Study of Light Pollution in Urban Lighting in Nisantasi Example

Abstract

To make urban identity-forming components visible by making use of technologic improvements, and to make the city livable for everybody by enhancing aesthetic and charming attraction are becoming important for urban designers. Lighting is becoming an important factor to suit cities to livable places for livings in all comfort conditions. By the improvement of science and technology, to organize the life spaces of livings according to today’s comfort conditions are considered more and more important. Urban lighting is affecting both the lighting comfort and livings’ (humans, animal, and plants) health in many dimensions. The light used on the unsuitable spot, unsuitable direction, unsuitable amount and unsuitable time is defined as light pollution. Within the scope of this study, national and international literature research related to urban lighting is done and basing criteria are identified. In the frame of these identified criteria, Nisantasi example is examined in the context of lighting pollution. Important streets and lanes and important historical and religious structures that gained a seat in public memory are identified. Designing criteria of the lighting tools existing in these identified areas and their suitability according to their spot are evaluated and measuring their illuminance sufficiency, the issues which are detected as light pollution are stated. In conclusion, the studies done in our country are cited and the issues that are to be done to prevent light pollution are introduced as a suggestion.

Light Pollution and Smart Outdoor Lighting

“…The basis of the lighting concept is considered to be light; however, the aim of lighting is to visualize the illuminated environment with a light source [44]. Urban lighting affects both the comfort of lighting and the health of living creatures (human, animal and plants) in many dimensions [3]. The wrong selection and misdirection of the fixtures and lamps used to cause light trespass, glare, vertical light and excessive light in outdoor lighting [42].…”

“…Systems like unnecessary store lighting, inefficient or low-intensity street lighting fixtures, illuminated billboards that abruptly change intensity and colour to attract people, etc. that do not allow homogeneous light distribution are a part of light pollution and create visual pollution both in terms of visual health and comfort and aesthetics [3,50]. In general, sources of light pollution can be listed as follows:…”

“…There should be a benchmark and a standard in lighting [3]. Today, many countries are making legal regulations to limit light pollution.…”

“…Lighting has become an essential factor in making cities suitable for livable spaces to live in all comfort conditions [3]. Proper lighting is crucial in economic, environmental and social aspects.…”
