| How to choose and buy outdoor LED electronic screen wall? | ||||
The main questions about the outdoor screen are as follows:
LED electronic screen equipment in the outdoor, often in the 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. The electronic screen may be hit by strong electricity and strong magnetism caused by lightning.
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.
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 requirements, it is necessary for the outdoor LED electronic screen to achieve: the screen body and the junction between the screen body and the building must be strictly waterproof and leak proof; the screen body should have outstanding drainage methods, which can discharge smoothly once the water is accumulated.
Lightning protection equipment shall be installed on electronic screens and buildings. The main body and shell of the electronic screen adhere to excellent grounding, and the grounding resistance is less than 3 ohm, so that the large current caused by lightning can be discharged in time.
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 at the top and back of the screen to discharge heat.
Industrial grade IC chips with operating temperature between - 40 ℃ and 80 ℃ are selected to avoid the electronic screen from starting due to too low temperature in winter.
In order to ensure long-distance visibility in the condition of intense ambient light, it is necessary to select ultra-high brightness LED.
The display medium adopts the new wide viewing angle tube, which has wide viewing angle, pure color, common 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 cover edge, which is sealed with silica gel and has no metallization installation. Its appearance is exquisite and beautiful, and it is durable and has the characteristics of "five prevention" of direct sunlight, dust, water, high temperature and short circuit.
