About light and illumination


 

Car park


A car park (32 m x 50 m) with a medium volume of traffic at an office complex or a department store should be illuminated with at least 10 lx in order to allow easy orientation. A reduction of the illumination level to 5 lx is recommended at night. As soon as persons enter the car park, or cars drive in, the degree of illuminance is raised to 10 lx again. Pole-top luminaires with precision reflectors are ideal for illuminating the area. With a pole height of 5 m and luminaire spacing of 21 m, three pole-top luminaires on the two long sides of the car park and three double pole-top luminaires of the same type in the centre of the useful area are sufficient to ensure uniform light distribution and the required degree of illuminance.
