Fig. 1 is a side view of the LED lamp panel 100, and fig. 2 is a bottom view of the LED lamp panel 100. Fig. 3 is a partially enlarged view of a point a in fig. 1. Referring to fig. 1 to 3, an LED lamp panel 100 according to an embodiment of the present invention includes a substrate 101, and a front surface 101a of the substrate 101 is provided with a plurality of beads 102 at intervals. The edge of the substrate 101 is provided with at least one first splicing part 103 which can be spliced with other LED lamp panels. The back surface 101b of the substrate 101 has a groove 104 at the first joint 103, and the groove 104 crosses the first joint 103 along the length direction of the first joint 103 (the direction perpendicular to the paper surface in fig. 1).
Specifically, since the substrate 101 of the LED lamp panel 100 has a thickness of, for example, about 2mm, when the distance between two adjacent LED lamp panels 100 is reduced, the back surface 101b of the substrate 101 may interfere in order to splice into an outer arc. In order to prevent the interference of the back surfaces 101b of the substrates 101 of the LED lamp panels 100 joined to each other, the distance between the two LED lamp panels 100 has to be increased. When the distance between the two LED lamp panels 100 is greater than the distance between the lamp beads 102 on the substrate 101, the distance between the lamp beads 102 on the edges of the two substrates 101 is greater than the distance between the lamp beads 102 on the substrate 101, and a dark line may be generated at the joint to affect the display effect.
In this embodiment, because set up slot part 104 in the back 101b department of base plate 101, can realize when having an LED display screen 200 of this kind of LED lamp plate 100 and another LED display screen 200 splice into the outer arc, can reduce the distance between two LED lamp plates 100 of mutual concatenation, and then reduce the distance between the lamp pearl 102 of two lamp plates of mutual concatenation, from this, can prevent to produce the dark line and lead to influencing the display effect in concatenation department.
In some embodiments, the substrate 101 has a square shape, and the first splicing portion 103 includes two portions respectively disposed at edges of two opposite sides of the substrate 101. The groove 104 crosses the first splice 103 along the longitudinal direction of the first splice 103 to penetrate both sides (both sides in the longitudinal direction in fig. 2) of the substrate 101 adjacent to the first splice 103. Therefore, the thickness of the substrate 101 at the position of the first splicing part 103 is smaller than the thickness of the other positions of the substrate 101, so that the angle of the outer arc selectable when the LED lamp panels 100 are spliced at the position of the first splicing part 103 can be enlarged, and the distance between the two LED lamp panels 100 at the splicing position can be reduced. The groove portion 104 may be processed from the back surface 101b of the substrate 101, for example, grooving processing may be performed by CNC. In addition, the grooves 104 may be formed by washing off the plating layer with a chemical solvent when the substrate 101 is manufactured.
In some embodiments, the groove portion 104 has a first surface 105 parallel to the front surface 101a of the substrate 101, and the distance S1 from the front surface 101a of the substrate 101 to the first surface 105 ranges from 0.2mm to 0.6 mm. By setting the distance S1 from the front surface 101a of the substrate 101 to the first surface 105 in the range of 0.2mm to 0.6mm, the thickness of the first splicing part 103 can be reduced on the premise of ensuring the function of the substrate 101, and therefore, the angle of the outer arc selectable when the LED lamp panels 100 are spliced at the position of the first splicing part 103 can be further enlarged, and the distance between the two LED lamp panels 100 at the splicing position can be reduced.
In some embodiments, the first splicing portion 103 is provided with a first splicing surface 106, the slot portion 104 has a second surface 107 perpendicular to the first surface 105, and a distance S2 from the first splicing surface 106 to the second surface 107 is greater than a distance S3 from the back surface 101b of the substrate 101 to the first surface 105. By setting the distance S2 from the first splicing surface 106 to the second surface 107 of the groove 104 to be greater than the distance S3 from the back surface 101b of the substrate 101 to the first surface 105, it is possible to prevent the boundary 108 between the second surface 107 and the back surface 101b on one substrate 101 and the boundary 108 between the second surface 107 and the back surface 101b on the other substrate 101 from interfering when the LED lamp panel 100 is spliced at the position of the first splicing portion 103. From this, can further enlarge the angle of the outer arc that LED lamp plate 100 can select when splicing in the position department of first concatenation portion 103 to can reduce the distance of two LED lamp plates 100 in concatenation position department.
In some embodiments, the beads 102 are arranged in an array on the front surface 101a of the substrate 101, and the distance S4 between the centers of two adjacent beads 102 is less than 1.8 mm. Specifically, the beads 102 may be mounted on the substrate 101 by a method known in the art, such as soldering, and the beads 102 may be arranged in an array by a method known in the art. The distance S4 between the centers of the lamp beads 102 can be selected to be, for example, 1.8mm, 1.5mm, 1.2mm, or 0.9 mm. In this embodiment, since the distance between the two LED lamp panels 100 at the splicing position is reduced, the LED lamp panel 100 having a smaller interval of the bead 102 distance can be designed, so that the display effect of the LED lamp panel 100 can be further enhanced.
Fig. 4 is a side view of the LED display panel 200, fig. 5 is a partial enlarged view of a portion B in fig. 4, and referring to fig. 4 and 5, the LED lamp panel 100 can be used on the LED display panel 200. Specifically, the LED display screen 200 according to the second embodiment of the present invention includes: the LED lamp panel 100 comprises a box body 201 and the LED lamp panel 100, wherein the LED lamp panel 100 is installed on the box body 201.
In this embodiment, because the groove 104 is formed in the back 101b of the substrate 101, when the LED display screen 200 is spliced into an outer arc, the distance between the two LED lamp panels 100 spliced with each other can be reduced, and then the distance between the lamp beads 102 of the two lamp panels spliced with each other is reduced, so that the influence on the display effect caused by the dark line generated in the spliced position can be prevented.
It is conceivable that the LED lamp panel 100 is fixedly mounted on the box 201 by a magnet (not shown). In addition, a power supply (not shown), a driving assembly (not shown), various plugs (not shown), and the like of the LED lamp panel 100 may be accommodated in the case 201, thereby conveniently controlling the LED lamp panel 100.
Fig. 6 is a side view of the tiled screen 300, fig. 7 is a partial enlarged view of the LED display screen at C in fig. 6, fig. 8 is a partial enlarged view of the LED display screen at D in fig. 7, and referring to fig. 6 to 8, the LED display screens 200 described above can be tiled to form the tiled screen 300. Specifically, the spliced screen 300 according to the embodiment of the third aspect of the present invention includes at least two LED display screens 200, wherein the box 201 of each LED display screen 200 is at least provided with one second spliced portion 202, and the first spliced portion 103 and the second spliced portion 202 are located on the same side; the LED display screens 200 are respectively spliced at the second splicing portions 202, so that the LED lamp panels 100 are respectively spliced at the first splicing portions 103.
In this embodiment, since the groove 104 is formed in the back surface 101b of the substrate 101, when the LED display screen 200 is spliced into an outer arc, the distance S5 between the two LED lamp panels 100 that are spliced with each other can be reduced, and then the distance S6 between the lamp beads 102 of the two lamp panels that are spliced with each other is reduced, thereby preventing the display effect from being affected by the dark line generated in the spliced position.
In some embodiments, the LED display screen 200 may be inner arc or outer arc tiled. For example, in some embodiments, the box 201 is provided with a first inclined surface 203 at the second splicing portion 202, and an angle R1 between the first inclined surface 203 and the front surface 101a of the LED lamp panel 100 is greater than 0 ° and smaller than 90 °. At least one box body connecting piece 204 is respectively arranged on each first inclined surface 203, and a second splicing surface 205 is arranged on each box body connecting piece 204. An angle R2 between the second splicing surface 205 and the front surface 101a of the LED lamp panel 100 is greater than 0 ° and less than or equal to 90 °. When the LED display screens 200 are spliced with each other, the second splicing surfaces 205 of the box connectors 204 on the two boxes 201 that are spliced with each other are attached to each other.
Specifically, for example, the angle R1 between the first inclined surface 203 and the front surface 101a of the LED lamp panel 100 may be 45 °. The first bevel 203 may be milled by CNC machining or the like. The tank connector 204 may be locked to the first slope 203 by means of a screw-coupling. And, a plurality of case connectors 204 may be mounted on the first slope 203. The second splicing surface 205 of the box connector 204 is machined directly during machining of the box connector 204, for example, by means of CNC machining. The angle R2 between the second splicing surface 205 and the front surface 101a of the LED lamp panel 100 is determined according to the angle R1 between the first inclined surface 203 and the front surface 101a of the LED lamp panel 100, and the angle R3 between the mounting surface 206 of the box connector 204 mounted to the first inclined surface 203 and the second splicing surface 205. For example, when the angle R1 between the first inclined surface 203 and the front surface 101a of the LED lamp panel 100 is 45 °, the angle R3 between the second splicing surface 205 and the mounting surface 206 of the box connector 204 is greater than 0 ° and less than 45 °. Specifically, for example, when the angle of the outer arc to be spliced is 184 °, the angle R1 between the first inclined surface 203 and the front surface 101a of the LED lamp panel 100 may be set to 45 °, and correspondingly, the angle R3 between the second splicing surface 205 and the mounting surface 206 of the box connector 204 may be set to 43 °, so that the angle R2 between the second splicing surface 205 and the front surface 101a of the LED lamp panel 100 is 88 ° after the box connector 204 is mounted to the first inclined surface 203. When two LED display screens 200 are spliced, the second splicing surfaces 205 of the box connecting pieces 204 on the two boxes 201 which are spliced with each other are attached to each other to form an outer arc surface with an angle of 184 degrees at the LED lamp panel 100, so that the outer arc type splicing of the LED display screens 200 is completed.
Likewise, when the inner arc type splicing is required, for example, when the angle of the inner arc to be spliced is 176 °, the angle R1 between the first inclined surface 203 and the front surface 101a of the LED lamp panel 100 may be set to 45 °, and correspondingly, the angle R3 between the second splicing surface 205 and the mounting surface 206 of the box connector 204 may be set to 47 °, so that the angle R2 between the second splicing surface 205 and the front surface 101a of the LED lamp panel 100 is 92 ° when the box connector 204 is mounted to the first inclined surface 203. When the two LED display screens 200 are spliced, the second splicing surfaces 205 of the box connectors 204 on the two boxes 201 which are spliced with each other are attached to each other to form an inner arc surface with an angle of 176 ° at the LED lamp panel 100, thereby completing the inner arc type splicing of the LED display screens 200.
In addition, when the two LED display screens 200 are spliced to form a 90 ° angle, the box connector 204 can be eliminated, and the first inclined surface 203 of the box 201, which is at 45 °, is used for direct splicing. When the LED display screens 200 are directly spliced into 180 °, the first inclined plane 203 does not need to be processed on the box 201, and the splicing is directly performed by using a lock catch known in the art.
In some embodiments, in order to facilitate the assembly, disassembly and maintenance of the LED lamp panels 100, and prevent the distance between the LED lamp panels 100 of the two LED display screens 200 from being too close to generate bright lines at the joint, thereby affecting the display effect, each of the LED display screens 200 includes at least one gap control 207, the gap control 207 is at least partially accommodated in the groove portion 104, and the gap control 207 protrudes toward the outer side of the substrate 101 compared to the first joint portion 103. When the LED display screens 200 are spliced with each other, the gap controller 207 on one LED display screen 200 abuts against the gap controller 207 on the other LED display screen 200. Specifically, the gap controller 207 may be in a block shape and mounted on the box 201, and after the lamp panels are mounted on the box 201, the gap controller 207 protrudes slightly to the outside of the substrate 101 than the first splicing portion 103 by a distance of, for example, 0.05mm or less, so that the S5 distance between the LED lamp panels 100 of the LED display panels 200 spliced with each other is less than 0.1 mm. In addition, the angle between the surface of the mutual butt joint of gap control 207 and the front surface 101a of LED lamp panel 100 can be set according to the splicing angle of LED display screen 200, thereby ensuring that gap control 207 of LED display screen 200 spliced with each other is mutually attached after LED display screen 200 is spliced. From this, through setting up clearance control 207, can control the distance between two LED lamp plate 100 of LED display screen 200, prevent that its distance is too close and produce the bright line in concatenation department, and then lead to influencing the display effect. Further, it is also possible to prevent a short circuit due to pad contact between the LED lamp panels 100 due to the splicing of the LED display screens 200. Further, when dismantling a LED lamp panel 100 therein, can prevent to collide with adjacent LED lamp panel 100.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the invention and the features of the embodiments may be combined with each other without conflict.
