Outdoor led display installation precautions: ( 1) 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. 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 screen 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 in - Range of 10 ℃ to 40 ℃. Behind the screen above installed axial flow fan, exhaust heat. Choose working temperature in - Between 40 ℃ ~ 80 ℃ 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 of the two. The installation of outdoor display ways: 1) Column: column installed in suitable for the installation of the led display, outdoor screen is installed on the pillar. Column is divided into single column and double column, in addition to the need to make the screen body steel structure, still need to make concrete or steel columns, mainly considering the geological condition of 2) Mosaic inlay structure suitable for the building project has been included in the planning and designing the screen, in the civil engineering project construction reserved in advance screen installation space, only when the actual installation steel structure will make screen display embedded within the building metope, have enough maintenance space on the back of 3) Rooftop general installation method is fixed on the wall of the screw, the fixed frame, the screen in a framework, even the power cord, ribbon cable, light debugging, can 4) Bridge loading structure is adopted in the ground concrete build by laying bricks or stones a enough to support the whole led display wall wall, construction steel structure installation screen on the wall, steel structure reserved 800 mm space for maintenance, relevant equipment and maintenance facilities
