Large-scale outdoor LED displays have become more and more popular. We can see those digital billboards in different cities and major streets. At the same time, the outdoor screen area is generally relatively large, mostly more than 50 square meters, and even hundreds of thousands of square meters.
Outdoor led display installation 5 tips
- Install lightning protection devices on led display screens and buildings
It is very necessary to do lightning protection for giant outdoor LED billboards. The LED main body and shell should have good grounding measures, and the grounding resistance should be less than 3 ohms. Large outdoor LED billboards will also be attacked by strong electricity and strong magnetism caused by lightning. In order to discharge the large current caused by lightning in time, reduce the overvoltage on the equipment and limit the intrusion wave of lightning. Generally, lightning protection devices should be installed on led display screens and buildings.
2. Pay high attention to waterproof and moisture-proof
The large outdoor LED digital signage is facing harsh working environment, often exposed to the sun and rain, wind blowing dust cover. The electronic equipment is wet or severely damp will cause short circuit or even fire, causing failure or even fire, resulting in losses. Therefore, the screen body and The junction of the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, so that the water can be discharged smoothly in the event of water accumulation; pay attention to waterproof and moisture-proof. It is worth noting that the protection level (front/back) of the outdoor LED display is at least IP65/IP54, which cannot be lower than this protection level.
3. Circuit chip selection
Select industrial-grade integrated circuit chips whose working temperature is between -40°C and 80°C to prevent the display screen from being unable to start due to the low temperature in winter.
4. Install ventilation equipment to cool down
Install ventilation equipment to cool down, so that the internal temperature of the screen is between -10 ℃ ~ 40 ℃. An axial flow fan is installed on the back of the screen to discharge heat; the display screen itself will generate 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 burned, so that the display system cannot work normally. Work;
5. Install the steel structure
As the steel frame structure carrying the huge outdoor LED display, its firmness should be ensured to achieve the effect of wind resistance and earthquake resistance. Usually outdoor LED displays have a large installation area, and most of them are installed in densely populated places. The design of the steel structure should consider the foundation, wind load, waterproof, dustproof, moistureproof, ambient temperature, lightning protection, surrounding population density, etc. factor. At the same time, auxiliary equipment such as power distribution cabinets, air conditioners, axial fans, and lighting need to be placed in the steel structure, as well as maintenance facilities such as horse tracks and ladders. Therefore, during implementation, the entire outdoor screen steel structure should have design drawings that have passed the review of the competent government department to ensure the reliability and safety of the entire steel structure.
