Title Sky glow and outdoor lighting trends since 1976 at the Lowell Observatory Type Journal Article
Year 1990 Publication Publications of the Astronomical Society of the Pacific Abbreviated Journal PASP
Volume 102 Issue Pages 481
Keywords Skyglow; Lighting
Abstract Urban sky-glow (light pollution) trends, recorded photoelectrically in intermediate-band b (472 nm) and y (551 nm) filters at the original site of the Lowell Observatory on Mars Hill near downtown Flagstaff, Arizona, reflect not just the population growth of the surrounding city but also some ameliorating effects of lighting controls and a changing mix of outdoor lighting sources. Since 1976 the sky brightness increased in b but has been virtually constant in y. New ordinances limit lighting growth near observatories and require monochromatic low-pressure sodium luminaires for most applications.

Abstract BACKGROUND: Night shift work, exposure to light at night (ALAN) and circadian disruption may increase the risk of hormone-dependent cancers. OBJECTIVES: We evaluated the association of exposure to ALAN during sleeping time with breast and prostate cancer in a population based multicase-control study (MCC-Spain), among subjects who had never worked at night. We evaluated chronotype, a characteristic that may relate to adaptation to light at night. METHODS: We enrolled 1,219 breast cancer cases, 1,385 female controls, 623 prostate cancer cases, and 879 male controls from 11 Spanish regions in 2008-2013. Indoor ALAN information was obtained through questionnaires. Outdoor ALAN was analyzed using images from the International Space Station (ISS) available for Barcelona and Madrid for 2012-2013, including data of remotely sensed upward light intensity and blue light spectrum information for each geocoded longest residence of each MCC-Spain subject. RESULTS: Among Barcelona and Madrid participants with information on both indoor and outdoor ALAN, exposure to outdoor ALAN in the blue light spectrum was associated with breast cancer [adjusted odds ratio (OR) for highest vs. lowest tertile, OR=1.47; 95% CI: 1.00, 2.17] and prostate cancer (OR=2.05; 95% CI: 1.38, 3.03). In contrast, those exposed to the highest versus lowest intensity of outdoor ALAN were more likely to be controls than cases, particularly for prostate cancer. Compared with those who reported sleeping in total darkness, men who slept in “quite illuminated” bedrooms had a higher risk of prostate cancer (OR=2.79; 95% CI: 1.55, 5.04), whereas women had a slightly lower risk of breast cancer (OR=0.77; 95% CI: 0.39, 1.51). CONCLUSION: Both prostate and breast cancer were associated with high estimated exposure to outdoor ALAN in the blue-enriched light spectrum. https://doi.org/10.1289/EHP1837.

Title Adaptive light: a lighting control method aligned with dark adaptation of human vision Type Journal Article
Year 2020 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 10 Issue 1 Pages 11204
Keywords Human Health; Vision; Lighting
Abstract Light exposure before sleep causes a reduction in the quality and duration of sleep. In order to reduce these detrimental effects of light exposure, it is important to dim the light. However, dimming the light often causes inconvenience and can lower the quality of life (QOL). We therefore aimed to develop a lighting control method for use before going to bed, in which the illuminance of lights can be ramped down with less of a subjective feeling of changes in illuminance. We performed seven experiments in a double-blind, randomized crossover design. In each experiment, we compared two lighting conditions. We examined constant illuminance, linear dimming, and three monophasic and three biphasic exponential dimming, to explore the fast and slow increases in visibility that reflect the dark adaptation of cone and rod photoreceptors in the retina, respectively. Finally, we developed a biphasic exponential dimming method termed Adaptive Light 1.0. Adaptive Light 1.0 significantly prevented the misidentification seen in constant light and effectively suppressed perceptions of the illuminance change. This novel lighting method will help to develop new intelligent lighting instruments that reduce the negative effect of light on sleep and also lower energy consumption.

Title Lichtverschmutzung – Ausmaß, gesellschaftliche und ökologische Auswirkungen sowie Handlungsansätze Type Report
Year 2020 Publication Abbreviated Journal
Volume 186 Issue Pages 1-200
Keywords Review; Skyglow; Ecology; Human Health; Lighting; Public Safety; Remote Sensing
Abstract Künstliches Licht kann als eine der größten technischen Errungenschaften der Menschheit angesehen werden, die erhebliche Veränderungen bzw. Fortschritte der Arbeits- und Lebensweisen ermöglichen. Mit künstlicher Beleuchtung wird aber auch der natürliche Rhythmus von Tag und Nacht verändert und damit das Gesamtgefüge des Naturhaushaltes und der Nachtlandschaft transformiert. Ein natürlich dunkler Nachthimmel ist in Deutschland selten geworden. Licht-glocken über urbanen Gebieten sind weit weg von ihrem Entstehungsort in unbeleuchteten Gebieten noch sichtbar und lassen Sterne und die Milchstraße unkenntlich werden. Nicht nur das direkte elektrische Licht erleuchtet unsere Umwelt, sondern auch der nach oben abgestrahlte und reflektierte Teil des Lichts. Schichten der Atmosphäre, Staub oder Wassertropfen reflektieren und streuen das Licht. Dieser auch als Skyglow bezeichnete Effekt bewirkt eine zusätzliche Erhellung. Neben dieser künstlich erhöhten Himmelshelligkeit kann Licht auch die direkte Umgebung ungewollt aufhellen oder durch Blendung das Sehen einschränken. Licht ist ein wichtiger externer Zeitgeber für die innere Uhr der Lebewesen, an dessen natürlichen Rhythmus sich Menschen, Tiere und Pflanzen über Jahrhunderte angepasst haben. So wird vermutet, dass die permanent und periodisch veränderten Lichtverhältnisse durch zunehmende künstliche Beleuchtung negative Auswirkungen auf die menschliche Gesundheit haben und ebenso zu ökologischen Beeinträchtigungen führen.All diese nichtintendierten Wirkungen der künstlichen Beleuchtung werden unter dem Sammelbegriff Lichtverschmutzung verstanden. Lichtverschmutzung ist hier definiert als unerwünschte Wirkung künstlicher Beleuchtung im Außenbereich, also das Licht, das räumlich (Richtung und Fläche), zeitlich (Tages- und Jahreszeit, Dauer, Periodizität) oder in der Intensität oder spektralen Zusammensetzung (z.B. Ultraviolett- oder Blauanteil) über den reinen Beleuchtungszweck hinaus nicht beabsichtigte Auswirkungen hat (Kuechly et al. 2018). Mit dem vorliegenden Bericht werden der wissenschaftliche Erkenntnis-stand im Hinblick auf Umfang und Trends der Lichtverschmutzung sowie ihre wirtschaftlichen und soziokulturellen, humanmedizinischen und ökologischen Wirkungen zusammengefasst. Auf Basis dieser Erkenntnisse und aktueller beleuchtungstechnologischer und lichtplanerischer Möglichkeiten werden Handlungsoptionen abgeleitet, die eine Verringerung der Lichtverschmutzung bei gleichzeitiger Berücksichtigung der nutzbringenden Ziele der Beleuchtung unterstützen können.

Title Dramatically altered environmental lighting conditions in women with high-risk pregnancy during hospitalization Type Journal Article
Year 2020 Publication Chronobiology International Abbreviated Journal Chronobiol Int
Volume in press Issue Pages
Keywords Lighting; Human Health; Pregnant women; circadian rhythm; color temperatures; hospital light environmental; illuminance; indoor
Abstract The maternal circadian time structure is incredibly important in the entrainment and programing of the fetal and newborn circadian time structure. Natural sunlight is the primary environmental time cue for entrainment of circadian rhythms, but high-risk pregnant women spend most of their time indoors with artificial light sources and extremely low levels of natural light both during the day and night. Because the daily level, timing, duration of light exposure and its spectral properties are important in maintaining the normal circadian physiology in humans, we aimed to evaluate the environmental lighting conditions in high-risk pregnant women admitted to hospital for long-term stay. About 30 patients were included in the study. Exposed illuminance, color temperature and effective circadian radiation dose were measured and recorded every 10 s by light dosimeters attached to the patients' clothing. We documented the illuminance of 29 pregnant women on 235 inpatient days. Median (IQR) measured illuminance was 70 (28-173) lux in the morning, 124 (63-241) lux in the afternoon, 19 (6-53) lux in the evening and 0 (0-0) lux at the night. Median illuminance for the 235 inpatient days of assessment was below the recommended EU standard of 100 lux-60.5% of the mornings and 42.7% of the afternoons. The women confined to indoor locations rarely achieved an illuminances more than 300 lux in the morning and in the afternoon. Compared to women with outdoor mobility, those confined indoors have a significantly lower illuminance and color temperature, both in the morning and in the afternoon. Our study presents the first information about the dramatically altered environmental lighting conditions experienced by high-risk pregnant women during their hospital stay. Their exposure to light while in the hospital is significantly lower than exposure to natural daylight levels and below the recommended EU standard.
