Outdoor LED billboard installation need to pay attention to what?
LED industry people know that to outdoor LED billboards with good, installation and commissioning links are essential, then for technical construction personnel, know good outdoor construction, maintenance of advertising screen skills will be able to better promote the business advertising, information dissemination, but also as a technical construction personnel must be familiar with, in fact, outdoor LED billboards are roughly divided into four parts of the installation in general: field Survey, equipment construction, product installation, product commissioning.
For these outdoor LED billboards to build, to distinguish between outdoor wall advertising screen and hanging advertising screen. The actual installation of these screens, we should be based on the distance height, with cranes and winches for segmented lifting, while ensuring that the staff below and above cooperate with each other, in order to make the high altitude of the LED screen has a better installation and use of the process. We are in the process of building, safety and refinement of the operation must meet the first requirements.
Usually the main support structure of the outdoor LED billboard is usually based on steel materials, because in the open-air environment, by the temperature, humidity, harmful substances and other factors, it is extremely easy to be oxidized and caused by corrosion, and even serious corrosion can make the steel components resistance to load capacity is greatly reduced, then we need to pay attention to what aspects of the time of installation?
Steel Structure
Usually outdoor LED billboard installation area is large, and most of them are installed in more intensive places, the design of the steel structure should consider the foundation, wind load, waterproof, dustproof, moisture, ambient temperature, lightning, surrounding population density and many other factors. At the same time, the steel structure also needs to be placed in the distribution cabinet, air conditioning, axial fans, lighting and other auxiliary equipment, but also have a horse path, ladder and other maintenance facilities.
Waterproof and moisture-proof
Outdoor LED billboard installed in the outdoor, often sun and rain, wind and dust cover, the working environment is harsh, electronic equipment is wet or serious moisture will cause short circuit or even fire, triggering failure or even fire, resulting in losses; so the screen body and the combination of the screen body and the building must be strictly waterproof leakage prevention; the screen body should be a good drainage measures, once the occurrence of water can be discharged smoothly; pay attention to waterproof, moistureproof.
Ventilation and heat dissipation
Outdoor LED billboards should be installed with ventilation equipment to cool down the temperature, so that the internal temperature of the screen body at -10 ℃ ~ 40 ℃. The screen body behind the top of the installation of axial fans to discharge heat; outdoor LED billboard work itself to produce a certain amount of heat, if the ambient temperature is too high and poor heat dissipation, the integrated circuit may not work properly, or even burned, so that the LED display system can not work properly.
Lightning grounding
Outdoor LED billboard in the electronic components of high integration, its sensitivity to anti-interference requirements are also increasingly high. Lightning can jeopardize the display system in various ways, in general, it may directly hit the screen body and then drain into the ground through the grounding device.
In the lightning current through the place caused by mechanical, electrical and thermal damage. The solution is equipotential connection, that is not grounded or not well grounded metal casing, the metal skin of the cable, the display of the metal frame and the grounding device reliable welding connection, to prevent these objects due to the induction of high voltage or grounding device on the lightning into the ground of the transmission of high potential caused by the internal insulation of the equipment, the cable core of the over-voltage counterattack.
Outdoor LED billboards will also be caused by lightning strong electric and magnetic attacks, in order to make the lightning caused by large currents can be discharged in a timely manner to reduce the overvoltage in the equipment, to limit the lightning intrusion wave. Usually should be installed in the display and buildings on the lightning device.
Outdoor LED billboard with good, installation and commissioning links are essential, outdoor LED billboard installation technicians to speak, must know the structure of outdoor LED billboard construction, maintenance screen skills will strongly promote the business advertising, information dissemination, but also technical construction personnel must be familiar with, specifically, the outdoor billboard LED electronic display installation there are four links: field survey, Equipment construction, installation, commissioning and use.
Field survey according to the actual situation
Outdoor LED billboards before installation, should be for the specific environment, terrain, topography, light-emitting radiation range, brightness acceptance and other parameters Jinxin unified test, in order to ensure the smooth installation of billboards, the requirements of lifting before installation, must be for the commanding officer to carry out the implementation of a unified lifting program to ensure that can be normal, stable use of the equipment. Different situations are treated differently, so as to take a more appropriate way.
LED equipment construction
For some outdoor LED billboard construction, to distinguish between wall advertising screen, hanging advertising screen and roof advertising screen. The actual installation, should be based on the distance height, with cranes and winches for segmented lifting, while ensuring that the personnel above each other, for the high altitude LED advertising screen, there is a better installation and use of the process. Building process, safety and refinement of the operation is the first requirement.
Light-emitting radiation range debugging
Due to the different radiation range, LED display building perspective is not the same, according to the field acceptance ability and the usual range of perspective for outdoor LED billboard fixed installation work, to ensure that every angle from afar, can see normal, brightness balanced image, subtitle information, large perspective and appropriate brightness with, in order to maximize the benefits.
Follow-up inspection and maintenance
Follow-up testing, including a wide range, such as LED display waterproof, heat dissipation layer, LED indicates waterproof coating, display above the range of rain, both sides of the heat dissipation empty, power supply line, etc. These basic parts and components of the product constitutes the entire stability of the good graphic LED display. Of course, the later technical maintenance is also very important, we should be unified management and maintenance of these parts, encounter product rust, instability, damage, need to be replaced in a timely manner, to ensure the safe use of the entire display.
