Outdoor LED display safe operation has to be considered and dealt with

The outdoor led display faces the following problems before installation and use. The led display must handle these problems in order to operate safely.

First, the led display is installed outdoors, often exposed to the sun and rain, and the working environment is bad. If the electronic equipment is wet or seriously damp, it may cause a short circuit or even a fire, causing malfunction or even fire, resulting in loss.

Second, the led display may be subject to strong electric and magnetic attacks caused by lightning.

Third, the ambient temperature changes greatly. When the outdoor led display is working, it must 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, so that the display system cannot work normally.

Fourth, the outdoor led display, the audience is wide, the line of sight requirements are far, the field of vision is wide; the ambient light changes greatly, especially the direct sunlight.

The above is the special requirements of outdoor led display. For these characteristics, the following small series gives you a summary of the precautions for outdoor led display.

1. The screen body of the LED display screen and the joint between the screen body and the building must be strictly waterproof and leakproof; the screen body should have good drainage measures, and once the water accumulation occurs, it can be discharged smoothly.

Second, install lightning protection devices on led displays and buildings. The main body and the outer casing of the display are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning is discharged in time.

Third, install ventilation equipment to cool down, so that the internal temperature of the outdoor led display is between -10 °C ~ 40 °C. An axial fan is installed on the back of the screen to dissipate heat.

Fourth, select the industrial grade integrated circuit chip with working temperature between -40 ° C ~ 80 ° C, to prevent the winter temperature is too low to make the led display can not start.

5. In order to ensure long-distance visibility under strong ambient light conditions, outdoor LED displays must use ultra-high brightness LEDs.

Sixth, the display medium of the led display screen adopts a new wide viewing angle tube, the viewing angle is wide, the color is pure, the coordination is consistent, and the service life exceeds 100,000 hours. The outer packaging of the display medium is currently popular with the square-shaped cylinder with a cover, silicone seal, no metallization assembly; its appearance is exquisite and beautiful, durable, with direct sunlight, dustproof, waterproof, high temperature, anti-circuit short circuit "Five defenses" features.
