With the development of society, the market scale of LED display in China is growing. According to the different use and use environment, LED display can be divided into indoor use and outdoor use. Compared with indoor LED display, outdoor LED display should take more protective measures. So the next small series for you to introduce outdoor LED display need to do what protective measures.
1. Waterproof, dustproof and moistureproof measures for the whole screen
Seamless connection shall be made between the box and the box, and between the screen and the stressed installation object, so as to avoid water leakage and dampness. Good drainage and ventilation measures should be taken in the interior of the screen. If there is water in the interior, it can be treated in time.
2. Ventilation measures should be taken inside the screen
A certain amount of heat will be generated when the screen is powered on. If the heat is not discharged and accumulated to a certain extent, the internal environment temperature will be too high, which will affect the work of the integrated circuit. If it is serious, it can lead to burnout, so that the display can not work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen, and keep the temperature of the internal environment between minus 10 ℃ and 40 ℃.
3. Lightning protection measures for installation buildings and screens
In order to make the display screen avoid the strong electromagnetic attack caused by lightning, the screen body and the outer packaging protective layer of the display screen must be kept grounded, and the resistance of the grounding line should be less than 3 Ω, so that the current caused by lightning can be discharged from the ground in time.
