Six precautions for outdoor LED display installation
Six precautions for outdoor LED display installation: lightning protection, waterproof, ventilation, brightness, chip, and angle. If you do these points, the LED display can get a better and longer service life and viewing experience.
1.Install lightning protection devices on display screens and buildings.
The main body of the display screen and the shell should be 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 electric and strong magnetic caused by lightning.
2. pay attention to waterproof
Waterproof measures of 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 can cause short circuit or even fire, causing failure or even fire, resulting in losses.
3.Circuit chip selection
Use industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the display 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°C and 40°C. 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. .
5.Ultra-high brightness light-emitting diodes must be selected
In order to ensure long-distance visibility in the case of strong ambient light, ultra-high-brightness LEDs 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 adopts a new type of wide viewing angle tube.
Wide viewing angle, pure color, consistent coordination, and life expectancy of more than 100,000 hours. Direct sunlight, dustproof, waterproof, high temperature resistance, circuit short circuit prevention
