Example Embodiment

[0023] Example 1

[0024] Such as figure 1 As shown, this embodiment provides an LED precision module. The LED precision module 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] The PCB board 101 can also be provided with other electronic components according to actual needs, for example, a resistor can be set to prevent a component from being burned out due to excessive current, or a capacitor can be set; the power line 105 is used for the PCB The electronic components on the board 101 provide a voltage source; the PCB board 101 is also provided with a ground wire 103, and the ground wire 103 is used to guide the excess current or strong electric potential generated by the PCB board 101 to the ground. In addition, the ground wire 103 You can also set up more than one according to actual needs to prevent excess current or strong electric potential from causing harm to the h...

[0041] Example 2

[0042] Such as figure 2 As shown, on the basis of the above 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 composed LED light-emitting unit, the LED light-emitting diodes are arranged in a quadrilateral shape. In this way, the light emitted by the LED light-emitting diodes of various colors in each LED light-emitting unit can be more uniform, and because the luminous efficiency of the red LED light-emitting diodes is relatively low, the ratio of the LED light-emitting diodes of each color in each group of LED light-emitting diodes , That is, the ratio of red: gree...

[0044] Example 3

[0045] In the LED precision module described on the basis of the above examples, each LED light-emitting diode can be packaged with 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. It 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 environmentally friendly silicone resin, environmentally 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 sil...

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...
