Introduction
LED display screens not only beautify urban buildings, but also become the new favorite of information dissemination. However, to ensure its safety and effect on buildings, several core elements need to be considered. This article will briefly introduce these key points.
1. Evaluation of the installation site and structural support of LED display screens
1). Site evaluation
- Dimension evaluation
You need to use high-precision measurement tools (such as laser rangefinders, total stations, etc.) to accurately measure the length, width, and height of the installation site to ensure that it fully matches the specifications of the LED display screen.
This step must be accurate. If errors are made, the final customized LED display screen will not be suitable for the on-site size, and the installation will be ugly.
Based on the measurement results, draw a detailed layout diagram, including the location of the display screen, installation frame, maintenance channel, audience viewing area, etc., to ensure that the overall layout is reasonable and meets the use requirements.
- Bearing capacity evaluation
Check the site structure drawings, geological survey reports, and other relevant materials to understand the site’s bearing capacity, foundation bearing capacity, and other key information.
You need to perform detailed load calculations based on the weight of the LED display (including the display itself, installation frame, connecting cables, heat dissipation equipment, etc.) and possible additional loads (such as the weight of personnel and equipment during maintenance).
At the same time, consider the impact of dynamic loads (such as wind loads, seismic forces, etc.) on the structure. Add the calculated total load to the safety margin and compare it with the bearing capacity of the site to ensure that it is within the safe range.
2). Structural support assessment
- Stability assessment
Since it is installed on the facade of the building, there may be a falling accident if you are not careful, so you must conduct a detailed inspection of the supporting structure, including welding points, bolt connections, and the integrity of supporting components to ensure that the structure is stable and defect-free.
Professional vibration testing equipment and structural analysis software are used to perform vibration testing and stability analysis on the supporting structure to evaluate its stability and safety under external forces such as wind loads and earthquakes.
- Wind load assessment
Check local meteorological data to understand possible parameters such as wind speed, wind direction, wind pressure, and wind load conditions under extreme weather conditions. This is also very important. All building designs have wind load assessments and predictions, and the LED display screen installed in the building is no exception.
You need to use the principles and methods of wind engineering to calculate the wind pressure on the display screen based on meteorological data and the size, shape, and other parameters of the display screen.
Then, based on the wind pressure calculation results, the support structure is reinforced by adding support components, using stronger materials, optimizing the structural layout, etc., to ensure that the support structure can withstand the wind load.
2. Evaluation of the environmental adaptability of the purchased LED display screen
1). Waterproof and dustproof treatment
LED displays, especially those used outdoors, often face challenges from environmental factors such as rain and dust. Waterproof and dustproof treatment can not only protect the electronic components inside the display screen from damage but also extend the service life of the display screen.
1.1). Evaluation points:
Waterproof level: Evaluate the waterproof ability of the display screen according to the IP (Ingress Protection) protection level standard. Outdoor displays are usually required to reach IP65 or higher waterproof levels to ensure that they can still work normally in severe weather such as heavy rain.
Dustproof design: Also evaluate the dustproof ability of the display screen according to the IP protection level standard. The higher the dustproof level, the less likely it is for dust to accumulate inside the display, thereby reducing the risk of failure caused by dust.
Installation measures: During the installation process, additional waterproof and dustproof measures should be taken, such as using waterproof seals, dustproof nets, etc., to ensure the sealing between the display and the external environment.
1.2). Recommendations:
Before purchasing, learn in detail about the waterproof and dustproof level and specific design of the display to ensure that it meets the requirements of the use environment.
During the installation process, strictly follow the manufacturer’s guidelines to ensure that all waterproof and dustproof measures are properly implemented.
2). Power supply
The power supply is the basis for the stable operation of LED display screens. An unstable power supply may cause the display screen to flicker, cause a black screen, or even cause damage.
This is especially important for LED display screens installed on the facade of the building. Once the power supply is insufficient or there is a problem, maintenance is also very troublesome.
2.1). Evaluation points:
Power consumption requirements: Understand the power consumption requirements of the display screen, including maximum power, average power, etc., to ensure that the power supply can meet the operation requirements of the display screen.
Power connection: Have a professional electrician perform the power connection to ensure that the connection is firm and safe. At the same time, consider using appropriate cables and sockets to reduce power loss and safety hazards.
- Backup power supply: For outdoor or critical area displays, consider equipping with a backup power supply (such as UPS or generator) to cope with sudden power outages.
2.2). Recommendation:
Before purchasing, communicate with the manufacturer to understand the power requirements of the display, and consult professional electricians to ensure that the power supply plan is reasonable and feasible.
Check the power connection and cable status regularly to promptly detect and deal with potential safety hazards.
For displays equipped with backup power supply, regular maintenance and testing should be carried out to ensure that the backup power supply can work properly when needed.
3. Types and selection of high-rise LED display screens
1). Types of LED display screens
These large LED display screens are designed for outdoor environments and have extremely high brightness, ensuring that they are still clearly visible on sunny days.
They are usually composed of multiple LED single lamps, each of which is like a small glowing gem encapsulated in a spotlight cup to increase brightness.
These large screens are usually composed of multiple pixel units to form a dot matrix display effect. They are designed with protection characteristics to ensure stable operation in outdoor environments.
- LED grille screen (transparent LED screen):
This display is like a piece of transparent glass, but it can display various images and texts.
It has high transparency and will not block the view, so it is very suitable for installation on the exterior wall of high-rise buildings.
Unlike other transparent LED displays, grille LED displays are most suitable for outdoor installation because they have protective properties that other transparent screens do not have.
In addition, the installation methods of LED grille screens are flexible and diverse and can be customized according to the characteristics and needs of the building.
2). Choice of installation method
When we want to install LED displays on the exterior walls of high-rise buildings, we need to consider a variety of installation methods to ensure that the display is both stable and beautiful.
- Wall-mounted installation:
Although wall-mounted installation is simple and direct when used on the exterior walls of high-rise buildings, special attention should be paid to environmental factors such as the wall’s load-bearing capacity and wind pressure. If the wall is not strong enough or the wind pressure is too high, the display may fall off or be damaged.
- Hoisting installation:
For large and heavy displays, hoisting installation is a good choice. It can hang the display steadily in the air through a hoisting mechanism. But it should be noted that the hoisting mechanism must be very stable to ensure that the display will not shake when the wind is strong.
- Embedded installation:
Embedded installation is to embed the display screen completely into the wall so that it blends into the wall. This method can make the display screen look neater and more beautiful.
However, it should be noted that embedded installation has high requirements on the load-bearing capacity and construction accuracy of the wall, and it is necessary to ensure that the size of the display screen matches the hole in the wall completely.
- Customized installation:
In addition to the above common installation methods, customized installation design can also be carried out according to the actual situation of the high-rise building.
For example, the shape and size of the display screen can be designed according to the outline and shape of the building, or the most suitable installation method can be selected according to the characteristics of the building.
When choosing the installation method, we also need to consider the maintenance needs of the display screen. Because once the display screen on the exterior wall of the high-rise building is installed, it is difficult to perform frequent maintenance.
Therefore, when choosing the installation method, it is necessary to ensure that the maintenance of the display screen is convenient and quick so that it can be repaired and replaced in time when needed.
