Description

Technical Field

[0001] This utility model specifically relates to a flat panel lamp. Background Technology

[0002] Existing flat panel lights typically include a base shell, a front shell, a light source, a reflective film, a light guide plate, and a diffuser plate. The base shell and front shell are joined together, with the light source, reflective film, light guide plate, and diffuser plate all positioned between them. The reflective film is attached to one side of the light guide plate, and the other side of the light guide plate faces the diffuser plate. The light source is located on the side of the light guide plate. Currently, the base shell and front shell are fixed together around the perimeter of the base shell using numerous screws. When the front shell is disassembled, the diffuser plate and light guide plate will separate due to the loss of the front shell's grip, posing a risk of separation and damage during disassembly and maintenance at heights.

[0003] Therefore, it is necessary to provide a flat panel lamp structure to improve upon the problems mentioned above. Utility Model Content

[0004] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a flat panel lamp.

[0005] A flat panel light includes an outer frame and an inner frame. The outer frame has a lamp cavity with a lower opening. The inner frame is detachably installed inside the lamp cavity and has mounting cavities with upper and lower openings. The mounting cavity has a recessed cavity along its circumferential sidewall for positioning and placing an LED lamp board. A diffuser plate and a light-transmitting plate are arranged sequentially from top to bottom inside the mounting cavity. A limiting flange is provided along the circumferential top wall of the lamp cavity. A limiting area is formed between the recessed cavity and the limiting flange to limit the movement of the LED lamp board.

[0006] In one embodiment, the inner frame has a recessed groove on its outer side, and the outer frame sidewall has a threaded hole corresponding to the groove, with a limiting member that can fit into the groove being inserted into the threaded hole.

[0007] In one embodiment, the outer frame is formed by splicing four first profiles of the same structural size end to end, and a first angle iron is connected between adjacent first profiles by screws. A cover plate is connected between the four first profiles by screws. The lamp cavity is formed between the four first profiles and the cover plate. The limiting flange is integrally formed with the first profile.

[0008] In one embodiment, the inner frame comprises four second profiles of the same structural size joined end to end, and second angle irons are connected between adjacent second profiles by screws.

[0009] In one embodiment, the inner side of the second profile has a first rib extending laterally, and a second rib extending vertically is provided on the first rib. The cavity is formed between the inner side of the second profile and the second rib. The diffuser plate is disposed on the first rib and abuts against the side wall of the second rib.

[0010] In one embodiment, an EVA buffer plate abuts against the top wall of the lamp cavity.

[0011] In one embodiment, a plurality of heat dissipation fins are provided at vertical intervals on the outer side of the second profile.

[0012] In one embodiment, the inner side of the second profile is recessed below the first rib, and the light-transmitting plate is installed in the mounting groove.

[0013] In summary, the advantages of this utility model over the prior art are:

[0014] This utility model uses an installation method in which the inner frame is inlaid with the outer frame lamp cavity, and the LED lamp board, diffuser plate and light-transmitting plate are installed inside the inner frame. When the inner frame and the outer frame are separated and disassembled, the LED lamp board, diffuser plate and light-transmitting plate are still installed inside the inner frame, thereby effectively avoiding the problem of the LED lamp board, diffuser plate and light-transmitting plate separating, falling and being damaged.

[0015] Furthermore, after the inner frame and outer frame are separated and disassembled, the LED light board can be directly pulled out and disassembled from the recess in the inner frame mounting cavity, which facilitates the subsequent disassembly and maintenance of the LED light board.

[0020] Figure 5 As one embodiment of this utility model Figure 1 Enlarged diagram of point B. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 5 The present invention preferably provides a flat panel lamp, including an outer frame 1 and an inner frame 2. The outer frame 1 has a lamp cavity 3 with a lower opening. The inner frame 2 is detachably installed in the lamp cavity 3 and has mounting cavities 4 with upper and lower openings. The mounting cavity 4 has a recessed cavity 5 along its circumferential sidewall for positioning and placing an LED lamp panel 6. A diffuser plate 7 and a light-transmitting plate 8 are arranged sequentially from top to bottom in the mounting cavity 4. The lamp cavity 3 has a limiting flange 9 along its circumferential top wall. A limiting area is formed between the recessed cavity 5 and the limiting flange 9 to limit the movement of the LED lamp panel 6.

[0023] Specifically, the installation method involves embedding the outer frame lamp cavity into the inner frame, while the LED light panel, diffuser plate, and light-transmitting plate are installed inside the inner frame. When the inner frame and outer frame are separated and disassembled, the LED light panel, diffuser plate, and light-transmitting plate are still installed inside the inner frame, thus effectively avoiding the problem of the LED light panel, diffuser plate, and light-transmitting plate separating, falling off, and being damaged.

[0024] Furthermore, after the inner frame and outer frame are separated and disassembled, the LED light board can be directly pulled out and disassembled from the recess in the inner frame mounting cavity, which facilitates the subsequent disassembly and maintenance of the LED light board.

[0025] Furthermore, the inner frame 2 has a recessed groove 10 on its outer side, and the outer frame 1 has a threaded hole 11 through the groove 10 on its side wall. A limiting member 12 that can engage with the groove 10 is threaded into the threaded hole 11. Specifically, the inner frame is fitted into the lamp cavity of the outer frame, and the limiting member is then screwed to move axially along the threaded hole of the outer frame, causing one end of the limiting member to engage with the groove on the side wall of the inner frame, thereby achieving the installation and fixation between the inner frame and the outer frame.

[0026] Furthermore, the outer frame 1 is composed of four first profiles 13 of the same structural size, spliced ​​end to end. First angle irons 14 are connected between adjacent first profiles 13 by screws, and cover plates 15 are connected between the four first profiles 13 by screws. The lamp cavity 3 is formed between the four first profiles 13 and the cover plates 15. The limiting flange 9 is integrally formed with the first profiles 13. Specifically, users can cut the length of the first profiles according to actual needs to achieve different outer frame sizes, thereby meeting the production needs of flat panel lights of different specifications.

[0027] Furthermore, the inner frame 2 comprises four second profiles 21 of identical structural size joined end to end, with second angle irons 22 connected between adjacent second profiles 21 by screws. Specifically, users can cut the length of the second profiles according to actual needs to achieve different inner frame sizes, thereby meeting the production needs of flat panel lights of different specifications.

[0028] Furthermore, the inner side of the second profile 21 has a first rib 23 extending laterally, and a second rib 24 extending vertically is provided on the first rib 23. The cavity 5 is formed between the inner side of the second profile 21 and the second rib 24. The diffuser plate 7 is disposed on the first rib 23 and abuts against the side wall of the second rib 24. This allows the LED light panel and the diffuser plate to be positioned and placed within the inner frame.

[0029] Furthermore, an EVA buffer plate 25 is abutted between the diffuser plate 7 and the top wall of the lamp cavity 3. This EVA buffer plate effectively prevents the diffuser plate from becoming loose or wobbling.

[0030] Furthermore, the second profile 21 has several heat dissipation fins 26 arranged vertically at intervals on its outer side, which facilitates heat dissipation for the LED light panel.

[0031] Furthermore, the second profile 21 has a recessed mounting groove 27 located below the first rib 23 on its inner side, and the light-transmitting plate 8 is installed in the mounting groove 27. This allows the light-transmitting plate to be fixed within the inner frame.
