A parking garage light is a pendant or surface mounted light fixture that provides ambient lighting to facilitate the safe movement of both vehicular and pedestrian traffic in a parking structure or parking bay. A parking garage is an above-ground or underground facility that consists of one or more platforms with internal sloped floors or external ramps providing vertical vehicle circulation. The above ground facility, which is at least partially enclosed, often requires supplemental daytime illuminance, whereas underground garages require full day and night lighting.
Parking facility lighting faces the challenge from the mixed traffic within a confined garage space where visual obstacles or distractions such as structural columns, pipe boards, guard rails, pavement markings, shadows between vehicles and structures, and changes in surface elevation are often present. Parking facility lighting also needs to survive demanding environmental conditions. In addition to the corrosiveness associated with high levels of exhaust fumes and humidity, above-ground parking garages expose light fixtures to an outdoor environment as these facilities are partially open to provide natural ventilation.
