Abstract
The invention relates to a hollow light-emitting diode (LED) display screen. The hollow LED display screen consists of a fixing frame, a control box and a display part, wherein the display part and the control box are arranged on the fixing frame; the display part is connected with the control box and consists of a plurality of lamp strips; and the lamp strips are connected with the control box by end caps. A hollow gap is formed between two adjacent longitudinal lamp strips; a hollow rate between the two longitudinal lamp strips is over 50 percent; the lamp strips are arranged on lamp strip backboards by V-shaped grooves at the bottoms of the lamp strips; the two ends of each lamp strip backboard are connected with the fixing frame; and the hollow rate between two adjacent longitudinal lamp strip backboards is equal to that between two adjacent longitudinal lamp strips. The hollow LED display screen has a rational structural design, and the hollow rates are designed among the longitudinal lamp strips, over 50 percent of wind load can be released through the hollow gaps among the lamp strips, and the display screen is prevented from being blown down by the pressure of strong wind, so that the service life of the overall display screen is prolonged. Due to the hollow structure designed at unequal intervals of the screen, processing cost can be saved.
Description
Technical field
The present invention relates to a kind of LED display, especially a kind of hollow out formula LED display.
Background technology
At present, existing large LED display screen generally all is lighttight plane formula structure, and all is mounted in the tip position of buildings.Because the weight of LED display integral body is bigger, and do not possess the effect of printing opacity, therefore when running into strong wind, very easily cause collapsing or damaging of display screen, in addition, when display screen collapses, can damage yet buildings.Because the volume of LED display is very big, therefore need ventilations of lowering the temperature of built-in a plurality of fans or air-conditioning, therefore when work, fan or air-conditioning can produce phenomenons such as noise and resonance greatly.Because the quantity of display screen connection wire cable is a lot, and because the defective of project organization, thus these cables be exposed to for a long time also very easily cause in the air get rusty, the burn into short circuit, fault such as open circuit.In addition, controller needs all to show that with each module is connected by data line, power lead that controller and power supply all are independently to be positioned in the casing with power supply, and long term exposure also very easily causes to accumulate dust, get rusty, corrode in air.
Summary of the invention
At the weak point that exists in the problems referred to above, the invention provides a kind of rational in infrastructurely, easy for installation, can effectively alleviate the impulsive force of wind load, the hollow out formula LED display of avoiding display screen to damage.
For achieving the above object, the invention provides a kind of hollow out formula LED display, constitute by fixed mount, control enclosure and display part, described display part and described control enclosure are installed on the described fixed mount, described display part is connected with described control enclosure, and described display part is made of a plurality of lamp bars, is provided with the hollow out gap between two adjacent described vertical lamp bars, hollow out ratio between two described vertical lamp bars is greater than 50%, and described lamp bar is connected with described control enclosure by end cap.
Described lamp bar is installed on the lamp bar backboard, and adjacent two described vertical lamp bar backboards are identical with hollow out ratio between adjacent two described vertical lamp bars.
The two ends of described lamp bar backboard are connected with described fixed mount, be connected with clamping screw by fixed pin between two adjacent described lamp bar backboards, described fixed pin and described clamping screw all are arranged on the edge of described lamp bar backboard, are respectively equipped with at least one at described lamp bar back plate surface and edge and are used to prevent the reinforcement of described lamp bar backboard distortion and the V-type groove a that is used for fixing described lamp bar.
Lower end among the described V-type groove a is provided with lockhole, and described lockhole is arranged on the positive lower end of acute ends in the described V-type groove.
Described end cap is separately positioned on the two ends of described lamp bar, is provided with the V-type groove b of concave shaped in the bottom of described lamp bar, is provided with the projection lock on the sidewall of described V-type groove b.
Described end cap is connected with inserting groove in the described control enclosure by connecting line, and described end cap and described connecting line are integral structure.
Compared with prior art, the present invention has the following advantages:
Hollow out formula LED display provided by the invention, be made of fixed mount, control enclosure and display part, display part and control enclosure are installed on the fixed mount, and the display part is connected with control enclosure, the display part is made of a plurality of lamp bars, and the lamp bar is connected with control enclosure by end cap.Be provided with the hollow out gap between two adjacent vertical lamp bars, hollow out ratio between two vertical lamp bars is greater than 50%, the lamp bar is installed on the lamp bar backboard by the V-type groove of its bottom, the two ends of lamp bar backboard are connected with fixed mount, and adjacent two vertical lamp bar backboards are identical with hollow out ratio between adjacent two vertical lamp bars.Project organization of the present invention is reasonable, in light weight, will adopt the design of hollow out formula longitudinally between the lamp bar, the wind load more than 50% can be discharged by the hollow out spacing between the lamp bar, can avoid display screen under the blast of strong wind, to be blown down, thereby prolong the serviceable life of display screen integral body; Because display screen adopts level and the engraved structure that vertical non-equidistance designs, and is therefore saving processing cost significantly, and also can not produce the phenomenon of distortion to the bigger displaying contents of length and width amplitude; Owing to also reduced the usage quantity of lamp bar, therefore the also corresponding power consumption 80% that reduced has the advantage of low noise and low energy consumption.The present invention is easy for installation, other assembly just can be installed on fixed mount after fixed mount assembling finished successively, because the spacing between the lamp bar backboard is identical, the spacing of therefore installing between the adjacent lamp bar in back is also identical, before assembling, go to measure and calculate spacing between the lamp bar without the installer, can increase substantially packaging efficiency.
