DETAILED DESCRIPTION

[0056] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0057] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0058] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0059] In order to solve the problem that the height and lighting direction of the flat panel lamp device in the prior art are difficult to adjust, the present invention provides a flat panel lamp device.

[0060] like Figures 1 to 28As shown, the flat lamp device includes a lamp body 10, a transition connecting plate 20 and an adjustment structure. The lamp body 10 includes a frame 11, which is located on the light-emitting side of the lamp body 10, and has a first connecting member; the transition connecting plate 20 is located on the backlight side of the lamp body 10, and the transition connecting plate 20 and the lamp body 10 and at least one of the transition connecting plate 20 and the base 30 to be installed are detachably connected; the adjustment structure is arranged on the transition connecting plate 20, and the distance between the lamp body 10 and the base 30 to be installed and the inclination angle of the lamp body 10 relative to the base 30 to be installed are adjusted by the adjustment structure.

[0061] By setting a detachable connection between the transition connecting plate 20 and the lamp body 10 and between the transition connecting plate 20 and the base 30 to be installed, the transition connecting plate 20 and the lamp body 10 are detachably connected, or the transition connecting plate 20 and the base 30 to be installed are detachably connected, or both are detachably connected. Through this detachable connection method, the installation and disassembly of the lamp body 10 are more convenient, which is conducive to reducing the difficulty of disassembly and improving the efficiency of disassembly. In addition, by setting an adjustment structure, the adjustment structure can adjust the distance between the lamp body 10 and the base 30 to be installed, so that the height of the lamp body 10 can be adjusted to achieve different lighting effects; at the same time, the adjustment structure can also adjust the inclination angle of the lamp body 10 relative to the base 30 to be installed, so as to adjust the light-emitting direction and angle of the lamp body 10, so that the flat lamp device can adapt to different application scenarios, expand the versatility, and improve the user experience.

[0062] It should be noted that the lamp body 10 is an integrated lamp body, which is a whole and can be used alone in practical applications; the frame 11 is an integrated frame. The lamp body 10 also includes a chassis and a light source assembly, the chassis has a receiving space, the light source assembly is arranged in the receiving space of the chassis, the frame 11 is located on the light emitting side of the chassis and connected to the chassis, and the chassis and the transition connecting plate 20 are arranged at intervals or in close contact.

[0063] like Figures 1 to 8As shown, there are one or more transition connecting plates 20. When there are multiple transition connecting plates 20, the multiple transition connecting plates 20 include a first connecting plate 201 and a second connecting plate 202. The first connecting plate 201 is connected to the base 30 to be installed, and the second connecting plate 202 is connected to the lamp body 10. The adjustment structure is located between the first connecting plate 201 and the second connecting plate 202 and is connected to the first connecting plate 201 and the second connecting plate 202. In a specific embodiment of the present application, the first connecting plate 201 is detachably connected to the base 30 to be installed, and the second connecting plate 202 is detachably connected to the lamp body 10. By setting the adjustment structure between the first connecting plate 201 and the second connecting plate 202, the distance between the first connecting plate 201 and the second connecting plate 202 can be adjusted by the adjustment structure, and then the distance between the lamp body 10 and the base 30 to be installed can be adjusted, so as to achieve the adjustment of the height of the lamp body 10, and the height of the lamp body 10 relative to the ground can be adjusted as needed; in addition, during the adjustment process and the use process, the second connecting plate 202 always remains parallel to the lamp body 10, and the first connecting plate 201 always remains parallel to the base 30 to be installed. Therefore, the angle between the first connecting plate 201 and the second connecting plate 202 can be adjusted by adjusting the adjustment structure, that is, the inclination angle of the second connecting plate 202 relative to the first connecting plate 201 can be adjusted, thereby achieving the adjustment of the light-emitting direction of the lamp body 10, and the emission direction of the main light of the lamp body 10 can be adjusted as needed.

[0064] like Figure 1 As shown, Figure 1 It is shown that when there is only one transition connecting plate 20, the transition connecting plate 20 is magnetically connected to the side of the chassis of the lamp body 10 away from the frame 11 through a magnet 44, so that the transition connecting plate 20 and the chassis can be detachably connected. Specifically, the magnet 44 is in a strip shape, and two strip-shaped magnets 44 can be provided. The transition connecting plate 20 is rectangular, and the two magnets 44 are provided on one side surface of the rectangular transition connecting plate 20 and are located at the edge position. The extension direction of the two magnets 44 is parallel to the short side of the rectangular transition connecting plate 20. In an embodiment not shown in the figure, when there are multiple transition connecting plates 20, the second connecting plate 202 is detachably connected to the chassis through the magnet 44.

[0065] This application provides a variety of adjustment structures, such as Figures 2 to 8As shown, in different embodiments of the present application, the specific structure and adjustment method of the adjustment structure are different. Specifically, the adjustment structure includes one of a threaded component, a pivot component, a telescopic component and a bendable shaping hose 61, and the adjustment structure is one or more. When the adjustment structure is multiple, at least one group of opposite sides of the first connecting plate 201 is connected with an adjustment structure, and the number of the adjustment structures on the same side of the first connecting plate 201 is one or more. Similarly, at least one group of opposite sides of the second connecting plate 202 is connected with an adjustment structure, and the number of the adjustment structures on the same side of the second connecting plate 202 is one or more.

[0066] The adjustment structures in different implementations are described below with reference to the accompanying drawings.

[0067] like Figure 2 and Figure 3 As shown, in an optional embodiment, the adjustment structure is a threaded assembly, and the threaded assembly is a plurality of groups, preferably four groups. The first connecting plate 201 is composed of a rectangular plate and two connecting plates 203, and a group of opposite sides of the rectangular plate has a connecting plate 203 extending toward the second connecting plate 202, and the two sides are the two short sides of the rectangular plate, and the ends of the two connecting plates 203 facing the second connecting plate 202 both have a plate section bent outward, and outward here refers to the side away from the two connecting plates 203, and one or more threaded assemblies are arranged between each plate segment and the second connecting plate 202. Preferably, two groups of threaded assemblies are arranged between each plate segment and the second connecting plate 202, and the two groups of threaded assemblies on the same plate segment are arranged at intervals.

[0068] like Figure 3 As shown, the thread assembly includes an adjusting screw 71 and a threaded member 72, the plate section has a through hole, one end of the adjusting screw 71 is rotatably arranged at the through hole, the threaded member 72 is arranged on the second connecting plate 202, the threaded member 72 is arranged corresponding to the through hole, and the other end of the adjusting screw 71 is threadedly connected with the second connecting plate 202 through the threaded member 72. The adjusting screw 71 has two limiting flanges. When the adjusting screw 71 is arranged in the through hole, the two limiting flanges are respectively located at the upper and lower sides of the through hole, thereby limiting the upward or downward movement of the adjusting screw 71, so that the adjusting screw 71 can rotate at the through hole but will not move up and down. The threaded member 72 is actually a nut, and the adjusting screw 71 and the threaded member 72 have mutually matched threaded sections. In this arrangement, the adjusting screw 71 is rotated to make the threaded member 72 move in its height direction, thereby driving the second connecting plate 202 to move up and down, adjusting the distance between the second connecting plate 202 and the first connecting plate 201, and thereby realizing the adjustment of the height of the lamp body 10.

[0069] Specifically, since two sets of threaded components are provided on both plate segments, when only the threaded components on one plate segment are adjusted, the angle between the second connecting plate 202 and the first connecting plate 201 can be changed, thereby making the second connecting plate 202 tilted, and realizing the independent adjustment of the light-emitting direction of the lamp body 10. When the threaded components on the two plate segments are adjusted at the same time, so that the second connecting plate 202 and the two plate segments keep moving parallel, the independent adjustment of the height of the lamp body 10 can be realized. Of course, in actual applications, the height and light-emitting direction of the lamp body 10 can be adjusted at the same time.

[0070] In addition, in this embodiment, the first connecting plate 201 can be detachably connected to the base 30 to be installed by screws 46, and the second connecting plate 202 can be detachably connected to the frame 11 by clamping keels 211, but it is not limited thereto.

[0071] like Figure 4 and Figure 5 As shown, in another optional embodiment, the adjustment structure is a pivot assembly, and the pivot assembly is provided in multiple groups, preferably four groups. The first connecting plate 201 and the second connecting plate 202 are both rectangular plates, and the short sides of the two connecting plates are parallel to each other. One side of the four pivot assemblies is pivotally connected to the four corners of the first connecting plate 201, and the other side of the four pivot assemblies is pivotally connected to the four corners of the second connecting plate 202.

[0072] Specifically, a set of pivoting assemblies includes at least two pivoting plates 81 that are pivotally connected, and the sides of the two pivoting plates 81 that are away from each other are pivotally connected to the edges of the first connecting plate 201 and the second connecting plate 202, respectively. Specifically, the pivoting assembly also includes a plurality of rotating shafts 82, and both ends of each pivoting plate 81 have rotating shaft holes for the rotating shafts 82 to pass through, and the four corners of the first connecting plate 201 and the four corners of the second connecting plate 202 are provided with rotating shaft holes. Taking a set of pivoting assemblies as an example, the rotating shaft hole at one end of a pivoting plate 81 corresponds to a rotating shaft hole of the first connecting plate 201, and a rotating shaft 82 passes through the two rotating shaft holes to realize the pivotal connection between the pivoting plate 81 and the first connecting plate 201. The rotation axis hole at the other end of the pivot plate 81 corresponds to the rotation axis hole at one end of another pivot plate 81, and another rotation axis 82 passes through the two rotation axis holes to realize the pivot connection of the two pivot plates 81. The rotation axis hole at the other end of the pivot plate 81 corresponds to a rotation axis hole of the second connecting plate 202, and another rotation axis 82 passes through the two rotation axis holes to realize the pivot connection of the pivot plate 81 and the second connecting plate 202. By simultaneously adjusting the included angles of the two pivot plates 81 of the four sets of pivot assemblies to be the same or different, the inclination angle of the second connecting plate 202 relative to the first connecting plate 201 and the distance between the two can be adjusted, thereby realizing the adjustment of the height of the lamp body 10 and the light emitting direction.

[0073] In addition, in this embodiment, the first connecting plate 201 can be detachably connected to the base 30 to be installed by screws 46, and the second connecting plate 202 can be detachably connected to the frame 11 by clamping keels 211, but it is not limited thereto.

[0074] like Figure 6 and Figure 7 As shown, in another optional embodiment, the adjustment structure is a telescopic assembly, which is a group. The telescopic assembly includes a telescopic tube 91, a telescopic rod 92 and a locking piece 93. One end of the telescopic tube 91 is connected to the center position of the first connecting plate 201, and the telescopic rod 92 is telescopically arranged in the telescopic tube 91 by the other end of the telescopic tube 91. The locking piece 93 is arranged between the telescopic tube 91 and the telescopic rod 92, specifically at one side end of the telescopic tube 91 facing the second connecting plate 202, and the locking piece 93 is specifically a connecting rod nut.

[0075] like Figure 6 and Figure 7 As shown, the telescopic rod 92 has a universal ball 921 at one end away from the first connecting plate 201, and the second connecting plate 202 has a universal seat 94 that cooperates with the universal ball 921. The universal seat 94 is located at the center of the second connecting plate 202. The adjustment structure also includes a universal cover 95, which is used to limit the universal ball 921 in the universal seat 94, so that the universal ball 921 can rotate in the universal seat 94 but will not separate from the universal seat 94. When the connecting rod nut is loosened, the telescopic rod 92 can move, and the height of the lamp body 10 can be adjusted at this time; when the connecting rod nut is tightened, the relative position of the telescopic rod 92 and the telescopic tube 91 is fixed, and the height of the lamp body 10 can be locked; the universal cover 95 and the universal seat 94 can rotate around the universal ball 921 in space, and the universal cover 95 is connected to the universal seat 94. The tightness of the two can adjust the tightness of the connection between the universal ball 921 and the universal seat 94, so that the universal seat 94 can rotate relative to the universal ball 921, thereby adjusting the light-emitting direction and angle of the lamp body 10.

[0076] In addition, in this embodiment, the first connecting plate 201 can be detachably connected to the base 30 to be installed by screws 46, and the second connecting plate 202 can be detachably connected to the frame 11 by clamping keels 211, but it is not limited thereto.

[0077] like Figure 8 As shown, in another optional embodiment, the adjustment structure is a bendable shaping hose 61, and in this case, the bendable shaping hose 61 is one. The two ends of the bendable shaping hose 61 are respectively connected to the center position of the first connecting plate 201 and the center position of the second connecting plate 202. The bendable shaping hose 61 has a certain structural strength, and the shape of the bendable shaping hose 61 can be adjusted by external force. It is flexible and can be bent. Therefore, when the bendable shaping hose 61 is bent and twisted, the height and light-emitting direction of the lamp body 10 can be adjusted at the same time.

[0078] In addition, in this embodiment, the first connecting plate 201 can be detachably connected to the base 30 to be installed by screws 46, and the second connecting plate 202 can be detachably connected to the frame 11 by clamping keels 211, but it is not limited thereto.

[0079] The present application also provides a variety of detachable connection methods between the transition connecting plate 20 and the lamp body 10. Figures 9 to 17 As shown, the transition connecting plate 20 is detachably connected to the lamp body 10, and the transition connecting plate 20 has an arm structure 21 extending toward the frame 11, and the end of the arm structure 21 has a second connecting piece. After the lamp body 10 and the transition connecting plate 20 are installed in place, the first connecting piece and the second connecting piece stop and cooperate in the disassembly direction of the lamp body 10. This arrangement enables the lamp body 10 of the present application to be detachably connected to the second connecting piece of the transition connecting plate 20 through the first connecting piece on the frame 11, thereby realizing the detachable connection between the lamp body 10 and the transition connecting plate 20, and then the transition connecting plate 20 can be installed to the desired position according to actual needs, thereby expanding the application range of the flat lamp device. At the same time, it also reduces the difficulty of disassembly and assembly, improves the convenience of disassembly and assembly, and improves the efficiency of disassembly and assembly.

[0080] refer to Fig. 9 As shown in , the frame 11 includes a frame body and a connecting section 112, at least one set of opposite sides of the frame body is provided with a connecting section 112, the connecting section 112 is perpendicular to the frame body, and the side of the connecting section 112 close to the transition connecting plate 20 has a first connecting member, the first connecting member is located on the inner side of the connecting section 112, the inner side here refers to the side surface of the connecting section 112 facing the chassis, and the first connecting member is a convex structure 12 or a groove structure; the transition connecting plate 20 has at least two arm structures 21 arranged at intervals, and each arm structure 21 has a second connecting member. The frame body is in the shape of a hollow quadrilateral flat plate. In the specific embodiment of the present application, there are two connecting sections 112 and arm structures 21, and the two second connecting members of the two arm structures 21 correspond to the two first connecting members on the two connecting sections 112 in a one-to-one manner. Of course, more than two arm structures 21 and more than two connecting sections 112 can be set according to actual needs, but it is necessary to ensure that the number of arm structures 21 is equal to the number of connecting sections 112.

[0081] Specifically, the outer shape of the frame body is rectangular, and a group of short sides of the rectangular frame body are provided with a connecting section 112, the connecting section 112 is plate-shaped, the width of the connecting section 112 is equal to the short side of the frame body, and the height of the connecting section 112 can be set according to actual conditions. The arm structure 21 is plate-shaped, and the width of the arm structure 21 is equal to the width of the body of the transition connecting plate 20, and the height of the arm structure 21 can be set according to actual conditions, and it is sufficient to ensure that the transition connecting plate 20 and the lamp body 10 are spaced apart.

[0082] Specifically, the first connecting member is a protruding structure 12, which has a guide surface 121 and a stop surface 122 connected in sequence at an angle. The stop surface 122 is arranged away from the transition connecting plate 20 relative to the guide surface 121, and the second connecting member contacts the stop surface 122 in the disassembly direction of the lamp body 10 to stop.

[0083] The following describes various detachable connection methods between the frame 11 of the lamp body 10 and the transition connecting plate 20 of the present application in conjunction with specific embodiments. In the following three embodiments, the structure of the lamp body 10 is the same, and the arm structure 21 and / or the second connecting member of the transition connecting plate 20 are different.

[0084] In an alternative embodiment, if Figures 9 to 11 As shown, a pair of opposite sides of the frame body are provided with connecting sections 112, and the opposite sides are a pair of short sides of the frame body. The two connecting sections 112 have a first connecting member at one end close to the transition connecting plate 20, and the two first connecting members are located on the outer side of the connecting section 112 where they are located. Specifically, there are two arm structures 21 on the transition connecting plate 20, and the two arm structures 21 are parallel to the disassembly direction of the lamp body 10. The lower ends of the two arm structures 21 have a second connecting member, and the second connecting member is a clamping protrusion 22, which is located on the outer side of the arm structure 21, and the clamping protrusion 22 contacts the stop surface 122 for stopping.

[0085] In the process of installing the lamp body 10 on the transition connecting plate 20, the clamping protrusion 22 is initially on the outside of the connecting section 112, that is, on the side of the connecting section 112 where the protruding structure 12 is not provided. When the frame 11 is pressed and installed in the vertical direction, a force in the vertical direction inward is generated at the guide surface 121 of the protruding structure 12 of the frame 11 to squeeze the clamping protrusion 22, and at the same time, the arm structure 21 is deformed and tilted inward, so that the clamping protrusion 22 and the protruding structure 12 are smoothly matched. At this time, the clamping protrusion 22 and the protruding structure 12 are stopped and matched in the disassembly direction of the lamp body 10, so that the lamp body 10 and the transition connecting plate 20 are installed. When the lamp body 10 needs to be disassembled, the clamping protrusion 22 can be separated from the protruding structure 12 by pressing the arm structure 21, so that the installation and disassembly operations of the lamp body 10 are convenient and quick, and the disassembly efficiency is improved.

[0086] In this embodiment, when there are multiple transition connecting plates 20, the transition connecting plate 20 mentioned above is the second connecting plate 202. The first connecting plate 201 is detachably connected to the base 30 to be installed by screws 46, but is not limited thereto.

[0087] In another alternative embodiment, Figure 12 to Figure 14 As shown, the difference between this embodiment and the above embodiment lies in that the second connecting member is different.

[0088] Specifically, the second connecting member includes a pin structure 23, an elastic member 24 and a U-shaped structure 25 located at the end of the arm structure 21. The U-shaped structure 25 has two plate structures arranged opposite to each other. One of the two plate structures is formed by extending from the arm structure 21. The other plate structure of the two plate structures is located on the inner side of the arm structure 21. Both plate structures are parallel to the disassembly direction of the lamp body 10. The disassembly direction of the lamp body 10 is Fig.13 Middle vertical direction.

[0089] like Fig.13 and Fig.14 As shown, the U-shaped structure 25 is integrally formed with the arm structure 21. The U-shaped structure 25 is equivalent to a structure formed by bending the bottom of the arm structure 21 twice inward. One end of the ejector structure 23 is elastically connected to one of the two plate structures through the elastic member 24, and the other end of the ejector structure 23 passes through the other of the two plate structures and contacts the stop surface 122 for stopping. The ejector structure 23 has a circumferential flange 231. When the ejector structure 23 contacts the stop surface 122 for stopping, the circumferential flange 231 is located between the two plate structures. Specifically, the circumferential flange 231 is located between the two ends of the ejector structure 23 to divide the ejector structure 23 into two sections. The elastic member 24 is a spring. The spring is sleeved on the ejector structure 23 by the right side of the ejector structure 23 and the left side of the spring abuts against the circumferential flange 231. The right side of the spring abuts against the plate structure located on the inner side of the two plate structures, and the right end of the spring is spaced from the right end of the ejector structure 23. A section of the ejector pin structure 23 located on the left side of the circumferential flange 231 passes through the outer plate structure of the two plate structures and contacts the stop surface 122 for stopping.

[0090] During the process of installing the lamp body 10 on the transition connecting plate 20, the ejector structure 23 is initially in the outermost position due to the compression of the spring, that is, outside the connecting section 112. When the frame 11 is installed vertically upward, the protruding end of the ejector structure 23 is compressed by the guide surface 121, thereby compressing the spring to shrink it, and the ejector structure 23 moves inward, and then as the frame 11 moves upward, the end of the ejector structure 23 contacts the stop surface 122 after passing through the guide surface 121, thereby achieving the installation of the lamp body 10 and the transition connecting plate 20. When the lamp body 10 needs to be disassembled, the ejector structure 23 is squeezed to separate the ejector from the stop surface 122.

[0091] In this embodiment, when there are multiple transition connecting plates 20, the transition connecting plate 20 mentioned above is the second connecting plate 202. The first connecting plate 201 is detachably connected to the base 30 to be installed by screws 46, but is not limited thereto.

[0092] In another alternative embodiment, Figures 15 to 17As shown, the difference between this embodiment and the above embodiment lies in that the second connecting member and the arm structure 21 are different.

[0093] like Figures 15 to 17 As shown, an arm structure 21 includes two clamping keels 211, and the clamping keel 211 is composed of a plurality of plate segments connected in sequence at an angle. The plate segment closest to the frame 11 among the plurality of plate segments is an arc plate 212. A space for clamping the connecting segment 112 is formed between the arc plates 212 of the two clamping keels 211. The connecting segment 112 extends into the space and enables the first connecting member to stop and cooperate with the two arc plates 212, specifically, enables the protruding structure 12 to stop and cooperate with the two arc plates 212 in the disassembly direction of the lamp body 10.

[0094] Specifically, a clamping keel 211 is composed of at least three plate segments, and the lowest plate segment among the three plate segments is an arc plate 212. The raised segments of the arc plates 212 of the two clamping keels 211 are close to each other. This arrangement makes the clamping space for clamping the connecting segment 112 formed between the two arc plates 212 smaller, which is conducive to ensuring the clamping strength and clamping stability. The side of the arc plate 212 away from the transition connecting plate 20 has an outer flange 2121, and the end of the outer flange 2121 away from the transition connecting plate 20 is bent toward the direction of the transition connecting plate 20. The outer flanges 2121 of the two arc plates 212 are located on the side away from each other. This arrangement is conducive to pressing the connecting segment 112 between the two arc plates 212 later.

[0095] like Fig.17 As shown, the ratio between the extension length L1 of the outer flange 2121 and the extension length L2 of the raised section of the arc plate 212 for clamping the connecting section 112 is greater than or equal to 0.2 and less than or equal to 10. Such a configuration is conducive to ensuring the structural strength of the arc plate 212, thereby avoiding the risk of deformation of the arc plate 212 during the installation and disassembly process of the lamp body 10, and ensuring the stability of the arc plate 212 clamping the connecting section 112. At least part of the raised section of the arc plate 212 has a plane structure for contacting the connecting section 112, and such a configuration is conducive to increasing the contact area between the arc plate 212 and the connecting section 112, thereby facilitating increasing the stability of the two arc plates 212 clamping the connecting section 112. Specifically, the surfaces of the two arc plates 212 facing each other have a plane structure, and the two plane structures are arranged opposite to each other. Preferably, L1 is greater than or equal to 2 mm and less than or equal to 20 mm, and L2 is greater than or equal to 2 mm and less than or equal to 10 mm.

[0096] In this embodiment, the two clamping keels 211 are composed of three plate segments, and the distance between the two plate segments of the two clamping keels 211 farthest from the frame 11 gradually decreases from top to bottom, and the distance between the two plate segments of the two clamping keels 211 located in the middle is always equal from top to bottom. The arm structure 21 and the main body of the transition connecting plate 20 can be detachably connected or integrally formed. In the process of installing the lamp body 10 to the transition connecting plate 20, the two clamping keels 211 are initially in a clamping state. In the process of installing the frame 11 upward, one end of the connecting section 112 having the protruding structure 12 is inserted into the two arc plates 212 from between the two arc plates 212, so that the connecting section 112 extends into the space between the two arc plates 212 and the two arc plates 212 clamp the connecting section 112, and at the same time, the protruding structure 12 and the two arc plates 212 are stopped and matched in the disassembly direction of the lamp body 10. When the lamp body 10 needs to be disassembled, the clamping space between the two arc plates 212 is enlarged to break away from the clamping state, and at the same time, the protruding structure 12 is separated from the stopping state with the two arc plates 212 .

[0097] In this embodiment, when there are multiple transition connecting plates 20, the transition connecting plate 20 mentioned above is the second connecting plate 202. The first connecting plate 201 is detachably connected to the base 30 to be installed by screws 46, but is not limited thereto.

[0098] The present application also provides a variety of detachable connection methods between the transition connecting plate 20 and the base body 30 to be installed. Figures 18 to 28 As shown, the transition connecting plate 20 is detachably connected to the base 30 to be installed through the connecting structure. This is conducive to ensuring the detachability of the transition connecting plate 20 and the base 30 to be installed. The transition connecting plate 20 can be installed on the base 30 to be installed, or the transition connecting plate 20 can be removed from the base 30 to be installed as needed, thereby realizing flexible installation and removal of the lamp body 10, so that the lamp body 10 can be installed at any position as required, expanding the application range, and at the same time reducing the difficulty of installation and removal, and improving the removal efficiency.

[0099] The following describes various detachable connection methods between the transition connecting plate 20 and the base body 30 to be installed in the present application in combination with specific embodiments.

[0100] In an alternative embodiment, if Fig.18 and Fig.19As shown, the transition connecting plate 20 has a protruding portion 51, the base 30 to be installed has a mounting hole 31, and the connection structure includes a stopper 41, the end of the protruding portion 51 passes through the mounting hole 31, the stopper 41 is connected to the end of the protruding portion 51, and at least a part of the stopper 41 abuts against the surface of the side of the base 30 to be installed away from the lamp body 10, so that the stopper 41 and the base 30 to be installed are stopped and matched in the disassembly direction of the transition connecting plate 20. In this arrangement, the side of the transition connecting plate 20 having the protruding portion 51 is aligned with the mounting hole 31, so that the end of the protruding portion 51 protrudes from the mounting hole 31, and then the stopper 41 is connected to the end of the protruding portion 51 and the stopper 41 is matched with the back side of the base 30 to be installed, so as to limit the movement of the transition connecting plate 20 in the disassembly direction, thereby realizing the installation of the transition connecting plate 20 and the base 30 to be installed, and then realizing the installation of the lamp body 10.

[0101] Specifically, the transition connecting plate 20 is spaced apart or fitted to the base 30 to be installed. Optionally, there are one or more extensions 51 and one or more stoppers 41.

[0102] In this embodiment, there is only one protruding portion 51 and the end of the protruding portion 51 has a clamping head 511, and the stopper 41 has a clamping notch. The clamping notch is clamped with the protruding portion 51 and cooperates with the clamping head 511 in the disassembly direction of the transition connecting plate 20. At least one side end of the stopper 41 cooperates with the side surface of the base 30 to be installed that is away from the lamp body 10 in the disassembly direction of the transition connecting plate 20, that is, fits. It should be noted that the clamping head 511 of the protruding portion 51 is in the shape of a circular sheet, and the protruding portion 51 is columnar as a whole except for the clamping head 511, and the stopper 41 is in the shape of a strip plate. There are one or more stoppers 41 in the shape of a strip plate. When there is only one stopper 41, the clamping notch is located between the two ends of the stopper 41. After the clamping notch and the protruding portion 51 are clamped into place, the two ends of the stopper 41 are respectively fitted with two positions of the base 30 to be installed on the side of the mounting hole 31 to achieve a stop fit; when there are multiple stoppers 41, one end of each stopper 41 has a clamping notch, and the other end of each stopper 41 is a stop end. The clamping notch of each stopper 41 is clamped with the protruding portion 51 and stops with the clamping head 511, and the stop end of each stopper 41 abuts against different positions of the base 30 to be installed on the side of the mounting hole 31, that is, a stop fit. The plurality of stoppers 41 may be arranged in a divergent shape with the extension portion 51 as the center.

[0103] exist Fig.18 and Fig.19 In the figure, there are two stoppers 41, and the angle between the two strip-shaped stoppers 41 is 180°. This arrangement is conducive to ensuring the uniformity of the stopping force of the two stoppers 41 on the back side of the installation base 30, and ensuring the connection stability between the transition connecting plate 20 and the installation base 30.

[0104] In addition, the two stoppers 41 in this embodiment are both rotatable around the extension 51, and the two stoppers 41 can be rotated independently to adjust their positions and angles. During installation, the two stoppers 41 can be firstly clamped on the extension 51, and the two stoppers 41 can be rotated until the two overlap. Since the length of one stopper 41 is less than the diameter of the mounting hole 31, the stopper 41 can easily pass through the mounting hole 31. After the transition connecting plate 20 and the base 30 to be installed are installed in place, and the two stoppers 41 are located on the back side of the base 30 to be installed, the two stoppers 41 are rotated to an angle of 180°. At this time, the two stoppers 41 are in the radial direction of the mounting hole 31, and the total length of the two stoppers 41 is greater than the diameter of the mounting hole 31. At this time, the stop ends of the two stoppers 41 can abut against the back of the base 30 to be installed, thereby achieving the stop, realizing the installation of the transition connecting plate 20 and the base 30 to be installed, and then realizing the installation of the lamp body 10. When disassembly is required, it is only necessary to rotate one of the two stoppers 41 and adjust the included angle of the two stoppers 41 to reduce it or make the two stoppers 41 overlap. The stoppers 41 can be easily adjusted out of the stop position, and the transition connecting plate 20 can be disengaged from the base 30 to be installed, thereby realizing the disassembly of the lamp body 10.

[0105] In another alternative embodiment, Fig. 20 and Fig.21 As shown, the difference between this embodiment and the above-mentioned embodiment lies in that the shape and number of the protruding parts 51 are different, and the structure of the stopper is different.

[0106] like Fig. 20 and Fig.21 As shown, there are multiple protruding parts 51 and multiple stoppers, and the multiple stoppers are arranged in a one-to-one correspondence with the multiple protruding parts 51. The stoppers include a spring clip 42 and a stop plate 43. The spring clip 42 includes two pivotally connected clamps, and the two clamps are pivotally connected through a rotating shaft 82 with a spring; one of the two clamps is connected to the protruding part 51 at a side away from the pivot end, and the other of the two clamps is connected to the stop plate 43. The stop plate 43 is strip-shaped, and one end of the strip-shaped stop plate 43 away from the clamp is matched with a stopper on the surface of the side of the base 30 to be installed that is away from the lamp body 10.

[0107] In this embodiment, there are two protruding parts 51, the two protruding parts 51 are arranged at intervals and the distance between the two protruding parts 51 is smaller than the diameter of the mounting hole 31, and there are two stoppers 41, and the stop plates 43 of the two stoppers 41 are arranged to be tilted outward. The pivot end of the spring clip 42 is located on the side away from the base 30 to be installed. One clamping plate of the spring clip 42 is fixedly connected to the end of the protruding part 51 through a fixing member 49, and the other clamping plate of the spring clip 42 is connected to one end of the stop plate 43, and the other end of the stop plate 43 abuts against the back of the base 30 to be installed on the side of the mounting hole 31, thereby achieving stop limit. The two protruding parts 51 are both in the shape of long strips, and the two spring clips 42 are located on the side where the two protruding parts 51 are away from each other.

[0108] During installation, first install the spring clip 42 and the stop plate 43 on the extension 51. The initial state of the spring clip 42 is that the two clamps are open. At this time, the stop plate 43 and the extension 51 are set at an acute angle. Then press the stop plate 43 in the direction close to the extension 51 to reduce the angle between the stop plate 43 and the extension 51, and then insert the extension 51 and the components thereon into the mounting hole 31. When the stop plate 43 and the spring clip 42 are at the back side of the base 30 to be installed, release the stop plate 43, the stop plate 43 automatically opens and is stuck on the back side of the base 30 to be installed, thereby achieving the installation of the lamp body 10. When the lamp body 10 needs to be removed, it is only necessary to press the stop plate 43 in the direction close to the extension 51 so that the stop plate 43 is out of the stop position, so that the extension 51 and the components thereon can be removed from the mounting hole 31, thereby achieving the disassembly work.

[0109] In another alternative embodiment, Fig. 22 As shown, the difference between this embodiment and the above embodiment is that the connection structure is different. Specifically, the connection structure is a magnet 44, and the transition connecting plate 20 and the base 30 to be installed are both magnetic structures. The transition connecting plate 20 is magnetically connected to the base 30 to be installed through the magnet 44, and the two side surfaces of the magnet 44 and the transition connecting plate 20 and the base 30 to be installed are both flat, which is conducive to ensuring the stability of the magnetic connection.

[0110] Specifically, the number of the magnet 44 can be one or more. When there are multiple magnets 44, the multiple magnets 44 are arranged at intervals.

[0111] In another alternative embodiment, Fig.23As shown, the difference between this embodiment and the above embodiment is that the connection structure is different. Specifically, the connection structure is integrally formed with the transition connecting plate 20, and the connection structure is a nail 45, and the nail 45 has a pointed end. In this way, during installation, the nail 45 can be hammered into the base 30 to be installed by a hammer, so that the nail 45 can be firmly connected to the base 30 to be installed, so that the strength and tightness of the installation can be ensured. Specifically, one or more nails 45 on the connection structure can be provided, and when there are multiple nails 45, the multiple nails 45 are arranged in an array.

[0112] In another alternative embodiment, Fig.24 As shown, the difference between this embodiment and the above embodiment is that the connection structure is different. Specifically, the connection structure is a screw 46, and the transition connecting plate 20 is connected to the base 30 to be installed by the screw 46. Specifically, the surface of the lamp body 10 facing the transition connecting plate 20 has a recessed groove, the bottom of the recessed groove has a through hole, and the base 30 to be installed has a locking hole corresponding to the through hole. The screw 46 passes through the through hole from the side of the lamp body 10 facing the transition connecting plate 20 and is locked in the locking hole, thereby realizing the installation of the lamp body 10 and the base 30 to be installed. There are one or more screws 46. When there are multiple screws 46, the multiple screws 46 are arranged at intervals.

[0113] In another alternative embodiment, Fig.25 As shown, the connection structure is a hanging hole provided on the transition connecting plate 20, and the hanging hole is composed of an elliptical hole and an elongated hole connected to each other. The base 30 to be installed has a nail hook 32 that cooperates with the hanging hole. During installation, the hanging hole is hung into the nail hook 32, so that the nail hook 32 slides from the elliptical hole to the elongated hole and is at the end of the elongated hole, so that the transition connecting plate 20 fits the surface of the base 30 to be installed, and at the same time ensures the stable assembly of the transition connecting plate 20 and the base 30 to be installed. In order to distinguish the hanging hole of this embodiment from the hanging hole of the following embodiments, the hanging hole on the transition connecting plate 20 of this embodiment is defined as a first hanging hole. Specifically, the first hanging hole and the nail hook 32 that cooperate with each other are a group, and specifically multiple groups of first hanging holes and nail hooks 32 can be provided to ensure assembly stability.

[0114] In another alternative embodiment, Fig.26 and Fig. 27As shown, the connection structure and the transition connection plate 20 are integrally formed, and the connection structure is a hook 47, which is composed of two plate sections connected at right angles, and the base 30 to be installed has a hanging hole that cooperates with the hook 47, and the hanging hole is a long hole. In order to distinguish the hanging hole on the base 30 to be installed in this embodiment from the hanging hole in the above embodiment, the hanging hole on the base 30 to be installed in this embodiment is defined as a second hanging hole 33. By matching the hook 47 with the second hanging hole 33, the transition connection plate 20 is made to fit the surface of the base 30 to be installed, and at the same time, the stable assembly of the transition connection plate 20 and the base 30 to be installed is ensured. Four second hanging holes 33 of the base 30 to be installed can be set, and four hooks 47 on the connection structure can be set, and the four hooks 47 are set one-to-one with the four second hanging holes 33. In practical applications, it is not limited to four.

[0115] In another alternative embodiment, Fig.28 As shown, the transition connecting plate 20 has a connecting arm 26, which is located on the side of the transition connecting plate 20 away from the lamp body 10 and extends along the side away from the lamp body 10. The connecting arm 26 is a hollow structure, and the connecting structure includes a rope structure 48 and a fixing member 49. One end of the rope structure 48 is fixedly connected to the base 30 to be installed, and the other end of the rope structure 48 extends into the hollow connecting arm 26 and is detachably connected to the connecting arm 26 through the fixing member 49. The fixing member 49 is actually a screw. In this way, during installation, the transition connecting plate 20 can be installed with the base 30 to be installed by only extending the rope structure 48 into the connecting arm 26, and then using a screw to pass through the wall of the connecting arm 26 to lock the rope structure 48 in the connecting arm 26, thereby realizing the installation of the transition connecting plate 20 and the base 30 to be installed, thereby realizing the installation of the lamp body 10.

[0116] In summary, in the present application, various adjustment structures, various detachable connection methods between the transition connecting plate 20 and the base 30 to be installed, and various detachable connection methods between the transition connecting plate 20 and the frame 11 can be arbitrarily combined, not limited to the above-mentioned combinations and the combinations shown in the figures.
