At present, outdoor LED display screen
is a kind of propaganda media which is widely used in outdoor advertisement. It has a wide audience, diversified forms of advertisement and is favored by advertising companies. So what are the problems we should pay attention to when we install the outdoor LED display
? Here are some points for attention in outdoor LED display installation.
1.we must choose ultra-high brightness light emitting diodes: in order to ensure long-distance visibility in the case of strong ambient light, we must choose ultra-high brightness light emitting diodes; increase the contrast. wide audience, long visual distance, wide vision requirements; large changes in ambient light, especially the possibility of direct sunlight.
2.Waterproof measures of outdoor LED display screen
itself: the screen and the joint of the screen and the building must be strictly waterproof and leak-proof; the screen should have good drainage measures, once the water can be discharged smoothly; pay attention to waterproof, moisture-proof. The display screen is installed in the open air, and is often exposed to the sun and rain. Wetting or serious dampness of electronic equipment can cause short circuit or even fire, causing failure or even fire, causing losses.
and lightning arresters installed on buildings: outdoor LED display maintains a good grounding between the main body and the shell, grounding resistance is less than 3 ohms, so that the lightning-induced large current timely release; display screen may be caused by lightning-induced strong electric magnetic attack.
4.Install ventilation equipment to cool down, so that the inside temperature of the screen is between - 10 ~40. Install axial fan behind and above the screen to discharge heat; the display itself will produce 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 properly, or even be burned down, so that the display can be displayed. The system is not working properly.
5.display medium selection of new wide-angle tube: wide angle of view, pure color, consistent and coordinated, more than 100,000 hours of life display medium packaging for the current most popular with shelter along the square cylinder, silicone seals, non-metallized assembly; its exquisite appearance, solid and durable, with direct sunlight, dust, waterproof, waterproof, anti-corrosion High temperature, anti circuit short circuit five features.
6.the choice of circuit chip: choose the industrial integrated circuit chip whose working temperature is between - 40 ~80 ~C to prevent the display screen
from starting when the temperature is too low in winter.
Outdoor LED display installation considerations related to the use of products and safety, must be taken seriously.
