  Title Evaluating Human Photoreceptoral Inputs from Night-Time Lights Using RGB Imaging Photometry Type Journal Article
  Year 2019 Publication Journal of Imaging Abbreviated Journal J. Imaging  
  Volume 5 Issue 4 Pages 49  
  Keywords Human Health; Remote Sensing; Instrumentation  
  Abstract Night-time lights interact with human physiology through different pathways starting at the retinal layers of the eye; from the signals provided by the rods; the S-, L- and M-cones; and the intrinsically photosensitive retinal ganglion cells (ipRGC). These individual photic channels combine in complex ways to modulate important physiological processes, among them the daily entrainment of the neural master oscillator that regulates circadian rhythms. Evaluating the relative excitation of each type of photoreceptor generally requires full knowledge of the spectral power distribution of the incoming light, information that is not easily available in many practical applications. One such instance is wide area sensing of public outdoor lighting; present-day radiometers onboard Earth-orbiting platforms with sufficient nighttime sensitivity are generally panchromatic and lack the required spectral discrimination capacity. In this paper, we show that RGB imagery acquired with off-the-shelf digital single-lens reflex cameras (DSLR) can be a useful tool to evaluate, with reasonable accuracy and high angular resolution, the photoreceptoral inputs associated with a wide range of lamp technologies. The method is based on linear regressions of these inputs against optimum combinations of the associated R, G, and B signals, built for a large set of artificial light sources by means of synthetic photometry. Given the widespread use of RGB imaging devices, this approach is expected to facilitate the monitoring of the physiological effects of light pollution, from ground and space alike, using standard imaging technology.

  Title Sustainable Lighting and Light Pollution: A Critical Issue for the Present Generation, a Challenge to the Future Type Journal Article
  Year 2020 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 12 Issue 11 Pages 4552  
  Keywords Society; light pollution measurement and modelling; light pollution impact on fauna and flora; light pollution impact on human health; policies to prevent/limit light pollution and territorial management; best practices for street lighting with low impact on light pollution; smart lighting and light pollution  
  Abstract Human beings’ poor night vision and primitive fear of the dark are reflected in an imperative need to use artificial light to illuminate their environment. Outdoor illumination undoubtedly contributes to the enhancement of practical opportunities for social and economic developments. Considered as a necessity, a means of security, and an attraction or valorization, city lighting growth has been literally exponential in the last half century. Beyond the financial and energy resources that it absorbs, the artificial lighting of urban spaces overflows its objective by polluting our nights to the point that, in our modern megacities, the stars disappear. Apart from the fact that stars are no longer visible, the scientific community is increasingly interested in the direct and indirect impacts of artificial lighting on biodiversity. In parallel, some studies have shown recently that stray light may have direct or indirect effects on human health and mood. The scope of this Special Issue, dedicated to the memory of Prof. Abraham Haim and Dr. Thomas Posch, is to put together a series of high-level papers treating light pollution in a holistic manner that goes from technological advances to policies, passing through impacts on biotopes and human health. Beyond its evident scientific interest, this Special Issue is also contributing to awareness raising, aimed at decision- and policy-makers.

  Title Towards a Sustainable Indoor Lighting Design: Effects of Artificial Light on the Emotional State of Adolescents in the Classroom Type Journal Article
  Year 2020 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 12 Issue 10 Pages 4263  
  Keywords Human Health; *Conservation of Natural Resources; visual comfort; artificial lighting; indoor lighting design; chronodisruption; circadian rhythms; daylighting; sustainable lighting design; LED luminaires; indoor environment quality; classroom lighting  
  Abstract In recent years, articles have been published on the non-visual effects of light, specifically the light emitted by the new luminaires with light emitting diodes (LEDs) and by the screens of televisions, computer equipment, and mobile phones. Professionals from the world of optometry have raised the possibility that the blue part of the visible light from sources that emit artificial light could have pernicious effects on the retina. The aim of this work is to analyze the articles published on this subject, and to use existing information to elucidate the spectral composition and irradiance of new LED luminaires for use in the home and in public spaces such as educational centers, as well as considering the consequences of the light emitted by laptops for teenagers. The results of this research show that the amount of blue light emitted by electronic equipment is lower than that emitted by modern luminaires and thousands of times less than solar irradiance. On the other hand, the latest research warns that these small amounts of light received at night can have pernicious non-visual effects on adolescents. The creation of new LED luminaires for interior lighting, including in educational centers, where the intensity of blue light can be increased without any specific legislation for its control, makes regulatory developments imperative due to the possible repercussions on adolescents with unknown and unpredictable consequences.

  Title Preventive Effect of Morning Bluish LED Light on Light-induced Melatonin Suppression at Night Type Journal Article
  Year 2018 Publication Journal of Science and Technology in Lighting Abbreviated Journal  
  Volume 41 Issue Pages 206-210  
  Keywords Human Health  
  Abstract Bright nocturnal light has been known to suppress melatonin secretion. However, bright light exposure during daytime might reduce light-induced melatonin suppression (LIMS) at night. This study aims to evaluate the effect of high correlated color temperature LED light during daytime on LIMS. Male participants were exposed to different light conditions for 3 h in the morning (09:00â??12:00). The light conditions were dim light (<10 lx), 125 lx high correlated color temperature (CCT) LED light, and 250 lx high CCT LED light. The subjects were then exposed to bright light (white light, 300 lx) for 1.5 h at night (01:00â??02:30). Saliva samples were taken before (01:00) and after (02:30) exposure for evaluation of melatonin secretion. There were no significant differences in melatonin secretion before and after night-time light exposure on the 125 lx and 250 lx morning light conditions. Since these light intensities were almost equal to those in our previous study, the high CCT LED light might be appropriate for certain work places (e.g., hospitals and underground spaces), contributing to the reduction of our health risk and also saving energy.
