Typical Ranges and the Design Factors That Decide"},"content":{"rendered":"

Street-light mounting height commonly ranges from roughly 6\u201315 metres (about 20\u201350 feet), with lower poles often used on pedestrian or residential streets and taller poles on wider, faster roads. That is a planning range, not a design rule. Road width and classification, luminaire photometry, pole spacing and arrangement, target luminance or illuminance, uniformity, glare, conflict areas, maintenance, utilities, structure, wind and the governing authority determine the actual height.<\/strong><\/p>

Pole height, mounting height and luminaire height are sometimes used as if identical. The useful lighting dimension is generally the luminaire\u2019s photometric centre above the relevant road or ground plane. A bracket can raise or lower that point, and a pole on a verge above or below the carriageway changes the relationship. Draw the road cross-section and state the reference datum. Measurements inferred from a photograph are unreliable because perspective conceals elevation and setback.<\/p>

Typical context by road type<\/h2>

Pedestrian-focused streets and local residential roads often favor lower-scale mounting to support the public realm, while collectors and arterials may use greater mounting heights to cover wider pavements and increase spacing. Intersections, crossings, curves, tunnels and transit stops can require different treatment from the adjoining segment. Solar street lights also need panel access to sunlight and a structural review of added wind area; there is no single \u201cbest\u201d height simply because the luminaire is solar-powered.<\/p>

Photometry determines whether height works<\/h2>

Raising a luminaire generally spreads light over a larger area but changes intensity, uniformity, glare angles and vertical illumination. The distribution type, lumen output, tilt, setback, overhang and spacing must be modeled together. A design should evaluate maintained\u2014not initial\u2014performance, including dirt and lumen depreciation. Average illuminance alone can hide dark areas and disability glare. Use current photometric files for the exact luminaire and verify the calculation grid and design criteria.<\/p>

Structural and site constraints<\/h2>

Pole material, shaft geometry, base, anchor bolts, bracket, luminaire mass, projected area, wind region, terrain and attachments form one structural system. Overhead and underground utilities, clear zones, sidewalks, trees, drainage, driveways and maintenance access affect location and height. Do not extend a pole or add solar panels, cameras, banners or antennas without checking the complete structural rating. The local road authority and utility coordination process control the final placement.<\/p>

Begin with the authority\u2019s road classification and lighting criteria, then map cross-section, lane and footway widths, setbacks, conflicts and obstructions. Test plausible mounting heights and spacing in a photometric model using the exact fixture file. Compare maintained values, uniformity, glare and vertical visibility. Coordinate structure and electrical supply, review spill light at properties and ecology-sensitive areas, and retain the calculation assumptions. A rule-of-thumb ratio can screen options but cannot approve a design.<\/p>

Field verification after installation<\/h2>

Confirm installed pole location, verticality, bracket, mounting height, tilt, orientation, control settings and supply. Conduct nighttime observations under agreed conditions and measure required points with calibrated equipment when the specification calls for it. Look for dark bands, excessive glare, tree shadow, reflections, unintended property spill and conflicts with signs. Document deviations and update the asset record so maintenance crews replace a luminaire with the same approved optics and settings.<\/p>

Comment utiliser ce guide de mani\u00e8re responsable<\/h2>

Ce guide explique un processus de d\u00e9cision et ne remplace pas le manuel du produit actuel, un diagnostic professionnel, une approbation technique, des soins m\u00e9dicaux ou les exigences l\u00e9gales locales. Les r\u00e9sultats de recherche r\u00e9duisent souvent une d\u00e9cision complexe \u00e0 une seule r\u00e9ponse. Une conclusion s\u00fbre n\u00e9cessite l'\u00e9quipement ou le sympt\u00f4me exact, le contexte d'exploitation, la juridiction applicable et des preuves v\u00e9rifiables. Conservez ensemble les num\u00e9ros de mod\u00e8le, les photographies, les mesures, les dates et les instructions afin qu'une autre personne qualifi\u00e9e puisse reproduire la d\u00e9cision.<\/p>

Commencez par l'observation pr\u00e9sentant le risque le plus faible. Ne d\u00e9sactivez pas les protections, les inter verrouillages, les dispositifs de protection ou les avertissements pour obtenir une mesure. Si la t\u00e2che implique de l'\u00e9nergie, du gaz, des charges structurelles, des \u00e9quipements en mouvement, une vision alt\u00e9r\u00e9e ou la s\u00e9curit\u00e9 publique, arr\u00eatez-vous lorsque les conditions d\u00e9passent vos comp\u00e9tences. La bonne escalade fait partie d'une d\u00e9marche de diagnostic r\u00e9ussie, et non d'un \u00e9chec \u00e0 terminer le travail.<\/p>\n
