[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] In existing lighting fixture structures, the fixture structure includes a frame, a back panel, and a lamp body. The frame is used to install the back panel and lamp body. A load-bearing structure such as a hanging plate or a hanging chain is installed on the back panel, and the load-bearing structure is further fixed to the ceiling, thereby realizing the installation of the lighting fixture.

[0023] In existing lighting fixture structures, to avoid excessive weight on the load-bearing structure, the weight of the back panel needs to be controlled. Therefore, the back panel is usually made of cold-rolled steel plate with a thickness of 0.5mm, which has relatively weak strength and consequently poor load-bearing capacity. During the load-bearing test, because the load-bearing structure is connected to the back panel, the back panel will deform significantly and fail the load-bearing test.

[0024] Therefore, this embodiment provides a lamp structure that can meet weight requirements while having strong load-bearing capacity.

[0025] Please see Figures 1 to 9 The lamp structure provided in this embodiment includes a frame 1, a support frame 2, a back plate 3, and a load-bearing component. The back plate 3 is mounted on the frame 1, the support frame 2 is installed on the frame 1, and the load-bearing component is installed on the support frame 2, thereby enabling the frame 1 to bear the load. This facilitates the control of the thickness of the back plate 3 to meet the weight requirements. At the same time, due to the high structural strength of the frame 1, the load-bearing capacity can be effectively improved.

[0026] Please see Figure 3 The lamp structure provided in this embodiment also includes a diffuser plate 5, a light guide plate 6 and a sponge 7. The diffuser plate 5, the light guide plate 6 and the sponge 7 are stacked in sequence. The diffuser plate 5 is located inside the frame 1 and is located on the outermost layer.

[0027] The diffuser plate 5 is semi-transparent and is used to disperse concentrated, glaring light into a uniform and soft surface light source. The diffuser plate 5 can be made of PC (polycarbonate), PMMA (acrylic), or specially treated PET material. The light guide plate 6 is transparent and is used to guide light to the entire plate surface through the principle of total internal reflection. The light guide plate 6 can be made of optical grade PMMA (acrylic) or PC material with high light transmittance. The sponge 7 is used to provide cushioning for the light guide plate 6 and the diffuser plate 5 to prevent the diffuser plate 5 and the light guide plate 6 from being squeezed, deformed, or broken due to transportation, installation, or temperature changes.

[0028] Preferably, please refer to Figure 3 and Figure 4 The frame 1 includes an annular plate 11 and an annular platform 12. The outer wall of the annular platform 12 is circumferentially connected to the inner side of the annular plate 11. The edge of the back plate 3 is circumferentially attached to the top of the annular platform 12 and further circumferentially screwed to the top of the annular platform 12. A step 13 is circumferentially provided on the inner side of the annular plate 11, and a diffuser plate 5 is circumferentially attached to the top of the step 13, thereby confining it to the inner side of the frame 1. More preferably, to improve the overall strength of the frame 1, the annular platform 12 and the step 13 are connected by a first plate, and the first plate and the annular plate 11 are connected by a second plate.

[0029] Optionally, the frame 1 is made of aluminum alloy, which has excellent strength, and the frame is a one-piece molded structure with strong structural strength.

[0030] Optionally, a recessed portion is formed in the middle area of ​​the back plate 3, which abuts against the sponge 7 to limit the diffuser plate 5, the light guide plate 6 and the sponge 7, and prevent the diffuser plate 5, the light guide plate 6 and the sponge 7 from shifting. At the same time, the sponge 7 can provide cushioning for the back plate 3 and the light guide plate 6 to prevent the back plate 3 and the light guide plate 6 from being squeezed.

[0031] Furthermore, the top of the annular platform 12 is provided with a mounting groove 121, which is arranged around the annular platform 12. Several nuts are arranged at intervals around the bottom of the mounting groove 121. Several peripheral screws 10 are used to pass through the back plate 3 in sequence and are screwed to the nuts accordingly, thereby realizing the connection between the back plate 3 and the annular platform 12.

[0032] In this embodiment, a light strip 8 is arranged circumferentially on the inner side of the annular plate 11. The light strip 8 is located between the annular platform 12 and the step 13. Preferably, the light strip 8 is pasted on the annular plate 11 and faces the light guide plate 6.

[0033] Furthermore, the support frame 2 is fitted to the inner wall of the annular platform 12, and the support frame 2 is screwed to the annular platform 12 along the thickness direction of the annular platform 12. The load-bearing component is screwed to the support frame 2. Furthermore, the load-bearing component is installed on the ceiling, thereby enabling the frame 1 to bear the load and improve the load-bearing capacity. Preferably, the load-bearing component is screwed to the top of the support frame 2.

[0034] For example, support frames 2 are provided on both sides of the annular platform 12 to ensure that the weight of the frame 1 is uniform.

[0035] Optionally, the support frame 2 is made of die-cast aluminum alloy, which has excellent strength.

[0036] In some feasible embodiments, the support frame 2 has at least two mounting holes spaced apart along its length. Correspondingly, the annular platform 12 has threaded holes extending through its thickness, with each threaded hole corresponding to a mounting hole. A plurality of fixing bolts 20 are sequentially screwed into the mounting holes and the corresponding threaded holes, thereby fixing the support frame 2 to the annular platform 12. Preferably, the threaded holes in the annular platform 12 communicate with the mounting groove 121.

[0037] In this embodiment, the support frame 2 is provided with three mounting holes spaced apart along its length to ensure that the support frame 2 is firmly fixed to the annular platform 12. For example, a weight-reducing cavity is formed in the middle area of ​​the side of the support frame 2 away from the annular platform 12 to achieve the effect of weight reduction of the support frame 2. A mounting hole is provided at the bottom of the mounting cavity, and a mounting hole is provided at each end of the length direction of the support frame 2.

[0038] Please see Figure 3 and Figure 5 In this embodiment, a hanging platform 21 is also provided on one side of the support frame 2 along its length direction. After the support frame 2 is screwed to the annular platform 12 along the thickness direction of the annular platform 12, the top of the hanging platform 21 can fit against the bottom of the annular platform 12. On the one hand, this is to position the support frame 2, and on the other hand, it expands the contact area between the support frame 2 and the frame 1, improves the connection strength between the support frame 2 and the annular platform 12, and also expands the load-bearing range of the frame 1 and improves the load-bearing capacity of the frame 1.

[0039] Please see Figure 5 and Figure 6 The load-bearing component provided in this embodiment includes a mounting plate 41. For example, the mounting plate 41 is an integrally formed structure, including a connecting lifting plate 411 and a limiting plate 412. The lifting plate 411 and the limiting plate 412 are in an L-shaped structure. Further, the lifting plate 411 is screwed to the support frame 2 using locking bolts 30. At the same time, the limiting plate 412 is inserted into the mounting groove 121, and a limiting groove 4121 is opened on the side of the limiting plate 412 away from the lifting plate 411. One fixing bolt 20 is clamped in the limiting groove 4121, thereby limiting the left and right swaying of the mounting plate 41 and improving the stability of the overall structure.

[0040] In some feasible embodiments, at least two locking bolts 30 are used to fasten the hoisting plate 411 and the support frame 2 to improve the connection strength between the mounting plate 41 and the support frame 2. In this embodiment, two locking bolts 30 are used.

[0041] Further, please refer to Figure 7 A number of clearance holes 31 are made on the back plate 3, and the clearance holes 31 correspond one-to-one with the mounting plate 41. At least part of the clearance holes 31 are exposed on the lifting plate 411 so that the locking bolts 30 can pass through the clearance holes 31 to screw the support frame 2, thereby avoiding the back plate 3 from bearing the weight.

[0042] Please see Figure 2 , Figure 8 and Figure 9 In this embodiment, the load-bearing component also includes a hanging chain 42. Accordingly, a lifting lug is fixed on the top of the support frame 2, one end of the hanging chain 42 is fixed to the lifting lug, and the other end of the hanging chain 42 extends out of the back plate 3 so as to install it on the ceiling.

[0043] Optionally, at least two support frames 2 are spaced apart on each opposite side of the annular platform 12. Each support frame 2 can have a mounting plate 41 or a hanging chain 42 installed on its top, allowing the required number of mounting plates 41 and hanging chains 42 to be set according to actual needs. (See also...) Figure 9 In this embodiment, three support frames 2 are provided at intervals on both sides of the annular platform 12. The two support frames 2 at the edge are equipped with mounting plates 41, and the support frame 2 in the middle is equipped with a hanging chain 42.

[0044] During installation, the lamp structure provided in this embodiment first attaches the light strip 8 circumferentially to the inner side of the annular plate 11, then circumferentially places the diffuser plate 5 on top of the step 13, and then stacks the light guide plate 6 and sponge 7 in sequence. Several fixing bolts 20 are used to screw the support frame 2 to the annular platform 12. Further, the edge of the back plate 3 is circumferentially placed on top of the annular platform 12, and several peripheral screws 10 are used to sequentially pass through the back plate 3 and correspondingly screw into several nuts in the mounting groove 121 to connect the back plate 3 and the annular platform 12. The limiting plate 412 is inserted into the mounting groove 121, and the lifting plate 411 is screwed to the support frame 2 using locking bolts 30.

[0045] The lighting structure provided in this embodiment allows the frame 1 to bear the weight by installing the load-bearing components on the support frame 2. This facilitates the control of the thickness of the back panel 3 to meet weight requirements. At the same time, the frame 1 has high strength, which improves the load-bearing capacity.
