Super typhoon "Huajiasha" recently swept through South China, severely testing coastal cities.
As a key carrier for outdoor advertising and information dissemination, the safety of LED displays cannot be ignored after experiencing the continuous impact of strong winds, heavy rain, and lightning. A systematic safety inspection guide is crucial to help identify hidden dangers in time and avoid potential economic losses and safety accidents.
Typhoons are extremely destructive natural disasters. The strong winds, heavy rain, and lightning they bring can affect outdoor LED displays in multiple ways. Strong winds may cause the steel structure to loosen or even detach, heavy rain may seep inside and cause short circuits, and lightning can destroy the control system.
Even if the display appears to be operating normally now, potential damage may manifest gradually over the coming weeks. For example, internal moisture accumulation can lead to slow corrosion of components, and minor structural loosening could worsen during the next strong wind. Therefore, a timely and comprehensive inspection after the typhoon is essential.
The stability of the steel structure is the priority. After Typhoon "Huajiasha", focus on inspecting:
Basic Support Structure: Check the display's steel structure for obvious deformation, fractures, or looseness. Pay special attention to welding points and bolts at connections for signs of corrosion or loosening.
Surface Coating Condition: Check if the anti-corrosion paint on the steel structure is intact. Repair any peeling promptly to prevent corrosion from spreading.
Tip: Gently tap the steel structure with a small hammer. A clear sound indicates normality, while a dull sound might suggest internal problems like corrosion or cracks.
The heavy rain brought by the typhoon is a severe test of the LED display's waterproof capability:
Enclosure Seal Check: Inspect the waterproof gaskets at the enclosure seams for aging or deformation, and check if the sealant is cracked.
Module Status Assessment: Check the module surface for water stains, droplets, and the backplane for signs of water ingress.
Drainage System Unobstructed: Ensure the drainage system around the display is clear and there is no water accumulation.
Emergency Treatment: If minor water ingress is found, cut off the power immediately and dry thoroughly with a blow dryer on a low setting before reapplying power for testing.
Electrical safety is directly related to fire risk and requires extra attention:
Power Line Check: Check connections in the distribution box for rust or looseness. Ensure the box is properly grounded. Inspect power cords for wear or breakage.
Lightning Protection Device Verification: Regularly inspect lightning rods and grounding lines. Test the facilities after thunderstorms; replace if damaged.
Component Status Assessment: Check power supplies, control cards, etc., for burn marks, abnormal heat, or noise.
Safety First: All electrical inspections must be performed with the power completely off. Use a professional electrician if necessary.
After completing structural, waterproof, and electrical checks, proceed with power-on testing:
Pixel-by-Pixel Check: Look for dead pixels, always-on pixels, or dim pixels. Check if colors display normally.
Control System Verification: Check if the control system operates normally and signal transmission is stable.
Brightness Adjustment Test: Test if the automatic brightness adjustment function works correctly, ensuring clear visibility under different ambient light conditions.
For displays damaged in the typhoon, different handling schemes apply based on the extent of damage:
Minor Damage (slight water ingress, individual module failure): Localized repair is possible, replacing damaged modules or components.
Moderate Damage (steel structure deformation, multiple module damage): Requires assessment by professional technical personnel. Partial reconstruction might be necessary.
Severe Damage (main structure damage, large-scale failure): It is advisable to contact the original manufacturer or a professional organization for a comprehensive assessment to decide between repair or replacement.
To cope with potential extreme weather in the future, choosing LED displays suitable for outdoor environments is crucial. Kingaurora's A Pro Series and B Pro Series outdoor LED displays are designed from the outset considering various harsh weather conditions, featuring high protection ratings and robust structural designs.
Utilizes exclusive DIP570 three-in-one lamp bead technology and boasts an IP65 high protection rating, effectively resisting rain, dust, and extreme temperature erosion, ensuring stable operation under adverse climatic conditions. Its high brightness of 8000-10000 nits guarantees clear visibility even under direct sunlight, while its energy-saving technology can save up to 30% electricity compared to similar products.
Features an ultra-thin, lightweight design with a high light transmittance of 62%. This design not only reduces the screen's weight but also effectively lowers wind resistance, offering excellent wind resistance, making it very suitable for typhoon-prone areas. Its modular design supports both front and rear maintenance, significantly reducing later maintenance difficulty and costs.
The typhoon season poses severe tests for outdoor LED displays. Only by implementing adequate preparation in advance and systematic periodic inspections can a solid safety defense be built, ensuring the screens operate stably and remain safe and sound amidst fierce winds, heavy rains, thunder, and lightning.
