  Title Comparative analysis of HPS and LED luminaries in terms of effectiveness of greenhouse plant lighting and light emission Type Journal Article
  Year 2019 Publication IEEE Xplore Abbreviated Journal (up)  
  Volume Issue Pages  
  Keywords Lighting; Light emitting diodes; LED; Lighting; Sodium; Electromagnetics; Light sources; Color; Production  
  Abstract The article focuses on the analysis of the parameters of light sources, spectrum characteristics of HPS and LED lighting to achieve the best results in greenhouse cultivation with the least energy consumption, and the escape of light into space. The authors have compared both sodium HPS and LED luminaries in the aspect of colour light efficiency and their influence on the plant vegetation process.

  Title MOBILE MAPPING OF NIGHT-TIME ROAD ENVIRONMENT LIGHTING CONDITIONS Type Journal Article
  Year 2018 Publication The Photogrammetric Journal of Finland Abbreviated Journal (up)  
  Volume 26 Issue 1 Pages  
  Keywords Lighting; Remote Sensing  
  Abstract The measurement of 3D geometry for road environments is one of the main applications of mobile mapping systems (MMS). We present mobile mapping applied to a night-time road environment. We integrate the measurement of luminances into a georeferenced 3D point cloud. The luminance measurement and the 3D point cloud acquired with an MMS are used in assessing road environment lighting conditions. Luminance (cd/m2) was measured with a luminance-calibrated panoramic camera system, and point cloud was produced by laser scanners. The relative orientation between the GNSS, IMU, camera, and laser scanner sensors was solved in order to

integrate the data sets into the same coordinate system. Hence, the georeferenced luminance values are transferable into geographic information systems (GIS). The method provides promising results for future road lighting assessment. In addition, this article demonstrates the night-time mobile mapping principle applied to a road section in Helsinki, Finland. Finally, we discuss the

future applications of mobile-mapped luminance point clouds.

  Title Assessing Public Perceptions about Road Lighting in five Neighborhoods of Tirana, Albania Type Journal Article
  Year 2019 Publication Abbreviated Journal (up)  
  Volume Issue Pages  
  Keywords Public Safety; Psychology; Roadway lighting; Albania; Europe  
  Abstract Lighting is essential for sight, human health and well-being, emerging the need for assessing exterior lighting to better understand how far public is satisfied about exterior lighting. Exterior lighting was assessed in five major roads of the capital city of Tirana, Albania, in November 2017. Security, obstacle detection and visibility were evaluated using questionnaires for road lighting. The approximately 87 and 60 percent of respondents, respectively, were not able to detect a pavement obstacle after-dark and to distinguish a

familiar face at a distance of 5 m and 10 m along roads. Road lighting after-dark was unsatisfactory to 60 percent of respondents. These findings identified road lighting could be inadequate for users, requiring further investigation and new data collection of road lighting in neighborhoods of Tirana.

  Title What is French about the “French fear of darkness”? The co-production of imagined communities of light and energy Type Journal Article
  Year 2019 Publication Journal of Energy History Revue d'Histoire de l'Energie Abbreviated Journal (up)  
  Volume 2 Issue Pages  
  Keywords History; Society; Energy; Lighting; France  
  Abstract This essay takes expert assumptions about light preferences as a starting point for a historical inquiry into what I call imagined sociotechnical communities of light and energy. My argument is that historical energy supply systems produced these imaginaries and vice versa, shifting the scales at which public lighting was envisioned and darkness was acceptable. While in the 17th C. dark streets were the norm and even the illumination of single streets was publically contested, innovators of the 18th C. imagined gas light and energy on an urban scale. In the 20th C., electric lighting promoted electrification and the electricity supply systems in countries like France allowed experts to think and standardize lighting at a national level. In the 21st C. the expert imaginary of a light-loving French people is challenged by public environmental concern.

  Title Pedestrian Lighting, Acceptable Levels of Light: A Pilot Project Type Journal Article
  Year 2019 Publication Institute for Public Administration Abbreviated Journal (up)  
  Volume Issue Pages  
  Keywords Lighting; Public Safety; Security  
  Abstract This pilot project study was intended to demonstrate that assessing the adequacy of an area’s pedestrian lighting need not be an expensive, time-consuming, or overly complicated process. Though the discussion of methods of pedestrian lighting can become quite technical and involved, as demonstrated in a 2016 IPA report on the topic, “Delaware Transportation Lighting Inventory & Assessment” (http://www.ipa.udel.edu/publications/transportationlighting-2016.pdf), simply observing and recording light levels in a given study area is quite straightforward.
