Custom solutions for different highway projects
Every day, highway drivers rely on Variable Message Signs (VMS) to receive important traffic information. Whether it’s a speed limit update, road construction notice, lane closure, or accident warning, the message must remain clear at a long viewing distance and under direct sunlight.
For this reason, DIP LED displays continue to be the preferred solution for many highway traffic projects. Their high brightness, low power consumption, and long-term reliability make them well suited for demanding outdoor environments.
1. Better Visibility for Highway Traffic
On highways, drivers often have only a few seconds to read a message. A display that is difficult to see can reduce reaction time and affect road safety.
Unlike standard SMD LEDs, each DIP LED has its own lens that directs light toward approaching vehicles instead of scattering it in different directions. This focused light improves visibility in strong sunlight and increases contrast, making messages easier to read from a greater distance.
That is why DIP traffic LED displays are still widely used for Variable Message Signs, toll stations, and intelligent transportation systems (ITS).
2. High Brightness with Lower Energy Consumption
High brightness usually means higher electricity costs. However, a well-designed highway LED display should deliver strong brightness without wasting energy.
LEDA Display improves luminous efficiency through optimized circuit design and high-efficiency LED chips, allowing our displays to achieve excellent brightness while maintaining low power consumption.
| Pixel Pitch | Brightness | Typical Power Consumption |
|---|---|---|
| P10 Full Color | 15,400 nits | 112 W/m² |
| P16 Full Color | 12,400 nits | 89 W/m² |
| P20 Full Color | 8,500 nits | 59 W/m² |
For highway projects with multiple display boards, lower power consumption can significantly reduce operating costs over the lifetime of the system. Lower heat generation also helps improve component stability and extend the service life of the display.
3. Double-Sided Waterproof Protection
Outdoor traffic displays operate in challenging environments throughout the year. Rain, humidity, salt spray, dust, and industrial pollution all increase the risk of corrosion and component failure.
Many LED modules are only protected on the front side. At LEDA Display, we use a double-sided waterproof potting process, sealing both the front and back of every module with high-quality waterproof material.
This extra protection helps prevent moisture, dust, and corrosive gases from entering the module, improving long-term reliability while reducing maintenance requirements.
4. Proven Performance in Different Climates
A highway traffic LED display must continue working reliably in very different weather conditions.
Our DIP LED traffic displays have been installed in projects across various climate zones, including:
–China – Stable operation on the Huning Expressway with heavy daily traffic.
–Inner Mongolia – Reliable performance in winter temperatures as low as -40°C.
–Indonesia – Long-term operation in hot, humid, tropical environments with excellent corrosion resistance.
These projects demonstrate the durability of our displays in both freezing and high-humidity conditions.
5. Custom Solutions for Highway Projects
Every highway project has different technical requirements.
LEDA Display offers customized solutions for:
–Pixel pitches including P10, P16, and P20
–Cabinet sizes and structures
–Control systems
–Power supply configurations
