Light pollution
“Light pollution” or obtrusive light refers to the excessive, misdirected and disturbing artificial light. According to the International Lighting Vocabulary (ILV) the generic term of light pollution is defined as the sum total of all adverse effects of artificial light. This can be found in the form of spill light, disturbance of visual task, discomfort and disability glare, intrusive light, reflected light, colourful and dynamic light, upward directed light and macroscopically as sky glow.
Negative effects have been highlighted for several years with preoccupations on human health, biodiversity preservation, safety for drivers and cyclists, astronomical observations, astro tourism and an obvious impact on global energy consumption.
The legal frameworks of several countries have started to take into account that topic in order to regulate and limit the obtrusive light. For many years, the assessment of the aspects of light pollution is performed by various disciplinary groups. In this challenging situation, a solid metrological basis is required.
