LED display - knowledge
LED display need to display content, the space site condition, the size of the LED display unit template (
Or pixel size (
, good package edge must be calculated.
LED display of the power consumption is divided into the average power consumption and maximum power consumption.
The average power consumption is also called the working capacity, the actual power consumption is normal.
Maximum power consumption is a startup or on the extreme cases such as power consumption, maximum power consumption is an alternating current power supply (
Wire, switch, etc. )
Must be taken into account, the elements of the average power consumption is commonly 1/3 of the maximum power consumption.
LED display is a large precision electronic equipment, for the sake of the safe use and operation work, its AC220V power input end or AC220V power input end is connected to the computer must be grounded.
LED display is installed outdoors, and often, 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;
LED display may be limited by lightning caused heavy current strong magnetic attack;
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;
At a wide, line-of-sight requirement, vision requires far and wide;
Change of ambient light, and in particular may be direct sunlight.
For the above special requirements, outdoor full-color LED display need to do the following: screen 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;
Install lightning protection device in the LED display and buildings;
Install ventilation cooling equipment, makes the screen body internal temperature in -
Between 40 ℃.
Behind the screen above the installation of axial flow fan, exhaust heat, according to what the use of the screen size axial flow fan;
The outer encapsulation of LED display medium for at present 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 prevention' characteristics.
Also installed outdoor full-color LED display must be careful, must be waterproof, if inadvertent leakage must be drainage work!
Must for lightning protection device, the late must also be prepared to regular inspection, soot cleaning on a regular basis.
