In summer, along with long rainy seasons such as thunderstorms, and typhoons in summer have a great impact on coastal cities, large areas of rain put forward higher protection requirements for LED displays to prevent lightning strikes and rain.


1. Outdoor led display is wind-resistant and shock-resistant


With the increasing application of outdoor LED display advertising, the installation forms of LED display are also becoming more and more diverse, including wall hanging, inlay, ceiling, roof, pillar, etc. In order to prevent the LED display equipment from falling, there are strict requirements on the wind load and seismic performance and the selection of load-bearing steel structure steel, especially the requirements for roof installation and installation columns are stricter than other forms.


2. Lightning protection measures for outdoor led large screen


In order to ensure good grounding, all metal boxes and back covers of led display equipment have independent grounding terminals, which are waterproof fasteners and grounded with ratchet gaskets. The commonly used ground wire structure for large-screen equipment is three grounds (equipment working grounding, power supply grounding, and lightning protection grounding) to protect the power supply and signal system from lightning strikes and impulse voltage damage to the equipment.


3. Outdoor led large screen anti-leakage inside and outside


The mask and box are made of insulating material. The resistance of the insulating material is greater than 10 megohms, and the leakage current is less than 1.8MA. After inspection by the headquarters, the product can still withstand 50hz under high temperature and high temperature. The dielectric breakdown of the test voltage requires 1500W for 1 minute. The circuit board will be protected by three anti-paint, and the quality of large led screen in the world should be higher than IP65. So as to ensure leakage and waterproof performance.

4. Control the humidity of the outdoor large screen


When the moisture full-color screen is powered on, it will cause the LED display components to corrode and cause damage; therefore, to maintain the full-color LED environment of the large screen, do not let any objects with humidity characteristics enter the large LED screen.


5. Active protection of outdoor led display


To prevent possible problems, take active protective measures and try to remove the large-screen LED screen; when cleaning the screen, try to wipe it lightly to reduce the possibility of damaging the LED display.


6. Outdoor led display screen controls screen current


When playing, do not stay on the all-white, red, green, blue and other bright screens for a long time, so as to avoid excessive current, overheating of the power cord, damage to the LED lights, and affect the service life of the LED display. Do not disassemble or splicing the screen at will.


7. Use LED display outside the control room


It is recommended that the led display screen rest for more than 2 hours a day, and at least once a week in the rainy season. Usually, the screen is turned on at least once a month for more than 2 hours.


8. Keep the power supply of outdoor led display stable


Maintain stable power supply, do a good job of grounding protection, and avoid lightning strikes, especially in harsh natural conditions, especially in thunderstorms.


9. It is forbidden to contact with conductive metals such as water and iron powder.


Put the LED display in a low-dust environment as much as possible. Larger dust will affect the display effect, and too much dust will damage the circuit. If water gets in for various reasons, please cut off the power immediately until the screen display is dry.


10. Outdoor led display is rainproof and waterproof


The led display is manufactured in a modular design, all composed of electronic components. Short circuit leakage can easily cause unnecessary losses. The LED display used outdoors must ensure that the equipment meets the relevant waterproof standard IP65 and above: module glue, back glue, waterproof box, waterproof rubber ring connected to the box.


Warm reminder, to buy outdoor LED display, it is recommended to choose a relatively strong manufacturer to place an order, such as a national-level professional, special and new little giant enterprise Lianchengfa and other manufacturers.
