For outdoor full color LED display
, because it is used in outdoor.
So the inevitable to and ordinary indoor LED display differently.
Also on the outdoor LED display installation requirements and is not the same as the normal indoor LED.
On the installation must be well in detail.
Or is likely to cause trouble.
Let GKGD photoelectric summarizes the installation of outdoor LED screen for you attention!
Outdoor LED display install six idea items: 1, building lightning protection devices are installed on the display screen and main body and the shell to keep good grounding, grounding resistance is less than 3 ohm, lightning causes a large current discharge in a timely manner;
Screen may be heavy current strong magnetic attacks caused by lightning.
2, LED display screen itself waterproof measures of body and screen and the integration of a building must be strictly waterproof leakage protection;
Screen should have good drainage measures, in the event of water discharge smoothly;
Pay attention to waterproof, moistureproof.
Screens installed outdoors, and often, the wind dust cover, poor working conditions.
Electronic equipment is wet or seriously be affected with damp be affected with damp will cause a short circuit or even fire, fault and even fire, loss;
3 in the selection, choice of circuit chips working temperature
Between 40 ℃ ~ 80 ℃ industrial-grade integrated circuit chips, prevent winter low temperature display cannot start.
4, install ventilation cooling equipment, makes the screen body internal temperature in -
Range of 10 ℃ to 40 ℃.
Behind the screen installed above the axial flow fan exhaust heat;
Display itself will generate a certain amount of heat at work, if the environment temperature and heat dissipation, integrated circuit may not work properly, and even destroyed, so that the display system cannot work normally;
5, must use high brightness leds in order to ensure that under the condition of the ambient light strong visual over a long distance, must choose high brightness leds;
Increase the contrast.
At a wide, line-of-sight requirement, vision requires far and wide;
Change of ambient light, and in particular may be direct sunlight.
6, according to media use new wide tube perspective is wide and the color is pure, consistent coordinate, life over 100000 hours display medium outside packaging is the most popular belt along the square cylinder, silicone seal, no metal cosmetic;
Its appearance delicate and beautiful, durable, resistant to direct sunlight, dustproof, waterproof, anti high temperature, prevent short circuit five characteristics.
Through the above GKGD photoelectric attention for the installation of outdoor LED display, I believe you in common use and safety of the outdoor LED to better understanding.
Subsequent GKGD photoelectric will bring you more knowledge about the full color LED display is introduced.
