Effective Strategies for Protecting Outdoor LED Displays in Harsh Environments

Outdoor LED display screens face harsh environmental conditions such as high temperatures, typhoons, heavy rain, and lightning. To protect the screens in such conditions, several preventive measures need to be taken:

1. Heat Prevention:

Outdoor LED screens are large and consume significant power, leading to heat generation. Proper heat dissipation is crucial to prevent circuit board overheating and short circuits. Designing the screen with good ventilation and installing additional cooling equipment like air conditioners or fans can help manage heat effectively.

2. Typhoon Protection:

Depending on the installation method (wall-mounted, embedded, pillar-mounted, hanging), strict structural requirements are necessary to prevent screen detachment during typhoons. Installers must adhere to anti-typhoon standards and ensure the screen's structural integrity to prevent accidents.

3. Rain Protection:

Outdoor LED screens must have a high waterproof protection level (IP65) to withstand rain. Modules should be sealed with glue, housed in waterproof cabinets, and connected with waterproof seals to prevent water damage.

4. Lightning Protection:

- Direct Strike Protection: Install lightning rods on or near the steel structure of outdoor LED screens if they are not within the protection range of tall buildings.

- Induction Protection: Implement 1-2 level power surge protection for the power system, add signal surge protectors to the signal lines, and install 3-level surge protection for the power system in the equipment room.

- Shield all LED screen cables (power and signal) and bury them underground.

- Ensure proper grounding systems for the screen and equipment room to meet system requirements, with front-end grounding resistance below or equal to 4 ohms and equipment room grounding resistance below or equal to 1 ohm.
