Precautions for outdoor LED display installation

Want to do mobile LED advertising car, what need to pay attention to, no experience, seek the guidance of knowledgeable.


for outdoor LED display, Because it is used outdoors,
it is necessary to treat it differently from ordinary indoor LED display.
the installation requirements of outdoor LED display are different from ordinary indoor LED display.
the details of installation must be done well.
otherwise, it is likely to cause trouble.

six ideas for outdoor LED display installation
1. Install lightning protection devices on display and buildings.
2
The main body and shell of the display screen shall be well grounded.
the grounding resistance shall be less than 3 ohm, so that the large current caused by lightning can be discharged in time; The display screen may be attacked by strong electricity and strong magnetic field caused by lightning. 2. The waterproof measures of LED display screen itself
the screen body and the joint between the screen body and the building must be strictly waterproof and leak proof; The screen body should have good drainage measures, once the ponding occurs, it can be discharged smoothly; Pay attention to water-proof and moisture-proof.
the display screen is installed outdoors.
it is often exposed to the sun, rain, wind and dust, and the working environment is harsh.
the electronic equipment is wet or seriously affected with moisture, which will cause short circuit or even fire.
it will cause failure or even fire, resulting in losses; 3. Select the industrial IC chip whose working temperature is between - 40 ℃ and 80 ℃ to prevent the display screen from being unable to start due to low temperature in winter.

4. Install ventilation equipment to reduce the temperature.
make the internal temperature of the screen between - 10 ℃ and 40 ℃.
install axial flow fan on the back and top of the screen to discharge heat; When the display screen works, 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 normally, or even be burned, so that the display system can not work normally
5. Ultra high brightness LED must be selected
in order to ensure long-distance visibility under strong ambient light,Ultra high brightness LED must be selected; Increase contrast. Wide audience, long sight distance and wide field of vision; The environment light changes greatly, especially may be exposed to direct sunlight.
6. The display medium is a new wide viewing angle tube with wide viewing angle.
the color is pure, consistent and coordinated, and the service life is more than 100000 hours. The external packaging of the display medium is the most popular square cylinder with shielding edge, sealed with silica gel, and no metallization assembly; Its appearance is exquisite and beautiful, solid and durable, with the characteristics of direct sunlight, dust prevention, waterproof, high temperature, short circuit prevention.

the installation precautions of outdoor LED electronic display involve the use and safety of the product in the future.
we must take it seriously, mainly whether it can be used on the road after modification, and whether the urban management and traffic police will stop the fine
