  Title (down) The “layered method” – A third method of floodlighting Type Journal Article
  Year 2019 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology  
  Volume Issue Pages in press  
  Keywords Lighting  
  Abstract The main aim of this work is to present a new method of floodlighting – the ‘Layered Method’. It has been possible to create this method due to the rapid development of linear luminaires with LEDs. When luminaires are located a very short distance from an illuminated wall and are directed at a low angle, the layered floodlighting method gives an unusual and interesting visual effect. In this situation, the length of light distribution on the illuminated wall is the same as the length of the light line and is rather short in width. This gives the opportunity of creating the effect of a layer of light, which can be used, for example, to illuminate Renaissance tenement houses and all types of longitudinal architectural details, such as tympanums or balusters. This paper presents the state-of-the-art use of the layered method of floodlighting. All advantages and disadvantages, in terms of lighting technology and architecture, are carefully described. The ideas contained in this paper could be useful for those who are interested in making architectural objects more beautiful by means of illumination at night-time.

  Title (down) The Value of Red Light at Night for Increasing Basil Yield Type Journal Article
  Year 2018 Publication Canadian Journal of Plant Science Abbreviated Journal Can. J. Plant Sci.  
  Volume 98 Issue 6 Pages 1321-1330  
  Keywords Plants  
  Abstract Sweet basil (<i>Ocimum basilicum L.</i>) is primarily used for culinary purposes, but it is also used in the fragrance and medicinal industries. In the last few years, global sweet basil production has been significantly impacted by downy mildew caused by <i>Peronospora belbahrii</i>. Nighttime exposure to red light has been shown to inhibit sporulation of <i>P. belbahrii</i>. The objective of this study was to determine if nighttime exposure to red light from light-emitting diodes (LEDs; λ<sub>max</sub> = 625 nm) could increase plant growth (plant height and leaf size) and yield (number and weight of leaves) in basil plants. In two sets of greenhouse experiments, red light was applied at a photosynthetic photon flux density (PPFD) of 60 µmol m<sup>-2</sup> s<sup>-1</sup> during the otherwise dark night for 10 hours (from 20:00 to 06:00). The results demonstrate that exposure to red light at night can increase the number of basil leaves per plant, plant height, leaf size (length and width), and leaf fresh and dry weight, compared to plants in darkness at night. The addition of incremental red light at night has the potential to be cost-effective for fresh organic basil production in controlled environments.

  Title (down) The Value of Darkness: A Moral Framework for Urban Nighttime Lighting Type Journal Article
  Year 2018 Publication Science and Engineering Ethics Abbreviated Journal Sci Eng Ethics  
  Volume 24 Issue 2 Pages 607-628  
  Keywords Darkness; Society  
  Abstract The adverse effects of artificial nighttime lighting, known as light pollution, are emerging as an important environmental issue. To address these effects, current scientific research focuses mainly on identifying what is bad or undesirable about certain types and uses of lighting at night. This paper adopts a value-sensitive approach, focusing instead on what is good about darkness at night. In doing so, it offers a first comprehensive analysis of the environmental value of darkness at night from within applied ethics. A design for values orientation is utilized to conceptualize, define, and categorize the ways in which value is derived from darkness. Nine values are identified and categorized via their type of good, temporal outlook, and spatial characteristics. Furthermore, these nine values are translated into prima facie moral obligations that should be incorporated into future design choices, policy-making, and innovations to nighttime lighting. Thus, the value of darkness is analyzed with the practical goal of informing future decision-making about urban nighttime lighting.
