Outdoor LED full-color screen how to heat and rain?

Due to the different temperatures for indoor and outdoor applications, their maintenance and protection work is also different. Summer is coming and the weather is getting hotter and hotter. However, the outdoor large strawberry Music Festival, From the trend of previous years, touring is basically popular this season. Protective and maintenance measures shall be taken for the installation of outdoor LED full-color screen to prevent the outdoor environment from affecting the normal use of LED full-color screen. Outdoor LED display how to heat and rain?

Outdoor LED full-color screen protection measures:

1. Lightning protection measures for installation buildings and panels

In order to prevent the LED full-color screen from strong electromagnetic attack caused by lightning, the screen body and external packaging protective layer of the LED full-color screen must be grounded, and the resistance of the grounded line should be less than 3 Ω, so that the current caused by lightning can be discharged from the ground line in time.

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

Seamless connection shall be achieved at the connection between the box and the box, as well as the connection between the screen and the stressed installation object to avoid water leakage and moisture. Good drainage and ventilation measures shall be provided inside the screen body. If there is ponding inside, it can be treated in time.

3. On the selection of circuit chips

In Northeast China, the temperature in winter can generally reach more than ten degrees below zero. In this way, when selecting circuit chips, we must select industrial chips with working temperature of minus 40 degrees Celsius, which means 80 degrees Celsius, so as to avoid the situation that the display screen cannot be started due to low temperature.

4. Maintenance of heat dissipation

For outdoor LED full-color screen users, we must pay attention to the temperature change of LED full-color screen. Because too high temperature will lead to the complete destruction of LED full-color screen, it is recommended that the LED full-color screen within 20 square meters do not use air conditioner, and two small fans are enough.

5. Ventilation measures shall be taken inside the screen

Certain heat will be generated when the screen is powered on for operation. If these heat cannot be discharged and accumulated to a certain extent, the internal ambient temperature will be too high, which will affect the operation of the integrated circuit. In serious cases, it can lead to burning. So far, the display can not operate. Therefore, the ventilation and heat dissipation measures inside the screen must be taken, and the temperature of the internal environment must be kept between minus 10 degrees and 40 degrees.

6. Highlight the selection of the wick

The selection of LED tubes with high luminous brightness can not only make us still have good display effect in the case of direct sunlight, but also enhance the comparison with the surrounding environment, make the audience of the picture wider, and still have good performance in places with long distance and wide viewing angle.
