Description

Technical Field

[0001] This application relates to the field of lighting technology, specifically to a cleanroom panel light. Background Technology

[0002] Cleanrooms are enclosed spaces that control parameters such as airborne dust, temperature, humidity, and pressure within a specific range. They are widely used in high-precision fields such as semiconductors and pharmaceuticals. According to ISO standards, they are divided into different cleanliness levels and rely on high-efficiency filtration and stable airflow organization. The lighting fixtures inside must meet the requirements of having no dead corners, not generating pollutants, being easy to clean, not interfering with airflow, and being suitable for the space. They also have characteristics such as explosion protection, electrical safety, uniform illumination without glare, durability, and stability. They mostly use recessed or ceiling-mounted LED lights to ensure that they provide qualified lighting without affecting the clean environment.

[0003] In related technologies, direct-down panel lights in cleanrooms are installed on the ceiling. When replacement is needed, it is very inconvenient for maintenance personnel to disassemble them. They must open the interlayer, which is time-consuming and laborious. Moreover, opening the interlayer can easily bring dust and bacteria from the ceiling into the cleanroom, which has a significant impact on the cleanroom environment.

[0046] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0047] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0049] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0050] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0051] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0052] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0053] like Figures 1 to 3 As shown, this application provides a cleanroom panel light, which includes a lamp housing module 1, a back panel module 2, and a panel module 3. The lamp housing module 1 includes a lamp housing 11 and a mounting assembly 12. The lamp housing 11 has an installation space and an installation port 110 communicating with the installation space. The mounting assembly 12 is used to install the lamp housing 11 onto the ceiling 100. The back panel module 2 includes a back panel 21 and a lamp assembly 22 installed on the back panel 21. The back panel 21 can be inserted into the installation space through the installation port 110 and is detachably installed on the lamp housing 11. The panel module 3 includes a frame 31 and a panel 32. The frame 31 has a light-transmitting opening 311. The panel 32 is installed on the frame 31 and covers the light-transmitting opening 311. The frame 31 is detachably installed on the lamp housing 11 and covers the installation port 110 along a direction perpendicular to the surface of the frame 31. The cleanroom panel light consists of a lamp housing module 1, a back panel module 2, and a panel module 3, enabling modular assembly. During subsequent maintenance, the panel module 3 and the back panel module 2 can be disassembled from the front of the light without opening the interlayer, facilitating maintenance and ensuring that the cleanroom environment is not affected.

[0054] The mounting assembly 12 includes an adjusting bolt 121 and a pressure plate 122. The adjusting bolt 121 is fixed to the outer wall of the lamp housing 11 by a bracket, and the pressure plate 122 is threadedly connected to the adjusting bolt 121. When installing the cleanroom panel light, first rotate the pressure plate 122 to the side closer to the lamp housing 11, then insert the lamp housing 11 into the mounting groove of the ceiling 100. Then, rotating the adjusting bolt 121 will cause the pressure plate 122 to rotate synchronously until it abuts against the top wall of the ceiling 100, thereby hanging the panel light on the ceiling 100. After that, continuing to rotate the adjusting bolt 121 will cause the pressure plate 122 to move downward relative to the lamp housing 11 until the pressure plate 122 and the frame 31 clamp the ceiling 100, thus fixing the panel light and preventing the panel light from shaking.

[0055] To achieve detachable installation of the frame 31 and the lamp housing 11, such as Figures 4 to 6As shown, the cleanroom panel light also includes a snap-fit ​​module, which includes a limiting component 41 and an elastic buckle component 42 that is detachably snap-fitted to the limiting component 41. One set of the limiting component 41 and the elastic buckle component 42 is fixed to the inner wall of the lamp housing 11, and the other set is fixed to the frame 31.

[0056] In one embodiment, the limiting component 41 includes a first limiting member 411 and a second limiting member 412 spaced apart from the first limiting member 411, forming a limiting interval between the second limiting member 412 and the first limiting member 411; the elastic buckle component 42 includes a first elastic buckle 421 and a second elastic buckle 422, wherein the maximum distance after the elastic deformation ends of the first elastic buckle 421 and the second elastic buckle 422 are less than the width of the limiting interval, and the maximum distance before the elastic deformation ends of the first elastic buckle 421 and the second elastic buckle 422 are greater than the width of the limiting interval, so that the first elastic buckle 421 engages with the first limiting member 411, and the second elastic buckle 422 engages with the second limiting member 412.

[0057] In one embodiment, the first limiting member 411 and the second limiting member 412 each include a fixing part 4101, a limiting part 4102 and a first guiding part 4103 connected in sequence. The fixing part 4101 is fixed to the inner wall of the lamp housing 11. The limiting part 4102 extends away from the fixing part 4101 and the angle between it and the fixing part 4101 is not less than 90°. The first guiding part 4103 extends towards the fixing part 4101 and the angle between it and the limiting part 4102 is less than 90°. The first elastic buckle 421 and the second elastic buckle 422 both include a connecting part 4201, an extension part 4202, a snap-fit ​​part 4203, and a second guide part 4204 connected in sequence. The connecting part 4201 is fixed to the frame 31. The extension part 4202 extends in a direction away from the frame 31. The extension part 4202, the snap-fit ​​part 4203, and the second guide part 4204 form an elastically deformable end. The snap-fit ​​part 4203 can press against the upper part of the limiting part 4102. The second guide part 4204 can cooperate with the first guide part 4103 to change the included angle between the extension part 4202 and the connecting part 4201.

[0058] During the installation of panel module 3, as the worker pushes the frame 31 upwards, the first elastic buckle 421 and the second elastic buckle 422 on the frame 31 deform and move closer to each other under the action of the first limiting member 411 and the second limiting member 412, respectively. When the worker continues to push the frame 31 upwards, the first elastic buckle 421 and the second elastic buckle 422 deform and reset after passing the first limiting member 411 and the second limiting member 412. At this time, when the worker releases the frame 31, the frame 31 can descend under its own weight, so that the first elastic buckle 421 is locked on the first limiting member 411 and the second elastic buckle 422 is locked on the second limiting member 412.

[0059] In one embodiment, the height of the lamp housing 11 can be 100mm, which is suitable for most ceiling heights of 100mm, and the internal installation space of the lamp housing 11 is large enough to facilitate the installation of the back panel module 2 and power supply components. The lamp housing 11 is made of 0.6mm thick cold-rolled steel plate. Cold-rolled steel plate has significantly improved strength and hardness, and good ductility and toughness, making it suitable for cold working such as stamping and bending; the material is uniform, the mechanical properties are stable, and it is not easy to crack or deform during processing, resulting in a high yield and ensuring the strength of the lamp housing 11. A sandwich layer is formed between the back panel 21 and the lamp housing 11 to house the power supply, preventing external interference to the power supply. The lamp housing 11 is also designed with a breather valve to balance pressure and prevent condensation. In addition, the large internal space of the lamp housing 11 is sufficient to ensure heat dissipation.

[0060] Continue as Figure 6 As shown, a first sealing element 71 is provided between the frame 31 and the lamp housing 11. This first sealing element 71 achieves a sealed fit between the frame 31 and the lamp housing 11, preventing dust and water from entering the cleanroom panel light. A second sealing element 72 is provided between the frame 31 and the panel 32. This second sealing element 72 achieves a sealed fit between the frame 31 and the panel 32, preventing dust and water from entering the cleanroom panel light. A third sealing element 73 is provided between the frame 31 and the ceiling 100. This third sealing element 73 achieves a sealed installation of the cleanroom panel light and improves its stability.

[0061] In one embodiment, the first sealing element 71, the second sealing element 72, and the third sealing element 73 can all be made of rubber gaskets. Rubber gaskets, with their excellent elasticity and plasticity, can tightly conform to the sealing surface, effectively filling minor imperfections to prevent fluid leakage, resulting in outstanding sealing performance. They have a wide temperature range, adapting to environments from -60℃ to above 300℃, meeting the needs of high and low temperature scenarios. Specific materials exhibit strong resistance to oils, acids, alkalis, and other chemicals, enabling stable operation in corrosive environments. They also provide shock absorption and cushioning, reducing component wear and extending equipment lifespan. Furthermore, they are low-cost and easily manufactured into various shapes through molding, extrusion, and other processes to adapt to different sealing structures.

[0062] In one embodiment, the first sealing element 71 is a waterproof adhesive strip, ensuring a seamless connection between the frame 31 and the lamp housing 11, achieving a waterproof rating of IP65. In another embodiment, the second sealing element 72 is made of thermally conductive silicone, ensuring a tight contact between the frame 31 and the panel 32, improving the sealing rating while facilitating heat conduction between the back panel 21 and the frame 31. In yet another embodiment, the third sealing element 73 is a foamed silicone strip, ensuring a seamless contact between the ceiling 100 and the frame 31, achieving a dustproof effect.

[0063] To further improve the installation stability of frame 31, such as Figure 7 As shown, the cleanroom panel light also includes fastening components 5. At least two fastening components 5 are arranged circumferentially along the frame 31. Each fastening component 5 includes a first fastener 51 and a second fastener 52. The first fastener 51 has a threaded hole 511, and the second fastener 52 can be threadedly connected to the threaded hole 511. The first fastener 51 is fixed to the lamp housing 11 and located outside the installation space. The frame 31 has a first hole 312 through which the second fastener 52 passes.

[0064] In one embodiment, the fastening assembly 5 further includes a rubber pad 53, which is fixed to the frame 31. The rubber pad 53 has a second hole 531 corresponding to and communicating with the first hole 312, and the second fastener 52 is interference-fitted with the second hole 531. With this design, when disassembling the second fastener 52, the rubber pad 53 prevents the second fastener 52 from falling off the frame 31 after it separates from the first fastener 51, freeing up the worker's hands. There is no need for the worker to collect the second fastener 52; during reassembly, the corresponding second fastener 52 simply needs to be tightened again. It is understood that the second fastener 52 can be a capped bolt.

[0065] To enable the detachable assembly of the backplate 21 and the lamp housing 11, such as Figure 8 As shown, the inner wall of the lamp housing 11 is provided with a disassembly screw 111, and the back plate 21 has a disassembly opening 211 that mates with the disassembly screw 111. The disassembly opening 211 is gourd-shaped. Therefore, the nut of the disassembly screw 111 can be passed through the large opening of the disassembly opening 211 first, and then the position of the back plate 21 can be adjusted so that the nut of the disassembly screw 111 is locked at the small opening of the disassembly opening 211. In this way, the back plate 21 can be disassembled and secured to the lamp housing 11.

[0066] To improve the safety of disassembly, assembly, and maintenance operations, such as Figures 8 to 10 As shown, the cleanroom panel light also includes an anti-fall component 6, which includes a safety rope 61 and a buckle 62. The first end of the safety rope 61 has a locking buckle 611 that can be detachably fastened to the buckle 62. The anti-fall component 6 is connected between the lamp housing 11 and the frame 31, and between the lamp housing 11 and the back panel 21, to prevent accidental drops during the disassembly and assembly of the back panel module 2 and the panel module 3. In one embodiment, the safety rope 61 can be a telescopic rope, which can reduce the duty cycle of the safety rope 61 when there is no external force, and reduce the impact of the safety rope 61 on the light.

[0067] In this embodiment, the longitudinal cross-sectional shape of the back plate 21 is approximately trapezoidal, and the design of the beveled edges around the edges makes the light emission more uniform. A handle is designed in the middle of the back plate 21. Since the height of the handle cannot be designed too high to avoid affecting the light emission effect, a spring is provided at the position of the handle to allow the height of the handle to extend or retract, preventing interference with the light emission effect.

[0068] In this embodiment, a buckle 62 is installed on the frame 31, and a safety rope 61 that cooperates with the buckle 62 is installed on the lamp housing 11. The second end of the safety rope 61 is fixedly connected to the lamp housing 11, thereby achieving a safe connection between the frame 31 and the lamp housing 11. Similarly, a buckle 62 is installed on the back plate 21, and a safety rope 61 that cooperates with the buckle 62 is installed on the lamp housing 11. The second end of the safety rope 61 is fixedly connected to the lamp housing 11, thereby achieving a safe connection between the back plate 21 and the lamp housing 11.

[0069] In one embodiment, the anti-drop component 6 between the lamp housing 11 and the frame 31 and the anti-drop component 6 between the lamp housing 11 and the back plate 21 are respectively located on both sides of the lamp housing 11 to avoid interference and collision between the back plate 21 and the frame 31 when they are disassembled and suspended.

[0070] In summary, the cleanroom panel light provided in this application is a front-opening recessed panel light, which can be recessed by the mounting component 12; the frame 31 can be detachably installed on the lamp housing 11 from the front by the snap-fit ​​module and fastening component 5; the back plate 21 can be detachably installed on the lamp housing 11 from the front by the disassembly port 211 of the back plate 21 and the disassembly screws 111 of the lamp housing 11; and the anti-fall component 6 can improve the safety during disassembly, assembly and maintenance.

[0071] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
