Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a display unit, including 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 constituting a display unit 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 obtained by using a spectrosco...

Embodiment 2

[0048] 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.

[0049] 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

[0055] 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.

[0056] 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 a display unit. The display unit comprises at least one LED (Light Emitting Diode) module, wherein each LED module comprises a PCB board (Printed Circuit Board) and a plurality of LED units; LEDs with various colors and the same quantity are arranged on any LED unit, and in each LED unit, the arrangement modes of the LEDs with various colors are the same; LEDs are arranged into LEDs of the same separation file or adjacent separation files; each LED unit is provided with a concave part correspondingly; each LED unit is completely accommodated into the corresponding concave part, and gives out light rays through each concave port; the surface of the LED module is provided with a black waterproof layer, and the surface of the black waterproof layer is further provided with a photocatalytic layer; each PCB board is further provided with a heat dissipation layer, and each heat dissipation layer and each LED unit are arranged on the two sides with opposite directions of the PCB board respectively. The display unit has uniform display and good display effect; and no crosstalk exists among the LED units, and the LED module can automatically clean and has no influence on the display effect when being used for a long time.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to a display unit. 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 vibrations, collisions, etc. Precision LED lights. [0004] Due to the differences in chromaticity and brightness of LED lights of various grades, lamp screen manufacturers generally do not directly use these high-precision lights to directly make screens after obtaining these lights, b...
