[0034] The technical scheme of the present application will be further illustrated by the specific embodiments below. Figures 1 to 6 The technical scheme of the present application will be further illustrated by the specific embodiments below.

[0035] A screw-free narrow-frame side-lighting panel lamp, comprising a frame 1, a back plate 2, a light bar 3 and a lamp panel assembly 4;

[0036] The frame 1 comprises a horizontal supporting bottom plate 11, a vertical side plate 12 and a vertical limiting plate 13, the vertical side plate 12 and the vertical limiting plate 13 are arranged on the top surface of the horizontal supporting bottom plate 11 in parallel with each other, the horizontal supporting bottom plate 11, the vertical side plate 12 and the vertical limiting plate 13 form a clamping part 101 with an open top, the edge of the back plate 2 is clamped and installed in the clamping part 101, the part of the horizontal supporting bottom plate 11 away from the clamping part 101 is a supporting part 102, and the supporting part 102 is used for accommodating the lamp panel assembly 4;

[0037] The light bar 3 is installed on the side of the vertical limiting plate 13 away from the vertical side plate 12, the light-emitting surface of the light bar faces the outer peripheral side surface of the lamp panel assembly 4, the top surface of the lamp panel assembly 4 abuts against the back plate 2, and the bottom surface of the lamp panel assembly 4 abuts against the horizontal supporting bottom plate 11.

[0038] The back plate 2 is installed and fixed on the frame 1 in a clamping mode, avoiding the traditional screw locking mode, completely solving the problem of screw head exposed on the surface of the back plate 2, making the appearance of the lamp simple and flat, and reducing the gap caused by the screw hole and enhancing the overall sealing. The back plate 2 and the frame 1 are quickly installed through the clamping structure, without the need to tighten the screws one by one, significantly reducing the assembly steps and manual operation time, improving production efficiency, and reducing labor and time costs. In addition, due to the reduction of the use of screws and other parts, the material cost is also further reduced. Further, in the traditional side light panel lamp, in order to avoid interference between the screw hole and the frame edge, sufficient space needs to be reserved in the frame, which leads to a large proportion of the frame on the front of the panel lamp, reducing the effective light emitting area. The frame 1 is designed into a compact clamping part 101 formed by a horizontal support bottom plate 11, a vertical side plate 12 and a vertical limiting plate 13, and the edge of the back plate 2 is clamped in the clamping part 101, so that the frame 1 does not need to reserve additional space for installing screws, making the structure between the frame 1, the back plate 2 and the lamp panel assembly 4 more compact. In this way, not only the overall strength of the panel lamp is improved, but also the effective light emitting area is increased, thereby improving the optical performance.

[0039] Specifically, when the panel lamp is installed, the light bar 3 is installed on the inner side of the frame 1 along the vertical limiting plate 13, and the lamp panel assembly 4 is installed on the support part 102 of the frame 1, so that the lamp panel assembly 4 and the light bar 3 are correspondingly arranged, so that the light emitted by the light bar 3 can be uniformly distributed through the light guide plate, diffusion plate and the like of the lamp panel assembly 4, reducing light damage; after the installation of the light bar 3 and the lamp panel assembly 4 is completed, the edge of the back plate 2 is clamped in the clamping part 101 of the frame 1, at this time the upper and lower end faces of the lamp panel assembly 4 abut against the back plate 2 and the horizontal support bottom plate 11 respectively, and the installation of the panel lamp is completed.

[0040] In summary, the clamping structure is used instead of the screw fixing, combined with the narrow frame design and the bidirectional limiting mechanism, the appearance is improved and the assembly process is simplified, and the light efficiency and structural stability are significantly optimized, the key pain points of the traditional side light panel lamp are comprehensively solved, and the panel lamp has significant practical value and market competitiveness.

[0041] Further, the back plate 2 includes a horizontal top plate 21 and a V-shaped bent edge 22, the V-shaped bent edge 22 is arranged along the edge of the horizontal top plate 21, one end of the V-shaped bent edge 22 is connected with the horizontal top plate 21, and the V-shaped opening of the V-shaped bent edge 22 is arranged upward;

[0042] The clamping part 101 further includes a limiting rib 121, the limiting rib 121 is horizontally arranged on the vertical side plate 12, and the limiting rib 121 is arranged along the length direction of the vertical side plate 12;

[0043] When the V-shaped bent edge 22 is installed on the clamping portion 101, the other end of the V-shaped bent edge 22 is limitedly matched with the limiting rib 121.

[0044] By designing the V-shaped bent edge 22 on the back plate 2 and setting the V-shaped opening upward, this structure not only increases the strength of the back plate 2, but also enhances the connection stability between the back plate 2 and the clamping portion 101 through the V-shaped bending. The V-shaped bent edge 22 is more closely matched with the clamping portion 101, and is not easy to loosen or fall off due to external force. During the installation of the back plate 2, the V-shaped bent edge 22 enables the back plate 2 to be more easily aligned and inserted with the clamping portion 101 during installation. During the installation of the back plate 2 downward, the two wings of the V-shaped bent edge 22 are compressed to be relatively close by the clamping portion 101, and when the back plate 2 is installed in place, the other end of the V-shaped bent edge 22 is clamped by the limiting rib 121, so that the V-shaped bent edge 22 is stably installed inside the clamping portion 101.

[0045] Further, the limiting rib 121 is horizontally arranged on the vertical side plate 12 and extends along the length direction thereof. This design enables the back plate 2 to be limited in all directions by the limiting rib 121 during installation. The other end of the V-shaped bent edge 22 is limitedly matched with the limiting rib 121, which further enhances the stability of the back plate 2 and prevents it from being displaced or deformed during use.

[0046] Further, the bending angle of the V-shaped bent edge 22 is 30°-45°.

[0047] The width D1 of the clamping portion 101 is 3mm-5mm.

[0048] The bending angle of the V-shaped bent edge 22 is set to 30°-45°, and this range of angle design is helpful to enhance the stability of the structure. The bending edge can better resist external force within this angle range, preventing the panel light from being deformed or damaged due to stress during installation or use. At the same time, appropriate bending angle is also conducive to the close matching between the back plate 2 and the frame 1, reducing the shaking and displacement during installation, and improving the accuracy and stability of installation.

[0049] The width D1 of the clamping portion 101 is set to 3mm-5mm, which can not only ensure that the clamping portion 101 has enough strength to bear the weight of the panel light and the stress during installation, but also ensure that the clamping portion 101 is closely and stably matched with the back plate 2 (V-shaped bent edge 22); in addition, it can meet the requirements of narrow frame of the panel light.

[0050] Further, the compressed cotton 5 is arranged between the lamp plate assembly 4 and the back plate 2.

[0051] The compressed cotton 5 is a soft material with good cushioning performance. By arranging the compressed cotton between the lamp panel assembly 4 and the back plate 2, the stress generated by vibration or impact can be absorbed and dispersed, thereby protecting the lamp panel assembly 4 from damage and improving the overall structural stability of the panel lamp.

[0052] In addition, during the assembly of the panel lamp, after the back plate 2 is clamped and installed on the frame 1, the back plate 2 abuts against the top surface of the lamp panel assembly 4. By arranging the compressed cotton 5 with elasticity on the top surface of the lamp panel assembly 4, after the back plate 2 is installed, the compressed cotton 5 rebounds upward and presses the back plate 2, so that the V-shaped bent edge 22 of the back plate 2 is more tightly matched with the limiting rib 121 in the clamping portion 101, thereby avoiding the problem of loose parts during the installation or use of the panel lamp.

[0053] Further, the height H1 of the vertical side plate 12 is not less than the height H2 of the vertical limiting plate 13.

[0054] When the height H1 of the vertical side plate 12 is higher than the height H2 of the vertical limiting plate 13, the overall structure of the panel lamp is better supported in the vertical direction. This design can enhance the anti-overturning ability of the panel lamp during installation and use, preventing it from tilting or deforming due to external forces. In addition, the vertical side plate 12 on the outer side is higher than the vertical limiting plate 13, making the panel lamp look more concise from the side, without the appearance of paragraphs, and the different colors caused by the two materials of the back plate 2 installed on the inner side, making the whole more beautiful.

[0055] Further, the vertical side plate 12 is also provided with a reinforcing rib 122, which is arranged along the length direction of the vertical side plate 12, and the reinforcing rib 122 is located above the limiting rib 121.

[0056] The reinforcing rib 122 is used to enhance the strength of the vertical side plate 12 itself, which helps to reduce looseness and displacement caused by vibration or impact during long-term use, ensuring stable operation of the panel lamp. On the other hand, it increases the heat dissipation area of the vertical side plate 12 to some extent, so that the heat generated during the operation of the panel lamp can be more effectively dissipated through the reinforcing rib 122, reducing the working temperature of the panel lamp and prolonging the service life of the LED light source.

[0057] Further, the lamp panel assembly 4 comprises a diffusion plate 41, a light guide plate 42 and a reflective paper 43 arranged in sequence from bottom to top, and the height of the light guide plate 42 is flush with the height of the lamp strip 3.

[0058] Alternatively, the lamp panel assembly 4 comprises a prismatic plate, an anti-glare film, a light guide plate 42 and a reflective paper 43 arranged in sequence from bottom to top, and the height of the light guide plate 42 is flush with the height of the lamp strip 3.

[0059] The light guide plate 42 can uniformly guide the light emitted by the LED light bar 3 to the entire panel area. Its working principle is to use optical-grade acrylic or PC plate material, through the design of light guide points, to make the light reflect and scatter multiple times inside the plate, thereby achieving the effect of uniform lighting. The diffusion plate 41 is located above the light guide plate 42, and its main function is to further scatter the light emitted by the light guide plate 42, so that the light is more soft and evenly distributed on the panel. This helps to reduce glare and light spots, and improve visual comfort. The reflective paper 43 is located below the light guide plate 42, which reflects the light leaking from the bottom of the light guide plate back into the light guide plate, thereby improving the utilization efficiency of light. This design helps to further enhance the brightness and uniformity of the panel light. The lamp plate assembly 4 makes installation and maintenance more convenient. When it is necessary to replace or clean the optical components, it can be easily disassembled and reinstalled, reducing maintenance costs.

[0060] Further, the diffusion plate 41 can be replaced by a prismatic plate and an anti-glare film. The prismatic plate can more effectively control the diffusion angle of light by its special microstructure, such as a four-sided inverted pyramid surface texture, to suppress high-angle light in non-illumination areas, thereby reducing glare values; the anti-glare film uses optical interference principles to reduce reflection and glare, further improving the imaging quality or lighting comfort of the lighting product. The design of the prismatic plate can enhance the effective light in the center of the illumination area, improve the lighting efficiency, and the combination of the prismatic plate and the anti-glare film usually has a high light transmittance, ensuring that light can be efficiently transmitted, reducing light loss.

[0061] By ensuring that the light guide plate 42 is flush with the height of the light bar 3, a standardized interface between the optical components and the light bar can be achieved. This helps to simplify the production process, improve production efficiency, and reduce production costs.

[0062] Further, the top surface of the end of the support part 102 away from the vertical limiting plate 13 is provided with a support protrusion 111, which abuts against the bottom surface of the lamp plate assembly 4, and the support protrusion 111 is used to hold up the lamp plate assembly 4.

[0063] The support protrusion 111 is mainly used to raise the lamp plate assembly 4, so that the lamp plate assembly 4 can be made of a lighter and thinner material, and to ensure that the center of the light guide plate 42 is aligned with the lamp beads of the light bar 3. In addition, the support protrusion 111 is in contact with the bottom surface of the lamp plate assembly 4, forming a certain gap. This gap design helps to increase the heat dissipation area of the optical components and improve the heat transfer efficiency.

[0064] Further, the width D2 of the support part 102 is 6mm-20mm.

[0065] The width D2 of the support part 102 is in the range of 6mm-20mm, which provides sufficient support area for the lamp panel assembly 4. This enhances the structural strength of the support part 102, so that the lamp panel assembly 4 can be kept stable during installation and use, and is not prone to displacement or deformation.

[0066] Further explanation, the wider the width D2 of the support part 102, the more stable it is to support the lamp panel assembly 4, but this will make the overall size of the panel lamp increase, or the width of the frame becomes larger, therefore, under the premise of meeting the stable support of the lamp panel assembly 4, the width of the support part 102 is not less than 6mm can guarantee that the panel lamp will not appear bright edge, so that the quality and effect of the panel lamp product are better.

[0067] Further, the edge of the back plate 2 is provided with a notch 23, and the notch 23 is used for the conductive element 6 to pass through.

[0068] By setting the notch 23 on the edge of the back plate 2, the conductive element 6 (such as wire) can conveniently pass through the notch and be connected with other parts of the panel lamp. This design avoids the trouble of disassembling the back plate or complicated operation during installation, thereby simplifying the installation steps and improving the assembly efficiency.

[0069] The design of the notch 23 makes the installation position of the conductive element 6 more explicit and intuitive, reduces the difficulty and error rate in the installation process. At the same time, it also helps to ensure the correct connection of the conductive element with other parts of the panel lamp, improves the accuracy and reliability of the installation.
