Six ideas for outdoor LED display installation
1. Install lightning protection devices on LED displays and buildings.
The main body and shell of the LED display screen are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning can be discharged in time; the display screen may be attacked by strong electricity and strong magnetic fields caused by lightning.
2. Waterproof measures for the LED display itself
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. The display screen is installed outdoors, often exposed to the sun and rain, and the wind blows the dust cover, and the working environment is harsh. Wetting or serious damping of electronic equipment will cause short circuit or even fire, causing failure or even fire, resulting in losses;
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, 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 be normal. Work;
5. Must choose ultra-bright light-emitting diode
In order to ensure long-distance visibility in the case of strong ambient light, ultra-high brightness light-emitting diodes must be selected; the contrast ratio is increased. The audience is wide, the viewing distance is required to be far, and the visual field is required to be wide; the ambient light changes greatly, especially it may be exposed to direct sunlight.
6. The display medium uses a new type of wide viewing angle tube
Wide viewing angle, pure color, consistent coordination, lifespan of more than 100,000 hours. The outer package of the display medium is currently the most popular square cylinder with a cover, silicone seal, and no metallized assembly; its appearance is exquisite and beautiful, sturdy and durable, with anti- Direct sunlight, dustproof, waterproof, anti-high temperature, anti-circuit short-circuit five-proof features.
The installation precautions of outdoor LED electronic display involve the future use and safety of the product, and must be treated strictly and seriously.
