Outdoor LED displays are faced with the following problems before they are installed and used. These problems must be dealt with in order to operate safely.
1. The LED display is installed outdoors, often exposed to the sun, rain, wind and dust, and the working environment is harsh. Electronic equipment getting wet or severely damp can cause short circuit or even fire, cause malfunction or even fire
, Causing losses.
2. The LED display screen may be attacked by strong electricity and magnetism caused by lightning.
3. The environment temperature changes greatly. When the outdoor LED 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
Was burned, so that the display system can not work properly.
Fourth, the outdoor LED display has a wide audience, a long viewing distance, and a wide field of view; the ambient light changes greatly, especially if it is exposed to direct sunlight.
The above are the special requirements of outdoor LED displays. In view of these characteristics, the following editor summarizes the points for attention of outdoor LED displays.
1. The screen body of the LED display screen 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, and once the accumulation of water occurs, it can be discharged smoothly.
2. Install lightning protection devices on LED displays and buildings. The main body of the display screen and the shell 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.
3. Install ventilation equipment to cool down so that the internal temperature of the outdoor led display is between -10°C and 40°C. An axial flow fan is installed on the top of the back of the screen to dissipate heat.
4. 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 display to fail to start.
5. In order to ensure long-distance visibility under strong ambient light conditions, outdoor LED displays must use ultra-high-brightness light-emitting diodes.
Sixth, the display medium of the LED display uses a new type of wide viewing angle tube, which has a wide viewing angle, pure color, consistent coordination, and a life span of more than 100,000 hours. The outer packaging of the display medium is currently the most popular rectangular tube with a cover, sealed with silicone and no metalized assembly; its appearance is exquisite and beautiful, sturdy and durable, and has protection from direct sunlight, dust, water, high temperature, and circuit short circuit. "Five defenses" features.
