Outdoor LED display should be well protective measures

- Jul 22, 2019-

Outdoor LED display should be installed with protection and maintenance measures to prevent the outdoor environment from affecting the normal use of LED display. So, outdoor LED display to do what protective measures? Shenzhen liansen photoelectric summed up the following points!

Outdoor LED display protection measures:

1. Lightning protection measures for installation buildings and screens

In order to avoid the strong electromagnetic attack caused by lightning, the screen body and the outer packaging protection layer of the display must be grounded, and the resistance of the grounding line should be less than 3 euros, so that the current caused by thunder can be timely drained away from the ground.

2. The whole screen shall be waterproof, dustproof and moisture-proof

Seamless connection should be made between the box body and the box body, as well as the joint of the screen body and the loading installation object to avoid water leakage and damp. In the interior of the screen body to have good drainage ventilation measures, if the internal water situation can be timely treatment.

3. The selection of circuit chips

In the northeast of China, the temperature in winter can generally reach minus 10 degrees Celsius, so in the selection of circuit chips, we must choose the industrial chip with the operating temperature of minus 40 degrees Celsius refers to 80 degrees Celsius, to avoid the situation that the display screen cannot start because of the low temperature.

4. Ventilation measures should be taken inside the screen

When the screen is powered on, certain heat will be generated. If the heat is not discharged and accumulates to a certain extent, the internal environment temperature will be too high, which will affect the work of the integrated circuit. In serious cases, it will burn out, so the screen cannot work. Therefore, it is necessary to do a good job of ventilation and heat dissipation measures in the interior of the screen, and keep the internal temperature between minus 10 degrees and 40 degrees

5, highlight the choice of wick

The LED tube with high luminance is selected, which allows us to have a good display effect in the case of direct sunlight. Moreover, it can enhance the contrast with the surrounding environment, making the picture more broad for the audience. In the place with a long distance and a wide perspective, it still performs well.
