Light Pollution in Ultraviolet and Visible Spectrum: Effect on Different Visual Perceptions

摘要: In general terms, lighting research has been focused in the development of artificial light with purpose saving energy and having more durable lamps. However, consequences that night could bring to human being living organisms have become an important issue recently. Light pollution represents a significant problem both environment health causing disruption biological rhythms related not only visible spectrum, but also other parts electromagnetic spectrum. Since lamps emit across wide range all photobiological species may be exposed another type pollution. By comparing five different lamps, present study attempts evaluate UV radiative fluxes relative what humans two insects perceive as sky glow level. We analyzed three atmospheric situations: clear sky, overcast evolving precipitable water content. One finding suggests when constant illuminance urban spaces guaranteed from low pressure sodium most effect visual perception tested. But fixed number luminaires situation changes lamp would best choice for species. The effects can interpreted correctly if types required amount scotopic luxes at ground are taken into account simultaneously. If these factors combined properly, then ecological partly reduced. results this equally useful engineers, architects, biologists researchers who studying on biodiversity.
