Description

A type of direct-lit panel light Technical Field

[0001] This utility model relates to a panel light, and more particularly to a direct-down panel light. Background Technology

[0002] Currently, panel lights on the market are mainly divided into two types: side-lit panel lights and direct-lit panel lights. Traditional direct-lit panel lights typically consist of a base frame, a diffuser plate, a decorative frame, and LED lighting devices. The diffuser plate is placed between the base frame and the decorative frame, which are fixedly connected, creating a cavity between the diffuser plate and the base frame for mounting the LED lighting devices. The decorative frame has a support wall for positioning and supporting the diffuser plate. The base frame has downward-protruding pressing ribs corresponding to the support wall positions, which press against the diffuser plate and cooperate with the support wall to fix the diffuser plate in place. For this type of direct-down panel light, ensuring a flat bottom after installation requires high precision in the manufacturing of the decorative frame's support wall and the press-fit ribs on the bottom frame. The press-fit ribs, in particular, must be perfectly aligned vertically. Any inconsistency will cause deformation of the corresponding part of the decorative frame after assembly. Further deformation during transport or installation will exacerbate this deformation. Since the decorative frame is typically aluminum and the bottom frame is usually metal, the press-fitting of the diffuser plate is a rigid connection. This rigidity means that post-installation deformation is irreversible, resulting in gaps between the light fixture and the ceiling, which detracts from the aesthetics. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a direct-down panel light with a simple structure that can effectively ensure the flatness after installation.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A direct-down panel light includes a decorative frame, a bottom frame, and a diffuser plate. The decorative frame consists of a frame-shaped decorative part, a mounting part, and a resting part, arranged sequentially from the outside to the inside. The bottom frame includes a horizontally arranged base plate. A retaining frame surrounds the side of the base plate, and a mounting frame surrounds the outer side of the retaining frame. A frame-shaped pressing part is provided on the mounting frame at a position corresponding to the resting part. The diffuser plate rests on the resting part. An elastic buffer pad is provided between the pressing part and the diffuser plate. The elastic buffer pad is disposed on the diffuser plate, and the bottom of the pressing part presses against the elastic buffer pad. The mounting frame is fixedly connected to the mounting part.

[0006] The base plate, the enclosure frame, the mounting frame, and the pressing part are an integral piece.

[0007] The elastic cushioning pad is a frame structure that mates with the press-fitting part.

[0008] The mounting frame is provided with multiple through mounting holes, and the mounting part is provided with a self-tapping groove. The mounting frame and the mounting part are fixedly connected by screws that pass through the mounting holes and are screwed into the self-tapping grooves.

[0009] The upper end face of the support portion is provided with a support rib, and the diffuser plate is disposed on the support rib.

[0010] An LED light-emitting device is provided between the bottom frame and the diffuser plate.

[0011] The base plate has multiple elongated horizontal grooves that bulge upwards, and these horizontal grooves are arranged side by side with intervals to form a concave-convex structure. The base plate also has multiple elongated vertical grooves that bulge upwards, and these vertical grooves are arranged side by side with intervals, and the vertical grooves are interlaced with the horizontal grooves.

[0012] The elastic cushioning pad is shock-absorbing cotton.

[0013] Compared with the prior art, the advantages of this utility model are: simple structure. The elastic clamping structure for installing the diffuser plate is formed by the support part, the pressing part and the elastic buffer pad. The elastic buffer pad is filled between the pressing part and the diffuser plate as an elastic medium. The compression deformation of the elastic buffer pad can absorb the assembly tolerance, reduce the manufacturing precision requirements of related parts, effectively solve the problem of poor flatness caused by dimensional or assembly force deviation, and effectively reduce the manufacturing cost. At the same time, the elastic buffer pad can be used to disperse the pressing force. Even if it is subjected to external impact, the deformation can partially rebound, thereby maintaining the overall flatness of the lamp. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] As shown in the figure, a direct-down panel light includes a decorative frame 1, a bottom frame 2, and a diffuser plate 3. The decorative frame 1 consists of a frame-shaped decorative part 11, a mounting part 12, and a resting part 13, arranged from the outside to the inside. The bottom frame 2 includes a horizontally arranged base plate 21. A retaining frame 22 is provided on the side of the base plate 21. A mounting frame 23 is provided on the outer side of the retaining frame 22. A frame-shaped pressing part 24 is provided on the mounting frame 23 at a position corresponding to the resting part 13. The diffuser plate 3 rests on the resting part 13. An elastic buffer pad 4 is provided between the pressing part 24 and the diffuser plate 3. The elastic buffer pad 4 is provided on the diffuser plate 3. The bottom of the pressing part 24 is pressed onto the elastic buffer pad 4. The mounting frame 23 is fixedly connected to the mounting part 12.

[0020] In this specific embodiment, the base plate 21, the enclosure frame 22, the mounting frame 23, and the pressing part 24 are integrated into one piece. The structure is simple and easy to manufacture.

[0021] In this specific embodiment, the elastic buffer pad 4 is a frame-shaped structure that mates with the press-fit part 24. It forms an integral module, which facilitates improved assembly efficiency.

[0022] In this specific embodiment, the mounting frame 23 is provided with multiple through mounting holes 231, and the mounting part 12 is provided with a self-tapping groove 121. A matching screw (not shown in the figure) passes through the mounting holes 231 and is screwed into the self-tapping groove 121 to achieve a fixed connection between the mounting frame 23 and the mounting part 12. The structure is simple, easy to install and disassemble, low in cost, and provides a stable connection.

[0023] In this specific embodiment, a support rib 131 is provided on the upper end face of the support portion 13, and the diffuser plate 3 is disposed on the support rib 131. The support rib 131 can increase the local rigidity of the support portion 13, prevent the frame from deforming after long-term load-bearing, thereby ensuring the support stability of the diffuser plate 3; in addition, the provision of the support rib 131 can reduce the contact area between it and the diffuser plate 3, reducing the risk of wear on the surface of the diffuser plate 3.

[0024] In this specific embodiment, an LED light-emitting device (not shown in the figure) is provided between the bottom frame 2 and the diffuser plate 3.

[0025] In this specific embodiment, the base plate 21 has multiple elongated horizontal grooves 211 protruding upwards, and these horizontal grooves 211 are arranged side by side with intervals to form a concave-convex structure. The base plate 21 also has multiple elongated vertical grooves 212 protruding upwards, and these vertical grooves 212 are arranged side by side with intervals, interleaving the horizontal grooves 211 with the vertical grooves. This structural design enhances the strength of the base plate 21, giving the base frame 2 better strength.

[0026] In this specific embodiment, the elastic cushioning pad 4 is shock-absorbing cotton. Shock-absorbing cotton is usually made of foamed polymers (such as EVA, PU, ​​EPDM), which has compressibility and resilience, can absorb impact energy and partially recover deformation, and meets the core requirements of elastic cushioning.

[0027] Flatness tests were conducted on traditional direct-lit panel lights and those with added shock-absorbing cotton between the diffuser plate and the press-fit section after assembly. The test results are as follows:

[0028]

[0029] As can be seen from the comparison, the direct-down panel light with added shock-absorbing cotton has a significantly better flatness.
