Outdoor led display faces the following questions before install and use, the safe operation of the led display to have to deal with these problems. A, led display is installed in outdoor. 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. Second, the led display can be caused by lightning heavy current strong magnetic attacks. Three, the environment temperature changes greatly. Outdoor 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. Four, outdoor led display at a wide. Line-of-sight requirement, vision requires far and wide; Change of ambient light, and in particular may be direct sunlight. The above is the special requirements of outdoor led display, according to the characteristics of these powerful giant colour below small make up to summarizes the outdoor led display several matters needing attention. A, led display screen and the screen and the integration of a building must be strictly waterproof leakproof; Screen should have good drainage measures, in the event of water discharge smoothly. Second, in the led display screen and buildings are installed on the lightning protection device. Display the main body and the shell good grounding, grounding resistance is less than 3 ohm, lightning causes a large current discharge in a timely manner. Third, installation of ventilation and cooling, the internal temperature of the outdoor led display in - Range of 10 ℃ to 40 ℃. Behind the screen above installed axial flow fan, exhaust heat. Fourth, choose working temperature in - Between 40 ℃ ~ 80 ℃ industrial-grade integrated circuit chips, prevent winter temperature is too low to make led display can not start. Five, in order to ensure that in the case of the ambient light strong visible at a distance, outdoor led display must use high brightness leds. Six, led display screen display medium choose new wide-field tube, a broad perspective, color pure, consistent coordinate, life over 100000 hours. Display medium outer packaging for 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.
