[0036] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means more than two unless otherwise specifically defined.

[0037] As described in the background art, a lamp refers to an appliance that can transmit light, distribute, and change the light distribution of a light source, including all components required for fixing and protecting the light source except the light source itself, as well as the line accessories necessary for connecting to a power source. In the related art, a lamp includes a lamp body and a mounting plate. The mounting plate is installed on the ceiling, and the lamp body is installed on the mounting plate by using a metal elastic sheet clamped between the mounting plate and the lamp body. The metal elastic sheet needs to be mechanically connected to the fixing holes on the mounting plate through a wing nut or a bolt, and the height of the metal elastic sheet is adjusted to adapt to ceilings of different thicknesses. Although the above assembly method can connect the lamp body and the mounting plate, the assembly process is relatively complex and time-consuming and laborious.

[0038] Referring to Figures 1 to 6 , to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a lamp, which includes a mounting plate 100 and a lamp body 200. The mounting plate 100 is used for being assembled in the area to be installed of the lamp, and the lamp body 200 can rotate relative to the mounting plate 100; one of the mounting plate 100 and the lamp body 200 is provided with a plugging structure 130, and the other is provided with a slot 221. The lamp body 200 is fixed to the mounting plate 100 by rotating relative to the mounting plate 100 so that the plugging structure 130 is inserted into the slot 221.

[0039] In the embodiment of the present application, the lamp is a downlight. It can be understood that the lamp can also be a ceiling lamp, a spotlight or other lamps. The mounting plate 100 is fixedly installed on the ceiling, and the ceiling forms the installation area for the lamp. It can be understood that the mounting plate 100 can also be fixedly installed on the installation areas of other lamps, such as walls, furniture or beams. The lamp body 200 is coaxially arranged with the mounting plate 100 and can rotate relative to the mounting plate 100 around its own axis. It can be understood that the lamp body 200 can also be eccentrically arranged with the mounting plate 100 and can rotate relative to the mounting plate 100 around its own axis.

[0040] When assembling the mounting plate 100 and the lamp body 200, first install the mounting plate 100 on the installation area of the lamp, then align the plugging structure 130 with the slot 221, and drive the lamp body 200 to rotate relative to the mounting plate 100. During the rotation, the plugging structure 130 will smoothly insert into the slot 221, thus realizing the rapid assembly of the lamp body 200 and the mounting plate 100.

[0041] Compared with the traditional assembly method using metal elastic pieces, this rotation plugging method of the present application not only greatly reduces the assembly steps, but also does not require special tools for assembly, saving assembly time and labor costs and improving the assembly efficiency. At the same time, it also makes the connection between the mounting plate 100 and the lamp body 200 tighter and more stable. This connection method is not easy to loosen due to external vibration or long-term use, which can better ensure the stability of the lamp during use and reduce the risk of the lamp falling due to unstable connection. In addition, when the lamp fails and needs to be repaired or replaced, just rotate and pull out the lamp body 200 relative to the mounting plate 100, and the lamp body 200 can be conveniently operated, which is convenient for later maintenance and servicing.

[0042] In addition, the cooperating plugging structure 130 and slot 221 not only eliminate the space occupied by the metal elastic piece, enabling the volume of the lamp body 200 to be appropriately expanded and the cable routing path to be more reasonable. At the same time, it is no longer dependent on the thickness of the ceiling. For ceilings or installation areas of other lamps with different thicknesses, as long as it is ensured that the mounting plate 100 can be fixed on them, the lamp body 200 can be installed by the same rotation plugging method, which has stronger versatility and adaptability.

[0043] To fixedly install the mounting plate 100 on the area to be installed of the lamp, threaded holes are provided in the area to be installed of the lamp. A threaded member 300 (such as a screw or a bolt) is threadedly screwed into the threaded hole, and at the same time, the head of the threaded member 300 extends downward. A connecting arc hole 110 is provided on the mounting plate 100. The connecting arc hole 110 is arranged around the axis of the mounting plate 100. The connecting arc hole 110 includes a penetrating hole section 111 and a limiting hole section 112 that communicate with each other. The aperture of the penetrating hole section 111 is larger than that of the limiting hole section 112 and larger than the diameter of the head of the threaded member 300. The aperture of the limiting hole section 112 is smaller than the diameter of the head of the threaded member 300 and larger than the diameter of the main body part of the threaded member 300.

[0044] When the mounting plate 100 is installed on the area to be installed of the lamp, first, the threaded member 300 is threadedly screwed into the threaded hole. At this time, the head of the threaded member 300 extends downward. Then, the penetrating hole section 111 is aligned with the head of the threaded member 300, and the mounting plate 100 is driven to move towards the ceiling until the head of the threaded member 300 passes through the penetrating hole section 111. Next, the mounting plate 100 is driven to rotate so that the main body part of the threaded portion is inserted into the limiting hole section 112. At this time, the head of the threaded member 300 will be located on the side of the mounting plate 100 away from the area to be installed of the lamp and will be restricted by the hole wall of the limiting hole section 112 from moving towards the area to be installed of the lamp.

[0045] To strengthen the installation strength of the mounting plate 100 installed on the area to be installed of the lamp, the number of the threaded members 300 is two. The two threaded members 300 are arranged at intervals around the axis of the mounting plate 100. The number of the connecting arc holes 110 is also two. The two connecting arc holes 110 are respectively arranged in one-to-one correspondence with the two threaded members 300.

[0046] Refer to Figures 1 to 6 , in an embodiment, the mounting plate 100 is provided with a through hole 120. A part of the structure of the lamp body 200 passes through the through hole 120, and a plugging structure 130 or a slot 221 is arranged on the hole wall of the through hole 120.

[0047] In this embodiment, the through hole 120 is coaxially arranged with the mounting plate 100. The above structural design not only helps to shorten the distance between the mounting plate 100 and the lamp body 200 and makes the space occupied by the lamp in the vertical direction smaller, so that the overall lamp realizes a compact design. At the same time, it also enables the mounting plate 100 and the lamp body 200 to achieve multi-dimensional connection, limits the lamp body 200 in different dimensions, effectively enhances the connection stability between the lamp body 200 and the mounting plate 100, and reduces the risk of the lamp shaking during use.

[0048] Refer to Figures 1 to 6 , in an embodiment, the plugging structure 130 is arranged on the hole wall of the through hole 120, and the slot 221 is arranged on the lamp body 200.

[0049] In this embodiment, the plug-in structure 130 is a plug-in strip made by stamping and bending. It can be understood that the plug-in structure 130 can also be made by integral molding or welding.

[0050] During installation, align the slot 221 of the lamp body 200 with the plug-in structure 130 on the hole wall of the through hole 120, and then rotate the lamp body 200 by 15° to 20° to complete the installation. Since the plug-in structure 130 is fixed on the hole wall of the through hole 120, its position is relatively stable and easy to locate. Installers can assemble the lamp body 200 and the mounting plate 100 more conveniently and accurately, with more convenient operation and improved installation efficiency.

[0051] The hole wall of the through hole 120 is relatively thick and strong, which can provide more stable support for the plug-in structure 130. By setting the plug-in structure 130 on the hole wall, the plug-in structure 130 can better cooperate with the slot 221, and when bearing the weight and external force of the lamp body 200, the force can be more evenly dispersed, thereby enhancing the connection stability between the lamp body 200 and the mounting plate 100 and reducing the possibility of the lamp shaking or falling due to loose connection.

[0052] In addition, the above method also makes the plug-in structure 130 on the mounting plate 100 have a certain universality. For lamp bodies 200 of different shapes and sizes, as long as the slots 221 can be reasonably set on their surfaces, they can be fitted and installed with the mounting plate 100 of the same specification. This provides greater flexibility for the design and production of lamps, facilitating manufacturers to introduce diversified lamp body 200 styles according to market demands without frequently changing the design of the mounting plate 100.

[0053] Refer to Figures 1 to 7 , in an embodiment, the lamp body 200 includes a lamp body 210 and a plug-in body 220. A part of the structure of the lamp body 210 passes through the through hole 120, and the plug-in body 220 is arranged on the outer peripheral surface of the lamp body 210. The slot 221 is arranged on the surface of the plug-in body 220 away from the lamp body 210. The slot 221 has a first slot wall 2211, and the first slot wall 2211 is provided with an opening 2211a penetrating to the outside of the slot 221. The lamp body 200 is installed on the mounting plate 100 by inserting the plug-in structure 130 through the opening 2211a into the slot 221.

[0054] In this embodiment, the lamp body 210 includes a driving box 211 and a driving component. A part of the structure of the driving box 211 passes through the through hole 120. The plug-in body 220 is arranged on the outer peripheral surface of the driving box 211 and is an integrally formed part with the driving box 211. At the same time, the driving component is fixedly installed in the driving box 211 and includes a power input circuit, a controller, a converter, a current detection resistor, a protection circuit, and a communication interface circuit. The slot 221 is recessed from the surface of the plug-in body 220 away from the lamp body 210 towards the inside of the lamp body 210, and the opening 2211a completely covers the first slot wall 2211. It can be understood that the opening 2211a may also only cover a part of the structure of the first slot wall 2211.

[0055] The arranged plug-in body 220 avoids directly arranging the slot 221 on the lamp body 210, reduces the influence on the internal space and structure of the lamp body 210 caused by arranging the slot 221, and is beneficial to maintaining the integrity and aesthetics of the lamp body 210. At the same time, for different types or specifications of lamps, as long as the sizes of the plug-in structure 130 and the slot 221 of the plug-in body 220 are ensured to match, the assembly can be completed. This provides greater flexibility for the design and production of lamps, facilitating the manufacturer to launch diversified lamp body 210 styles according to market demands without frequently changing the design of the plug-in body 220.

[0056] Refer to Figures 1 to 7 , in an embodiment, the slot 221 further has a second slot wall 2212 and a third slot wall 2213 which are oppositely arranged. Both the second slot wall 2212 and the third slot wall 2213 are adjacent to the first slot wall 2211. The second slot wall 2212 is provided with an avoidance opening 2212a penetrating to the outside of the slot 221. The plug-in structure 130 is inserted into the slot 221 through the opening 2211a and the avoidance opening 2212a. The plug-in structure 130 has a supporting surface 131. After the plug-in structure 130 is inserted into the slot 221, the plug-in structure 130 contacts the third slot wall 2213 through the supporting surface 131 to apply a supporting force to the plug-in body 220.

[0057] In this embodiment, both the second slot wall 2212 and the third slot wall 2213 are perpendicular to the first slot wall 2211. The avoidance opening 2212a completely covers the second slot wall 2212. It can be understood that the avoidance opening 2212a may also only cover a part of the structure of the second slot wall 2212.

[0058] The existence of the avoidance opening 2212a provides more path options and angle adjustment space for the insertion of the plug-in structure 130. During assembly, the plug-in structure 130 can be inserted into the slot 221 in a more flexible manner through the opening 2211a and the avoidance opening 2212a, reducing the alignment accuracy requirements for the plug-in structure 130 and the slot 221 during the assembly process and lowering the installation difficulty. Especially in some cases where the space is limited or the installation position is not convenient for operation, the assembly of the lamp body 200 and the mounting plate 100 can be completed more conveniently.

[0059] After the plug-in structure 130 is inserted into the slot 221, the support surface 131 contacts the third groove wall 2213 and provides a supporting force, which helps to disperse the weight of the lamp body 200 and makes the force on the lamp body 200 more uniform. At the same time, the second groove wall 2212 and the third groove wall 2213 are adjacent to the first groove wall 2211 and jointly form a relatively enclosed slot 221 space, which limits and supports the plug-in structure 130 from multiple directions, effectively improving the connection stability between the lamp body 200 and the mounting plate 100 and reducing the possibility of the lamp body 200 shaking or loosening during use.

[0060] Refer to Figures 1 to 7 , in an embodiment, the slot 221 further has a fourth groove wall 2214, and the fourth groove wall 2214 is disposed opposite to the first groove wall 2211 and is used to prevent the plug-in structure 130 located in the slot 221 from moving in a direction away from the first groove wall 2211.

[0061] In this embodiment, the fourth groove wall 2214 is perpendicular to the second groove wall 2212 and perpendicular to the third groove wall 2213. The plug-in body 220 is an L-shaped strip, wherein the third groove wall 2213 is the long side of the plug-in body 220, and the fourth groove wall 2214 is the short side of the plug-in body 220. Figure 7 The dashed lines in

[0062] The provided fourth groove wall 2214 can not only effectively prevent the plug-in structure 130 located in the slot 221 from moving out of the slot 221 in a direction away from the opening 2211a, thereby ensuring that the plug-in structure 130 can stay firmly in the slot 221 and guaranteeing the safety and stability of the lamp during use. At the same time, it also provides a clear positioning reference for the plug-in structure 130, enabling the installer to insert the plug-in structure 130 into the slot 221 more accurately and ensuring its proper installation, improving the installation efficiency and accuracy.

[0063] Refer to Figures 1 to 7, in one embodiment, a blocking structure 230 is provided on the third groove wall 2213. The blocking structure 230 protrudes towards the second groove wall 2212 and is used to block the insertion structure 130 located in the insertion slot 221 from detaching from the insertion slot 221 through the opening 2211a.

[0064] In this embodiment, the blocking structure 230 is an elastic structure, such as a plastic part or a rubber part, and is an integrally formed part with the insertion body 220; it can be understood that the blocking structure 230 can also be fixedly installed on the insertion body 220 by means of gluing.

[0065] The provided blocking structure 230 can effectively block the accidental detachment of the insertion structure 130 from the opening 2211a after the insertion structure 130 is inserted into the insertion slot 221, ensuring the safety and stability of the lamp during use. At the same time, the blocking structure 230 and the fourth groove wall 2214 cooperate with each other to form a bilateral constraint on the insertion structure 130 from two opposite directions. This constraint mechanism greatly limits the displacement of the insertion structure 130 in the insertion slot 221, making its fixation in the insertion slot 221 more stable and further enhancing the stability of the connection between the lamp board and the mounting board 100.

[0066] Refer to Figure 3 and Figure 5 , in one embodiment, the mounting board 100 has a front surface 140 and a back surface 150 which are oppositely arranged, and the insertion structure 130 protrudes towards the side of the back surface 150 away from the front surface 140.

[0067] In this embodiment, after the mounting board 100 is arranged on the area to be installed of the lamp, the back surface 150 is located on the side of the front surface 140 close to the area to be installed of the lamp, and the insertion structure 130 protrudes towards the area to be installed of the lamp. The insertion structure 130 protruding towards the back surface 150 of the mounting board 100 keeps the front surface 140 of the mounting board 100 flat and does not affect the overall aesthetics due to the protruding insertion structure 130. At the same time, the mounting board 100 plays a certain protective role for the insertion structure 130 arranged on the back surface 150, reducing the possibility of damage to the insertion structure 130 due to collision and friction during daily use, prolonging the service life of the insertion structure 130, and thus improving the overall reliability of the lamp.

[0068] Refer to Figures 1 to 7 , in one embodiment, the blocking structure 230 has a blocking surface 231. After the insertion structure 130 is inserted into the insertion slot 221, the supporting surface 131 is located on the side of the blocking surface 231 away from the back surface 150 to block the insertion structure 130 located in the insertion slot 221 from detaching from the insertion slot 221 through the opening 2211a.

[0069] In this embodiment, after the mounting plate 100 is disposed on the area to be installed of the lamp, the third groove wall 2213 is located on the side of the second groove wall 2212 close to the area to be installed of the lamp. When the lamp is subjected to vibration, shaking or external pulling force, the supporting surface 131 is blocked by the blocking surface 231, restricting the plugging structure 130 from disengaging from the slot 221 through the opening 2211a, enhancing the connection stability between the lamp body 200 and the mounting plate 100, and reducing the risk of accidental dropping of the lamp.

[0070] Referring to Figures 1 to 6 , in one embodiment, the plugging structure 130 has a first guiding inclined surface 132 and a second guiding inclined surface 133 which are oppositely arranged. After the plugging structure 130 is inserted into the slot 221, the fourth groove wall 2214, the first guiding inclined surface 132, the second guiding inclined surface 133 and the blocking structure 230 are arranged in sequence; the first guiding inclined surface 132 inclines towards the second guiding inclined surface 133 from the front surface 140 to the back surface 150, and the second guiding inclined surface 133 inclines towards the first guiding inclined surface 132 from the front surface 140 to the back surface 150.

[0071] In this embodiment, the first guiding inclined surface 132 and the second guiding inclined surface 133 intersect and have the same inclination angle. It can be understood that the inclination angles of the first guiding inclined surface 132 and the second guiding inclined surface 133 may also be different.

[0072] During the process of the plugging structure 130 being inserted into the slot 221, the first guiding inclined surface 132 first contacts the blocking structure 230. With the continuous rotation of the lamp body 200, the first guiding inclined surface 132 smoothly crosses the blocking structure 230 by virtue of its inclined design, enters the interior of the slot 221, and finally corresponds precisely to the fourth groove wall 2214. Then, the continuously rotating lamp body 200 drives the second guiding inclined surface 133 to cross the blocking structure 230, enter the slot 221, and make it located on the side of the blocking structure 230 close to the fourth groove wall 2214.

[0073] During the process of the plugging structure 130 disengaging from the slot 221, the second guiding inclined surface 133 first contacts the blocking structure 230. With the continuous rotation of the lamp body 200, the second guiding inclined surface 133 smoothly crosses the blocking structure 230 by virtue of its inclined design, enters the outside of the slot 221. Then, the continuously rotating lamp body 200 drives the first guiding inclined surface 132 to cross the blocking structure 230 and move outside the slot 221.

[0074] The first guiding inclined surface 132 provided guides and a leading function for the insertion structure 130 to be inserted into the slot 221, helping the insertion structure 130 to smoothly pass through the blocking structure 230 and be inserted into the slot 221; the second guiding inclined surface 133 provided a guiding function for the insertion structure 130 to disengage from the slot 221, helping the insertion structure 130 to smoothly disengage from the slot 221 by passing through the blocking structure 230 and the opening 2211a in sequence. At the same time, during the process of the insertion structure 130 inserting into or disengaging from the slot 221, the first guiding inclined surface 132 and the second guiding inclined surface 133 provided can also effectively reduce the friction and collision between the insertion structure 130 and the blocking structure 230, reduce the wear degree of the first guiding inclined surface 132, the second guiding inclined surface 133 and the blocking structure 230, and extend the service life of the insertion structure 130 and the blocking structure 230.

[0075] Referring to Figures 1 to 7 , in an implementation manner, the blocking structure 230 has a third guiding inclined surface 232 and a fourth guiding inclined surface 233 arranged oppositely, and the fourth groove wall 2214, the third guiding inclined surface 232, the fourth guiding inclined surface 233 and the first groove wall 2211 are arranged in sequence; the third guiding inclined surface 232 inclines from the third groove wall 2213 to the second groove wall 2212 towards the fourth guiding inclined surface 233, and the fourth guiding inclined surface 233 inclines from the third groove wall 2213 to the second groove wall 2212 towards the third guiding inclined surface 232.

[0076] In this implementation manner, the blocking surface 231 is located between the third guiding inclined surface 232 and the fourth guiding inclined surface 233. At the same time, the third guiding inclined surface 232 and the fourth guiding inclined surface 233 intersect and have the same inclination angle. It can be understood that the inclination angles of the third guiding inclined surface 232 and the fourth guiding inclined surface 233 can also be different. After the insertion structure 130 is inserted into the slot 221, the fourth groove wall 2214, the first guiding inclined surface 132, the second guiding inclined surface 133, the third guiding inclined surface 232, the fourth guiding inclined surface 233 and the first groove wall 2211 are arranged in sequence, wherein the inclination angle of the third guiding inclined surface 232 is different from that of the first guiding inclined surface 132.

[0077] During the process of the insertion structure 130 inserting into the slot 221, the first guiding inclined surface 132 first contacts the fourth guiding inclined surface 233. As the lamp body 200 continues to rotate, under the guidance of the fourth guiding inclined surface 233, the first guiding inclined surface 132 smoothly crosses the blocking structure 230, enters the inside of the slot 221, and finally corresponds precisely to the fourth groove wall 2214. Then, the continuously rotating lamp body 200 drives the second guiding inclined surface 133 to cross the blocking structure 230, enter the slot 221, and make it located on the side of the blocking structure 230 close to the fourth groove wall 2214.

[0078] During the process of the plug-in structure 130 disengaging from the slot 221, the second guiding inclined surface 133 first contacts the third guiding inclined surface 232. As the lamp body 200 continues to rotate, the second guiding inclined surface 133 is guided by the third guiding inclined surface 232 and successfully crosses the blocking structure 230 and enters the outside of the slot 221. Then, the continuously rotating lamp body 200 drives the second guiding inclined surface 133 to cross the blocking structure 230 and move outside the slot 221.

[0079] The provided third guiding inclined surface 232 provides a guiding function for the plug-in structure 130 to disengage from the slot 221, helping the plug-in structure 130 to successfully disengage from the slot 221 through the blocking structure 230 and the opening 2211a in sequence; the provided fourth guiding inclined surface 233 provides a guiding and leading function for the plug-in structure 130 to be inserted into the slot 221, helping the plug-in structure 130 to be successfully inserted into the slot 221 through the blocking structure 230. At the same time, during the process of the plug-in structure 130 being inserted into or disengaging from the slot 221, the provided third guiding inclined surface 232 and fourth guiding inclined surface 233 can also effectively reduce the friction and collision between the plug-in structure 130 and the blocking structure 230, reduce the wear degree of the third guiding inclined surface 232, the fourth guiding inclined surface 233 and the plug-in structure 130, and extend the service life of the plug-in structure 130 and the blocking structure 230.

[0080] Refer to Figure 5 , in an embodiment, the mounting plate 100 is provided with a marking structure 160, and the hole wall of the through hole 120 is provided with an avoidance hole 170. The marking structure 160 and the avoidance hole 170 are respectively arranged on opposite sides of the plug-in structure 130.

[0081] In this embodiment, the avoidance hole 170 is a through hole penetrating the mounting plate 100, and the marking structure 160 can be a marking point, a marking line, a marking pattern or a marking symbol; the avoidance hole 170 is arranged on the side of the first guiding inclined surface 132 away from the second guiding inclined surface 133, and the marking structure 160 is arranged on the side of the second guiding inclined surface 133 away from the first guiding inclined surface 132.

[0082] The marking structure 160 can not only be used as a reference mark during installation, facilitating the user to quickly and accurately position and install the lamp body 200 and the mounting plate 100, improving the installation efficiency and accuracy. At the same time, it can also be used as a positioning reference during the stamping and bending process; during the design and operation of the stamping die, by aligning the marking structure 160, the position and angle of the plug-in structure 130 can be more accurately determined, thereby improving the bending precision and making the size and shape of the plug-in structure 130 more in line with the design requirements.

[0083] The avoidance hole 170 provides space for possible deformation or displacement of the insertion structure 130 during the stamping and bending process, avoiding interference between the insertion structure 130 and the wall of the through hole 120, ensuring the normal forming and use of the insertion structure 130; at the same time, it also reduces the occurrence of component damage or improper installation caused by interference.

[0084] Referring to Figure 5 , in one embodiment, the marking structure 160 is a marking hole, and the marking hole is arranged on the wall of the through hole 120.

[0085] In this embodiment, the marking hole is a through hole penetrating the mounting plate 100. It is relatively easy to machine the marking hole on the wall of the through hole 120, which can be carried out simultaneously with the machining of the through hole 120 without additional complex processes or special tools, reducing the machining cost and difficulty and being beneficial to improving production efficiency. At the same time, setting the marking structure 160 on the wall of the through hole 120 does not occupy other space of the mounting plate 100 additionally, making the layout of the mounting plate 100 more compact and reasonable, and realizing a good integration of the marking function and other structural functions within the limited space. In addition, as a solid structure, the marking hole is clearer and more prominent compared with some surface marking methods such as spraying marks, and is not easily disappeared due to factors such as wear and corrosion, and can maintain its marking function for a long time, providing a stable and reliable identifier for subsequent installation, maintenance and other work.

[0086] Referring to Figure 1 and Figure 3 , in one embodiment, the number of the insertion structures 130 is two, and the two insertion structures 130 are arranged at intervals along the circumferential direction of the wall of the through hole 120; the numbers of the insertion bodies 220 and the slots 221 are also both two, and the two insertion structures 130 are respectively arranged in one-to-one correspondence with the two insertion bodies 220 and the two slots 221.

[0087] The cooperation of the two insertion structures 130 with the corresponding insertion bodies 220 and slots 221 can provide a more uniform force distribution. Compared with a single insertion structure 130, it can effectively disperse the force borne by the connection part, reducing the possibility of connection loosening or damage caused by excessive single-point force, thereby enhancing the stability and reliability of the overall connection.

[0088] At the same time, even if one of the insertion structures 130 fails or is damaged, the other insertion structure 130 can still maintain the connection to a certain extent, providing temporary support and positioning functions, increasing the fault tolerance of the entire lamp, improving the reliability and safety of the lamp, and providing a buffer time for repairing and replacing components.

[0089] Referring to Figure 1 and Figure 8, in one embodiment, at least one UL spring 180 is provided on the back surface 150 of the mounting plate 100. In this embodiment, two UL springs 180 (the full English name of UL is Underwriters Laboratories, and the Chinese name is Underwriters Laboratories) are mounted on the back surface 150 of the mounting plate 100, and the two UL springs 180 are symmetrically arranged with the axis of the mounting plate 100 as the center.

[0090] Referring to Figure 8 , in one embodiment, the lamp body 210 further includes a light-transmitting plate 212, a light-shielding ring 213, a light guide plate 214, a reflective paper 216, an FPC light source board 215 (the full English name of FPC is Flexible Printed Circuit, and the Chinese name is Flexible Printed Circuit Board), a reflective paper 216, a face ring 217, and a foam 218. Among them, the light-transmitting plate 212, the light-shielding ring 213, the light guide plate 214, the reflective paper 216, the FPC light source board 215, the reflective paper, the foam 218, and the drive box 211 are all arranged on the face ring 217.

[0091] In summary, implementing the lamp provided in this embodiment has at least the following beneficial technical effects: Compared with the traditional assembly method using metal shrapnel, this rotary plug-in method of the present application not only greatly reduces the assembly steps, but also does not require special tools for assembly, saving assembly time and labor costs, and improving the assembly efficiency. At the same time, it also makes the connection between the mounting plate 100 and the lamp body 200 more tight and stable. This connection method is not easy to loosen due to external vibration or long-term use, and can better ensure the stability of the lamp during use, reducing the risk of the lamp falling due to unstable connection. In addition, when the lamp fails and needs to be repaired or replaced, simply rotate and pull out the lamp body 200 relative to the mounting plate 100, and the lamp body 200 can be easily operated, facilitating later maintenance and repair. Moreover, the present application directly forms a plurality of plug-in structures 130 by folding inside the mounting plate 100, with a simple structure and no need to additionally add other parts or components for installation with the lamp body 200.

[0092] In addition, the cooperating plug-in structure 130 and the slot 221 not only eliminate the space occupied by the metal shrapnel, enabling the volume of the lamp body 200 to be appropriately expanded and the cable routing path to be more reasonable. At the same time, it is no longer dependent on the thickness of the ceiling. For ceilings of different thicknesses or other areas where the lamp needs to be installed, as long as the mounting plate 100 can be fixed on it, the lamp body 200 can be installed by the same rotary plug-in method, with stronger versatility and adaptability.

[0093] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
