Protective Measures for LED Display

Protective measures for LED display
Outdoor LED display installations should take protective and maintenance measures to prevent the outdoor environment from affecting the normal use of LED displays.
Outdoor LED display protective measures:
1. Lightning protection measures for installation buildings and screens
In order to protect the display screen from strong electromagnetic attacks caused by lightning, the screen body and the outer packaging protection 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 timely is discharged from the ground wire.
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. 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, and the temperature of the internal environment should be kept between minus 10 degrees and 40 degrees.
5, 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.
