What are the installation methods and precautions of outdoor LED display?

 

 

 

 

 

Because of its diversity, the outdoor display screen is also a variety of installation methods, so let's see what specific installation methods are?

 

Hanging installation method:

In fact, the outdoor LED display hanging installation method can also be called cantilever installation, the two are similar, the installation environment and application are similar, the screen body is designed with a box integrated cabinet, suitable for outdoor and semi-outdoor environment installation.

 

 

Floor-mounted installation method:

The floor-mounted installation method is suitable for high-definition display of the small area of the screen, which can be directly on the ground at the bottom of the screen, and can also be modified by slightly fixing and styling the bottom screen.

 

Flush mounting method:

The embedded installation method of outdoor LED display is to embed the entire screen into the wall, and the outdoor LED display surface and the wall surface are kept flat and the same horizontal line, this installation method can be designed with a simple box, and special attention should be paid to the embedded installation method is best maintained before use, and it is necessary to understand clearly from the LED display manufacturer in advance. The embedded installation method of outdoor LED display can also be used indoors, and most of them are used for display models with small spacing and the whole screen display area is not large.

 

Wall mounting method:

This installation method is usually used indoors or semi-outdoors, the screen display area is small, generally does not leave maintenance channel space, the whole screen is removed for maintenance, or made into a folding integrated frame. The outdoor LED display body area is slightly larger, and the front maintenance design is generally adopted (that is, the front maintenance design, usually using the column assembly method).

 

Roof installation method:

Outdoor LED display adopts the roof installation method needs to fully consider the local wind environment, which is more critical, must be able to withstand the wind force, safety is always the first, generally installed with an inclined angle, or the module is designed with an oblique 8 °, mostly used for outdoor advertising display.

 

Supported installation method:

Outdoor LED display is very common to use the support installation method, including a single column, a double column and a creative pillar, etc., this installation method is very common, I believe that users will often see it in reality, the support installation is usually used in highways, highways, communities and other places.

 

Outdoor rental screen hoisting method:

There is also a kind of outdoor LED display for rental series, this series of installations are temporary installations, the focus is on easy installation and easy disassembly; The size of the screen is determined by the ordinary screen. The hoisting screen should not be made larger. THE GENERAL REQUIREMENT IS BELOW 6M*10M. Exceptions are made for special cabinet materials and strip styles. The top is equipped with a hanging beam, and the bottom is equipped with a bottom beam. The hanging beam is used to lift the screen. Between the row and the row of boxes, it is connected with a hoisting mechanism, and the horizontal box is tightened with a lock. Hoisting mechanism is divided into: gear type, taper rod type, bolt type. The gear type is more expensive and beautiful, and the taper rod type is affordable and reliable. The bolt type is the cheapest, reliable, more troublesome to assemble, and suitable for the case of repeated disassembly and assembly.

 

 

Arc and special-shaped installation methods:

Helilai will also tailor the installation method of curved and special-shaped outdoor LED display for customers, screen length x width (height): LxW; Picture length W: refers to the height of the picture; Picture length L: The length of the picture. The length of the picture can be preliminarily determined by the circumference of a circle or arc. Divide by the module length to determine the number of modules. For the round screen, try to divide it into 92 modules; Try to determine the number of modules in a row according to the integer digit multiples of 2, 3, 4, 5, and 6 (convenient to divide the box and easy to produce). The draft slope of a module is generally 2 degrees, and a module is only 4 degrees. That is, 92 modules are generally needed to form a perfect circular screen. It should not be less than 60 modules. Once you have determined the number of modules in a row, you can get the length of the screen. Screen length L = number of modules * module length; Picture area A=L*W; For non-circular screens (curved screens), they only need to be divided according to their needs, just like cutting a cake. The mounting bracket needs to be customized according to the size of the round screen (curved screen).

 

 

What do you need to pay attention to when installing outdoor LED displays?

 

 

Steel structure

Usually the outdoor LED display installation area is larger, and most of them are installed in densely populated places, and the design of its steel structure should consider many factors such as foundation, wind load, waterproof, dustproof, moisture-proof, ambient temperature, lightning protection, and surrounding population density. At the same time, auxiliary equipment such as power distribution cabinets, air conditioners, axial fans, and lighting also need to be placed in the steel structure, as well as maintenance facilities such as horse roads and ladders. Therefore, during the implementation, the entire outdoor screen steel structure should have the design drawings after passing the review of the competent government departments to ensure the reliability and safety of the entire steel structure.

 

 

Waterproof and moisture-proof

Outdoor LED display is installed outdoors, often exposed to the sun and rain, wind blowing dust cover, poor working environment, electronic equipment is wet or seriously damp will cause short circuit or even fire, causing failure and even fire, resulting in losses; Therefore, the screen body and the joint part of the screen body and the building must be strictly waterproof and leak-proof; The screen body should have good drainage measures, and once the water accumulates, it can be discharged smoothly; Pay attention to waterproof and moisture-proof.

 

Ventilation and heat dissipation

Outdoor LED display should be installed with ventilation equipment to cool down, so that the internal temperature of the screen is -10°C~40°C. An axial fan is installed above the back of the screen to discharge heat; If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned, so that the LED display system can not work normally.

 

Lightning protection grounding

The integration of electronic components in outdoor LED displays is high, and their sensitivity to anti-interference is getting higher and higher. Lightning can compromise a display system in a variety of ways, and in general, it can hit the screen directly and then release it to the ground through a grounding device. Cause mechanical, electrical, and thermal damage where lightning currents pass. The solution is equipotential connection, that is, the ungrounded or not well grounded metal shell, the metal skin of the cable, and the metal frame in the display screen are reliably welded and connected with the grounding device, so as to prevent the overvoltage counterattack on the internal insulation and cable core of the equipment due to the transmission of the high potential of lightning into the ground on these objects due to the induction high voltage or the grounding device. Outdoor LED display will also be attacked by strong electricity and strong magnetism caused by lightning, in order to make the large current caused by lightning can be discharged in time, reduce the overvoltage on the equipment, and limit the lightning intrusion wave. Lightning protection devices should generally be installed on display screens and buildings.
