Description

Technical Field

[0001] This utility model relates to the field of panel light installation technology, and in particular to a lamp frame fixing device and an LED clean panel light. Background Technology

[0002] Panel lights are indoor lighting fixtures that use light-emitting diodes (LEDs) as their light source. The light passes through a high-transmittance light guide plate to create a uniform, planar light emission effect. Typically, the frame of a panel light is fixed to the light body with screws. This screw-fastening method can negatively impact the light fixture's cleanliness, leading to dust accumulation over time, which is difficult to wipe clean and affects the light's appearance. Furthermore, when the light source is damaged or the frame needs to be disassembled for repair, the screws must be unscrewed. This disassembly process is complex, and the screws are often small and easily lost during disassembly, making them difficult to find.

[0003] A related technology discloses a metal panel light outer ring mounting structure, including a mounting frame. A locking rod is fixedly connected inside the mounting frame. A metal panel light outer ring is placed on the top of the mounting frame. A connecting plate is fixedly connected to the bottom of the metal panel light outer ring. A locking ring is fixed to the bottom of the connecting plate and engages with the locking rod. However, long-term use of the locking ring and locking rod can cause them to loosen, increasing the gap between the metal panel light outer ring and the mounting frame. This allows external impurities to enter the metal panel light outer ring, reducing the lifespan of the light fixture and causing the metal panel light outer ring to wobble or even fall off.

[0048] Example 1

[0049] This embodiment provides an LED cleanroom panel light, such as... Figure 1 As shown, the device includes a frame unit 1, a lamp unit 2, and a lamp frame fixing device. The frame unit 1 and the lamp unit 2 are connected by the lamp frame fixing device. By setting the lamp frame fixing device, the service life of the lamp is extended, the connection between the frame unit 1 and the lamp unit 2 is made smooth, the installation error tolerance is improved, and the lamp frame fixing device can remain stable and not loose after long-term use or after other structures of the lamp unit 2 are replaced, preventing the frame unit 1 from falling off, which helps to improve the stability and safety of the lamp frame fixing device.

[0050] Optionally, such as Figure 1 As shown, the lighting unit 2 includes a lighting body 21 and an adjustment structure 23. The adjustment structure 23 is disposed on the lighting body 21 and is used to adjust the distance between the lighting body 21 and the wall. The adjustment structure 23 allows for flexible adjustment of the position of the lighting body 21 relative to the wall according to actual installation or usage needs, improving adaptability and user experience. It should be noted that in this embodiment, the lighting body 21 has a rectangular frame structure. In other embodiments, the lighting body 21 may have a circular, star-shaped, or elliptical structure, etc. No limitations are imposed here.

[0051] Optionally, such as Figure 1 As shown, the lighting unit 2 includes a lighting body 21 and a back plate structure 22, with the back plate structure 22 threadedly connected to the lighting body 21. The back plate assembly can effectively improve heat dissipation, maintain the stable operation of the lighting fixture, and achieve uniform and soft light output.

[0052] Specifically, such as Figure 1 As shown, in this embodiment, the adjustment structure 23 includes a first fixed bracket 231, an adjusting bolt 232, and a second fixed bracket 233. The first fixed bracket 231 is fixedly connected to the lamp body 21, the adjusting bolt 232 is threadedly connected to the first fixed bracket 231, and the second fixed bracket 233 is threadedly connected to the adjusting bolt 232. The second fixed bracket 233 is fixedly connected to the wall. Since the adjusting bolt 232 is threadedly connected to the first fixed bracket 231 and the second fixed bracket 233 respectively, when the adjusting bolt 232 is rotated, the distance between the first fixed bracket 231 and the second fixed bracket 233 can be changed by utilizing the advance and retreat characteristics of the thread. This adjustment function helps to adapt to the slight dimensional deviation between the lamp body 21 and the wall during installation, adjust the horizontal or verticality of the lamp body 21, ensure the aesthetics and performance after installation, and after long-term use, if the lamp body 21 becomes loose or shifts position, it can be reset and corrected by adjusting the bolt 232.

[0053] Specifically, in this embodiment, the shapes of the first fixed bracket 231 and the second fixed bracket 233 are not limited, as long as they can be connected to the adjusting bolt 232.

[0054] Optionally, such as Figure 1As shown, the frame unit 1 includes a frame body 11 and a waterproof strip 12. The waterproof strip 12 has a four-sided frame structure and is adhesively connected to the frame body 11. The waterproof strip 12 can be attached to the lamp unit 2. Due to its material properties, the waterproof strip 12 effectively prevents water, dust, and other impurities from entering the connection gap between the two when it is attached to the lamp unit 2, thus providing waterproof and dustproof protection and ensuring the normal operation and lifespan of the LED clean panel light. It should be noted that in this embodiment, the frame body 11 has a square frame structure. In other embodiments, the frame body 11 may have a circular, star-shaped, or elliptical structure, etc. No limitation is made here.

[0055] Specifically, such as Figure 1 As shown, in this embodiment, the waterproof strip 12 is made of rubber. In other embodiments, the waterproof strip 12 is made of silicone, etc. No limitation is made here.

[0056] Example 2

[0057] This embodiment provides a lamp frame fixing device, such as Figure 1 As shown, the device includes a frame unit 1, a lighting unit 2, and a fixing unit 3. The lighting unit 2 is fixedly connected to the wall. The fixing unit 3 includes a first fixing structure 31 and a second fixing structure 32. The first fixing structure 31 is fixedly and adjustablely connected to the frame unit 1, and the second fixing structure 32 is disposed on the lighting unit 2. Alternatively, the first fixing structure 31 is fixedly and adjustablely connected to the lighting unit 2, and the second fixing structure 32 is disposed on the frame unit 1. The first fixing structure 31 and the second fixing structure 32 can be connected, and the tightness of the connection between the first fixing structure 31 and the second fixing structure 32 is adjustable.

[0058] When the frame unit 1 is connected to the lamp unit 2 using the first fixing structure 31 and the second fixing structure 32, the gap between the frame unit 1 and the lamp unit 2 can be reduced or eliminated by adjusting the position of the first fixing structure 31 relative to the frame unit 1 or the lamp unit 2. This reduces the entry of external impurities, extends the lifespan of the lamp, ensures a smooth connection between the frame unit 1 and the lamp unit 2, and improves the installation tolerance. Furthermore, the tightness of the connection between the first fixing structure 31 and the second fixing structure 32 is adjustable, ensuring that the first fixing structure 31 and the second fixing structure 32 remain stable and do not loosen after long-term use or replacement of other structures of the lamp unit 2, preventing the frame unit 1 from falling off and improving the stability and safety of the lamp frame fixing device. It should be noted that the lamp body 21 is fixedly connected to the wall.

[0059] Specifically, such as Figure 1As shown, in this embodiment, the first fixing structure 31 is tunably connected to the lamp unit 2, and the second fixing structure 32 is disposed on the frame unit 1. In other embodiments, the first fixing structure 31 is tunably connected to the frame unit 1, and the second fixing structure 32 is disposed on the lamp unit 2. No limitation is made here. It should be noted that in this embodiment, the first fixing structure 31 is tunably connected to the lamp body 21, and the second fixing structure 32 is disposed on the frame body 11.

[0060] Optionally, such as Figures 1-3 As shown, the first fixing structure 31 includes a first fixing base and a first adjusting component. The first fixing base includes a first fixing body 311 and a first retaining sleeve 312. The first retaining sleeve 312 is disposed on the first fixing body 311. The first fixing body 311 is fixedly and adjustablely connected to the lamp unit 2. The first adjusting component is disposed within the first retaining sleeve 312 and can be connected to the second fixing structure 32. Through the cooperation of the first adjusting component and the second fixing structure 32, the adjustable installation of the frame body 11 and the lamp body 21 can be indirectly realized, preventing the frame unit 1 from falling off and improving the installation stability and adjustment flexibility of the frame unit 1. It should be noted that the first fixing body 311 is a fixing plate. In other embodiments, the first fixing body 311 is a fixing block or fixing piece, etc. No limitation is made here. It should be noted that the first fixing body 311 is fixedly and adjustablely connected to the lamp body 21.

[0061] Specifically, such as Figure 1 and Figure 3 As shown, in this embodiment, the first adjustment component includes a first actuator 314, a first elastic member 315, and a first adjustment member 316 installed in the first sleeve 312. The first actuator 314 can be snapped into the second fixing structure 32. One end of the first elastic member 315 abuts against the first actuator 314, and the other end of the first elastic member 315 abuts against the first adjustment member 316. The first adjustment member 316 can move along the axial direction of the first sleeve 312.

[0062] When it is necessary to increase the tightness of the connection between the first fixing structure 31 and the second fixing structure 32, the first adjusting member 316 moves along the axial direction of the first retaining sleeve 312, thereby compressing the first elastic member 315. Simultaneously, the first elastic member 315 generates elastic force, which is transmitted to the first actuating member 314. When the second fixing structure 32 engages with the first actuating member 314, because the first elastic member 315 is in a compressed state, the engagement process between the first actuating member 314 and the second fixing structure 32 requires overcoming a greater force, thus increasing the tightness of the connection between the first fixing structure 31 and the second fixing structure 32. When it is necessary to decrease the tightness of the connection between the first fixing structure 31 and the second fixing structure 32, the process is reversed. The first adjusting component enables the adjustment of the tightness of the connection between the second fixing structure 32.

[0063] Specifically, such as Figure 3 As shown, in this embodiment, the first actuator 314 is a steel ball. In other embodiments, the first actuator 314 can also be a steel column, etc. No limitation is made here.

[0064] Specifically, such as Figure 3 As shown, in this embodiment, the first elastic element 315 is a spring. In other embodiments, the first elastic element 315 can also be silicone or a leaf spring, etc. No limitation is imposed here.

[0065] Specifically, such as Figure 3 As shown, the first adjusting member 316 is threadedly connected to the first retaining sleeve 312. By screwing the first adjusting member 316, it moves axially along the first retaining sleeve 312. In other embodiments, the first adjusting member 316 is snapped into the first retaining sleeve 312, or the first adjusting member 316 is inserted into the first retaining sleeve 312, etc. No limitation is made here. It should be noted that in this embodiment, the first adjusting member 316 is a stud. In other embodiments, the first adjusting member 316 is a retaining ring, etc. No limitation is made here.

[0066] Optionally, such as Figure 3 As shown, along the axial direction of the first retaining sleeve 312, the surface where the second fixing structure 32 and the first actuating member 314 engage is an inwardly concave curved surface. This inwardly concave curved surface increases the contact area when the second fixing structure 32 and the first actuating member 314 engage, resulting in more uniform force transmission and improved connection stability and durability.

[0067] Specifically, such as Figure 2 and Figure 3As shown, the first fixing base also includes a second retaining sleeve 313 disposed on the first fixing body 311. The second retaining sleeve 313 is arranged at intervals from the first retaining sleeve 312 along the axial direction of the first retaining sleeve 312. The first fixing structure 31 also includes a second adjusting component disposed within the second retaining sleeve 313. The first adjusting component and the second adjusting component can be simultaneously connected to the second fixing structure 32. The arrangement of the second retaining sleeve 313 and the second adjusting component, together with the first retaining sleeve 312 and the first adjusting component, allows the second fixing structure 32 to be engaged and fixed from two axial directions of the first retaining sleeve 312, giving the first fixing structure 31 a dual adjustment and dual fixing function, and enabling more stable fixing of the second fixing structure 32. It should be noted that the structure of the second adjusting component is the same as that of the first adjusting component, and will not be described in detail here.

[0068] Specifically, such as Figure 3 As shown, along the axial direction of the first retaining sleeve 312, the surface where the second fixing structure 32 engages with the second adjusting component is an inwardly concave curved surface. This increases the contact area when the second fixing structure 32 and the second adjusting component engage, resulting in more uniform force transmission and improved connection stability and durability. More specifically, as... Figure 3 As shown, in this embodiment, the second fixing structure 32 is an inverted V-shaped structure. In other embodiments, the second fixing structure 32 is an oblong structure, etc. No limitations are imposed here.

[0069] Optionally, such as Figure 4 As shown, at least two fixing units 3 are provided, and at least two first fixing structures 31 are provided on two adjacent or parallel sides of the side of the lamp unit 2 facing the frame unit 1. The provision of multiple fixing units 3 disperses stress through multi-point fixing, balances the force on the lamp unit 2, further prevents the frame unit 1 from shaking or falling off, and ensures the installation stability of the frame unit 1 and the lamp unit 2.

[0070] Specifically, such as Figure 4 As shown, four fixing units 3 are provided, and four first fixing structures 31 are provided on the four sides of the four faces of the lamp body 21 opposite to the frame body 11. In other embodiments, there are two, three, or six fixing units 3, etc. There is no limitation here.

[0071] Optionally, such as Figure 4 and Figure 5As shown, the first fixing body 311 is connected to the lighting unit 2 along the radial direction of the first retaining sleeve 312 via the adjustment unit 4 to adjust the distance between the first fixing body 311 and the lighting unit 2. The first fixing body 311 is connected to the lighting unit 2 along the radial direction of the first retaining sleeve 312 via the adjustment unit 4. By operating the adjustment unit 4, the distance between the first fixing body 311 and the lighting unit 2 in this radial direction can be changed, thereby achieving fine-tuning between the frame unit 1 and the lighting unit 2, further reducing the gap between the frame unit 1 and the lighting unit 2.

[0072] Specifically, such as Figure 5 As shown, in this embodiment, the adjustment unit 4 includes an adjustment fixing member 41 and a position adjustment member 42. The adjustment fixing member 41 is fixedly connected to the lamp body 21, and the position adjustment member 42 passes through the adjustment fixing member 41 and is connected to the first fixing body 311. The position adjustment member 42 can move within the adjustment fixing member 41 along the radial direction of the first retaining sleeve 312. By moving the position adjustment member 42, the positions of the lamp body 21 and the first fixing body 311 can be changed.

[0073] Specifically, in this embodiment, the position adjustment component 42 is a bolt. In other embodiments, the position adjustment component 42 is a snap-fit ​​rod, etc. No limitation is made here.
