Installation och installation av utomhus LED-skärmar

(1) LED-skärmar installeras utomhus, ofta utsatt för solljus, regn, vind och damm, and have a harsh working environment. Electronic devices that are wet or severely damp can cause short circuits or even fires, leading to malfunctions or even fires, causing losses;
(2) The display screen may be subjected to strong electrical and magnetic attacks caused by lightning;
(3) Omgivningstemperaturen varierar kraftigt. When the display screen is working, it must generate a certain amount of heat. Om den omgivande temperaturen är för hög och värmeavledningen är dålig, the integrated circuit may not work properly, or even be burned out, thereby making the display system unable to work properly;
(4) Bred publik, long visual range and broad field of vision required; Det omgivande ljuset varierar kraftigt, especially when exposed to direct sunlight.

For the above special requirements, utomhus LED-display screens must achieve:
(1) The screen and the junction between the screen and the building must be strictly waterproof and leak proof; The screen should have good drainage measures to ensure smooth drainage in case of accumulated water;
(2) Install lightning protection devices on display screens and buildings. The main body and casing of the display screen should be well grounded, with a grounding resistance of less than 3 ohms, to timely discharge large currents caused by lightning;
(3) Install ventilation equipment to cool down and keep the internal temperature of the screen between -10 ℃ och 40 ℃. Install an axial fan above the back of the screen to dissipate heat;
(4) Select industrial grade integrated circuit chips with operating temperatures between -40 ℃ och 80 ℃ to prevent the display screen from being unable to start due to low temperatures in winter.;
(5) In order to ensure long-distance visibility under strong ambient light, ultra-high brightness light-emitting diodes must be selected;
(6) The display medium uses a new type of wide-angle tube, which has a wide viewing angle, pure colors, konsekvent samordning, and a lifespan of over 100000 timmar. The outer packaging of the display medium is currently the most popular square cylinder with a covered edge, sealed with silicone, and equipped without metalization; Dess utseende är utsökt och vackert, sturdy and durable, with the characteristics of being resistant to direct sunlight, damm, vatten, high temperature, and circuit short circuits.
