[0047] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The ceiling assembly disclosed in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0049] Please refer to Figure 1-Figure 11 The present application discloses a ceiling assembly, which includes a hanger 100, a mounting plate 300 and a power supply assembly 400.

[0050] The ceiling assembly disclosed in the present application is used to be connected to the lamp body 200, specifically, the bracket 100 of the ceiling assembly is used to be connected to the lamp body 200, and the bracket 100 is the basic component of the ceiling assembly, which can provide an installation basis for other components of the ceiling assembly, such as providing an installation basis for the mounting plate 300 and the power supply assembly 400.

[0051] The bracket 100 is provided with a first through hole 130 and a first limiting groove 140. The first limiting groove 140 is used to abut against a partial structure of the lamp body 200 in the thickness direction of the ceiling assembly so that the lamp body 200 can be hung on the bracket 100. The partial structure of the lamp body 200 can specifically be the first protrusion 220 of the lamp body 200 described later.

[0052] The mounting plate 300 is detachably connected to the rack 100. For details, please refer to Figure 1 A fourth through hole 340 is provided on the mounting plate 300, a columnar connecting portion 193 is protruded on the bracket 100, one end of the second connecting member 620 passes through the fourth through hole 340 and is connected to the columnar connecting portion 193, the second connecting member 620 can be a threaded connecting member, a threaded hole is provided on the columnar connecting portion 193, and the second connecting member 620 is threadedly matched with the threaded hole so that the mounting plate 300 and the bracket 100 can be detachably connected.

[0053] In an optional embodiment, the number of the second connecting members 620, the fourth through holes 340 and the columnar connecting portions 193 can be at least two, each of the fourth through holes 340 and each of the second connecting members 620 is spaced apart in the circumferential direction of the mounting plate 300, each of the columnar connecting portions 193 is spaced apart on the bracket 100, and each of the second connecting members 620, each of the fourth through holes 340 and each of the columnar connecting portions 193 corresponds one by one to improve the connection stability between the mounting plate 300 and the bracket 100.

[0054] When the mounting plate 300 is connected to the bracket 100, the mounting plate 300 and the bracket 100 enclose an installation space 310 that is connected to the first through hole 130, and the bracket 100 is located between the mounting plate 300 and the lamp body 200, and the power supply assembly 400 is arranged in the installation space 310. Specifically, the power supply assembly 400 is limited in the installation space 310, and a limiting buckle 192 is protruding on the bracket 100, and the power supply assembly 400 is limited in position with the limiting buckle 192, and specifically, the circuit board 420 of the power supply assembly 400 described later is limited in position with the limiting buckle 192. In an optional embodiment, the number of the limiting buckles 192 can be at least two, and each limiting buckle 192 is arranged at intervals on the bracket 100, and each limiting buckle 192 can limit the power supply assembly 400, so that the position of the power supply assembly 400 in the installation space 310 is not easy to change.

[0055] The power supply component 400 is provided with a second connecting terminal 410, and the second connecting terminal 410 and the first connecting terminal 210 of the lamp body 200 can be mechanically and electrically connected through the first through hole 130. Specifically, the second connecting terminal 410 can be coupled with the first connecting terminal 210 through the first through hole 130, or the first connecting terminal 210 can be coupled with the second connecting terminal 410 through the first through hole 130, so that the power supply component 400 is electrically connected to the lamp body 200 through the second connecting terminal 410 and the first connecting terminal 210, and the purpose of mechanically connecting the power supply component 400 and the lamp body 200 can also be achieved through the coupling of the second connecting terminal 410 and the first connecting terminal 210.

[0056] In the present application, since the power supply assembly 400 is arranged in the ceiling assembly connected to the lamp body 200, specifically in the installation space 310 surrounded by the mounting plate 300 and the bracket 100 of the ceiling assembly, and since the mounting plate 300 is detachably connected to the bracket 100, when replacing or repairing the power supply assembly 400, the mounting plate 300 can be removed from the bracket 100 to replace or repair the power supply assembly 400, that is, the present application does not need to open the lamp body 200, so this operation method is relatively simple and quick, and does not require professional personnel to operate, and thus the maintenance cost is low. Therefore, the ceiling assembly disclosed in the present application can solve the problem that the method of repairing lighting fixtures involved in the related art has relatively complicated operation and high maintenance cost.

[0057] In addition, the purpose of the integrated design of the bracket 100 and the power supply component 400 in the present application is to make the power supply component 400 and the second connection terminal 410 into a highly standardized module, that is, to make the ceiling component into a highly standardized module, which not only ensures a quick installation experience, but also only requires replacing the lamp body 200 when replacing or repairing the lighting fixture, which can reduce the user's replacement costs and will not cause corresponding waste of resources.

[0058] In an alternative embodiment, see Figure 1 , the edge of the mounting plate 300 is protruded with a bent support plate 320, and in the thickness direction of the ceiling assembly, the support plate 320 abuts against the bottom of the first limiting groove 140, and the support plate 320 can support part of the lamp body 200, that is, in the thickness direction of the ceiling assembly, the first protrusion 220 can overlap the support plate 320, and the support plate 320 abuts against the bottom of the first limiting groove 140, so that the support plate 320 and the bracket 100 can jointly support the lamp body 200, and in this process, the support plate 320 can provide the bracket 100 with a stronger load strength to stably set and support the lamp body 200. Of course, the edge of the mounting plate 300 may not be protruded with a bent support plate 320.

[0059] In an optional embodiment, the number of support plates 320 can be at least two, and each support plate 320 is spaced apart in the circumferential direction of the mounting plate 300. Correspondingly, the number of first limiting grooves 140 can also be at least two, and each first limiting groove 140 is spaced apart in the circumferential direction of the bracket 100. The number of first protrusions 220 can also be at least two, and each first protrusion 220 is spaced apart on the lamp body 200, and multiple support plates 320, multiple first limiting grooves 140 and multiple first protrusions 220 correspond one to one. At this time, multiple support plates 320 can provide the bracket 100 with stronger load strength to further stabilize the setting and support of the lamp body 200.

[0060] In an optional embodiment, the mounting plate 300 can be a metal mounting plate. In this case, the structural strength of the support plate 320 is relatively large, thereby providing a better support effect for the first protrusion 220. Moreover, since metal has better thermal conductivity and heat dissipation effects, the mounting plate 300 can also provide better heat dissipation for the power supply component 400.

[0061] In an optional embodiment, a fifth through hole 350 may be provided at the edge of the mounting plate 300 near the support plate 320, and a mounting hole 194 may be provided at the portion of the bracket 100 near the first limiting groove 140. In the specific process of connecting the mounting plate 300 and the bracket 100, one end of the fourth connecting member passes through the fifth through hole 350 and is connected to the mounting hole 194. The fourth connecting member may be a threaded connecting member, and the mounting hole 194 may be a threaded hole. The fourth connecting member is threadedly matched with the mounting hole 194 so that the mounting plate 300 and the bracket 100 can be detachably connected, and the fifth through hole 350 may be spaced apart from the fourth through hole 340 described above.

[0062] Since the fifth through hole 350 is arranged close to the support plate 320 and the mounting hole 194 is arranged close to the first limiting groove 140, when the mounting plate 300 and the bracket 100 are connected by the fourth connecting member, the support plate 320 can be made to fit more closely to the bottom of the first limiting groove 140, thereby improving the abutment stability between the support plate 320 and the bottom of the first limiting groove 140, thereby improving the stability of the supporting lamp body 200.

[0063] In an optional embodiment, during the process of installing the ceiling assembly on a mounting base (e.g., a ceiling), the mounting plate 300 is usually disposed toward the mounting base, and the spacing between the mounting plate 300 and the mounting base is small or even nonexistent, that is, the mounting plate 300 is usually in close contact with the mounting base. To prevent the ends of the second connecting member 620 and the fourth connecting member from protruding from the mounting plate 300 and resting against the mounting base, a second groove 360 ​​is provided on a side of the mounting plate 300 facing the mounting base, and the fourth through hole 340 and the fifth through hole 350 are provided at the bottom of the second groove 360. At this time, the ends of the second connecting member 620 and the fourth connecting member are both accommodated in the second groove 360, which can prevent the ends of the second connecting member 620 and the fourth connecting member from protruding from the mounting plate 300, that is, this arrangement will not affect the degree of fit between the mounting plate 300 and the mounting base.

[0064] In an alternative embodiment, see Figure 4 The bottom of the first limiting groove 140 may be provided with a first groove 142, the first groove 142 is connected to the first limiting groove 140, and at least a portion of the support plate 320 may be located in the first groove 142, that is, during the process of assembling the hanger 100 and the mounting plate 300, at least a portion of the support plate 320 may extend into the first groove 142 and abut against the bottom of the first groove 142.

[0065] At this time, in the thickness direction of the ceiling assembly, the support plate 320 occupies less space in the first limiting groove 140, that is, the support plate 320 protrudes less or even does not protrude from the bottom of the first limiting groove 140, so that during the assembly of the ceiling assembly and the lamp body 200, the support plate 320 is not easy to block the first protrusion 220 from entering the first limiting groove 140, that is, the present application can lift a less distance or even does not need to lift the lamp body 200 to achieve the purpose of hanging the first protrusion 220 on the support plate 320. Of course, the bottom of the first limiting groove 140 may not be provided with the first groove 142, and in this case, the support plate 320 can directly abut against the bottom of the first limiting groove 140.

[0066] In an alternative embodiment, see Figure 1The power supply assembly 400 may include a circuit board 420 and a power input terminal 430. The second connection terminal 410 and the power input terminal 430 are spaced apart on the circuit board 420, and the second connection terminal 410 and the power input terminal 430 are both electrically connected to the circuit board 420. The bracket 100 is also provided with a first limiting hole 150, and the power input terminal 430 is located in the first limiting hole 150, that is, the first limiting hole 150 can limit the power input terminal 430, thereby limiting the power supply assembly 400, so as to further ensure the stability of the power supply assembly 400 in the installation space 310. Of course, the bracket 100 may not be provided with the first limiting hole 150.

[0067] In an optional embodiment, the mounting plate 300 may be provided with a wire threading hole 330, and the bracket 100 may also be provided with a wire hiding hole 160 connected to the first limiting hole 150, so that the power input terminal 430 may be directly opposite the wire hiding hole 160, and the wire threading hole 330 is connected to the wire hiding hole 160. The ceiling assembly may also include a cable, which is a power supply cable. One end of the cable may pass through the wire threading hole 330, the wire hiding hole 160 and the first limiting hole 150 in sequence, and be electrically connected to the power input terminal 430 to supply power to the power supply assembly 400. The present application may place excess cables in the wire hiding hole 160 so that the excess cables do not occupy the space of the installation space 310, that is, the present application may design the spatial volume of the installation space 310 to be smaller, and thus the overall thickness of the ceiling assembly is thinner. Of course, the bracket 100 may also not be provided with the wire hiding hole 160. In this case, the excess cables may be placed in the installation space 310.

[0068] In an optional embodiment, in order to stably place the circuit board 420 in the installation space 310, the present application may use a third connecting member 630 to connect the circuit board 420 and the bracket 100, that is, connecting holes may be opened on the circuit board 420 and the bracket 100, one end of the third connecting member 630 passes through the connecting hole of the circuit board 420 and is connected to the connecting hole of the bracket 100, the third connecting member 630 may be a threaded connecting member, and the connecting hole of the bracket 100 may be a threaded hole, and the third connecting member 630 is threadedly matched with the connecting hole of the bracket 100 so that the circuit board 420 and the bracket 100 can be detachably connected.

[0069] Please refer to Figure 1 The ceiling assembly may further include an intelligent module 500, which may be a module for receiving WiFi signals, Bluetooth signals, etc. The intelligent module 500 may be used to realize intelligent light off, intelligent light on, and intelligent change of the light color of the lighting fixture. In an optional embodiment, the intelligent module 500 may be installed in the lamp body 200.

[0070] In another embodiment, the smart module 500 is installed on the rack 100, specifically, the smart module 500 is installed in the installation space 310, and the power supply assembly 400 may also include a third connection terminal 440, which is provided on the circuit board 420, and the third connection terminal 440 is plugged and matched with the smart module 500, so that the power supply assembly 400 provides working current to the smart module 500. In this embodiment, since the smart module 500 is installed in the installation space 310, it is convenient to repair or replace the smart module 500, that is, the user can open the installation board 300 during use, so as to replace the smart module 500, so as to achieve the purpose of expanding the function of the lighting fixture, and the third connection terminal 440 is an expansion interface, which can meet the needs of users to use different smart modules 500.

[0071] In further embodiments, please refer to Figure 5 and Figure 6 The bracket 100 is also provided with a second limiting hole 170, which connects the installation space 310 and the space between the bracket 100 and the lamp body 200. The smart module 500 is arranged in the second limiting hole 170. The second limiting hole 170 can limit the smart module 500, thereby ensuring the stability of the plug-in matching between the third connection terminal 440 and the smart module 500. Since the smart module 500 is arranged in the second limiting hole 170, the smart module 500 occupies less space in the installation space 310, which enables the present application to design the space volume of the installation space 310 to be smaller, and thus the overall thickness of the ceiling assembly is thinner. In this embodiment, when repairing or replacing the smart module 500, it is only necessary to quickly remove the lamp body 200 to repair or replace the smart module 500 without replacing the entire lamp body 200, which can reduce the cost of replacing the lamp for users.

[0072] In an optional embodiment, the rack 100 is further provided with a second limiting groove spaced apart from the second limiting hole 170, and a second opening 180 is provided on the side wall of the second limiting groove, and the second limiting groove is connected to the second limiting hole 170 through the second opening 180, and the third connection terminal 440 is located in the second limiting groove, that is, the third connection terminal 440 is limited in the second limiting groove, and one end of the third connection terminal 440 passes through the second opening 180 and is plugged and matched with the smart module 500. Since the third connection terminal 440 is limited in the second limiting groove, the third connection terminal 440 is not easy to shake at will during the process of plugging and matching the smart module 500 and the third connection terminal 440, which can improve the efficiency of plugging and matching the smart module 500 and the third connection terminal 440, and when installing the power supply assembly 400, the second limiting groove has a certain installation and positioning effect on the power supply assembly 400. Of course, the rack 100 may also not be provided with a second limiting groove.

[0073] In an alternative embodiment, see Figure 6 The side wall of the second limiting hole 170 and one of the smart modules 500 are protruded with a second protrusion 171, and the side wall of the second limiting hole 170 and the other of the smart modules 500 are protruded with a third protrusion 510, and the second protrusion 171 protrudes toward the side wall of the second limiting hole 170 and the other of the smart modules 500, and the third protrusion 510 protrudes toward the side wall of the second limiting hole 170 and one of the smart modules 500, and the third protrusion 510 is provided with a third limiting groove 511, and in the thickness direction of the ceiling assembly, the second protrusion 171 abuts against the inner wall of the third limiting groove 511.

[0074] Specifically, in the process of electrically connecting the smart module 500 and the third connection terminal 440, that is, in the process of plugging and matching the smart module 500 and the third connection terminal 440, the smart module 500 can slide into the second limiting hole 170, so that the second protrusion 171 can slide into the third limiting groove 511 of the third protrusion 510, and the sliding direction of the smart module 500 is consistent with the plug-in matching direction of the smart module 500 and the third connection terminal 440. After the second protrusion 171 slides into the third limiting groove 511, the second protrusion 171 can abut against the inner wall of the third limiting groove 511 in the thickness direction of the ceiling assembly to further ensure the setting stability of the smart module 500. Of course, the side wall of the second limiting hole 170 and the smart module 500 may not be provided with the second protrusion 171 and the third protrusion 510. In this case, the setting stability of the smart module 500 is ensured only by the plug-in matching force between the smart module 500 and the third connection terminal 440.

[0075] In addition, when replacing or repairing the smart module 500, the smart module 500 can be slid out of the second limiting hole 170 in a direction opposite to the direction in which the smart module 500 and the third connection terminal 440 are plugged and matched. In an optional embodiment, in order to facilitate the removal of the smart module 500, a third groove 530 can be opened on the smart module 500, and the third groove 530 is a reserved removal buckle position. The third groove 530 can facilitate the user to apply force to the smart module 500 to facilitate the replacement of the smart module 500.

[0076] In an alternative embodiment, see Figure 6, an elastic protrusion 520 is protruded on one of the side walls of the second limiting hole 170 and the side of the smart module 500 facing the third connection terminal 440, and a fourth limiting groove 172 is opened on the other of the side walls of the second limiting hole 170 and the side of the smart module 500 facing the third connection terminal 440, and in the matching direction of the smart module 500 and the third connection terminal 440, the elastic protrusion 520 and the fourth limiting groove 172 are elastically limited, that is, in the process of plugging and matching the smart module 500 and the third connection terminal 440, the elastic protrusion 520 can enter the fourth limiting groove 172, and elastically limit with the fourth limiting groove 172 in the plugging and matching direction of the smart module 500 and the third connection terminal 440, so as to prevent the accidental failure of the matching between the smart module 500 and the third connection terminal 440, that is, to prevent the smart module 500 from accidentally falling off. Of course, the present application may also not be provided with the elastic protrusion 520 and the fourth limiting groove 172.

[0077] In an optional embodiment, the number of elastic protrusions 520 and the number of fourth limiting grooves 172 can both be at least two, the elastic protrusions 520 can be arranged at intervals on the smart module 500, the fourth limiting grooves 172 can be arranged at intervals on the side wall of the second limiting hole 170, and the elastic protrusions 520 correspond to the fourth limiting grooves 172 one by one to further prevent accidental failure of the cooperation between the smart module 500 and the third connecting terminal 440.

[0078] In an alternative embodiment, see Figure 2 and Figure 3 The present application also discloses a lighting fixture, including a lamp body 200 and the ceiling assembly described above, the lamp body 200 is detachably connected to the bracket 100, a first protrusion 220 is protruded from the lamp body 200, and the first protrusion 220 is the first protrusion 220 described above, the first protrusion 220 can slide into the first limiting groove 140 along the circumference of the ceiling assembly, and abut against the side wall of the first limiting groove 140, and in the thickness direction of the ceiling assembly, the bottom of the first limiting groove 140 abuts against the first protrusion 220.

[0079] Specifically, please refer to Figure 4 and Figure 5The first limiting groove 140 is provided with a first opening 141, and the first opening 141 connects the first limiting groove 140 and the space between the bracket 100 and the lamp body 200. In the process of connecting the bracket 100 with the lamp body 200, the first protrusion 220 passes through the first opening 141 and slides into the first limiting groove 140 along the circumference of the bracket 100, and abuts against the side wall of the first limiting groove 140, and in the thickness direction of the lighting fixture, the first protrusion 220 is overlapped on the support plate 320 and the bottom of the first limiting groove 140 to achieve the purpose of hanging the lamp body 200 on the ceiling assembly; in the process of disassembling the lamp body 200 and the bracket 100, the lamp body 200 is rotated so that the first protrusion 220 slides toward the first opening 141 and slides out of the first limiting groove 140 to achieve the purpose of disassembling the lamp body 200 and the bracket 100.

[0080] In an optional embodiment, to prevent the first protrusion 220 from accidentally sliding out of the first limiting groove 140, please refer to Figure 2 and Figure 5 , a fourth protrusion 230 is protruded on the lamp body 200, and an anti-retraction buckle 191 is protruded on the bracket 100. When the first protrusion 220 slides into the first limiting groove 140, the fourth protrusion 230 will slide from one side of the anti-retraction buckle 191 to the other side of the anti-retraction buckle 191. At this time, the anti-retraction buckle 191 can prevent the fourth protrusion 230 from sliding to one side of the anti-retraction buckle 191 to avoid the first protrusion 220 accidentally sliding out of the first limiting groove 140. In the process of disassembling the lamp body 200 and the bracket 100, the operator needs to apply a large force to make the fourth protrusion 230 slide from the other side of the anti-retraction buckle 191 to one side of the anti-retraction buckle 191. At this time, the first protrusion 220 can smoothly slide out of the first limiting groove 140.

[0081] In an optional embodiment, the number of fourth protrusions 230 and the number of anti-retraction buckles 191 can both be at least two, the fourth protrusions 230 are arranged at intervals on the lamp body 200, the anti-retraction buckles 191 are arranged at intervals on the circumference of the bracket 100, and the fourth protrusions 230 correspond to the anti-retraction buckles 191 one by one to further prevent the first protrusion 220 from accidentally sliding out of the first limiting groove 140.

[0082] In an optional embodiment, the first connection terminal 210 and the second connection terminal 410 may both be annular connection terminals, and annular conductive parts may be attached to the inner wall of the first connection terminal 210 and the inner wall of the second connection terminal 410. In the process of electrically connecting the first connection terminal 210 and the second connection terminal 410, the first connection terminal 210 and the second connection terminal 410 are plugged into each other so that the annular conductive part on the inner wall of the first connection terminal 210 fits with the annular conductive part on the inner wall of the second connection terminal 410, thereby achieving the purpose of electrical connection.

[0083] In another embodiment, please refer to Figures 8 to 11 The power supply assembly 400 includes a circuit board 420, which is consistent with the circuit board 420 described above. The second connecting terminal 410 includes a first base 411 and a first ring member 412 and a second ring member 413 protruding from the first base 411 and arranged at intervals. The first ring member 412 is sleeved in the second ring member 413, and the first base 411 is arranged on the circuit board 420. The second connecting terminal 410 also includes a first spring clip 414 and a second spring clip 415 arranged at intervals and located between the first ring member 412 and the second ring member 413. One end of the first spring clip 414 and one end of the second spring clip 415 both pass through the first base 411 and are electrically connected to the circuit board 420.

[0084] The first connecting terminal 210 includes a second base 211 and a third ring-shaped member 212 protruding from the second base 211, and a first ring-shaped conductive member 213 is attached to the inner wall of the third ring-shaped member 212, and a second ring-shaped conductive member 214 is attached to the outer wall of the third ring-shaped member 212. When the first connecting terminal 210 is electromechanically connected to the second connecting terminal 410, that is, during the process of plugging and matching the first connecting terminal 210 and the second connecting terminal 410, the third ring-shaped member 212 will extend into the space between the first ring-shaped member 412 and the second ring-shaped member 413, so that the third ring-shaped member 212 is located in the space between the first ring-shaped member 412 and the second ring-shaped member 413, and at this time, the first spring piece 414 elastically abuts against the first ring-shaped conductive member 213 and is electrically connected, and the second spring piece 415 elastically abuts against the second ring-shaped conductive member 214 and is electrically connected.

[0085] It can be seen that the present application adopts the first spring clip 414 and the second spring clip 415 to achieve the purpose of electrically connecting the circuit board 420 with the first connecting terminal 210. Since the first spring clip 414 and the second spring clip 415 have a certain elastic force, this can ensure the reliability of the electrical connection, and by using the first spring clip 414 and the second spring clip 415 for conductivity, the amount of conductive material used in the second connecting terminal 410 can be reduced, which reduces costs. At the same time, when the bracket 100 and the lamp body 200 rotate relative to each other, the first spring clip 414 and the second spring clip 415 can always abut against the corresponding first annular conductive member 213 and the second annular conductive member 214, that is, it is ensured that the second connecting terminal 410 and the first connecting terminal 210 are always in a state of being electrically connected.

[0086] In an alternative embodiment, see Fig. 9 and Fig.11The first base 411 may include a tail cover 4113 and a base 4114, the tail cover 4113 and the base 4114 may be detachably connected via a buckle 4115, the first ring member 412 and the second ring member 413 may be arranged on the base 4114, and at least two slots 4116 may be opened on the tail cover 4113, one end of the first spring clip 414 and one end of the second spring clip 415 may pass through different slots 4116 and enter different jacks 423 of the circuit board 420, and be welded to the circuit board 420, so as to achieve the purpose of electrically connecting the first spring clip 414 and the second spring clip 415 to the circuit board 420.

[0087] In an alternative embodiment, see Fig.11 , the first spring piece 414 and the second spring piece 415 may both protrude with a fixed wall 4141 and a fifth protrusion 4151. When one end of the first spring piece 414 and one end of the second spring piece 415 pass through different slots 4116, the fixed wall 4141 may abut against the tail cover 4113, that is, the fixed wall 4141 may prevent most structures of the first spring piece 414 and the second spring piece 415 from passing through the slot 4116, and the fifth protrusion 4151 may enter the slot 4116 along with the first spring piece 414 and the second spring piece 415, and the fifth protrusion 4151 may abut against the side wall of the slot 4116 to prevent the first spring piece 414 and the second spring piece 415 from shaking at will in the slot 4116, that is, the fifth protrusion 4151 may limit the first spring piece 414 and the second spring piece 415 to ensure that one end of the first spring piece 414 and one end of the second spring piece 415 smoothly enter different sockets 423 of the circuit board 420.

[0088] In an alternative embodiment, see Figure 2 , Fig.10 and Fig.11 A third opening may be opened on the lamp body 200, and the third annular member 212 of the first connecting terminal 210 may extend out of the third opening and be electromechanically connected to the second connecting terminal 410. At this time, the second base 211 is located in the lamp body 200, and a fixing hole 2111 may be opened on the second base 211. The second base 211 may be arranged on the lamp body 200 through the fixing hole 2111 and the connecting member, and the ends of the first annular conductive member 213 and the second annular conductive member 214 away from the first spring clip 414 and the second spring clip 415 are both pins 215, and the pins 215 pass through the second base 211 and extend into the lamp body 200 to facilitate welding of leads inside the lamp body 200.

[0089] In an alternative embodiment, see Fig.10 and Fig.11The first spring piece 414 and the second spring piece 415 are both provided with an arc-shaped protrusion 416 at one end away from the first base 411. The arc-shaped protrusion 416 of the first spring piece 414 can abut against the first annular conductive member 213, and the arc-shaped protrusion 416 of the second spring piece 415 can abut against the second annular conductive member 214. When the hanger 100 and the lamp body 200 rotate relative to each other, the arc-shaped protrusion 416 can reduce the rotational friction and ensure that the abutting contact between the first spring piece 414 and the first annular conductive member 213 and the second spring piece 415 and the second annular conductive member 214 are relatively stable. Of course, the first spring piece 414 and the second spring piece 415 can also be provided with no arc-shaped protrusion 416 at one end away from the first base 411.

[0090] In an alternative embodiment, see Fig.11 The first elastic sheet 414 and the second elastic sheet 415 are both provided with a guide surface 417 at one end away from the first base 411. The guide surface 417 may be a guide flange. During the plug-in matching process of the first connection terminal 210 and the second connection terminal 410, the end of the third ring member 212 may be guided and matched with the guide surface 417, so that the first elastic sheet 414 and the second elastic sheet 415 can smoothly and quickly elastically abut against the corresponding first annular conductive member 213 and the second annular conductive member 214. Of course, the first elastic sheet 414 and the second elastic sheet 415 may not be provided with a guide surface 417 at one end away from the first base 411.

[0091] In an alternative embodiment, see Fig.10 and Fig.11 The first spring piece 414 and the second spring piece 415 are both provided with a clamping portion 418 protruding from one end away from the first base 411, and the first ring member 412 and the second ring member 413 are both provided with a clamping groove 4131, and the clamping portion 418 is clamped with the clamping groove 4131. When the hanger 100 and the lamp body 200 rotate relatively, the clamping portion 418 and the clamping groove 4131 can prevent the first spring piece 414 and the second spring piece 415 from being easily twisted and deformed due to the rotational friction force, and the clamping groove 4131 can prevent the first spring piece 414 and the second spring piece 415 from extending too much from the clamping groove 4131 at one end away from the first base 411. Of course, the first spring piece 414 and the second spring piece 415 may not be provided with a clamping portion 418 at one end away from the first base 411, and the first ring member 412 and the second ring member 413 may not be provided with a clamping groove 4131.

[0092] In an alternative embodiment, see Figure 1 and Fig. 9The lighting fixture may further include a first connector 610, a first connecting hole 4111 is provided on the first base 411, a second through hole 421 is provided on the circuit board 420, one end of the first connector 610 passes through the second through hole 421 and is connected to the first connecting hole 4111, so that the second connecting terminal 410 is provided on the circuit board 420. In an optional embodiment, the first connector 610 may be a threaded connector, the first connecting hole 4111 may be a threaded hole, and the first connector 610 is threadedly matched with the first connecting hole 4111, so that the second connecting terminal 410 is detachably connected to the circuit board 420.

[0093] In this embodiment, the other end of the first connector 610 protrudes from the circuit board 420 and has a preset distance from the mounting plate 300. When the mounting plate 300 is deformed by an unexpected force, the mounting plate 300 can be deformed in the space between the first connector 610 and the mounting plate 300, thereby avoiding squeezing the first connector 610 and further squeezing the circuit board 420. That is, by maintaining the distance, it is possible to prevent the mounting plate 300 from being deformed by an external force, causing a short circuit fault in the circuit board 420. Of course, there may not be a preset distance between the other end of the first connector 610 and the mounting plate 300, that is, the other end of the first connector 610 is always in contact with the mounting plate 300.

[0094] In an alternative embodiment, see Figure 1 and Fig. 9 , a positioning column 4112 is protruded from one side of the first base 411 away from the first annular member 412 and the second annular member 413, and a positioning hole 422 is provided on the circuit board 420. The positioning column 4112 can be positioned and matched with the positioning hole 422. The positioning column 4112 and the positioning hole 422 can facilitate positioning the second connection terminal 410 on the circuit board 420, and connect the second connection terminal 410 and the circuit board 420 through the first connecting member 610. Of course, the positioning column 4112 may not be protruded from the first base 411, and the positioning hole 422 may not be provided on the circuit board 420.

[0095] In an alternative embodiment, see Fig.11 The first spring sheet 414 and the second spring sheet 415 are both provided with a third through hole 419, and the third through hole 419 can facilitate the elastic deformation of the first spring sheet 414 and the second spring sheet 415, so that the first spring sheet 414 and the second spring sheet 415 can be more easily elastically abutted against the corresponding first annular conductive member 213 and the second annular conductive member 214. Of course, the first spring sheet 414 and the second spring sheet 415 may not be provided with the third through hole 419.

[0096] In an optional embodiment, the number of the third through holes 419 may be at least two, and the third through holes 419 are arranged at intervals on the first elastic sheet 414 or the second elastic sheet 415 to make it easier for the first elastic sheet 414 and the second elastic sheet 415 to detect elastic deformation.
