Starlight Road LED Variable Speed Limit Sign: Empowering Dynamic Traffic Control with Precision Technology

In the realm of expressway and national highway management, dynamic speed limits have emerged as a crucial strategy for enhancing traffic efficiency and safety. Starlight Road's LED Variable Speed Limit Sign offers an advanced solution for intelligent road management, combining high-brightness displays, smart controls, and robust environmental adaptability.

Constructed with high-quality cold-rolled steel and a durable spray-painted finish, the sign is available in two sizes (1.2x1.2m and 1.5x1.5m) to suit various road conditions. With an IP65 rating and wind resistance of ≥150 km/h, it operates seamlessly in extreme temperatures ranging from -30°C to +70°C. The display unit features P31.25 specifications, a 750x500mm screen with a 24x16 pixel matrix. Its yellow LEDs, boasting ≥8000 cd/m² brightness and 590-596nm wavelength, ensure clear visibility from 300 meters away, complemented by a ≥30° viewing angle. The outer red pixel tubes, with individual LEDs emitting ≥3500 cd/m², create a highly visible warning effect.

Technologically, the sign supports a wide voltage input of AC220V±15%, consumes ≤200W power, and utilizes a static constant current drive for an 80,000+ hour lifespan. Dual communication interfaces (RS485 & RJ45) enable both local and remote operation, allowing administrators to adjust speed limits in real-time (ranging from 60-120 km/h) and modify brightness based on weather and traffic conditions (up to 12,000 cd), optimizing energy usage without sacrificing visibility.

This sign is ideal for high-risk areas like expressway tunnel entrances, sharp curves, and national highway speed transition zones. For instance, during rainy or foggy conditions, remote control can reduce the speed limit from 120 km/h to 80 km/h, while at interchange hubs, dynamic limits guide vehicles safely.
