Basic Info
The OSRAM Siteco Roadmax series is designed for complex traffic hubs like large highway interchanges,expressway ramps,and multi-lane roundabouts.Its core goal is to provide high-level,uniform road surface illuminance,reducing driver blind spots and shadows while clearly defining road alignment and curbs,thereby enhancing traffic safety,especially at night and in poor weather.
Customer reviews
Thomas Jensen · Chain Supermarket Property Director
After installing high mast lights in our large parking lot,surveillance footage clarity improved noticeably,strengthening security for vehicles and pedestrians.The even,shadow-free lighting has received positive customer feedback for feeling safer at night.The well-designed pole height and angle effectively prevent light intrusion into surrounding residential buildings.
Michael Brown · Petrochemical Park Safety Director
The explosion-proof high mast lights for oil & gas fully comply with ATEX Zone 2 standards. Their specialized heat dissipation and flameproof joint designs eliminate ignition risk. Internal components remain dry after routine high-pressure washing, and the anti-corrosion coating is intact in the corrosive atmosphere.
Mohammed Ali · Large Logistics Center Operations Manager
The high mast lights in the logistics center parking and aisels are highly reliable.Paired with motion sensors for'light-on-approach,dim-on-departure'operation,energy savings are substantial.The high CRI lighting facilitates nighttime goods sorting and verification.The rugged construction withstands daily impacts with minimal maintenance required.
Product Description
Features
Fixtures use dedicated road lighting optics to precisely direct light onto the road,with strict glare control(Threshold Increment TI must meet standards).Luminaire head layout is calculated to effectively cover multiple lanes and curved areas.Pole design is robust with a stable foundation for strong winds at interchanges.Modern versions fully utilize LEDs for better efficiency and longer maintenance cycles.

Specifications
Illuminance levels,uniformity(Uo),and glare limits must strictly follow road lighting standards like EN 13201 or IESNA RP-8.Poles are often conical or polygonal tapered,with internal ladders or external lowering devices.They support NEMA or Zhaga interfaces for future upgrades.Optional individual fixture monitoring enables fault alerts and energy metering.

Applications
Mainly for urban expressway interchanges,highway service areas/toll plazas,large roundabouts,and long bridges requiring extensive continuous lighting.Lighting aims to help drivers identify road conditions early,judge distances,and spot obstacles,making it a key part of intelligent transport infrastructure.
Frequently Asked Questions (FAQ)
Q:What is the basis for the height and illuminance design of intersection high mast lights?
A:Based on road class,lanes,traffic flow,and safety needs,following standards like CJJ45.Height is typically higher(>20m),with illuminance and uniformity exceeding regular road sections to eliminate blind spots.
Q:How to reduce glare from high mast lights for drivers on intersecting roads?
A:Use cutoff luminaires with precise aiming to keep maximum light intensity outside drivers'sensitive view angles.Strategic pole placement avoids direct luminaire visibility in the forward line of sight.
Q:How to avoid chaotic shadows from multiple poles at complex intersections?
A:Requires professional lighting calculations and simulations to optimize pole placement and beam distribution,ensuring overlapping light from multiple poles for uniform coverage of the entire intersection and crosswalks.
Q:What role do intersection high masts play in supplementing light for surveillance cameras?
A:They provide stable,uniform background light for traffic and security cameras,reducing overexposure from headlights,ensuring clear 24/7 capture of license plates,vehicle types,and behavior.
Q:How to improve visibility under these high masts in inclement weather?
A:Beyond meeting illuminance standards,using higher CRI(Ra>70)sources can help.Good average road surface luminance and uniformity improve overall visibility in rain/fog better than sheer illuminance.
Q:How is smart connectivity applied to intersection high mast management?
A:Can integrate V2X communication units,environmental sensors,and info displays.Enables traffic-flow-based dimming,provides environmental data for autonomous vehicles,or displays traffic guidance messages.
