How to do the protective measures for the LED display? As a kind of outdoor advertising, LED display screens have far higher environmental requirements than ordinary display screens. During the use of outdoor LED displays, due to different environments, they are often affected by severe weather such as high temperatures, typhoons, rainstorms, and lightning. In order to make the display look safe and sound under severe weather, what precautions should we take?

One is high temperature resistance

  LED display screens generally have a large area, consume more power during use, and correspondingly heat dissipation. In addition, the external temperature is relatively high. If the heat dissipation problem cannot be solved in time, it is very likely to cause problems such as heat and short circuit of the circuit board. To ensure the good condition of the display board, use the hollow design as far as possible in the shell design, which is conducive to heat dissipation. During installation, keep good air permeability at the display screen according to the equipment condition, and add heat dissipation equipment to the display screen if necessary, such as adding an air conditioner or fan inside to help the display screen dissipate heat.

  The second is anti-typhoon

  The outdoor LED display has different installation positions and different installation methods, including wall-mounted, embedded, column, and suspended. Later in the typhoon season, in order to prevent the outdoor LED display screen from falling off, strict requirements were put forward on the load-bearing steel structure of the display screen. The construction unit must design and install in strict accordance with the anti-typhoon grade standard, and at the same time have a certain degree of earthquake resistance to ensure that the outdoor LED display will not fall off, causing casualties.

  The third is rainproof

  In the rainy places in the south, the LED display itself must have a high level of waterproof protection to avoid being corroded by rain. In the outdoor environment, the outdoor LED display should reach IP65 protection level, the module should be filled and sealed, and the waterproof box should be selected, and the module and the box should be connected with a waterproof ring.

  The fourth is lightning protection

  (1) Lightning protection: If the outdoor large LED screen is not within the protection range of nearby high-rise buildings, lightning rods should be installed on or near the top of the steel structure of the display;

  (2) Induction lightning protection: The power system of the outdoor LED display adopts 1-2 power lightning protection, the signal line adopts signal lightning protection device, the power system of the computer room adopts three-level lightning protection, and the signal enters and exits the computer room equipment terminal adopts signal lightning protection Device

  (3) All LED display circuits (power and signal) should be shielded and buried;

  (4) The front end of the outdoor LED display and the grounding system of the computer room should meet the system requirements. Generally speaking, the grounding resistance of the front end should be less than or equal to 4 ohms, and the grounding resistance of the equipment room should be less than or equal to 1 ohm.
