Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and particularly to a lighting fixture. Background Technology

[0002] Over the years, lighting fixtures have evolved into many different types depending on their specific uses, such as floor lamps, table lamps, downlights, and spotlights. Among them, downlights are generally installed in the perimeter ceiling of bedrooms, living rooms, and bathrooms, and are a type of concealed lighting fixture embedded inside the ceiling.

[0003] Downlights consist of a housing and a lamp body. During installation, the housing is fixed to the ceiling, and the lamp body is secured inside the housing with screws and other fasteners. Then, plaster is used to fix the frame of the housing to the ceiling. However, this method of installing downlights has at least the following drawbacks: 1. The installation process is cumbersome; 2. When the downlight needs to be disassembled for maintenance, the lamp body and housing must be removed together, which requires damaging the plaster structure and may also damage the ceiling.

[0004] Besides downlights, some other lighting fixtures also have similar shapes and designs to downlights. For example, some spotlights have similar shapes and structures to downlights, and their installation and disassembly methods are similar to those of downlights. Therefore, they also have the aforementioned shortcomings. Summary of the Invention

[0005] The main objective of this invention is to provide a lighting fixture that addresses at least one deficiency in the prior art.

[0006] To achieve the above objectives, the present invention proposes a lamp fixture, comprising a housing and a lamp body disposed inside the housing. The housing has an illumination end and a mounting end. One end of the lamp body is provided with an illumination component, and the other end is provided with a mounting / removing seat. The illumination component is located near the illumination end, and the mounting / removing seat is located near the mounting end. A push rod is provided at the end of the lamp body near the mounting / removing seat. The mounting / removing seat has a push rod channel, and the push rod is axially movable within the push rod channel. A limiting structure channel connecting the push rod channel and the outer wall of the mounting / removing seat is provided within the limiting structure channel. An elastic limiting structure is provided within the limiting structure channel, and the elastic limiting structure can protrude from the outer wall of the mounting / removing seat or the inner wall of the push rod channel. The housing and the mounting / removing seat are provided with a mounting / removing seat limiting structure for restricting the movement of the mounting / removing seat towards the mounting end. The mounting / removing seat and the lamp body are provided with... A lamp body limiting structure is provided to restrict the lamp body from moving away from the mounting base; the inner wall of the outer shell is provided with a mounting groove, which extends circumferentially around the axis of the outer shell. When the mounting base is restricted from moving towards the mounting end, the limiting structure channel is directly opposite the mounting groove; the inner wall of the push rod and the push rod channel is provided with a push rod height switching structure, which is used to switch the push rod to a first height position or a second height position, such that: when the push rod is in the first height position, the limiting structure channel is directly opposite the mounting groove, the push rod presses against the elastic limiting structure, and the elastic limiting structure protrudes from the outer wall of the mounting base and is inserted into the mounting groove; when the push rod is in the second height position, the push rod disengages from the elastic limiting structure, the elastic limiting structure disengages from the mounting groove, and the elastic limiting structure protrudes from the inner wall of the push rod channel.

[0007] The beneficial effects of this invention are as follows: When installing the lamp body, push the lamp body into the inner side of the outer casing from the lighting end until the disassembly / assembly seat limiting structure restricts the movement of the disassembly / assembly seat towards the installation end. Continue pushing and / or rotating the lamp body, causing axial relative movement between the push rod and the disassembly / assembly seat. The push rod height switching structure holds the push rod in the first height position, allowing the push rod to maintain the state of pressing the elastic limiting structure, causing the elastic limiting structure to protrude from the outer wall of the disassembly / assembly seat and insert into the installation groove, thus completing the installation of the lamp body. When disassembling the lamp body, push and / or rotate the lamp body, and under the action of the push rod height switching structure, switch the lamp body to the second height position. The elastic limiting structure disengages from the installation groove, thus completing the disassembly of the lamp body. The lamp fixture of this invention can complete the separate installation and disassembly of the lamp body while the outer casing of the lamp fixture is fixedly installed on the ceiling. The lamp body installation is simple, and the ceiling will not be damaged during the lamp body disassembly process.

[0008] Preferably, the elastic limiting structure includes a limiting strip and a limiting strip elastic support structure. The limiting strip is axially movable within the limiting structure channel. A transmission part is provided at one end of the limiting strip near the top rod channel. The limiting strip elastic support structure is located within the limiting structure channel. The limiting strip elastic support structure can push the limiting strip towards the top rod channel and ensure that the transmission part is at least partially located within the top rod channel.

[0009] Preferably, the transmission part includes a transmission ramp, which is inclined towards the axis of the push rod channel in the direction from the lighting end to the mounting end. When the push rod moves from the side of the transmission part near the lighting end to the side of the transmission part near the mounting end, the push rod presses against the transmission ramp, causing the limiting strip to move toward the outer wall of the mounting base and protrude from the outer wall of the mounting base.

[0010] Preferably, the mounting base is provided with multiple limiting structure channels and multiple limiting strips. The multiple limiting strips are arranged circumferentially around the axis of the mounting base. The multiple limiting strips are correspondingly located in the multiple limiting structure channels, and the mounting groove is annular.

[0011] Preferably, the limiting strip is provided with a limiting strip limiting ring, which is used to restrict the movement of the limiting strip towards the top rod channel. The elastic support structure of the limiting strip is a limiting strip support spring, which is sleeved on the limiting strip.

[0012] Preferably, the top rod is rotatably connected to the lamp body. The top rod height switching structure includes a limiting block on the outer wall of the top rod, a limiting block clearance groove and multiple limiting grooves on the inner wall of the top rod channel. The multiple limiting grooves include multiple first limiting grooves and multiple second limiting grooves. The extension directions of the first and second limiting grooves are the same as the extension direction of the top rod channel. The multiple first limiting grooves and multiple second limiting grooves are circumferentially arranged on the inner wall of the top rod channel and are alternately arranged. The openings of the first and second limiting grooves are flush and both face the mounting end. The depth 'a' of the first limiting groove is... The depth b of the second limiting groove is less than the depth of the second limiting groove, so the limiting block can be placed in either the first or second limiting groove. The limiting block clearance groove is arranged around the axis of the push rod channel. The side of the limiting block clearance groove near the lighting end connects the first and second limiting grooves. The side of the limiting block clearance groove near the installation end is provided with multiple first push rod rotation guide ramps and multiple push rod rotation limiting surfaces. These multiple first push rod rotation guide ramps and multiple push rod rotation limiting surfaces are arranged circumferentially around the axis of the push rod channel and are alternately arranged. The end of the limiting block near the installation end is provided with a surface that matches the first push rod rotation guide ramp. A second push rod rotation guide slope is provided; a spacer is provided between adjacent first and second limiting grooves, and a third push rod rotation guide slope is provided at the end of the spacer near the limiting block clearance groove. A fourth push rod rotation guide slope, matching the third push rod rotation guide slope, is provided at the end of the limiting block near the lighting end. The rotational guidance of the first and second push rod rotation guide slopes on the push rod is the same as that of the third and fourth push rod rotation guide slopes on the push rod, so that when the limiting block moves from the limiting groove towards the installation end... The limiting block enters the limiting block clearance groove. The first and second push rods rotate the guide ramps to rotate the push rod until the limiting block abuts against the push rod rotation limiting surface, with the limiting block facing the spacer. When the limiting block moves from the limiting block clearance groove toward the lighting end, the third and fourth push rods rotate the guide ramps to rotate the push rod until the limiting block faces and falls to the bottom of the adjacent limiting groove. When the limiting block is at the bottom of the first limiting groove, the push rod is at the first height position. When the limiting block is at the bottom of the second limiting groove, the push rod is at the second height position.

[0013] Preferably, a top rod support spring is provided in the top rod channel. One end of the top rod support spring is connected to the top rod, and the other end is connected to the top of the top rod channel. The top rod support spring can push the top rod to move towards the lighting end.

[0014] Preferably, the lamp body has a push rod receiving groove at one end near the mounting base. The extension direction of the push rod receiving groove is the same as the extension direction of the outer shell. The push rod is located in the push rod receiving groove and can move axially and / or rotate circumferentially. A mounting base support spring is provided in the push rod receiving groove. The mounting base support spring is sleeved on the push rod. One end of the mounting base support spring is connected to the bottom of the push rod channel, and the other end is connected to the bottom of the push rod receiving groove. The mounting base support spring can push the lamp body away from the mounting base.

[0015] Preferably, the disassembly seat limiting structure includes a disassembly seat limiting ring disposed on the inner wall of the housing and an annular limiting step disposed on the outer wall of the disassembly seat.

[0024] like Figures 1 to 11 As shown, a lamp includes a housing 1 and a lamp body 2 disposed inside the housing 1. The housing 1 has an illumination end 11 and a mounting end 12. One end of the lamp body 2 is provided with an illumination component 21, and the other end is provided with a mounting base 22. The illumination component 21 is close to the illumination end 11, and the mounting base 22 is close to the mounting end 12. The end of the lamp body 2 near the mounting base 22 is provided with a push rod 23. The mounting base 22 is provided with a push rod channel 221, and the push rod 23 is axially movable within the push rod channel 221. The mounting base 22 is provided with a limiting structure channel 222 connecting the push rod channel 221 and the outer wall of the mounting base 22. The limiting structure channel 222 is provided with an elastic limiting structure, which can protrude from the outer wall of the mounting base 22 or the inner wall of the push rod channel 221. The housing 1 and the mounting base 22 are provided with a mounting base limiting structure 25 for limiting the movement of the mounting base 22 towards the mounting end 12. The mounting base 22 and the lamp body 2 are provided with a limiting structure 25 for limiting the movement of the mounting base 22 towards the mounting end 12. The lamp body 2 is positioned away from the mounting base 22 by a lamp body limiting structure 26; the inner wall of the outer shell 1 is provided with a mounting groove 13, which extends circumferentially around the axis of the outer shell 1. When the mounting base 22 is restricted from moving towards the mounting end 12, the limiting structure channel 222 is directly opposite the mounting groove 13; the inner wall of the push rod 23 and the push rod channel 221 is provided with a push rod height switching structure 224, which is used to switch the push rod 23 to a first height position 4 or a second height position 5, such that: when the push rod 23 is in the first height position 4, the limiting structure channel 222 is directly opposite the mounting groove 13, the push rod 23 presses against the elastic limiting structure, the elastic limiting structure protrudes from the outer wall of the mounting base 22 and is inserted into the mounting groove 13; when the push rod 23 is in the second height position 5, the push rod 23 disengages from the elastic limiting structure, the elastic limiting structure disengages from the mounting groove 13, and the elastic limiting structure protrudes from the inner wall of the push rod channel 221.

[0025] When installing the lamp body 2, push the lamp body 2 from the lighting end 11 into the inside of the outer casing 1 until the disassembly and assembly seat limiting structure 25 restricts the movement of the disassembly and assembly seat 22 towards the installation end 12. Continue to push and / or rotate the lamp body 2, so that the push rod 23 and the disassembly and assembly seat 22 generate axial relative movement. The push rod height switching structure 224 holds the push rod 23 at the first height position 4, so that the push rod 23 can maintain the state of pressing the elastic limiting structure, so that the elastic limiting structure protrudes from the outer wall of the disassembly and assembly seat 22 and is inserted into the installation groove 13, completing the installation of the lamp body 2. When disassembling the lamp body 2, push and / or rotate the lamp body 2. Under the action of the push rod height switching structure 224, the lamp body 2 is switched to the second height position 5, and the elastic limiting structure disengages from the installation groove 13, completing the disassembly of the lamp body 2. In this embodiment, the lamp can be installed and disassembled separately with the outer casing 1 of the lamp fixedly installed on the ceiling. The lamp body 2 is easy to install, and the ceiling will not be damaged during the disassembly of the lamp body 2.

[0026] In some specific embodiments, the elastic limiting structure includes a limiting strip 24 and a limiting strip elastic support structure 2221. The limiting strip 24 is axially movable within the limiting structure channel 222. A transmission part 241 is provided at one end of the limiting strip 24 near the top rod channel 221. The limiting strip elastic support structure 2221 is located within the limiting structure channel 222. The limiting strip elastic support structure 2221 can push the limiting strip 24 towards the top rod channel 221, and make the transmission part 241 at least partially located within the top rod channel 221.

[0027] When the push rod 23 is at the first height position 4, the push rod 23 presses the transmission part 241, causing the end of the limiting strip 24 away from the transmission part 241 to protrude from the outer wall of the disassembly and assembly seat 22 and be inserted into the mounting groove 13.

[0028] When the push rod 23 is at the second height position 5, the push rod 23 disengages from the transmission part 241, the end of the limiting strip 24 away from the transmission part 241 disengages from the mounting groove 13, the transmission part 241 protrudes from the inner wall of the push rod channel 221, and the transmission part 241 is at least partially located in the push rod channel 221.

[0029] In some specific embodiments, the transmission part 241 includes a transmission ramp that is inclined toward the axis of the push rod channel 221 in the direction from the lighting end 11 to the mounting end 12. When the push rod 23 moves from the side of the transmission part 241 near the lighting end 11 to the side of the transmission part 241 near the mounting end 12, the push rod 23 presses the transmission ramp, causing the limiting strip 24 to move toward the outer wall of the disassembly and assembly base 22 and protrude from the outer wall of the disassembly and assembly base 22.

[0030] During installation, the top rod 23 moves from the lighting end 11 to the mounting end 12, pressing the transmission inclined surface, causing the limiting strip 24 to gradually move towards the outer wall of the mounting base 22 until it protrudes from the outer wall of the mounting base 22 and is inserted into the mounting groove 13.

[0031] In some specific embodiments, the disassembly base 22 is provided with multiple limiting structure channels 222 and multiple limiting strips 24. The multiple limiting strips 24 are arranged circumferentially around the axis of the disassembly base 22, and the multiple limiting strips 24 are correspondingly provided in the multiple limiting structure channels 222. The mounting groove 13 is annular.

[0032] When the push rod 23 moves from the side of the transmission part 241 near the lighting end 11 to the side of the transmission part 241 near the mounting end 12, it can simultaneously squeeze the transmission slope of multiple limiting strips 24, and at the same time move multiple limiting strips 24 towards the outer wall of the mounting base 22, so that multiple limiting strips 24 are simultaneously inserted into the mounting groove 13, which helps to improve the installation stability of the lamp body 2.

[0033] In some specific embodiments, the limiting strip 24 is provided with a limiting strip limiting ring 242, which is used to restrict the movement of the limiting strip 24 toward the top rod channel 221. The limiting strip elastic support structure 2221 is a limiting strip support spring, which is sleeved on the limiting strip 24. One end of the limiting strip support spring is connected to the limiting strip limiting ring 242, and the other end is connected to the side wall of the disassembly and assembly base 22.

[0034] After the push rod 23 switches from the first height position 4 to the second height position 5, the push rod 23 no longer presses against the transmission part 241. At this time, the limit bar support spring applies a force to the limit bar 24, causing the limit bar 24 to move towards the push rod channel 221, and causing the limit bar 24 to disengage from the mounting groove 13 and the transmission part 241, at least partially located within the push rod channel 221, thus completing the reset of the limit bar 24.

[0035] In some specific embodiments, the top rod 23 is rotatably connected to the lamp body 2. The top rod height switching structure 224 includes a limiting block 3 disposed on the outer wall of the top rod 23, a limiting block clearance groove 229 disposed on the inner wall of the top rod channel 221, and a plurality of limiting grooves. The plurality of limiting grooves includes a plurality of first limiting grooves 225 and a plurality of second limiting grooves 226. The extending directions of the first limiting grooves 225 and the second limiting grooves 226 are the same as the extending direction of the top rod channel 221. The plurality of first limiting grooves 225 and the plurality of second limiting grooves 226 are arranged circumferentially on the inner wall of the top rod channel 221 and are alternately arranged. The openings of the first limiting grooves 225 and the second limiting grooves 226 are flush and both face the mounting end 12. The depth a of the first limiting groove 225 is... The depth b of the second limiting groove 226 is less than that of the limiting block 3, which can be placed in the first limiting groove 225 or the second limiting groove 226. The limiting block clearance groove 229 is arranged around the axis of the push rod channel 221. The side of the limiting block clearance groove 229 near the lighting end 11 is connected to the first limiting groove 225 and the second limiting groove 226. The side of the limiting block clearance groove 229 near the mounting end 12 is provided with multiple first push rod rotation guide inclined surfaces 2241 and multiple push rod rotation limiting surfaces 228. The multiple first push rod rotation guide inclined surfaces 2241 and multiple push rod rotation limiting surfaces 228 are arranged circumferentially around the axis of the push rod channel 221 and are alternately arranged. The end of the limiting block 3 near the mounting end 12 is provided with a surface that matches the first push rod rotation guide inclined surface 2241. A second push rod rotation guide slope 2242 is provided; a spacer 227 is provided between adjacent first limiting grooves 225 and second limiting grooves 226. A third push rod rotation guide slope 2243 is provided at the end of the spacer 227 near the limiting block clearance groove 229. A fourth push rod rotation guide slope 2244 is provided at the end of the limiting block 3 near the lighting end 11, which matches the third push rod rotation guide slope 2243. The rotational guidance of the first push rod rotation guide slope 2241 and the second push rod rotation guide slope 2242 on the push rod 23 is the same as the rotational guidance of the third push rod rotation guide slope 2243 and the fourth push rod rotation guide slope 2244 on the push rod 23, so that the limiting block 3 moves from the limiting groove to the mounting end 12. When the limiting block 3 enters the limiting block clearance groove 229, the first push rod rotation guide slope 2241 and the second push rod rotation guide slope 2242 cause the push rod 23 to rotate until the limiting block 3 abuts against the push rod rotation limiting surface 228, and the limiting block 3 is directly opposite the spacer 227; when the limiting block 3 moves from the limiting block clearance groove 229 to the lighting end 11, the third push rod rotation guide slope 2243 and the fourth push rod rotation guide slope 2244 cause the push rod 23 to rotate until the limiting block 3 is directly opposite and falls to the bottom of the adjacent limiting groove; when the limiting block 3 is at the bottom of the first limiting groove 225, the push rod 23 is at the first height position 4, and when the limiting block 3 is at the bottom of the second limiting groove 226, the push rod 23 is at the second height position 5.

[0036] Specifically, multiple limiting grooves are arranged sequentially and surround the axis of the push rod channel 221, with multiple first limiting grooves 225 and multiple second limiting grooves 226 arranged alternately. The limiting block clearance groove 229 is an annular groove that surrounds the push rod channel 221. On the side of the limiting block clearance groove 229 near the mounting end 12, multiple first push rod rotation guide inclined surfaces 2241 and multiple push rod rotation limiting surfaces 228 are provided, which are arranged alternately and surround the axis of the push rod channel 221.

[0037] The first push rod rotation guide slope 2241 faces the lighting end 11. Viewed from the lighting end 11 to the mounting end 12, the first push rod rotation guide slope 2241 gradually tilts clockwise towards the mounting end 12. The second push rod rotation guide slope 2242 faces the mounting end 12. Viewed from the mounting end 12 to the lighting end 11, the second push rod rotation guide slope 2242 gradually tilts counterclockwise towards the mounting end 12. The third push rod rotation guide slope 2243 faces the mounting end 12. Viewed from the mounting end 12 to the lighting end 11, the third push rod rotation guide slope 2243 gradually approaches the mounting end 12 clockwise. The fourth push rod rotation guide slope 2244 faces the lighting end 11. Viewed from the lighting end 11 to the mounting end 12, the fourth push rod rotation guide slope 2244 gradually tilts counterclockwise towards the mounting end 12.

[0038] The push rod rotation limiting surface 228 is an inclined surface, and the entire push rod rotation limiting surface 228 faces the lighting end 11. Viewed from the lighting end 11 to the mounting end 12, the push rod rotation limiting surface 228 is inclined counterclockwise towards the mounting end 12. Since the push rod rotation limiting surface 228 and the first push rod rotation guide inclined surface 2241 are alternately arranged, the end of the first push rod rotation guide inclined surface 2241 near the lighting end 11 and the end of the push rod rotation limiting surface 228 near the lighting end 11 will form a protruding tip. This protruding tip faces the lighting end 11, and in the direction from the mounting end 12 to the lighting end 11, the protruding tip is directly opposite the limiting groove. That is, when the limiting block 3 is in the limiting groove, the second push rod rotation guide inclined surface 2242 and the first push rod rotation guide inclined surface 2241 are only partially opposite each other.

[0039] The first height position 4 and the second height position 5 refer to the height position of the push rod 23 relative to the disassembly seat 22. When the push rod 23 is in the first height position 4, it is closer to the top of the push rod channel 221 than when the push rod 23 is in the second height position 5.

[0040] Before the lamp body 2 is installed, the top rod 23 is at the second height position 5, that is, the limiting block 3 is located at the bottom of the second limiting groove 226.

[0041] When installing the lamp body 2, the mounting bracket 22 of the lamp body 2 is first pushed into the inner side of the outer casing 1 from the lighting end 11. When the mounting bracket limiting structure 25 restricts the movement of the mounting bracket 22 towards the installation end 12, the limiting structure channel 222 is aligned with the installation groove 13. The lamp body 2 is then pushed in further, causing the push rod 23 to press against the transmission part 241. The limiting strip 24 protrudes from the outer wall of the mounting bracket 22 and is inserted into the installation groove 13. Simultaneously, the limiting block 3 moves from the second limiting groove 226 to the limiting block clearance groove 229. The second push rod rotation guide slope 2242 presses against the first push rod rotation guide slope 2241, causing the push rod 23 to rotate. Viewed from the lighting end 11 to the installation end 12, the push rod 23 rotates clockwise. Until the top rod rotation limiting surface 228 restricts the rotation of the top rod 23, the pushing force on the lamp body 2 stops. The lamp body 2 moves towards the lighting end 11 under the action of gravity. The third top rod rotation guide slope 2243 presses the fourth top rod rotation guide slope 2244, so that the top rod 23 continues to rotate clockwise until the limiting block 3 is directly opposite the adjacent first limiting groove 225. Under the action of gravity, the limiting block 3 falls to the bottom of the first limiting block 3. At this time, the top rod 23 is at the first height position 4. The top rod 23 still maintains the state of pressing the transmission part 241. The limiting strip 24 is still inserted in the mounting groove 13. The lamp body 2 is installed on the outer shell 1.

[0042] The operation of disassembling lamp body 2 is the same as the operation of installing lamp body 2. Simply push lamp body 2 and the limiting block 3 will fall into the second limiting groove 226, so that the limiting strip 24 will disengage from the mounting groove 13.

[0043] In this embodiment, the lamp body 2 is configured such that both installation and removal only require pushing the lamp body 2. With the cooperation of the limiting block 3, the limiting groove, the first push rod rotation guide slope 2241, and the third push rod rotation guide slope 2243, the push rod 23 can be switched between the first height position 4 and the second height position 5, making it more convenient to install and remove the lamp body 2.

[0044] In some specific embodiments, a top rod support spring 28 is provided in the top rod channel 221. One end of the top rod support spring 28 is connected to the top rod 23, and the other end is connected to the top of the top rod channel 221. The top rod support spring 28 can push the top rod 23 to move towards the lighting end 11.

[0045] The top rod support spring 28 helps the limit block 3 fall smoothly into the limit groove, making the disassembly and assembly process smoother and reducing the failure rate.

[0046] In some specific embodiments, the lamp body 2 is provided with a push rod receiving groove at one end near the disassembly base 22. The extension direction of the push rod receiving groove is the same as the extension direction of the outer shell 1. The push rod 23 is provided in the push rod receiving groove and can move axially and / or rotate circumferentially. A disassembly base support spring 27 is provided in the push rod receiving groove. The disassembly base support spring 27 is sleeved on the push rod 23. One end of the disassembly base support spring 27 is connected to the bottom of the push rod channel 221, and the other end is connected to the bottom of the push rod receiving groove. The disassembly base support spring 27 can push the lamp body 2 away from the disassembly base 22.

[0047] The top rod receiving groove and the mounting bracket support spring 27, together with the lamp body limiting structure 26, maintain the structural stability of the lamp body 2 before and after installation.

[0048] In some specific embodiments, the disassembly seat limiting structure 25 includes a disassembly seat limiting ring 251 disposed on the inner wall of the outer shell 1 and an annular limiting step 252 disposed on the outer wall of the disassembly seat 22.

[0049] In some specific embodiments, the lamp body limiting structure 26 includes a limiting screw 261. The mounting base 22 is provided with a screw mounting through hole, and the lamp body 2 is provided with a screw mounting screw hole corresponding to the position of the screw mounting through hole. The limiting screw 261 passes through the screw mounting through hole and is spirally connected to the screw mounting screw hole. The screw head of the limiting screw 261 is located on the side of the screw mounting through hole away from the screw mounting screw hole, and the limiting screw 261 can move axially within the screw mounting through hole.

[0050] The upper side of the disassembly base 22 is provided with a top cover 223, the lower side of the top cover 223 is provided with a locking component, and the inner side wall of the disassembly base 22 is provided with a fastening component. The top cover 223 is installed on the side wall of the disassembly base 22 through the cooperation of the locking component and the fastening component. After the top cover 223 is installed on the disassembly base 22, the part of the top cover 223 corresponding to the top rod channel 221 forms the top of the top rod channel 221.

[0051] The inner side of the mounting base 22 is provided with a mounting plate perpendicular to the top rod channel 221, and the screw mounting through hole is located on the mounting plate. When installing the mounting base 22 on the lamp body 2, the limiting screw 261 needs to be passed through the screw mounting through hole and tightened in the screw mounting screw hole, and then the top cover 223 is put on.

[0052] In some specific embodiments, the mounting base 22 is provided with a first wire hole, and the lamp body 2 is provided with a second wire hole. Wires 10 are threaded through the first wire hole and the second wire hole, and the wires 10 are communicatively connected to the lighting component 21.
