Title Analysis of light pollution from floodlighting: Is there a different approach to floodlighting? Type Journal Article
Year 2017 Publication Light and Engineering Abbreviated Journal
Volume 25 Issue 1 Pages 75-82
Keywords LED lighting
Abstract The research which was prepared for this paper was inspired by a real floodlit object. The main distinctive feature is connected with the directionality of its lighting. The „Sezam” building was one of the first to be illuminated in the opposite way to the usual manner of floodlighting. The analysis, based on the measurement of horizontal illuminance on the pavement in front of the building andof theluminance on the facade, leads to some very unusual conclusions. It goes deeper than merely the assessment of the phenomenon of light pollution in the context of floodlighting. Additionally, a short survey about the preferences of lighting directionality in floodlighting and the general concept of light pollution was conducted on a group of over a dozen people. It turned out that people are quite aware of the phenomenon of light pollution and they rather prefer illumination from floodlighting to be from bottom to top.

Title Illuminating prey selection in an insectivorous bat community, exposed to artificial light at night Type Journal Article
Year 2018 Publication Journal of Applied Ecology Abbreviated Journal
Volume 55 Issue 2 Pages 705-713
Keywords Animals; Ecology
Abstract 1.Light pollution has been increasing around the globe and threatens to disturb natural rhythms of wildlife species. Artificial light impacts the behaviour of insectivorous bats in numerous ways, including foraging behaviour, which may in turn lead to altered prey selection.

2.In a manipulative field experiment, we collected faecal samples from six species of insectivorous bats in naturally dark and artificially lit conditions, and identified prey items using molecular methods to investigate effects of light pollution on prey selection.

3.Proportional differences of identified prey were not consistent and appeared to be species specific. Red bats, little brown bats, and gray bats exhibited expected increases in moths at lit sites. Beetle-specialist big brown bats had a sizeable increase in beetle consumption around lights, while tri-colored bats and evening bats showed little change in moth consumption between experimental conditions. Dietary overlap was high between experimental conditions within each species, and dietary breadth only changed significantly between experimental conditions in one species, the little brown bat.

4.Policy implications. Our results, building on others, demonstrate that bat-insect interactions may be more nuanced than the common assertion that moth consumption increases around lights. They highlight the need for a greater mechanistic understanding of bat-light interactions to predict which species will be most affected by light pollution. Given differences in bat and insect communities, we advocate biologists, land stewards, and civil planners work collaboratively to determine lighting solutions that minimize changes in foraging behaviour of species in the local bat community. Such efforts may allow stakeholders to more effectively craft management strategies to minimize unnatural shifts in prey selection caused by artificial lights.

Title Phosphor-converted LEDs with low circadian action for outdoor lighting Type Journal Article
Year 2014 Publication Optics Letters Abbreviated Journal Opt Lett
Volume 39 Issue 3 Pages 563-566
Keywords LED; light emitting diode; phosphor conversion; firelight; circadian disruption
Abstract Dichromatic phosphor-converted (pc) light-emitting diodes (LEDs) with low circadian action are proposed for low-luminance photobiologically safe outdoor illumination. The LEDs feature the partial conversion of blue radiation in an orange phosphor with the resulting correlated color temperature in the “firelight” range of 1700-2500 K. The circadian action factor, which is the ratio of the biological efficacy of radiation due to the excitation of intrinsically photosensitive retinal ganglion cells to the mesopic luminous efficacy of radiation, is considerably lower than that of commercial white pc LEDs. The equivalent general color-rendering index estimated with regard to the reduced color-discrimination ability of human vision at low luminances has appropriate values in between those of common white pc LEDs and high-pressure sodium lamp.

Title Study on the Standard Guideline of Environmental Impact Assessment Focusing on Light Pollution 빛공해 분야의 환경영향평가 지침 표준화 연구 Type Journal Article
Year 2019 Publication Journal of Environmental Impact Assessment (환경영향평가) Abbreviated Journal
Volume 28 Issue 1 Pages 63-70
Keywords Planning
Abstract Artificial lighting is an essential part, but it causes light pollution due to unnecessary or excessive use of light. Light pollution has negative effects such as power waste, adverse health effects, destruction of the ecosystem. But currently, light pollution is managed only post-management. The purpose of this study is to standardize methods of environmental impact assessment focusing on light pollution to effectively manage and reduce the negative effect of areas that may cause light pollution in advance.
