Embodiment 1

[0024] Such as figure 1 As shown, the present embodiment provides a precise LED module, which includes a PCB board 101 , a power line 105 , a signal line 104 , at least one set of LED light emitting diodes 102 and a drive control module thereof.

[0025] On the PCB board 101, other electronic components can also be set according to actual needs, for example, a resistor is set to prevent a certain component from burning out due to excessive current, or a capacitor is set; the power line 105 is used for the PCB The electronic components on the board 101 provide a voltage source; a ground wire 103 is also arranged on the PCB board 101, and the ground wire 103 is used to lead the redundant current or strong potential generated by the PCB board 101 into the earth. In addition, the ground wire 103 Multiple bars can also be set according to actual needs to prevent excess current or strong electric potential from causing harm to the human body.

[0026] At least one group of LED ligh...

Embodiment 2

[0035] Such as figure 2 As shown, on the basis of the above-mentioned examples, in the LED precision module, three groups of LED light-emitting diodes are provided, which are respectively a red LED light-emitting diode group, a green LED light-emitting diode group and a blue LED light-emitting diode group; and, From each group of LED light-emitting diodes, 2 red LED light-emitting diodes, 1 green LED light-emitting diode and 1 blue LED light-emitting diode are used to form an LED light-emitting unit.

[0036] In the formed LED light-emitting unit, each LED light-emitting diode is arranged in a quadrangular shape. In this way, the light emitted by the LED light-emitting diodes of various colors in each LED light-emitting unit can be made more uniform. That is, the ratio of red: green: blue is set to 2:1:1, and a red LED light-emitting diode is added in each LED light-emitting unit, so that the colors can cooperate better with each other, and the light emitted is more in line ...

Embodiment 3

[0038] On the basis of the above examples, the shape of the precise LED module can be set as a right triangle, an isosceles triangle, a regular triangle or a combination thereof; for example, a rhombus, a square or a regular hexagon, etc.; or, it can be set as a square, a regular Pentagon, regular hexagon, ... regular 100-gon, etc., because the sides of the regular polygon are equal, therefore, the exact shape of each LED module is set to a regular polygon with more than three sides, so that the assembly When forming an LED display, the assembly size of the LED display is more flexible, and the combination method is more convenient; moreover, the shape and size of each LED precise module can be set according to the number of LED light-emitting diodes of a grade after the precise grade selection. For example, the shape of each precise LED module is set to be a square, which can meet the assembly of most regular LED display screens, or the shape of each precise LED module is set ...

Abstract

The invention discloses an LED accurate module which comprises a PCB board, a power line, a signal line, at least a group of LED light emitting diodes and a driving control module, LED light emitting diodes with the same brightness, the same color, the same wavelength, the same encapsulation, the same shape and the same size are arranged in any one group of LED light emitting diodes, and the LED light emitting diodes have the same separating level. The LED accurate module can be conveniently stored and managed, and an LED whole screen formed by the LED accurate module has even display and good displaying effect, can be quickly assembled and supply stocks.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to an LED precision module and an LED display device formed by assembling the LED precision module. Background technique [0002] In the prior art, due to the influence of various conditions in the production process of each LED lamp, there will inevitably be differences. However, each LED lamp can be classified by a spectroscopic and color separation machine, and the spectroscopic and color separation accuracy is very high. [0003] Since different customers have different requirements for the accuracy of each LED lamp, and the usage of each LED lamp is also different, therefore, the general lamp screen or display screen manufacturer, after receiving the order from the customer, then produces LED lamps. Manufacturers purchase LED lights. Since LED lights are relatively unstable during storage, they are prone to damage due to vibration, collision, etc. Therefore, LED light manufact...
