[embodiment]
The structure of the LED display of the utility model embodiment arc-shaped bend as shown in Figures 1 to 7, comprise the flexible joint plate 1 that many lamp bars 100 (accompanying drawing only illustrates two lamp bars 100) and lateral connection lamp bar 100 two pieces are plate shaped, two blocks of flexible joint plates 1 are arranged in the two ends of lamp bar 100, and flexible joint plate 1 is fixed on the front of lamp bar 100.
Flexible joint plate 1 can be that elastic plate or polylith rigid plate are hinged formation.
Lamp bar 100 comprises lamp bar housing 2 and LED circuit board 3, and lamp bar housing 2 is flute profile, comprises two blocks of side plates 201 and 8 web joint fixed legs 202.
Flexible joint plate 1 screw 5 is fixed on the end face of web joint fixed leg 202.Web joint fixed leg 202 is arranged in the groove of the inner side of side plate 201, and the end face of web joint fixed leg 202 is higher than the end face of side plate 201.
Like this, having clearance delta between the bottom surface of flexible joint plate 1 and the end face of side plate 201, is slot milling when flexible flexible joint plate 1 bends.
LED circuit board 3 is packed in lamp bar housing 2, and the light-emitting component 301 on circuit board 3 is higher than the end face of web joint fixed leg 202, and the height of flexible joint plate 1 is between the end face and the end face of light-emitting component 301 of lamp bar 100.Between adjacent lamp bar during angle change, the axis of flexible joint plate 1 flexural center 0 luminescent center that is best and light-emitting component 301 is in same plane.
Flexible joint plate 1 is straight thin plate porous structural, comprises multiple lamp hole 101, and the light-emitting component 301 at lamp bar 100 two ends passes the lamp hole 101 of flexible joint plate 1.
The hole heart of lamp hole 101 is apart from identical with the spacing of LED light-emitting component 301, flexible joint plate 1 is pressed in above substrate 101, use screw and lamp bar 1 to fix, and the flexible deformation center of flexible joint plate 1 and the luminescent center of LED light-emitting component 301 can be made to be in same level by the height of adjustment lamp bar upper junction plate fixed leg 202.All lamp bars 100 utilize many flexible joint plates 1 to couple together, and flexible joint plate 1 is uniformly distributed in the front of lamp bar 100.
As shown in Figures 5 to 7, in a straightened condition, the distance on two adjacent lamps bars between LED light-emitting component 301 is 7.94mm; Be bent downwardly in the middle part of the LED display of arc-shaped bend, when two adjacent lamps bars rotate 20 ° relatively, the distance on two adjacent lamps bars between LED light-emitting component 301 is 7.82mm; Be bent upwards in the middle part of the LED display of arc-shaped bend, when two adjacent lamps bars rotate 10 ° relatively, the distance on two adjacent lamps bars between LED light-emitting component 301 is 7.91mm; , compared with straightened condition, the distance on two adjacent lamps bars between LED light-emitting component 301 there is no and changes.
Because the flexural center O of flexible joint plate 1 is just on the line of adjacent light emitting element 301 luminescent center; when the LED display of arc-shaped bend bends; distance between adjacent lamps bar light-emitting component 301 can not change substantially; completely avoid to draw close because of light-emitting component or point to turn on light and between bar, occur the defect of the abnormal show such as bright band or black-tape, ensure that the quality of LED display.
The above embodiment of the utility model can meet the LED display flexible joining mechanism of little dot spacing arc-shaped bend, this structure can meet in turning axle space minimum between point space distance LED display screen lamp bar 100, and be in same level with light-emitting component 301, between lamp bar 100 luminous point caused when can realize flexible deformation preferably, dot spacing is constant, thus display effect good when the LED display realizing Small Distance arc-shaped bend bends.
