Surrounded by thousands of smog, "I" remain unmoved! LED display screens have clever tips for preventing haze

Since the beginning of winter, many provinces and cities, led by Beijing, have been hit by smog. No, after Beijing issued a red alert for heavy air pollution for the first time on December 8, ten days later, Beijing issued a red alert for air pollution again. Misfortunes never come singly. In the early hours of this morning, Tianjin, adjacent to Beijing, also issued its first red air pollution warning through the "Tianjin Release" official Weibo and other channels. For a time, Weibo and Moments were filled with haze, and all kinds of jokes came in: "Prevent fire, theft, and haze!" "Has anyone ever made you so heartbroken that you can't breathe? Yes, haze!" "Beijing, Shanghai and Guangzhou don't believe in tears, Jiangsu, Zhejiang, and Shanghai." Don’t dry the quilt, Liao, Jihei and Heilongjiang don’t believe in getting drunk. You must have good lungs in Beijing, Tianjin and Hebei.”

In order to minimize the harm of haze to the human body, various air forecasts and air purifiers are emerging: IBM. The National Research Institute has developed an air quality prediction and management system that can generate high-resolution air quality prediction analysis 72 hours in advance; Xiaomi has launched a new generation of smart air purifiers designed and manufactured by its ecological chain enterprise Zhimi Technology - Xiaomi Air Purifier 2; Philips has developed an air purifier Smartair 330, which realizes the function of making an appointment to complete the purification before getting in the car, which cannot be achieved by other purifiers, and enjoying fresh air immediately after getting in the car.

As a landscape in the city, LED display screens that integrate information release, entertainment, and publicity functions are certainly not immune to disasters. It is understood that moisture in haze can easily short-circuit LED displays, while dust and tiny particles in the air will reduce the heat dissipation and insulation performance of LED displays, accelerate the aging of the display, and affect its normal service life. Smart LED people, in order to make the LED display screen shine even in hazy days, have taken various measures in product innovation and physical haze prevention.

First of all, in terms of product innovation, Shanghai Qingsong independently developed Artemis It is easy to cope with haze weather; Getron adopts a unique module all-aluminum shell design, the IC and PCB adopt a hidden design, the entire aluminum bottom shell is responsible for heat dissipation and waterproofing, and the rear end terminal of the module is equipped with a rain cover made of precision grinding tools. The module has a "immersion" waterproof effect...

As for physical anti-haze, generally speaking, LED displays are mostly exposed to the outdoors, so when purchasing an LED display, you should pay attention to whether the PCB board of the LED display has been treated with anti-corrosion treatment; whether the power supply and power cord are high-quality accessories; and whether the welding joint of the screen body is the most susceptible to corrosion, and whether it has been treated with anti-rust treatment. At the same time, in daily maintenance projects, dust is removed regularly and used for more than 1 hour a day in hazy weather to reduce the erosion of the display screen by moisture. In addition, you should pay attention to whether the purchased LED display meets the dust-proof level required by the use environment. If it is used in northern areas with a lot of sand and haze weather, it must reach Level 6 dust-proof (completely dust-proof structure). In areas with a lot of haze weather, the protection level of the front and back of the LED display must reach IP65, that is, the LED display adopts a completely dust-proof structure and is sealed when sprayed with water.

Today, large-scale smog will reach its peak. Beijing-Tianjin-Hebei, Liaoning, Shandong, Henan, Anhui, and Jiangsu are mostly moderately to severely polluted, and the North China Plain is the highest level of severe pollution. North China will usher in weak cold air this week. Although the haze fluctuates, it will generally remain the same. If you want to see blue skies, you need to wait until Sunday. We hope that through everyone's joint efforts, there will be a blue sky in the future.
