Problems needing attention and installation precautions of outdoor LED electronic screen

outdoor led wall

The main problems of outdoor LED electronic screen are as follows:
(1) Outdoor LED electronic screen device in the field, often in the sun and rain, wind and dust cover, poor working environment. If the electronic equipment is wet or seriously damped, it will lead to short circuit and even fire, resulting in fault and even fire, resulting in loss;
(2) Outdoor LED electronic screen may be impacted by strong current and strong magnetic field caused by lightning;
(3) The ambient temperature changes greatly. If the environment temperature is too high and the heat dissipation is not good, the integrated circuit may not work normally or even be burned, so that the display system can not work normally;
(4) Outdoor LED electronic screen has a wide audience, a long viewing distance and a wide field of vision; the ambient light changes greatly, especially when it is exposed to direct sunlight.
For the above special requests, it is necessary to achieve the following:
(1) It is necessary to strictly waterproof and leak proof for the LED electronic screen and the junction between the screen body and the building; the screen body should have excellent drainage methods, which can discharge smoothly once the water is accumulated;
(2) Lightning protection equipment is installed on outdoor LED electronic screens and buildings. The main body grounding resistance is less than 3 ohm due to the lightning discharge current;
(3) The ventilation equipment is installed to reduce the temperature, so that the internal temperature of the screen is between – 10 ℃ and 40 ℃. An axial flow fan is installed above the back of the screen to discharge heat;
(4) Industrial grade integrated circuit chips with operating temperature between – 40 ℃ and 80 ℃ are selected to avoid too low temperature in winter to make the display screen unable to start;
(5) In order to ensure long-distance visibility in the case of strong ambient light, it is necessary to select ultra-high brightness LED;
(6) The new wide viewing angle tube is selected as the display medium, which has wide viewing angle, pure color, common harmony and life span of more than 100000 hours. The outer package of display medium is currently the most popular square cylinder with edge shield, which is sealed with silica gel and has no metallization installation. Its appearance is exquisite and beautiful, and it is robust and durable, with the characteristics of “five prevention” of direct sunlight, dust, water, high temperature and short circuit.
