As summer arrives, extended rainy seasons and typhoons significantly impact coastal cities, with heavy rainfall posing higher requirements for lightning and rain protection for outdoor LED displays.
1. Wind and Shock Resistance of Outdoor LED Displays
With the widespread use of outdoor LED displays for advertising, installation methods have become increasingly diverse, including wall-mounted, embedded, ceiling-mounted, rooftop, and pole-mounted installations. To prevent equipment from falling, strict requirements are set for wind resistance, shock resistance, and the selection of steel materials for load-bearing structures, especially for rooftop and pole-mounted installations.
2. Lightning Protection Measures for Outdoor LED Displays
To ensure proper grounding, all metal casings and rear covers of LED display equipment have independent grounding terminals with waterproof connectors and serrated washers for grounding. Common grounding structures include three types: operational grounding, power grounding, and lightning protection grounding. These measures protect the power and signal systems from lightning strikes and surge damage.
3. Internal and External Leak Prevention
The display’s mask and casing are made of insulating materials with a resistance greater than 10 megaohms and a leakage current less than 1.8mA. Products undergo strict testing to ensure they withstand high temperatures and high humidity, passing insulation breakdown tests at 1500W for one minute. Circuit boards are coated with protective conformal coatings, and outdoor LED displays are designed to meet or exceed IP65 standards for waterproofing and electrical safety.
4. Controlling Humidity in Outdoor Displays
Moisture in full-color displays can corrode components and cause damage. Maintaining a dry environment for the display is essential to prevent any moisture-laden materials from entering the interior of the LED screen.
5. Proactive Protection Measures
To prevent potential issues, proactive protection is recommended, such as dismantling the display during extreme conditions. When cleaning, gently wipe the screen to minimize the risk of damage.
6. Controlling Screen Current
Avoid prolonged display of bright screens with all-white, red, green, or blue colors to prevent excessive current, overheating of power cables, and potential damage to LED lights. Do not disassemble or reassemble the display without proper guidance.
7. Operational Guidelines for Outdoor LED Displays
Allow the LED display to rest for at least 2 hours daily. During the rainy season, turn the display on at least once a week, and in other periods, activate it for at least 2 hours monthly to ensure optimal performance.
8. Stabilizing the Power Supply
Maintain a stable power supply with proper grounding to avoid lightning damage. Extra caution is required during harsh weather conditions, particularly thunderstorms.
9. Avoid Contact with Water and Conductive Metals
Keep the LED display screen away from water, iron filings, or conductive materials. Install the display in low-dust environments as excessive dust can degrade performance and damage circuits. In case of water ingress, immediately cut the power and wait until the screen is completely dry before use.
10. Rainproof and Waterproof Measures
Outdoor LED displays consist of modular electronic components, where short circuits and leaks can cause unnecessary losses. Ensure the equipment complies with waterproof standards of IP65 or higher, utilizing waterproof adhesives, back glue, sealed waterproof enclosures, and waterproof gaskets between modules and enclosures.
By following these protective measures, outdoor LED displays can withstand thunderstorms and maintain reliable performance in challenging weather conditions.
