Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a frame and a lamp having the same. Background Art

[0002] In the prior art, frames are typically formed by bending a single profile multiple times and welding or gluing the ends together. The profile forms rounded corners at the bends. Because the profile is directly bent using a bending machine, the radius of the rounded corners is relatively large, typically exceeding 30 mm. This large rounded corner of the frame does not look aesthetically pleasing.

[0003] Furthermore, this traditional method often faces difficulties in controlling splicing precision when manufacturing components with rounded edges. In particular, without effective restraints, the edges can easily become skewed during splicing due to uneven force or improper operation, causing the originally designed rectangular structure to deform into a parallelogram, seriously affecting the product's appearance quality and assembly accuracy.

[0024] Compared with the prior art, the technical solution of the embodiment of the utility model has the following beneficial effects:

[0025] The profile of the present invention has a notch in the support wall, forming a connecting portion and a first joint. After the profile is bent along the notch, the second joint on the side wall is bent.

[0046] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0048] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0049] See also Figures 1 to 13 As shown, an embodiment of the present invention provides a lamp 200. In this embodiment, lamp 200 is a flat panel lamp. Lamp 200 includes a back panel 110, a light source assembly 120, and a frame 100. Back panel 110 is provided with a mounting portion 1101 for mounting lamp 200 on a ceiling or suspended ceiling. Mounting portion 1101 is a bayonet structure that allows it to be suspended from a ceiling or suspended ceiling using a chain.

[0050] See also Figures 1 to 3As shown, in this embodiment, the light source assembly 120 includes a light source board 1201 and an electric driving unit 1202 electrically connected to the light source board 1201. The light source board 1201 and the electric driving unit 1202 are respectively mounted on the back plate 110.

[0051] In other embodiments, the light source board 1201 may also be installed in the frame 100 , and an optical element may be provided to reflect the light emitted by the light source board 1201 and emit it from the light outlet.

[0052] The frame 100 is fixedly connected to the back plate 110. Specifically, screw holes are provided on the ribs 16 of the frame 100, and screw assemblies matching the screw holes are provided on the back plate 110. The frame 100 and the back plate 110 are locked together by the screw assemblies.

[0053] To further enhance the lighting effect, in some embodiments, an optical assembly 130 is further provided between the frame 100 and the back panel 110. The optical assembly 130 includes a diffuser plate 1301 and an anti-glare grille 1302. The anti-glare grille 1302 is supported on the frame 100 and its four edges abut against the square corners 15 on the inner side of the frame 100. The edges of the anti-glare grille 1302 do not need to be rounded, which simplifies the production process and significantly reduces manufacturing costs. At the same time, it reduces material waste and processing time, and improves production efficiency and economic benefits. The diffuser plate 1301 is supported between the anti-glare grille 1302 and the light source panel 1201, evenly dispersing the light emitted by the light source assembly 120, ensuring that the light is softer and more evenly distributed during propagation.

[0054] See also Figure 4 As shown, the frame 100 is formed from a profile 1 cut and spliced ​​to form a closed profile. The profile 1 includes sidewalls 11, support walls 12, a notch 13, and a first and second perpendicular plane. The sidewalls 11 extend along the first plane, and the support walls 12 are disposed on the inner surface of the sidewalls 11 and extend along the second plane. The notch 13 is formed between the sidewalls 11 and the support walls 12. By bending the profile 1 along the notch 13, the rounded corners 14 on the outside of the frame 100 and the squared corners 15 on the inside of the frame 100 are formed.

[0055] To enhance the structural strength of the profile 1, several ribs 16 are provided on the sidewall 11. These ribs 16 and the support wall 12 are located on the same inner surface of the sidewall 11, but are separated from each other on the inner surface. This effectively disperses the points of force applied, allowing the profile 1 to more evenly transmit and resist external pressure or tension, significantly enhancing the rigidity and stability of the overall structure. Furthermore, a notch 13 is formed between two adjacent ribs 16.

[0056] Example 1

[0057] After the profile 1 is punched by the punching film, a plurality of cuts 13 are formed on the supporting wall 12 and the second splicing portion 111 .

[0058] See also Figures 4 to 8 As shown, the cutout 13 is defined by a stamping area S. The cross-sectional shape of the stamping area S includes a first sideline S1 overlapping the outer edge of the support wall 12, a second sideline S2 connecting the first sideline S1 and perpendicular to the first sideline S1, a third sideline S3 connecting the second sideline S2 and overlapping the inner edge of the side wall 11, and a fourth sideline S4 connecting the third sideline S3 and the first sideline S1. The fourth sideline S4 is a quarter-circular arc of the same length as the third sideline S3, and the radius of the arc is equal to the radius of the fillet structure 14. This configuration provides a simple shape for the cutout 13, facilitating rapid and accurate blanking operations by the stamping machine.

[0059] In order to facilitate the punching die to punch out the notch 13 on the profile 1 and avoid the side wall 11 or sharp corners, a punching groove 19 with a width of 1mm to 2mm is respectively opened between a part of the side wall 11 and two adjacent support walls 12, and between a part of the side wall 11 and two adjacent ribs 16. The punching groove 19 constitutes a part of the notch 13. The punching groove 19 extends along the length direction of the third side line S3 and partially coincides with the fourth side line S4.

[0060] See also Figures 4 and 5 As shown, the cutout 13 divides the support wall 12 to form a splicing portion 121. The splicing portion 121 includes a connecting portion 1211 and a first splicing portion 1212 facing the cutout 13 and configured to splice with the side wall 11. The connecting portion 1211 and the first splicing portion 1212 are located on either side of the cutout 13. A stamped groove 19 is provided at the connection between the first splicing portion 1212 and the side wall 11. The cutout 13 forms a second splicing portion 111 on the side wall 11.

[0061] In some embodiments, the sidewall 11 is not provided with the ribs 16. The deformed second splicing portion 111 is spliced ​​with the first splicing portion 1212, and the connecting portion 1211 is spliced ​​with the support wall 12 on one side of the cutout 13 to form the rounded corner structure 14 of the frame 100. The connecting portion 1211 is spliced ​​with the inner sidewall 1213 of the support wall 12 on the side where the first splicing portion 1212 is connected, thereby making the inner sidewalls 1213 of the support wall 12 on both sides of the cutout 13 perpendicular to each other, forming the square corner 15 on the inner side of the frame 100.

[0062] In other embodiments, a plurality of ribs 16 are provided on the side wall 11. The incision 13 divides the rib 16 into two adjacent splicing portions 161. The splicing portion 161 includes a first portion 1611 and a second portion 1612 facing the incision 13 and used for splicing with the side wall 11. A second splicing portion 111 corresponding to the incision 13 is provided on the side wall 11. After the profile 1 is bent along the incision 13, the second splicing portion 111 is bent and spliced ​​with the first splicing portion 1212 and the second portion 1612, respectively, and the connecting portion 1211 and the first portion 1611 are spliced ​​with the support wall 12 or the rib 16 on one side of the incision 13 to form the rounded corner structure 14 on the outside of the frame 100.

[0063] The incision 13 can be welded or glued together. During the welding or gluing process, the splicing portion 121 is prone to unstable shaking and tilting, making it difficult for the spliced ​​shape of the frame 100 to meet the ideal shape standard. For example, the frame 100 is intended to be welded into a rectangle, but it may instead form an irregular shape such as a parallelogram. This shape deviation not only affects the aesthetics of the frame 100, but more importantly, it will adversely affect the subsequent assembly process, reducing the overall product yield and production efficiency. The yield rate of the frame produced in this way is about 80%.

[0064] During the stitching process of the incision 13, the splicing portion 121 is stabilized to facilitate the welding of the profile 1 into a frame 100 of an ideal shape. A plurality of first positioning portions 17 are provided on the first splicing portion 1212, and a second positioning portion 18 corresponding to the first positioning portion 17 is provided on the second splicing portion 111.

[0065] Preferably, the remaining portion of the first splicing portion 1212 after removing the first positioning portion 17 is a quarter arc structure, and the length of the second splicing portion 111 is equal to the circumference of the quarter arc structure. The radius of the quarter arc structure is equal to the width of the support wall 12 .

[0066] In some embodiments, a plurality of first positioning portions 17 are provided on the second portion 1612 , and a second positioning portion 18 corresponding to the first positioning portions 17 is provided on the second splicing portion 111 .

[0067] The first positioning portion 17 and the second positioning portion 18 cooperate to achieve precise alignment and a secure connection between the splicing portions 121, effectively preventing deviation during the splicing process and ensuring the ideal shape and dimensional accuracy of the final frame 100. This arrangement can increase the yield rate of the frame 100 to 98%.

[0068] In this embodiment, two second positioning portions 18 are provided on the second splicing portion 111, and first positioning portions 17 corresponding to the second positioning portions 18 are provided on the first splicing portion 1212 and the second portion 1612, respectively. The second positioning portions 18 are protrusions, specifically ribs, that protrude toward the cutout 13. The first positioning portions 17 are grooves that match the protrusions.

[0069] In other embodiments, the first positioning portion 17 may also be a protrusion protruding toward the incision 13 , and the second positioning portion 18 may be a groove matching the protrusion.

[0070] Preferably, the shape of the protrusion is any one or a combination of semicircular, arched, triangular or truncated cone. The semicircular or arched protrusion can smoothly slide into the corresponding groove during the splicing process, reducing direct friction and interference between the splicing parts 121.

[0071] The triangular or truncated cone-shaped protrusions can provide clear positioning points, so that the splicing portion 121 can be precisely spliced ​​according to design requirements, avoiding misalignment and deviation.

[0072] The cutout 13 is configured such that after the profile 1 is bent along the cutout 13, the portion of the sidewall 11 located outside the cutout 13 is bent, causing the second splicing portion 111 to bend. The second splicing portion 111 then joins with the first splicing portion 1212 and the second portion 1612, respectively. The protrusion and the groove engage, and the profile 1 stops bending. At this point, the second splicing portion 111 joins with the first splicing portion 1212 and the second portion 1612, respectively. The connecting portion 1211 joins with the support wall 12 on one side of the cutout 13, and the first portion 1611 joins with the rib 16 on the other side of the cutout 13, forming the rounded corner structure 14 on the outside of the frame 100.

[0073] The protrusions and grooves engage, providing a position limit during assembly. The inner sidewalls 1213 of the support wall 12, located on either side of the notch 13, are perpendicular to each other, forming a 90-degree angle, thereby achieving preliminary positioning and securing of the joint 121. This allows the joint 121 to maintain its shape when subjected to external forces, facilitating the welding of the frame 100 into a rectangular shape and improving the yield rate.

[0074] In some embodiments, the radius of the rounded corner structure 14 is between 10 mm and 20 mm, avoiding the appearance of bulkiness caused by excessively rounded corners and enhancing the aesthetics of the lamp 200. The maximum protrusion length of the protrusion is 1 mm to 3 mm, which ensures precise positioning between the joints 121 while avoiding the need for an increased welding area due to excessive protrusion. A moderate protrusion not only simplifies the welding process and reduces welding difficulty, but also reduces the amount of welding material used, thereby reducing production costs. Furthermore, a smaller welding area also helps improve welding quality, reducing welding defects and subsequent maintenance costs.

[0075] See also Figures 7 and 8 As shown, after the incision 13 is sewn, a first sewing line L1, a second sewing line L2, a third sewing line L3 and a fourth sewing line L4 are formed. Among them, the first sewing line L1 is located at the junction of two adjacent support walls 12, so that the connection between the support walls 12 is more secure. The second sewing line L2 is located at the junction of two adjacent ribs 16, so that the connection between the ribs 16 is more secure. The third sewing line L3 is located at the junction of a portion of the side wall 11 and two adjacent support walls 12, and the fourth sewing line L4 is located at the junction of a portion of the side wall 11 and two adjacent ribs 16. This arrangement makes the connection between the side wall 11, the ribs 16 and the support part more secure, thereby improving the structural strength and rigidity of the frame 100. After polishing the various sewing lines, the gaps and unevenness originally caused by the incision 13 become almost invisible, and a frame 100 with an integrated appearance and higher structural strength can be obtained.

[0076] Preferably, the protrusion is provided in the middle of L4, which can fix the splicing portion 121 more accurately and stably, and is conducive to the stable welding of the profile 1.

[0077] Example 2

[0078] The above embodiment 1 provides a frame 100 for use in a lamp 200. The principle of the embodiment 2 of the present invention is the same as that of the embodiment 1, except for the structure of the cutout 13. Therefore, only the differences in structure are described here, and the same parts are not repeated.

[0079] See also Figure 9 As shown, the cutout 13 is defined by a stamping area S, and the cross-sectional shape of the stamping area S includes a fifth side line S5, a sixth side line S6, a seventh side line S7, an eighth side line S8, a ninth side line S9, and a tenth side line S10 connected end to end in sequence. The fifth side line S5 overlaps with the outer edge of the support wall 12, and the eighth side line S8 overlaps with the inner edge of the side wall 11. The sixth side line S6, the seventh side line S7, the ninth side line S9, and the tenth side line S10 are of equal length, and the sixth side line S6 is perpendicular to the tenth side line S10. The seventh side line S7 and the ninth side line S9 are both 1 / 8 arcs, and the radius of the arcs is equal to the radius of the rounded structure 14. The length of the eighth side line S8 is twice the length of the seventh side line S7.

[0080] See also Figures 10 and 11As shown, the incision 13 divides the support wall 12 into a splicing portion 121. The splicing portion 121 includes a first splicing portion 1212, a second splicing portion 111, and two connecting portions 1211. After the profile 1 is bent along the incision 13, the connecting portion 1211 connected to the side wall 11 is bent. The deformed side wall 11 and the two connecting portions 1211 are spliced ​​together, and the first splicing portion 1212 and the second splicing portion 111 are spliced ​​together to form the rounded corner structure 14 of the frame 100. The first splicing portion 1212 and the second splicing portion 111 are spliced ​​together, so that the inner side walls 1213 on both sides of the incision 13 on the support wall 12 are perpendicular to each other, forming the square corner portion 15 on the inner side of the frame 100.

[0081] Preferably, a plurality of ribs 16 are provided on the side wall 11. The incision 13 divides the ribs 16 into a splicing portion 161. The splicing portion 161 includes a connecting portion and a first portion 1611 and a second portion 1612 connected to the connecting portion. The first portion 1611 and the second portion 1612 are arranged opposite to each other. After the profile 1 is bent along the incision 13, the side wall 11 is partially bent, and the connecting portion connected to the side wall 11 is bent. The deformed side wall 11 is spliced ​​with the connecting portion and the two connecting portions 1211, the first splicing portion 1212 and the second splicing portion 111, and the first portion 1611 and the second portion 1612 are spliced ​​to form the rounded corner structure 14 on the outside of the frame 100. Similarly, the first portion 1611 and the second portion 1612 are spliced ​​so that the inner walls of the ribs 16 on both sides of the incision 13 are perpendicular to each other, also forming a square corner portion on the inside of the frame 100.

[0082] Furthermore, the first joint portion 1212 is provided with a plurality of first positioning portions 17, and the second joint portion 111 is provided with second positioning portions 18 corresponding to the first positioning portions 17. In this embodiment, the first positioning portions 17 are projections, specifically ribs, protruding toward the cutout 13. The second positioning portions 18 are grooves that match the projections and are oriented away from the cutout 13.

[0083] After being joined, the two connecting portions 1211 form a quarter-circular arc structure. Preferably, both connecting portions 1211 form a quarter-circular arc structure. The radius of the arc is equal to the radius of the fillet structure 14, and the radius of the quarter-circular arc structure is equal to the width of the support wall 12. Furthermore, the length of the portion joining the side wall 11 and the two connecting portions 1211 is equal to the circumference of the quarter-circular arc structure.

[0084] In order to facilitate the punching die to punch out the notch 13 on the profile 1 and avoid the situation of thin-walled sharp corners, preferably, a punching groove 19 is opened at the connection position between the two connecting parts 1211 and the side wall 11, and the punching groove 19 constitutes a part of the notch 13. In this embodiment, the punching groove 19 extends along the length direction of the eighth side line S8, and the two ends of the punching groove 19 partially overlap with the seventh side line S7 and the ninth side line S9 respectively.

[0085] The cutout 13 is configured such that after the profile 1 is bent along the cutout 13, the portion of the sidewall 11 located outside the cutout 13 is bent. The deformed sidewall 11 is spliced ​​with the connecting portion and the two connecting portions 1211, the first splicing portion 1212 and the second splicing portion 111, and the first portion 1611 and the second portion 1612. When the protrusion and the groove engage, the profile 1 stops bending. The splicing of the sidewall 11 and the two connecting portions 1211, the splicing of the first splicing portion 1212 and the second splicing portion 111, the splicing of the sidewall 11 and the connecting portion, and the splicing of the first splicing portion 1212 and the second portion 1612 form the rounded corner structure 14 on the outside of the frame 100.

[0086] See also Figures 12 to 13 As shown, after the incision 13 is stitched, a first stitching line L1, a second stitching line L2, a third stitching line L3, and a fourth stitching line L4 are formed. The first stitching line L1 is located at the junction of two adjacent support walls 12, the second stitching line L2 is located at the junction of two adjacent ribs 16, the third stitching line L3 is located at the junction of a portion of the side wall 11 and two adjacent support walls 12, and the fourth stitching line L4 is located at the junction of a portion of the side wall 11 and two adjacent ribs 16. After polishing each stitching line, a frame 100 with a one-piece appearance and higher structural strength is obtained.

[0087] Example 3

[0088] The above-mentioned embodiment 2 provides a frame 100 for use in a lamp 200. The principle of embodiment 3 of the present invention is the same as that of embodiment 2, except that the positions and numbers of the first positioning portions 17 and the second positioning portions 18 are different. Therefore, only the differences in structure are described here, and the same parts are not repeated.

[0089] A plurality of mutually corresponding first positioning portions 17 and second positioning portions 18 are respectively provided on the two spliced ​​connecting portions 1211. Similarly, a plurality of mutually corresponding first positioning portions 17 and second positioning portions 18 can also be respectively provided on both sides of the corresponding splicing of the connecting portion.

[0090] In some embodiments, there is one first positioning portion 17 and one second positioning portion 18. That is, one corresponding first positioning portion 17 and one corresponding second positioning portion 18 are provided on each of the two joined connecting portions 1211. The first positioning portion 17 is a protrusion, specifically a rib, protruding toward the cutout 13. The second positioning portion 18 is a groove extending away from the cutout 13 and matching the protrusion.

[0091] In summary, the profile 1 of the present invention is provided with a cutout 13 on the support wall 12, and a connecting portion 1211 and a first splicing portion 1212 are formed on the support wall 12. After the profile 1 is bent along the cutout 13, the second splicing portion 111 on the side wall 11 is bent.
