Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides an LED display screen, which includes at least one LED module, and the LED module includes a PCB board 101 and several LED units 104 mounted on the PCB board.

[0028] In the production process, LED light-emitting diodes of different colors can be produced according to the different materials of the LED chip, and the LED light-emitting diodes of different colors are produced in batches, and the same package can be used to make LED light-emitting diodes of the same shape and size. LED light-emitting diodes, the LED light-emitting diodes of the same color are classified by a spectroscopic color separation machine, and LED light-emitting diodes of various colors and grades can be obtained.

[0029] For example, in any LED module that constitutes the LED display screen of this embodiment, any LED unit 104 includes one or more LED light-emitting diodes, and each LED light-emitting diode is an LED light-emitting diode obtain...

Embodiment 2

[0051] Such as figure 2 As shown, on the basis of the above examples, a light concentrating layer 201 is further provided on the surface of the concave portion, and the light concentrating layer 201 is used to concentrate the light emitted from its corresponding LED unit. The light-gathering layer 201 is used to gather the light irradiated on the concave portion on the notch 105 of the concave portion, and concentrate each light to the outside through the notch 105, so that the light on the light-emitting surface of each LED unit is more concentrated, The brightness of the light is enhanced.

[0052] For example, the light concentrating layer 201 is a reflective concentrating mirror with a hollow cavity, a light outlet, and a spherical or ellipsoid inner surface, and the light concentrating layer is disposed on the surface of the concave portion. In this way, the light emitted from the LED point in the direction of the non-light-emitting surface can be effectively reflected ...

Embodiment 3

[0058] Such as image 3 As shown, on the basis of the above, each LED unit 104 includes at least one LED light-emitting diode, such as, including one or more red LED light-emitting diodes R, one or more green LED light-emitting diodes G and one or more blue LED light-emitting diodes LED light-emitting diode B, all LED light-emitting diodes are surface-mounted LED light-emitting diodes, surface-mounted LED light-emitting diodes have high brightness, large viewing angle, good flatness, strong reliability and consistency, and can be used for lighter PCB board and reflective layer materials, the reflective layer needs to be filled with less epoxy resin, and the heavy carbon steel material pins are removed. By reducing the size and weight, the weight of the product can be easily reduced by half.

[0059] Moreover, each LED light-emitting diode in each LED unit can be integrated and packaged, so that the volume of the LED unit is smaller, the light is more concentrated, and the disp...

Abstract

The invention discloses an LED display screen, which comprises at least one LED module, wherein the LED module comprises a PCB board and a plurality of LED units; LEDs with various colors and the same quantity are arranged on the LED units, in addition, in each LED unit, the arrangement modes of the LEDs with various colors are the same; LEDs with the same color are arranged into LEDs of the sameseparation file or adjacent separation files; each LED unit on the PCB board is provided with a concave part correspondingly; each LED unit is completely accommodated into the corresponding concave part, and gives out light rays through a concave port of each concave part; and the surface of the LED module is also provided with a black waterproof layer, and the surface of the black waterproof layer is also provided with a photocatalytic layer. The LED display screen has even display and good display effect; and no crosstalk exists among the LED units, in addition, the LED module can automatically clean and has no influence on the display effect when being used for long time.

Description

technical field [0001] The present invention relates to an LED illuminating device, in particular to an LED display screen. Background technique [0002] In the prior art, due to the influence of various conditions during the production process of each LED lamp, there will inevitably be differences. [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 manufacturers will not store a large amount of goods in production, and it is difficult for light screen or display manufacturers to buy the same precision. LED lights. [0004] Due to the differences in chromaticity and brightn...
