Parking lots - Excellent lighting conditions for excellent visibility
The illumination of parking lots is influenced by different functions and requirements. In some parking spaces and areas, motorized traffic comes face to face with pedestrians and cyclists. The functional lighting concept must therefore regard the parking space as traffic space and attach greater importance to safety. Good lighting presents traffic more clearly and reduces the risk of accident. Selected lighting solutions promote better overall orientation and allow vehicles to be identified more quickly. They also help to identify boundaries and obstacles well in advance.
Traffic areas require stronger lighting than parking areas. A medium lighting strength with good glare reduction and even distribution right to the fringes is required, depending on the traffic frequency. Luminaires are positioned in line with the parking spaces and take into account hazardous areas such as entrances and exits.
Other requirements may result from the position and design of the parking lot. Particularly small parking lots in inner city areas are often confusing and therefore potentially hazardous due to the surrounding greenery and structural environment. A high light quality with a balance of horizontal and vertical lighting strengths is particularly important here.
Large parking lots away from buildings and zones with flowing traffic are very efficient to illuminate due to the height and wide spacing between the different light points. Lower light point heights are recommended for parking lots located directly next to areas where glare must be minimized.
Secondary reflector systems offer another alternative for illuminating large parking lots. These systems can project the light extremely precisely and evenly onto a specific surface. The concentrated light from powerful floodlights is diverted to a mirror that splits the light into a series of small light points and casts it back onto the ground. A single secondary reflector system can illuminate surfaces of up to 10,000 square meters efficiently and evenly.
