Abstract
The utility model discloses an anti-interference LED (Light Emitting Diode) display screen. The anti-interference LED display screen comprises an LED module, wherein the LED module is formed by a PCB (Printed Circuit Board) and a plurality of LED units which are arranged on the PCB in sequence, the side surface of the PCB which is provided with the LED units is provided with a plurality of concave pits, the cross sections of the concave pits are of parabola shapes, the height of the concave pits is larggreater than that of the LED units, the arrangement mode of the concave pits is the same as that of the LED units, each concave pit corresponds to one LED unit, the LED units are fixedly arranged at the bottom parts of the concave pits, and the side surface of the PCB is provided with an anti-interference layer of which the shape and the size are the same as those of the PCB. Due to the adoption of the technical scheme, the LED units are fixedly arranged in the concave pits, the concave pits can be used for protecting and isolating the LED units, the LED units can be avoided from being damaged due to the collision during the processes of transporting, installing and using, the interference between among the LED units can be prevented at the same time, and the problem that the display effects of the LED units are affected by the interference is prevented from happening.
Description
Technical field
The utility model belongs to the LED display technical field, is specifically related to a kind of anti-tampering LED display.
Background technology
Development along with the LED technology, the application of LED display is also more and more extensive, especially outdoor display screen is widely used in station, harbour, airport, market, hospital, bank and other public place, is used for display graphics, literal, letter and various animation.Existing LED display generally comprises some LED unit of arranged in sequence on pcb board and the described pcb board, and the spacing on the pcb board between each LED unit is very little, disturbs easily between the LED unit, affects display effect.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of anti-tampering LED display is provided, and avoids causing affecting the problem of display effect because of phase mutual interference between the LED unit.
The technical scheme that the utility model adopts is: a kind of anti-tampering LED display, comprise led module, this led module is by some LED cell formations of arranged in sequence on a pcb board and the described pcb board, the side that is provided with the LED unit on the described pcb board is provided with some pits, the xsect of described pit is parabola shaped, and the height of pit is greater than the height of LED unit, the arrangement mode of described pit is identical with the arrangement mode of described LED unit, and corresponding LED unit of each pit, described LED is fixed in pit bottom in the unit, and described pcb board side is provided with and its shape, the anti-interference layer that size is identical.
As preferably, described pit surface is provided with light collecting layer.
As preferably, described anti-interference layer is the black thin film layer.
The beneficial effects of the utility model are: because the utility model adopts such scheme; the LED unit is fixed in the pit; pit plays protection and buffer action to it; can avoid each LED unit in transportation, installation and use procedure, to damage because of collision; prevent simultaneously the interference between each LED unit, avoid it to affect the problem of display effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, pcb board; 2, LED unit; 3, pit; 4, light collecting layer; 5, anti-interference layer.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of anti-tampering LED display, comprise led module, this led module is made of some LED unit 2 of arranged in sequence on a pcb board 1 and the described pcb board 1, the side that is provided with LED unit 2 on the described pcb board 1 is provided with some pits 3, the xsect of described pit 3 is parabola shaped, and the height of pit 3 is greater than the height of LED unit 2, the arrangement mode of described pit 3 is identical with the arrangement mode of described LED unit 2, and each pit 3 corresponding LED unit 2, described LED unit 2 is fixed in pit 3 bottoms, described pit 3 surfaces are provided with light collecting layer 4, the light that each LED unit 2 is penetrated is more concentrated, and light luminance is stronger, and described pcb board 1 side is provided with and its shape, the anti-interference layer 5 that size is identical, described anti-interference layer 5 is the black thin film layer, black has good light absorptive, can absorb the light of penetrating on pcb board, makes the LED unit avoid the interference of external light.
Because the utility model adopts such scheme; LED unit 2 is fixed in the pit 3; pit 3 plays protection and buffer action to it; can avoid each LED unit 2 in transportation, installation and use procedure, to damage because of collision; prevent simultaneously the interference between each LED unit 2, avoid it to affect the problem of display effect.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, the equivalence of namely doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
