What should I pay attention to when restarting the installation of the LED advertising screen?

2022-03-11


 For LED advertising screens, because they are used outdoors. Therefore, it must be treated differently from ordinary indoor LED advertising screens. The installation requirements of LED advertising screens are also different from ordinary indoor LEDs. The installation must be done in detail. Otherwise it is very likely to cause trouble. What should I pay attention to when restarting the installation of the LED advertising screen?

  Six major requirements for the installation of LED advertising screens

 1. Install lightning protection devices on LED advertising screens and buildings.

 The main body and shell of the LED advertising 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. Waterproof measures of the LED advertising screen itself

 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. Circuit chip selection

  Use industrial-grade integrated circuit chips with a working temperature between -40°C and 80°C to prevent the display from starting up when the temperature is too low in winter.

 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; the LED advertising 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, making the display system unable to normal work;

 5. Must choose ultra-high brightness light-emitting diodes

 In order to ensure long-distance visibility under strong ambient light, ultra-high brightness light-emitting diodes 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 directly exposed to sunlight.
