Industrial park street-light spacing cannot be set by one fixed ratio. Road width, pole height, outreach, optics, layout, pavement and target uniformity all affect spacing.
Installation planning should also cover foundations, cables, grounding, surge protection, access doors, controls and maintenance.
Define road and layout geometry
Record road width, lanes, footpaths, intersections, curves, parking and gates before selecting single, staggered or opposite layouts.
- Separate main and branch roads
- Map trees and buildings
- Confirm CCTV and pedestrian needs
Check spacing with height, optics and uniformity
Different optics and road widths produce different spacing even at the same pole height.
- Do not use average lux alone
- Check darkest points and longitudinal uniformity
- Control glare
Include foundations and electrical work
Poles, flanges, foundations, conduits, power, grounding and surge protection must be coordinated.
- Confirm soil and foundation
- Reserve cable and access space
- Protect outdoor connections
- Check solar orientation
Commission and accept
Verify pole alignment, aiming, measured power, road grid and control schedules.
- Number poles and circuits
- Use late-night dimming
- Record lux and faults
