heat dissipation base plate 230 during the separation of the light-transmitting cover plate 300 from the lamp housing 200.

[0116] In some embodiments, the fourth guide surface 33322 may include at least one of various shapes, such as a wedge shape, an arc shape, a cylindrical portion, a spherical portion, etc. During the separation of the light-transmitting cover 300 from the lamp housing 200, the inner side of the through hole on the heat dissipation base plate 230 can apply pressure to the fastening protrusion 3332 through the fourth guide surface 33322, thereby guiding the fastening rod 3331 to gradually deform until the fastening protrusion 3332 completely passes through the through hole. The fastening rod 3331 then recovers under its own elasticity, thereby separating the elastic locking arm 333 from the connecting hole 231. This makes the separation of the elastic locking arm 333 from the connecting hole 231 smoother and avoids jamming.

[0117] In some embodiments, the third guide surface 33321 and the fourth guide surface 33322 are two opposite sides of the snap-fit ​​protrusion 3332. By employing the third guide surface 33321 and the fourth guide surface 33322, during the snap-fitting or separating process of the light-transmitting cover 300 and the lamp housing 200, the elastic locking arm 333 can adaptively deform without manual or tool operation, making the connection or separation of the elastic locking arm 333 and the connecting hole 231 simple and quick, which is beneficial to improving the user experience.

[0118] In some embodiments, a sealing structure is provided between the light-transmitting cover plate 300 and the lamp housing 200.

[0119] The sealing structure is used to seal the gap between the light-transmitting cover plate 300 and the lamp housing 200, preventing moisture, dust, and other impurities from entering the interior of the lamp through the gap and causing contamination or damage to the interior, thus helping to ensure the lifespan of the lamp. In some embodiments, the sealing structure may include various types, such as a labyrinth seal structure, a sealing ring, a sealant, or any combination thereof.

[0120] Figure 11 This is a schematic diagram of the installation of the sealing ring according to some embodiments of this specification. Figure 12 This is a cross-sectional schematic diagram of the sealing ring shown in some embodiments of this specification.

[0121] like Figure 11 As shown, a sealing ring 400 is provided between the light-transmitting cover plate 300 and the lamp housing 200.

[0122] The sealing ring 400 has an annular structure. In some embodiments, the sealing ring 400 can be clamped between the light-transmitting cover plate 300 and the lamp housing 200. In some embodiments, the sealing ring 400 can be made of an elastic material, such as at least one of rubber, silicone, and plastic. After the light-transmitting cover plate 300 and the lamp housing 200 are fastened together, the sealing ring 400 can be in a compressed state, thereby increasing the sealing effect of the sealing ring 400.

[0123] In some embodiments, such as Figure 11 As shown, the light-transmitting cover plate 300 is provided with a sealing groove 334.

[0124] A sealing groove 334 is used to limit the position of the sealing ring 400. In some embodiments, one sealing groove 334 may be provided, and the sealing groove 334 may be annular and distributed around the circumference of the light-transmitting cover plate 300, with the sealing ring 400 disposed within the sealing groove 334. In some embodiments, the shape of the sealing groove 334 may be adapted to the shape of the sealing ring 400. In some embodiments, multiple sealing grooves 334 may be provided, and the multiple sealing grooves may be annularly distributed along the circumference of the light-transmitting cover plate 300. A portion of the sealing ring 400 may be connected to one of the multiple sealing grooves 334 respectively.

[0125] By using the sealing groove 334 to restrict the position of the sealing ring 400, the positional accuracy of the sealing ring 400 can be improved, preventing the sealing ring 400 from falling off and causing sealing failure. In some embodiments, the sealing groove 334 can be formed by various methods, such as at least one of machining, welding, and stamping. In some embodiments, the inner surface of the sealing groove 334 can compress at least a portion of the sealing ring 400, thereby deforming at least a portion of the sealing ring 400 under pressure. This increases the contact area between the sealing ring 400 and the sealing groove 334, and the sealing ring 400 applies pressure to the sealing groove 334 under its own elasticity, thereby improving the connection strength between the sealing ring 400 and the sealing groove 334 and the sealing performance of the sealing ring 400.

[0126] In some embodiments, such as Figure 12 As shown, the sealing ring 400 has at least one first sealing protrusion 410 on the side facing the sealing groove 334.

[0127] The first sealing protrusion 410 refers to a structure that protrudes outward relative to the side of the sealing ring 400 facing the sealing groove 334. The first sealing protrusion 410 can be used to increase the radial width of the sealing ring 400, thereby facilitating full contact between the sealing ring 400 and the sealing groove 334.

[0128] In some embodiments, the first sealing protrusion 410 is annular and is arranged circumferentially along the sealing ring 400, so that the first sealing protrusion 410 can fully contact the sealing groove 334 in the circumferential direction. In some embodiments, multiple first sealing protrusions 410 can be provided, for example, two, three or other numbers, the specific number of which can be set according to actual needs. At least one first sealing protrusion 410 is provided on both the inner and outer surfaces of the sealing ring 400. After the sealing ring 400 is connected to the sealing groove 334, the first sealing protrusion 410 is compressed and undergoes elastic deformation. The gap between the sealing ring 400 and the sealing groove 334 can provide sufficient deformation space for the elastic deformation of the first sealing protrusion 410, thereby preventing the first sealing protrusion 410 from being crushed.

[0129] In some embodiments, the cross-section of the first sealing protrusion 410 may include various shapes, such as triangle, semicircle, semi-ellipse, etc., and its specific shape can be set according to actual needs. The cross-section of the first sealing protrusion 410 refers to the virtual cross-section formed after the first sealing protrusion 410 is cut off by a virtual plane passing through the axis of the sealing ring 400.

[0130] In some embodiments, the cross-section of the sealing groove 334 may include various shapes, such as U-shaped, L-shaped, V-shaped, T-shaped, etc., and the specific shape can be set according to actual needs. The cross-section of the sealing groove 334 refers to the virtual cross-section formed after the sealing groove 334 is cut off by a virtual plane passing through the axis of the sealing ring 400.

[0131] In some embodiments, such as Figure 11 As shown, a limiting plate 214 is provided on the lamp housing 200.

[0132] The limiting plate 214 is used to limit the position of the sealing ring 400. In some embodiments, at least a portion of the limiting plate 214 may extend into the sealing ring 400.

[0133] In some embodiments, a limiting groove 420 is provided on the sealing ring 400.

[0134] The limiting groove 420 is used to position the limiting plate 214. At least a part of the limiting plate 214 can extend into the limiting groove 420. The cooperation between the limiting plate 214 and the limiting groove 420 restricts the relative position of the sealing ring 400 and the lamp housing 200, thereby helping to ensure the positional accuracy of the sealing ring 400.

[0135] In some embodiments, the limiting plate 214 can be annular, and the limiting plate 214 is arranged along the circumference of the lamp housing 200, and the limiting groove 420 is also annular.

[0136] In some embodiments, multiple limiting plates 214 can be provided, and the multiple limiting plates 214 can be distributed in a ring along the circumference of the lamp housing 200. The number of limiting grooves 420 is the same as the number of limiting plates 214, and the limiting grooves 420 are correspondingly provided with the limiting plates 214.

[0137] In some embodiments, the outer surface of the limiting plate 214 can compress at least a portion of the sealing ring 400, thereby deforming at least a portion of the sealing ring 400 to increase the contact area and connection strength between the sealing ring 400 and the limiting plate 214, thereby enhancing the sealing effect of the sealing ring 400.

[0138] In some embodiments, at least one second sealing protrusion 430 is provided on the side of the limiting groove 420.

[0139] The second sealing protrusion 430 refers to a structure that protrudes outward relative to the side of the limiting groove 420. In some embodiments, the limiting plate 214 can compress the second sealing protrusion 430, causing the second sealing protrusion 430 to undergo elastic deformation and increasing the contact area between the second sealing protrusion 430 and the limiting plate 214, thereby improving the sealing effect between the sealing ring 400 and the limiting plate 214.

[0140] In some embodiments, multiple layers of limiting plates 214 can be provided along the radial direction of the lamp housing 200, for example, two layers or other quantities, the specific number of which can be set according to actual needs. The limiting groove 420 is provided correspondingly to each layer of limiting plates 214. By providing multiple layers of limiting plates 214, the connection strength and sealing effect between the sealing ring 400 and the limiting plates 214 can be further enhanced.

[0141] In some embodiments, the cross-section of the limiting groove 420 may include various shapes, such as at least one of triangles, semicircles, rectangles, or any combination thereof. The shape of the limiting plate 214 may be adapted to the shape of the limiting groove 420.

[0142] In some embodiments, the limiting plate 214 can extend into the sealing groove 334, and the sealing ring 400 can be disposed between the limiting plate 214 and the sealing groove 334, thereby increasing the complexity of the gap between the light-transmitting cover plate 300 and the lamp housing 200. In conjunction with the sealing ring 400, the area of ​​the sealing ring 400 being compressed can be further increased, thereby improving the sealing effect of the sealing ring 400.

[0143] In some embodiments, the outer surface of the limiting plate 214 and the inner surface of the sealing groove 334 can be designed to be wavy. Alternatively, at least one protrusion can be provided on the outer surface of the limiting plate 214 and the inner surface of the sealing groove 334. By adopting a wavy design or protrusion, the crests or protrusions of the wavy shape can be used to apply local pressure to the sealing ring 400, thereby increasing the connection strength between the limiting plate 214 and the sealing ring 400, and between the sealing groove 334 and the sealing ring 400.

[0144] In some embodiments, the luminaire may also include a connection component 100.

[0145] The connecting component 100 is used to connect with a preset carrier to fix the luminaire. The preset carrier may include mounting structures located at multiple installation positions. The mounting structures may include at least one of the following: hole-shaped, rod-shaped, ring-shaped, hook-shaped, etc. The installation positions may include at least one of the following: wall, ceiling, column, frame, etc.

[0146] In some embodiments, the connecting component 100 and the light-transmitting cover 300 may be respectively disposed on opposite sides of the lamp housing 200, so as to facilitate the light-transmitting cover 300 facing the position that needs to be illuminated by light.

[0147] The connecting assembly 100 includes a support 110 disposed on the lamp housing 200 and a connecting structure 120 connected to the support 110.

[0148] The support 110 can serve as a mounting base and be connected to the connection structure 120. In some embodiments, the support 110 and the lamp housing 200 can be connected in various ways, such as at least one of snap-fit, welding, threaded connection, integral molding, etc.

[0149] By using the support 110, the connection structure 120 is not directly connected to the lamp housing 200, thus avoiding the risk of damage to the lamp housing 200 due to direct force.

[0150] In some embodiments, the connection structure 120 includes a connecting rod portion and a mounting portion connected to each other. The connecting rod portion is rotatably connected to the support 110, and the rotation center of the connecting rod portion is parallel to the first direction. The mounting portion is used to connect a preset carrier and has a hook-shaped structure.

[0151] In some embodiments, the connecting rod can be rotatably connected to the support 110. In some embodiments, the connecting rod can be rotated to be parallel or nearly parallel to the lamp housing 200, thereby reducing the space occupied by the connecting structure 120 and facilitating the packaging or transportation of the entire lamp. When the lamp needs to be installed, the connecting rod can be rotated to form a certain angle with the lamp housing 200, such as 45°, 90° or other arbitrary angles, thereby facilitating the connection between the connecting structure 120 and the preset carrier and preventing the lamp from colliding.

[0152] In some embodiments, such as Figure 3 , Figure 4 As shown, the luminaire may also include a controller 361, which is capable of analyzing and processing data. In some embodiments, the controller 361 may store a preset program, and the controller 361 may run the preset program to achieve control functions. In some embodiments, the controller 361 may include various types, such as a microprocessor, a ZHAGA controller, etc.

[0153] In some embodiments, the controller 361 may be communicatively connected to the conductive structure 320. The controller 361 may control the conductive structure 320 to perform various functions based on a preset program. For example, it may control at least one of the following: connecting, disconnecting, or connecting based on a preset periodicity, in at least a portion of the circuit in the conductive structure 320.

[0154] In some embodiments, the controller 361 can control the conductive structure 320 based on preset conditions. These preset conditions can be preset values, which can be set according to actual needs and stored in the controller 361. In some embodiments, the controller 361 can be communicatively connected to a sensor, and the preset conditions can include the sensor detecting corresponding sensing data. The sensor can include at least one of a sound sensor, a human body sensor, a light sensor, etc.

[0155] As an example only, the preset conditions may include: if the loudness of the sound signal detected by the sound sensor is greater than a loudness threshold, the controller 361 controls a portion of the circuit in the conductive structure 320 to be connected, thereby controlling at least a portion of the light emitter 330 to emit light. If the duration of the sound signal not detected by the sound sensor is greater than a duration threshold, the controller 361 controls the entire conductive structure 320 to be disconnected.

[0156] For example, the preset conditions may also include the human body sensor detecting at least one person, and the controller 361 controlling a portion of the circuit in the conductive structure 320 to connect, thereby controlling at least a portion of the light-emitting element 330 to emit light. If the human body sensor does not detect a person, the controller 361 controlling the conductive structure 320 to completely disconnect.

[0157] For example, the preset conditions may also include: if the light intensity detected by the light sensor is lower than a first intensity threshold, the controller 361 controls a portion of the circuit in the conductive structure 320 to be connected, thereby controlling at least a portion of the light emitter 330 to emit light; if the light intensity detected by the light sensor is greater than a second intensity threshold, the controller 361 controls the circuit in the conductive structure 320 to be disconnected. The loudness threshold, duration threshold, first intensity threshold, and second intensity threshold are preset values ​​and can be set according to actual needs.

[0158] In some embodiments, the controller 361 may be connected to the light-transmitting cover 300 in a variety of ways, such as at least one of adhesive bonding, snap-fitting, threaded connection, etc.

[0159] In some embodiments, the controller 361 may be electrically connected to the power supply 310, and the power supply 310 may be used to power the controller 361.

[0160] By setting up controller 361, the lighting fixtures can be automatically controlled, improving the level of automation. Controller 361 can also automatically determine whether the lighting fixtures need to provide illumination and adjust the light intensity, thereby improving energy efficiency and avoiding energy waste.

[0161] In some embodiments, such as Figure 3 , Figure 4 As shown, a switch structure 351 is electrically connected between the power supply 310 and the conductive structure 320. The switch structure 351 is configured to control the number of light-emitting elements 330 forming the path.

[0162] In some embodiments, the switch structure 351 may include multiple interconnected states of different degrees, with each interconnected state corresponding to a different number of light-emitting elements 330 forming a path. For example, the switch structure 351 may include a first-level interconnected state, a second-level interconnected state, and a third-level interconnected state. The number of light-emitting elements 330 forming a path corresponding to the first-level interconnected state is one-third of the total number of light-emitting elements, the number of light-emitting elements 330 forming a path corresponding to the second-level interconnected state is two-thirds of the total number of light-emitting elements, and the number of light-emitting elements 330 forming a path corresponding to the third-level interconnected state is three-thirds of the total number of light-emitting elements. Thus, the number of light-emitting elements 330 forming a path can be controlled by the switch structure 351 according to actual needs.

[0163] In some embodiments, the switch structure 351 may include multiple switch circuits, which may correspond to multiple different levels of connectivity. The switch structure 351 may also include one or more switches. When using a single switch, the switch can selectively connect to one of the multiple switch circuits. When using multiple switches, each switch is connected to a corresponding switch circuit, and the user can connect one of the switches and its corresponding switch circuit according to actual needs, thereby allowing the switch structure 351 to switch to different connectivity states.

[0164] In some embodiments, the connection state of the switch structure 351 can be adjusted in a variety of ways, such as manual adjustment, electric adjustment, etc. When electric adjustment is used, the switch in the switch structure 351 can be an electromagnetic switch, which can be communicatively connected to the controller 361, and the controller 361 can automatically control the electromagnetic switch.

[0165] In some embodiments, the switch structure 351 may include a DIP switch control board.

When the switch hole is closed, the receiving structure 220 can be closed to achieve a sealing effect. In some embodiments, the plug 353 and the switch hole can be connected in a variety of ways, such as at least one of snap-fit, fastening, threaded connection, etc. In some embodiments, at least a portion of the plug 353 can be elastic, and when the plug 353 is connected to the switch hole, at least a portion of the plug 353 can be compressed and undergo elastic deformation, thereby improving the connection strength and sealing performance between the plug 353 and the switch hole.

[0170] In some embodiments, the receiving structure 220 is provided with a wiring channel, through which external wiring can pass and be electrically connected to the power supply 310. The external wiring may include at least one of the following: wires, cables, network cables, etc. In some embodiments, the wiring channel is provided with a wiring limiting structure 370.

[0171] The line limiting structure 370 is used to connect with external lines, reduce the gap between the external lines and the housing structure 220, improve the stability of the external lines, and enhance the sealing between the external lines and the housing structure 220.

[0172] In some embodiments, the line limiting structure 370 may include a tubular structure, and the outer side of the line limiting structure 370 is connected to the receiving structure 220 in various ways, such as snap-fit ​​or threaded connection. The inner hole of the line limiting structure 370 is connected to the external line.

[0173] In some embodiments, the inner hole of the line limiting structure 370 and the external line can be elastically connected in various ways. For example, the line limiting structure 370 can be made of an elastic material. As another example, at least one elastic structure can be provided inside the inner hole of the line limiting structure 370. When the external line passes through the inner hole of the line limiting structure 370, the elastic structure contacts the external line and undergoes elastic deformation, applying pressure to the external line using the elasticity of the elastic structure. The elastic structure may include at least one elastic baffle made of an elastic material. Multiple elastic baffles may be distributed in a ring along the circumference of the inner hole of the limiting structure 370. The elastic material may include at least one of rubber, silicone, plastic, etc.

[0174] In some embodiments, the line limiting structure 370 may include a PG head.

[0175] In some embodiments, an emergency plug 341 is connected to the outside of the receiving structure 220. The emergency plug 341 can be electrically connected to the conductive structure 320 and / or the power supply 310.

[0176] Emergency plug 341 is used to connect to a backup power source. The backup power source may include at least one of a generator, a battery, etc. When a power outage occurs and the power source 310 cannot obtain power from the grid through an external line, resulting in the lamps being unable to provide illumination, the emergency plug 341 can be used to connect to the backup power source to provide power to the lamps.

[0177] In some embodiments, the receiving structure 220 is provided with a plug support 343, at least a portion of which can pass through the receiving structure 220 and be electrically connected to an emergency plug 341. The emergency plug 341 is electrically connected to the conductive structure 320 and / or the power supply 310 through the plug support 343. Using the plug support 343 to connect the emergency plug 341 can improve the stability of the emergency plug 341 and reduce damage to the receiving structure 220.

[0178] In some embodiments, the plug holder 343 and the receiving structure 220 can be connected in various ways, such as snap-fit, threaded connection, etc. In some embodiments, at least a portion of the plug holder 343 can extend outward through the receiving structure 220. The outwardly extending portion of the plug holder 343 includes external threads, and a locking nut 342 is connected to the external threads. The plug holder 343 is fixed to the receiving structure 220 by the engagement of the locking nut 342 and the external threads. The emergency plug 341 is located on the outside of the receiving structure 220, which facilitates the installation or removal of the emergency plug 341 as needed. For example, when not in use, the emergency plug 341 can be removed and stored to avoid it occupying extra space or posing a risk of damage. When needed, the emergency plug 341 is connected to the plug holder 343. The connection point between the plug holder 343 and the emergency plug 341 is located on the outside of the receiving structure 220, which also facilitates the installation of the emergency plug 341.

[0179] In some embodiments, the portion of the plug holder 343 extending out of the receiving structure 220 may be connected to a protective cover. The protective cover serves to prevent water and dust from entering the plug holder 343 and affecting its normal use.
