Detailed Implementation

[0028] Please refer to Figures 1 to 2 , Figure 1This is a schematic diagram of the rear view of an embodiment of the panel light 100 of the present invention, showing the state where the locking member 25 and the plug 26 are not installed. Figure 2 This is a front view schematic diagram of an embodiment of the panel light 100 of the present invention. In some embodiments, the panel light 100 is adapted to be mounted on an external support 200 (such as a ceiling, wall, steel frame, etc.). Figure 4 (As shown).

[0029] In some embodiments, the panel light 100 includes a chassis 1, a diffuser plate 14, and a frame 2. The chassis 1 includes a plurality of sidewalls 11. The diffuser plate 14 is disposed on the chassis 1 (e.g., Figure 3 (As shown). The frame 2 is attached to an extended edge around the outer edge of the plurality of sidewalls 11, and the chassis 1 is made of cold-rolled steel sheet. The frame 2 has an elongated groove 20, which is engaged with the extended edge of the outer edge of the plurality of sidewalls 11 by fasteners 29.

[0030] In some embodiments, the frame 2 is an aluminum profile, and the cross-section of the frame 2 is generally L-shaped. The inner side of the frame 2 is integrally formed with an assembly frame structure 21, and the cross-section of the assembly frame structure 21 is generally rectangular.

[0031] In some embodiments, the assembly frame structure 21 is a hollow structure, and the outer surface 21a of the assembly frame structure 21 is located on the visible surface outside the panel light 100, which facilitates the assembly of the locking member 25.

[0032] In some embodiments, the outer surface 21a of the assembly frame structure 21 is provided with a plurality of observable keyholes 211 with a diameter ranging from 5 mm to 15 mm (e.g., Figure 3 (As shown).

[0033] In some embodiments, the inner surface 21b of the assembly frame structure 21 is located inside the panel light 100, and the inner surface 21b of the assembly frame structure 21 is provided with a plurality of concealed key holes 212 with a diameter ranging from 2 mm to 8 mm, and each visible key hole 211 leads to each concealed key hole 212.

[0034] In some embodiments, on the same panel light 100, the visible keyholes 211 on the outer surface 21a of the assembly frame structure 21 are larger than the concealed keyholes 212 on the inner surface 21b of the other side of the assembly frame structure 21.

[0035] In some embodiments, the panel light 100 includes a plurality of light strips 3 (such as...). Figure 9 As shown, the power supply box 4 is located between the chassis 1 and the frame 2. Modules (such as sensing modules and emergency modules) are mounted on the side of the power supply box 4. The light strip 3 includes multiple LED beads 31. The light strip 3 can be two pieces spliced ​​together or a single piece. Each light strip 3 is located in the receiving groove 10 of the chassis 1.

[0036] In some embodiments, the visible keyhole 211 and the concealed keyhole 212 are provided at two positions in the vertical direction along the same axis, providing the user with convenient vertical locking of the locking member 25 into the visible keyhole 211 and the concealed keyhole 212 to the external support member 200.

[0037] In some embodiments, when the panel light 100 is installed, the panel light 100 is flat against the external support 200 (such as the ceiling), and multiple locking pieces 25 (such as screws) are respectively locked into the cavities 21c of the assembly frame structure 21 through the visible lock holes 211 to the concealed lock holes 212 and locked to the external support 200; then, the head end 251 of each locking piece 25 is fixed to each cavity 21c, and multiple plugs 26 are respectively inserted into each cavity 21c through the visible lock holes 211, thus completing the installation. The installation efficiency is quite fast, for example, more than ten times that of the conventional panel light plus ceiling frame installation method.

[0038] In some embodiments, the border 2 is composed of two opposing first sides 2a and two opposing second sides 2b (e.g., Figure 1 As shown, the frame 2 forms a rectangular frame (or a square frame). The two first sides 2a of the frame 2 are two long supports, and the two second sides 2b of the frame 2 are two short supports. The two long supports and the two short supports are connected end to end, but this is not a limitation. In some embodiments, the frame 2 can be a one-piece rectangular frame.

[0039] In some embodiments, each visible keyhole 211 is respectively disposed on each first side 2a (e.g., Figure 1 (as shown), or each visible keyhole 211 is respectively provided on each second side 2b (as shown). Figure 5 As shown, the visible keyhole 211 can have various distribution patterns, and is not limited to this.

[0040] In some embodiments, the frame 2 is provided with a plurality of functional holes 27 (e.g., Figure 5 As shown), each hole 27 can be equipped with a functional module 7, including but not limited to a switch 71, an indicator light 72, and a sensing component 73. Each functional module 7 respectively switches 71, indicator lights 72, and sensing components 73 (e.g., ...). Figure 5 (Right side)

[0041] In some embodiments, in addition to the holes required on the frame 2, multiple additional holes 27 are added to realize emergency, sensing or other functions. These functions can be mounted individually on the lamp or in combination.

[0042] In some embodiments, when a certain function is required, the function module 7 is placed in the groove formed between the frame 2 and the inclined side of the chassis 1, and the driver for the corresponding function module 7 is placed in an adjacent position. In this way, the expanded functions of the panel light can be achieved with the lowest cost and the lowest assembly difficulty without changing the overall appearance of the panel light 100.

[0043] In some embodiments, the border 2 has a perimeter 22 (e.g., Figure 6 As shown), an additional edging is added around the perimeter of the frame 2, with the length of the edging 22 extending beyond the bottom wall 12 of the chassis 1. The frame 2 and the edging 22 are an integral structure, meaning that the edging and the frame 2 are extruded together.

[0044] In some embodiments, the perimeter 22 extends at least 1 mm beyond the bottom wall 12 of the chassis 1, and a wiring space 13 exists between the bottom wall 12 of the chassis 1 and the external support 200; by limiting the height of the perimeter 22, after the panel light 100 is assembled into the ceiling, the perimeter 22 is at least 1 mm higher than the chassis 1, thus providing a wiring space 13 (e.g., ...). Figure 4 (As shown); This setup avoids the need to install a separate cable tray on the ceiling during installation, as the gap between the chassis 1 and the ceiling becomes the cable routing space 13; This design of the cable routing space 13 can save a significant amount of installation time.

[0045] In some embodiments, the width of the cavity 21c of the assembly frame structure 21 ranges from 6 mm to 12 mm, and the height ranges from 3 mm to 15 mm (e.g., Figure 7 (As shown). The cavity 21c and the surrounding edge 22 can work together to significantly increase the structural strength, which is far greater than that of structures with only the surrounding edge 22 or only the cavity 21c.

[0046] In some embodiments, the overall height of the chassis 1 ranges from 17mm to 25mm, and the overall height of the panel light 100 ranges from 22mm to 30mm (e.g., ...). Figure 8 (As shown); Reducing the overall height of the lamp can significantly reduce packaging and shipping costs; Compared to the commonly available 32mm to 40mm panel lights, material costs are reduced by 6.7% to 22%, transportation costs by 12.5% ​​to 37.5%, and packaging costs are also appropriately reduced.

[0047] In some embodiments, a lens 32 with a light emission diffusion angle in the range of 150 degrees to 180 degrees is disposed above the lamp bead 31 (e.g., Figure 9 (As shown); The lens 32 used on the lamp bead 31 can increase the light emission range of a single lamp bead 31, thereby reducing the number of lamp beads 31 on the basis of ultra-thin lamp, while ensuring uniform light emission of the whole lamp.

[0048] In some embodiments, the spacing between each light strip 3 is in the range of 50mm to 100mm (e.g., Figure 10 (As shown); the interval setting of each light strip 3 allows for uniform light emission even with a minimal number of LED beads 31 while maintaining the overall ultra-thin design.

[0049] In some embodiments, the power supply box 4 has an elongated structure, and the power supply box 4 is located between the chassis 1 and the frame 2 and at one corner (e.g., ...). Figure 11 As shown, the power supply box 4 is grounded to the chassis 1. The power supply box 4 is made into a long and narrow shape and placed in the groove formed by the frame 2 and the inclined side of the chassis 1. This avoids the need for additional space on the panel light 100 to house the power supply box 4, making installation more convenient. Furthermore, when the power supply box 4 is fixed using a method such as screw fasteners or adhesive bonding and grounded to the chassis 1, the power supply can be made non-isolated, which saves costs and improves the overall light effect.

[0050] In summary, the panel light according to an embodiment of the present invention achieves a screwless appearance after installation, and the installation is quite convenient and quick. Furthermore, in some embodiments, functional holes are added to the frame, enabling various expansion functions at the lowest cost without affecting the appearance. In addition, in some embodiments, the gap between the chassis and the ceiling serves as wiring space, avoiding the need for a separate wiring channel and saving installation time. Furthermore, in some embodiments, the cavity of the assembly frame structure combined with the surrounding edge increases structural strength. The height of the chassis and the entire light is reduced, effectively saving materials, transportation, and packaging costs.

Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this invention, or equivalent structural or procedural transformations made using the description and drawings of this invention, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this invention.
