Technical Field

[0001] This invention relates to the field of lighting fixtures, and more particularly to continuous light-emitting panel lights and panel light modules. 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 arranged side-by-side to form a panel light module. However, the end plate assemblies of existing panel lights are usually made of opaque, rigid materials. When two adjacent panel lights in a panel light module are lit, observers can see that the ends of the two panels lights that are close to each other are not lit, thus forming a dark area, which greatly affects the lighting effect. Summary of the Invention

The body is connected to the two extension arms respectively. The body and the two extension arms enclose a bottom notch. The end diffuser plate is connected to the end cap. 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 protrudes from the top surface of the main body, and the upper part of the body is provided with a bridging structure.

Continuous illumination panel light. Detailed Implementation

[0018] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 6 Continuous illumination panel lights, including: Body 1, the bottom of body 1 has an opening; A diffusion panel 2 is disposed at the opening; End plate assembly 3 is installed at the end of the main body 1. The end plate assembly 3 includes an end diffuser plate 31 that contacts the diffuser panel 2. The bottom end of the end diffuser plate 31 is located outside the end of the diffuser panel 2. The outer wall surface of the end diffuser plate 31 is at least a portion of the end face of the continuous light-emitting panel lamp.

[0020] As can be seen from the above description, the beneficial effects of the present invention are as follows: The structure of this continuous light-emitting panel lamp is novel, and its end has an end diffuser plate 31, which effectively overcomes the phenomenon that the bottom surface of the end plate assembly 3 in the prior art cannot emit light and forms a dark area, thereby improving the lighting effect to a certain extent. It also enables the junction of two continuously light-emitting panel lamps spliced ​​together in a panel lamp module composed of multiple continuously light-emitting panel lamps to achieve continuous light emission without the phenomenon of brightness reduction, which is beneficial to improving the visual experience of the observer.

[0021] Furthermore, the end plate assembly 3 also includes an end cap 32 that abuts against the end face of the main body 1. The end cap 32 includes a body 321 and two spaced-apart extension arms 322. The body 321 is connected to the two extension arms 322 respectively. 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. At least a portion of the end diffuser plate 31 is located in the bottom window.

[0022] 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 panel lamp under the diffusion effect of the end diffuser 31, which is conducive to further enhancing the visual experience of the observer.

[0023] 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.

[0024] 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 two adjacent continuous light-emitting panel lights 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 of the two spliced ​​continuous light-emitting panel lights.

[0025] Furthermore, the upper part of the body 321 protrudes from the top surface of the main body 1, and the upper part of the body 321 is provided with a bridging structure 324.

[0026] As described above, two adjacent continuous light-emitting panel lights can be fixed to each other through the bridging structure 324, which facilitates the operation of the assembly personnel.

[0027] Furthermore, the end diffuser plate 31 is detachably connected to the end cap 32.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Furthermore, the main body 1 includes a profile, which includes two side plates 12 arranged opposite to each other. The side plates 12 have an upper protrusion 121 and a lower protrusion 122 arranged at intervals. The lower protrusion 122 has a mounting groove 123 arranged along the length direction. The side of the diffuser panel 2 is installed in the mounting groove 123. The inner side of the end cap 32 is provided with an upper limit protrusion 326 and a lower limit protrusion 327. The upper limit protrusion 326 abuts against the bottom surface of the upper protrusion 121, and the lower limit protrusion 327 abuts against the top surface of the lower limit protrusion.

[0032] As can be seen from the above description, the cooperation between the upper limit protrusion 326 and the upper protrusion 121, and the cooperation between the lower limit protrusion 327 and the lower protrusion 122, enables the end cap 32 and the main body 1 to achieve precise positioning, which is beneficial to improving the installation accuracy of the end plate assembly 3 and the main body 1.

[0033] Furthermore, the bottom surface of the end diffuser plate 31 is coplanar with the bottom surface of the diffuser panel 2.

[0034] As can be seen from the above description, the fact that the bottom surface of the end diffuser plate 31 is coplanar with the bottom surface of the diffuser panel 2 is conducive to ensuring the visual effect of the light-emitting surface of the continuous light-emitting panel lamp to a greater extent.

[0035] Furthermore, the inner side of the bottom of the end diffuser plate 31 is provided with an abutting step 312, and the end diffuser plate 31 is attached to the end of the diffuser panel 2 through the abutting step 312.

[0036] As described above, the bottom of the end diffuser plate 31 overlaps with the diffuser panel 2, which ensures that there is no vertical gap between the end diffuser plate 31 and the diffuser panel 2 that directly connects to the internal space of the main body 1. This helps to improve the sealing of the continuous light-emitting panel lamp and ensures that the light inside the main body 1 will not shine out directly through the gap between the end diffuser plate 31 and the diffuser panel 2, thus creating a strong light irradiation area and improving the visual experience of the observer.

[0037] To solve the above-mentioned technical problems, the present invention also adopts the following technical solution: a panel light module, including the above-mentioned continuous light-emitting panel light, wherein the panel light module is composed of multiple of the above-mentioned continuous light-emitting panel lights spliced ​​together.

[0038] As can be seen from the above description, the panel light module can achieve continuous light emission, with good lighting effect and excellent decorative effect.

[0039] Embodiment 1 of the present invention is as follows: Please refer to Figures 1 to 5 A continuous-emission panel light includes a main body 1, a diffuser panel 2, and an end plate assembly 3. The main body 1 contains an LED light strip 4 serving as the light source. The LED light strip 4 has excellent energy-saving performance, resulting in lower power consumption during use. The bottom of the main body 1 has an opening, and the diffuser panel 2 is located at the opening. Most of the light emitted by the LED light strip 4 diffuses outward through the diffuser panel 2. The end plate assembly 3 is installed at the end of the main body 1 and includes an end diffuser plate 31 that contacts the diffuser panel 2. The bottom end of the end diffuser plate 31 is located outside the end of the diffuser panel 2, and the outer wall surface of the end diffuser plate 31 forms at least a portion of the end face of the continuous-emission panel light. A small portion of the light emitted by the LED light strip 4 diffuses outward through the end diffuser plate 31. The diffuser panel 2 can be a conventional diffuser plate, diffuser film, etc.

[0040] The continuous light-emitting panel light is provided with the end plate assembly 3 at at least one end. When the continuous light-emitting panel light is provided with the end plate assembly 3 at only one end, the other end of the continuous light-emitting panel light is closed by an opaque material, such as an aluminum plate or a stainless steel plate, so as to prevent light from escaping from the end face of the continuous light-emitting panel light.

[0041] The main body 1 includes a metal back plate 11, and the LED light strip 4 is directly attached to the metal back plate 11. This allows the heat from the LED light strip 4 to dissipate outwards through the metal back plate 11, 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 working stability of the continuous-light panel light during long-term operation. The 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 continuous-light panel light can be equipped with one or more LED light strips 4 according to brightness requirements.

[0042] Specifically, the 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 structures. However, 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, which helps to reduce the manufacturing cost of the continuous light panel lamp.

[0043] The end plate assembly 3 further includes an end cap 32 that abuts against the end face of the main body 1. The end cap 32 is fastened to the profile. The end cap 32 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. 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.

[0044] 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.

[0045] In one or more embodiments, the upper part of the body 321 protrudes from the top surface of the main body 1, and 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 installing bolts, etc.

[0046] 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.

[0047] 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 main body 1, the end diffuser plate 31 is in contact with the diffuser panel 2. Therefore, the end diffuser plate 31 in the continuous light panel lamp cannot move along the axial direction of the protrusion 325. That is, when the end diffuser plate 31 is connected to the main body 1, the position of the end diffuser plate 31 in the continuous light panel lamp 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 main 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 main 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.

[0048] The side plate 12 has an upper protrusion 121 and a lower protrusion 122 spaced apart vertically. The lower protrusion 122 has a mounting groove 123 along its length, and the side of the diffuser panel 2 is mounted in the mounting groove 123. The inner side of the end cover 32 is provided with an upper limit protrusion 326 and a lower limit protrusion 327. The upper limit protrusion 326 abuts against the bottom surface of the upper protrusion 121, and the lower limit protrusion 327 abuts against the top surface of the lower limit protrusion. The contact positioning of the upper limit protrusion 326 and the upper protrusion 121, combined with the contact positioning of the lower limit protrusion 327 and the lower protrusion 122, allows the end cover 32 to be precisely aligned with the main body 1, facilitating the connection and fixation of the end plate assembly 3 and the main body 1, and ensuring the production consistency of the continuous light-emitting panel lamp.

[0049] In a preferred embodiment, the bottom surface of the end diffuser plate 31 is coplanar with the bottom surface of the 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 diffuser panel 2.

[0050] To prevent light leakage, reduce the manufacturing precision requirements of the diffuser panel 2, and reduce the assembly precision requirements of the continuous light-emitting panel lamp, 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 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.

[0051] Optionally, the inner side of the extension arm 322 is also provided with a receiving groove 328 for the end of the diffusion panel 2 to be inserted. The receiving groove 328 corresponds to the abutting step 312, and one vertical wall of the receiving groove 328 is flush with the vertical surface of the abutting step 312.

[0052] 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 continuous light-emitting panel lamp 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.

[0053] like Figure 6 As shown, this embodiment also provides a panel light module, which includes the aforementioned continuously emitting panel light 5, and the panel light module is composed of multiple of the aforementioned continuously emitting panel lights 5 spliced ​​together.

[0054] The two adjacent continuous light panel lamps 5 are bridged and fixed by the bridging structure 324.

[0055] Preferably, the end diffuser plates 31 of two adjacent continuous light-emitting panel lamps 5 are in contact with each other at their closest ends.

[0056] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
