What are the requirements and precautions for outdoor LED display installation?

 1. Install lightning protection devices on led electronic advertising screens and buildings. The main body and the shell of the display screen are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by thunder and lightning can be discharged in time; the display screen may be attacked by strong electricity and strong magnetism caused by thunder and lightning.

 2. 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, once accumulated water occurs, it can be discharged smoothly; pay attention to waterproof and moisture-proof. The display screen is installed outdoors, often exposed to the sun and rain, wind and dust cover, and the working environment is harsh. Electronic equipment being wet or severely damp can cause short circuit or even fire, cause failure or even fire, and cause loss;

3. Use industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the low temperature in winter from causing the LED electronic advertising screen to fail to start.

 

4. Install ventilation equipment to cool down so that the internal temperature of the screen is between -10°C and 40°C. An axial fan is installed on the top of the back of the screen to dissipate heat; when the LED electronic display is working, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, thus causing the display system unable to work properly;

5. In order to ensure long-distance visibility under strong ambient light, ultra-high brightness LEDs must be used; increase the contrast. The audience is wide, the viewing distance is required, and the field of view is wide; the ambient light changes greatly, especially if it is exposed to sunlight Direct shot.

 

6. The display medium adopts a new wide-view tube with wide viewing angle, pure color, consistent coordination, and a life span of more than 100,000 hours. The outer package of the display medium is currently the most popular rectangular tube with a cover, silicone seal, and no metalization assembly; its The appearance is exquisite and beautiful, sturdy and durable, and has the characteristics of anti-direct sunlight, dust-proof, waterproof, high-temperature resistance, and anti-circuit short circuit.
