How to do the waterproof and heat dissipation measures for outdoor LED displays?

 

 

 

 

LED display products are becoming more and more abundant, and its application scenarios are becoming more and more extensive,What protective measures should be taken for outdoor LED displays?

 

1. Lightning protection measures for the installation of buildings and screens

In order to avoid the strong electromagnetic attack caused by lightning, the screen body and the outer packaging protective layer of the display screen must be grounded, and the resistance of the grounded line should be less than 3 ohms, so that the current caused by lightning can be discharged from the ground wire in time.

 

2. Waterproof, dustproof and moisture-proof measures for the entire screen

At the junction between the box and the box, as well as the combination of the screen and the stressed installation object, it is necessary to achieve seamless connection to avoid water leakage and moisture. The inside of the screen should have good drainage and ventilation measures, and if there is water accumulation inside, it can be dealt with in time.

 

3. On the selection of circuit chips

In some countries and regions, the temperature in winter can reach more than minus 30 degrees, so when choosing a circuit chip, it is necessary to choose an industrial-grade chip with a working temperature of minus 40 degrees Celsius and 80 degrees Celsius, so as to avoid the situation that the display screen cannot be started due to too low temperature.

 

4. Maintenance of heat dissipation

For outdoor LED large screen users, we must pay attention to the temperature change of the LED large screen, because the temperature is too high will lead to the complete destruction of the LED display, it is recommended that the LED display within 20 square meters does not use air conditioning, and two small fans are enough.

 

5. Ventilation measures should be taken inside the screen

If the heat is not discharged and accumulates to a certain extent, it will cause the internal ambient temperature to be too high, which will affect the work of the circuit, and will seriously lead to burnout and the display screen can not run and 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 degrees and 40 degrees.

 

6. Selection of high-brightness wick

The choice of LED tubes with high luminous brightness can allow us to display well in direct sunlight, and can also enhance the contrast with the surrounding environment, so that the audience of the picture is wider, and there is still a good effect in places with a wide distance and a wide viewing angle.
