In the spring, the south ushered in "back to the South", and then will enter the "rainy season", in this air can squeeze out the water season, if the pervasive water vapor stays in the LED display, it will cause dead lights, dark Problems such as short circuit, open circuit and lamp body damage, resulting in performance failure! Therefore, in order to ensure that the LED display can shine in the wet weather, we must do the spring moisture protection work.
LED module (unit board) moisture proof method
The first step of LED display moisture-proof is to ensure that the LED module has moisture-proof function. Let us look at the powerful giant color with good brand awareness and good reputation. How to do the LED module moisture-proof work.
The LED module needs to be dry and ventilated. When it is stored, it should be padded with pallets or other objects. It should not be in direct contact with the ground.
The installation environment is equipped with a temperature and humidity monitor. The ambient humidity is controlled below 60% RH, and the LED module is very comfortable.
When the sealed LED module (unit board) is stored, it needs to be repackaged and put into the appropriate desiccant.
If the LED module storage time exceeds 1 month, the module will be gradually increased in brightness for 6 hours before use: full brightness is set to 10%/1 hour, full brightness is set to 30%/1 hour, full brightness Set to 60%/2 hours, full brightness is set to 80%/1 hour, full brightness is set to 100%/1 hour. After 6 hours of aging, it can be used for the entire screen assembly.
Outdoor LED display moisture proof method
1, outdoor fixed display moisture-proof
The temperature and humidity monitor is arranged at the installation site of the outdoor LED display to monitor the humidity around the screen in time;
After the first rainy day or heavy rain after the installation of the screen body, it is necessary to check whether there is moisture, water droplets or moisture in the interior;
Under the ambient humidity of 10% to 85% RH, open at least once a day, each time the display works normally for more than 2 hours;
If the ambient humidity is higher than 90% RH or it is encountered in the south, the environment of the screen should be dehumidified and the display should work normally for more than 4 hours every day.
2, outdoor rental screen moisture
The outdoor rental LED display is in use. When it is raining, it must be powered off immediately. If it is too late to dismantle the screen, it should be covered quickly with a tarpaulin prepared in advance. When it is sunny, take the box out and dry it. If you are experiencing continuous rain, open the back cover of the cabinet and blow it dry with a fan. Then dry in a ventilated and dry room for more than 8 hours. Low brightness is guaranteed to illuminate for more than 4 hours, and the moisture in the electronic components is fully emitted.
Indoor LED display moisture-proof Dafa
1, indoor fixed display moisture-proof
In the ambient humidity of 10% to 65% RH, the display screen is opened at least once a day, each time ensuring normal operation for more than 4 hours;
If the ambient humidity is higher than 65% RH or it is encountered in the south, the environment of the screen should be dehumidified, and the display should be operated normally for more than 8 hours every day. The relevant doors and windows should be closed at night to prevent the screen from being damaged by nighttime resurgence. .
2, indoor rental screen moisture
After each use, it should be immediately loaded into the air transfer box for sealed storage;
Each air transfer box shall be provided with a desiccant or hygroscopic bag of not less than 50g; and the desiccant or hygroscopic bag shall be inspected regularly for failure, and shall be replaced every 2 months;
In the ambient humidity of 10% to 65% RH, the display should be taken out of the lighting work (play video) for more than 2 hours every half month;
If the ambient humidity exceeds 65% RH or encounters a southerly wind, the display should be taken out of the lighting work (play video) for more than 2 hours per week;
During the use of the screen body, the screen body should be protected from rain or water. If it is not very wet, the water should be dried and blown dry with a hair dryer. After the screen is placed for 2 hours, it will be lit for 2 hours. ;
It is strictly forbidden to use the indoor rental screen as an outdoor rental screen, especially in an open air environment;
In short, whether it is indoors or outdoors, the most effective way to avoid moisture damage to the display function is to use it frequently. The working display itself generates some heat and can evaporate some water vapor, which greatly reduces the short circuit caused by moisture. The possibility. Therefore, the frequently used display screen has a much smaller humidity effect than the less commonly used display.
