Because the LED display industry does not use the environment, its installation method is also different. In general, the installation methods of indoor LED display screens are generally: mosaic installation, wall-mounted installation, wall-mounted installation, etc .; outdoor LED display screens are more commonly used in column-type installation and roof-type installation. The following editor makes a detailed description of the installation method of LED display manufacturers:
However, due to the particularity of its products, LED display screens often reflect the quality of the product and determine the effect of the display screen in use. Therefore, the installation and debugging of LED display screens is a very important technical activity. Here, the editor has compiled and compiled six common installation methods in the LED display industry:
What are the common installation methods of LED display? List of common installation methods
1. Mosaic installation: indoors, suitable for indoor screens with small area. Due to the small installation space, in order not to take up space, according to the size of the screen body, dig an area of ​​the same size on the wall, and embed the LED display in the wall. The wall is required to be a solid wall. The cost of pre-maintenance is higher. For outdoor installation, the mounting structure is suitable for the display project that has been included in the planning and design of the building. The construction space for the display screen is reserved in advance during the construction of the civil works project. It is embedded in the wall of the building, leaving enough maintenance space on the back.
2. Wall-mounted installation: It is mostly suitable for indoor LED display installation, with a small area (less than 10 square meters). The wall requirements are solid walls, hollow bricks or simple partition walls are not suitable for this installation method.
3. Hanging installation: It is mostly suitable for large-scale places such as station LED electronic display, airport LED electronic display, etc. to play the role of indicating signage. The screen area is required to be small. (Below 10 square meters) It is required to have a suitable installation site, such as a beam or lintel above, and the screen body should be added with a back cover under normal circumstances.
Ordinary mounting is suitable for single-box display screens with a total weight of less than 50kg. It can be directly hung on the load-bearing wall without the need to reserve maintenance space. The display box adopts a front maintenance design, and the display screen is lifted from the bottom during maintenance That's it.
The rack mount is suitable for general outdoor display screens. Considering the difficulty of display screen maintenance, steel structure is used for support between the screen body and the wall. 800mm maintenance space is reserved. The space is equipped with maintenance facilities such as horse tracks and climbing ladders. And install auxiliary equipment such as power distribution cabinet, air conditioner, axial fan, lighting,
4. Column-type installation: It is mostly used for the installation of outdoor advertising LED electronic display screens. It has wide field of vision and relatively empty places around it, such as squares and parking lots. According to the size of the screen body, it can be divided into single-post and double-post installation. The column installation is suitable for the installation of LED display screens on open ground, and the outdoor screen is installed on the upright column. In addition to the steel structure of the screen body, the column type also needs to be made of concrete or steel columns, mainly considering the geological conditions of the foundation.
5. Rooftop installation: It is mainly suitable for outdoor advertising LED electronic display. The installation site is mainly the roof of the building. As the height of the building increases, the windproof level to be considered must also increase.
6. The seat mounting structure is to use a concrete structure on the ground to build a wall that is sufficient to support the entire LED display. Construct a steel structure on the wall to install the display. The steel structure reserves 800mm of maintenance space and places related equipment and maintenance facilities. .
Precautions for installing outdoor LED display
The outdoor LED display has a large area, and the design of its steel structure should consider many factors such as foundation, wind load, earthquake level, waterproof, dustproof, ambient temperature, and lightning protection. Auxiliary equipment such as power distribution cabinets, air conditioners, axial fans, and lighting should be placed in the steel structure, as well as maintenance facilities such as horse tracks and ladders. The whole outdoor screen structure should meet the protection grade below IP65. In general, the considerations for installing outdoor LED display installation are:
(1) The display screen is installed outdoors, often exposed to the sun, rain, wind and dust cover, and the working environment is harsh. Wetted or severely dampened electronic equipment can cause short circuits or even fires, which can cause malfunctions or even fires, causing losses.
(2) The display screen may be attacked by strong electricity and magnetism caused by lightning.
(3) The ambient temperature varies greatly. The display itself generates a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burnt, thereby making the display system unable to work properly.
(4) The audience has a wide area, long sight distance and wide field of vision; the ambient light changes greatly, especially it may be exposed to direct sunlight.
In response to the above special requirements, the installation of outdoor display screens must:
(1) The screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, and it can be smoothly discharged once the accumulated water occurs.
(2) Install lightning protection devices on the display screen and buildings. The main body of the display and the housing are kept well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning is discharged in time.
(3) Install ventilation equipment to lower the temperature so that the internal temperature of the screen is between -10 ℃ and 40 ℃. An axial fan is installed above and behind the screen body to discharge heat.
(4) Use industrial-grade integrated circuit chips with operating temperatures between -40 ° C and 80 ° C to prevent the display temperature from starting too low in winter.
(5) It has the characteristics of "five protections" against direct sunlight, dust, water, high temperature and short circuit.
