Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures technology, and in particular to a continuous light-emitting splicing panel light module. Background Technology

[0002] The panel light uses ultra-high brightness LEDs as the light source and is suitable for indoor lighting in hotels, bars, restaurants, cafes, subway stations, and home interior decoration.

[0003] To enhance the lighting effect of panel lights, the industry typically uses multiple panel lights spliced ​​together to form panel light modules. Due to factors such as design and adaptability to the installation environment, professionals sometimes design panel light modules with irregular shapes. These irregular shapes sometimes have acute, right, or obtuse angle areas. Because of the presence of the opaque end plates at the ends of the panel lights, when two adjacent panel lights are spliced ​​together to form an acute / right / obtuse angle area, no light is produced at the point where they are close to each other after the two panel lights are lit, thus forming a dark area, which greatly affects the lighting effect. Moreover, even if adjacent panel lights are arranged in a straight line, because the end plates of the panel lights are opaque, a dark area will still be formed at the point where two adjacent panel lights are close to each other, which also affects the lighting effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a continuous light-emitting splicing panel light module with good lighting effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a continuous light-emitting splicing panel light module, including an end plate assembly and several sets of splicing units. Each set of splicing units includes two first panel light units. The first panel light unit includes a first body. The bottom of the first body has a first opening. A first diffusion panel is provided at the first opening. One end of the first body has a splicing bevel. The first diffusion panel forms an inclined end face at the splicing bevel. The inclined end faces of the two first diffusion panels in the splicing unit are in face contact. The other end of the first panel light unit is provided with the end plate assembly. The end plate assembly includes an end diffusion plate. The bottom end of the end diffusion plate is located outside the end of the first diffusion panel.

[0006] Furthermore, the end plate assembly also includes an end cap, which includes a body and two spaced-apart extension arms. The body is connected to the two extension arms respectively, and the body and the two extension arms enclose a bottom notch. The end diffuser plate is connected to the end cap, and at least a portion of the end diffuser plate is located in the bottom window.

[0007] Furthermore, the outer wall surface of the end cap is coplanar with the outer wall surface of the end diffuser plate; or, the outer wall surface of the end diffuser plate protrudes relative to the outer wall surface of the end cap.

[0008] Furthermore, the upper part of the body is provided with a bridging structure.

[0029] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please refer to Figures 1 to 6 A continuous light-emitting splicing panel light module includes an end plate assembly 3 and several splicing units. Each splicing unit includes two first panel light units 10. The first panel light unit 10 includes a first body 1. The bottom of the first body 1 has a first opening. A first diffuser panel 2 is provided at the first opening. One end of the first body 1 has a splicing bevel. The first diffuser panel 2 forms an inclined end face 21 at the splicing bevel. The inclined end faces 21 of the two first diffuser panels 2 in the splicing unit are in contact. The other end of the first panel light unit 10 is provided with the end plate assembly 3. The end plate assembly 3 includes an end diffuser plate 31. The bottom end of the end diffuser plate 31 is located outside the end of the first diffuser panel 2.

[0031] As can be seen from the above description, the beneficial effects of this utility model are as follows: In the continuous light-emitting splicing panel light module, the two first panel light units 10 spliced ​​at an angle are in contact with the inclined end faces 21 of the two first diffuser panels 2 at the splicing point, eliminating the dark area at the splicing point and improving the light-emitting illumination effect at the angle splicing point; moreover, an end plate assembly 3 with an end diffuser plate 31 is provided at the other end of the first panel light unit 10, so that when the second panel light unit 20 needs to be spliced, no dark area is generated between the first panel light unit 10 and the second panel light unit 20, further improving the light-emitting illumination effect at the angle splicing point and enhancing the visual experience of the observer.

[0032] Furthermore, the end plate assembly 3 also includes an end cap 32, which includes a body 321 and two spaced-apart extension arms 322. The body 321 is connected to the two extension arms 322 respectively, and the body 321 and the two extension arms 322 enclose a bottom notch 323. The end diffuser plate 31 is connected to the end cap 32, and at least a portion of the end diffuser plate 31 is located in the bottom window.

[0033] As described above, the end cap 32 with the bottom notch 323 can block light and prevent light from being emitted towards the front, rear and top of the continuous light-emitting splicing panel light module under the diffusion effect of the end diffuser plate 31, which is conducive to further enhancing the visual experience of the observer.

[0034] Furthermore, the outer wall surface of the end cap 32 is coplanar with the outer wall surface of the end diffuser plate 31; or, the outer wall surface of the end diffuser plate 31 protrudes relative to the outer wall surface of the end cap 32.

[0035] As can be seen from the above description, the outer wall surface of the end diffuser plate 31 does not protrude from the outer wall surface of the end cover 32, which can ensure that when the first panel light unit 10 and the second panel light unit 20 are spliced, the two end diffuser plates 31 that are close to each other can achieve surface contact, thereby ensuring that there is no dark area at the boundary between the spliced ​​first panel light unit 10 and the second panel light unit 20.

[0036] Furthermore, the upper part of the body 321 is provided with a bridging structure 324.

[0037] As can be seen from the above description, two adjacent end plate assemblies 3 can be fixed to each other through the bridging structure 324, which facilitates the operation of the assembly personnel.

[0038] Furthermore, the end diffuser plate 31 is detachably connected to the end cap 32.

[0039] As can be seen from the above description, the detachable connection between the end diffuser plate 31 and the end cap 32 facilitates the production and manufacturing of the end plate assembly 3, and also facilitates the subsequent cleaning and replacement of the end diffuser plate 31.

[0040] Furthermore, a portion of the end diffuser plate 31 is located inside the end cap 32, and the end cap 32 has a protrusion 325 on its inner side. The end diffuser plate 31 has a sleeve portion 311 that cooperates with the protrusion 325.

[0041] As can be seen from the above description, the cooperation between the protrusion 325 and the sleeve portion 311 enables the end diffuser plate 31 and the end cap 32 to achieve precise alignment.

[0042] Furthermore, the inner side of the bottom of the end diffuser plate 31 is provided with an abutment step 312.

[0043] As described above, the end diffuser plate 31 can be attached to the first diffuser panel 2 by the abutting step 312, which can ensure that there is no vertical gap between the end diffuser plate 31 and the first diffuser panel 2 that directly connects to the internal space of the first main body 1. This is beneficial to improving the sealing of the first panel lamp unit 10 and ensuring that the light inside the first main body 1 will not shine out directly through the gap between the end diffuser plate 31 and the first diffuser panel 2, thus creating a strong light irradiation area and improving the visual experience of the observer.

[0044] Furthermore, the bottom surface of the end diffuser plate 31 is coplanar with the bottom surface of the first diffuser panel 2.

[0045] As can be seen from the above description, the bottom surface of the end diffuser plate 31 is coplanar with the bottom surface of the first diffuser panel 2, which helps to ensure the visual effect of the light-emitting surface of the first panel lamp unit 10 to a greater extent.

[0046] Furthermore, it also includes a plurality of second panel light units 20, each second panel light unit 20 including a second body 202, at least one end of the second body 202 being provided with the end plate assembly 3, and the end diffuser plate 31 of the second panel light unit 20 near the first panel light unit 10 being in surface contact with the end diffuser plate 31 on the first panel light unit 10.

[0047] As can be seen from the above description, the surface contact between the end diffuser plate 31 of the first panel light unit 10 and the end diffuser plate 31 of the second panel light unit 20 can effectively ensure the lighting effect at the splicing point of the first panel light unit 10 and the second panel light unit 20.

[0048] Furthermore, the two first panel light units 10 in the splicing unit are respectively connected to the second panel light unit 20.

[0049] Please refer to Figures 1 to 6Embodiment 1 of this utility model is: a continuous light-emitting splicing panel light module, including an end plate assembly 3 and several splicing units. Each splicing unit includes two first panel light units 10. The first panel light unit 10 includes a first body 1. The first body 1 is provided with a first LED light strip 4 as a light source. The first LED light strip 4 has good energy-saving performance and can save more electricity during use. The bottom of the first body 1 has a first opening, and a first diffusion panel 2 is provided at the first opening. Most of the light emitted by the first LED light strip 4 is diffused outward through the first diffusion panel 2. One end of the first body 1 is provided with a splicing... The first diffuser panel 2 has an inclined end face 21 at the inclined break point, and the inclined end faces 21 of the two first diffuser panels 2 in the splicing unit are in contact. The other end of the first panel light unit 10 is provided with the end plate assembly 3, which includes an end diffuser plate 31. The bottom end of the end diffuser plate 31 is located outside the end of the first diffuser panel 2. The outer wall surface of the end diffuser plate 31 on the first panel light unit 10 is at least a portion of the end face of the entire first panel light unit 10. A small portion of the light emitted by the first LED light strip 4 diffuses outward through the end diffuser plate 31. The first diffuser panel 2 can be a conventional diffuser plate, diffuser film, etc.

[0050] The first main body 1 includes a metal back plate 11, and the first LED light strip 4 is directly attached to the metal back plate 11. This allows the metal back plate 11 to dissipate heat from the first LED light strip 4 outwards, eliminating the need for a separate heat dissipation structure. This makes the structure more rational, saving the cost of installing a heat sink and ensuring the operational stability of the first panel light unit 10 during long-term operation. The first LED light strip 4 can be fixed to the metal back plate 11 using one or more methods such as adhesive strips, screws, or clips. The first panel light unit 10 can be equipped with one or more first LED light strips 4 according to brightness requirements.

[0051] Specifically, the first main body 1 also includes a profile, which includes two side plates 12 arranged opposite to each other. The metal back plate 11 is fixedly connected to the side plates 12. In one or more embodiments, the metal back plate 11 and the side plates 12 are integrally formed. In this embodiment, the metal back plate 11 and the side plates 12 are separate structures, which are fastened together by screws or other fasteners. The separate arrangement of the metal back plate 11 and the side plates 12 can facilitate the processing and forming of the profile and help reduce the manufacturing cost of the first main body 1.

[0052] The end plate assembly 3 further includes an end cap 32, which includes a body 321 and two spaced-apart extension arms 322. The body 321 is connected to the two extension arms 322 respectively. Preferably, the body 321 and the two extension arms 322 are integrally formed. The body 321 and the two extension arms 322 enclose a bottom notch 323. The end diffuser plate 31 is connected to the end cap 32, and at least a portion of the end diffuser plate 31 is located in the bottom window to close at least the upper portion of the bottom window. Specifically, in the first panel light unit 10, the end cap 32 abuts against the end face of the first body 1, and the end cap 32 is fastened to the profile.

[0053] In this embodiment, the outer wall surface of the end cap 32 is coplanar with the outer wall surface of the end diffuser plate 31; in other embodiments, it is also possible for the outer wall surface of the end diffuser plate 31 to protrude relative to the outer wall surface of the end cap 32. Of course, it is also acceptable for the outer wall surface of the end cap 32 to slightly protrude from the outer wall surface of the end diffuser plate 31 without affecting the visual effect.

[0054] In one or more embodiments, the upper part of the body 321 is provided with a bridging structure 324. Optionally, the bridging structure 324 is a snap-fit ​​structure, a fastening hole for mounting bolts, etc. In the first panel light unit 10, the bridging structure 324 protrudes relative to the top surface of the first body 1.

[0055] In some embodiments, the end diffuser plate 31 and the end cap 32 are integrally formed by insert injection molding; alternatively, the end diffuser plate 31 and the end cap 32 are fixed by heat fusion; or, the end diffuser plate 31 and the end cap 32 are fixed by ultrasonic welding. However, it is preferable that the end diffuser plate 31 and the end cap 32 are detachably connected.

[0056] In this embodiment, a portion of the end diffuser plate 31 is located inside the end cap 32. The end cap 32 has a protrusion 325 on its inner side. The end diffuser plate 31 has a sleeve portion 311 that cooperates with the protrusion 325. That is, when the end diffuser plate 31 and the end cap 32 are assembled, the end diffuser plate 31 can only move along the axial direction of the protrusion 325. When the end plate assembly 3 is connected to the first main body 1, the end diffuser plate 31 is in contact with the first diffuser panel 2. Therefore, the end diffuser plate 31 in the first panel light unit 10 cannot move along the axial direction of the protrusion 325. That is, when the end diffuser plate 31 is connected to the first main body 1, the position of the end diffuser plate 31 in the first panel light unit 10 is fixed. The end diffuser plate 31 and the end cap 32 are not fastened with fasteners, which makes it easier for maintenance personnel to remove the end diffuser plate 31 from the end cap 32. However, in order to facilitate the assembly of the end plate assembly 3 with the first body 1, and to reduce the probability of the end diffuser plate 31 accidentally falling off and being damaged during the removal of the end plate assembly 3 from the first body 1, in one or more embodiments, the protrusion 325 is provided with a threaded hole, the end cap 32 and the end diffuser plate 31 are connected by a fastening screw, the fastening screw engages with the threaded hole, and the head of the fastening screw abuts against the sleeve portion 311, thus fastening the end cap 32 and the end diffuser plate 31, making the end plate assembly 3 a whole, so as to facilitate the assembly and disassembly of the end plate assembly 3.

[0057] In a preferred embodiment, the bottom surface of the end diffuser plate 31 is coplanar with the bottom surface of the first diffuser panel 2. In actual products, it is also acceptable for the bottom surface of the end diffuser plate 31 to be slightly higher or lower than the bottom surface of the first diffuser panel 2.

[0058] To prevent light leakage, reduce the manufacturing precision requirements of the first diffuser panel 2, and reduce the assembly precision requirements of the first panel lamp unit 10, in one or more embodiments, the inner side of the bottom of the end diffuser plate 31 is provided with an abutment step 312, and the end diffuser plate 31 overlaps the end of the first diffuser panel 2 through the abutment step 312. In some embodiments, it is also acceptable for the end diffuser plate 31 not to have the abutment step 312.

[0059] Optionally, the inner side of the extension arm 322 is also provided with a receiving groove 326 for the end of the first diffusion panel 2 to be inserted. The receiving groove 326 corresponds to the abutting step 312, and a vertical wall of the receiving groove 326 is flush with the vertical surface of the abutting step 312.

[0060] In one specific implementation, the end diffuser plate 31 includes a first vertical portion 313, a transition portion 314, and a second vertical portion 315 connected in sequence. The second vertical portion 315 is located in the bottom notch 323, and the first vertical portion 313 is located inside the body 321. The sleeve portion 311 is provided on the first vertical portion 313, and the abutting step 312 is provided at the bottom of the second vertical portion 315. The first vertical portion 313 and the second vertical portion 315 are misaligned in the height direction. This not only saves manufacturing materials for the end diffuser plate 31, thereby reducing the production raw material cost, but also reduces the overall weight of the end plate assembly 3. The transition portion 314 can be either inclined or horizontal, but it is preferred that the transition portion 314 is inclined. The inner side of the bottom end of the main body 321 is provided with a contact slope for contacting the transition portion 314. The transition portion 314 has a mating slope that contacts the contact slope. The mating of the contact slope and the mating slope can improve the sealing performance of the first panel lamp unit 10 to a certain extent. More importantly, the stress concentration phenomenon of the transition portion 314 with the mating slope can be improved, which helps to reduce the risk of accidental breakage of the transition portion 314 and improves the structural stability of the end diffuser plate 31.

[0061] The continuous-emission splicing panel light module also includes several second panel light units 20. Each second panel light unit 20 includes a second body 202, within which a second LED light strip serves as a light source. The bottom of the second body 202 has a second opening, at which a second diffusion panel 201 is located. Most of the light emitted by the second LED light strip diffuses outward through the second diffusion panel 201. At least one end of the second body 202 is provided with the end plate assembly 3. The bottom end of the end diffusion plate 31 in the second panel light unit 20 is located outside the end of the second diffusion panel 201. The outer wall surface of the end diffuser plate 31 on the panel light unit 20 is at least a part of the end face of the second panel light unit 20 as a whole. A small portion of the light emitted by the second LED light strip diffuses outward through the end diffuser plate 31 in the second panel light unit 20. The first panel light unit 10 is connected to the second panel light unit 20. The end diffuser plate 31 of the second panel light unit 20 near the first panel light unit 10 is in surface contact with the end diffuser plate 31 on the first panel light unit 10. In this way, there is no dark area at the splicing point of the first panel light unit 10 and the second panel light unit 20 that affects the lighting effect and visual effect.

[0062] The end diffuser plate 31 in the second panel light unit 20 is attached to the end of the second diffuser panel 201 by the abutment step 312.

[0063] Optionally, the two first panel light units 10 in the splicing unit are respectively connected to the second panel light unit 20.

[0064] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
