Problems solved by technology

[0003] Generally, the flexible display screen can be installed by hanging alone. Since the connecting lines of the flexible display screen are soft wires, and there is a certain transparent distance between the LED light-emitting diodes, if the hanging installation method is used separately, the installed display screen It will be easily affected by external influences, such as natural wind, or various collisions or vibrations, and become unstable, and easily damage various components
If the flexible display is fixed on a conventional fixed frame, since the conventional fixed frame is rigid and not foldable, the foldability function of the flexible display will be lost

Embodiment 1

[0044] like Figure 1a and Figure 1b As shown, in the present invention, the LED device includes an LED module and a frame for fixing the LED module. The LED module can be directly fixed on the frame, for example, by winding wires, or fixing on the frame by binding.

[0045] The LED module includes several LED units 105, and the several LED units 105 are connected to each other through wires 106 and form a network structure. The LED units can be connected in a straight line, in a triangle, in a square, or in other ways, that is, the connected LED units form a straight line, a triangle, a quadrangle or other shapes, as long as each The LED units can be connected to each other to form a network structure.

[0046] The circuit 106 includes at least one power supply positive line, at least one power supply negative line and at least one signal line. Each power supply positive line and each power supply negative line are used to provide voltage for the LED module, and each signa...

Embodiment 2

[0054] Such as Figure 1a , Figure 1b and image 3 As shown, on the basis of Embodiment 1, the fixing unit and the fixing position where the two independent parts are connected can also be configured as a screw connection structure. For example, the independent part 101 is a metal bar 101 with a quadrangular longitudinal section, such as a rectangular metal bar. The independent part 102 is adjacent to the independent part 101 and the independent part 102 is a metal bar 102 with a circular cross section.

[0055] One side of the independent part 101 is provided with a through hole 203, and the shape and size of the through hole 203 correspond to the shape and size of the cross section of the independent part 102, that is, the through hole 203 is also circular, and the area of ​​the through hole is greater than or equal to that of the cross section of the independent part 102. area. The end of the independent part 102 is set as a screw rod, and the screw rod is provided with ...

Embodiment 3

[0058] Such as Figure 4a and Figure 4b As shown, on the basis of Embodiment 1 or Embodiment 2, the frame of the LED device is set as a frame formed by four sides, and the frame includes an independent part 101, an independent part 102, an independent part 103 and an independent part 104. The independent part 101, the independent The part 102 , the independent part 103 and the independent part 104 are fixedly connected to each other through matching fixing units and fixing positions to form a quadrangular LED device. For each independent part constituting the frame, a fixing unit may be provided at both ends of half of the independent parts, and a fixing position may be provided at both ends of the remaining half of the independent parts.

[0059] For example, the two ends of the independent part 101 and the independent part 103 are respectively provided with a fixing unit, and the two ends of the independent part 102 and the independent part 104 are respectively provided wi...

Abstract

The invention discloses an LED device and an LED display screen, wherein, the LED device comprises an LED module and a framework; the LED module is formed by the connection of a plurality of LED units through at least one electric power source positive wire, at least one electric power source cathode wire and at least one signal wire and is fixed on the framework; each LED unit comprises at leastone LED and a controlling module thereof; the framework consists of at least three independent parts and the first end of one independent part thereof is provided with a fixing unit; the second end of another independent part that is connected with the first end of the independent part is correspondingly provided with a fixing place which is matched with the fixing unit; and all independent partsare fixedly connected mutually through one fixing unit and one fixing place respectively so as to form the framework. One LED flexible display screen can consist of one or a plurality of LED devices.The invention has the advantages of stable installation and convenient transportation and carry.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to an LED device and a LED flexible display screen composed of the device. Background technique [0002] In the LED industry, LED flexible displays are generally formed by connecting several LED light-emitting diodes to each other through each power supply positive line, each power supply negative line and each signal line. It can be folded arbitrarily, the volume can be the smallest, and it is very convenient to transport and carry. And because the LED light-emitting diodes are only connected by lines, the permeability between the LED light-emitting diodes is very good, and a very good heat dissipation effect can be obtained without installing a heat sink, and due to the good permeability, when installed on the building curtain wall , does not affect the visual range viewed from the outside of the building. Various flexible display screens can display various animation effects th...
