[0032] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0033] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0034] The lighting device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0035] refer to Figures 1 to 11As shown, the embodiment of the present application discloses a lighting device, which is, for example, a ceiling lamp. Specifically, the disclosed lighting device includes: a first housing 110 , a first light source module 210 , a first transparent cover 310 and a stopper 400 .

[0036] refer to Fig.10 As shown, the bottom surface of the first housing 110 is provided with a first light outlet 115, the top and bottom ends of the first housing 110 are respectively provided with a first limiting portion 111 and a second limiting portion 112, and the first light source module 210 is opposite to the first light outlet 115 to emit light to the first light outlet 115. The first limiting portion 111 is, for example, a first annular flange extending toward the center of the first housing 110 along the radial direction of the first housing 110, and the second limiting portion 112 is, for example, a second annular flange extending toward the center of the first housing 110 along the radial direction of the first housing 110.

[0037] refer to Figure 6 As shown, the first transparent cover 310 is disposed in the first housing 110 and blocks the first light outlet 115 , and the first transparent cover 310 cooperates with the second limiting portion 112 in the axial direction of the first housing 110 .

[0038] refer to Figure 6 As shown, the limit member 400 is arranged in the first shell body 110, and the top end of the limit member 400 cooperates with the first limit portion 111 in the axial direction of the first shell body 110 for upper limit positioning, and the bottom end of the limit member 400 cooperates with the first transparent cover 310 in the axial direction of the first shell body 110 for upper limit positioning, so as to clamp the first transparent cover 310 between the limit member 400 and the second limit portion 112.

[0039] In the embodiment of the present application, the first transparent cover 310 is arranged in the first shell 110, and the top and bottom of the first shell 110 are respectively provided with a first limiting portion 111 and a second limiting portion 112, and the first transparent cover 310 and the second limiting portion 112 are matched in the upper limit position in the axial direction of the first shell 110. At the same time, a limiting member 400 is arranged in the first shell 110, and the top of the limiting member 400 is matched with the first limiting portion 111 in the upper limit position in the axial direction of the shell, and the bottom of the limiting member 400 is matched with the first transparent cover 310 in the upper limit position in the axial direction of the shell. In this way, the first transparent cover 310 can be clamped between the limiting member 400 and the second limiting portion 112, so that the first transparent cover 310 can be connected to the first shell 110 without drilling a hole in the first transparent cover 310. Compared with the solution of connecting the first transparent cover 310 to the first shell 110 by means of screws, the solution adopted in the embodiment of the present application will not damage the structural integrity of the first transparent cover 310, thereby extending the service life of the first transparent cover 310.

[0040] As a specific implementation, the first transparent cover 310 is, for example, a deformable cover. When the first transparent cover 310 is disassembled, the second limit portion 112 will limit the first transparent cover 310 from entering and exiting the first shell 110. By configuring the first transparent cover 310 as a deformable cover, the first transparent cover 310 can be deformed under the action of external force, so that the first transparent cover 310 can enter and exit the first shell 110 more conveniently.

[0041] In another embodiment, the number of the stoppers 400 is, for example, at least two, and the stoppers 400 are, for example, arranged at intervals along the circumference of the first shell 110. In this way, the number of the stoppers 400 is large, so that the movement of the first transparent cover 310 in the axial direction of the first shell 110 can be better limited. It can be understood that the more the number of the stoppers 400 is, the lower the possibility of the first transparent cover 310 moving in the axial direction of the first shell 110, and accordingly, the better the stability of the first transparent cover 310.

[0042] Of course, in other optional embodiments, the number of the limiting member 400 may also be one.

[0043] In another embodiment, reference Fig. 9 As shown, the bottom end of the stopper 400 is provided with a first protrusion 410, and the first protrusion 410 cooperates with the top surface of the first transparent cover 310 in the axial direction of the first shell 110 to limit the position, and the first protrusion 410 is, for example, a strip-shaped structure. With such a configuration, when the first transparent cover 310 is disassembled, the contact area between the first transparent cover 310 and the stopper 400 is small, so that the friction force on the first transparent cover 310 is small, so that the disassembly and assembly of the first transparent cover 310 is more convenient, and the service life of the first transparent cover 310 can be extended.

[0044] In other optional embodiments, the limiting member 400 may not be provided with the first protrusion 410 . In this case, the bottom surface of the limiting member 400 as a whole cooperates with the top surface of the first transparent cover 310 in the axial direction of the first shell 110 for limiting positioning.

[0045] In another embodiment, reference Fig. 9 As shown, the bottom end of the stopper 400 is provided with a second protrusion 420, which is located between the first transparent cover 310 and the first shell 110, and cooperates with the first transparent cover 310 to limit the position in a direction perpendicular to the axis of the first shell 110, and the second protrusion 420 is, for example, a sheet-like structure. In this way, the second protrusion 420 can limit the movement of the first transparent cover 310 in a direction perpendicular to the axis of the first shell 110, so that the stability of the first transparent cover 310 is better.

[0046] In other optional embodiments, the second protrusion 420 may not be provided at the bottom end of the limiting member 400 .

[0047] Furthermore, the first transparent cover 310 is, for example, a circular cover, the second raised portion 420 is, for example, an arc-shaped structure, and the second raised portion 420 fits the first transparent cover 310, that is, the curvatures of the two are consistent. In this way, the contact area between the second raised portion 420 and the first transparent cover 310 is large, so that the stability of the first transparent cover 310 is further improved.

[0048] In a further embodiment, reference Fig. 9 As shown, the bottom end of the limiting cover may be provided with both the first protruding portion 410 and the second protruding portion 420 mentioned above.

In this arrangement, at least part of the first electrical connection line 510 is hidden inside the stopper 400, so that the lighting device as a whole is more compact, and this can also reduce the possibility of interference between the first electrical connection line 510 and other components.

[0050] In other optional embodiments, the limiting member 400 may not be provided with a threading channel.

[0051] In a further embodiment, reference Figure 7 As shown, the first electrical connection line 510 is a double-insulated line. The double-insulated line has at least two insulating layers arranged in sequence from the inside to the outside, which makes the double-insulated line have better rigidity and is not easy to deform and sag under the action of gravity. In this way, the position of the first electrical connection line 510 can be fixed without using a fixing part or with fewer fixing parts, so that the structure of the lighting device is relatively simple. Specifically, the fixing part is, for example, a buckle.

[0052] In other optional embodiments, the first electrical connection line 510 may also be a single insulating line, which includes only one insulating layer.

[0053] In a further embodiment, reference Figure 7 and Fig. 9 As shown, a concave cavity 440 is provided on one side of the side wall of the stopper 400 facing the first housing 110, and a wire hole 430 is provided on the stopper 400. The wire hole 430 is connected to the inner cavity of the first housing 110 and the concave cavity 440, and the wire threading channel includes the wire hole 430 and the concave cavity 440. The concave cavity 440 is an open structure, so that the user can repair or replace the first electrical connection line 510 more conveniently.

[0054] In other optional embodiments, the threading channel may also be a cylindrical channel, one end of which extends to a side of the limit member 400 facing the side wall of the first shell 110 , and the other end of the arc channel is connected to the above-mentioned threading hole 430 .

The line-passing groove 431 is also an open structure, so that the disassembly or maintenance of the first electrical connection line 510 is more convenient. In addition, with such a configuration, the line-passing groove 431 can limit the movement of the first electrical connection line 510 toward the center of the first shell 110, so that the first electrical connection line 510 is not easy to block light.

[0056] In other optional embodiments, the wire passing hole 430 is, for example, a circular hole, and the wire passing hole 430 is, for example, disposed on a side of the side wall of the limiting member 400 facing away from the first shell 110 .

[0057] In a further embodiment, reference Figure 4 and Figure 8 As shown, the lighting device further includes: a second housing 120, a second transparent cover 320 and a second light source module 220. The second housing 120 is sleeved outside the first housing 110, and the axes of the two are parallel. The outer side of the second housing 120 is provided with a second light outlet. The second transparent cover 320 is sleeved outside the second housing 120 and blocks the second light outlet. The second light source module 220 is arranged in the inner cavity of the second housing 120 and faces the second transparent cover 320 to emit light to the second transparent cover 320. With such arrangement, when the first light source module 210 and the second light source module 220 are turned on separately or the first light source module 210 and the second light source module 220 are turned on at the same time, the lighting device presents different lighting effects respectively, so that the lighting device can provide richer visual effects, so that the lighting device can better meet the needs of users.

[0060] In a further embodiment, the inner side wall of the second housing 120 is tangent to the outer side wall of the first housing 110, the first threading hole 113 is provided at a position where the first housing 110 and the second housing 120 are tangent, the second threading hole 121 is provided at a position where the second housing 120 and the first housing 110 are tangent, the first threading hole 113 and the second threading hole 121 are opposite and connected, the first electrical connection line 510 passes through the threading channel, the first threading hole 113 and the second threading hole 121 in sequence, and is electrically connected to the second light source module 220, and the first electrical connection line 510 is, for example, a power line of the second light source module 220. With such a configuration, the distance between the first threading hole 113 and the second threading hole 121 is shorter, so that the length of the first electrical connection line 510 is shorter, thereby reducing the cost of the lighting device. In addition, with such a configuration, there is no exposed first electrical connection line 510 between the first housing 110 and the second housing 120, thereby reducing the possibility of interference between the first electrical connection line 510 and other structures.

[0061] In other optional embodiments, there may not be a tangent relationship between the inner wall of the second shell 120 and the outer wall of the first shell 110, and the axis of the first shell 110, for example, coincides with the axis of the second shell 120, and the first shell 110 and the second shell 120, for example, are both cylindrical structures, and the outer diameter of the first shell 110 is, for example, smaller than the inner diameter of the second shell 120.
