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

[0042] 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.

[0043] 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

[0045] In the LED precision module based on the above examples, each LED light-emitting diode can be packaged in black silicone resin in addition to the commonly used epoxy resin package.

[0046] Silicone resin is a polyorganosiloxane with a highly cross-linked network structure, which has the dual characteristics of organic resin and inorganic material, and has unique physical and chemical properties. Mainly include: methyl phenyl silicone resin, methyl silicone resin, low phenyl methyl silicone resin, silicone resin emulsion, self-drying silicone resin, high temperature silicone resin, epoxy modified silicone resin, organic Silicone polyester modified resin, self-drying environment-friendly silicone resin, environment-friendly silicone resin, non-stick coating silicone resin, high-gloss silicone resin, benzyl transparent silicone resin, methyl transparent silicone resin, mica bonding Silicone resin, polymethyl silicone resin, amino silicone resin, fluorosilicone resin, sili...

Abstract

The invention discloses a LED precise module; the module comprises a printed circuit board(PCB), a power wire, a signal wire, at least a set of light emitting diode(LED), a drive control module of the set of light emitting diode and a mould matching with the PCB; the LEDs are set with same brightness, same color, consistent wavelength, same package and same shape size in any set of the light LEDs; wherein, each of the LED is the LED with a same way sort and the adjacent way sort of each of the LED; the shape and size of the mould is arranged corresponding to the printed circuit board. The LED display device of the invention is convenient in memory and management. The entire screen of the LED displays uniformly, has a good display effect, and can be assembled and supplied fast.

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...
