Precautions for installation of outdoor LED display
1. Lightning protection measures for installed buildings and screens
In order to protect the display screen from strong electromagnetic attack caused by lightning, the screen body and outer packaging protective layer of the display screen must be grounded, and the resistance of the grounded circuit should be less than 3 Ω, so that the current caused by lightning can be discharged from the ground wire in time.
2. Waterproof, dustproof and moisture-proof measures for the whole screen
The joint between the box and the box, as well as the joint between the screen and the stressed installation object, shall be seamlessly connected to avoid water leakage and moisture. Good drainage and ventilation measures shall be taken in the interior of the screen body, so that if there is water accumulation in the interior, it can be treated in time.
3. On the selection of circuit chips
In the northeast of China, the temperature in winter can generally reach minus 10 degrees Celsius, so when selecting circuit chips, you must select industrial chips with working temperature of minus 40 degrees Celsius to 80 degrees Celsius, to avoid the situation that the display screen cannot start due to low temperature.
4. Ventilation measures shall be taken inside the screen
When the screen is powered on, it will generate a certain amount of heat. If the heat cannot be discharged and accumulated to a certain extent, it will cause the internal ambient temperature to be too high, which will affect the operation of the integrated circuit. In serious cases, it can cause burning and the display screen cannot operate. Therefore, ventilation and heat dissipation measures must be taken inside the screen, and the temperature of the internal environment should be kept between minus 10 degrees and 40 degrees.
5. Selection of highlighted wick
The selection of LED tubes with high luminous brightness can make us display well in direct sunlight, and can also enhance the contrast with the surrounding environment, so that the audience of the picture will be wider, and there will still be good performance in places with far distance and wide angle of view.
