Optical Performance & Brightness

Powered by large-chip DIP510 LEDs with optical lenses, the display achieves brightness up to 20,000 nits (on P25/P31 models) and standard 12,000 nits on P16/P20. This ultra-high contrast ensures speed limits and warnings cut through glare, even when facing the sun directly on wide multi-lane gantries.

Long-Range Penetration (Safety)

Designed as a primary guidance device, the C-Tra-KXB guarantees text legibility at 200m+ (dynamic) and 250m+ (static). Its focused beam angle penetrates fog and rain, giving drivers on high-speed motorways sufficient reaction time to changing road conditions.

Robust Galvanized Structure

Built with a galvanized iron cabinet, this series balances durability with cost-efficiency. Weighing <60 kg/m², it is significantly lighter than legacy cabinets (often >80kg), reducing static load on new gantries while providing the rigidity needed for typhoon-prone coastal areas.
chipshow

Harsh Environment Protection

The system features fully sealed IP65 modules, protecting internal components from dust, driving rain, and corrosive exhaust fumes. With an operating range of −20°C to +50°C, it performs reliably in environments ranging from freezing northern bridges to scorching desert highways.

Energy Efficient Drive

Despite its high brightness, the optical lens technology focuses light only where needed (the road), reducing wasted light spill. Combined with an energy-saving drive IC, it maintains lower average power consumption than traditional wide-angle DIP screens, lowering long-term OpEx.

Installation & Integration

Standard cabinet formats (1024×1024 mm / 1280×1280 mm) allow for modular assembly of full-span gantry signs. The system supports standard HUB75 and mainstream controllers (Chipshow/Nova), ensuring seamless integration into existing Traffic Management Centers (TMC) and ITS networks.

How does the gantry VMS perform in regions with extreme sunlight or heavy fog, like the Middle East or coastal highways?
In areas prone to intense desert glare or dense coastal fog, exceptional visibility is critical for road safety. This variable message sign (VMS) utilizes advanced DIP510 optical lens technology, delivering an ultra-high brightness of up to 20,000 nits. This ensures traffic messages remain clearly readable from over 250 meters away. Additionally, it strictly complies with the EN12966 optical class standards, providing high contrast without causing dangerous glare to drivers, regardless of extreme weather conditions.
