Problems solved by technology

Setting connection units and cascading units in each LED unit can increase the flexibility of each LED unit, but at the same time, it also increases the occupied area and volume of each LED unit. Several LED units will be provided with several connection units and several Cascaded units, the LED product structure is more complex, occupying a large volume, and the product is not beautiful
Moreover, it will be difficult to make a transparent product if a certain number of LED units are installed in a certain volume or area

Embodiment 1

[0025] like figure 1 and figure 2 As shown, the LED unit includes a PCB board 101 and an LED light emitting diode 102 . The LED light emitting diode 102 can be installed on the side of the PCB board 101, also can be installed on the side of the PCB board 101, as long as it does not affect the work of the LED light emitting diode 102; each LED unit is provided with at least one LED light emitting diode 102, LED The light emitting diode 102 may be a red LED light emitting diode, or a blue LED light emitting diode, or a green LED light emitting diode, or a combination of any two of them, or a combination of three.

[0026] The PCB board 101 can be a single-layer board, a double-layer board or a multi-layer board according to actual needs, wherein the multi-layer board is most preferably a 3 to 10-layer PCB board, and each layer of PCB board includes an insulating substrate and a printed circuit board. A conductive pattern layer on an insulating substrate. A single-sided PCB l...

Embodiment 2

[0040] Such as image 3 As shown, a part of the positive power line 201, the negative power line 203 and the control signal line 202 constituting the cascade unit are respectively arranged on the PCB board 101 in each LED unit, and the other part is independently formed into a circuit, that is, the positive power line A part of 201 is set on the PCB board 101, and the other part is used to connect two LED units; a part of the negative power line 203 is set on the PCB board 101, and the other part is used to connect the two LED units; a part of the signal control line 202 is set on the PCB board 101 , the other part is used to connect two LED units; that is, each LED unit is cascaded with each other through a power supply positive line 201, a power supply negative line 203 and a control signal line 202, and two adjacent LED units are connected through a power supply positive line The line 201, a negative power line 203 and a control signal line 202 are connected in three lines....

Embodiment 3

[0042] Such as Figure 4 As shown, on the basis of Embodiment 2, the connecting part between two adjacent LED units, that is, a power supply positive line 201, a power supply negative line 203 and a control signal line 202 three lines of independent line parts, can be respectively in The three independent circuit parts are respectively provided with an insulating outer layer, which can protect the circuit, for example, waterproof and dustproof, and can also prevent short circuit between the circuits. In addition, the three lines can be closely combined to form a multi-strand line 401. The multi-strand line 401 includes part of the power supply positive line 201, part of the power supply negative line 203 and part of the signal control line 202. The three lines are separated by insulating layers. to prevent short circuits. Since the multi-strand line 401 includes three wires, the line is more solid and not easy to disconnect, and the connection is also simpler.

Abstract

The invention discloses an LED device, which comprises at least two LED modules, wherein, each LED module comprises a PCB board, at least one LED light-emitting diode arranged on the PCB board, and a cascade unit; each LED module is connected separately with the cascade unit to achieve cascade. The invention has simple structure, the connection structures between the LED modules are simple, and the occupied size is small.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to an LED device connected by at least two LED units. Background technique [0002] In the LED industry, LED products, such as LED displays, are composed of several LED pixels connected to each other. Each LED pixel can be used as an LED unit, including at least one LED light-emitting diode and a PCB board for installing the LED light-emitting diode. . In the prior art, the connection between LED units is generally realized by setting various connection units, such as setting connection sockets. To achieve independent control of each LED light-emitting diode, so as to achieve effects such as flickering and animation, each LED unit must be equipped with a cascade unit. Setting connection units and cascading units in each LED unit can increase the flexibility of each LED unit, but at the same time, it also increases the occupied area and volume of each LED unit. Several LED units wi...
