With the continuous development of led display technology, the variety of led display products has become more and more abundant, and its application scenarios have become more and more widely. Arrived, the weather is getting hotter and hotter, however, the outdoor large-scale strawberry music festival, the tour performance is basically the beginning of this season from the trend of previous years. The installation of outdoor led display should take protective and maintenance measures to prevent the outdoor environment from affecting the normal use of led display. How does outdoor LED display dissipate heat and prevent rain?

 Outdoor led display protection measures:

1. Lightning protection measures for installation buildings and screens

 In order to prevent the LED display from being attacked by strong electromagnetic waves caused by lightning, the screen body and the outer packaging protective layer of the LED display must be grounded, and the resistance of the grounded line should be less than 3 ohms, which can make the current caused by lightning It can be drained from the ground wire in time.

2. Waterproof, dustproof and moistureproof measures for the entire screen

 The connection between the box and the box, as well as the joint between the screen and the stressed installation object, should be seamlessly connected to avoid water leakage and moisture. The interior of the screen should have good drainage and ventilation measures. If there is water accumulation inside, it can be dealt with in time.

3. About the selection of circuit chips

 In the northeastern region of my country, the temperature in winter can generally reach minus ten degrees, so when selecting circuit chips, it is necessary to choose an industrial-grade chip with an operating temperature of minus 40 degrees Celsius, which means 80 degrees Celsius, to avoid the occurrence of excessive temperature. Low causes the display to fail to start.

4. Maintenance of heat dissipation

 For outdoor LED display users, we must pay attention to the temperature change of the LED display. Due to the high temperature, the LED display will be completely destroyed. It is recommended that the LED display within 20 square meters does not use an air conditioner. A fan is enough.

5. Take ventilation measures inside the screen

 When the screen is powered on, it will generate a certain amount of heat. If the heat cannot be discharged and accumulated to a certain level, the internal ambient temperature will be too high, which will affect the work of the integrated circuit. The display does not work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures inside the screen body, and the temperature of the internal environment should be kept between minus 10 degrees and 40 degrees.

6, the choice of high-bright wick

 The selection of high-brightness LED lamps allows us to still display good results in direct sunlight, and can also enhance the contrast with the surrounding environment, making the picture wider for the audience. There are still good performances.
