Outdoor LED display installation requirements and precautions
What are the requirements and precautions for outdoor LED display installation? Outdoor led display is one of the main products for publicity. It has been favored by many people in the media industry. Today led display small series for everyone to introduce their installation should pay attention to matters.
1. Install lightning protection devices on electronic advertising screens and buildings. The main body of the display screen and the casing are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by the lightning discharges in time; the display screen may be subject to strong magnetic and magnetic attack caused by lightning.
2. The screen body and the joint between the screen body and the building must be strictly waterproof and leakproof; the screen body must have good drainage measures, and once discharged, the water can be smoothly discharged; pay attention to waterproof and moisture-proof. The display screen is installed outdoors, often exposed to the sun and rain, and the working environment is harsh. If the electronic device is wetted or severely dampened, it will cause a short circuit or even a fire, causing a malfunction or even a fire, resulting in loss;
3. Select the industrial-grade integrated circuit chip whose working temperature is between -40°C and 80°C to prevent the LED electronic advertising screen from starting when the winter temperature is too low.
4. Install the ventilation equipment to reduce the temperature, so that the internal temperature of the screen is between -10 °C ~ 40 °C. Axial fans are installed behind the screen body to discharge 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 making the display system can not work normally;
5. In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness light-emitting diodes must be used; increasing contrast, wide audience, wide line-of-sight requirements, and wide field of vision requirements; large changes in ambient light, especially sunlight Direct.
6. The display medium adopts a new wide viewing angle tube, wide viewing angle, pure color, consistent coordination, and the life of more than 100,000 hours. The outer package of the display medium is a popular covered square tube, silicone seal, and no metal assembly; Exquisite appearance, durable, with direct sunlight, dust, waterproof, high temperature, anti-circuit short circuit
