Several studies confirm that artificial lighting at
night disrupts the natural light/dark cycle and
interferes with nature and humans' natural
patterns with detrimental consequences for our
physiology, behaviour and health. Still, artificial
light levels are increasing globally, and light
pollution is not considered a "rightful" form of
pollution.
This thesis investigates how outdoor lighting can
support the coexistence of human and nature in
urban green areas by minimizing the impact on
biological patterns of nature and human,
enabling human eye adaption, and enhancing the
feeling of reassurance.
Through a comprehensive literature review and
exploratory test on contrast perception and
colour reflectance, a design framework is
proposed focusing on three lighting
characteristic: 1 quantity and intensity, 2
direction and distribution and 3 spectrum and
colour, that has the potential of being very either
harmful if used without consideration or useful if
used wisely.
