Requirements and precautions for outdoor traffic LED display on highways

 

 

 

 

As an important component of intelligent transportation systems, highway outdoor traffic LED displays have more stringent requirements and precautions compared to general outdoor LED displays.

 

I. Technical Requirements

Brightness and Clarity:
According to GB/T 23828 standards, the full-screen white balance brightness of highway LED variable information signs must be no less than 8000cd/m², ensuring clear visibility even under intense sunlight.
The pixel pitch should be adjusted based on the design brightness to ensure clear visibility in different environments.

 

Viewing Angle:
Information readability should be ensured from different angles, typically with a horizontal viewing angle of no less than 30° and a vertical viewing angle of no less than 15°, to meet the needs of drivers viewing from various positions.

 

Protection Level:
It must have a high level of protection, such as IP65 or higher, to adapt to complex outdoor environmental conditions like rain and dust.

Energy Efficiency and Environmental Protection:
The measured energy efficiency value should meet specific energy efficiency standards, reducing energy consumption and environmental pollution.

 

Environmental Adaptability:
It should be able to adapt to outdoor environmental changes, including temperature variations, humidity, and wind speed, ensuring stable operation under various weather conditions.

 

Software and Control System:
The control system should be stable and reliable, with remote monitoring and maintenance functions to facilitate real-time information updates and fault handling.
Regular updates to the software are necessary to utilize the latest features and security patches.

 

 

II. Installation Requirements

Installation Location:
The installation location of the LED screen should comply with road sign hanging requirements, avoiding obstructions and ensuring installation at the specified height to guarantee information visibility.
Factors such as sightline, viewing distance, and ambient light should be considered to ensure drivers can clearly see the information on the display.

 

Structural Design:
The support structure must be sturdy, capable of bearing the weight of the display screen as well as the maximum local wind force.
Structural mechanics calculations should be conducted to ensure safety.

 

Electrical Safety:
A stable and reliable power supply should be chosen to ensure power stability and safety.
Wiring should comply with electrical safety standards to avoid issues like short circuits and electric leakage.

 

 

III. Maintenance and Precautions

Regular Maintenance and Cleaning:
The LED screen should be regularly maintained and cleaned to maintain its performance and extend its service life.
When cleaning, professional cleaning solutions should be used to gently wipe the screen, avoiding direct water spray.

 

Heat Dissipation and Ventilation:
An effective heat dissipation system, such as fans and heat sinks, should be designed to prevent component damage caused by overheating.
Good airflow should be ensured to aid in heat dissipation and extend the service life of the display.

 

Fault Handling:
In the case of a fault, a prompt response and repair should be carried out to minimize the impact on traffic flow.
Sufficient spare parts and professional repair tools should be prepared for quick fault repair.

 

Anti-theft Measures:
When installing in public places, anti-theft measures such as installing surveillance cameras and using anti-theft bolts should be considered.

 

Compliance:
The installation and use should comply with local laws and regulations, including those related to advertising, building safety, and electrical safety.
