Outdoor LED advertising screen winter installation precautions

For outdoor LED displays, due to the special use environment outdoors, it must be treated differently from ordinary indoor LED displays during installation. Especially in the cold winter season, factors such as low temperature, rain and snow are also very easy to affect the installation of LED outdoor display.

Six precautions for outdoor LED display installation:

1. Install lightning protection devices on display screens and buildings

The main body and shell of the display screen 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; the display screen may be attacked by strong electric and magnetic fields caused by lightning.

2. Waterproof measures for 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 severe dampness of electronic equipment will cause short circuit or even fire, causing failure or even fire, resulting in losses;

3. Circuit chip selection

Select 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 keep the internal temperature of the screen between -10℃~40℃

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 be normal work;

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 light-emitting diodes must be selected; the contrast ratio is increased. The audience is wide, the sight 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, life span of more than 100,000 hours. Direct sunlight, dustproof, waterproof, anti-high temperature, anti-circuit short-circuit five-proof features.

The cold winter season brings certain difficulties to the installation of outdoor LED electronic display screens. The six major matters in the installation process involve the future use and safety of the product, and must be treated strictly and seriously.
