Points for attention in the installation of outdoor LED display
With the popularization and application of LED displays, the diversified development of LED display products such as full-color LED displays and large LED screens has greatly increased people’s colorful world. Today’s LED displays are more widely used in all walks of life. In all industries, whether it is a campus, a station, a square, etc., the visual effects brought by LED displays add vitality and vitality, especially outdoor LED displays. However, in the practical application of outdoor LED display, the installation of outdoor LED display has become the focus of attention, so what are the points of attention for the installation of outdoor LED display?
1. Pay attention to the lightning protection of buildings and screens: In order to protect the display from strong electromagnetic attacks caused by lightning, the screen and the outer packaging protective layer of the display must be grounded, and the resistance of the grounded line should be less than 3 ohms. In this way, the current caused by lightning can be drained from the ground wire in time.
2. The problem of waterproof, dustproof and moistureproof of the entire screen: seamless connection should be made at the connection between the box and the box, as well as the joint between the screen and the installation object under force, 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. The selection of circuit chips: In the northeastern region of my country, the temperature in winter can generally reach minus ten degrees, so when choosing circuit chips, it is necessary to choose an industry with a working temperature of minus 40 degrees Celsius, referring to 80 degrees Celsius. level chip to avoid the situation that the display screen cannot be started due to too low temperature.
4. Ventilation should be done inside the screen body: when the screen body is energized and operated, a certain amount of heat will be generated. If the heat cannot be discharged and accumulated to a certain extent, the internal ambient temperature will be too high, which will affect the integrated circuit. The work will be affected, and in severe cases, it can lead to burnout, so far the display screen cannot 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.
