RETHINKING HOW WE LIGHT AT NIGHT: CUTTING LIGHT POLLUTION FOR MORE SUSTAINABLE NIGHTS

Journal of Green Building, 2012
INTRODUCTION Nighttime lighting is an essential part of modern society, yet all too often inefficient practices are employed that lead to poor visibility, energy waste, and light pollution. The use of dark-sky friendly lighting fixtures and techniques can improve the lit environment to be less harsh and more uniform, reduce many of the problems

Optical Sky Brightness at Cerro Tololo Inter-American Observatory from 1992 to 2006

, 2007
We present optical UBVRI sky brightness measures from 1992 through 2006. The data are based on CCD imagery obtained with the CTIO 0.9-m, 1.3-m, and 1.5-m telescopes.

Light-at-night exposure affects brain development through pineal allopregnanolone-dependent mechanisms

eLife, 2019
The molecular mechanisms by which environmental light conditions affect cerebellar development are incompletely understood. We showed that circadian disruption by light-at-night induced Purkinje cell death through pineal allopregnanolone (ALLO) activity ...

Alleviate light pollution by recognizing urban night-time light control area based on computer vision techniques and remote sensing imagery

Ecological Indicators
Light pollution caused by unreasonable and excessive use of outdoor artificial light at night (ALAN) has become one of the fastest growing and most urgent global environmental problems. Therefore, the International Dark-Sky Association advocated the more

Impacts of duration and intensity of artificial light at night on life history, mating, food consumption, and chemical surface profiles of a leaf beetle species

Basic and Applied Ecology
Artificial light at night (ALAN) is a global change factor of rapidly growing importance. It has been linked to various changes in species physiology, behaviour, communication, and life history. While most studies compared absence vs.

Session 21.2 – Measurement of Light at Night [PDF]

Proceedings of the International Astronomical Union, 2015
AbstractThe introduction of the mercury vapor lamp for general lighting in the 1930s probably marked the beginning of significant light pollution. Lighting levels have increased slowly, year-to-year, with sky brightness levels increasing only slowly on timescales of a year; no measurement protocols or instruments existed to quantify this increase ...

Dreamy Dwellings: How the Sleep Environment Affects Sleep Health in Adults—A Narrative Review

Lifestyle Medicine
Sufficient high‐quality, well‐timed sleep is essential to health and physical, cognitive and emotional functions. Historically, environmental factors such as threats from other beings have likely constrained sleep.

Pomiary zanieczyszczenia świetlnego w warunkach Republiki Czeskiej [PDF]

, 2011
Obtrusive light (light pollution) refers to both the night sky luminance as well as any light that radiates to the places where it is not required. Moreover, this kind of light increases the energy losses.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal [PDF]

, 2016
Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view ...
