In summer, accompanied by thunderstorms and a long rainy season, there is also summer. The typhoon has a great impact on coastal cities. Large areas of rain put forward higher protection requirements for the led display screen to prevent lightning strikes.
1. Outdoor led display screen is wind and earthquake resistant.
As outdoor LED display advertisements become more and more widely used, the installation forms of LED displays are becoming more and more diverse, including wall hanging, inlay, suspended ceiling, roof, pillars, etc. In order to avoid the falling of the led display device, there are strict requirements on the selection of wind load and seismic performance and load-bearing steel structure steel, especially the requirements for roof installation and installation columns are more stringent than other forms.
2. Lightning protection measures for outdoor led large screens.
In order to ensure a good grounding, all metal boxes and back covers of the led display device have independent grounding terminals. The terminals are waterproof fasteners and are grounded with the ratchet gasket. The commonly used ground wire structure for large-screen equipment is three grounds (equipment working ground, power ground, and lightning protection ground) to protect the power supply and signal system from lightning strikes and impulse voltage damage to the equipment.
3. The large outdoor led screen is leak-proof inside and outside.
The mask and box are made of insulating materials. The resistance of the insulating material is greater than 10 megaohms, and the leakage current is less than 1.8MA. After inspection by the headquarters, the product can still withstand 50hz under high temperature and high temperature. The insulation breakdown of the test voltage requires 1500W for 1 minute. The circuit board will be protected by three-proof paint, and the quality of the world's large LED screens should be higher than IP65. So as to ensure the leakage and waterproof performance.
4. Control the humidity of the outdoor large screen.
When the wet full-color screen is powered on, it will cause corrosion of the LED display components and cause damage; therefore, it is necessary to maintain a large-screen full-color LED environment and do not allow any objects with humidity characteristics to enter the large LED screen.
5. Active protection of outdoor led displays.
Prevent possible problems, take active protective measures, try to remove the LED screen of the large screen; when cleaning the screen, try to wipe it lightly to reduce the possibility of damaging the LED display.
6. Outdoor led display to control screen current.
Do not stay on the full white, red, green, and blue screen for a long time when playing, so as to avoid excessive current, overheating of the power cord, damage to the LED light, and affect the life of the LED display. Do not disassemble or splice the screen at will.
7. Use the LED display outside the control room.
It is recommended that the led display screen rest for more than 2 hours a day, at least once a week during the rainy season. Usually the screen is turned on at least once a month, and the screen is on for more than 2 hours.
8. Keep the power supply of the outdoor led display stable.
Maintain a stable power supply, do a good job of grounding protection, and avoid lightning strikes, especially in bad natural conditions, especially during thunderstorms.
9. Prohibit contact with conductive metals such as water and iron powder.
Put the LED display in a low-dust environment as much as possible. Larger dust will affect the display effect, and too much dust will damage the circuit. If water enters for various reasons, please cut off the power immediately until the screen display is dry.
10. Outdoor led display screen is rainproof and waterproof.
The led display adopts modular design and manufacture, all composed of electronic components. Short-circuit leakage can easily cause unnecessary losses. Outdoor LED display must ensure that the equipment meets the relevant waterproof standard IP68: module filling, back brushing, waterproof box, and waterproof rubber ring connected to the box.
