The main problems of outdoor LED screen in shenzhen are as follows:
(1) shenzhen LED large screen is installed in the outdoor, often in the sun, rain, wind and dust cover, poor working environment.If the electronic equipment is wet or seriously damped, it will cause short circuit or even fire, cause fault or even fire, and cause loss;
(2) large LED screens in shenzhen may be attacked by strong electric and magnetic forces caused by lightning;
(3) the ambient temperature varies greatly.Shenzhen LED large screen itself will produce a certain amount of heat when working, if the environment temperature is too high and poor heat dissipation, integrated circuit may not work properly, or even burned down, so that the display system can not work properly;
(4) wide audience, long visual distance and wide visual field;Ambient light varies widely, especially when exposed to direct sunlight.
For the above special requirements, outdoor shenzhen LED screen must be:
(1) the screen body and the joints between the screen body and the building must be strictly waterproof and leakproof;Screen body should have good drainage measures, once water can be discharged smoothly;
(2) install lightning protection devices on LED large screens and buildings in shenzhen.The main body and shell of shenzhen LED large screen are well grounded, and the grounding resistance is less than 3 ohm, so that the large current caused by lightning can be timely discharged;
(3) install ventilation cooling equipment, makes the screen body internal temperature between - 10 ℃ to 40 ℃.Axial flow fan is installed behind and above the screen body to discharge heat;
(4) choose working temperature between - 40 ℃ ~ 80 ℃ of industrial-grade integrated circuit chips, prevent winter temperature is too low to make shenzhen LED large screen cannot start;
(5) in order to ensure the long-distance visibility in the case of strong ambient light, it is necessary to choose ultra-bright led;
(6) the display medium is a new type of wide-angle tube with wide perspective, pure color, consistent coordination and a life span of more than 100,000 hours.The outer packaging of the display medium is the most popular with cover along the square cylinder body, silicone seal, no metal make-up;Its appearance is exquisite and beautiful, strong and durable, with direct sunlight, dust, waterproof, high temperature, short circuit protection "five prevention" features.
