Outdoor LED display safety operation has to be considered and dealt with

- Jul 09, 2019-

Outdoor led display faces the following problems before installation and use, which must be well handled to ensure the safe operation of led display.


1. Led display screen is installed outdoors.


Often the sun and rain, wind and dust cover, working environment. Electronic equipment is wet or seriously affected by moisture will cause short circuit or even fire, cause failure or even fire, resulting in losses.


Second, led display may be caused by lightning strong electric magnetic attack.


Three, the environment temperature changes greatly.


Outdoor led display will generate a certain amount of heat when it works. If the ambient 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 cannot work normally.


4. Outdoor led display screens are widely available.


Long line-of-sight and wide field of vision; Ambient light varies greatly, especially when exposed to direct sunlight.


Above is the outdoor led display special requirements, in view of these characteristics, the following powerful color small series to summarize the outdoor led display a few points to note.


I. the screen body of led display screen and the combination of the screen body and building must be strictly waterproof and leakproof; Screen should have good drainage measures, once the occurrence of water can be discharged smoothly.


Install lightning protection devices on led display screens and buildings. The main body and shell of the display screen are well grounded, and the grounding resistance is less than 3 ohms, which makes the large current caused by lightning timely discharge.


3. Install ventilation equipment to cool the temperature, so that the internal temperature of outdoor led display screen is between -10℃ and 40℃. An axial fan is installed above and behind the screen to discharge heat.


4. Industrial grade IC chip with working temperature between -40℃ ~ 80℃ is selected to prevent led display screen from starting due to low temperature in winter.


Five, in order to ensure that in the case of strong ambient light remote viewing, outdoor led display screen must choose ultra-bright led.


6. The display medium of led display screen adopts new wide viewing Angle tube, with wide viewing Angle, pure color, consistent coordination, and service life of more than 100,000 hours. The external package of the display medium is the most popular square cylinder with cover, sealed with silica gel, no metal makeup; Its appearance is delicate and beautiful, strong and durable, with direct sunlight, dust, waterproof, high temperature, short circuit prevention "five" characteristics
