Tunnel lighting is not like ordinary lighting. It must combat the “black hole effect” at entrances, eliminate glare at exits, withstand constant vibration and humidity, and operate reliably 24/7. The OrbitLine Series LED Tunnel Light from Mason was engineered to meet these challenges head-on.

With power options from 50W to 240W, a rugged magnesium-aluminum-copper alloy body, and advanced intelligent control, OrbitLine delivers uniform, glare-free illumination while cutting energy waste. Whether you are lighting a highway tunnel, an urban underpass, or a pedestrian passage, OrbitLine is the dependable choice.

Why OrbitLine Stands Out in Tunnel Lighting?

Robust Construction for Harsh Environments

OrbitLine is built with a quenched magnesium-aluminum-copper alloy that offers high strength and fast thermal conductivity. The aerodynamic system design ensures excellent heat dissipation, while the thermal-electrical separation design keeps temperatures low and extends luminaire lifespan.

• Structural waterproof design – easier maintenance, IP65 rated
• 4mm ultra-clear tempered glass – improves IK rating and light transmission
• Built-in PET high-reflectivity film – boosts optical efficiency
• External 32mm power supply bracket channel – clean, organized installation

 

Advanced Optical Design – No Glare, No Compromise

Tunnel lighting must be bright but not blinding. OrbitLine features a dedicated secondary optical design that enhances anti-glare performance. It supports multiple configurations:

• Direct lighting or diffuse reflection lighting
• 5050 small square lenses
• Optional diffuser plate
• Anti-glare shield
• Beam angles: 30°, 60°, 90°, 120°, and 80°×150°

This flexibility allows engineers to tailor light distribution precisely to tunnel geometry and traffic flow.

Flexible Installation & Custom Lengths

The mounting bracket is adjustable up to 180 degrees and includes a secondary anti-rotation solution for stable aiming. Luminaire length can be customized according to construction site requirements, making OrbitLine suitable for a wide range of engineering projects.

Intelligent Control System – Lighting That Thinks

OrbitLine is not just a luminaire; it is part of a complete smart lighting ecosystem. The intelligent control system dynamically adjusts lighting based on:

• Outside tunnel luminance
• Real-time traffic flow
• Vehicle speed

This on-demand lighting approach delivers three key benefits:

• Driving Safety – Addresses the “black hole effect” at entrances and “glare” issues at exits, ensuring smooth visual adaptation for drivers.
• Energy Efficiency & Emission Reduction – Reduces energy waste, delivering both economic and social benefits.
• Management Efficiency – Internet + Lighting enables centralized monitoring and intelligent control.

 

Two Dimming Schemes to Suit Your Project

Loop Dimming Scheme (0-10V Bus)

The lighting main control cabinet outputs multi-channel 0-10V bus signals. Luminaires are divided into entrance enhancement, transition, basic, and exit enhancement zones, each operating independently. This is the lowest-cost solution among all dimming methods meeting the same requirements.

Single-Lamp RS-485 Bus Dimming

The most widely used single-lamp solution. It monitors each luminaire’s status, electrical parameters, and fault conditions for refined management. It also enables smooth transitions inside the tunnel rather than stepped changes.

Where Is OrbitLine Used?

OrbitLine is primarily designed for:

• Highway tunnels
• Urban underpasses
• Pedestrian passages
• Channel tunnels under cities

Its modular expandable design also makes it suitable for other linear lighting applications requiring high protection and intelligent control.
