Abstract

The invention discloses an LED hollow screen which comprises a PCB and LED lamps, wherein the LED lamps are regularly arranged on one side of the PCB, the PCB is integrally stamped by any number of fine stamping dies, PCB hollow holes are regularly arranged on the PCB, a preset distance is reserved between the PCB hollow holes, and the PCB hollow holes are regularly polygonal. The invention aims to provide permeability and improve the heat dissipation effect of the device.

Description

LED fretwork screen

Technical Field

The invention relates to the field of LED screens, in particular to an LED hollow screen.

Background

Grid screens refer to an emerging LED display screen which is formed by light bars into a grid shape in recent years, and the grid screen is another name of the light bar screen. Because the shape is hollow and grid, the LED grid screen is also called as an LED grid screen, a hollow screen and the like by people in the industry. This kind of display screen mainly is applied to outdoor wall body, glass curtain wall, and the building top still includes outdoor antiaircraft gun, sightseeing elevator etc. and the strideing nature design of grid screen has broken through traditional LED display screen to a great deal of restriction of building body wall for the engineering becomes more nimble, more selective, more wandering and more surplus, but, because LED fretwork screen density is big, the permeability is relatively poor, causes the heat to give off slowly easily, influences life.

An effective solution to the problems in the related art has not been proposed yet.

Disclosure of Invention

The invention aims to provide an LED hollow screen to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a LED fretwork screen, includes PCB board and LED lamp, the LED lamp rule sets up in PCB board one side, the PCB board has arbitrary quantity fine blanking mould punching press to become integrative, the rule is provided with PCB board fretwork hole site on the PCB board, be predetermined distance between the PCB board fretwork hole site, PCB board fretwork hole site just is the regular multilateral type.

Furthermore, the PCB is formed by punching four sets of fine blanking dies.

Further, the size of the PCB module is 500mm x 125 mm.

Further, the transverse spacing of the PCB board hollow hole positions is 3.91mm, and the longitudinal spacing of the PCB board hollow hole positions is 7.82 mm.

Furthermore, the hollowed-out hole sites are rectangular and penetrate through the PCB.

Compared with the prior art, the invention has the following beneficial effects: according to the invention, the hollowed-out intervals are arranged at the preset intervals, so that the permeability can be improved, and the heat dissipation is accelerated.
