Why this application needs its own lighting approach
Roadway lighting must support drivers, cyclists and pedestrians by revealing lane geometry, obstacles and conflict points while controlling glare and light outside the road corridor.
Street, Parking & Public Area Lighting
Street & Roadway Lighting
Roadway lighting must support drivers, cyclists and pedestrians by revealing lane geometry, obstacles and conflict points while controlling glare and light outside the road corridor.
ApplicationProject-specific engineering
MountingVerify actual geometry
ControlsZone / dim / schedule as needed
SelectionPhotometric calculation
required
Understand the site
Start with the actual geometry and operating task.
Road width, lane count, median, shoulder, curvature, intersection spacing, pole setback and mounting height determine the optical distribution. The design should follow the actual carriageway rather than use a generic pole spacing.
Key project inputs
Send road width, lane count, pole spacing / height, outreach, intersection details and target road class.
Layout & mounting
Use the real site first, then validate the layout.
Single-sided, staggered, opposite or median-mounted layouts can be used depending on road width and classification. Pole outreach and luminaire tilt should keep the principal beam on the roadway.
Road width, lane count, median, shoulder, curvature, intersection spacing, pole setback and mounting height determine the optical distribution. The design should follow the actual carriageway rather than use a generic pole spacing.
Use this only as a visual reference for mounting and coverage logic. The final design must follow the real project.
Typical reference only. Final mounting positions, pole or fixture quantity, beam
distribution, aiming, controls and structural loading should be confirmed by photometric
calculation and the applicable project requirements.
Lighting performance
What the completed installation must achieve.
Review road luminance / illuminance, longitudinal uniformity, overall uniformity, threshold effects, glare and visibility at junctions or crossings.
Primary visual taskReview road luminance / illuminance,
longitudinal uniformity, overall uniformity, threshold effects, glare and visibility at
junctions or crossings.
Glare / off-site impactReview visible source brightness, observer
positions and light outside the intended work or traffic area.
Uniformity / transitionsAvoid isolated hotspots and abrupt
changes between adjacent operating zones.
Vertical visibilityCheck people, equipment, vehicles, racks,
façades or structures where recognition is part of the task.
Environmental reliabilityConsider property-line spill, dark-sky
requirements, trees, utility lines, pole collision risk and maintenance access.
CommissioningVerify installed aiming, controls, operating scenes
and critical measurement points after installation.
Controls & operation
Design the operating scenes before wiring is finalized.
Photocell, astronomical scheduling, network dimming and traffic-based profiles can reduce output during low-demand periods where local policy allows.
ZoningGroup luminaires by real operating areas rather than
arbitrary circuit boundaries.
DimmingUse reduced-output scenes where the task and local
requirements allow.
SchedulingMatch lighting operation to shifts, traffic,
occupancy or curfew periods.
InterfacesSelect 0-10V, DALI, DMX, photocell, sensor or
network interfaces only where compatible with the project architecture.
Accessories, environment & maintenance
Reliability depends on more than the LED package.
Consider property-line spill, dark-sky requirements, trees, utility lines, pole collision risk and maintenance access.
Special project checks
Consider property-line spill, dark-sky requirements, trees, utility lines, pole collision risk and maintenance access.
New build vs retrofit
When reusing poles, verify spacing, outreach, mounting height and old wiring. LED optics can often improve distribution, but poor legacy spacing may still limit performance.

Common questions
Before finalizing the application design.
These answers are general engineering guidance. Project-specific requirements should always take priority.
How should the lighting layout for street & roadway lighting be determined?
Start from the real geometry, mounting positions, operating zones and target visual tasks. Pole or fixture quantity should then be confirmed by photometric calculation rather than copied from a generic example.
Can existing poles, brackets or mounting points be reused?
Often yes, but structural condition, wind / vibration loading, spacing, electrical condition and compatibility with the new optical strategy should be checked first.
Should controls be specified at the same time as the luminaires?
Yes. Zoning, dimming, sensors and schedules affect driver selection, wiring and commissioning. Controls should fit the site operating policy and maintenance capability.
What information is most useful for an initial proposal?
A site or floor plan, mounting height, existing fixture information, target performance, operating hours, environmental conditions and clear photos of the installation area.
Are the typical layouts shown on this page fixed designs?
No. They are engineering references only. Final mounting positions, fixture quantities, beam distributions and aiming angles should be verified for the actual project.
