Freedom of design - Free arrangements of the luminares? - bright-/darkzones on the roadsurface? - Which luminare design?

LiDAC, Uwe Rabenstein, April 8, 2009, Basics for roadlighting

3

Freedom of design - The safety for the traffic has abolute priority! - The arrangement of the luminare, spacing and height are results of the official standards. - Using Luminares with a good design is allowed. - Different light colours are possible, but the target is an efficacy lightinstallation.

Glare?

LiDAC, Uwe Rabenstein, April 8, 2009, Basics for roadlighting

15

What is glare? Glare is light in high differences of luminace in the field of view, which is created by luminares. This differences create a physiologicalpsychological effect which has influence to: • Visual comfort • Visual power

LiDAC, Uwe Rabenstein, April 8, 2009, Basics for roadlighting

16

8

Kinds of glare Psychological glare (discomfort) -> create a discomfort and with a influence over a long period, the working capacity is reduced.

Physiological glare (disability glare) -> reduce the visiual power in kind of - visual sharpness - contrast recognization - lower working capacity

LiDAC, Uwe Rabenstein, April 8, 2009, Basics for roadlighting

17

Base for the visibility … is the contrast between difference objects.

Lo − Lu Co = Lu Co Lu Lo

contrast luminance in the surrounding luminance on the object LiDAC, Uwe Rabenstein, April 8, 2009, Basics for roadlighting

Influence from glare for the visibility The contrast will be reduced between the two objects.
