Outdoor LED display area is larger, the steel structure design should consider basic, wind load and earthquake magnitude, waterproof, dustproof, environmental temperature, lightning protection, and many other factors.
Placed inside the steel structure to power distribution cabinet, air conditioning, axial flow fan, lighting and other auxiliary equipment, also have., maintenance facilities such as gym.
The whole structure of outdoor LED display to conform to the following IP65 protection class.
Outdoor LED display installation considerations:
(1) LED display is 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.
Screen and screen and building the junction must be strictly waterproof leakage protection;
Screen should have good drainage measures, in the event of water discharge smoothly.
(2) LED display may be heavy current strong magnetic attacks caused by lightning.
In the lightning protection devices are installed on the LED display screen and buildings.
LED display the 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.
(3) the environment temperature changes greatly.
LED 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.
Install ventilation cooling equipment, makes the screen body internal temperature between - 10 ℃ to 40 ℃.
Behind the screen above installed axial flow fan, exhaust heat.
Choose working temperature between - 40 ℃ ~ 80 ℃ of industrial-grade integrated circuit chips, prevent winter low temperature display cannot start.
(4) at a wide, line-of-sight requirement, vision requires far and wide;
Change of ambient light, and in particular may be direct sunlight.
With the direct sunlight, dustproof, waterproof, prevent heat, prevent short circuit "five prevention" characteristics
Outdoor LED display installation safety
1, LED screen brightness is too high
LED display stand on the side of the road, if brightness is moderate, the information can bring convenience to pedestrians and vehicles, but if the LED screen is too bright, make people feel very dazzling, if the driver is reading, may lead to traffic accidents, it is recommended that the LED display screen can be adjusted automatically according to the brightness of the sky brightness.
2, steel structure is not strong enough
When installing LED display structure is strong enough, to consider the heavy rainfall and strong wind weather and earthquake resistant level, and will need to be set to a certain Angle, so that to ensure the safety of the structure stability, and beautify the city, and to spread the information, businessmen can also get advertising revenue.
3, fire prevention lightning protection
LED display is a circuit board, plastic pan and mask.
If the PCB short circuit, or heat treatment well, cause combustion.
Production of LED display, want to notice the use of fire prevention materials, so as not to appear a fire hazard.
As a result, the fireproofing performance of LED display materials, screen body internal heat dissipation function key consideration.
