led display wall content needs, space conditions, led display unit template size (indoor screen) or pixel size (outdoor led screen), the edge must be calculated. the power consumption of led display is divided into average power consumption and maximum power consumption. average power consumption, also known as working power consumption, is the actual power consumption in peacetime. maximum power consumption is the power consumption in extreme conditions such as startup or full brightness. maximum power consumption is an important factor to be considered in ac power supply (line diameter, switch, etc.). the average power consumption is generally 1/3 of the maximum power consumption. led display is a large-scale precision electronic equipment. in order to use safely and operate, the ac 220v power input terminal or the ac 220v power input terminal of the computer connected to it must be grounded.
the led display is installed outdoors, often in the sun and rain, and the working environment is bad. wetting or serious dampness of electronic equipment will cause short circuit or even fire, causing failure or even fire, causing losses; led display may be attacked by strong electric and magnetic fields caused by lightning; environmental temperature changes greatly. if the ambient temperature is too high and the heat dissipation is not good, the integrated circuit may work abnormally or even be burned down, which makes the display system unable to work properly; wide audience, long visual distance and wide field of vision; great changes in ambient light, especially possibly directly exposed to sunlight.
in view of the above special requirements, outdoor full-color led display needs to do the following: the screen body and the interface between the screen body and the building must be strictly waterproof and leak-proof; the screen body should have good drainage measures, once water accumulated can be discharged smoothly; lightning arresters should be installed on the led display screen and buildings; ventilation equipment should be installed to cool down so as to make the inner temperature of the screen body. degree ranges from – 10 to 40 degrees celsius. install an axial-flow fan behind and above the screen body to discharge heat. according to the size of the screen body, how many axial-flow fans are used?
