Outdoor full-color LED display controls the natural factors
Dry weather, outdoor natural disasters occurred frequently, of course, as a bear the brunt of the outdoor full-color LED display, electronic screen by lightning fell on drying sundries cause fire. Energy efficient and environmentally friendly full-color LED display for natural disasters, cases, how shall we go to handle the scene? A, LED electronic display quality factors, there are two factors | Atop the LED Opto Electronic1, material factors: a screen by, LED lamps, IC, PCB, hardware, software and so on, if the material is not high, the LED light source is insufficient, chip burn out or does not work, PCB line is not stable, the hardware configuration is too low, programming software control program does not reach the designated position, and so on related are the problems of material, will influence. 2, environmental factors, such as: outdoor screen: no good protection, high temperature, rain, thunder and lightning, wind conditions make electronic equipment such as serious be affected with damp be affected with damp cause short circuit or fire, etc. Environment temperature is an important internal itself, as the change of outside temperature changes, such as heat dissipation not ready, it can lead to heat dissipation, operation of the integrated temperature is too low will be affected as well, so the need of ventilation, air conditioning and other equipment, to control the temperature. Environmental factors also depends on a parameter of the LED display, effective range relation with actual field size, resolution, screen size, brightness, screen device of bearing and so on, this is a factor influencing ornamental quality. Second, should be considered for outdoor electronic screen 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; 2, LED display may be limited by lightning caused heavy current strong magnetic attack; 3, the environment temperature changes greatly. 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; 4, at a wide, line-of-sight requirement, vision requires far and wide; Change of ambient light, and in particular may be direct sunlight. More than three, according to special requirements, the outdoor screen must be: 1, LED display 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; 2, in the lightning protection devices are installed on the screen and buildings. 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; 3, 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; 4, choose working temperature in - Between 40 ℃ ~ 80 ℃ industrial-grade integrated circuit chips, prevent winter low temperature display can not start; 5, in order to ensure that in the case of the ambient light strong visual over a long distance, must choose high brightness leds; 6, choose new wide-field tube display medium, 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.
