A light standard is the pole, with its base and arm, that supports one or more luminaires above a parking lot, roadway or structure top deck. The term is common in specifications; most people simply call it a light pole.
Pole height and spacing set how evenly light falls across the lot. Taller poles spread light farther with fewer foundations but can increase spill onto neighbors; shorter poles cost less individually but require more of them.
Design considerations
- Mounting height and spacing. Chosen together with the luminaire optics to meet illuminance and uniformity targets.
- Location. In islands or at stall corners where they do not block parking or access aisles.
- Foundations and bases. Concrete bases raised above the pavement to protect against vehicle impact and corrosion.
- Wind and structure. Poles and their anchorage are designed for wind loads, including fixtures and banners. On top decks, the structure must carry the base loads. See wind loads.
- Light control. Cutoff luminaires and shields to limit light trespass and light pollution.
The Parkonomics view
The pole decides where light can go before the fixture is ever chosen. Lay out poles with parking geometry, not after it.
