Analysis of key points in choosing outdoor LED screens

The working environment of outdoor LED screens is much more complicated. Many users are not satisfied with the effect and stability of LED screens due to lack of professional knowledge for the first installation. As a provider, it is necessary to explain in detail the relevant configurations of LED screens and the difference and stability of display effects to users. Sex, you can't just use low prices to induce users to make a one-shot sale and endless after-sales services. Waterproof measures for the LED screen itself: pay attention to waterproof and moisture-proof, the LED screen is installed outdoors, often exposed to the sun and rain, the wind blows the dust cover, and the working environment is harsh. Wet or severe damp of electronic equipment will cause short circuit or even fire, causing failure or even fire, resulting in losses; the joint part of the LED screen box and the steel structure must be strictly waterproof and leak-proof; the LED screen box must have good drainage measures, once Water accumulation can be discharged smoothly.

Lightning protection devices should be installed on led screens and buildings: the main body and shell of led screens should be well grounded, and the grounding resistance should be less than 3 ohms, so that the large current caused by lightning can be released in time; led screens may be attacked by strong electricity and magnetism caused by lightning. Circuit chip selection: select industrial-grade integrated circuit chips with an operating temperature between -40°C and 80°C to prevent the led screen from being unable to start when the temperature is too low in winter. Ultra-high-brightness light-emitting diodes must be selected: in order to ensure long-distance visibility under strong ambient light, ultra-high-brightness light-emitting diodes must be selected; increase contrast, wide audience, long viewing distance, and wide field of view; large changes in ambient light , especially may be exposed to direct sunlight.

Install an axial fan above the LED screen to discharge heat: the LED screen itself will generate a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally. ; Install ventilation equipment to cool down, so that the internal temperature of the LED display screen box is between -10°C and 40°C. The display medium adopts a new type of wide-angle tube: wide viewing angle, pure color, consistent coordination, and a life span of more than 100,000 hours. The outer package of the display medium is the most popular square cylinder with a cover, silicone seal, and no metallized assembly; its appearance Exquisite and beautiful, sturdy and durable, it has the characteristics of preventing direct sunlight, dustproof, waterproof, high temperature and short circuit. The above points will play a vital role in the LED screen. In the design stage of the LED screen, all factors must be considered in an all-round way. The display effect and life extension of the LED screen can be fully guaranteed. If the cost of remediation later will increase a lot, The cost of personnel going back and forth will be significant.
