        With the continuous development of LED display technology, led display products are becoming more and more diversified, and its application scenarios are becoming more and more extensive. Due to the difference in temperature between indoor and outdoor use, the maintenance and protection work is also different, especially in summer, when the weather is very hot and humid. However, large outdoor strawberry music festival, tour shows from the trend of previous years are basically popular in this season. Next, lian Cheng hair xiaobian to introduce you to outdoor LED display protective measures!

   

Outdoor LED display protection measures:


1. Lightning protection measures for the installation of buildings and screens. In order to avoid strong electromagnetic attacks caused by lightning, the screen body and the outer protective layer of the LED display must be grounded, and the resistance of the grounding line should be less than 3 Ohms, so that the current caused by lightning can be discharged from the ground in time.


2, the whole screen of waterproof, dustproof and moistureproof measures in the box body and box body connection, as well as the screen body and force installation object joint to do seamless connection, to avoid moisture leakage. In the interior of the screen body to have a good drainage ventilation measures, if there is water inside the situation can be timely treatment.


3, about the circuit chip selection problem Northeast region in China, the winter air temperature in the generally can reach to ten below zero, so in choosing a circuit chip, must choose working temperature at minus 40 degrees Celsius to 80 degrees Celsius degrees of industrial-grade chip, avoid caused by low temperature display won't start.


4, the maintenance of heat dissipation for outdoor LED display users, we must pay attention to the temperature change of LED display, because the temperature is too high will lead to the complete destruction of LED display, it is recommended that the LED display does not use air conditioning within 20 square, using two small fans is enough.


5, the screen body to do a good job of ventilation measures when the screen body power operation will produce a certain amount of heat, if the heat can not be discharged, accumulated to a certain extent, will cause the internal environment temperature is too high, affect the work of the integrated circuit, serious can lead to burn, so far the screen can not operate. Therefore, it is necessary to do a good job of the internal ventilation and heat dissipation measures of the screen body, the temperature of the internal environment is kept between minus 10 degrees to 40 degrees.


6, the choice of the high brightness of the LED lamp wick, can let us in direct sunlight, still show good effect, but also can enhance the contrast with the surrounding environment, so that the picture of the audience is wider, in a far distance, a broad perspective of place, still have good performance.
