Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and more specifically, to a mounting assembly and a cleanroom lamp having the same. Background Technology

[0002] Cleanroom lights are lighting fixtures specifically designed for environments requiring high cleanliness. Their primary function is to prevent dust from entering the indoor space where they are installed. They are commonly used in hospital operating rooms, laboratories, cleanrooms, food processing plants, and similar locations. Flat panel cleanroom lights are the most common type, characterized by their simple structure, good lighting effect, and ease of cleaning. They are typically installed on ceilings or walls to provide uniform illumination to the room.

[0003] However, in the existing cleanroom lamp installation process, in order to attach and fix the cleanroom lamp body to the ceiling of the cleanroom, two installers need to hold the cleanroom lamp body from bottom to top by hand, and then another installer needs to pass screws through the holes on the cleanroom lamp frame and then use tools to fix the screws to the ceiling. Since the ceiling is high, all installers need to stand on ladders, which is time-consuming and laborious. Moreover, after fixing the cleanroom lamp to the ceiling, the installers also need to remove a ceiling module next to the cleanroom lamp to create a gap, and then enter the ceiling from the gap with their arms and upper body to connect the cleanroom lamp circuit to the power supply. The installation process is quite cumbersome.

[0004] For example, Chinese Patent Application No. 202322039472.5 discloses a novel mounting structure for a cleanroom lamp, including an outer frame. A mounting hole is provided on the lower side of the outer frame, comprising an inner hole and an outer hole. The diameter of the outer hole is larger than the diameter of the inner hole. A screw is installed within the mounting hole, and the head diameter of the screw is smaller than the diameter of the outer hole but larger than the diameter of the inner hole. This novel mounting structure allows the screw to pass through the outer hole of the outer frame and extend into the frame when fixed with a screw, as the screw head diameter is smaller than the outer hole diameter. This prevents the screw from being exposed, reducing rust and improving aesthetics, while also providing some protection to the installation environment. However, because the main body of the cleanroom lamp lacks pre-fixation, installation requires multiple people, making the process cumbersome and inefficient.

[0005] To address these issues, the present invention provides an installation assembly and a cleanroom lamp having the same. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, embodiments of the present invention provide an installation component and a cleanroom lamp having the same, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an installation component, comprising: The mounting body includes an outer cylinder in the vertical direction, and through grooves are provided on both the left and right sides of the outer cylinder. A guide cylinder in the vertical direction is provided inside the outer cylinder. The pressing part includes a sleeve that is vertically slidably connected to the guide cylinder. The upper end of the sleeve is provided with a horizontal fixing plate. The left and right sides of the fixing plate are hinged with pressing plates that pass through the through groove. The upper surface of the pressing plate can fit against the lower surface of the fixing plate. An elastic component is provided between the lower end of the pressing plate and the fixing plate. The elastic component is used for the automatic reset of the pressing plate. The sealing part includes a first sealing plate and a second sealing plate. The front and rear parts of the fixing plate are respectively hinged to two symmetrically arranged first connecting rods and two symmetrically arranged second connecting rods. The free ends of the two symmetrically arranged first connecting rods are fixedly connected to the first sealing plate, and the free ends of the two symmetrically arranged second connecting rods are fixedly connected to the second sealing plate. The drive unit drives the first and second connecting rods. When the sleeve slides up and down along the guide cylinder, the drive unit can drive the first and second connecting rods to swing up and down.

[0008] Preferably, the elastic component includes a telescopic cylinder and a telescopic rod. Both the telescopic cylinder and the telescopic rod are arc-shaped with the hinge point of the fixed plate and the lower pressure plate as the center. The ends of the telescopic cylinder and the telescopic rod that are far apart from each other are fixedly connected to the fixed plate and the lower pressure plate, respectively. The ends of the telescopic cylinder and the telescopic rod that are close to each other are slidably connected. A stop block is provided on the outside of the telescopic cylinder, and a reset member located between the stop block and the lower pressure plate is fitted on the telescopic rod.

[0009] Preferably, the driving unit includes an active component and a driven component. The active component includes a first guide rail and a second guide rail disposed inside the outer cylinder in the vertical direction. The first guide rail and the second guide rail are opposite each other front to back. A driving ring located between the first guide rail and the second guide rail is longitudinally slidably connected to the lower end of the sleeve. The upper end surface of the first guide rail and the lower end surface of the second guide rail are both inclined surfaces with the front higher than the back. When the driving ring moves downward with the sleeve, it first contacts the inclined surface of the upper end of the first guide rail and then contacts the inclined surface of the lower end of the second guide rail.

[0010] Preferably, the driven component includes a connecting gear and a rack in the front-rear direction. The connecting gear is fixedly connected to the lower end of the first connecting rod on the left side. The rack is slidably connected to the fixed plate and fixedly connected to the drive ring. The rack and the connecting gear mesh with each other. The lower ends of the first connecting rod and the second connecting rod on the right side are both provided with driven gears, and the two driven gears mesh with each other.

[0011] Preferably, a pressure spring is fitted on the guide cylinder between the upper end of the sleeve and the outer cylinder. The upper part of the guide cylinder has a through-groove. Limiting blocks are hinged to both the front and rear parts of the through-groove. The upper end of the limiting blocks is horizontal. The sleeve can be locked above the two limiting blocks. A retaining plate is provided at the upper end of the limiting block inside the guide cylinder. The width of the retaining plate is greater than the width of the through-groove.

[0012] Preferably, a push rod is slidably connected inside the guide cylinder, and an extrusion block is provided at the upper end of the push rod between the two limiting blocks. The extrusion block is narrow at the top and wide at the bottom. A limiting spring is provided between the two clamping plates, and the limiting spring always drives the upper ends of the two limiting blocks to extend out of the movable groove.

[0013] Preferably, the lower part of the guide cylinder is provided with a vertical groove, and the push rod is provided with a slider located in the groove. The slider is used to prevent the extrusion block from disengaging from the lower part of the limiting block. When the slider contacts the upper end of the groove, the upper end of the limiting block swings into the movable groove.

[0014] Preferably, the fixing plate has a housing on both the left and right sides, the rack, driven gear and connecting gear are all located inside the housing, and the housing has a clearance groove on both the front and rear sides, which provides movement space for the first connecting rod and the second connecting rod.

[0015] Preferably, the lower end of the push rod is provided with a button.

[0016] A second objective of the present invention is to provide a cleanroom lamp, comprising: The installation component is the installation component proposed in the above solution; The lamp housing has multiple mounting cylinders arranged in a rectangular array and oriented vertically at its upper end. The mounting assembly is detachably connected to the mounting cylinders. The lamp housing has multiple pressing holes corresponding to the mounting cylinders at its lower end. Sealing plugs are detachably connected to the lower ends of the pressing holes. An illumination lamp bead is disposed inside a lamp housing, and a wire is disposed on the illumination lamp bead, the wire extending from the upper end of the lamp housing; A light guide plate is disposed inside the upper part of the lamp housing. The light guide plate is designed with a dot pattern to refract the light generated by the lighting beads and change the angle of the light to achieve uniform illumination. A diffuser plate is disposed at the lower end of the interior of the lamp housing. The diffuser plate is used to evenly disperse the light from the light guide plate and to block the dots.

[0017] The technical effects and advantages of this invention are as follows: This invention features an installation assembly where a lower pressure plate retracts and passes through a mounting hole. Then, under the action of a reset component, it automatically expands and locks itself above the mounting hole, suspending the cleanroom lamp body from the ceiling. The invention also includes a limit block and a push rod. In the initial state, the lower pressure plate is confined to the upper part of the outer cylinder, ensuring sufficient space for electrical connection between the cleanroom lamp body and the ceiling when suspended. This facilitates the installation personnel connecting the cleanroom lamp's circuitry to the power supply. Finally, pressing the push rod upwards releases the restriction on the lower pressure plate, allowing the cleanroom lamp body to move upwards and close to the ceiling, maintaining the cleanliness of the cleanroom. The entire installation process eliminates the need for other installers to lift the cleanroom lamp; only one installer is required. Compared to the current screw-fixing method, this saves time and effort, improves the efficiency of cleanroom lamp installation, and facilitates subsequent maintenance.

[0018] This invention utilizes a first and second guide rail. When the sleeve moves downward under the action of a pressure spring, the inclined surface at the upper end of the first guide rail presses the drive ring backward. The drive ring causes the first and second sealing plates to swing downward, expanding them to the outside of the outer cylinder and fitting against its outer surface. Combined with two lower pressure plates, this blocks the gap between the mounting hole and the outer cylinder from above, preventing dust from the ceiling from entering the gap and helping to maintain the cleanliness of the cleanroom. When the sleeve moves upward, the inclined surface at the lower end of the second guide rail presses the drive ring forward, causing it to swing upward and retract to the top of the outer cylinder. At this point, the first and second sealing plates can pass through the mounting hole in the ceiling, facilitating the removal of the cleanroom light from the ceiling for maintenance.

[0019] This invention features a press hole and a sealing plug. When in use, the sealing plug can be removed, allowing the installer to operate the button inside the press hole. The press hole provides space for the button to move up and down. After the sealing plug is reinserted into the press hole, the lower end of the cleanroom lamp will be flatter and more aesthetically pleasing, and dust can be prevented from entering the lamp.

[0020] The invention provides a protective shell for the rack, driven gear, and connecting gear, preventing external objects from entering the shell and affecting the normal operation of the linkage components. The clearance groove on the shell provides space for the first and second connecting rods to move. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1 During actual installation, it was found that in order to fit the main body of the cleanroom lamp against the ceiling of the cleanroom, two installers needed to hold the main body of the cleanroom lamp from bottom to top by hand, and then another installer needed to pass screws through the holes on the cleanroom lamp frame and then use tools to fix the screws to the ceiling. Because the ceiling was high, all installers needed to stand on a ladder, which was time-consuming and laborious. Moreover, after fixing the cleanroom lamp to the ceiling, the installers also needed to remove a piece of the ceiling next to the cleanroom lamp and then reach their arms and upper bodies into the ceiling to connect the cleanroom lamp's circuit to the power supply. The installation process was quite cumbersome. To solve the above problems, this embodiment was invented.

[0034] Please see Figure 1 As shown, the present invention proposes an installation component, which includes an installation body 1, a pressing part 2, a sealing part 3, and a driving part 4.

[0035] It should be noted that the mounting components in this embodiment are mainly used for cleanroom lamps.

[0036] Please see Figure 3As shown, the mounting body 1 includes an outer cylinder 101 in the vertical direction, with through grooves 102 on both the left and right sides of the outer cylinder 101. A guide cylinder 103 in the vertical direction is provided inside the outer cylinder 101. The pressing part 2 includes a sleeve 201 that is vertically slidably connected to the guide cylinder 103. A horizontal fixing plate 202 is provided at the upper end of the sleeve 201. A pressing plate 203 passing through the through grooves 102 is hinged to both the left and right sides of the fixing plate 202. The upper surface of the pressing plate 203 can fit against the lower surface of the fixing plate 202. An elastic component 204 is provided between the lower end of the pressing plate 203 and the fixing plate 202. The elastic component 204 is used for the automatic retraction of the pressing plate 203. The sealing part 3 includes a first sealing plate 301 and a second sealing plate 302. The front and rear parts of the fixing plate 202 are respectively hinged with two symmetrically arranged first connecting rods 303 and two symmetrically arranged second connecting rods 304. The free ends of the two symmetrically arranged first connecting rods 303 are fixedly connected to the first sealing plate 301, and the free ends of the two symmetrically arranged second connecting rods 304 are fixedly connected to the second sealing plate 302. The first connecting rods 303 and the second connecting rods 304 are driven by the driving part 4. When the sleeve 201 slides up and down along the guide cylinder 103, the driving part 4 can drive the first connecting rods 303 and the second connecting rods 304 to swing up and down.

[0037] Please see Figure 4 As shown, the elastic component 204 includes a telescopic cylinder 2041 and a telescopic rod 2042. Both the telescopic cylinder 2041 and the telescopic rod 2042 are arc-shaped with the hinge point of the fixed plate 202 and the lower pressure plate 203 as the center. The ends of the telescopic cylinder 2041 and the telescopic rod 2042 that are far apart from each other are fixedly connected to the fixed plate 202 and the lower pressure plate 203, respectively. The ends of the telescopic cylinder 2041 and the telescopic rod 2042 that are close to each other are slidably connected. A stop block 2043 is provided on the outside of the telescopic cylinder 2041. A reset member 2044 located between the stop block 2043 and the lower pressure plate 203 is fitted on the telescopic rod 2042.

[0038] Please see Figure 5As shown, a pressure spring 5 is fitted onto the guide cylinder 103 between the upper ends of the sleeve 201 and the outer cylinder 101. A through-hole swivel groove 1031 is formed on the upper part of the guide cylinder 103. Limiting blocks 1032 are hinged to both the front and rear ends of the swivel groove 1031. The upper ends of the limiting blocks 1032 are horizontal, allowing the sleeve 201 to be locked above the two limiting blocks 1032. A retaining plate 1033 is located inside the guide cylinder 103 at the upper end of the limiting blocks 1032. The width of the retaining plate 1033 is greater than the width of the swivel groove 1031. A push rod 1034 is slidably connected inside the guide cylinder 103. The upper end of the push rod 1034 is located between the two limiting blocks. The extrusion block 1035 between the two plates 1032 is narrow at the top and wide at the bottom. A limiting spring 1036 is provided between the two plates 1033. The limiting spring 1036 always drives the upper end of the two limiting blocks 1032 to extend out of the movable groove 1031. The guide cylinder 103 has a vertical sliding groove 1037 at the bottom. The push rod 1034 has a slider 1038 located in the sliding groove 1037 outside. The slider 1038 is used to prevent the extrusion block 1035 from disengaging from the lower part of the limiting block 1032. When the slider 1038 contacts the upper end of the sliding groove 1037, the upper end of the limiting block 1032 swings into the movable groove 1031.

[0039] In use, in the initial state, multiple mounting bodies 1 are arranged in a rectangular array on the upper part of the cleanroom lamp. Each pressing part 2 is located on the upper part of the outer cylinder 101, and the pressing plate 203 is located on the upper part of the through groove 102. The sleeve 201 in the pressing part 2 is stuck above two symmetrically distributed limiting blocks 1032. At this time, the sleeve 201 cannot slide down along the guide cylinder 103.

[0040] The installer needs to first measure the distance between every two mounting bodies 1, and then drill mounting holes on the ceiling corresponding to the multiple mounting bodies 1. The diameter of the mounting holes needs to be slightly larger than the diameter of the outer cylinder 101 to facilitate the insertion of the outer cylinder 101 into the mounting holes. The installer can lift the cleanroom lamp with multiple bodies upward by one person, so that each mounting body 1 is inserted into the corresponding mounting hole from bottom to top. The mounting body 1 drives the pressure plate 203 in the pressure part 2 to move upward.

[0041] When the two pressure plates 203 on both sides contact the ceiling, the overall width of the two pressure plates 203 is greater than the diameter of the mounting hole, forcing the two symmetrically arranged pressure plates 203 to swing downward together. The pressure plates 203 drive the elastic component 204 to contract, that is, the pressure plates 203 drive the telescopic rod 2042 to swing downward around the hinge point. Since both the telescopic rod 2042 and the telescopic cylinder 2041 are arc-shaped with the hinge point of the pressure plate 203 as the center, the telescopic rod 2042 gradually inserts into the telescopic cylinder 2041. At the same time, the pressure plates 203 begin to squeeze the reset piece 2044 between the pressure plate 2043 and the stop block 2043. The reset piece 2044 is a spring. The telescopic rod 2042 and the telescopic cylinder 2041 provide guidance for the extension and retraction of the reset piece 2044.

[0042] When both lower pressure plates 203 swing downwards into the through slot 102, the distance between the two lower pressure plates 203 is less than the diameter of the mounting hole. The two lower pressure plates 203 move upwards with the outer cylinder 101 and enter the mounting hole. After the lower pressure plates 203 move out of the mounting hole, they reach above the ceiling. After the reset member 2044 loses the pressure of the lower pressure plates 203, it begins to return to its original length. The reset member 2044 drives the lower pressure plates 203 to swing upwards. The lower pressure plates 203 drive the telescopic rod 2042 to gradually extend out of the telescopic cylinder 2041. When the lower pressure plates 203 move downwards... When the lamp swings upward to the horizontal position, the upper end face of the lower pressure plate 203 contacts the lower end face of the fixing plate 202. The fixing plate 202 prevents the lower pressure plate 203 from swinging upward further. At this time, the distance between the two lower pressure plates 203 is greater than the diameter of the mounting hole. The installer can release the cleanroom lamp, and multiple lower pressure plates 203 are all stuck above the mounting hole. The multiple lower pressure plates 203 suspend the cleanroom lamp on the ceiling. At this time, there is a certain space between the cleanroom lamp and the ceiling. The installer can connect the power supply to the cleanroom lamp circuit in this space. During this process, the installer does not need to lift the cleanroom lamp upward.

[0043] After the circuit connection is completed, the installer first presses up the two push rods 1034 at one of the opposite corners of the cleanroom lamp. The push rods 1034 drive the two sliders 1038 to slide upwards within the slide groove 1037. The sliders 1038 and the slide groove 1037 are designed to prevent the push rods 1034 from rotating within the guide cylinder 103. The push rods 1034 drive the extrusion block 1035 to move upwards. Since the extrusion block 1035 is located between two symmetrically arranged limit blocks 1032, and the extrusion... Block 1035 is narrower at the top and wider at the bottom. When the pressing block 1035 moves upward, it will cause the lower ends of the two limiting blocks 1032 to gradually separate, while the upper ends of the two limiting blocks 1032 will gradually move closer. The two limiting blocks 1032 will cause the two clamping plates 1033 to move closer to each other. The two clamping plates 1033 will start to press the limiting spring 1036. The upper end of the limiting block 1032 will gradually enter the movable groove 1031, and the contact area between the upper end of the limiting block 1032 and the lower end face of the sleeve 201 will gradually decrease.

[0044] When the upper end of the limiting block 1032 is fully inserted into the movable groove 1031, the upper end of the limiting block 1032 separates from the sleeve 201, releasing the limiting effect on the sleeve 201. The pressure spring 5 then drives the sleeve 201 to slide downward along the guide cylinder 103. The sleeve 201 drives the two symmetrically arranged lower pressure plates 203 to move downward. The distance between the two lower pressure plates 203 and the cleanroom lamp body gradually decreases. Because the lower pressure plates 203 are stuck by the mounting holes on the ceiling and cannot move downward, the reaction force... The main body of the cleanroom lamp is moved upward and close to the ceiling. The push rod 1034 is released, and the two clamping plates 1033 gradually separate under the action of the limiting spring 1036. The two clamping plates 1033 drive the upper ends of the two limiting blocks 1032 to extend out of the movable groove 1031. The width of the clamping plate 1033 is smaller than the width of the movable groove 1031, which can keep the upper end of the limiting block 1032 horizontal. The two limiting blocks 1032 drive the squeezing block 1035 and the push rod 1034 to move downward to the initial position.

[0045] When the main body of the cleanroom lamp is in contact with the lower end of the ceiling, press the two symmetrical push rods 1034 upwards in sequence to release the limiting position of the sleeves 201 in other positions, so that the lower pressure plates 203 in multiple positions are in contact with the upper end of the ceiling, making the cleanroom lamp more secure.

[0046] Example 2 In actual use, it was found that because the diameter of the mounting hole on the ceiling is slightly larger than the diameter of the outer cylinder 101, there is a gap between the outer cylinder 101 and the mounting hole after the cleanroom lamp is installed. Dust from the ceiling can easily enter the mounting hole and fall directly into the cleanroom when the cleanroom lamp is disassembled and repaired, which will have a certain impact on the cleanroom environment. Therefore, further improvements have been made based on the above embodiment.

[0047] Please see Figure 8 As shown, the drive unit 4 includes an active component 401 and a driven component 402. The active component 401 includes a first guide rail 4011 and a second guide rail 4012 disposed inside the outer cylinder 101 in the vertical direction. The first guide rail 4011 and the second guide rail 4012 are opposite each other. A drive ring 4013 located between the first guide rail 4011 and the second guide rail 4012 is longitudinally slidably connected to the lower end of the sleeve 201. The upper end surface of the first guide rail 4011 and the lower end surface of the second guide rail 4012 are both inclined surfaces with the front higher than the back. When the drive ring 4013 moves downward with the sleeve 201, it first contacts the inclined surface of the upper end of the first guide rail 4011 and then contacts the inclined surface of the lower end of the second guide rail 4012.

[0048] Please see Figure 7As shown, the driven component 402 includes a connecting gear 4021 and a rack 4022 in the front-rear direction. The connecting gear 4021 is fixedly connected to the lower end of the first connecting rod 303 on the left side. The rack 4022 is slidably connected to the fixed plate 202 and fixedly connected to the drive ring 4013. The rack 4022 and the connecting gear 4021 mesh with each other. The lower ends of the first connecting rod 303 and the second connecting rod 304 on the right side are both provided with driven gears 4023, and the two driven gears 4023 mesh with each other.

[0049] Please see Figure 6 As shown, the fixed plate 202 has a housing 6 on both the left and right sides. The rack 4022, driven gear 4023 and connecting gear 4021 are all located inside the housing 6. The housing 6 has a clearance groove 7 on both the front and rear sides. The clearance groove 7 is used to provide movement space for the first connecting rod 303 and the second connecting rod 304.

[0050] Based on the above embodiments, during use, when the installer presses the push rod 1034 upwards, the two limit blocks 1032 release the limit on the sleeve 201, and the pressure spring 5 drives the sleeve 201 to slide downwards along the guide cylinder 103. When the sleeve 201 moves downwards, the fixing plate 202 at the upper end of the sleeve 201 will drive the sealing part 3 to move downwards. At the same time, the sleeve 201 drives the drive ring 4013 in the active component 401 to move downwards. In the initial state, the drive ring 4013 is in contact with the upper part of the second guide rail 4012. When the drive ring 4013 moves downwards, it will not move in the front and back directions.

[0051] When the drive ring 4013 contacts the inclined surface at the upper end of the first guide rail 4011, since the inclined surface at the upper end of the first guide rail 4011 is higher in the front and lower in the back, the inclined surface at the upper end of the first guide rail 4011 presses the drive ring 4013 backward, causing the drive ring 4013 to move backward on the sleeve 201. The drive ring 4013 drives the rack 4022 to move backward, and the rack 4022 drives the connecting gear 4021 meshing with it to rotate clockwise. The connecting gear 4021 drives the first connecting rod 303 to swing downward, and the first connecting rod 303 drives the first sealing plate 30 1. The first connecting rod 303 swings downward, and at the same time, the first connecting rod 303 drives the two meshing driven gears 4023 to rotate. The driven gears 4023 drive the second connecting rod 304 to swing downward in sync. The second connecting rod 304 drives the second sealing plate 302 to swing downward. The outer shell 6 can provide good protection for the rack 4022, the driven gears 4023 and the connecting gears 4021, and prevent external objects from entering the interior of the outer shell 6 and affecting the normal use of the components. The clearance groove 7 opened on the outer shell 6 provides room for the first connecting rod 303 and the second connecting rod 304 to move.

[0052] When the drive ring 4013 disengages from the inclined surface at the upper end of the first guide rail 4011, both the first sealing plate 301 and the second sealing plate 302 swing to the horizontal direction. Both the first sealing plate 301 and the second sealing plate 302 are in contact with the outer surface of the outer cylinder 101 and are in the same plane as the two symmetrically arranged lower pressure plates 203. When the lower pressure plate 203 contacts the ceiling, the lower ends of the first sealing plate 301 and the second sealing plate 302 are in contact with the upper surface of the ceiling. Together with the two lower pressure plates 203, they block the gap between the mounting hole and the outer cylinder 101, thereby preventing dust from the ceiling from entering the mounting hole.

[0053] Example 3 In actual use, it was found that the push rod 1034 is slidably connected to the cleanroom lamp body. In order to facilitate the installer to press the push rod 1034 upward, the lower end of the push rod 1034 needs to extend out of the cleanroom lamp body, making the lower end of the cleanroom lamp body look very unsightly. Further improvements have been made based on the above embodiment.

[0054] Please see Figure 3 and Figure 4 As shown, a button 8 is provided at the lower end of the push rod 1034.

[0055] Please see Figure 10 and Figure 11 As shown, a cleanroom lamp includes a mounting assembly, which is the mounting assembly proposed in the above-described scheme; a lamp housing 100, with multiple mounting cylinders 200 arranged in a rectangular array and oriented vertically on the upper end of the lamp housing 100, the mounting assembly being detachably connected to the mounting cylinders 200; multiple pressing holes 300 corresponding one-to-one with the mounting cylinders 200 on the lower end of the lamp housing 100, and sealing plugs 400 being detachably connected to the lower end of the pressing holes 300; lighting beads 500 disposed inside the lamp housing 100, with wires disposed on the lighting beads 500, the wires extending from the upper end of the lamp housing 100; a light guide plate 600 disposed inside the upper end of the lamp housing 100, the light guide plate 600 being used to refract and change the angle of light generated by the lighting beads 500 through a dotted pattern design to achieve uniform illumination; and a diffuser plate 700 disposed inside the lower end of the lamp housing 100, the diffuser plate 700 being used to uniformly diffuse the light from the light guide plate 600 and to block the dots.

[0056] It should be noted that after the mounting components are fixed to the mounting cylinder 200, the button 8 in the mounting components is located inside the pressing hole 300. The lighting beads 500, light guide plate 600 and diffuser plate 700 are all existing technologies and will not be described in detail here.

[0057] Based on the above embodiments, during use, the mounting assembly needs to be fixed to the mounting cylinder 200 first. This can be done by using a threaded connection, thereby fixing the mounting assembly to the lamp housing 100. Then, the sealing plug 400 in each pressing hole 300 is pulled out. The push rod 1034 can be moved up and down simply by operating the button 8 in the pressing hole 300. The pressing hole 300 provides space for the up and down movement of the push rod 1034 and the button 8, so that the lower end of the push rod 1034 does not protrude from the lamp housing 100. After the lamp housing 100 is installed on the ceiling, the installer needs to insert multiple sealing plugs 400 into the lower part of multiple pressing holes 300 in sequence, so that the lower end of the lamp housing 100 is flatter and more aesthetically pleasing, while preventing dust from entering the pressing hole 300.

[0058] After the power switch is turned on, the lighting lamp 500 is connected to the power supply through the wire and starts to emit light. The light guide plate 600 refracts the light generated by the lighting lamp 500, changes the angle of the light and disperses it. The diffuser plate 700 then disperses the light from the light guide plate 600 evenly, thereby achieving uniform lighting.

[0059] In summary, by setting up a downward-swinging pressure plate 203, the pressure plate 203 can pass through the mounting hole and be secured above it, thus suspending the cleanroom lamp body from the ceiling. The limiting block 1032 and push rod 1034 restrict the pressure part 2 to the upper part of the outer cylinder 101, ensuring sufficient space for electrical connection between the cleanroom lamp body and the ceiling after suspension. This facilitates the installer connecting the cleanroom lamp's circuitry to the power supply. Pressing the push rod 1034 upwards releases the restriction on the pressure part 2, bringing the cleanroom lamp body close to the ceiling and maintaining the cleanliness of the cleanroom. The entire installation process is seamless. Other installers are required to lift the cleanroom lamp upwards, allowing one installer to complete the installation. Compared to the current screw fixing method, this method is not only time-saving and labor-saving, but also facilitates subsequent maintenance. The first sealing plate 301 and the second sealing plate 302 allow the sleeve 201 to automatically swing downwards when it moves downwards. While fixing the cleanroom lamp, the two pressure plates 203 can block the gap between the mounting hole and the outer cylinder 101, preventing dust from the ceiling from entering the gap and helping to ensure the cleanliness of the cleanroom. The pressing hole 300 and the sealing plug 400 make the lower end of the cleanroom lamp flatter and more aesthetically pleasing.
