What should be paid attention to when installing outdoor LED advertising screens


What should be paid attention to when installing outdoor LED advertising screens? Outdoor LED advertising screens are usually installed on outdoor buildings, or on pillars on squares and roadsides. The working environment is quite harsh. Many customers do not know where to install LED advertising screens. It needs to be paid attention to. Today we will specifically talk about the problems we have encountered for outdoor LED advertising screens. The first is the installation method. What kind of structure needs to be made to perfectly fit the site environment. LED advertising screens need 380V three-phase five-wire power supply, and strong cables need to be laid from the power distribution room or transformer to the screen body distribution cabinet. Outdoor LED advertising screens A control room is needed to modify some information that is usually played on the screen. It is best to prepare a small room of 4-6 square meters for the operator to use. These points are often overlooked. There are also some details, such as the needs of the display content of the LED advertising screen, the space conditions of the site, the size of the LED advertising screen unit template (indoor screen) or pixel size (outdoor screen), and the edge must be calculated.

The power consumption of LED advertising screens is divided into average power consumption and maximum power consumption. Average power consumption, also known as working power, is the actual power consumption in normal times. The maximum power consumption is the power consumption in extreme situations such as startup or full brightness. The maximum power consumption is an element that must be considered for AC power supply (wire diameter, switch, etc.), and the average power consumption is generally 1 of the maximum power consumption. /3.

The LED advertising screen is a large precision electronic device. In order to use it safely and work safely, its AC220V power input terminal or the AC220V power input terminal of the computer connected to it must be grounded. In view of the above special requirements, the outdoor full-color LED advertising screen needs to do the following: the screen body and the joint between the screen body and the building must be strictly waterproof and leak-proof; the screen body must have good drainage measures, and once water accumulation occurs, it can be discharged smoothly; Install lightning protection devices on LED advertising screens and buildings; install ventilation equipment to cool down, so that the internal temperature of the screen is between -10°C and 40°C. An axial flow fan is installed on the back of the screen to discharge heat, and how many axial flow fans are used according to the size of the screen; the LED advertising screen is installed outdoors, often exposed to the sun and rain, and the working environment is harsh.

Wet or severely damp electronic equipment will cause short circuits or even fires, causing failures or even fires, resulting in losses; LED advertising screens may be attacked by strong electricity and magnetism caused by lightning; the ambient temperature changes greatly. When the LED advertising screen is working, it will generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally; the audience is wide and the viewing distance is required. 1. Wide field of view is required; the ambient light changes greatly, especially it may be exposed to direct sunlight. The outer packaging of the LED advertising screen medium is currently the most popular square cylinder with a cover, sealed with silicone, and without metallized assembly; Circuit short circuit "five prevention" features.

Therefore, you must be cautious when installing outdoor full-color LED advertising screens, and you must do a good job of waterproofing. If you accidentally leak water, you must do a good job of drainage! The large-scale outdoor LED advertising screen of Lianhuiye must be equipped with lightning protection devices, and regular inspections and dust removal must also be done in the later stage. .
