Problems solved by technology

However, since each LED light box is equipped with terminals for power cables and signal cables, LED light boxes need to be connected by wiring to connect power cables and signal cables. Therefore, at the construction site of the LED display, A large number of power lines and signal lines are required. When the wiring is improper, it is easy to cause the danger of leakage, and it is not beautiful, and when there is a problem with the wiring of an LED light box, the entire LED display will cause graphics loss and cannot work normally.

Embodiment 1

[0025] This embodiment provides an LED display screen, which can be mainly used outdoors. The LED display screen includes: an LED light box combination, and a conductive module and a signal transmission module. The LED light boxes can be fixed by various available fixing methods, such as fastening through the buckle structure or plugging in the male and female plugs, etc. After the LED light boxes are structurally fixed, the LED light boxes need to take into account the power supply and electrical signaling. Therefore, the LED display screen also needs to include: a conductive module and a signal transmission module connected to the cables of the LED light box.

[0026] The LED light box combination mainly includes a first LED light box and a second LED light box. The first LED light box is opposite to the second LED light box. The first LED light box is located above the second LED light box. Several LED light boxes can be accumulated and combined, such as figure 1 As shown...

Embodiment 2

[0032] The main difference between this embodiment and the above-mentioned embodiments is that: the first LED box and the second LED box can also be arranged in a way of being adjacent to each other on the left and right.

Embodiment 3

[0034] The main difference between this embodiment and the above-mentioned embodiments is that: the first conductive terminal 213 and the second conductive terminal 513 can adopt other matching structures, for example, the first conductive terminal 213 and the second conductive terminal 513 are both cubes, and the first conductive terminal 213 is due to gravity and the second conductive terminal 513 is due to spring force. When the first LED light box and the second LED light box are docked, the first conductive terminal 213 and the second conductive terminal 513 will contact, thereby realizing electrical connection.

Abstract

The invention discloses an LED lamp box, an LED lamp box combination and an LED display screen. Connecting boxes used for being in butt joint with other LED lamp boxes are arranged on one side of the LED lamp box, when the LED lamp boxes are connected with each other in an abutting-against mode, conductive terminals inside the connecting boxes will be in contact with each other to achieve electrical connection of adjacent LED lamp boxes, and power connection and signal connection between adjacent LED lamp boxes are achieved. Therefore, no built-in connecting cable exists between the LED lamp boxes, rapid disassembly and rapid assembly are guaranteed, and safety, attractiveness, cleanness and tidiness of connection are achieved.

Description

technical field [0001] The present application relates to the field of light emitting diodes, in particular to an LED light box combination and an LED display screen. Background technique [0002] A light emitting diode (Light Emitting Diode, LED) is a semiconductor electronic component capable of emitting light, which can convert electrical energy into light energy output. Because of its high brightness and illuminance and low power consumption, it is widely used in lighting, display and other fields. [0003] On a large outdoor LED display, it is generally formed by combining multiple LED light boxes. Each LED light box will lead out the power cable to the power supply, and will also lead out the signal cable to the control terminal, so that each LED light box will be powered by the power supply, and the control terminal will output the control signal to the signal cable to be controlled. After receiving the control signal through the signal cable, the LED light box real...
