Description
Technical Field
[0001] This utility model relates to the field of LED technology, specifically to an LED display light cube. Background Technology
[0002] LED displays consist of a matrix module structure composed of multiple light-emitting diodes evenly arranged. Controlled by a software system, they can display various information such as color and lighting effects in three dimensions. With the development of LED display technology, large-screen advertising screens and decorative displays in shop windows have begun to adopt LED display technology. However, existing LED displays typically achieve a two-dimensional planar display effect.
[0003] During the development of LED display technology, some inventors have improved traditional LED displays. For example, Chinese patent document with authorization announcement number "CN206179327U" shows a light cube, which includes an LED cube lamp body and a PCB circuit board. The front side of the PCB circuit board is provided with multiple rows of pins. The spacing and number of the pins match and are connected to the positive and negative pins of the LED cube lamp body to achieve three-dimensional display, so as to make the display effect more vivid and more spatial.
[0004] The existing technology has the following drawbacks: In the above solution, the spacing and number of the pins are matched and connected to the positive and negative pins of the LED cubic lamp body. Therefore, the LED cubic lamp body must be welded into a cubic structure composed of N×N×N LED bulbs. It is not convenient for modular assembly and it is difficult to flexibly adjust the size and structure according to different usage scenarios, which limits the flexibility and scalability of the application. At the same time, the structure occupies a lot of space and is easily damaged during transportation, increasing transportation costs and risks. Therefore, there is room for improvement.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] Figure 1 A schematic diagram of the overall structure of the LED display light cube provided in this embodiment of the utility model; Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 A front view of an LED display light cube provided in an embodiment of this utility model; Figure 4 for Figure 3 Enlarged view of point B in the middle; Figure 5 for Figure 3 Enlarged view of point C in the middle; Figure 6 A bottom view of the LED display light cube provided in an embodiment of this utility model.
[0023] The LED display light cube provided in this embodiment can be applied to scenarios such as stage performances, exhibitions, advertising and large-scale events. In this embodiment, by improving the structure of the LED display light cube, the size of the light cube can be flexibly adjusted according to different usage scenarios and the light cube can be quickly assembled.
[0024] Please see Figures 1-6 The LED display light cube provided in this embodiment includes a display sub-unit 001, a power line 002, and a signal line 003. The display sub-unit 001 includes a power module 100, a signal module 200, a connection terminal 300, and at least one set of display modules 400. The power module 100 and the signal module 200 are respectively connected to the display modules 400, and adjacent sets of display modules 400 are connected through the connection terminal 300. The power line 002 is used to connect the power module 100 on the adjacent display sub-unit 001, and the signal line 003 is used to connect the signal module 200 on the adjacent display sub-unit 001. Conductive terminals 401 are respectively provided at both ends of the display module 400, with the first end being... The conductive terminals 401 on the display module 400 are connected to the power module 100. The conductive terminals 401 on the non-first end of the display module 400 are connected to the conductive terminals 401 on the adjacent display module 400 through the connection terminals 300 to realize the power connection between the two adjacent sets of display modules 400. Signal terminals 402 are also provided at both ends of the display module 400. The signal terminals 402 on the first end of the display module 400 are connected to the signal module 200. The signal terminals 402 on the non-first end of the display module 400 are connected to the signal terminals 402 on the adjacent display module 400 through the connection terminals 300 to realize the signal connection between the two adjacent sets of display modules 400.
[0025] Specifically, the connecting terminal 300 can be a CNC-machined tin-plated copper terminal. By dividing the LED display light cube into multiple independently set display sub-units 001, power and signal connections between adjacent display sub-units 001 are achieved through power lines 002 and signal lines. At the same time, the display sub-unit 001 also includes multiple display modules 400, and adjacent display modules 400 are connected through the connecting terminal 300. This realizes the expansion of the LED display in different directions, and allows for flexible adjustment of the size and structure of the LED display according to different usage scenarios. This achieves the scalability and flexibility of the LED display. In addition, the modular design facilitates quick assembly and disassembly. It can be disassembled and packaged during transportation, reducing the transportation space occupied during transport, avoiding vibration and damage caused by transporting the whole structure, and improving the safety and controllability of the product during transportation.
[0026] Furthermore, the connecting terminal 300 is provided with a through hole 301 along the first direction, and a notch structure 302 is provided on the outer side of the through hole 301. Two adjacent sets of conductive terminals 401 or two adjacent sets of signal terminals 402 are respectively welded to the two ends of the through hole 301. The notch structure 302 is used to assist in positioning the conductive terminals 401 or signal terminals 402. Specifically, the notch structure 302 is a recessed positioning groove, preferably stepped, which can serve as a concentrated area for molten solder during soldering and also play a role in directional guidance and component positioning during soldering, preventing the conductive terminals 401 or signal terminals 402 from being misaligned or rotated. The position of the notch is opposite to the through hole 301, so that the operator can quickly identify the insertion direction of the conductive terminals 401 or signal terminals 402 during assembly and perform precise soldering operations on the solder joints, thereby effectively improving the reliability and production efficiency of module splicing.
[0027] Furthermore, the connecting terminal 300 has rounded corners around its perimeter, meaning that the edges and corners of the connecting terminal 300 are rounded to form an arc-shaped transition surface. This effectively reduces the sharpness of the edges of the connecting terminal 300, reduces the risk of mechanical damage caused by sharp edges during assembly, and improves operator safety and equipment lifespan.
[0028] Furthermore, the display module 400 also includes multiple sets of substrates 403 and light-emitting units 404. The light-emitting units 404 are disposed on the substrates 403 and electrically connected to the substrates 403. The conductive terminals 401 include first electrode terminals 411 and second electrode terminals 412. Two sets of first electrode terminals 411 are provided, and the two sets of first electrode terminals 411 are connected in parallel with each set of substrates 403 to form a closed loop. Two sets of second electrode terminals 412 are provided, and the second electrode terminals 412 are used to connect to the first electrode terminals 411 on two adjacent sets of display modules 400 via connecting terminals 300. Specifically, the substrate 403 can be made of aluminum substrate, FR-PCB substrate, copper substrate, or other metal composite conductive material, and its surface is etched with PCB pads to form the wiring structure required for power supply and signal connection. The light-emitting units 404 preferably use LED beads, which are fixed to the surface of the conductive substrate 403 or embedded in the structure via pads and electrically connected to the substrate 403 to achieve power-on light emission display. The light-emitting units 404 can be evenly distributed on multiple surfaces or edges of the substrate 403 during layout, thereby enhancing the three-dimensional light-emitting effect and stereoscopic display performance of the light cube.
[0029] The conductive terminal 401 is used to conduct the power supply current output by the power module 100 to the light-emitting unit 404 on the multiple substrates 403. In this embodiment, the conductive terminal 401 is arranged to penetrate the multiple substrates 403 along the first direction, thereby forming a stable longitudinal power supply path. The conductive terminal 401 can be selected from multiple longitudinally arranged solid copper rods, tin-plated brass tubes, or other linear materials with excellent conductivity. Those skilled in the art can select the above structure according to actual needs, so it will not be described in detail in this embodiment.
[0030] For example, the substrate 403 has mounting openings at both ends, which are semi-circular. During installation, the substrate 403 is arranged on a fixture with equally spaced slots, and the first electrode terminals 411 are respectively snapped into the mounting openings and welded in place. In the same set of display modules 400, the second electrode terminal 412 is connected to the first electrode terminal 411. In two adjacent sets of display modules 400, the second electrode terminal 412 is connected to the first electrode terminal 411 on the adjacent display module 400 through the connecting terminal 300, thereby expanding the display module 400.
[0031] Furthermore, the signal terminal 402 includes a first interface terminal 421 and a second interface terminal 422. The first interface terminal 421 and the second interface terminal 422 are respectively disposed at both ends of the substrate 403 and connected in series with each group of substrates 403. The second interface terminal 422 is connected to the first interface terminal 421 on the adjacent display module 400 through a connecting terminal 300. Specifically, the signal terminal 402 is used to transmit control signals from the signal module 200 to the substrate 403 of each display module 400. The signal terminal 402 can be a thin-diameter copper conductor, a shielded cable, or a tin-plated wire. The specific structure can be selected according to the signal interface requirements of the control system, which is well known to those skilled in the art, and therefore will not be described in detail in this embodiment.
[0032] The substrate 403 has circular holes at both ends. The ends of the first interface terminal 421 and the second interface terminal 422 are soldered into the circular holes and connected to the PCB pads on the substrate 403. At the same time, within the same group of display modules 400, the first interface terminal 421 and the second interface terminal 422 connect multiple groups of substrates 403 in series to form a stable and continuous signal path within the display module 400. In two adjacent groups of display modules 400, the two adjacent groups of first interface terminals 421 and second interface terminals 422 are connected through connecting terminals 300 to form a stable and continuous signal path between the display modules 400.
[0033] Furthermore, the display subunit 001 also includes a support crossbar 500. Multiple sets of display modules 400 are arranged along the second direction. The support crossbar 500 is fixed along the second direction to the connection terminals 300 of two adjacent sets of display modules 400. Each connection terminal 300 has a mounting groove 306 along the second direction. Both ends of the support crossbar 500 are welded into the adjacent mounting grooves 306. Specifically, the support crossbar 500 is disposed within the mounting grooves 306 of the connection terminals 300 to connect two adjacent sets of display modules 400 arranged along the second direction. One end of the support crossbar is inserted into the mounting groove 306 of the first set of connection terminals 300, and the other end is inserted into the mounting groove 306 of the adjacent second set of connection terminals 300. It is electrically connected and mechanically fixed to the groove wall by soldering or mechanical fastening.
[0034] By installing support crossbars 500 between each column of display modules 400, a rigid connection between the modules in the second direction is achieved. This allows the entire group of display modules 400 to form a stable cubic or multi-dimensional spatial structure after assembly, enhancing the overall stability and deformation resistance of the entire display device. It also forms a three-dimensional frame structure with strong impact resistance during external loads or transportation. The support crossbars 500, as the connecting component, can be shaped into smooth bars, threaded bars, or hollow tubes, depending on assembly requirements.
[0035] Furthermore, the connecting terminal 300 is provided with mounting holes 303 along a third direction, and fasteners 304 are provided on the mounting holes 303. The fasteners 304 are used to fix the conductive terminals 401, signal terminals 402, and support crossbars 500 to the connecting terminal 300. Specifically, the mounting holes 303 are provided with internal threads, which engage with the fasteners 304 to provide lateral mechanical fixation of the conductive terminals 401, signal terminals 402, and support crossbars 500, ensuring that the fasteners 304 have good locking force after installation, thereby stably fixing the conductive terminals 401, signal terminals 402, and support crossbars 500 inserted into the connecting terminal 300. After fastening, the conductive terminals 401, signal terminals 402, and support crossbars 500 are then fixed to the connecting terminal 300 by welding, forming a strong mechanical connection and ensuring the stability and rigidity of the cubic structure of the LED display. Fastener 304 preferably uses headless hex socket screws, which are suitable for space-constrained assembly environments due to their concealed head and compact structure, and can be easily installed and removed using an Allen wrench.
[0036] Furthermore, an insulating sleeve 305 is embedded in the inner wall of the mounting groove 306, which provides insulation protection for the support crossbar 500. Specifically, the insulating sleeve 305 is embedded in the inner wall of the mounting groove 306 of the connecting terminal 300 to provide electrical insulation protection for the inserted support crossbar 500, preventing short circuits or leakage caused by direct contact between the conductive terminal 401 or signal terminal 402 and the metal of the connecting terminal 300. The insulating sleeve 305 is preferably made of industrial-grade plastic tubing, which has good electrical insulation properties, high temperature resistance, and mechanical flexibility, and can adapt to the usage requirements of the display module 400 in different environments. The inner diameter of the plastic tubing is tightly fitted with the outer diameter of the support crossbar 500 to ensure the stable position of the conductive terminal 401 or signal terminal 402 within the sleeve, avoiding relative displacement caused by vibration or mechanical impact, thereby maintaining the safety and stability of the electrical connection.
[0037] Furthermore, viewed from the first direction, a set of sidewalls extending along the third direction of the substrate 403 have a stepped cross-sectional structure 431. Specifically, the stepped cross-sectional structure 431 increases the surface area of the sidewalls of the substrate 403, effectively improving the heat dissipation capacity of the substrate 403, promoting the rapid conduction and dissipation of heat generated when the LED light-emitting unit 404 is working, and avoiding luminous efficiency decay or shortened component life due to overheating.
[0038] In summary, the LED display light cube provided in this embodiment enables flexible adjustment of the light cube size according to different usage scenarios.
[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
