installation scheme of outdoor LED electronic screen wall

The main problems of outdoor LED electronic screen in planning equipment are as follows:
(1) Electronic screen equipment in the outdoor, often sun and rain, wind blowing dust cover, the working environment is bad. 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) The electronic screen may be impacted by strong electricity and strong magnetic field caused by lightning;
(3) The ambient temperature changes dramatically. 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) The range of the audience is wide, the range of vision is far, and the range of vision is wide; the ambient light changes greatly, especially when exposed to direct sunlight.
For the above special requests, it is necessary for outdoor LED electronic screen to:
(1) It is necessary for the screen body and the joint of the screen body and the building to be strictly waterproof and leakproof; the screen body should be provided with good drainage measures, which can discharge smoothly in case of water accumulation;
(2) Lightning protection equipment shall be installed on electronic screens and buildings. The main body and shell of the electronic screen shall be well grounded, and the grounding resistance shall be less than 3 ohm, so as to release the large current caused by lightning in time;
(3) The ventilation equipment of the equipment is cooled to make the internal temperature of the screen body between – 10 ℃ and 40 ℃. An axial fan is installed above the back of the screen to discharge heat;
(4) Industrial grade IC chips with operating temperature between – 40 ℃ and 80 ℃ are selected to prevent the electronic panel from starting due to too low temperature in winter;
(5) In order to ensure long-distance visibility in the case of intense 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, consistent harmony, and has a life span of more than 100000 hours. The outer package of the display medium is the most popular square cylinder with edge shield, which is sealed with silica gel and has no metallization installation. It is beautiful in appearance and durable in structure, and has the characteristics of “five prevention” of direct sunlight, dust, water, high temperature and short circuit.
